Laser leveling machine manufacturers reveal to you the root cause of the equipment hopper being unable to close

    Standardize the daily cleaning and regular maintenance of concrete laser leveling machines to ensure that the equipment is in the best technical condition, prevent abnormal wear and failure, improve equipment utilization and economic benefits, and eliminate potential safety hazards. This program is applicable to all operators, maintenance personnel and equipment managers of concrete laser leveling machines. All cleaning and maintenance work must be carried out after the equipment has completely stopped, the engine has been turned off, and the key has been removed. For the operation of hydraulic and electrical systems, it must be confirmed that the system has been completely depressinized. Wear appropriate personal protective equipment, including but not limited to: protective gloves, safety glasses, and anti-crush work shoes. When working under the equipment, it is essential to use safety brackets or jack brackets for reliable support to prevent the equipment from accidentally falling. A warning sign reading "Under maintenance, Do not start" must be placed on site. Objective: Remove the dirt accumulated on the day, inspect the basic condition, and get ready for the next day's work. Serial number Assignment project Standards and Requirements 1 Preliminary cleaning of the entire machine Use high-pressure water guns or manual tools (scrapers, brushes) to remove large blocks of concrete and mud adhering to the chassis, scrapers, vibrators, walking tracks/wheels. Note: Avoid directly flushing the engine air intake, radiator, bearing housing, electrical interfaces and laser receiver with high-pressure water. 2 Fine cleaning of key areas Under the scraper and vibrator: They must be thoroughly cleaned to ensure there is no hard concrete buildup, guaranteeing no resistance during the next start-up. • Laser receiver sensor: Wipe it clean with a soft cloth to ensure there is no dirt blocking it. • Piston rods of each cylinder: Before retracting, wipe their surfaces clean with a soft cloth to prevent cement particles from scratching the seals. 3 Cleaning of the walking system • Crawler type: Clean the crushed stones and mud blocks in the crawler chain links, drive wheels and guide wheels. • Wheel type: Remove debris from the tire treads. 4 Post-operation inspection • Leakage inspection: Visually inspect the hydraulic pipelines, joints, and cylinders for any oil leakage. • Loosening check: Inspect whether the main connecting bolts (such as scraper and vibrator mounting seats) are loose. • Visual inspection: Check for obvious cracks or deformations in structural components. 5 Park Park the equipment on a flat and solid ground. Retract the cylinder to lift the scraper off the ground. Disconnect the power supply (if any). Objective: Conduct systematic inspection, adjustment, lubrication and component replacement to fundamentally maintain equipment performance. Note: The following cycles are general recommendations. Please be sure to refer to the final regulations in the equipment manufacturer's manual. The maintenance cycle should be shortened under harsh working conditions. Maintenance cycle Maintenance items Standards and Requirements 50 working hours per week 1. Lubrication and maintenance Apply the specified lithium-based grease to all lubrication nozzles (grease nozzles) until the new grease is squeezed out from the seal. Key points include: All bearing housings (vibrator bearings, walking wheel bearings). All pins and joint joints (lifting connecting rods, adjusting mechanisms). • Clean up any spilled old butter and keep it clean. 2. Fastening inspection Use a torque wrench to check and tighten the key bolt connections according to the specified torque value. 3.

Laser system calibration Check the consistency between the laser emitter and the control system of the leveling machine, and calibrate it if necessary. Every six months / 1,000 working hours 1. Replacement of hydraulic oil and filter elements Completely replace all the hydraulic oil. All hydraulic filter elements (suction oil filter, return oil filter, pressure oil filter) should be replaced simultaneously. • Clean the interior of the hydraulic oil tank (a special cleaner and dough can be used for adhesion). 2. Engine maintenance • Replace the engine oil, oil filter, fuel filter and air filter. Check and adjust the tension of the fan belt. 3. Inspection of the walking system Check the wear of the tracks/tires and adjust the tension of the tracks. • Check the drive motor and reducer. 4. In-depth inspection Check the installation and tightness of major components such as hydraulic pumps, motors, and multi-way valves. Check whether there are any scratches or rust on the surface of the piston rods of each cylinder and whether the seals are intact. 2,000 working hours per year Comprehensive and systematic inspection and calibration It is recommended to be carried out by professional service engineers, including: Check whether the pressure and flow rate of the hydraulic system meet the standards. • Conduct a comprehensive inspection of the electrical control system and sensors. • Conduct flaw detection on structural components (if necessary). Thorough cleaning: Wash thoroughly according to the daily procedure and dry completely. Rust prevention treatment: Apply rust prevention grease to all exposed metal surfaces (such as cylinder piston rods, guide rails, bolt threads). Oil protection: Add hydraulic oil to the upper limit and carry out anti-rust treatment on the engine crankcase and fuel system. Tires/Tracks: Lift the equipment up to lift the tires/tracks off the ground. Battery: Disconnect the negative terminal of the battery, take it out and store it in a dry and well-ventilated place, and charge it regularly. Parking environment: Store in a dry and well-ventilated indoor area and cover with tarpaulin to prevent dust. After each cleaning and maintenance is completed, the date, working hours, maintenance content, replaced parts and the person who performed the task must be recorded in detail on the "Equipment Maintenance Record Form". The operator is responsible for daily cleaning and inspection, while the mechanic or equipment administrator is responsible for regular deep maintenance. Managers should regularly check the completeness and authenticity of maintenance records. Establishing and strictly implementing this standard operating procedure can transform the management of concrete laser leveling machines from "passive maintenance" to "active prevention", which is the core link to achieve refined equipment management and cost reduction and efficiency improvement.

