Abstract
The invention relates to a public plate safety device, in particular to a lifting type tread-preventing device. The device comprises fixed supports, clamps, inner telescopic rods and a pair of handrail rods, wherein multiple inner telescopic rods are installed on each handrail rod and hinged to the fixed supports, the fixed supports and the clamps are fixed to the top of a stairway, the handrail rods are installed parallel to the stairway, the handrail rods and the inner telescopic rods are overturned to be attached to the top of the stairway when not used, and the handrail rods are clamped by the clamps. The device can be stored on the top of the stairway, the free height and appearance of the stairway are not affected, and the handrail rods can provide leverage points for escape crowd to main body balance after descending; meanwhile, the two handrail rods are combined with stair railings after descending, and crowd decentralization can be guided, so that people can be evacuated in order.
Description
Technical field
The present invention relates to a kind of public place safety device, be specially Liftable type and prevent trampling device.
Background technology
Existing patent " handle type stair special for preventing trampling accidents " (application number: 201110270393.4) describe a kind of equipment that in case of emergency can prevent the accident of trampling, it is provided with three hanger bar along stair longitudinal direction in the bottom of stair bench, every bar hanger bar arranges handle, the vertical distance that each handle and the ladder below it walk is 1.7-1.9 rice, when pedestrian is about to fall, the handle of top can be caught, thus avoid the accident of trampling caused because falling to occur.This technical disadvantages is mainly manifested in: always (1) its design is fixedly hanging on above stair at ordinary times, the vertical distance that handle walks with the ladder below it is 1.7-1.9 rice, can impact crowd under nonemergency is current, not only affect headway and the outward appearance of stair passage, and change the 26S Proteasome Structure and Function of building; (2) handle is positioned near the escape crowd crown, and at regular intervals between handle, can not ensure that unbalanced people can catch handle, can affect that facility is anti-tramples effect, due to its defect in nonemergency design, is difficult to apply.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of can receive anti-ly trample device, do not affect the current of crowd under normal circumstances.Concrete technical scheme is:
Liftable type is anti-tramples device, comprise fixed bearing, fixture, interior expansion link and a pair handrail, described each handrail is provided with multiple interior expansion link, described interior expansion link is hinged on fixed bearing, fixed bearing and fixture are fixed on the top, top in stair road, a pair handrail along the parallel installation in stair road, when handrail and interior expansion link do not use, upset is attached to the top, top in stair road, lives handrail by holder.
Described interior expansion link is made up of Multi section bar, and there is packing ring two pole junctions bottom respectively, are provided with spring between packing ring.
Liftable type provided by the invention is anti-tramples device, and can be accommodated in the top, top in stair road at ordinary times, can not affect headway and the outward appearance of stair, can be connected with fire alarm, a key triggers; After handrail declines can for escape crowd provide maintain balance borrow force, meanwhile, after two groups of handrails decline and stair railing combine, can crowd decentralization be guided, withdraw in order.Handrail height adjustable, can adjust the falling head of interior expansion link and handrail according to different occasion personnel situation, applied widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is side-looking structure chart in emergency circumstances of the present invention.
Detailed description of the invention
The accompanying drawings specific embodiment of the invention, as depicted in figs. 1 and 2, Liftable type is anti-tramples device, comprise fixed bearing 2, fixture 4, interior expansion link 3 and a pair handrail 1, described each handrail 1 is provided with multiple interior expansion link 3, described interior expansion link 3 is hinged on fixed bearing 2, fixed bearing 2 and fixture 4 are fixed on the top, top in stair road, a pair handrail 1 is along the parallel installation in stair road, when handrail 1 and interior expansion link 3 do not use, upset is attached to the top, top in stair road, clamps handrail 1 by fixture 4.
Interior expansion link 3 is made up of Multi section bar, and there is packing ring two pole junctions bottom respectively, be provided with spring, prevent whereabouts from injuring crowd by a crashing object between packing ring.
Under nonemergency, interior expansion link 3 shrinks, and the top, top being attached to stair road packed up by handrail 1 and interior expansion link 3, and fixes handrail 1 by fixture; In emergency circumstances, operator's trigger switch, fixture 4 is opened, and handrail 1 and interior expansion link 3 are turned to plumbness under gravity, it is 1.0-1.5 rice position that interior expansion link 3 is elongated to apart from below stair vertical distance under gravity, and escape crowd can hold handrail 1 and prevent from falling.
In order to prevent interior expansion link 3 and handrail 1 from injuring escape crowd by a crashing object in decline process, at the interface of interior expansion link last two joints, packing ring and spring are set to reduce decrease speed.
