Problems solved by technology

There are many types of spacers used on ultra-high voltage transmission lines, and there is no uniform replacement tool
At present, the spacer removal tool widely used by construction units has a simple structure but a single function. The maintenance personnel need to replace the disassembly tool many times during the operation, so that the maintenance personnel need to carry a large number of tools during maintenance, resulting in heavy loads and inconsistent working methods. , needs to be replaced according to one's own experience, and the operation efficiency is low

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, a power transmission line spacer replacement tool provided by the present invention includes a screw rod 1, a base body 2, a first jaw 3, a second jaw 5, a pressing block 6 and a guide rail 7, wherein the base body 2 is provided with a guide rail 7. The first jaw 3 and the second jaw 5 are slidably connected to the guide rail 7, the screw 1 is screwed to the base 2, and one end of the screw 1 is connected to the first jaw 3 and the second jaw. The pressing block 6 between the two jaws 5 is fixedly connected. The other end of the screw 1 is provided with a wrench 8 .

[0023] The screw 1 and the threaded hole on the base 2 form a screw pair, and the feeding movement is realized by the rotation of the wrench 8 .

[0024] Such as figure 2 As shown, the first jaw 3 and the second jaw 5 have the same structure, and the first ...

Abstract

The invention relates to a special tool for power maintenance, in particular to a transmission line spacer replacing tool. The tool comprises a screw, a base, a first clamping jaw, a second clamping jaw, a pressing block, and a guide rail. The guide rail is arranged on the base. The first clamping jaw and the second clamping jaw are connected in a sliding manner with the guide rail. The screw is in threaded connection with the base. One end of the screw is fixedly connected with the pressing block disposed between the first clamping jaw and the second clamping jaw. The transmission line spacer replacing tool of the invention is simple in structure, convenient, labor-saving, universal and portable.

Description

technical field [0001] The invention relates to a special tool for electric power maintenance, in particular to a tool for replacing a spacer bar of a power transmission line. Background technique [0002] At present, two, four or more split conductors are used for each phase conductor of long-distance and large-capacity EHV transmission lines. In order to keep the spacing between the split wire harnesses constant to meet the requirements of electrical performance and reduce the surface potential gradient, spacers are installed at a certain distance in the span. There are many types of spacers used on ultra-high voltage transmission lines, and there is no uniform replacement tool. At present, the spacer removal tool widely used by construction units has a simple structure but a single function. The maintenance personnel need to replace the disassembly tool many times during the operation, so that the maintenance personnel need to carry a large number of tools during mainten...
