Technical & Industry Knowledge Base

The use and promotion of concrete paving and leveling machines has ended the traditional construction of using mortar to punch piers, finding elevations, laying out side formwork, dump trucks to transport concrete, manual preliminary leveling, scraping with flat plates, and vibrating concrete with vibrators. Then a special double-row steel pipe is used to vibrate and tamp and level it back and forth. So how much do you know about this device? Next, I will give you a detailed introduction to the basic configuration of the concrete paving and leveling machine equipment. Let's learn more about it together. The basic configuration of concrete paving and leveling machine equipment is introduced in detail as follows: 1. The laser leveling machine uses precision laser technology, closed-loop control technology and a highly precise integrated hydraulic system, and is realized under the automatic control of a microcomputer. This is what distinguishes it from other floor construction techniques. 2. The concrete paving and leveling machine relies on a hydraulically driven leveling mechanism and cooperates with the laser system and computer control system to complete the leveling work while automatically leveling. 3. The laser transmitter used by the concrete leveling machine to control the ground elevation is independently arranged, and the floor elevation will not produce cumulative errors. Compared with traditional methods, the construction joints on the floor can be greatly reduced, and the subsequent maintenance costs of the ground and the use of formwork are also greatly reduced. 4. The laser transmitter equipped with the concrete paving and leveling machine can automatically control both the plane and the two-way slope. It is also completed by the laser system, microcomputer system, hydraulic system, and mechanical and electronic system. For complex-shaped floors with high requirements such as drainage, a three-dimensional special-shaped ground treatment system can also be selected. 5. Using solid anti-puncture tires, paving and leveling operations can be performed directly on the steel mesh. 6. The concrete paving and leveling machine comes with a high-pressure cleaning system, which greatly facilitates the cleaning of the bonded concrete on the machine, ensures the normal use of the machine, and extends the service life of the machine. Scope of application: Laser leveling machines are developed based on the increasing demand for ground quality such as strength, flatness, and levelness in modern industrial plants, large shopping malls, warehouses, and other large-area cement concrete floors. Indoor floors: ① Modern large-scale industrial plants, workshops, and automated three-dimensional warehouses. ②. Clean factories for electronic appliances, food materials, medicine, etc. ③, Large-scale warehouse supermarkets, logistics centers, convention and exhibition centers, etc. Outdoor floors: ①, terminals, container yards, freight yards, ②, airport runways, aprons, parking lots, ③, squares, residential floors, municipal roads, etc.

Nowadays, the amount of work is increasing. When operating the concrete laser leveling, you will feel that the fuel consumption of the machine is a bit high. This is because the workload itself is relatively large, and the construction time is also relatively long, so the fuel consumption is It is also a relatively common phenomenon, but in order to further save costs, we still need to take some measures, which can actually reasonably reduce the fuel consumption of concrete laser leveling machines. 1. Be proficient in the operation method of concrete laser leveling machine In order to reduce the unnecessary increase in fuel consumption in the concrete laser leveling machine, you must first understand the basic operations of the concrete laser leveling machine and master the correct operations of loading, walking, turning, leveling, slope repair and other operations. If the foundation is not good, it will increase the fuel consumption of the concrete laser leveling machine. I would like to remind novices who have just entered the industry to listen to the advice of the master and master the leveling operation. 2. Reduce unnecessary idling If you want to save fuel, you need to reduce the necessary idling speed of the engine. You should know that when the concrete laser leveling is idling, it is also using a hydraulic pump to circulate hydraulic oil. The longer the idling time, the more fuel is wasted. In fact, the correct way to save fuel is to try not to idle the concrete laser leveler during standby and rest periods. This is one of the secrets to saving fuel. 3. Reduce engine speed When performing excavation operations, when the engine speed is at a higher speed, the operating speed is fast, but the fuel consumption is high. When operating at non-full throttle, appropriately reduce the engine speed. Although the operating speed is reduced, fuel consumption can be reduced. Improve fuel efficiency. 4. Walking without full throttle When walking with the engine not at full throttle, everyone should know that the higher the engine speed, the faster the walking speed, and the higher the fuel consumption. Reducing the engine speed during operation can improve fuel consumption efficiency while walking.

