Special conductor lifting device for 220KV horizontal double bundle conductor

Abstract

The invention relates to a tool for overhauling and maintaining a high voltage transmission line, in particular to a special conductor lifting device for a 220KV horizontal double bundle conductor, comprising a lead screw seat which can be fixed on a high voltage transmission tower, wherein a pair of mutually matched lead screw and nut is arranged on the upper seat of the lead screw seat, the nut can be rotated by operating a handle, and the lead screw can move up and down under the action of the nut; and the lower end of the lead screw is connected with a section of bearing pull rod, the lower end of the bearing pull rod is connected with a lifting board, the lifting board is horizontally connected with a lifting hook bracket, and a pair of lifting hooks for hooking the double bundle conductor is symmetrically arranged at two ends of the lifting hook bracket. The device has simple structure and convenient carrying and installation; and in the operating process, the operating personnel can operate the conductor up and down through a pedal, thereby being convenient for overhauling operation.

Description

technical field [0001] The invention relates to a maintenance tool for high-voltage transmission lines, in particular to a special wire lifter for 220 kV horizontal double-split conductors. Background technique [0002] In the prior art, there is no special tool for the installation of the horizontal double-split conductor in the 220 kV line. At present, the combination of the load-bearing rod (rope), the screw tightening tool and the wire hook is mainly used in China to complete the high-voltage line. Maintenance work. This method mainly has the following disadvantages: [0003] 1. Various tools are not a complete set of devices. On the one hand, there will be a mismatch between the components, on the other hand, there will be too many connectors, the connection and assembly process is cumbersome, and the safety and reliability of use will also be reduced; [0004] 2. Some connecting parts are large in size and heavy in weight, making it inconvenient to use and carry. ...

AI Technical Summary

Problems solved by technology

[0003] 1. Various tools are not a complete set of devices. On the one hand, there will be a mismatch between the components, on the other hand, there will be too many connectors, the connection and assembly process is cumbersome, and the safety and reliability of use will also be reduced;

[0004] 2. Some connecting parts are large in size and heavy in weight, making it inconvenient to use and carry

[0005] 3. The bearing rod (rope) does not have a convenient device for maintenance personnel to go up and down the wires. The personnel generally go up and down the wires along the insulators, but most of the existing lines have promoted the use of composite insulators, and it is forbidden to go up and down the wires along the composite insulators. This makes maintenance work difficult
