Abstract

The invention discloses a drilling and cutting integrated drill pipe. A drill pipe body comprises a through hole, a male connector and a female connector, wherein the through hole penetrates in the axial direction, and the male connector and the female connector are matched and arranged at the two ends of the drill pipe body respectively; the position, located at one end of the drill pipe body, of the through hole is of a conical structure; a hole sealing assembly is placed in the through hole and comprises a conical hole sealing plug and a pressure adjusting spring; the larger end face of the conical hole sealing plug is connected with one end face of the pressure adjusting spring; the hole sealing plug is matched with the conical structure of the through hole and used for sealing the through hole; a jet hole assembly is arranged in the drill pipe body and comprises a jet through hole, and the jet through hole is perpendicular to the through hole in the drill pipe body and located behind the hole sealing plug.

Description

technical field [0001] The invention belongs to the technical field of coal mining, and relates to equipment in the construction process of pre-extraction gas channels before official coal mining, in particular to a drilling and cutting drill pipe device for pre-extraction gas channels, which is used to solve the existing drill pipe construction process The problem of low efficiency caused by frequent ups and downs in the medium. Background technique [0002] Coal mine gas and dust accidents are one of the major underground disasters. If a gas and dust accident occurs, it will not only seriously damage the production environment, but also cause casualties, causing huge losses to the people, enterprises, and the country. Therefore, the elimination of gas overrun Gas and dust are the preconditions for preventing gas and dust accidents, and are also one of the important guarantees for safe production in mines. [0003] However, due to geological deposition, a large amount of g...
