A bottle holder for insulators with a preset arch

Abstract

An arched insulator bottle rack that can be preset includes horizontal steel pipes for installing the bottle racks. Four horizontal steel pipes are used for installing the bottle racks to form a horizontal steel pipe group. Set the collar member for the arch, and set the fasteners for the arch at the joints between the two ends of the horizontal steel pipes for the bottle rack installation in the middle of the horizontal steel pipe group and the collar member for the arch. The middle position of the steel pipe group is provided with a longitudinal support for installing the bottle holder. In the present invention, the horizontal steel pipe group is formed into a preset arch shape from the horizontal and vertical directions by using the ring member for the preset arch, the longitudinal bracket for installing the bottle holder, and the fastener for the preset arch. The degree of pre-bending can be set according to different weights, so that the bottle holder can be realized. When the insulator is pressed on the bottle holder in series, the space reserved for pre-bending allows the operator to put the ball head from the gap between the bowl heads. pull out.

Description

technical field [0001] The invention relates to a force-bearing tool, in particular to a bottle holder for an insulator with a preset arch shape used for transferring the force on the insulator during installation and maintenance of power transmission and transformation lines. Background technique [0002] At present, a kind of insulator bottle holder (referred to as bottle holder) is often used in the installation and maintenance of power transmission and transformation lines in power systems. Power tools, when used, the bottle holder plays a supporting role for the insulator, so that the insulator is always kept in a straight line on the bottle holder under the action of its own weight, and the bottle holder provides support for the insulator during power maintenance. Working conditions such as pending maintenance and replacement of porcelain bottle strings [0003] And the bottle holders under the prior art include insulating bottle holders, linear bottle holders, strain...

AI Technical Summary

Problems solved by technology

The bottle holder can realize that when the insulators are pressed on the bottle holder in series, the space reserved for pre-bending allows the operator to pull the ball head out of the gap between the bowl heads, and the pre-bending structure also solves the problem of existing The straight line structure of the bottle holder under the technology makes the insulator's own weight press down, the bottle holder bends down, and the distance between the insulators will increase when the insulator is tightened.
