What is the principle of leveling machine

CONCRETE LASER LEVELING MACHINE SUMMER MAINTENANCE TIPS In the hot summer, the construction of concrete laser leveling machines has not stopped. The high temperature construction environment in summer is a relatively heavy test for construction machinery and equipment such as concrete laser leveling machines. Therefore, laser leveling machines should be prepared in summer The daily maintenance of the concrete laser leveler has also become very important. Today, the editor of Shandong VANSE will explain to you some construction precautions of the concrete laser leveling machine in summer, for your reference. 1. During construction in summer, the engine must first be prevented from overheating. Generally, the temperature of the engine should not exceed 95°. If the temperature is too high, you should choose a relatively shady location to stop and cool down. The engine hood can be lifted to ventilate and dissipate heat while stopping. 2. Check the amount of cooling water in time. When the water radiator reaches 100°, do not rush to add cooling water. Instead, stop the engine immediately to cool down the engine at idle speed, and then add coolant. 3. The construction temperature is high in summer, and the air pressure and temperature of the tire should be checked frequently. If the tire temperature is too high, it should be stopped in time and placed in a cool place to cool down. Remember to use the wrong method of deflation or pouring cold water to cool down. 4. Frequently check the liquid level of the battery, add distilled water in time, and dredge the vent holes, pay attention to the density of the electrolyte, and maintain a good charging state. 5. Prevent engine deflagration. Before entering the summer, the carbon deposits in the combustion chamber, valve top and other parts should be completely removed to maintain good heat dissipation and normal compression ratio; and the fuel supply advance angle should be checked and adjusted to prevent engine deflagration. 6. Check the temperature of hydraulic oil and hydraulic transmission oil frequently. If the temperature is too high, stop the machine and rest, and do not work at higher temperatures. In short, construction machinery such as concrete laser leveling machines are subjected to the test of long-term continuous operation and are also affected by high-temperature environments during summer construction. Therefore, summer construction must pay attention to the above conditions, and it must be carried out regularly. Routine inspection and maintenance work, which is not only related to the service life of the concrete machine leveler, but also related to the hidden dangers of construction and the smoothness of the concrete laser leveler in work.

    The ability of the concrete laser leveler to improve flatness is its core advantage. It fundamentally changes the traditional way of concrete leveling by combining modern laser technology, hydraulic systems and precision mechanical control. To improve the smoothness of construction,Equipment principles, pre-construction preparation, construction process control and post-construction maintenanceThe following is a detailed explanation of the key measures and principles: Erect alaser transmitter, it will produce a very thin, constantly rotating laser plane (360°). This laser plane is the entire field. Absolute horizontal reference, its accuracy is very high (usually up to ±1mm/10m). On the leveling machineLaser receiver, This laser signal will be captured in real time. The receiver transmits the signal to the leveler in real time.Vehicle control system (computer). The control system compares the actual height received with the preset design elevation and calculates the height difference within milliseconds. The control system immediately passes the calculated dropHydraulic valvesdrive. Hydraulic cylinder, to precisely adjust the height of the scraper. This process is Continuous automatic, the machine is always leveling dynamically and in real time, replacing reliance on human judgment and manual operation and eliminating human errors. Foundation treatment: The compaction and smoothness of the base layer (usually crushed stone or stabilized soil) are crucial. While a laser machine can compensate for minor undulations in the base layer, large undulations can significantly impact the concrete usage and overall quality. The base layer should be evenly compacted with no noticeable bumps or indentations. Laser transmitter installation: The laser transmitter must be firmly installed in a place with minimal interference from construction. Use a precise level to ensure it is absolutely level. Input and verification of elevation： Accurately input the design elevation into the control system. Before construction, the site should be tested at multiple points (especially corners and center) withLaser receiving poleVerify the accuracy of the laser signal to ensure that the entire construction surface is within the effective laser scanning range. Formwork (formwork) control: The top surface elevation and rigidity of the template must meet the requirements. Large errors in template elevation or deformation during pouring will directly affect the operating benchmark of the laser leveling machine. Slump: This is a key metric. The slump of each truckload of concrete must be uniform. Excessive slump variation can lead to varying degrees of aggregate segregation after paving, with some areas being too thin and others too dry. Laser leveling cannot effectively treat this uniformly, resulting in poor flatness after hardening. The ideal slump should be determined based on the floor thickness and reinforcement. Generally, a slump of 140-160mm is recommended for pumped concrete. Adequate concrete supply: Ensure the continuous supply of concrete to avoid the situation where the first poured concrete has initially set due to long waiting time, resulting in cold joints between the concrete and the later poured concrete, thus affecting the overall flatness. Paving thickness: The initial paving concrete material should be 2-3 cm higher than the design elevation to leave operating margin for the leveling machine. Routing method: The operator should be experienced and control the leveling machine to move forward smoothly and at a constant speed, avoiding sudden stops and sudden movements. The paths of adjacent milling discs (scrapers) should overlap to avoid missing parts. Bleeding water treatment: If the concrete bleeds severely, the surface water should be scraped off in time before leveling, otherwise a weak layer will be formed on the surface, affecting the final surface strength and flatness. Timely grinding (milling)： For floors with ultra-high flatness requirements (such as ultra-flat floors), after the laser leveling machine completes the operation and the concrete reaches the initial setting (people step on it and there is a footprint about 3-5mm deep), it will be used. Double disc driving trowel. Perform overall grinding (milling). This step can eliminate the tiny marks left by the laser leveling machine scraper and the unevenness caused by individual aggregates. It is a key step in achieving extremely high flatness. Slit: Expansion joints must be cut in time within the specified time (when the concrete strength reaches 25-30% of the design strength) to avoid irregular cracking that damages the flatness. Maintenance: Use plastic film to fully cover or spray curing agent to provide sufficient moisturizing maintenance to prevent shrinkage cracks and peeling due to rapid water loss on the surface, there by protecting the flatness that has been achieved. Characteristic Concrete laser leveling machine Traditional manual leveling Benchmark Fixed absolute laser plane (precise) Moving channel steel, rulers, or workers' sight lines (prone to error accumulation) Control method Computer real-time calculation, automatic hydraulic adjustment (intelligent, continuous) Human judgment based on experience and manual operation (subjective, intermittent) Flatness Very high, can reach±2mm within 2 meters Even higher Low, usually only reach4-5mm/2m Efficiency Extremely high, 10-20 times that of manual labor Low, depends on the number and skill of workers Artificial Dependency Low, 1 operator and a few assistants High, requires a large number of skilled workers In short, to improve the flatness of the concrete laser leveling machine, it must be recognized that it is a systematic project: Relying on its high-tech "brain" (control system) and "eyes" (laser system) is a prerequisite, but the final effect also depends on a qualified "foundation" (base and formwork), uniform and stable "ingredients" (concrete), standardized "cooking techniques" (operating technology) and proper "post-processing" (polishing and maintenance).Only when every link is done well can the highest standard of flat floor be produced.
