Background technique

Under the effect of the rapid development of modern science and technology, with the continuous improvement of the design level of power transmission, the height of the iron tower is increasing year by year. The traditional rope-throwing method of hanging the overhead block is difficult to succeed. Only by personnel climbing up the pole tower to hang the overhead block, and using the overhead block to deal with defects such as broken wires on the wire. However, during high-voltage power transmission, it is often necessary to divide a high-voltage line of a certain phase into two sub-conductors, also known as "high-voltage horizontal double-split lines", which is convenient for manufacturing and construction, and can also transmit a larger amount of current. Between the two sub-conductors Spacer bars are usually provided at intervals to prevent the two sub-conductors from overlapping and to ensure a certain distance between the two sub-conductors. If the defect on the wire is in the middle of the two spacers, it is difficult for the overhead block to reach the defect for maintenance. Therefore, it is necessary to design a more convenient tool to handle the defect on the wire between two spacers.
