The Correct Unlocking Method of The Mechanical Lock Rod Rotary Drilling Rig During The Construction Process

In the operation of the mechanical lock rod rotary drilling rig, correct unlocking is a key link to ensure the safety of the equipment and the construction efficiency. If the unlocking method is improper, it may lead to equipment failure or safety hazards. The following are six correct ways to unlock during the construction process:

1. Confirm the working conditions: Ensure that the drilling rig is stationary, the power head has stopped rotating, and the drill pipe is perpendicular to the ground to avoid unlocking when shaking or tilting.

2. Operating the hydraulic system: Slowly operate the hydraulic control handle to release the pressure of the locking mechanism. Observe that the pressure gauge value steadily drops to the safe range before proceeding to the next step.

3. Manual auxiliary unlocking: If the hydraulic unlocking is blocked, you can gently push or pull the drill pipe for assistance, but do not use brute force to strike to prevent damage to the locking components.

4. Check the unlocking status: After unlocking, visually confirm that the lock pin has completely withdrawn from the lock hole, or judge through the indicator light on the device's dashboard to ensure there is no jamming.

5. Layered and segmented unlocking: When performing deep hole operations, the drill pipe should be lifted layer by layer. Repeat the unlocking steps after lifting a certain distance to avoid excessive load caused by one-time unlocking.

6. Handling of abnormal situations: In case of difficulty in unlocking, immediately stop the machine for inspection to eliminate foreign object blockage or component wear issues. Forced operation is strictly prohibited.

Conclusion: To correctly master the unlocking method of the mechanical lock rod rotary drilling rig, it is necessary to strictly follow the operation procedures and operate scientifically in combination with the equipment status and working conditions. Standardized unlocking steps can not only extend the service life of the equipment, but also effectively reduce construction risks, ensuring the safety and progress of the project.
