A live working robot for repairing broken strand wires

Abstract

A live working robot for repairing broken strand wires with protective wires, including a walking carrier, an obstacle avoidance mechanism, and a broken strand repair operation device; One is connected with the vertical movement mechanism through the rotary joint, and the upper end of the vertical arm is connected with the walking carrier; the device for repairing broken strands includes a left and right translation mechanism, and the cross arm is equipped with a front and rear translation mechanism. On the translation mechanism and perpendicular to the cross arm, the two ends of the left and right translation mechanism are equipped with a support mechanism, the middle is fixed with a limit mechanism and a winding mechanism, a guide mechanism, and a composite mechanism are installed in a sliding manner; Wiping, grease, crimping operations. The invention can realize the full coverage and integrity repairing of multi-split line conductors, and at the same time clean, grease and repair the surface of the conductors to ensure that the conductors maintain good electrical conductivity.

Description

technical field [0001] The invention relates to the field of high-voltage transmission line operation robots, in particular to a live-line operation robot for repairing broken wires with protective wires. Background technique [0002] Overhead transmission lines are an important part of my country's power grid. During their long-term operation, they are completely exposed to the natural environment, affected by severe weather such as thunderstorms and snowstorms, coupled with alternating stress such as vibration and galloping, and mutual friction between strands. , Overhead transmission line conductors are prone to failures such as conductor wear, broken strands and loose strands. If the wear and tear of the wires and broken strands are not eliminated in time, as time goes by, it will gradually evolve into a large area of ​​broken strands or even broken wires, seriously affecting the safe operation of overhead transmission lines. The repair of broken strands and loose strand...

AI Technical Summary

Problems solved by technology

The above-mentioned repairing robot or repairing method is only applicable to the single-line repairing operation of the robot walking line, and cannot carry out operations on other lines of the multi-split line. In addition, the former only uses crimping clips to repair the wires that are not aligned with the outer guard wires of the wires. Although the latter has re-twisted the outside of the wire, it has not further treated the surface of the wire during the twisting process, and cannot guarantee the cleanliness of the wire surface and the conductivity of the wire.
