This invention relates to the field of cable inspection and maintenance technology, and discloses a robot for the operation and maintenance of power transmission lines in mountainous areas. The robot includes a main body, a sliding buffer assembly, a camera inspection assembly, a positioning assembly, and a drive assembly. The sliding buffer assembly decouples the camera mechanism from the robot body through a sliding groove and a slider, allowing the robot to move forward continuously at a constant speed while the camera mechanism remains stationary, eliminating motion blur and channel misalignment. Driven by the drive assembly, the positioning assembly first stretches the cable section to be tested axially and then pushes it axially, forcibly opening circumferential and axial micro-cracks to facilitate the visualization of early damage. Four sets of multispectral high-definition cameras in a ring array employ an intermittent static shooting strategy, requiring only one key image to be acquired for each detection section during the stretching and pushing states. This invention achieves high-precision, low-miss-rate detection of micro-cracks in cables in mountainous areas, simplifies the system structure, and improves the robot's portability and operational stability.
