Title:
PIPELINE INSPECTION ROBOT HAVING CROSS VARIABLE-STRUCTURE CRAWLER BELT AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/212974
Kind Code:
A1
Abstract:
Disclosed in the present invention are a pipeline inspection robot having a cross variable-structure crawler belt and a control method therefor. The pipeline inspection robot comprises a robot body, crawler belt inclination angle adjustment mechanisms symmetrically arranged on the left and right sides of the robot body, and cross variable-structure crawler belt assemblies arranged on the crawler belt inclination angle adjustment mechanisms; the robot body is connected to the cross variable-structure crawler belt assemblies on the left side and the right side of the robot body by means of the crawler belt inclination angle adjustment mechanisms, and the crawler belt inclination angle adjustment mechanisms perform adjustment by means of support slide blocks at the bottom of the robot body; each cross variable-structure crawler belt assembly comprises a main advancing crawler belt, an auxiliary advancing crawler belt, and a cross variable-structure slide block; and the main advancing crawler belt and the auxiliary advancing crawler belt are connected by means of the cross variable-structure slide block. According to the present invention, the crawler belt structures can be changed, and each group of variable-structure crawler belt structures are independent, so that the robot has good flexibility to climb a slope and climb over obstacles to adapt to a complex environment in a pipeline.
