Abstract:

High-voltage transmission line inspection robot, as a kind of intelligent power grid operation and inspection equipment instead of human inspection, has a broad industrial market prospect due to its advantages of high intelligence, high efficiency and high quality of inspection. The overarm inspection robot is designed on the basis of bionics principle and with reference to sloth climbing characteristics, which has more advantages in lightweight design, operation efficiency and safety. The structure of the overarm inspection robot is distinctive, and crossing the pylon requires the use of the passage below the overhead line. Based on this feature, combined with the characteristics of overhead transmission lines, the movement of the robot across the pylon is planned, and a set of auxiliary tools is designed to solve the problem of the overarm inspection robot crossing the pylon, and the mechanical properties of stress, strain and displacement of the robot walking under normal working conditions are verified by statics simulation, and the application boundary conditions are determined.

Key words: Arm-crossing inspection robot, motion planning, auxiliary hardware, statics analysis
