Problems solved by technology

Different conductors and different types of spacer bars produced by different hardware manufacturers are also diversified. At present, there are more than ten types of spacer bars for 500kV transmission lines. Each spacer bar is equipped with different installation tools and tools. cumbersome operation
[0003] At present, there are three kinds of disassembly and assembly tools for 500kV transmission line spacers (claw type, centering type, and sleeve type). These tools are all taken to the field at high altitude and are very heavy, which greatly increases the workload of the operators.
And the three kinds of spacer special tools currently used, it takes 12 to 15 minutes to install and remove a spacer

Embodiment Construction

[0024] Such as Figure 1~2 As shown, a special disassembly tool for spacers of 500kV transmission lines, including a cam wrench 1, a pull rod 3 and a light pin 5, one end of the pull rod 3 is hinged with the cam wrench 1 through a pin 2, and the pull rod 3 is set along the length direction Have a row of six jacks 3-1 that can cooperate with light pin 5.

[0025] In this embodiment, the cam wrench 1 is provided with two holes, both of which can cooperate with the pin 2 . In order to facilitate the operation of the light pin 5 and not easily lose it, the other end of the pull rod 3 is connected to one end of the light pin 5 through a chain 4 .

[0026] The utility model designs a cam wrench 1 and a pull rod 3 with adjustable porous positions, which can meet the disassembly and assembly needs of spacers of different models and sizes. Only one pair of special disassembly tools for 500kV transmission line spacers can replace the original variety of different tools. The special to...

Abstract

The invention relates to a special tool for a 500kV electric transmission line spacing bar and an application method thereof. The special tool comprises a cam wrench, a pull rod and an unthreaded pin, wherein one end of the pull rod is hinged to the cam wrench through a pin, the cam wrench is provided with a plurality of hole sites which can all be matched with the pin, the other end of the pull rod is connected with one end of the unthreaded pin through a chain, and the pull rod is provided with a row of inserting holes which can all be matched with the unthreaded pin in the length direction. The special tool has the advantages of universality, high efficiency, easy-to-master performance and the like, the hole sites are designed, the adjustable cam wrench and the pull rod can meet the assembling and disassembling needs of spacing bars of different models and different sizes, only one tool can replace various special tools originally, the tool can be carried portably and conveniently by installation personnel, the principle of lever and crowbar is mainly used, operation technologies and operation steps for assembling and disassembling the spacing bars are simplified, the working efficiency is greatly improved, the easy-to-master performance is achieved, the principle is simple, and training and using are easy.

Description

technical field [0001] The invention relates to a special disassembly and assembly tool for a 500kV transmission line spacer and a use method thereof. Background technique [0002] With the rapid development of power grid construction, the types of conductors used on 500kV transmission lines are diversified, and the cross-sectional areas of conductors are also increasing, from the initial 300, 400 to 500, 630 and even 800. Different conductors and different types of spacer bars produced by different hardware manufacturers are also diversified. At present, there are more than ten types of spacer bars for 500kV transmission lines. Each spacer bar is equipped with different installation tools and tools. The operation is cumbersome. [0003] At present, there are three kinds of disassembly and assembly tools for 500kV transmission line spacers (claw type, centering type, and sleeve type). This tool is all taken to the wild high altitude and is very heavy, which greatly increas...
