Abstract

The invention discloses an electric power overhaul ladder which comprises an overhaul ladder body. At least two fixed looped links are arranged at the front end of the overhaul ladder body and are in hinged connection with the overhaul ladder body. The fixed looped links are of closed ring shape. Each fixed looped link is formed by a fixed ring block and a movable ring block, wherein one end of the movable ring block is in hinged connection with the fixed ring block, and the other end of the movable ring block is in pin connection with the fixed ring block and the overhaul ladder body. The length of the movable ring block is one fourth to one third that of the fixed ring block. The electric power overhaul ladder is easy and convenient to operate. When the electric power overhaul ladder is lifted for overhauling, the front end of the overhaul ladder traditionally leans against a supporting object, and besides, the overhaul ladder can be conveniently, quickly and reliably hung and buckled with the supporting object through the fixed looped links. Consequently, the overhaul ladder is effectively prevented from slipping and falling, a traditional manual slip prevention operation is eliminated, construction safety is improved, and manpower is saved.

Description

A kind of electric power overhaul ladder
Technical field
The present invention relates to a kind of electric power overhaul ladder, belong to electric power overhaul apparatus field.
Background technology
In electric power overhaul, often need to overhaul being positioned at electric equipment and the supply line of higher position, conventional ascending tool is maintenance ladder, traditional maintenance ladder in use, the main frictional force of maintenance ladder self and ground and dependence thing that relies on is come anti-skidding, but this kind of skidproof effect is extremely undesirable, often occur that maintenance ladder slips and causes operating personnel injured, therefore toward contact, need to have people on ground, to face ladder in actual use helps anti-skidding, but it is still undesirable so to operate skidproof effect, the operating personnel's that simultaneously also strengthen labour intensity, reduced overhaul efficiency.
Summary of the invention
The object of the invention is just to overcome above-mentioned deficiency, and a kind of electric power overhaul ladder is provided.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of electric power overhaul ladder, comprise the terraced body of maintenance, the terraced body front end of described maintenance is provided with at least two fixedly shackles, described fixedly shackle is hinged with the terraced body of maintenance, described stay hook is airtight annular, retainer ring piece and loose collar piece, consists of, and wherein loose collar piece one end and retainer ring piece are hinged, the other end is with retainer ring piece and overhaul terraced body pin and be connected, and wherein loose collar block length is 1/4-1/3 of retainer ring block length.
Loose collar piece is rigid.
Loose collar piece is elastic wear-resisting material.
This Novel operating is easy, make somebody a mere figurehead maintenance be, overhaul that terraced front end is except traditional and supporter rely on also can be convenient buckled and be connected with supporter maintenance is terraced by fixing shackle reliably, effectively prevent that overhauling ladder slips, can remove traditional manpower from anti-skidding, when having improved working security, also save manpower.
Accompanying drawing explanation
Fig. 1 is new structure schematic diagram.
Embodiment
As shown in Figure 1, a kind of electric power overhaul ladder, comprise the terraced body 1 of maintenance, terraced body 1 front end of described maintenance is provided with at least two fixedly shackles, and described fixedly shackle is hinged with the terraced body 1 of maintenance, and described stay hook is airtight annular, by retainer ring piece 2 and loose collar piece 3, formed, wherein loose collar piece 3 one end and retainer ring piece 2 are hinged, the other end and retainer ring piece 2 and overhaul terraced body 1 pin and be connected, and wherein loose collar piece 3 length are 1/4-1/3 of retainer ring piece 2 length.
