Abstract

The new model discloses an electric maintenance ladder, which comprises a maintenance ladder body. At least two fixed hooks are arranged at the front end of the maintenance ladder body. The fixed hooks are hingedly connected with the maintenance ladder body. It is composed of ring blocks, one end of the movable ring block is hinged with the fixed ring block, and the other end is connected with the fixed ring block and the maintenance ladder body pin, and the length of the movable ring block is 1/4-1/3 of the length of the fixed ring block. This new model is easy to operate. In overhead maintenance, the front end of the maintenance ladder can be conveniently and reliably connected to the support by fixing hooks and rings, effectively preventing the maintenance ladder from slipping and falling. The traditional manpower anti-skid is eliminated, which improves the construction safety and saves manpower.

Description

electric maintenance ladder

technical field

The invention relates to an electric maintenance ladder, which belongs to the field of electric maintenance equipment.

Background technique

In electric power maintenance, it is often necessary to overhaul the electrical equipment and power supply lines located at a higher position. The commonly used climbing tool is the maintenance ladder. The traditional maintenance ladder mainly depends on the friction between the maintenance ladder itself and the ground and the relying objects. However, the anti-slip effect of this kind is extremely unsatisfactory. The maintenance ladder often slips and causes the operator to be injured. Therefore, in actual use, someone often needs to support the ladder on the ground to prevent slipping, but the anti-slip effect of this operation is still not good. It is ideal, but also increases the labor intensity of the operator and reduces the maintenance efficiency.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned disadvantages and provide an electric maintenance ladder.

To achieve the above object, the present invention is achieved through the following technical solutions:

An electric maintenance ladder, comprising a maintenance ladder body, at least two fixing shackles are arranged at the front end of the maintenance ladder body, and the fixing shackles are hingedly connected with the maintenance ladder body, and the fixing hook is a closed ring, and the fixed ring block One end of the movable ring block is hingedly connected with the fixed ring block, and the other end is connected with the fixed ring block and the maintenance ladder body pin, and the length of the movable ring block is 1/4-1/3 of the length of the fixed ring block.

The movable ring block is a rigid material.

The movable ring block is made of elastic wear-resistant material.

The new type is easy to operate. In the overhead maintenance, the front end of the maintenance ladder can be conveniently and reliably connected with the support by fixing the hook and ring, which can effectively prevent the maintenance ladder from slipping and fall. The traditional manpower anti-skid is eliminated, which improves the construction safety and saves manpower.

Description of drawings

Figure 1 is a schematic diagram of the new structure.

Detailed ways

As shown in Figure 1, an electric maintenance ladder includes a maintenance ladder body 1, at least two fixing shackles are arranged at the front end of the maintenance ladder body 1, the fixing shackles are hingedly connected with the maintenance ladder body 1, and the fixing shackles are hinged to the maintenance ladder body 1. The hook is an airtight ring, consisting of a fixed ring block 2 and a movable ring block 3, wherein one end of the movable ring block 3 is hingedly connected with the fixed ring block 2, and the other end is connected with a pin connection with the fixed ring block 2 and the maintenance ladder body 1, wherein the movable ring block 3 lengths are 1/4-1/3 of the fixed ring block 2 lengths.
