Abstract

The invention discloses a milling cutter type horizontal well traction robot obstacle clearing mechanism, relates to a robot obstacle clearing mechanism, and aims to solve the problem that a robot can be easily blocked during movement in a horizontal well pipeline to fail to work normally so as to cause loss to exploitation and measurement of a horizontal well. According to the mechanism, a left end cover is connected with a shell; a left supporting block is arranged in a left deep groove ball bearing; a right supporting block is arranged on the right side of a motor magnetic pole; a right end cover is fixed to the shell; a milling cutter seat is arranged on the right end part of the right supporting block; a central shaft penetrates through the left end cover, the left supporting block, the motor magnetic pole, the right supporting block and the milling cutter seat in sequence; a pushing member is arranged on a first left angular contact ball bearing and a second right angular contact ball bearing in a sleeving manner; a left bearing baffle plate is arranged between the pushing member and the milling cutter; a T-shaped groove is formed in a sliding member and is in sliding fit with a T-shaped member of the pushing member; the sliding member is connected with the milling cutter seat; a sliding member baffle plate is matched with the sliding member. The mechanism is used for clearing obstacles for the robot in a horizontal well.

Description

technical field [0001] The invention relates to an obstacle clearing mechanism for a robot, in particular to an obstacle clearing mechanism for a milling cutter type horizontal well traction robot. Background technique [0002] In today's petroleum industry, due to the many advantages of horizontal wells, the research on horizontal well production technology has been paid more and more attention. However, the structure of horizontal wells is different from ordinary oil wells, and the detection of horizontal wells is also more troublesome than ordinary oil wells. At present, the detection of horizontal wells at home and abroad is realized by the horizontal well traction robot, and the horizontal well carries the detection instrument to crawl in the pipeline to detect the internal situation of the horizontal well. However, when the horizontal well traction robot moves in the horizontal well pipeline, it will encounter many situations, such as climbing, obstacles or getting st...
