Description
Technical field
The present invention relates to a kind of cat ladder for communication Ji Ta.
Background technology
Single-pipe tower is little because of its floor space, 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 it is inner that built-in cat ladder is arranged at the pipe tower, and the staff climbs in tower.But therefore the less working space that can't hold cat ladder and personnel can't be provided of the internal diameter of some single-pipe tower need to be arranged at cat ladder the single-pipe tower outside, forms the external cat ladder.Common external cat ladder is comprised of the ladder that is fixed on the single-pipe tower outer wall and the pin nail that is fixed on the ladder.The body of the tower peripheral space that this external cat ladder occupies is large, affects attractive in appearance; And unrelated person can arbitrarily climb, and is both dangerous, easily causes again equipment stolen.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of specious and can prevent unrelated person arbitrarily the link-type of climbing hide cat ladder.
Link-type is hidden cat ladder, comprise the cat ladder supervisor of being fixed on the communication Ji Ta, equally spaced be provided with a plurality of cat ladders on cat ladder supervisor's the short transverse foot-operated, cat ladder is foot-operated hinged with the cat ladder supervisor, has foot-operated storage tank on the cat ladder supervisor, the foot-operated corresponding foot-operated storage tank of each cat ladder;
The end that cat ladder is foot-operated and the cat ladder supervisor is hinged is provided with the extension, this extension is connected with the actuating unit that drives the foot-operated expansion of cat ladder or take in, actuating unit comprises and is arranged at the lifting motion bar in the cat ladder supervisor and is arranged at connecting plate between lifting motion bar and the extension, and connecting rod is converted to the elevating movement of lifting motion bar the foot-operated expansion of cat ladder, draws motion in.
Further, be fixed with minor axis on the lifting motion bar, minor axis and connecting plate are hinged, the extension riveted joint that the other end of connecting plate is ridden by rivet and cat ladder.
Further, the middle part of minor axis and the welding of lifting motion bar, the two ends of minor axis are a hinged connecting plate respectively.
Further, the two ends of connecting plate form respectively the section of expanding, and the section of expanding of connecting plate is connected with minor axis or rivet.
Further, the foot-operated free end of cat ladder is provided with Anti skid stop dog, and it is foot-operated that Anti skid stop dog protrudes from cat ladder.
Further, the foot-operated both sides of cat ladder are respectively equipped with a pair of outward extending sleeve, are inserted with foot-operated rotating shaft in the sleeve, and foot-operated rotating shaft runs through the cat ladder supervisor, and this foot-operated rotating shaft is as cat ladder is foot-operated between being responsible for cat ladder hinge.
Further, cat ladder supervisor's top is provided with end cap, is fixed with the guide pin bushing of hollow on the end cap, and the lifting motion bar inserts and moves up and down lifting motion bar and guide pin bushing matched in clearance along guide pin bushing.
Further, the bottom of lifting motion bar is provided with and drives its driving mechanism that moves up or down, and driving mechanism places in the cat ladder supervisor.This driving mechanism can be the handle that manually promotes, and also can be motor and with the transmission of power of the motor output transmission mechanism to the lifting motion bar.
Further, the foot-operated expansion direction of neighbouring cat ladder is opposite.
Technical conceive of the present invention is: in cat ladder supervisor the lifting motion bar is set, the elevating movement of lifting motion bar is delivered to the foot-operated extension of cat ladder by connecting plate, and cat ladder is foot-operated take foot-operated rotating shaft as fulcrum, rotate under the active force of connecting plate.
When the lifting motion bar moved downward, connecting plate was ridden cat ladder and is applied downward active force, and cat ladder is foot-operated to be screwed in the foot-operated storage tank of correspondence as fulcrum makes progress take foot-operated rotating shaft, and this moment is foot-operated to be receiving state.
When the lifting motion bar moved upward, connecting plate was to the foot-operated active force upwards that applies of cat ladder, and cat ladder is ridden take foot-operated rotating shaft as fulcrum and screwed out corresponding foot-operated storage tank downwards, and this moment is foot-operated to be deployed condition.
When needing climbing, drive the lifting motion bar by driving mechanism and move upward, cat ladder can be launched, be convenient to climbing.When not needing to climb, drive the lifting motion bar by driving mechanism and move downward cat ladder is taken in, appearance only is a cat ladder supervisor when taking in, and is specious.And driving mechanism is positioned at the cat ladder supervisor, only has the user can enter and utilize driving mechanism, can avoid unrelated person arbitrarily to climb.
The present invention has specious, can avoid the arbitrarily advantage of climbing of unrelated person.