The laser leveling machine can bring us many advantages when it is used. I believe that all the friends who have used it should have realized it. Although everyone is very comfortable when operating the leveling machine, it is necessary to talk about the laser leveling machine. The components, then many friends are not clear, it seems that everyone is not careful enough about the leveling machine, the following article will lead everyone to learn more about the components of the laser leveling machine. Vanse boomed laser leveling machine Components of the laser leveler: 1. Steering system: It consists of steering wheel, steering gear, steering knuckle, steering knuckle arm, tie rod and straight rod. The function is steering. Battery: The function of the battery is to supply power to the starter, and to supply power to the engine ignition system and other consumers during engine start or low speed operation. When the engine is running at high speed, the generator generates enough power and the battery can store excess power. Hydraulic brake structure: The hydraulic brake device consists of a brake pedal, a master cylinder, a sub-pump, a drum (wheel) brake and a fuel pipe.   2. Motor: The motor is the power unit of the laser leveling machine. Its main function is to generate drive torque as a power source for electrical appliances or various machines. Its main function is to use mechanical energy to convert into electric energy. At present, it is more common to use heat energy, water energy, etc. to drive the generator rotor to generate electricity. 3. Transmission: It is composed of transmission case, transmission cover, first shaft, second shaft, intermediate shaft, reverse shaft, gear, bearing, operating mechanism, etc. It is used for variable speed and variable output torque of laser leveling machine. 4, leaf springs and shock absorbers: the role of leaf springs is to maintain a flexible connection between the frame and the body and the wheel or axle. The function of the shock absorber is to moderate the vibration when the laser leveler is subjected to shock. 5. Transmission system: It is mainly composed of transmission, universal joint, transmission shaft and drive axle. 6, driving system: consists of the frame, axle, suspension and wheels. Its basic function is to support the quality of the whole car and to ensure the driving of the laser leveler. 7. Starter: Its function is to convert electrical energy into mechanical energy, drive the crankshaft to rotate, and start the engine. If the continuous starting time is too long, it will cause a large discharge of the battery and the starter coil will overheat and smoke, which will easily damage the laser leveling machine.

​Laser leveling machine is developed according to the increasing demand of modern industrial plant, large shopping mall, warehouse and other large area cement concrete ground for ground quality, such as strength, flatness, levelness, etc. It has the characteristics of good performance and high efficiency. A. Preparations: (1) After the basic treatment, the laser paver is debugged and fixed reference level is drawn according to the original level; non-woven fabrics and side dies are laid, laser transmitters are erected, and ground elevation is introduced into laser leveller according to the original level. (2) The concrete is transported by commercial concrete. The commercial concrete is transported to the entrance and exit of the garage by tank truck, and then transported to the construction site by three-wheel dumper truck. (3) The elevation of the ground floor is checked by hand-held laser receiver, and the elevation is introduced into the laser paver to adjust the reference point (±0.00) on the leveller. B. Concrete Paving: (1) After the formwork is supported, the warehouse should be cleaned one day in advance and soaked with water before pouring concrete. When approaching pouring, drain open water, sweep cement slurry or interface agent. Obvious water accumulation is strictly prohibited at this time. If so, the concrete can be paved only if it is removed resolutely. (2) After the concrete is laid down, it is preliminarily flattened. The flattened height should be 3cm thicker than the elevation. Then it is leveled with a laser paver. The corners which can not be leveled can be leveled by gasoline leveling ruler or manual method. (3) For concrete mixer can not drive to the site area, but also use tractors to transport concrete. After the completion of the pouring, the floor lighting construction will begin when the concrete is initially solidified. (4) In construction, the laser signal received by the laser paver receiver (10 times per second ) automatically adjusts the elevation in real time to ensure that the construction elevation is always in the set standard. Because the laser transmitter is fixed after being set up, it can ensure that the construction of large area of the ground does not produce cumulative errors. (5) During the construction, the operator uses a hand-held laser receiver to inspect the ground after the construction of the machine to ensure that the smoothness error is within the controllable range again. *Notice: It is necessary to ensure that all parts of the laser leveling machine are connected perfectly, without any loosening, so as to prevent problems in the operation process. Add enough lubricating oil to laser leveling machine in advance to improve the flexibility of controller, so as to improve work efficiency. The surface insulation of cable must be complete, and the slightly damaged parts should be treated with caution until they are all in good condition. This can not only ensure the safety of construction personnel, but also the safety of passers-by. After turning on the power supply, it is necessary to check the direction of the motor rotation. If there is a mistake, it is necessary to change the line immediately in order to avoid greater problems in working hours. Laser leveling machine operators should undergo professional training, such as in the operation process, they can not tilt, can not grasp too tight and other elements should be mastered well, in order to avoid accidents accidentally. Laser leveling machine in the construction process, needs density of soil, can repeat consolidation, don't move back and forth, so even if the result is the same, it will spend more energy on moving, not economical.
