Drill rod replacement mechanism for drill rod equipment

Abstract

The invention relates to the technical field of drill rod equipment, in particular to a drill rod replacement mechanism for drill rod equipment. The mechanism comprises an auxiliary unit and a support column; the auxiliary unit comprises a limiting platform; a conveyor belt is arranged at the top of the limiting platform; a plurality of carrier rollers are arranged in the middle of the conveyor belt; and the top faces of the carrier rollers are tightly attached to the inner side of the top face of the conveyor belt. According to the drill rod replacement mechanism for the drill rod equipment, a drill rod is pushed to the bottom end of the conveyor belt, a motor drives the conveyor belt to operate, the carrier rollers keep the top face of the conveyor belt smooth and stable, the conveyor belt drives the drill rod on the top to move upwards and be connected with a circular groove in a clamped mode, and a hydraulic cylinder supports a limiting platform to rotate upwards around a supporting block, so that the inclination degree of the drill rod can be adjusted, a worker can conveniently carry the drill rod to the inner side of the limiting platform, and the drill rod on the inner side of the limiting platform can be conveniently adjusted to be vertically arranged; and clamping and vertical fixing of the drill rod are completed through two clamping modules, so that the risk caused by mechanical faults during working is reduced, and the replacement efficiency of the drill rod is improved.

Description

technical field [0001] The invention relates to the technical field of drill pipe equipment, in particular to a drill pipe replacement mechanism for drill pipe equipment. Background technique [0002] When the drill pipe equipment is drilling the bottom layer, due to long-term friction and mechanical vibration of the drill bit, the thread ring of the drill pipe will wear out. When drilling in the vertical direction with complex soil quality, it is necessary to replace the drill pipe frequently for maintenance. Prevent the friction ring of the drill pipe from being stuck with the clamping device, resulting in the inability to disassemble the drill pipe and delaying the construction period. [0003] During the production process, workers need to clamp two vises to the connecting section of the drill pipe and the close position of the drill pipe respectively, and the operator adjusts the rotational speed of the drill pipe clamping module to remove and install the drill pipe. I...

AI Technical Summary

Problems solved by technology

It is very dangerous to operate the vise close to the large drill pipe equipment, and requires tacit cooperation with the operator. At the same time, the installation and removal of the drill pipe is mostly assisted by artificial shoulder resistance or mechanical arm guidance, which consumes a lot of physical strength of the workers.
