Embodiment Construction

[0011] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings.

[0012] refer to figure 1 , the present invention relates to an insulating ladder, comprising a ladder main body 1, one side of the ladder main body is provided with a telescopic support rod 2, and the other side of the ladder main body is provided with a Connect the rope 3.

[0013] A base 4 is provided at the lower end of the telescopic support rod.

[0014] The above-mentioned telescopic support rod is composed of upper and lower connecting rods which are slidably connected, and the two connecting rods are penetrated and fixed by locking screws.

[0015] During the implementation process, a rope that can be adjusted according to the height of the frame is added to the side of the herringbone insulating ladder to bind the ladder and the frame. In addition to...

Abstract

The invention relates to an insulating ladder. The insulating ladder comprises a herringbone ladder main body; the insulating ladder is characterized in that a telescopic support rod is arranged at one side of the herringbone ladder main body, while a connecting rope for tying is arranged at the other side of the herringbone ladder main body. The insulating ladder is convenient for a maintainer to tie up the ladder any time anywhere and the working personnel cannot neglect to tie up the ladder to a framework due to the fact that a rope cannot be found temporarily; in addition, a supporting point is provided for the ladder and triangular support is formed, and therefore, the problems that the ladder shakes as being arranged too high and that the ladder is difficult to support with hands due to too large stretching angle are avoided.

Description

technical field [0001] The invention relates to an insulating ladder, which is applied to substation maintenance. Background technique [0002] Existing insulated herringbone ladders are fixed together by one end of two straight ladders. There is a rope that limits the opening range in the middle of the two ladders (to limit the opening of the ladders, and the operator slide to), when the operator is working on the ladder, the ladder needs to be supported by a special person. [0003] In the actual maintenance work, herringbone-shaped insulating ladders are used to work on 220Kv and 35Kv PTs, CTs, arresters, capacitors and other structures. The general longer herringbone ladder is four or five meters long. When the staff is working, there will be relatively large shaking, and because the opening angle of the longer ladder is relatively large, the staff who help the ladder can only hold one side of the ladder, so the maintenance personnel are going up and down the ladder an...
