Abstract

The utility model relates to a portable insulator replacing tool. The portable insulator replacing tool comprises an upper hook which is used for being connected with a cross arm. A lifting device is arranged at the lower part of the upper hook. A ladder is arranged on the lifting end of the lifting device. A lower hook which is used for being connected with a cable is arranged at the lower part of the ladder. According to the utility model, the tool has the advantages of simple and reasonable structure and convenient implementation and promotion; when the tool is used, the upper hook is hung on the cross arm, and the lower hook is hung on the cable which needs insulator replacing; an operator climbs on the ladder; through the lifting of the lifting device, the distance between the cross arm and the cable is shortened, and the insulator is not under stress; the operator completes insulator replacing on the ladder; the problems that the insulator is easily trampled and the operator easily falls off, which are caused due to the fact that the operator has to step on the insulator in the past, are avoided; and the portable insulator replacing tool is labor-saving and time-saving, can protect the insulator and can improve the safety coefficient.

Description

A convenient tool for replacing insulators

technical field

The utility model relates to a tool used in the electric power industry, in particular to a convenient tool for replacing insulators.

Background technique

Insulators are special insulation controls that can play an important role in overhead transmission lines. It is used to support and fix the busbar and live conductors, and to make enough distance and insulation between live conductors or between conductors and the earth, and has sufficient electrical insulation strength and moisture resistance. In the actual use process, the insulator will be damaged due to long-term use or external factors. In order to ensure the normal supply of electricity, it is required to replace the insulator in time. Now when insulators are replaced, people step on the insulators directly, which is easy to damage the insulators, and the insulators are slippery, and people are easy to slip and fall from the insulators, which poses a great safety hazard.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a convenient insulator replacement tool which is simple in structure, easy to use, saves trouble and labor, can not only protect the insulator but also improve the safety factor.

The purpose of this utility model is achieved as follows: a convenient tool for replacing insulators, which includes an upper hook used to connect with the cross arm, a lifting device is provided at the lower part of the upper hook, and a climbing ladder is provided at the lifting end of the lifting device. The lower part is provided with a lower hook for connecting with cables.

The lifting device adopts a manual hoist, and the upper end of the ladder is connected with the lifting end of the cable of the manual hoist.

Both the upper hook and the lower hook are insulating hooks.

The ladder is composed of a main rod connected with a lifting device and cross braces evenly arranged on both sides of the main rod.

The utility model has the following positive effects: the utility model comprises an upper hook, a lifting device, a climbing ladder and a lower hook which are sequentially connected from top to bottom, the structure is simple and reasonable, and is convenient for implementation and popularization; On the cross arm, hang the lower hook on the cable to replace the insulator. The operator climbs onto the ladder and lifts it through the lifting device, thereby shortening the distance between the cross arm and the cable, so that the insulator is not stressed. The operator is on the ladder. Complete the replacement of the insulator, thereby avoiding the problems that the traditional people have to step on the insulator to easily damage and drop the insulator, which has the advantages of saving trouble and labor, not only protecting the insulator, but also improving the safety factor.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described further.

Example 1

As shown in Figure 1, a convenient tool for replacing insulators, it includes an upper hook 1 used to connect with the cross arm, the lower part of the upper hook 1 is provided with a lifting device 2, and the lifting end of the lifting device 2 is provided with a climbing ladder 3, the climbing ladder The bottom of 3 is provided with the lower hook 4 that is used for being connected with cable.

The utility model comprises an upper hook, a lifting device, a climbing ladder and a lower hook sequentially connected from top to bottom. The structure is simple and reasonable, and is convenient for implementation and popularization; On the cable to replace the insulator, the operator climbs onto the ladder and lifts it through the lifting device, thereby shortening the distance between the cross arm and the cable, so that the insulator is not stressed, and the operator completes the replacement of the insulator on the ladder, thus avoiding the traditional The problem that people who want to step on the insulators are easy to step on the insulators and drop them, has the advantages of saving trouble and labor, not only protecting the insulators, but also improving the safety factor.

Example 2

As shown in Figure 1, a convenient tool for replacing insulators, it includes an upper hook 1 used to connect with the cross arm, the lower part of the upper hook 1 is provided with a lifting device 2, and the lifting end of the lifting device 2 is provided with a climbing ladder 3, the climbing ladder The bottom of 3 is provided with the lower hook 4 that is used for being connected with cable.

The lifting device 2 adopts a manual hoist, and the upper end of the ladder 3 is connected with the lifting end of the cable 5 of the lifting device 2 .

Both the upper hook 1 and the lower hook 4 are insulated hooks.

The ladder 3 is composed of a main rod connected with the lifting device 2 and cross braces evenly arranged on both sides of the main rod.

The utility model comprises an upper hook, a lifting device, a climbing ladder and a lower hook sequentially connected from top to bottom. The structure is simple and reasonable, and is convenient for implementation and popularization; On the cable to replace the insulator, the operator climbs onto the ladder and lifts it through the lifting device, thereby shortening the distance between the cross arm and the cable, so that the insulator is not stressed, and the operator completes the replacement of the insulator on the ladder, thereby avoiding the traditional The problem that people who want to step on the insulators are easy to step on the insulators and drop them, has the advantages of saving trouble and labor, not only protecting the insulators, but also improving the safety factor.
