Extra-high voltage power transmission line strain insulator string in-out operation connecting device

Abstract

The invention discloses an extra-high voltage power transmission line strain insulator string in-out operation connecting device which comprises a fixing base, a fixing base is fixedly installed at the top of the fixing base, a climbing rod is fixedly installed at the top of the fixing base, and a fixing frame is installed on the outer side of the climbing rod. The top and the bottom of the fixingframe are fixedly connected with the tops of the fixed clamping blocks through a plurality of bolts respectively, and the top of one clamping block is rotationally connected with a fixed clamping block through a movable pin. According to the scheme, through mutual cooperation of the multiple climbing mechanisms, the climbing mechanisms slide on the climbing rods, the insulators are conveniently driven to be adjusted in horizontal height, and through installation of the sliding columns, the first hinge seats are driven by the sliding grooves to move up and down on the second hinge seats; and the climbing blocks can quickly slide up and down under the action of the crawler belt in cooperation with the connecting plate while sliding, so that the danger of high-altitude operation of workers is reduced, and the mounting stability of the insulator is improved.

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
