AI Technical Summary

Problems solved by technology

When disassembling the drill pipe, due to the long length of the drill pipe, the axis of the drill pipe tends to deviate from the center of the dismounting mechanism. The drill pipe is deformed or damaged, which affects the repeated use of the drill pipe and the drilling operation of the drilling machine

Abstract

The invention relates to a drill pipe dismounting mechanism comprising a positioning device, a fixing device and an actuating device, wherein the positioning device is used for limiting dismounting position of a drill pipe, the fixing device is used for limiting movement of the drill pipe at the dismounting position, and the actuating device is used for driving the drill pipe at the dismounting position to rotate around its axis. Besides, the positioning device comprises a fixed block and a moving block matched with each other for limiting the preset axis, the fixed block is fixed relative tothe fixing device, the moving block is selectively fixed relative to the fixing device, so that the drill pipe is allowed to enter or exit the dismounting position, and further, the moving block and the fixed block are matched to limit moving of the drill pipe; when the drill pipe is at the dismounting position, its axis and the preset axis coincide. In application of the drill pipe dismounting mechanism, offset of the axis of the drill pipe is prevented during dismounting, and deformation or damage of the drill pipe during dismounting is then avoided.

Description

technical field [0001] The present disclosure relates to the technical field of drill rod dismounting, and in particular, relates to a drill rod dismounting mechanism. Background technique [0002] When the existing equipment is used for drilling operations, different sizes and types of drilling tools will be used for operations due to different engineering conditions. When the drilling rig performs deep hole drilling operations, the head and tail threads of a plurality of drill rods are usually connected, and after the drilling is completed, the drill rods need to be disassembled. Due to mechanical inertia, the drill pipe will get tighter and tighter in actual work. If the drill pipe is disassembled by a wrench, the workman will be very strenuous when disassembling the drill pipe, and many people are often needed to complete the disassembly work of the drill pipe. Due to the tight connection of the joints of the drill pipe, if the drill pipe is disassembled directly by rev...