Laser leveling machines have high requirements and standards for road surface smoothness. When performing road surface smoothing, the requirements for smoothness are still relatively high. This is because the smoothness of the road surface also plays a big role in the beauty of the environment. Generally speaking, if manual leveling is used, the effect will not be very good. Fortunately, there are laser leveling machines now, and many construction units have also chosen laser leveling machines for road smoothing operations. So laser leveling machines How does it achieve such excellent leveling effect? Laser leveling machines have high requirements and standards for road smoothness 1. Control of the laser leveling machine's baseline: When the leveling machine performs automatic leveling, it needs an accurate reference surface. Generally, when the main focus is to control the height, the tightrope method is suitable; when the main focus is to control the thickness, the floating datum beam method is adopted. Generally, tightrope is used for the bottom layer, and floating datum beam method is used for the middle layer and surface layer. The benchmark wire rope method is to install benchmark wire ropes on both sides of the road, but note: the spacing between the pillars and steel bars supporting the steel wire ropes cannot be too large, generally 5-10m; the steel bars should be 1-2mm higher than the design elevation, and the elevation of the steel bars must be ensured when laying Always accurate during the construction process. 2. Paving speed control of laser leveling machine: The leveling machine should work at a constant speed without stopping, and it is strictly forbidden to be fast and slow. During the leveling process, stoppages should be avoided as much as possible, and the necessary daily stoppages should be placed at the location where the contraction joint is scheduled to be made at one end of the structure. In case of shutdown in the middle, the leveling of the leveling should be locked to prevent it from sinking; when the mixture temperature is above 100°C, the pause time should not exceed 10 minutes. When the pause time exceeds 30 minutes or the mixture temperature is below 100°C, Re-seam according to the method of treating cold seams 3. Laser leveling machine operation control measures: Skill ed laser leveling machine operators should be selected and given pre-job training; during the paving process, the material transport truck should stop 10-30m away from the laser leveling machine and In neutral gear, rely on the laser leveler to push forward slowly, and there should be a dedicated person to direct the unloading truck to unload; ensure the continuity of the work of the leveling machine's feeding system, that is, ensure the height of the material level in the casters (conveyor wheels) Stable, uniform and continuous, the material level height should be kept at 2/3 of the blade above the central axis. Before construction, the leveling must be cleaned. After adjusting the height and cross slope of the leveling, preheat the leveling. The preheating temperature of the leveling should be close to the temperature of the asphalt mixture, which can generally be heated to 85°C-90°C.

If the concrete laser leveling machine works in the summer, it will need to face hot temperatures for a long time. However, if the leveling machine is always under high temperature, it will actually cause many adverse reactions. For example, the tires will be more likely to be damaged or The water in the water tank will evaporate at an accelerated rate, so in order to protect the concrete laser leveler, when you need to operate the leveler at high temperatures, you should take appropriate precautions in advance. How to take precautions when the concrete laser leveling machine works under high temperature conditions ●First, because the summer is hot and the temperature is continuous, so if the concrete laser leveling needs to work for a long time, it means that the vehicle tires are always exposed to high temperatures. At this time, you should pay attention to the tires caused by high temperatures. Rubber softening problem. Moreover, if you encounter sharp objects during the work, a tire blowout may occur. Therefore, this requires car owners to check the air pressure level in the tires in advance before the concrete laser leveling machine is working. If the tire temperature is found to be relatively high during the work, appropriate cooling measures need to be taken. There are two misunderstandings to avoid here. The two cooling measures of directly pouring cold water and deflating the air are very undesirable because they will cause damage to the tires and even cause a puncture later. ●Second, if the concrete laser leveling machine works under high temperature conditions for a long time, the water in the water tank will evaporate more quickly, so the owner should pay more attention to how much cooling water is left and what temperature the water temperature meter shows. , if you find that the water volume is not enough, you should stop the car immediately, but you cannot add water immediately at this time, but you should add water after the temperature has cooled down a little. When adding water, be careful to avoid burns. ●Third, ther e are two particularly dangerous time periods that require more vigilance, mainly at noon and dusk. After a morning of working with the concrete laser leveling, especially in summer when the temperature is high, people can easily become sleepy during the noon period, which can lead to fatigue driving and lack of concentration, so accidents often occur. It is also easier to get tired at dusk because of the hard work of the day. In this case, the car owner can drink something refreshing, or stop and rest, and then continue the work of the concrete laser leveling machine when his mental state is better.

