The invention discloses a power transmission line bolt cotter pin live-line supplementary installation system, which comprises a supplementary installation tool and a ground station. The supplementary installation tool is in wireless communication connection with the ground station, the ground station is used for remotely monitoring and controlling the supplementary installation tool, and the supplementary installation tool comprises a handle, an annular motor, a nut, a guide sleeve and a pin. A nut is installed on an output shaft of the annular motor, a guide sleeve is arranged on the outer side wall of the nut, the nut is provided with a through hole communicated with the guide sleeve, and a pin is inserted into the guide sleeve. The system has the technical effects that: through the power transmission line bolt cotter pin live-line supplementary installation system of the invention, the installation steps are simplified, the working efficiency is improved, hot-line installation can be completed, and economic losses caused by power failure are reduced; and reinforcing and supplementing operation of bolts of different models can be met, and remote video monitoring of the tightness state of the screw and real-time observation of the screw fixing process are achieved.
Description
Technical field [0001] Technical Field The present invention relates to a tool assembly, in particular to a transmission line cotter bolt retrofitted charging system. Background technique [0002] High-voltage transmission lines charged with the task of power transmission in our country, it's safe and reliable operation is directly related to the stable development of the national economy. [0003] Currently, high pressure and EHV power line is the main form of long-distance power transmission and distribution, transmission lines Clamp bolt force receiving member is important to maintain wires and the tower linked, long exposure to the environment, not only to bear all the tension of the wire, but also to withstand dirty, lightning, and strong against the outside world, would enable bolts loose or fall off, if not reinforced or reinstall, you can develop into a variety of failures, operational security and stability of the power system threatening. Usually off retrofitted require...
