Abstract: Aerial work is a high risk procedure in power grid construction and operation. It is a vital issue to protect the workers’ safety while working on high tower or climbing tower. In this paper, a safety protection strengthening method is proposed based on tower-climbing robot assistance, and an iron tower climbing system with high flexibility and good obstacle-crossing ability is designed. The required functions are realized with the 3-leg silkworm-like main structure and the magnetic/clamping dual function craws. Through laboratory based experiment, the proposed system was proven to be able to move vertically or horizontally and turn around, with an ability to cross a 180 mm high and 400 mm wide obstacle. The proposed climbing system structure is applicable to the power tower climbing for assisting various aerial works.

Key words: climbing robot, aerial work, silkworm-like structure, obstacle crossing, aerial rescue
