What are the precautions for the maintenance and upkeep of the roadway repair machine used in coal mines（haoyun）

The editor of Shandong Haoyun Heavy Industry Machinery Co., Ltd. will discuss the following precautions for the maintenance and upkeep of roadway repair machines used in coal mines.

The maintenance and upkeep of coal mine tunnel repair machines are key to ensuring their long-term stable operation, improving operational efficiency, and extending their service life. Here are some maintenance precautions:

1. Regular inspection and cleaning: Haoyun Heavy Industry regularly inspects and repairs various components of the machine, including the walking mechanism, hydraulic system, electrical system, support installation device, etc., to ensure that there is no damage, wear or leakage. At the same time, keep the machine clean, especially clean the coal slag and dust on the walking tracks and working arms, to prevent foreign objects from entering the interior of the machine and causing malfunctions.
2. Maintenance of hydraulic system: The hydraulic system is a critical part of the repair machine and requires special attention to maintenance. Regularly check the cleanliness and oil level of hydraulic oil, replace hydraulic oil and filters in a timely manner to maintain the normal operation of the hydraulic system. At the same time, check the sealing of hydraulic pipelines and joints to prevent hydraulic oil leakage.
3. Inspection of electrical system: Check the insulation and conductivity of the electrical system to ensure that the cables and joints are not damaged or corroded. Regularly inspect the functionality of the electrical control system, including sensors, controllers, and actuators, to ensure their accuracy and reliability.
4. Lubrication and fastening: Regularly lubricate the moving parts of the machine, such as bearings, gears, chains, etc., to reduce wear and friction. At the same time, check and tighten all screws and connectors of the machine to prevent malfunctions caused by looseness.
5. Spare parts management: Establish spare parts inventory to ensure timely replacement of critical components. There should be sufficient spare parts reserves for vulnerable parts such as cutting tools, buckets, hydraulic seals, etc. to cope with sudden failures.
6. Operator training: Regularly train operators, including not only the operation methods of the machine, but also basic maintenance knowledge, so that operators can identify and handle common faults and reduce downtime.
7. Safety inspection: Haoyun Heavy Industry conducts regular safety inspections, including emergency stop devices, safety protection devices, gas monitoring systems, etc., to ensure the safety of operators in any situation.
8. Records and Reports: Establish detailed maintenance records, including maintenance dates, maintenance items, replacement parts, abnormal situations, etc., to provide a basis for long-term management and fault diagnosis of the machine.

By implementing the above precautions, the service life of coal mine tunnel repair machines can be effectively extended, the failure rate can be reduced, and the operational efficiency and safety can be improved.
