Problems solved by technology

When maintenance personnel encounter an obstacle (connecting pipe or reinforcing bar) on the speeding car, due to the limitation of the pulley design, the flying car cannot pass the obstacle (connecting pipe or reinforcing bar) and continue to move forward. Realize continuous operation in the same gear, which brings troubles to the maintenance work of transmission lines and prolongs the maintenance time of transmission lines

Abstract

The invention relates to a one-line operation trolley for a power transmission line. The one-line operation trolley comprises two support rods, wherein the two support rods are connected through a plurality of connecting rods which are arranged at intervals; the upper parts of the two support rods are movably connected with head pulleys respectively; the two head pulleys are arranged in a straight line; a plate body is arranged on the upper parts of the two support rods; the top ends of the two support rods are fixedly connected with the middle part of the plate body; and spanning auxiliary devices are respectively arranged on two sides of the plate body. The one-line operation trolley for the power transmission line is reasonable in structural design, and is capable of spanning obstacles; continuous operation within the same transmission line segment is realized; and the work efficiency is improved.

Description

technical field [0001] The invention relates to a single-line operation flying car of a power transmission line. Background technique [0002] Transmission lines, especially high-voltage power transmission and transformation lines, are erected at high altitudes. When overhauling them, it is necessary to use flying cars to carry out outgoing operations. The running of the existing flying car is realized by relying on the drop generated by the suspension of the wire and manually grasping and pulling the wire. When the maintenance personnel take the flying car and encounter an obstacle (connection pipe or reinforcement strip), due to the limitation of the pulley design, the flying car cannot continue to move forward through the obstacle (connection tube or reinforcement strip), and must perform multiple operations. The realization of continuous operation within the same gear brings trouble to the maintenance work of the transmission line, and prolongs the maintenance time of t...
