Single-driving double-directional crawling-type pipeline cleaning robot

Abstract

The invention discloses a single-driving double-directional crawling-type pipeline cleaning robot. The single-driving double-directional crawling-type pipeline cleaning robot comprises a front machine body assembly, a transmission assembly and a rear machine body assembly. Through the condition that the transmission assembly is driven by a power assembly and through the transmission effect of a link mechanism, a gear mechanism and an equal-interval cam mechanism, alternant contracting and supporting of the front machine body assembly and the rear machine body assembly in the radial direction are achieved, stretching out and drawing back of the front machine body assembly and the rear machine body assembly in the axial direction are achieved, and meanwhile synchronous rotation of a dredging knife flywheel is achieved, so that crawling-type travelling of the robot in the positive and negative directions of a pipeline and pipeline cleaning operation are achieved. The single-driving double-directional crawling-type pipeline cleaning robot is stable, reliable, compact and practicable, achieves single-driving double-directional crawling-type travelling and pipeline cleaning in the pipeline with large pipe diameter changing, effectively improves the obstacle crossing property and pipe diameter changing adaptability of the pipeline robot, improves the cruising ability of the pipeline robot and has a practical engineering significance on cleaning of the horizontal pipeline with large pipe diameter changing.

Description

technical field [0001] The invention relates to the technical field of a horizontal pipeline cleaning robot, in particular to a pipeline cleaning robot that realizes single-drive two-way peristaltic walking in horizontal pipelines with large diameter changes based on the coordination of equal-rest cam groups. Background technique [0002] In recent years, the demand for automation and intelligent operations of pipeline cleaning has been increasing at home and abroad. At present, domestic cleaning methods mainly rely on manual work, the working environment is complex and harsh, labor-intensive, and highly dangerous. During the pigging operation, the peristaltic pipeline robot has greater traction capacity and terrain adaptability, and is more suitable for pipeline cleaning operations. However, most of the existing pigging robots and pigs only have the ability to walk in one direction. During the cleaning process, once a special obstacle is encountered, the robot cannot conti...