Early treatment to ensure safety: The application of laser leveling machines has been very extensive. It can be said that leveling machines are required in all places where floor construction is required, because the effect of using leveling machines for floor construction is great. Very good, the ground is compacted flat and dense, that's why so many people like to use laser leveling machines for work. Of course, some faults will also occur during the work of the leveling machine. Let's learn about the following two common faults. ★★Hydraulic oil overheating: If the oil temperature of the hydraulic system of the laser leveling machine is too high, the viscosity of the oil will decrease, the amount of leakage will increase, the oil film on the lubricated parts will be destroyed, and the wear of the components will increase; at the same time, high temperature will also cause rubber and other materials to The resulting gasket is damaged due to premature aging. Therefore, it is very important to control the appropriate oil temperature. When the oil temperature is too high, the laser leveling machine must be shut down for inspection. ▲Generally, we can start from the following aspects: 1. Check whether the liquid level in the fuel tank is too low. Experience shows that high oil temperature is often caused by a lack of oil in the fuel tank, so it should be replenished in time when there is a lack of oil. 2. Whether the hydraulic oil filter element and circuit are blocked. 3. Is the radiator of the laser leveling machine normal? If a large amount of dust adheres to the radiator, it can lead to poor heat dissipation and increase the oil temperature. Since the working environment of the laser leveling machine is dusty, the radiator should be cleaned in time. 4. Whether the quality of hydraulic oil is qualified. If the quality of the added oil is not up to standard, it will also cause the system oil temperature to be too high. In addition, when the hydraulic system works when there is a lack of oil, it is easy to cause damage to the pump and motor. Therefore, after troubleshooting the oil shortage, you must also check the operating status of the pump and motor, and replace damaged parts of the pump and motor if necessary. ★★The spiral distributor does not work: Sometimes the left and right distributors of the laser leveling machine do not work. The reason is usually that the oil supply system is faulty. The reasons for low pressure in the oil charge system include: poor oil inlet passage of the oil charge pump; low pressure in the relief valve of the oil charge pump; failure of the oil charge pump itself; and serious leakage of the hydraulic motor. Generally, you should focus on checking the charge pump and its relief valve. Hydraulic oil should be filled in a clean container before being added to the hydraulic oil tank. The hydraulic oil must be filtered by an oil filter before being added to the hydraulic oil tank; the replacement cycle of the hydraulic oil depends on the quality of the oil used (generally replaced once every 1000 hours); replacement Hydraulic oil should be used at working temperature; in order to ensure good heat dissipation of the hydraulic system, the hydraulic oil radiator should also be cleaned regularly.

The cold wave is coming and the temperature drops sharply. In order to reduce the impact of low temperature on the laser leveling machine equipment, Wanshi Friendly reminds you to do a good job in keeping the laser leveling machine cold and warm to prevent "frostbite" incidents of the equipment, so as to avoid inconvenience to you. or cause unnecessary losses. The cold wave is coming, how to maintain the laser leveling machine in winter? 01 "Great health care" in the off-season, "Roll up your sleeves and do it" in the peak season When the winter cold wave hits, floor construction gradually enters the off-season, and the laser leveling machine is parked for a long time. It is necessary to pay attention to "equipment maintenance" and ensure that the laser leveling machine equipment is in good working condition at all times, so that it can be used for the first time when the construction peak season arrives. Invest in on-site work at once to seize market opportunities. However, low-temperature construction in winter is also a huge challenge and test for concrete and concrete laser leveling machines.

