Abstract

The present invention relates to a kind of insulating ladder, comprise double ladder main body, it is characterized in that: a side of described double ladder main body is provided with a retractable support lever, the opposite side of described double ladder main body is provided with a connection cord in order to bind. The present invention can facilitate maintainer at once to answer the bind ladder on ground, has avoided staff because can not find rope temporarily, and has ignored ladder bind on framework; And can more provide a strong point to ladder, and form leg-of-mutton support, avoid ladder too high and rock, and because ladder opening angle is too large, and the more difficult problem of staircase.

Description

A kind of insulating ladder
Technical field
The present invention relates to a kind of insulating ladder, be applied to substation equipment maintenance and repair.
Background technology
Existing insulation double ladder, movable being fixed together in one end by two yi shaped ladders, the rope connection that has a restriction to open amplitude at the middle part of these two ladders (is opened to limit ladder, and operating personnel slides into), in the time that operating personnel works on ladder, ladder needs special messenger to help.
In actual service work, chevron shaped insulating ladder is for working on the frameworks such as PT, the CT of 220Kv, 35Kv, arrester, capacitor. And the double ladder of generally growing any has four or five meters long. When staff is in the time working, have larger rocking, and the angle of opening due to long any ladder is larger, the side that the staff of staircase often can only hold the ladder, so maintainer is at upper and lower ladder and work and can rock, produce unsafe hidden danger on ladder. Therefore are, objects that the present invention studies for the problems referred to above.
Summary of the invention
In view of the deficiencies in the prior art, the object of the present invention is to provide a kind of insulating ladder, contribute to solve existing insulation and shave the uneasy congruent problem that uses.
Technical program of the present invention lies in:
A kind of insulating ladder, comprises double ladder main body, it is characterized in that: a side of described double ladder main body is provided with a retractable support lever, and the opposite side of described double ladder main body is provided with a connection cord in order to bind.
Wherein, the lower end of described retractable support lever is provided with a base.
Described retractable support lever comprises by the upper and lower connecting rod being slidably connected and forming, and two connecting rods run through fixing by lock-screw.
The invention has the advantages that: the present invention can facilitate maintainer at once to answer the bind ladder on ground, has avoided staff because can not find rope temporarily, and has ignored ladder bind on framework; And can more provide a strong point to ladder, and form leg-of-mutton support, avoid ladder too high and rock, and because ladder opening angle is too large, and the more difficult problem of staircase.
Brief description of the drawings
Fig. 1 embodiment of the present invention perspective view.
Detailed description of the invention
For above-mentioned feature and advantage of the present invention can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
With reference to figure 1, the present invention relates to a kind of insulating ladder, comprise double ladder main body 1, a side of described double ladder main body is provided with a retractable support lever 2, and the opposite side of described double ladder main body is provided with a connection cord 3 in order to bind.
The lower end of above-mentioned retractable support lever is provided with a base 4.
Above-mentioned retractable support lever comprises by the upper and lower connecting rod being slidably connected and forming, and two connecting rods run through fixing by lock-screw.
In implementation process, add and can regulate rope in order to bind ladder and framework according to the height of framework by a side of framework at chevron shaped insulating ladder, this rope, except facilitating any position of bind at ladder, has also designed buckle on similar safety belt, makes rope colligation easily and dismounting.
Add in addition the telescopic supporting rod of an adjustable length at opposite side, the base of ladder supports and forms triangle stable support structure like this. To these two kinds of improvement of ladder, except making ladder easily and very firmly firm with framework, can also improve the adherence properties of ladder. Make service work safer.
The foregoing is only preferred embodiment of the present invention, all equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
