Description

Special tools for live replacement of rod insulators

technical field

The utility model relates to the field of electric power maintenance, in particular to a special tool for live replacement of rod-type insulators.

Background technique

Rod insulators are continuously used on transmission lines. As the operating time increases, rod insulators will have defects due to external or internal causes. Affecting the safe operation of the line, each rod porcelain insulator weighs tens of kilograms, and it is difficult to replace it. It is necessary to develop a new type of convenient and efficient live replacement tool for rod-type insulators of transmission lines. The special lifting method solves the problem of a single insulator with a large weight. problems, greatly reducing the labor intensity of high-altitude workers, and effectively improving the efficiency of live work.

Patent CN205016917U discloses a 660kV tension rod porcelain insulator maintenance device, including a support connecting rod, a locking device symmetrically arranged at both ends of the supporting connecting rod, a traction device for tightening the two locking devices, and a horizontal rail to prevent the entire device from rolling. Connecting frame; the locking device is fixedly connected to the supporting link through the hanging hole plate, one end of the hanging hole plate is fixedly connected to the supporting connecting rod, and the other end is fixedly connected to the locking device; the two locking devices need to be replaced The rod porcelain is locked on the steel cap of the adjacent rod porcelain. The contraction of the traction device makes the two locking devices shrink so that the rod porcelain to be replaced is loosened and can be disassembled, and the hook is hung on the adjacent On the fixed object, it prevents the whole device from turning over, which is convenient and labor-saving, reduces the workload and intensity of high-altitude operations, and reduces the replacement time of insulator rod porcelain. After the installation of the device, due to the multi-stage installation, the overall strength is insufficient, it is easy to deform when replacing heavy insulators, the positioning of the hoisting position is cumbersome, and the traction cylinder is too long.

Contents of the invention

The technical problem to be solved by the utility model is to provide a special tool for live replacement of rod-type insulators, which has high structural strength, easy transportation and installation, easy hoisting and positioning, long service life of the device, and is more suitable for replacement of larger insulators.

In order to achieve the above object, the utility model adopts the following technical solutions:

A special tool for live replacement of rod-type insulators, including a front card support and a rear card support, the lower part of the front card support is fixedly connected with a hydraulic tightening device, the hydraulic tightening device is bolted to the lower part of the rear card support through a connecting plate, and the upper part of the front card support It is fixedly connected with the hoisting beam, the upper part of the rear card support is fixedly linked with the support bar, the hoisting beam is connected with the support bar with bolts, a chute is provided on the hoisting beam, and a hoisting ring that can slide in the chute is provided on the chute, and the hoisting ring is made of Lock buckle limit.

A pulley or a suspension hook is arranged on the hoisting ring.

The locking buckle is slidingly connected with the lifting beam.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model has the advantages of safety and reliability, high structural strength, convenient transportation and installation, easy hoisting and positioning, long service life of the device, and is more suitable for replacement of larger insulators.