Speaking of after-sales service, in fact, the after-sales service of the entire flooring industry has always been lacking. When there is a problem with a customer's equipment, there is always the problem of the manufacturer not responding in time, or even not responding at all. There have been many customers in the past who were unable to receive timely after-sales service due to problems when purchasing concrete laser leveling machines from other manufacturers. This not only delayed the construction period, but also caused a certain degree of losses. As a service benchmark in the flooring industry, Wanshi Machinery has always put the needs of customers first and adhered to its "three ones" commitment. In fact, after-sales service is not just about helping customers, but also about helping yourself. For a company, credibility and reputation are crucial, and after-sales service is the cornerstone of credibility and reputation. Wanshi Machinery fulfills the Three Ones promise, "response within a quarter of an hour, arrive within one day, and solve the problem within one day."

With the advent of laser leveling machines, are you still using the old vibrating leveler to vibrate the beam? When it comes to construction, everyone knows that only with a short construction period and high quality can we save costs, improve efficiency and increase profits. If you want to save costs quickly during construction, construction tools are a very important choice. An efficient, convenient and fast tool will make construction work more effective with half the effort! On the contrary, choosing inappropriate tools will extend the construction period, increase costs, and reduce profits. Take the floor construction under construction as an example! The flatness of the floor is more difficult to grasp. Leveling is usually done manually. Even if you use an old-fashioned floor machine, the effect and cost are not particularly ideal. The emergence of a laser leveling machine has greatly solved many problems that arise during construction. During the construction process, it can solve the problems of hollowing, shelling, cracking, and uneven ground after general construction. It can make the final effect exceed Party A's floor quality requirements, reduce costs, and Improved work efficiency. Many industries require factories, as well as shopping malls, large warehouses and other construction sites that require large areas of ground, to have much higher standards. Attention has been greatly increased to the strength, flatness and level of the ground quality. It is difficult to meet the requirements using old-fashioned flooring methods, and labor costs will increase exponentially. The construction principle of the laser leveler is very simple and clear. It can perform several construction processes such as leveling and vibration at the same time, further ensuring the quality of the construction and completely saving labor costs. The advantage of construction is that the construction speed is fast and the quality is high, ensuring that the overall integrity of the ground is good and cracks are not prone to occur. The amount of support and disassembly is reduced compared with the traditional method. Moreover, the reduction in the number of workers ensures an increase in final profits.

With the continuous development of the world economy and the continuous increase of the world's population, the construction industry is also booming. The technical level of the construction industry continues to improve. Take floor construction for example! In the past, our floors may have been finished manually, but now laser leveling machines have appeared. It is completely suitable for occasions that could only be handled manually. However, with the rapid development of the economy, there are more and more such machines, so that people do not know how to choose them. So how do we choose a cost-effective machine? It should not be difficult for us to know that there is a concrete laser leveling machine used for large-area floor construction, so we first need a machine with a small flatness error to complete the project to avoid major changes in the entire project due to a small error. So the second question is, how long will it take us to complete such a large-area project? Therefore, we have to choose a machine with a large workload. For example, Wanshi has a small machine that can complete an area of more than 1,500 square meters in just half a day. It is a good choice in this regard. Finally, it's cost-effectiveness. Many machines are high-priced but low-profile equipment, which costs a lot of money. Well, according to my experience, when constructing a building and watching their workers complete the construction bit by bit, using a small laser leveling machine, the entire project is very beautiful. . Although this small machine has a small body and head, it does have a great effect. Therefore, this type of small machinery is very popular on the market now, and it can also be recycled, recycled and disassembled to meet individual needs.

Compared with manual work, laser leveling machines are more efficient and effective, so more and more people are choosing laser leveling machines. So do you know why the price difference between laser leveling machines is so big? The editor will give you a brief introduction, let's take a look. The main reason why the prices of laser leveling machines vary in the market is the difference in quality and brand. Many products look very similar, but when you actually use them, you will find that these products actually seem to be somewhat different. Learn to conduct a comprehensive analysis of the quality of the products, so that you can better Make sure you end up buying a good product. Of course, you still have to make comparisons when faced with different prices. Features of an excellent laser leveler: 1. The leveling principle of the laser leveling machine is achieved by using precision laser technology, closed-loop control technology and a highly precise hydraulic system, under the automatic control of a computer. This is its most prominent feature that distinguishes it from other floor construction processes. . 2. The leveling principle of the laser leveling machine is to rely on the hydraulically driven leveling head to cooperate with the laser system and computer control system to complete the leveling work while automatically leveling. The leveling head is equipped with an integrated scraper, vibrator and leveling plate, which integrates all leveling, leveling, vibration and compaction work into one and completes it at one time. The computer control system automatically adjusts the height 10 times per second in real time, and the balanced designed vibrator has a vibration frequency of 3,000 times per minute. 3. The laser transmitter used to control the ground elevation is arranged independently. In this way, the floor elevation is not controlled by the template and does not produce cumulative errors. 4. The laser leveling machine can also automatically control the longitudinal and transverse slopes, which is also completed by the laser system, computer system, hydraulic system and mechanical system. For complex-shaped floors with high requirements such as drainage, a three-dimensional special-shaped ground treatment system can also be selected.

