What is the future development trend of concrete laser leveling machine?

    Although the concrete laser leveling machine is a highly precise device, it is not a "fully automatic wonder". The final leveling accuracy (FF/FL value) of it is highly dependent on the perfect coordination of "human-machine-material-method". Often, the machine itself is not faulty, but the ground it produces has unevenness or wave patterns. Here are the four main sources of common errors and their specific solutions. This is a "guide to avoiding pitfalls" derived from countless construction sites. This is the most common but also the most easily overlooked source of error. The laser system serves as the benchmark for the leveling machine. If the benchmark is incorrect, everything will be ruined. Source of error Description of the phenomenon Solution Reference drift of the transmitter Over time, the overall elevation of the entire area has shifted or there has been a large-scale inclination. Root control: The launcher tripod must be set up on a completely stationary base (strictly prohibited from being placed on soil prone to subsidence or on vibrating floor slabs). Root control: The launcher tripod must be set up on a completely stationary base (strictly prohibited from being placed on soil prone to subsidence or on vibrating floor slabs). Laser signal dead zone / interference The machine suddenly started to move erratically, or the leveling head began to shake up and down. Clean up the site: Ensure there is no obstruction (workers moving, pillars) between the transmitter and the receiver. Light shielding reflection: Remove large areas of glass and stainless steel plates at the scene to prevent multi-path laser reflection that could cause false signals. Adjusting the Dead Band: Based on the requirements for flatness, appropriately set the sensitivity (width of the dead band) of the receiver. Strong wind vibration During outdoor construction, strong winds blew the transmitter, causing the base surface to shake up and down. Physical Wind Protection: Build a wind shield around the transmitter, or use a heavy tripod with added weights. 💡 Expert tip: Never allow the power cords of the concrete pump pipe or the vibration rod to come into contact with the frame of the laser emitter! This is the most embarrassing error that can occur on-site. The mechanical condition of the machine directly determines whether it can accurately execute the instructions of the laser system. Question: If there is a significant difference in tire pressure between the left and right wheels, the machine will shake while moving, causing the leveling head to sway left and right and resulting in wave patterns. Solution: Before construction, the tire pressure of all four wheels must be measured to ensure they are exactly the same. Question: The laser caused the scraper to rise, but the hydraulic cylinder responded half a second later, resulting in a "pit" on the ground. Solution: Check if the hydraulic oil temperature is too high and if the solenoid valve is clogged. Problem: The bottom of the scraper is worn unevenly, resulting in scratches or stripes on the polished surface. Solution: Daily inspect the wear plate at the bottom of the scraper. Replace it immediately if it is severely worn. This is the factor that the machine "cannot control" but is the most affected one. The inconsistency in slump (cohesion) is the number one killer of flatness. Too dry (<100mm): The machine cannot scrape, or the leveling head is "pushed up" by the counterforce, resulting in an overly high ground elevation. Too dry (<100mm): The machine cannot scrape, or the leveling head is "pushed up" by the counterforce, resulting in an overly high ground elevation. Solution: Strict control must be exercised over the material distribution at the concrete mixing station! Designate a dedicated person to test the slump before the tanker unloads the material. Those with Unqualified slumps must be immediately withdrawn or adjusted on-site. The optimal slump for the laser leveling machine is typically 140mm ± 20mm (depending on the model). Question: The interval between the first batch of materials and the second batch is too long, resulting in "cold joints" or hardness differences at the junction. The machine will vibrate when passing through. Solution: Ensure continuous supply of materials and avoid any interruptions. A good machine requires a good operator. The operator's experience determines 30% of the final outcome. Error principle: If the concrete in front of the scraper is piled up too high (for example, more than half the height of the feeding screw), the machine resistance becomes too large, the tires slip or the machine head is lifted. If it is piled up too little, it will result in the pit not being filled. Solution: The operator needs to work in coordination with the general workers to ensure that there is always only 2-3 cm of excess concrete remaining on the scraper during the rolling process. Make more corrections when necessary and avoid excessive adjustments. Solution: The recommended standard overlap width is usually between 15cm and 30cm, and the marking lines should be used to assist with walking. Solution: The recommended standard overlap width is usually between 15cm and 30cm, and the marking lines should be used to assist with walking. Question: It's like driving over a speed bump. If you go too fast, the suspension system doesn't have enough time to react. Solution: Maintain a constant speed. It is generally recommended to keep the speed within the range of 3 – 5 meters per minute, allowing sufficient reaction time for the hydraulic system. Check 1 (Test): Before starting each day's work, calibrate the laser transmitter and check the tire pressure. Check 2 (Control): Strictly control the slump of the first batch of concrete, and set the standard for the day. Check 3 (and): At a distance of 2 meters behind the leveling machine, arrange workers to hold a 3-meter scraper to perform fine adjustment (remember: it's fine adjustment, not re-scraping), to eliminate any minor defects that may remain at the turning points or seams of the machine.   Note: The parameters provided in this document are for reference only and are not mandatory.

1. Laser transmitter and receiver The concrete laser leveling machine uses a laser transmitter and a receiver. The laser beam emitted by the laser transmitter is received by the receiver and converted into an electrical signal. These electrical signals are used to control the movement of the leveling and the smoothness of the concrete surface. 2. Positioning and calibration of laser beam The positioning and calibration of the laser beam is one of the important working principles of the concrete laser leveling. Before construction, the laser beam needs to be positioned and calibrated by the leveling to ensure that the laser beam can be accurately projected onto the concrete surface. This is usually achieved by setting a reference point before construction. The leveling machine receives the signal of the reference point through the receiver and aligns the laser beam with the reference point to achieve positioning and calibration of the laser beam. 3. Work flow of leveling machine The workflow of the concrete laser leveling machine includes the following steps: ★1. Preparation before construction: Before construction, the leveling machine needs to be debugged and calibrated to ensure the normal operation of the equipment. At the same time, the concrete surface also needs to be cleaned and prepared to ensure the construction effect. ★2. Laser beam positioning and calibration: By setting the reference point, the leveler receiver receives the signal of the reference point and aligns the laser beam with the reference point, thereby achieving the positioning and calibration of the laser beam. ★3. Concrete laying: After the laser beam positioning and calibration is completed, the concrete laying work can be carried out. The leveling machine can level and trim the surface of mixed soil according to preset flatness and height parameters. ★4. Surface treatment: After the concrete laying is completed, the leveling machine can further process the concrete surface, such as compaction, smoothing, lightening, etc., to ensure the flatness and smoothness of the surface. ★5. Construction completed: After completing the surface treatment, the leveler can stop working and wait for the concrete to solidify. After the concrete has solidified, subsequent construction work can be carried out. 4.

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.
