An insulator truck

Abstract

The invention belongs to the field of auxiliary transport devices, in particular to an insulator transport vehicle. The insulator transport vehicle of the present invention can be switched between two states to meet the needs of transporting insulators of different lengths. When transporting large insulators with large mass and long length, the length of the body can be extended to support the insulators better. , increase the number of support points, ensure the safety of the handling process, and prevent peak insulators from being damaged; when handling shorter insulators, the body can be turned over to form a multi-layer structure, and a larger number of insulators can be transported at one time. The volume of the body is reduced and it is more flexible Convenient, by flexibly switching the state of the body, the transportation of two types of insulators, long and short, can be completed with one tool. The structure and control method of the insulator transport vehicle are simple and flexible, low in cost, and the insulators are fixed effectively, which can effectively protect the insulators and improve the performance of the insulators. Handling efficiency.

Description

technical field [0001] The invention belongs to the field of auxiliary transport devices, in particular to an insulator transport vehicle. Background technique [0002] Insulators are one of the basic structures of transmission lines. Generally, they are required to have high insulation capacity and anti-creeping function. Therefore, they usually require a large surface roughness. The structure is generally a columnar structure composed of multi-layer insulating sheets. With the increase of grid voltage and the improvement of the safety requirements of the entire grid, the volume of insulators on high-voltage or ultra-high-voltage lines has become very large, especially in the following key nodes or transformers, and the insulators are sometimes several meters long. Often made of ceramic material, the overall mass is heavy. [0003] Due to the long length of large insulators and they cannot withstand excessive bumping or bending, when transporting long insulators, it is nec...

AI Technical Summary

Problems solved by technology

[0003] Due to the long length of large insulators and they cannot withstand excessive bumping or bending, when transporting long insulators, it is necessary to use a larger insulator truck for handling, otherwise the insulators will easily break if the two ends hang down. Larger insulator trucks are inconvenient for handling smaller insulators, and the number of large insulators is only a small number. Therefore, it is not economical to design and produce large-size insulator trucks, and the existing trucks are in use. Most of them are in point contact with the supporting surface of the vehicle, which makes it easy to roll and slide during the transportation process, or additional fixing tools including rope holders are required for fixing, which increases additional disassembly and assembly work, making the entire power grid operate in the middle, requiring a lot of power consumption. Time-consuming and labor-intensive transfer and disassembly of insulators reduces the efficiency of the power grid and increases the difficulty of the work
