How does concrete laser leveling technology achieve precise leveling of concrete surfaces?

Can good maintenance habits really prolong the service life of laser levelings? Laser leveling machine is a great helper for leveling machinery in construction, but road builders can always feel that after several years of use, the equipment is far from being as flexible and convenient as before. What is the reason for this? Many users only know the surface and don't know the reason, so they can only procrastinate and procrastinate. When they use it next time, they will regret it. During the use of the laser leveling machine, due to the different working intensity, there may be some small faults after use. At this time, road builders should pay attention to it. After use, it is necessary to properly do some daily maintenance for the machine. This can prolong the service life of the machine equipment. 1.Check the connection and fastening of the parts of the laser leveling machine, whether the connecting bolts are loose or broken, and tighten or replace them if necessary. Check for leaks and eliminate leaks in various parts in time. Pay attention to the quantity of engine oil, fuel, coolant and hydraulic oil, and add new oil to the scale indicated on the oil mark as required. Whether there is proper amount of grease in the centralized lubrication device. 2.Be careful not to work under the maximum load that the machine can bear, and use the machine within your ability. As a laser leveling machine manager, when appointing an operator, the laser leveling machine random data and operation manual should be handed over to the operator, so that they can normally grasp the mechanical properties and operating procedures, and should not arbitrarily hand over the relevant information Buckle it down. 3.It is necessary to ensure the uniform addition and subtraction of the mechanical load as far as possible, so that the machinery is in a relatively gentle load change. Specifically, it is necessary to increase and decrease the throttle more evenly to prevent the engine and working devices from fluctuating greatly. 4.There will be a lot of dust and mud on the laser leveling machine after construction. First, wipe off the dust on the laser leveling machine, and wipe off the dirt and oil stains with tissue paper or cotton cloth. 5.If the laser signal is lost during the construction of the laser leveling machine, the machine needs to be restarted, and the interval should be more than ten seconds. 6.If there are too many stains, you can use a soft cloth to soak in water diluted with a neutral detergent, and then wring it out to clean it. The manufacturer of Wanshi laser leveling machine reminds everyone not to use volatile oil, thinner, gasoline and other chemicals to clean and wipe. . Developing a good habit of operating the laser leveling machine will be of great help to the construction and storage of the laser leveling machine in the future. This will not only improve the work efficiency, but also extend the service life of the machine to a certain extent .

    Before a concrete laser leveling machine that has been idle for a long time is reactivated, a systematic inspection should be carried out to eliminate potential faults (such as component rust, circuit aging, hydraulic jamming, etc.), and the equipment performance should be restored in combination with maintenance to avoid construction quality problems or safety accidents caused by component failure when it is reactivated. The following are the specific inspection and maintenance steps, which are disassembled according to the logic of "appearance → core system → auxiliary components → trial operation" First, inspect thex eterior of the equipment and its easily worn parts, with a focus on checking for physical damage, rust or loosening caused by long-term idleness. This is the foundation for ensuring subsequent system checks. Check whether the frame of the machine body, the leveling scraper and the vibration beam have any deformation or cracks (especially at the welding parts). If there is any slight deformation, it needs to be corrected. If there are cracks, they need to be repaired by welding and ground smooth. Check whether all exposed metal parts (such as bolts, pins, and connecting brackets) are rusted. Rusted areas should be cleaned with a wire brush and then coated with anti-rust oil. Severely rusted parts (such as pins that are stuck) need to be replaced. If it is a wheeled model: Check whether the tire pressure is normal (refer to the standard value in the equipment manual), whether there are cracks, bulges or foreign objects embedded in the tire surface, and whether the valve stems are leaking. If it is a tracked model: Check whether the track plate is excessively worn (the tread depth should be replaced if it is less than 1mm), whether the track tension is appropriate (press the middle section of the track with your hand, and the subsidence should be controlled within 10-15mm), and whether the track pin shaft is stuck (try to rotate it after injecting grease). Check whether the protective covers of the emergency stop button and the operating handle are intact. After the emergency stop button is pressed, it should be able to immediately cut off the power and start normally after resetting. Check whether the warning lights and buzzers are functioning properly (test after power-on), and whether the safety guardrails and anti-slip steps are firm, without any looseness or missing parts.   The core performance of the laser leveling machine machine relies on the power system, hydraulic system and laser control system. It is necessary to check each internal potential hazard one by one to avoid "breaking down" or precision failure when it is put into use. Type Inspection items Maintenance measures Diesel engine 1. Oil level and quality If the engine oil is below the mark, it needs to be replenished (using the same type of engine oil). If it deteriorates (turns black or contains impurities), it should be completely replaced 2. Fuel tank and fuel quality 2. Drain the deteriorated diesel from the fuel tank, clean the tank and then add new diesel. Check if the fuel filter element is clogged (if it is clogged, it needs to be replaced). 3. Coolant level 3. If the coolant is insufficient, it needs to be replenished. (Mix the antifreeze in proportion and avoid adding tap water directly.) 4. Air filter element 4. Remove the air filter element and blow it clean in reverse with compressed air (if the filter element is damaged, it needs to be replaced). 5. Spark plugs/fuel injectors 5. Remove the spark plugs to clean the carbon deposits (if the gap is abnormal, adjust it). The fuel injectors need to be disassembled to check the atomization effect (if the atomization is poor, clean it). Electric motor 1. Motor housing and terminal blocks Clean the dust off the motor casing and check if the terminal blocks are loose or oxidized (oxidation should be sanded with sandpaper). 