Pipeline inspection robot

Abstract

The invention provides a pipeline inspection robot. The robot mainly comprises parts of a cover plate supporting column, a cleaning motor, travelling motors, supporting arms, a triangular plate, a ball screw, a connecting bolt and lifting plates. According to the pipeline inspection robot, a roller movement mode is adopted, electric drive is adopted, the lifting plates are driven to move upwards or downwards through the ball screw, so that the movement of the first lifting plate or the movement of the second lifting plate drives the supporting arms to lift and fold upwards to be close to the ball screw or to drop and expand downwards to be far away from the ball screw; therefore, the pipeline inspection robot can correspondingly control rollers at the end parts of the supporting arms according to the size of a pipeline, so that the rollers can be kept in close abutting connection with the inner wall of the pipeline, then the position of the pipeline inspection robot in the pipeline canbe maintained through the abutting action of the rollers, and driving and control of the pipeline inspection robot running up and down are achieved; and therefore, the pipeline inspection robot not only maintains certain pipeline passing performance but also has certain speed.

Description

technical field [0001] The invention relates to the field of robots, in particular to a pipeline inspection robot. Background technique [0002] Cracks and blockages caused by aging pipelines require regular maintenance. Due to the limitations of the inner diameter of the pipeline and the internal and external environment, it is usually necessary to rely on pipeline robots for inspection and maintenance. However, due to the variety of pipeline sizes and setting environments, it is unrealistic to design different pipeline robots for each size and type of pipeline according to its inspection requirements. [0003] At present, the walking modes of pipeline robots include: peristaltic movement, crawler movement, roller movement, leg movement, piston movement and so on. But each of these walking modes has its shortcomings. On the one hand, the above-mentioned driving methods need to design corresponding structures according to the inner diameter of the pipeline, and it is diff...
