The utility model provides a pair of steel pipe pole activity cat ladder adopts the sectional type design, and when not using, it is fixed on the last ladder to make the descending stair overturn, increases the height apart from ground, and the installation simultaneously, need not carried to the potential safety hazard of having avoided the climbing of non - maintainer to bring, has improved work efficiency, has saved the maintenance cost.
Description
Technical field
The utility model relates to high voltage line maintenance equipment technical field, particularly relates to a kind of steel pipe pole adjustable ladder.
Background technology
When high voltage line maintenance, maintainer uses cat ladder to carry out maintenance of ascending a height usually, and existing cat ladder is generally directly be fixed on high-voltage wire pole, and the distance on the distance ground, lower end of this cat ladder is lower, general personnel can directly climb on electric pole by cat ladder, there is potential safety hazard.Adopt the cat ladder be separated with electric pole, all need first to install cat ladder, reduce the efficiency of maintenance during each use, in addition, the volume of cat ladder is comparatively large, there is transport difficult, increases cost of transportation, add the cost of maintenance.
Utility model content
Technical problem to be solved in the utility model is: in order to overcome deficiency of the prior art, the utility model provides a kind of steel pipe pole adjustable ladder, when preventing circuit normal operating condition, people by mistake climbing pole tower causes getting an electric shock, avoid non-maintainer and climb the potential safety hazard brought, improve operating efficiency, save maintenance cost.
The utility model solves the technical scheme that its technical problem will adopt: a kind of steel pipe pole adjustable ladder, comprise setting upper ladder on utility poles and descending stair, described terraced lower end and described descending stair upper end are rotationally connected, when not using, descending stair and upper ladder are side by side and be fixedly connected with, during use, descending stair is vertically flipped an angle from upper ladder and take off, descending stair is connected up and down with upper ladder.Descending stair and upper ladder are rotationally connected, when not using by special crane bar descending stair upset got on on ladder fixing, add the distance on the distance from bottom ground of whole cat ladder, prevent the climbing of non-maintainer, avoid potential safety hazard; By sectional design, do not need to transport cat ladder back and forth, decrease cost of transportation, simple to operation.
Concrete, the angle ranging from 180 °.Overturning 180 ° can make ladder be connected with descending stair straight line, facilitates maintainer to climb.
Further, in order to realize descending stair upset get on after fixing, described descending stair lower end is provided with hook.Fixed by hook and upper ladder, fixing simple and convenient, easily operate.
Concrete, in order to improve the reliability that upper ladder is connected with descending stair, described hook is two.
Further, the side near described electric pole after described descending stair overturns is provided with some first otic placodes, and described electric pole is provided with second otic placode corresponding with described first otic placode, and described first otic placode and described second otic placode removably connect.After descending stair overturns, upper end is only had to be connected with upper ladder, the lower end of descending stair and the main body of descending stair are all in free state, in order to ensure the steadiness of descending stair, be fixedly connected with electric pole after descending stair is overturn, avoiding maintainer when climbing because descending stair instability is fallen from descending stair, reducing the security risk of operation.
Further, when described descending stair upset is got on arranged side by side with upper ladder, the distance on upper ladder and descending stair least significant end distance ground is 2.3 meters to 3.0 meters.In order to prevent non-maintainer from can take off descending stair, will keep certain height in the descending stair perigee distance ground overturn after getting on, stretch out one's hand to reach be advisable with the people of general height.
Concrete, when described descending stair upset is got on arranged side by side with upper ladder, the distance on upper ladder and descending stair least significant end distance ground is 2.5 meters.
Further, the bearing of trend of described upper ladder and the vertical direction of described electric pole have certain angle, and described angular range is 0 ° to 30 °.Conveniently maintainer's climbing, increase comfort level when climbing and safety, certain angle of inclination is there is between cat ladder entirety and electric pole, the size at angle of inclination can be chosen according to the height of the concrete electric pole used, it is larger that highly higher electric pole angle can be chosen, and highly low electric pole angle can be chosen smaller.
Concrete, the angle of the bearing of trend of described upper ladder and the vertical direction of described electric pole is 0 °, 5 °, 15 ° or 30 °.
The beneficial effects of the utility model are: a kind of steel pipe pole adjustable ladder that the utility model provides, adopt sectional design, when not using, descending stair is turned on ladder fixing, increase the height on distance ground, when preventing circuit normal operating condition, people by mistake climbing pole tower causes getting an electric shock, and avoids non-maintainer and climbs the potential safety hazard brought, simultaneously, do not need carrying and installation, improve operating efficiency, save maintenance cost.
