Live-line work robot for repairing broken strand lead by protecting line

Abstract

The invention discloses a live-line work robot for repairing a broken strand lead by a protecting line, and the robot comprises a walking carrier, an obstacle avoidance mechanism and a broken strand repairing working device; the obstacle avoidance mechanism comprises a vertical arm and a transverse arm I; the vertical arm is provided with an up-down longitudinal moving mechanism, the transverse arm I is connected with the up-down longitudinal moving mechanism through a rotary joint, and the upper end of the vertical arm is connected with the walking carrier; the broken strand repairing operation device comprises a left-right translation mechanism, a front-back translation mechanism is arranged on the first cross arm, the left-right translation mechanism is installed on the front-back translation mechanism in a sliding mode through a front-back translation joint and is perpendicular to the transverse arm I, and clamping mechanisms are installed at the two ends of the left-right translation mechanism. A limiting mechanism is fixedly mounted in the middle; a winding mechanism, a guide mechanism and a compounding mechanism are slidably mounted; and the composite mechanism carries out wire stroking, wire wiping, greasing and crimping operations on the wire and the wire pressing strip. According to the invention, full-coverage and integrity repair operation for the multi-split line conductor can be realized, and meanwhile, the surface of the conductor is cleaned, greased and repaired to ensure that the conductor maintains good 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.
