Overhead ground wire lifter

Abstract

The invention relates to an overhead ground wire lifter which comprises a hoop, a transverse beam, suspension points and a fixed pulley. The transverse beam is arranged on the hoop, the suspension points are arranged on the transverse beam, the fixed pulley can be suspended on the suspension points, the rear end of the transverse beam is movably connected with the hoop, the middle of the transverse beam is lapped on the hoop, the front of the transverse beam extends out of the hoop, the suspension points are arranged on an extending portion of the transverse beam, one of the suspension points is connected with the fixed pulley, and a safety rope is wound on the fixed pulley. The overhead ground wire lifter has the advantages that the overhead ground wire lifter is simple in structure, can stably sleeve the top of an electric pole, is provided with the anti-drop safety rope and can be prevented from falling to injure ground personnel by means of crashing; the safety rope also can be used for lifting to-be-erected ground wires; overhead operation can be carried out on the ground wires at optional altitudes in service procedures; the overhead ground wire lifter is easy and convenient to operate, the quantity of overhead operation personnel can be effectively reduced, sufficient operation spaces can be reserved for the operation personnel, and accordingly a safety coefficient of overhead operation can be increased.

Description

technical field [0001] The invention relates to a lifting device, in particular to an overhead ground wire lifter used when erecting ground wires. Background technique [0002] Most of the transmission lines are erected outdoors. When the wind blows, the lines will swing with the wind. They are in a state of micro-vibration for a long time, which may easily cause the overhead ground wires in the suspension clamps to break. In the past, during maintenance, the operator carried the wire to be replaced to the top of the pole, and then set up the wire. Since the replacement of high-altitude lines requires multiple people to cooperate, and the space on the top of the pole is small, the operating space is also small, so the old-fashioned way of changing lines is extremely dangerous to operators. [0003] In order to solve the problem of high-altitude stringing, there are some lifting devices in the prior art that use pulleys and guy wires at high altitudes, and the new wires to b...

AI Technical Summary

Problems solved by technology

When it is connected with the pole, only the hoop is suitable for socketing, but the installation of the hoop requires positioning of its fastening bolts, and the hoop needs to be disassembled after application, which is cumbersome, especially when working at heights, and it is inconvenient to erect , not easy to operate

And if the bolts of the hoop are loose during installation, the hoop will easily slide down along the pole, causing accidents