2. Carbon brushes (if any) When the carbon brush is worn down to one-third, it needs to be replaced to ensure good contact between the carbon brush and the commutator 3. Insulation resistance 3. Measure the insulation resistance with a megohmmeter. A resistance of ≥0.5MΩ is qualified (to avoid leakage). Long-term idleness of the hydraulic system is prone to deterioration of the oil and aging of the sealing parts, which requires special inspection: Hydraulic oil inspection: Open the oil tank cover and observe the color of the oil (normally light yellow. If it turns black or becomes turbid, it needs to be replaced) and the liquid level (it should be within the range of "MIN-MAX" on the oil gauge. If it is insufficient, add the same type of hydraulic oil). If the oil has been idle for more than six months, it is recommended to replace it even if its appearance is normal (the oil will oxidize and become ineffective). Leakage inspection: Check the hydraulic oil pipes, joints, and cylinders (especially the leveling cylinder and traveling cylinder) for any leakage marks. If leakage is found, replace the sealing parts or damaged oil pipes. The joint should be re-tightened according to the manual torque (to avoid over-tightening and damaging the thread). Maintenance of hydraulic components Clean the hydraulic oil filter element (if it is a paper filter element, replace it if it is clogged) to prevent impurities from entering the cylinder and causing wear. Manually push the piston rod of the oil cylinder to check for any jamming (if there is jamming, disassemble the oil cylinder to clean the internal impurities and refill the hydraulic oil). Before starting the equipment, manually rotate the coupling of the hydraulic pump to ensure there is no jamming (to avoid damage to the pump body). The laser system is the "eyes" of the leveling machine. When idle, it is prone to sensor moisture and poor circuit contact, and precise inspection is required Laser emitter Clean the dust off the transmitter lens (wipe it with a soft cloth to avoid scratches), and check the battery power (replace it if insufficient). Power on and test whether the transmitter can emit laser normally (the laser line should be uniform and free of flicker). If the laser is weak or there is no laser at all, check the internal circuit or replace the transmitter. Laser receiver Check whether the receiver probe is damaged or damp (if damp, it needs to be dried), and whether the terminal blocks are loose. Bring the receiver close to the transmitter to test if it can receive signals normally (the indicator light needs to switch normally according to the "high and low positions"). If the signal is unstable, the receiver needs to be calibrated (perform zero point calibration according to the steps in the equipment manual). Control circuit: Check whether the connection lines of the laser control system (from the receiver to the controller, and from the controller to the hydraulic valve) are damaged or aged. The line joints need to be re-plugged and unplugged to ensure good contact (to avoid signal interruption and accuracy deviation).   Apart from the core system, minor issues with auxiliary components may also cause the equipment to fail to operate normally. Each one needs to be confirmed Check the battery level (measure the voltage with a multimeter. For a 12V battery, a voltage of ≥12.4V is normal. If it is insufficient, it needs to be charged; if it has been idle for more than 3 months, it needs to be charged before use to avoid battery depletion and scrapping). Clean the dust inside the distribution box, check whether the fuses are intact (replace the fuses of the same specification if they are blown), and whether the contacts of the relays and contactors are oxidized (if oxidized, sand them with sandpaper). Apply grease to the "lubrication points" marked in the equipment manual (such as walking bearings, scraper connection shafts, and laser receiver rotating shafts) (use lithium-based grease and avoid mixing different types of grease). Each lubrication point should be filled until grease overflows (ensure adequate lubrication). Diesel model: Check whether the fuel pump and fuel line are unobstructed (you can manually pump fuel to remove air), and whether the exhaust pipe is blocked (clean carbon deposits). For electric models: Check if the charger is functioning properly (the indicator light needs to switch normally during charging), and if the cable is damaged (any damage should be repaired with insulating tape to prevent leakage). After completing all inspections and maintenance, it is necessary to conduct a trial run to confirm that the equipment is free of faults and avoid direct construction under load. Start the equipment (engine/motor), let it idle for 5 to 10 minutes, and observe whether the power system is stable (without abnormal noise or vibration) and whether there is any leakage in the hydraulic system. Test each action of the operation handle: walking (forward/backward, turning), lifting and lowering of the leveling scraper, and vibration of the vibrating beam. Ensure that the actions are smooth and without any lag. The laser control system can normally control the leveling height (for example, when the receiver detects the laser offset, the equipment can automatically adjust the height of the scraper). Lay a small amount of concrete (about 10-15cm thick) in an open area, start the equipment for leveling operation, and inspect: Whether the walking speed is uniform (no sudden fast or slow); Whether the vibration frequency of the vibrating beam is normal (no abnormal noise, no obvious honeycomb on the concrete surface); The flatness of the concrete surface after leveling (measured with a 2-meter straightedge, the error should be ≤3mm/2m, meeting the construction standards). During the trial operation, if any abnormality is detected (such as noise, leakage, or accuracy deviation), the machine must be stopped immediately and the fault rechecked.   Refer to the equipment manual: The structure of laser leveling machine machines of different brands may vary. All inspections and maintenance should be based on the parameters in the equipment manual (such as hydraulic oil type, lubrication point position, torque value) to avoid misoperation. Pre-idle record: If conditions permit, a record should be made before the next idle period (such as the time of oil change and the status of components) to facilitate targeted inspection during the next activation. Safety precautions: During inspection and maintenance, the power source must be cut off (remove the key, disconnect the negative terminal of the battery) to prevent accidental start-up. Safety belts must be worn during high-altitude inspections (such as the installation of laser emitters) to prevent falls. Through the above steps, the potential risks of long-term idleness can be comprehensively eliminated, ensuring that the laser leveling machine machine performs stably and meets the precision standards after being reactivated, and avoiding rework or safety accidents caused by equipment failure during construction.
