Abstract
A pipeline inspection robot with crisscross structure-changeable crawler belts includes a robot main body, crawler belt tilt angle adjustment mechanisms symmetrically provided on left and right sides of the robot main body, and crisscross structure-changeable crawler belt assemblies provided on the crawler belt tilt angle adjustment mechanisms. The robot main body is connected to the crisscross structure-changeable crawler belt assemblies at the left and right sides thereof by means of the crawler belt tilt angle adjustment mechanisms. The crawler belt tilt angle adjustment mechanisms are adjusted by means of supporting sliding blocks at the bottom of the robot main body. The crisscross structure-changeable crawler belt assembly includes a primary traveling crawler belt, an auxiliary traveling crawler belt, and a crisscross structure-changeable sliding block. The primary traveling crawler belt and the auxiliary traveling crawler belt are connected by means of the crisscross structure-changeable sliding block.
