The mechanical lock rod rotary drilling rig is widely used in construction. Whether the drill pipe unlocking operation is standardized directly affects the construction safety and efficiency. If the unlocking process is improper, it may not only cause damage to the device but also pose significant security risks. The following is a detailed introduction to the correct process of unlocking the drill pipe of the mechanical lock rod rotary drilling rig.
1. Confirm the construction status: After the operation is completed, first move the drilling rig to a safe and flat area, turn off the engine, and ensure that the entire machine is in a stationary and unloaded state to prevent unexpected movement when unlocking.
2. Inspect the condition of the drill pipe: Carefully examine the connection parts of the drill pipe to ensure there is no dirt or debris blocking. Check whether key components such as the lock pin and the slot are in good condition to avoid any impact on unlocking due to component issues.
3. Operate the unlocking device: Start the unlocking hydraulic system, slowly operate the control handle to gradually release the unlocking mechanism, and at the same time observe the pressure value on the instrument to keep the pressure stable within the specified range.
4. Segmented lifting of drill pipes: In the order from top to bottom, lift one section of drill pipe at a time. During the lifting process, pay attention to keeping the drill pipe vertical to prevent it from colliding with other components.
5. Cleaning and Maintenance: After unlocking is completed, promptly clean the oil stains and dirt on the surface of the drill pipe and the connection parts, apply lubricating grease to the lock pins, slots and other components, and carry out daily maintenance.
6. Recording and Review: Record all the data during the unlocking operation in detail, recheck the status of the drill pipe, and only after confirming that there are no abnormalities can the subsequent equipment be parked or transferred.
In conclusion, the unlocking of the drill pipe of the mechanical lock rod rotary drilling rig must strictly follow the above steps. From the preparation and inspection after the operation, to the standardized unlocking operation, and then to the subsequent maintenance and record-keeping, each link is of vital importance. A standardized unlocking process can not only ensure construction safety, but also effectively extend the service life of equipment and improve construction efficiency.
