Daily maintenance of small drilling rig compact rotary excavator drilling rig Fang Fa: Using a lifting device to lift the device is also called“Reverse active connector”and“destructive force device”. It is an important part of small drilling rig manufacturers in lifting drill pipes and tools. The structure and performance of the main hoisting wire rope and the inductor are connected together 2. a small type drilling rig, and the drill pipe at the top is on top. When the main hoisting wire rope shrinks, the rotary drill pipe and drill bit can be improved. When the power head rotates, the drill bit is drilling the ground and throwing earth. As the drill pipe force changes. After its own rotation, the transmission of changing forces caused by the rotation of the wire rope due to the rotation of the drill rod is eliminated, which avoids the appearance of the wire rope from changing. If kinks, curls, cracks and other conditions occur, big things will happen. Therefore, the lifting device under high tension conditions should have good tensile strength and sensitive rotation ability. Precautions when using inductors in 3.1Before using the inductor or using it for a long time, the micro excavator drilling rig should be filled with grease. After injection, the joint rolls and rolls without jamming.2Loosen the grease, remove the oil plug and oil (grease gun, etc.) with the grease nipple, slowly inject grease until the joint comes out from the bottom and tighten the screw plug. Overflow, foreign matter into the oil circuit.
3, will pin end, jack and lift both ends,UThe groove fitting is inserted into the lug hole of the drill pipe and passes through the bottom pin shaft installation, flat washer, spring ring and stop pin. Connecting the main winding wire rope ringUShaped slots, holes and pins, mounting flat washers, spring rings and pins.4Before installing the drill pipe, it is necessary to check the lower joint of the traction device.UThe straightness of the shaped groove so that the guide can move up and down along the straight line and the ground. Slowly raise the main hoist until the drill pipe is installed. Routine maintenance and protection of 4. induction machines1Before replacing the old and new grease, lubricate all shifts (approx.12Hours) to the lubricator, lubricate and rotate well until the new grease overflows. To check for stagnation of the drum, turn the joint by hand.2Check whether there is oil overflow. If the oil is mixed with sand, mud and other foreign matter, it means that the existing seal is damaged and must be replaced or repaired in time.3. Check whether the exterior of the elevator is intact, whether the pins at both ends are firmly connected, and whether the grease leakage is abnormal.4. Replace other grease marks over time. If it is not used for a long time, please fill the grease drill in a small rotary excavator.
