How does the laser scanning system of the laser leveling machine achieve positioning and reflection?

    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.    

  The laser leveling machine equipment produced by our manufacturer has good precision. It can perform leveling work efficiently and accurately under any conditions, saving a lot of manual maintenance operations and truly realizing the advantages of intelligent performance. If users want to truly play the role of the laser leveling machine, they can only better apply the equipment by understanding its operating points. So, what is the importance of adjusting the relaxation angle during the construction of the laser leveling machine? The molds used in the field of precision stamping processing are equipped with guide pins to correct the length of the material fed into the mold each time to ensure the accuracy of the stamping production. If this correction is to be truly realized, the laser leveling machine must be equipped with a relaxation device to achieve it. After the tip of the mold guide pin enters the stamping material, the laser leveling machine clamp is in a relaxed state. At this time, the guide pin can correct the error in time, and this relaxation time is the relaxation angle of the laser leveling machine. When professional technicians install laser levelers for customers to debug and test molds, they will adjust the leveling height, leveling angle and relaxation angle of the leveler according to the molds used by the customers for actual mold testing. After single punching and mold testing, continuous punching will be performed to ensure that the continuous punching reaches the predetermined accuracy. At the same time, they will provide detailed training to the operators of the punch laser leveler production line, teaching them how to use, debug, maintain and repair the laser leveler equipment on a daily basis. However, in actual use, many operators use laser levelers for the first time. After replacing the new mold for the punch, they often only remember to adjust the height of the laser leveler (because after changing the mold, the mold height is different, and the leveling height needs to change, which is very intuitive), but ignore the adjustment of the relaxation angle of the leveler. At this time, the leveling will be inaccurate. The operator is not familiar with the leveler and often can't think of the problem. At this time, the operator will complain that the leveler is not good and can only be used for one mold. In fact, this is because the relaxation angle of the laser leveler has not been adjusted correctly, resulting in inaccurate leveling. The laser leveling machine manufacturer told us that the adjustment of the leveling angle of the laser leveling machine after changing the mold is an indispensable link. The adjustment standard is that when the mold guide pin enters the material hole and relaxes, the guide pin is not out of the material pinhole when the mold rises. The precision laser leveling machine clamps the material as the basic principle, so as to truly ensure the high-precision punching production. The equipment provided by the laser leveling machine manufacturer has a more advanced function, can perform leveling operations efficiently, and our price is reasonable and the product quality is good.

– Prevent entrapment: When the metal trowel is rotating at high speed, the operator should be careful to avoid clothing, hair, fingers, etc. from getting close to the rotating trowel. Wear work clothes, tie the cuffs and hems tightly, and wear a safety helmet and protective gloves. For example, before starting the trowel, be sure to carefully check the surrounding environment to ensure that there are no debris that may be involved. – Prevent fragments from splashing: If the metal trowel is cracked or broken, the fragments may splash and injure people. Therefore, check the integrity of the trowel regularly. If there are signs of cracks or damage, stop using it and replace it immediately. At the same time, during use, maintain an appropriate safety distance and avoid standing in the direction where you may be hit by fragments. – Proper installation: When installing the metal trowel, ensure that it is firmly installed. According to the instruction manual of the trowel, use appropriate tools to install the trowel on the corresponding shaft and tighten the screws. Insecure installation may cause the trowel to loosen or fall off during operation, which will not only affect work efficiency but also cause safety accidents. – Control operating parameters: – Speed ​​control: Operate strictly according to the rated speed of the trowel machine, and do not increase the speed at will. Too high a speed will increase the centrifugal force of the trowel blade, which may cause the trowel blade to deform and damage, and will also increase wear. For example, for most concrete trowel operations, the trowel blade speed is generally controlled at around 70-150 revolutions per minute. – Pressure control: Reasonably control the pressure of the trowel blade on the ground. If the pressure is too high, the friction between the trowel blade and the ground will be too large, which may easily cause the trowel blade to wear too quickly, and may also cause scratches or unevenness on the ground. Generally, the pressure is adjusted according to the hardness of the ground and the trowel stage (rough grinding or fine grinding). The pressure should be appropriately reduced in the fine grinding stage. – Avoid idling and excessive friction: Try to reduce the idling time of the trowel blade. When idling, the trowel blade does not contact the ground for effective operation, but its own rotation will cause wear. At the same time, during use, avoid direct friction between the trowel and hard objects such as metal, such as avoiding operation on metal structures without concrete and other ground materials to prevent damage to the trowel blade. – Timely cleaning: After each use, clean the concrete residue, dust and other debris on the trowel in time. If these debris are not cleaned in time, the friction between the trowel and the ground will increase the wear rate during the next use. You can use a brush or a high-pressure air gun to clean it. – Check the wear condition: Check the wear degree of the trowel regularly. Observe whether the edge of the trowel becomes blunt, has a gap or a large area of ​​wear. If the edge wear exceeds a certain limit (such as wear exceeding 2-3 mm), the trowel needs to be replaced. At the same time, check the flatness of the trowel. If deformation occurs, it should be replaced or repaired in time. – Prevent corrosion: If used in an environment with chemical substances (such as acid, alkali, etc.), the trowel should be cleaned in time to prevent chemical substances from corroding the metal trowel. In addition, when storing in a humid environment, anti-rust measures should be taken, such as applying anti-rust oil.
