Problems solved by technology

[0002] Existing geological exploration and engineering construction drilling drill pipes are connected by threaded connections, and high-pressure flushing fluid needs to pass through the drill pipes, so the two joints need to be well sealed, and there are mainly the following disadvantages: (1) Stress concentration weakens the strength of the drill pipe joint, and frequent drill pipe joint breakage accidents; (2) Pipe tongs or free tongs are required to disassemble the connection in the application, and it is difficult to deploy tools in narrow construction sites or when working at high altitudes. It is very difficult to connect, and it is expensive to use twisting mechanical disassembly equipment

Abstract

The invention provides a bolt type tool joint which comprises a male tool joint body, a female tool joint body and a bolt. A first bolt opening is formed in the male tool joint body, a second bolt opening is formed in the female tool joint body, the bolt penetrates through the first bolt opening and the second bolt opening, the bolt is a rectangular right-angle table body, and the width of the bolt is smaller than the diameter of the male tool joint body. The bolt type tool joint is convenient to detach and can be conveniently used by a user.

Description

technical field [0001] The present invention relates to a plug type drill pipe joint. Background technique [0002] Existing geological exploration and engineering construction drilling drill pipes are connected by threaded connections, and high-pressure flushing fluid needs to pass through the drill pipes, so the two joints need to be well sealed, and there are mainly the following disadvantages: (1) Stress concentration weakens the strength of the drill pipe joint, and frequent drill pipe joint breakage accidents; (2) Pipe tongs or free tongs are required to disassemble the connection in the application, and it is difficult to deploy tools in narrow construction sites or when working at high altitudes. It is very difficult to connect, and it is expensive to use the pipe twisting mechanical disassembly equipment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a plug-type drill pipe joint, which is easy to disa...
