How to perform daily maintenance on the concrete laser leveling machine to ensure its long-term stable operation?

1. Inspection before work

- Appearance inspection:

- Carefully check whether the appearance of the equipment has signs of damage, such as whether the fuselage has cracks or deformation, especially whether the shell of the laser receiver and transmitter is intact. Because these parts are relatively delicate, damage to the shell may affect their performance.
- Check the condition of the tires (if it is a wheeled leveling machine) or the crawler (if it is a crawler leveling machine), check whether the tires have obvious wear and scratches or whether the air pressure is normal (the tire pressure should generally be kept within a certain range as required by the equipment manual, such as 3-4 atmospheres); whether the crawler has loose or broken links, etc.

- Connection parts inspection:

- Check whether the bolts and nuts at each connection are tightened. Focus on checking the connection between the working parts such as scrapers and spiral feeders and the fuselage, because these parts will generate greater vibration and force during work, and loose bolts may cause parts to fall off or work abnormally. You can use a wrench to properly tighten the bolts at key locations.
- Check whether the connection between the hydraulic and electrical lines is good. Make sure that there is no leakage in the hydraulic lines and there should be no oil stains on the pipe joints; the plugs and sockets of the electrical lines should be tightly connected, and the wires should not be damaged or aged.

2. Precautions during work

- Operation specifications:

- Operate strictly in accordance with the operating manual and avoid sudden acceleration, sudden braking or oversteering. For example, during the movement of the leveler, the speed should be controlled smoothly to avoid sudden changes in speed that cause the machine to vibrate violently, which may damage the internal structure of the machine and the laser calibration system.
- Pay attention to the working status of the equipment, including the sound and temperature of the engine (if it is a fuel type) or the motor (if it is an electric type), as well as the operation of each working part (such as scraper, distributor, vibrator, etc.). If abnormal sounds (such as sharp friction sounds, impact sounds) or working parts shake or stagnate, stop the operation immediately and check the cause.

- Laser system maintenance:

- Make sure the lenses of the laser transmitter and receiver are clean. In the case of a bad working environment (such as dust, mortar splashing, etc.), the lens should be cleaned regularly. You can use a clean, soft, wet cloth to gently wipe the lens surface to avoid scratching the lens.
- Pay attention to the strength and stability of the laser signal. If the laser signal is found to be interrupted or unstable, it may be due to the position of the transmitter or receiver being offset, the battery being low (for portable laser equipment), or being interfered with by the outside world. The position of the equipment should be adjusted in time, the battery should be replaced, or the interference source should be eliminated.

3. Cleaning and maintenance after work

- Cleaning the body:

- After each work, use a high-pressure water gun (be careful not to use too high a pressure to avoid damaging the equipment) or a soft brush, wet cloth and other tools to remove concrete residues, dust and other debris from the surface of the equipment. For hardened concrete that is difficult to remove, a special cleaning agent can be used for cleaning.
- Focus on cleaning working parts, such as scrapers, blades of spiral feeders, etc., to ensure that there is no concrete residue on these parts to avoid affecting the accuracy and efficiency of the next work. At the same time, clean the bottom of the body to prevent the residual concrete from solidifying during the parking process of the equipment, affecting the normal placement of the equipment and the next start-up.

- Lubrication and maintenance:

- Lubricate key parts regularly according to the frequency of use and working intensity of the equipment. For example, the bearings, joints, chains (if any), etc. of the equipment should use appropriate lubricants (such as lithium-based grease). Generally, a simple lubrication check is performed every 8-10 working hours, and a comprehensive lubrication is performed every 50-100 working hours.
- For the hydraulic system, check the oil level and oil quality of the hydraulic oil. The oil level should be kept within the specified scale range of the hydraulic oil tank. If the oil level is too low, a qualified hydraulic oil of the same model should be added; at the same time, observe the color and transparency of the hydraulic oil. If the hydraulic oil is found to be black, turbid or has a peculiar smell, it may be that the hydraulic oil is contaminated or aged. The hydraulic oil should be replaced in time. It is generally recommended to replace the hydraulic oil every 1000-1500 hours.

- Storage environment:

- Store the equipment in a dry and well-ventilated indoor environment to prevent the equipment from getting damp and rusting. If it can only be stored outdoors, the equipment should be covered with a waterproof cloth to prevent rain, dew, etc. from corroding the equipment.
- During the storage period, the scraper, spreader and other working parts of the equipment can be raised to make the tires or tracks a certain distance from the ground (such as using blocks to raise them). This can reduce the pressure of the equipment's own weight on the tires, tracks and chassis and extend the service life of these parts. At the same time, disconnect the power supply of the equipment (if it is an electric equipment) or close the fuel valve (if it is a fuel equipment), and remove the battery (if it is easy to remove) to prevent battery leakage or fuel leakage.
