Abstract

The invention relates to a trolley used for maintenance of electricity overhead power transmission line. The invention is characterized in that the trolley comprises a frame, the upper part of the frame is provided with a seton pulley rotating around a fixed axis, a charging port is arranged on the frame below the seton pulley, the lower part of the frame is provided with a coaxial fixed-axis rotating ladder head traction pulley and a back-up protection rope pulley, the top of the frame is hinged with a control rod; the lower end of the control rod is provided with a damping slow rope device,the damping slow rope device is in the structure that a support is fixedly connected with the lower end of the control rod, the support is internally provided with a fixed clamping piece and an opposite movable clamping piece, and a screw fixedly connected with the movable clamping piece is connected with a nut of the support. The invention has the advantages that structure is simple, operation is simple, use is safe and reliable, personnel and time are saved, live-wire work can be carried out, and operation efficiency is high.

Description

technical field [0001] The invention relates to an appliance for overhauling an overhead electric power transmission line, in particular to a trolley for overhauling an overhead electric power transmission line. Background technique [0002] In the daily power maintenance work, because the conductor and ground wire of the overhead transmission line are bare wires and are located outdoors, they are easily damaged by various external forces, such as: wind, lightning strikes, ice coating, kites, wild bird activities, etc. Defects such as broken strands and anti-vibration hammer falling off occur. To deal with the above defects, we need to go to the running guide and ground to do the work. The prior art usually adopts two methods of outlet. [0003] 1. Speeding out of the line: First, the line is powered off. At least 6 operators are required to arrive at the operation site, including 2 operators on the tower and 4 on the ground. The operators on the tower take the transfer ...
