Device for automatically replacing drill rod of drilling machine

Abstract

The invention discloses a device for automatically replacing a drill rod of a drilling machine. The device comprises a drilling machine body side plate, a swing oil cylinder base, a turnover mechanism, a positioning device, a drill rod clamping mechanism and a drill rod rotary feeding mechanism. The swing oil cylinder base is fixed to the drilling machine body side plate, the turnover mechanism is fixed to the swing oil cylinder base through a bolt, the positioning device is fixed to the drilling machine body side plate, the drill rod clamping mechanism is fixed to a turnover arm frame, and the drill rod rotary feeding mechanism is arranged on the drill rod clamping mechanism. The device is simple in structure and convenient to use. The drill rod is directly placed in the drill rod clamping mechanism and accurately reaches the preset position under the action of the swing oil cylinder base and the positioning device, the drill rod is in thread pairing with a previous drill rod and does feeding motion under the action of the rotary feeding mechanism, and the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of gas exploitation, and in particular relates to a device for automatically replacing drill pipes of a drilling machine. Background technique [0002] At present, the drill pipe replacement work of most coal well drilling rigs in China mainly relies on manual replacement of the drill pipe. The worker carries the drill pipe, lifts the drill pipe to the power head of the drilling machine, and cooperates with the previous drill pipe, and so on. Work. This kind of working method is not only very inefficient, but also has certain risks. Especially for some heavy drill pipes, at least two people are often required to carry them. Time-consuming and labor-intensive. Therefore, it is necessary to provide a mechanical device that can effectively solve the above problems. Contents of the invention [0003] The purpose of the present invention is to solve the above technical problems. It provides a device for auto...
