Maintenance and maintenance methods of hydraulic tunnel drilling rig for coal mine: 1. Hydraulic oil with specified label should be used, and the filter screen of air filter must be used to add hydraulic oil. 2. Always observe the fuel tank level and oil quality during use. If it is insufficient, add oil in time. If the oil is unqualified, drain the oil and clean the fuel tank. Then add clean special oil through the air filter screen. Clean the hydraulic system completely. 3, often check and clean the jack and the screw rod, and coated with butter, the surface of the fuselage guide should be often added with lubricating oil. 4. Always flush the gap between the chuck and the gripper slips with high-pressure water to remove rock powder. 5. Inspection
Maintenance and maintenance method of hydraulic tunnel drilling rig for coal mine:
1. The hydraulic oil with the specified label should be used, and the hydraulic oil must be filtered with the filter screen of the air filter.
2. Always observe the fuel tank level and oil quality during use. If it is insufficient, add oil in time. If the oil is unqualified, drain the oil and clean the fuel tank. Then add clean special oil through the air filter screen. Clean the hydraulic system completely.
3, often check and clean the jack and the screw rod, and coated with butter, the surface of the fuselage guide should be often added with lubricating oil.
4. Always flush the gap between the chuck and the gripper slips with high-pressure water to remove rock powder.
5. Check whether there is any leakage in the oil pipe joint.
6. Check whether the claw movement on the gripper slide is flexible and whether the bearing rotates flexibly. Regularly lubricate the bearing through the grease nozzle in front of the gripper and coat the slide with butter.
7. To ensure the amount of oil in the gearbox, change the oil every three months.
8. Lubricate the thrust bearing in the transmission shaft with oil in each shift. The exposed hexagonal casing shaft is often dusted and kept clean, and makes it slide freely in the box.
9, to ensure that the water will be tight and no water leakage at each interface, if there is water leakage, the sealing ring should be replaced in time.
10, often check the hydraulic parts and seals, if there is leakage, should be handled in time, if necessary, should be replaced.
11. During the drilling process, check the temperature rise of each rotating part and oil tank at any time. Usually, when the oil temperature is below 10 ℃, no-load operation shall be carried out to increase the oil temperature. The oil temperature in the oil tank shall not exceed 55 ℃, otherwise the cooler shall be used to cool down in time, and the cooling water pressure shall not exceed 1.0Mpa.
12, according to the operation of the drilling rig and sound, timely judge the drill bit wear condition, wear damage should be replaced in a timely manner.
13, must be regularly carried out major, medium and minor repairs and strengthen the usual maintenance and maintenance. Generally, it is stipulated that overhaul shall be conducted once every six months, medium repair shall be conducted once every three months, and minor repair shall be conducted once every shift.
14, often check the deflection of the track. First, clean the crawler, place a wooden wedge on the back and top of the driven wheel, and then start the walking crawler to squeeze the wooden wedge, so that the grounded side of the crawler is tensioned, and the loose part of the upper part is deflated, and the deflection can be measured with a ruler. The normal deflection is generally 8~15mm.
