The Cold Wave Is Coming! If The Laser Leveling Machine Is Not Used For A Long Time, You Need To Pay Attention To 10 Maintenance Tips

  The construction process of concrete pavement with double-layer steel mesh differs from that of single-layer steel mesh in the following aspects: – Single-layer steel mesh: – Steel bar processing mainly involves straightening, cutting, bending, etc. according to design requirements. After the processed steel bars are transported to the construction site, they are laid directly on the base. – Usually, the steel mesh is placed in the designated position by manual or small machinery, and fixed with iron wire or steel bar horse stool to ensure that there is a certain protective layer thickness between the steel mesh and the base, generally 3-5cm. – Double-layer steel mesh: – In addition to basic steel bar processing, for double-layer steel mesh, supporting steel bars or horse stool bars need to be set between the upper and lower steel meshes to ensure that the spacing between the two layers of steel mesh meets the design requirements, generally about 15-30cm. – First lay the lower steel mesh, and then install the upper steel mesh after fixing it. During the process, the position and spacing of the two layers of steel mesh must be strictly controlled to ensure that they do not shift during the concrete pouring process. – Single-layer steel mesh: – The installation of the formwork is mainly to ensure that its position is accurate and firm, and it can withstand the lateral pressure during concrete pouring. The height of the formwork is generally consistent with the design thickness of the concrete pavement. – Double-layer steel mesh: – Due to the existence of double-layer steel mesh, the installation of the formwork requires higher precision. When installing the formwork, it is necessary to consider the position of the steel mesh and the thickness of the protective layer to ensure that the spacing between the formwork and the steel mesh is uniform, and to prevent the formwork from squeezing the steel mesh and causing its position deviation. – Single-layer steel mesh: – When pouring concrete, the concrete can be directly poured into the formwork, and the inserted vibrator and the flat vibrator can be used to vibrate to make the concrete dense. During the vibration process, be careful to avoid the vibrator rod directly touching the steel mesh to avoid displacement of the steel mesh. – Double-layer steel mesh: – When pouring concrete, in order to avoid the upper steel mesh displacement caused by the impact of concrete falling, a more reasonable pouring method needs to be adopted, such as evenly spreading the concrete along one side of the formwork, allowing the concrete to slowly flow to the other side, or using a layered pouring method. – When vibrating, in addition to using an insert vibrator and a flat vibrator, for the concrete between the double-layer steel mesh, it may be necessary to use a small vibrating rod or vibrating sheet for auxiliary vibration to ensure that the concrete can be fully compacted between the two layers of steel mesh. At the same time, pay more attention to the operation of the vibrating rod to avoid touching the steel mesh and causing it to deform. – Single-layer steel mesh: – After the concrete is vibrated, use a scraper to flatten the surface, and then perform surface treatment procedures such as smoothing, and finally cover with a curing film or sprinkle water for maintenance to keep the concrete surface moist and prevent the surface from losing water and cracking. – Double-layer steel mesh: – During surface treatment, due to the restraining effect of the double-layer steel mesh on the concrete surface, more care should be taken during operations such as polishing to avoid uneven surfaces caused by the influence of the steel mesh. – During the curing process, it is necessary to ensure that the curing measures can fully cure both the interior and surface of the concrete, because the double-layer steel mesh will affect the migration and heat dissipation of the moisture inside the concrete to a certain extent, so the curing time may need to be appropriately extended, generally not less than 7 days.     CONCRETE LASER LEVELING MACHINE POWER TROWEL TRACKED MINI DUMPER AMOUR JOINT LIGHT TOWER STEEL FIBER  

As a brand-new floor construction equipment, the laser leveling/ leveling machine has been widely concerned by the industry due to its excellent construction efficiency and construction accuracy once it has entered the market, and has been more and more used in warehouses, basements, parking lots, Large-area concrete floors such as industrial plants are under construction. Like other construction machinery, the laser leveling/ leveling machine is also a whole composed of many parts, and the construction environment is relatively complicated, so it is easier to wear than the parts of general machinery during long-term work. In order to prolong the effective life of the laser leveling/ leveling machine, the following is a brief introduction to the main components of its components and the skills of use and maintenance. —-THE CORE COMPONENTS AND FUNCTIONS OF LASER LEVELING/ leveling MACHINE— ➤Drive Train: mainly composed of transmission, universal joint, drive shaft and drive axle; ➤Driving System: composed of frame/axle/suspension/wheels, etc. The function is to support the quality of the whole vehicle and ensure the driving of the laser leveling machine; ➤Steering system: composed of steering wheel, steering gear, steering knuckle, steering knuckle arm, tie rod, straight tie rod, etc., the function is steering; ➤Hydraulic brake: The hydraulic brake device is composed of brake pedal, brake pump, wheel cylinder, drum brake and oil pipe and other parts; ➤Transmission: It is composed of transmission housing, transmission cover, first shaft, second shaft, intermediate shaft, reverse gear shaft, gears, bearings, operating mechanism and other parts, used for changing speed and output torque of laser leveling machine; ➤Leaf Spring and Shock Absorber: The role of the leaf spring is to maintain an elastic connection between the frame and body and the wheels or axles.

