How to carry out daily maintenance and upkeep of hydraulic anchor rod drilling vehicles used in coal mines（haoyun）

The editor of Shandong Haoyun Heavy Industry Machinery Co., Ltd. will do the following on how to carry out daily maintenance and upkeep of hydraulic anchor rod drilling vehicles used in coal mines.

The daily maintenance methods for hydraulic anchor rod drilling vehicles used in coal mines are as follows:

1、 Hydraulic system maintenance

1. Hydraulic oil management: Use hydraulic oil of the specified grade, regularly check the oil quality and quantity, add it in a timely manner if it is insufficient, and replace it if the oil quality is unqualified. Hydraulic oil needs to be filtered through a filter before being added to the oil tank to ensure its cleanliness.
2. Oil temperature control: During the drilling process, check the temperature rise of the oil tank at any time. The oil temperature should generally be controlled within the range of 30 ℃ -70 ℃. If it exceeds 70 ℃, the machine should be stopped immediately for inspection. When the oil temperature is below 10 ℃, no-load operation is required to increase the oil temperature.
3. System inspection: Haoyun Heavy Industry reminds that the hydraulic system’s pipelines, joints, and other parts should be regularly inspected for oil leakage. If there is any leakage, it should be dealt with in a timely manner. At the same time, check the working status of hydraulic pumps, hydraulic motors, and other components to ensure their normal operation.

2、 Mechanical component maintenance

1. Maintenance of anchor drilling rig: Regularly inspect and clean the jacks and screws of the anchor drilling rig, apply butter, and regularly lubricate the surface of the machine body guide rail. Regularly inspect the oil pipe joints of the drilling rig for any leakage, and replace the sealing ring in a timely manner if there are any problems.
2. Maintenance of crawler: Regularly lubricate and maintain the reducer and other components of the crawler to ensure their good working condition.
3. Maintenance of other components: Regularly inspect the various transmission components of the drilling rig, such as couplings, to ensure that they are firmly connected and operate normally. At the same time, check the bolts, nuts, and other fasteners in each part, and tighten them promptly if they are loose.

3、 Electrical system maintenance

1. Electrical equipment inspection: Haoyun Heavy Industry reminds that the electrical wiring should be regularly checked for looseness, damage, and other phenomena, and whether the voltage, current, and other data are normal. If there are any abnormalities, they should be dealt with promptly.
2. Electrical component maintenance: Regularly clean the dust on the surface of electrical equipment to maintain good heat dissipation. For some vulnerable electrical components, such as contactors, relays, etc., their working status should be checked regularly, and if they are damaged, they should be replaced in a timely manner.

4、 Other maintenance work

1. Equipment cleaning: After each use, the drilling rig should be cleaned, especially key parts such as the radiator and air filter, to prevent dust and other impurities from entering the interior of the equipment.
2. Drill bit replacement: According to the wear and tear of the drill bit, replace it in a timely manner to ensure the quality and efficiency of drilling.
3. Record and Summary: Keep good records of equipment operation and maintenance, summarize and analyze equipment failures and repairs, in order to timely discover problems and hidden dangers in the equipment and take corresponding measures to deal with them
