Design of Clamping Mechanism for Transmission Tower Climbing Robots

Aiming at the maintenance of dangerous parts of transmission tower，a new climbing robot is designed. According to the motion environment and clamping mode of the climbing robot，a composite structure combining magnetic adsorption and mechanical clamping is designed to ensure the reliability and accuracy of clamping. The clamping claw is driven by a motor and drives the screw elevator to move up and down through gear transmission，so as to realize the clamping of the claw to the angle steel. At the same time，the electromagnet adsorbs the angle steel to realize the double clamping of the angle steel，which effectively resists the danger of overturning and falling off of the climbing robot on the iron tower. The design process of electromagnetic adsorption clamping gripper is introduced，the three-dimensional model of gripper is established，the static analysis and simulation of gripper are carried out，and its rationality is verified by experiments.
