How To Unlock A Rotary Drilling Rig with A Machine Lock Rod

The unlocking operation of the rotary drilling rig with machine lock rods is a key link to ensure construction safety and efficiency. Incorrect operation may lead to equipment damage or safety accidents. The following are six key steps for unlocking to help standardize the operation process.

1. Check the equipment status: Before unlocking, make sure the drilling rig is parked stably, the power system is operating normally, and all instrument displays are normal. Avoid operating when the equipment is in an unstable state.

2. Adjust the Angle of the drill mast: Adjust the drill mast to a position perpendicular to the ground to ensure that the drill pipe is in a vertical position and reduce lateral stress during unlocking.

3. Release the pressure of the drill pipe: Operate the hydraulic system to slowly release the locking pressure inside the drill pipe. Observe the pressure gauge reading. Wait until the pressure drops to a safe range before proceeding to the next step.

4. Activate the unlocking device: Press the unlocking button on the operation console and observe the movement at the connection of the drill pipe at the same time to ensure that the locking mechanism is completely disengaged from the slot.

5. Test run verification: After unlocking, conduct a short-distance drill pipe lifting test run to check for any jamming or abnormal noise, and confirm that the unlocking is in place.

6. Record operation data: Record the pressure parameters, operation time and other data during unlocking to provide reference for subsequent equipment maintenance and fault detection.

In conclusion, the unlocking of the rotary drilling rig with a machine lock rod should follow the process of "inspection - adjustment - pressure relief - operation - verification - record", and each step is closely linked. Standardized operation not only protects equipment but also enhances construction safety. Operators must strictly follow the procedures to avoid problems caused by negligence.
