Problems solved by technology

[0002] In the past engineering drilling, the traditional circular cross-section holes were drilled in a straight line or a curve with a large turning radius, which could not realize a small radius turning, and the accuracy of controlling the direction of the turning hole was poor. Can be precisely controlled according to actual needs

Abstract

The invention discloses small-radius drilling equipment capable of accurately controlling a drilling direction. The mall-radius drilling equipment capable of accurately controlling the drilling direction comprises a connecting part, a passive turning part and an active turning part, the second end of the connecting part is fixedly connected with the first end of the passive turning part, the second end of the passive turning part is hinged with the first end of the active turning part, and the second end of the active turning part is hinged with a drill bit, and the active turning part drives the drill bit to steer. According to the mall-radius drilling equipment capable of accurately controlling the drilling direction, the connecting part is arranged, a rod body of the connecting part and a conversion joint are of a porous lotus-root-shaped structure, pore channels in the connecting part are mutually isolated, and the pore channels can be mutually sealed without a complicated sealing structure, so that different cables and pipelines can pass through the connecting part, and energy can be conveniently transferred downwards; and the conversion joint is connected, so that a steering requirement is met while energy transfer is realized.

Description

technical field [0001] The invention relates to the technical field of engineering drilling, in particular to small-radius drilling equipment that can precisely control the drilling direction. Background technique [0002] In the past engineering drilling, the traditional circular cross-section holes were drilled in a straight line or a curve with a large turning radius, which could not realize a small radius turning, and the accuracy of controlling the direction of the turning hole was poor. It can be precisely controlled according to actual needs. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is to provide a small-radius drilling equipment that can realize small-radius turning, facilitate direction control, and can precisely control the drilling direction. [0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a small-radius drilling equipment ...
