Description
Technical field
This utility model relates to power maintenance tool, is specifically related to a kind of back-buckling type concrete bar cat ladder.
Background technology
In recent years, constantly accelerate along with China Power developing steps, China Power Grids is also developed rapidly, network system working voltage grade improves constantly, network size the most constantly expands, the whole nation has defined Northeast China Power Grid, North China Power Telecommunication Network, Central China Power Grid, East China Power Grid, Northwest Grid and south electric network 6 large area electrical network transprovincially, and has basically formed complete long distance powedr transmission Net Frame of Electric Network.China's intelligent grid pace of construction is accelerated, and extra-high voltage grid engineering progress is smooth.1000 kilovolts of southeast Shanxi-Nanyang-Jingmen UHVAC demonstration projects pass through national acceptance, indicate that extra-high voltage is the most no longer " test " and " demonstration " stage.In October, 2011, Wan electricity Dong send Huainan to Shanghai ultra-high voltage AC transmission demonstration project to obtain National Development and Reform Commission and checks and approves, and becomes whole nation Article 2 after the power transmission engineering of southeast Shanxi Jingmen and is approved the ultra-high voltage AC transmission project built.Within 2011, Chinese strong intelligent grid enters the all-round construction stage, carries forward vigorously at aspects such as demonstration project, electric automobile charging and conversion electric facility, new forms of energy receiving, Intelligent resident electricity utilizations.
In domestic electrical reticulation design, old-fashioned concrete bar cat ladder is in order to prevent non-operating personnel from climbing, so designed that half outstanding design, i.e. distance ground is high about 2.5 meters to 3 meters, need to build Mobile ladder stand during climbing temporarily, maintainer rides over the body of rod and fixes the lower section of hanging ladder, keeps to prevent back skating from special messenger must also be had to hold up.Such as Chinese utility model patent CN200720148158.9, this patent proposes a kind of transmission line pole tower ascent protecting device, this device prevents maintainer from person falling accident occurring because various factors disturbs when climbing shaft tower, this mode just requires that operating personnel must use working truck to transport interim staircase and arrive operation field, interim taking from vehicle is placed to below electric pole be also required to manually shoulder fortune, and whole climbing process needs special messenger to hold up keeps, time-consuming, laborious, take a lot of work.It not fixing connection due to temporary ladder cat ladder former with concrete bar, there is also certain security risk.
Utility model content
This utility model provides a kind of back-buckling type concrete bar cat ladder, solves to need by temporary ladder to climb concrete bar cat ladder in prior art, and temporary ladder cat ladder former with concrete bar is not fixing connection, the problem that there is also certain security risk, and concrete technical scheme is as follows:
A kind of back-buckling type concrete bar cat ladder, including fixing bar, first gangbar, second gangbar, left-hand thread cat ladder, clamping body and round bar, described fixing bar and round bar symmetry be fixed on concrete bar, and the end of described fixing bar is rotationally connected with the first gangbar, described first gangbar is rotationally connected with the side of left-hand thread cat ladder, opposite side and second gangbar of described left-hand thread cat ladder are rotationally connected, and the other end of described second gangbar is connected with clamping body, and described clamping body positive and negative all can engage with round bar.
Further, the length of described first, second gangbar is more than the radius of concrete bar.
Further, described clamping body is connected and composed by two semicircular ring side by side, and the junction between semicircular ring is connected with described second gangbar end, and the opening direction of two semicircular ring is all towards the second gangbar.
Further, the first gangbar connection that described left-hand thread cat ladder side is parallel with several, the second gangbar connection that opposite side is parallel with several.
Further, between described first gangbar, between the second gangbar, it is provided with bracing piece.
It should be noted that, owing to left-hand thread cat ladder is arranged on the lower section of former cat ladder, under normal circumstances, left-hand thread cat ladder is buckled in the opposite of former cat ladder by clamping body, is locked by chain lock, when deployed, left-hand thread cat ladder can overturn along horizontal direction, left-hand thread is in the other one side of concrete bar, thus becomes a plane with original cat ladder, and forms continuous print climbing interface with original cat ladder.
Beneficial effect:
This utility model provides a kind of back-buckling type concrete bar cat ladder, and left-hand thread cat ladder can be with flip horizontal, it is achieved climbing surface and disconnection climbing surface continuously, it is not necessary to by means of auxiliary cat ladder, also improve safety while facilitating maintainer personnel maintenance.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
