1. When there is drilling equipment in the hole, the rotator is not allowed to turn over except for the posture required according to the required procedure.
2. When the rotator is turned over and disassembled the drill pipe, the hydraulic cylinder must keep enough lifting belt stroke arrangement to prevent damage to the external thread of the drill pipe.
3. During the whole process of drilling machine work, attention should be paid to the change of fitness components anytime and anywhere. The temperature rise of rolling bearings, transmission gears, gasoline pumps, oil motors, motors, etc. should not exceed 45 degrees, and the temperature at the oil outlet of the automobile fuel tank should not exceed 60 degrees. Otherwise, it should be shut down for inspection and solved in many ways.
4, check the sewage treatment plant return oil pressure gauge, found that the return oil working pressure exceeds the 0.35 to shut down the replacement or clean the filter device.
5. When the drilling machine is working, pay attention to whether the components of the hydraulic transmission system, rubber hose and tee joint have oil leakage. If there are common faults, they should be properly handled.
6. When the drilling machine is working, in addition to the relative change of the supplied oil working pressure, rotation and pushing rate caused by the change of drilling load, the working pressure of the system software suddenly changes greatly, causing the rotation and pushing rate to change greatly. It should be shut down immediately to find the reason. Solve common faults.
7. When the drilling machine stops working, all operators should place a negative correlation.
8. When withdrawing the drill pipe normally from the drill pipe, the drill pipe must be clamped by a clamp or a rod clamping device. After the rod taking staff must leave the safety address 1 meter away from the drill pipe, the drilling machine driver can be called to start the drilling machine to withdraw the drill pipe according to the safety operation regulations. During the whole process of returning the drill pipe, the staff and the drilling rig driver must cooperate closely, echo each other, concentrate their vitality, and avoid accidents caused by operational errors.
9. When the connecting head of the water identification shaft and the drill pipe is seized and cannot be used as a rod clamping device or a rod clamping device, the drill pipe can be clamped tightly with a pipe wrench, and after the pipe wrench is connected with an extension rod (0.5-1 m) (torque is enlarged), the human resources will loosen the joint of the drill pipe.
10. When the connecting head of the water identification shaft and the drill pipe is killed and cannot be used as a sticking device or a pipe clamp, the drill pipe can be clamped with a pipe clamp. One end of the pipe clamp is only supported by the sound card frame, and the pipe clamp is fixed on the sound card frame with thin wire. After the drill field staff leaves the drill field to the safe address, the drill pipe driver can start the drilling machine to turn over the loose drill pipe to avoid the pipe clamp caused by the pipe clamp due to the pipe clamp.
11. When the inclination angle of the drill pipe exceeds 30 °, the operator shall not face the drill pipe directly to avoid injury caused by the drill pipe sliding down during drilling.
