Description
Technical field
The present invention relates to power maintenance tools, and in particular to a kind of safety climbing ladder.
Background technology
In recent years, constantly accelerate along with China Power developing steps, China Power Grids are also rapidly developed, network system
Working voltage grade is continuously improved, and network size also constantly expands, and the whole nation has formd Northeast China Power Grid, North China Power Telecommunication Network, Central China
Power grid, East China Power Grid, the large area power grid of Northwest Grid and south electric network 6 transprovincially, and basically formed complete length away from
From power transmission electric network rack.Chinese intelligent grid pace of construction is accelerated, and extra-high voltage grid engineering progress is smooth.1000 kilovolts of Jin Dong
South-Nanyang-Jingmen UHVAC demonstration project passes through national acceptance, and it is no longer " experiment " to indicate extra-high voltage
" demonstration " stage.In October, 2011, Wan electricity Dong send Huainan to Shanghai ultra-high voltage AC transmission demonstration project to obtain national development to change
Leather committee checks and approves, and becomes the national Article 2 after southeast Shanxi-Jingmen power transmission engineering and is approved the ultra-high voltage AC transmission project built.
The strong intelligent grid of China enters the all-round construction stage within 2011, is connect in demonstration project, electric vehicle charging and conversion electric facility, new energy
It receives, Intelligent resident electricity utilization etc. is carried forward vigorously.
Old-fashioned electric pole cat ladder non-operating personnel's climbing in order to prevent in domestic electrical reticulation design, so designed that partly outstanding set
Meter, i.e., it is about 2.5 meters to 3 meters high apart from ground, it needs to build Mobile ladder stand temporarily when climbing, service personnel rides over the body of rod and fixes
The lower section of hanging ladder, in order to prevent back skating must also have special messenger to help and keep.Such as Chinese invention patent CN200720148158.9, the patent
It is proposed a kind of transmission line pole tower ascent protecting device, which prevents service personnel when climbing shaft tower because various factors interferes
And personal falling accident occurs, this mode requires operating personnel that must transport interim staircase using working truck and reach operation
Scene, takes to be placed to below electric pole from vehicle and is also required to manually shoulder fortune temporarily, and entirely climbs process and special messenger is needed to help
It keeps, it is time-consuming, laborious, take a lot of work.Since temporary ladder is not fixedly connected with electric pole original cat ladder, there is also certain security risks.
Invention content
The present invention provides a kind of safety climbing ladder, and solution needs to climb electric pole by temporary ladder in the prior art, and
The problem of temporary ladder is not fixedly connected with electric pole original cat ladder, and there is also certain security risks, specific technical solution is as follows：
A kind of safety climbing ladder, including fixed firm banking, the first annulus, the second annulus and overturning on utility poles are climbed
Ladder, the firm banking are three groups, and interval is identical to be laterally distributed on electric wire club body, the firm banking end of both sides and the
One annulus is fixedly connected, and intermediate firm banking end is rotatablely connected with overturning cat ladder side, the other side of the overturning cat ladder
It is fixedly connected with the second annulus, is spaced isometric between the width and firm banking of the overturning cat ladder, the overturning cat ladder is set on one side
There is protective plate.
Further, the protective plate is the cambered surface for being bonded electric pole backwards to the side of overturning cat ladder.
Further, first annulus and the second annulus are equipped with the identical through-hole of size.
Further, the protective plate width and overturning cat ladder are of same size.
Further, every group of quantity of the firm banking is 2.
It should be noted that since overturning cat ladder is arranged in the lower section of former cat ladder, under normal circumstances, overturning cat ladder side
Second annulus can be locked with the first annulus by chain lock, at this time due to the effect of protective plate, can not form climbing interface, when making
Used time, left-hand thread cat ladder can be overturn along horizontal direction, left-hand thread electric pole other one side, to original cat ladder become one
A plane, and form continuous climbing interface with original cat ladder.
Advantageous effect：
The present invention provides a kind of safety climbing ladder, and overturning cat ladder can be realized continuous climbing surface and disconnected and climbed with flip horizontal
Face, need not be by means of assisting cat ladder, personnel personnel convenient to overhaul to also improve safety while maintenance.
Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
Obtain other attached drawings according to these attached drawings.
Fig. 1 is that can hide electric power safety cat ladder vertical view one；
Fig. 2 is that can hide electric power safety cat ladder vertical view two；
Fig. 3 is the first annulus and the second annulus schematic diagram.
Specific implementation mode
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in the embodiment of the present invention
Technical solution is clearly and completely described, it is clear that described embodiments are some of the embodiments of the present invention, rather than complete
The embodiment in portion.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
