摘要： The present invention discloses a pipeline patrol inspection robot having variable tracks and a control method therefor. The pipeline patrol inspection robot of the present invention includes a robot body, track assemblies symmetrically disposed on a left side and a right side of the robot body, and a movement driving mechanism. The robot body is connected to the track assemblies on the left side and the right side by track fixtures, and track angle adjusting mechanisms are respectively connected between the robot body and the track assemblies on the left side and the right side. By means of the present invention, a track camber angle can be adjusted. In addition, each track angle adjusting mechanism is independent, and has desirable flexibility to adapt to different pipeline environments.

摘要： The present disclosure discloses a pipeline inspection robot with crisscross structure-changeable crawler belts and a control method thereof. The pipeline inspection robot 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. According to the present disclosure, a crawler belt structure can be changed, and each set of structure-changeable crawler belt structure is independent and has very good flexibility for climbing and crossing over obstacles to adapt to complex environments in pipelines.
