Drilling machine and pipe mounting and dismounting device thereof

Abstract

The invention relates to a drilling machine and a pipe mounting and dismounting device thereof. The pipe mounting and dismounting device of the drilling machine comprises a clamp holder, a power unit,a mast, a controller and a displacement sensor, wherein the displacement sensor is used for detecting displacement of the power unit on the mast and feeding the displacement back to the controller; the controller is used for controlling the clamp holder and the power unit to achieve pipe mounting and dismounting operation. Compared with existing manual operation, the pipe mounting and dismountingdevice of the drilling machine facilitates operation by an operator, saves labor and operating cost and improves the working efficiency of the drilling machine.

Description

Technical field [0001] The invention relates to the technical field of engineering machinery, and in particular to a rod up and unloading device for a drilling rig and a drilling rig. Background technique [0002] During the construction of the multifunctional drilling rig, the clamper cooperates with the power head to disassemble the drill rod. The connection between the upper and lower drill rods needs to stay between the shackle clamp and the clamping fixture to be able to disassemble the drill rod, but in the actual work process, the operator needs to operate at the console, and then another worker cooperates on the working surface Observe the drill pipe from time to time to locate the joint of the drill pipe. However, because the drill pipe is often covered with soil, it is difficult to accurately observe and affect the construction efficiency; and when using the clamp to clamp the drill pipe, you can only rely on the working experience of the operator Or use the rotation o...

AI Technical Summary

Problems solved by technology

The connection between the upper and lower drill pipes needs to stay between the shackle fixture and the clamping fixture before the drill pipe can be disassembled. However, in the actual work process, the operator needs to operate on the console, and then another worker cooperates on the working surface Always observe the drill pipe to locate the joint of the drill pipe, but because the drill pipe is often covered with soil, it is difficult to observe accurately, which affects the construction efficiency; and when using the clamper to clamp the drill pipe, you can only rely on the experience of the operator Or use the rotation of the power head to judge whether it is clamped, and the work efficiency is extremely low; when disassembling the drill pipe, the power head needs to be actively fed to the joint of the drill pipe. This operation is manually controlled by the operator, and its accuracy is limited by the machine. Hand experience and mental state, in the actual work process, it is very likely that excessive feed will cause irreversible damage to the drill pipe thread
