A connecting device for connecting tension insulator strings in and out of UHV transmission lines

Abstract

The invention discloses a connection device for connecting in and out of tension insulator strings of UHV transmission lines. Frame, the top and the bottom of the fixed frame are respectively fixedly connected with the top of the fixed clamping block by several bolts, and the top of one of the clamping blocks is rotatably connected with a fixed clamping block through a movable pin. This scheme slides on the climbing rod through the mutual cooperation of several climbing mechanisms, which facilitates the adjustment of the horizontal height of the insulator. Through the installation of the sliding column, the first hinge seat is driven by the chute to move up and down the second hinge seat. Activities, while sliding, cooperate with the connecting plate to quickly make the climbing block slide up and down under the action of the crawler belt, reduce the danger of workers working at heights, and improve the stability of insulator installation.

Description

technical field [0001] The invention relates to the technical field of insulators, in particular to a connecting device for connecting tension insulator strings of UHV transmission lines. Background technique [0002] An insulator string refers to an assembly of two or more insulator elements combined to flexibly suspend conductors. The insulator string is a protective device with fixed and operational needs, which is used to suspend the wire and insulate the wire from the tower and the earth. The insulator strings used in transmission lines have different assembly forms due to the difference in tower structure, insulator structure, wire size, number of sub-wires per phase, and voltage level. However, it can be summarized into two categories: suspension insulator strings and tension insulator strings. [0003] 1) When installing insulators on high-voltage lines, most of them are installed manually. Operators are at risk when working at high altitudes. During the process of...

Problems solved by technology

[0005] The purpose of the present invention is to provide a connecting device for connecting in and out of tension insulator strings of UHV transmission lines to solve the problem that the traditional insulators on high-voltage lines are installed in the above-mentioned background technology. Most of the installation is done manually, and operators have certain risks when working at high altitudes. , in the process of high-altitude transportation of insulators, lack of concentration, it is easy to cause the center of gravity to be unstable and fall, and the equipment installed with insulation cannot be adjusted by sliding. During the installation process, bumps occur, causing damage to the insulator
