Abstract
The invention relates to a linkage-type hidden ladder comprising a ladder main tube fixed on a communication base tower. A plurality of ladder steps are provided at intervals on a height direction of the ladder main tube. The ladder steps are hinged with the ladder main tube. Step accommodation slots are provided on the ladder main tube. Each ladder step is corresponding to a step accommodation slot. One ends of the ladder steps hinged with the ladder main tube are provided with extending parts, wherein the extending parts are connected with a power mechanism driving the ladder steps to unfold or fold. The power mechanism comprises an elevation movable rod arranged in the ladder main pipe and a connection plate arranged between the elevation movable rod and the extending parts. With a linkage, elevation movements of the elevation movable rod are converted into unfolding ands folding movements of the ladder steps. The appearance of the ladder provided by the invention is good, and the ladder can prevent climbing of unauthorized personnel.
Description
Technical field
The present invention relates to a kind of cat ladder for the Ji Ta that communicates.
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 field such as communication, electric power and municipal high pole street lamp.In order to installation, maintenance is convenient, single-pipe tower also needs to configure corresponding cat ladder, and cat ladder has built-in cat ladder and external cat ladder two kinds, and it is inner that built-in cat ladder is arranged at pipe tower, and staff climbs in tower.But the less working space that cannot hold cat ladder and cannot provide personnel of the 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 followed closely by the ladder and the pin be fixed on ladder that are fixed on single-pipe tower outer wall and is formed.The tower body peripheral space that this external cat ladder occupies is large, affects attractive in appearance; And unrelated person can arbitrarily be climbed, both dangerous, easily cause 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 the Linkage-type hidden ladder that unrelated person is arbitrarily climbed can be prevented.
Linkage-type hidden ladder, comprise the cat ladder supervisor of being fixed on communication Ji Ta, the short transverse of cat ladder supervisor is equally spaced provided with multiple cat ladder and rides, cat ladder is foot-operated to be responsible for hinged with cat ladder, cat ladder supervisor has foot-operated storage tank, the foot-operated corresponding foot-operated storage tank of each cat ladder;
Cat ladder is ridden and is responsible for hinged one end with cat ladder and is provided with extension, this extension is ridden with drive cat ladder the actuating unit launched or receive and is connected, actuating unit comprises the lifting motion bar be arranged in cat ladder supervisor and the connecting plate be arranged between lifting motion bar and extension, and the elevating movement of lifting motion bar is converted to the foot-operated expansion of cat ladder, draws motion in by connecting rod.
Further, lifting motion bar is fixed with minor axis, and minor axis and connecting plate are hinged, and the extension that the other end of connecting plate is ridden by rivet and cat ladder is riveted.
Further, the middle part of minor axis is welded with lifting motion bar, a two ends hinged connecting plate respectively of minor axis.
Further, the two ends of connecting plate form the portion of expanding respectively, the portion of expanding of connecting plate and minor axis or rivet interlacement.
Further, the free end that cat ladder is ridden is provided with Anti skid stop dog, and Anti skid stop dog protrudes from cat ladder and rides.
Further, the foot-operated both sides of cat ladder are respectively equipped with a pair outward extending sleeve, and be inserted with foot-operated rotating shaft in sleeve, foot-operated rotating shaft runs through cat ladder supervisor, this foot-operated rotating shaft is ridden as cat ladder and cat ladder be responsible between hinge.
Further, the top of cat ladder supervisor is provided with end cap, end cap is fixed with the guide pin bushing of hollow, and lifting motion bar inserts and moves up and down along guide pin bushing, lifting motion bar and guide pin bushing matched in clearance.
Further, the bottom of lifting motion bar is provided with and drives its driving mechanism moved up or down, and driving mechanism is placed in cat ladder supervisor.This driving mechanism can be the handle manually promoted, and also can be motor and the transmission mechanism power transmission of motor output being extremely elevated motion bar.
Further, the expansion direction that neighbouring cat ladder is ridden is contrary.
Technical conceive of the present invention is: in cat ladder supervisor, arrange lifting motion bar, and the elevating movement of lifting motion bar is delivered to the foot-operated extension of cat ladder by connecting plate, and cat ladder is ridden and is fulcrum with foot-operated rotating shaft, rotates under the active force of connecting plate.
When being elevated motion bar and moving downward, connecting plate is ridden cat ladder and is applied downward active force, and cat ladder is ridden and upwards screwed in corresponding foot-operated storage tank for fulcrum with foot-operated rotating shaft, now rides as receiving state.
When being elevated motion bar and moving upward, connecting plate rides applying active force upwards to cat ladder, and cat ladder is ridden and screwed out corresponding foot-operated storage tank with foot-operated rotating shaft downwards for fulcrum, now rides as deployed condition.
When needing climbing, drive lifting motion bar to move upward by driving mechanism, cat ladder can be launched, be convenient to climbing.When not needing climbing, drive lifting motion bar to move downward cat ladder can be made to receive by driving mechanism, during storage, appearance is only a cat ladder supervisor, specious.And driving mechanism is positioned at cat ladder supervisor, only has user can enter and utilize driving mechanism, unrelated person can be avoided arbitrarily to climb.
The present invention has specious, can avoid the advantage that unrelated person is arbitrarily climbed.

Detailed description of the invention
With reference to accompanying drawing, further illustrate the present invention:
Linkage-type hidden ladder, comprise the cat ladder supervisor 1 of being fixed on communication Ji Ta, the short transverse of cat ladder supervisor 1 is equally spaced provided with multiple cat ladder foot-operated 3, cat ladder foot-operated 3 and cat ladder are responsible for 1 hinged, cat ladder supervisor 1 has foot-operated storage tank 11, the corresponding foot-operated storage tank 11 of each cat ladder foot-operated 3;
Cat ladder is ridden 3 and is responsible for 1 hinged one end with cat ladder and is provided with extension 33, this extension 33 is connected with the actuating unit driving cat ladder to ride 3 expansion or storage, actuating unit comprises the lifting motion bar 2 be arranged in cat ladder supervisor 1 and the connecting plate 4 be arranged between lifting motion bar 2 and extension 33, and the elevating movement of lifting motion bar 2 is converted to expansion, the gathering motion that cat ladder rides 3 by connecting rod.
Lifting motion bar 2 is fixed with minor axis 21, and minor axis 21 and connecting plate 4 are hinged, and the extension 33 that the other end of connecting plate 4 rides 3 by rivet 6 and cat ladder is riveted.