In terms of manpower for concrete laser leveling machines, the increase in the total number of migrant workers has begun to decline, but the demand is increasing. At the same time, the particularity of the flooring industry has also caused a new generation of young people to be reluctant to engage in this industry. Under the dual effects, many construction teams have experienced labor shortages. In terms of wages, workers' wages are increasing year by year. The salary of a worker now is equivalent to the salary of 3-4 people five years ago, and it is still increasing. But there is no such problem with machinery. A concrete laser leveling machine only needs to be equipped with 8 people. If there were originally a group of 15 people, nearly half of the labor force could be saved. Based on a worker's daily salary of 200-300 yuan, one piece of equipment can save about 2,000 yuan per day. One-time investment can not only solve the problem of manpower shortage, but also save a lot of labor cost investment. In terms of construction efficiency, Sanren concrete laser leveling machine has unrivaled advantages. A piece of equipment can construct 600-1050 square meters per hour at a normal driving speed of 4-7 meters per minute. Based on 8 hours per shift, one piece of equipment can construct 4,800-8,400 square meters in one shift. Although this value will decrease depending on actual working conditions. But compared to manual construction, the efficiency is within 800 square meters per shift. Mechanical construction can undoubtedly greatly shorten the construction period and save construction costs.

Every piece of equipment needs to be maintained after use, and the concrete laser leveling is no exception. The maintenance work seems simple, but in fact it also hides a big mystery. If the maintenance method is suitable for this equipment, it will It is effective, but if it is not suitable, such maintenance will be in vain and will not play a big role at all. Let's take a detailed look at the main points to master in the maintenance of the equipment. Maintenance points for "special" parts of concrete laser levelings 1. The connection between the supercharger of the concrete laser leveling machine and the inlet and exhaust pipes must be tight without air leakage. If there is air leakage between the exhaust pipe and the exhaust gas turbine, the efficiency of the supercharger will be greatly reduced and the exhaust temperature of the diesel engine will be reduced. The valves and supercharger will be damaged due to sudden increase. Before starting the new engine, the supercharger and supercharger oil filter must be filled with clean oil to ensure that the supercharger bearings can be lubricated as soon as the diesel engine is started. After the car has traveled 8,000 to 10,000km, the supercharger oil filter element must be replaced. 2. Before shutting down the diesel engine of the concrete laser leveling machine, it should be run at idle speed for 3 to 5 minutes to reduce the supercharger speed and temperature, and listen to the sound of the supercharger running. If any abnormality is found, the machine should be stopped for inspection, such as If the supercharger rotor rotates sluggishly and makes sounds of sticking or wear, it must be sent to a qualified repair station for repair. 3. After every 500 hours or 30,000km of concrete laser levelinging, the gap on the supercharger rotor shaft should be checked, and the dust and carbon deposits on the compressor turbine casing and rotor blades should be cleaned. At this time, the turbocharger should be Remove it from the diesel engine and replace the metal gasket between the supercharger exhaust pipe. It is not allowed to use mechanical methods to remove the scale on the rotor parts. Instead, use gasoline or other cleaning fluids for cleaning aluminum parts. 4. The locking nut of the supercharger compressor of the concrete laser leveling machine cannot be disassembled, otherwise the dynamic balance of the supercharger rotor will be destroyed and the supercharger will be damaged. 5. Do not damage or deform the rotating parts of any removed turbocharger, otherwise it will affect the balance of the concrete laser leveling machine turbine, and do not damage any rubber seals.
