In the power system, tower heights vary with different voltage levels. During operation, the suspension clamp in overhead transmission lines may loosen or fall off because the pins are easily affected by external forces. For suspension clamps with different voltage levels, this article designs an intelligent installation tool for live working pins that can communicate wirelessly by studying the R-pinhole positioning system, which can achieve the installation of pins with different orientations. Firstly, the mechanical structure for pin installation was designed; secondly, precise positioning of the pinhole was achieved by using ball-head screws and photoelectric sensors; then, by designing a wireless communication module, precise control of its various functions was achieved; finally, basic functionality and on-site testing were conducted on the designed intelligent pin installation tool. The results show that the average installation time of the designed tool is about 2 minutes. Compared with manual equipotential operation, it greatly improves work efficiency, reduces the labor intensity of operators, and improves the safety factor introduction.
