A detachable connecting drill pipe

Abstract

The invention discloses a detachable connecting drill rod. The detachable connecting drill rod comprises an upper drill rod body, a lower drill rod body and a connecting pipe sleeve; the upper drill rod is of a hollow structure, one end of the detachable connecting drill rod is an upper connecting end which is in a semi-circular shape, and the outer surface of the upper connecting rod is provided with a thread; the lower drill rod body is of a hollow structure, one end of the lower drill rod body is a lower connecting end which is in a semi-circular shape, and the outer surface of the lower connecting end is provided with a thread; the inner wall of the connecting pipe sleeve is provided with a thread; and under an assembly state, the upper connecting end of the upper drill rod body and the lower connecting end of the lower drill rod body are inlaid through connecting pieces to form an integral circular pipe, the connecting pipe sleeve is installed on the connecting position of the upper drill rod body and the lower drill rod body in a sleeving mode, and the thread on the inner wall of the connecting sleeve pipe is engaged with the threads of the upper drill rod body and the lower drill rod body. The detachable connecting drill rod is compact in structure, good in airtightness and convenient to assemble and disassemble, an outer thread of the pipe sleeve only has a sealing connecting effect and does not need to bear delivered torque force, and stress of the threads of the pipe sleeve is effectively reduced.

Description

technical field [0001] The invention relates to the field of geological exploration machinery, in particular to a detachable connecting drill pipe. Background technique [0002] With the rapid development of modern technology, automated and intelligent equipment is serving all walks of life, but in the field of geological exploration such as drilling, the degree of automation of equipment is very low. Due to the particularity of work, this field is usually located in remote mountains or very remote In the region, the working conditions are poor, the conditions and facilities are insufficient in all aspects, and the relative closure of the industry makes it difficult for automation and intelligent equipment with cross-industry to enter this field. Therefore, in actual working conditions, the improvement of drilling equipment is kept at the level of optimization and innovation of pure mechanical structure. Based on actual conditions, the patent of the present invention is also...
