Title:
SINGLE-DRIVE BIDIRECTIONAL CRAWLING PIPELINE CLEANING ROBOT
Document Type and Number:
WIPO Patent Application WO/2018/205530
Kind Code:
A1
Abstract:
Provided is a single-drive bidirectional crawling pipeline cleaning robot, comprising a front machine body assembly (1), a transmission assembly (2) and a rear machine body assembly (3), wherein the transmission body (2) is driven by power, and by means of the transmission effect of a connecting rod mechanism, a gear mechanism and an equal-dwell cam mechanism, alternate contraction and support of the front machine body assembly (1) and the rear machine body assembly (3) in a radial direction are achieved, and the extension and retraction between the front machine body assembly (1) and the rear machine body assembly (3) in an axial direction are achieved, and synchronous rotation of a dredging knife flywheel is also achieved at the same time, such that a crawling movement of the robot in the forward and reverse directions of the pipeline and pipeline cleaning operation are achieved. The robot is stable, reliable, compact and feasible, achieves single-drive bidirectional crawling movement and pipeline cleaning in a pipeline with relatively great changes in the pipe diameter, and effectively improves the obstacle crossing ability and the adaptability to pipe diameter changes of the pipeline robot.
