Description
Technical field
The utility model relates to cat ladder, a kind of for the detachable cat ladder of communication tower specifically.
Background technology
Single-pipe tower is because its floor space is little, cost performance is high and the advantage more attractive in appearance than traditional angle steel tower is widely used in the fields such as communication, electric power and municipal high pole street lamp.Convenient for installation, maintenance, single-pipe tower also needs to configure corresponding cat ladder, and cat ladder has two kinds of built-in cat ladder and external cat ladders, and built-in cat ladder is arranged at pipe tower inside, and staff climbs in tower.But the less working space that cannot hold cat ladder and personnel cannot be provided of internal diameter of some single-pipe tower, therefore needs cat ladder to be arranged at single-pipe tower outside, forms external cat ladder.Common external cat ladder is made up of the pin nail that is fixed on the ladder of single-pipe tower outer wall and be fixed on ladder.The tower body peripheral space that this external cat ladder occupies is large, affects attractive in appearance; And unrelated person can arbitrarily climb, both dangerous, easily cause again equipment stolen.
Existing Patents in prior art, as the patent No. " 201210331079.7 ", name is called " link-type is hidden cat ladder ", this patent content is: comprise the cat ladder supervisor of being fixed on communication Ji Ta, in cat ladder supervisor's short transverse, be equally spaced provided with multiple cat ladders foot-operated, cat ladder is foot-operated hinged with cat ladder supervisor, on cat ladder supervisor, has foot-operated storage tank, the foot-operated corresponding foot-operated storage tank of each cat ladder; Cat ladder is foot-operated to be responsible for hinged one end with cat ladder and to be provided with extension, this extension is connected with driving the foot-operated actuating unit launching or receive of cat ladder, actuating unit comprises and is arranged at the lifting motion bar in cat ladder supervisor and is arranged at the connecting plate between lifting motion bar and extension, and connecting rod is converted to the elevating movement of lifting motion bar the foot-operated expansion of cat ladder, draws motion in;
Although this technical scheme can solve climbing problem; But still existing problems, first, each cat ladder needs independent foot-operated storage tank, so just destroy cat ladder supervisor's structure, greatly reduced supervisor's bulk strength, actuating unit has been set, complex structure, fault rate is high, and difficulty of processing is large, cost is high, and the time is long, inefficiency, and at every turn can only be for a people, workman's maintenance difficulty is strengthened, and cat ladder is foot-operated in outside exposed, run into the situation of bad weather, be easy to be corroded by wind and rainwater, have for a long time safety problem.
