Abstract

The invention discloses a telescopic self-lock type intra-pipe movable robot. An existing pipeline robot is low in loading capacity and poor in stability, and an operation device under a high-resistance condition still has serious defects. A front cart body assembly of the telescopic self-lock type intra-pipe movable robot is provided with a front self-lock mechanism assembly. A rear cart body assembly is provided with a rear self-lock mechanism assembly. A moving pair is formed by the front cart body assembly and the rear cart body assembly through guide rods and guide sleeves. A threaded shaft of a driving assembly is in spiral transmission with a front cart body. Rotation of a driving motor is converted into movement of the front cart body assembly and movement of the rear cart body assembly so that the intra-pipe robot can be driven. According to the telescopic self-lock type intra-pipe movable robot, it is guaranteed that the robot is in full contact with the inner wall of a pipeline through the front self-lock mechanism assembly and the rear self-lock mechanism assembly, and the stability and loading capacity of the robot inside the pipeline are effectively improved; it is guaranteed that pressing force exists all the time between the self-lock mechanism assemblies and the inner wall of the pipeline through pressure springs, and the movement stability of the robot inside the pipeline is guaranteed; in addition, the spiral pair formed by the front cart body assembly and the rear cart body assembly has a self-lock function, and therefore the robot can be stopped and locked in any position.

Description

technical field [0001] The invention belongs to the technical field of robots, and relates to a pipe mobile robot, in particular to a telescopic self-locking pipe mobile robot. Background technique [0002] Most of the pipelines in the industrial pipeline system are straight pipes, and some pipelines are liquid inside. In order to ensure the safe and efficient operation of each pipeline system, it is necessary to use pipeline robots to complete inspection and maintenance. Existing pipeline robots can move and work in pipelines, but their loads are small and their stability is poor, and there are still serious defects in the working devices of mobile robots in pipelines under conditions of large resistance. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art, and provide a telescopic self-locking mobile robot in a pipe. The mobile robot in a pipe ensures full contact with the inner wall of the pipe through ...
