Problems solved by technology

Due to the radial runout of the drill bit when it encounters an obstacle during surveying, there will be a brief separation between the conductive column and the conductive ring on the output shaft, which will cause the interruption of signal transmission, so it will also directly affect the operator Judgment on the trajectory of the pilot hole; if the vibration of the drill bit is large, the output shaft may damage the conductive column, thus affecting the guidance survey of the wired guidance system and reducing work efficiency

Abstract

The invention relates to a wired signal transmission device, in particular to a signal transmission device in a wired guide system of a horizontal directional drilling machine. The device comprises a conductive post (1) and a wire (2), and further comprises a conductive post support (3) arranged on the horizontal directional drilling machine, the top of the conductive post support (3) is connected with the wire (2), the conductive post support (3) comprises a shell (31), a cavity (31) capable of containing the conductive post (1) is formed in the shell (33), a spring (4) is disposed between the conductive post (1) and the top of the cavity (31), and the lower end of the conductive post (1) extends out of the cavity (31) and is in contact with a conductive ring on an output shaft (5) of the horizontal directional drilling machine. The spring is arranged above the conductive post, so that signal interrupt caused by radial jumping of the output shaft of the horizontal directional drilling machine is overcome, it is guaranteed that the conductive post is always in contact with the conductive ring on the output shaft, and accordingly guide drilling hole track control is more precise.

Description

technical field [0001] The invention relates to a signal transmission device, in particular to a wired signal transmission device in a wired guidance system of a horizontal directional drilling machine. Background technique [0002] Trenchless technology is to use jacking or drilling methods to form a pilot hole in the crossing area first, and then adopt corresponding methods to expand the borehole to the required diameter according to the actual engineering situation, and then complete the pipeline laying. Therefore, the key technology of trenchless pipe laying lies in the precise control of the directional drilling trajectory to ensure that the original underground pipelines and obstacles are avoided, and the pipe is laid accurately and smoothly according to the designed route. [0003] The control of the trajectory of the pilot hole depends on the signal emitted by the probe in the pilot drill bit, which is transmitted to the computer through the signal transmission devic...
