Insulator replacement device

Abstract

The invention discloses an insulator replacement device which comprises a clamp apparatus and a length regulation mechanism. The clamp apparatus comprises a first clamping plate and a second clamping plate which are fixedly connected; the first clamping plate and the second clamping plate are enclosed to form a cylindrical cavity; a first accommodating groove is formed on the upper end face of the first clamping plate; a second accommodating groove is formed on the upper end face of the second clamping plate; a first regulating ring is arranged in a sliding mode in the first accommodating groove; a second regulating ring is arranged in a sliding mode in the second accommodating groove; the center lines of arc holes interact with the center lines of the ring-shaped accommodating grooves; through slots are arranged on the side end faces of the first clamping plate and the second clamping plate; extension directions of the through slots point to the central axis of the cylindrical cavity; the upper ends of the through slots are communicated with the ring-shaped accommodating grooves; limiting pillars are arranged in a sliding mode in the through slots; limiting pins are vertically arranged at the upper end faces of the limiting pillars; the upper ends of the limiting pins extend out of the arc holes. According to the insulator replacement device disclosed by the invention, by regulating the positions of the arc holes, sliding of the limiting pillars in the through slots is implemented; and the insulator replacement device can be used for the replacement work of all types of suspended insulator strings in a substation.

Description

technical field [0001] The invention belongs to the technical field of electric facility maintenance, and in particular relates to an insulator replacement device. Background technique [0002] The amount of suspension insulator strings in the substation is huge, and the suspension insulator strings are in the open environment for a long time. Under the influence of environmental factors such as wind, sun and sun, the internal stress of the insulators will be unbalanced, resulting in low zero value of the insulators and even structural damage. The damage defects of suspension insulator strings in substations are increasing day by day. At present, there is no special replacement tool suitable for the suspension insulator strings in the station. When replacing the suspension insulator strings in the station, it can only be replaced by the traditional method, that is, the hand hoist is used to pull the wires and clamps, so that the suspension insulator strings are in the In th...

Problems solved by technology

[0005] When the above two structures are in use, the size of the jig head in contact with the steel cap of the insulator is fixed, but the size of the steel caps produced by different manufacturers, different models, and different batches is different, and the chuck head is too small when used. If it is too large or too large, it is impossible to guarantee the fit between the fixture head and the steel cap, so it is necessary to make fixture heads of different sizes for matching, which not only has the problem of high cost, but also increases the time and risk of high-altitude operations due to the inconvenience of disassembly and assembly