Reasonable use and regular maintenance of various parts are effective ways to prolong the service life of the laser leveling machine and improve the economic efficiency of the operation. It is suggested that before using the leveling machine, one should be fully familiar with the composition and function of each component of the machine, master the correct operation method, and strengthen daily maintenance and maintenance.

  The following common problems and solutions may be encountered by the laser leveler during construction: – Problem description: During construction, the laser leveler may suddenly lose the laser signal. This may be due to the laser transmitter being blocked, such as the surrounding building materials piled up, the construction workers walking and accidentally blocking the signal transmission path, or the bad weather (such as dense fog, heavy rain, etc.) affecting the propagation of the laser signal. – Solution: First, check whether there are obstacles between the laser transmitter and the receiver. If there are, remove the obstacles to ensure that the signal transmission path is unobstructed. For signal loss caused by weather reasons, in dense fog or heavy rain, construction can be suspended and wait for the weather to improve. If construction cannot be suspended, consider adjusting the position and height of the laser transmitter to minimize the impact of weather on the signal, and at the same time strengthen the sensitivity setting of the signal receiving device (if the device has this function). – Problem description: The laser signal is deviated, resulting in an error between the working plane of the leveler and the design plane. This may be because the laser transmitter is not installed firmly and has a slight displacement; or it may be affected by external forces such as vibration and collision during the construction process, causing the transmitter's emission angle to change. – Solution: Make sure the laser transmitter is installed firmly before construction, and calibrate it after installation. During the construction process, check the position and angle of the laser transmitter regularly. If the signal is found to be inaccurate, use professional calibration tools to recalibrate the horizontality and emission angle of the laser transmitter to make it consistent with the benchmark of the design plane. – Problem description: The ground after leveling is partially uneven. This may be due to uneven wear of the scraper of the leveling machine, or the scraper is subject to greater resistance during the work process, causing the scraper to not work properly. For example, there are hard foreign objects on the ground, such as large pieces of stone, steel bars, etc., which will affect the flatness control of the scraper. – Solution: Check the wear of the scraper regularly, and replace the severely worn scraper in time. Before construction, clean up foreign objects on the ground to ensure that the construction site is flat. If the scraper encounters a large resistance during the construction process, stop the machine immediately for inspection, and continue construction after removing foreign objects. In addition, the leveling effect can be improved by adjusting the walking speed of the leveler and the working pressure of the scraper. Generally, a moderate walking speed and uniform scraper pressure can achieve a better leveling effect. – Problem description: Cracks appear on the concrete surface after leveling. This may be due to unreasonable concrete mix ratio, such as excessive cement dosage, excessive water-cement ratio, etc., which causes excessive shrinkage of concrete during solidification; or improper maintenance of concrete after leveling, such as failure to timely moisturize and maintain in a high temperature and dry environment, causing the concrete surface to lose water too quickly and crack. – Solution: Before construction, strictly control the mix ratio of concrete, and reasonably determine parameters such as cement dosage and water-cement ratio according to engineering requirements and environmental conditions. After leveling, timely maintain the concrete, cover the concrete surface with moisturizing materials such as plastic film or wet cloth, especially in hot and dry weather, increase the frequency and time of maintenance to prevent water loss on the concrete surface. – Problem description: The travel mechanism of the leveler cannot work properly, such as unstable travel speed, uncontrolled travel direction or inability to rotate the travel wheel. This may be caused by travel motor failure, loose or broken transmission chain or belt, or damaged bearing of the travel wheel. – Solution: First check whether the travel motor is working properly, check whether the power cord of the motor is well connected, and whether there is a short circuit or open circuit. For the transmission chain or belt, check its tension. If it is loose, adjust the tensioning device in time; if it is found to be broken, replace a new chain or belt. For the bearing of the travel wheel, check whether it is damaged. If it is damaged, replace the bearing in time to ensure that the travel wheel can rotate normally. – Problem description: The scraper cannot be lifted and lowered normally, affecting the leveling operation of the leveler on concrete of different thicknesses. This may be due to a failure in the scraper lift cylinder, such as damage to the cylinder seal causing oil leakage, which prevents the cylinder from providing lifting power normally; or a problem with the lifting control system, such as a control circuit failure or solenoid valve damage. – Solution: Check whether the scraper lift cylinder is leaking oil. If there is oil leakage, replace the cylinder seal. For the lifting control system, check whether the control circuit is well connected and whether there is any damage. If the solenoid valve is damaged, replace a new solenoid valve to ensure that the scraper lift system can work normally.
