Description
Technical field
The utility model relates to a kind of escape device, especially relates to a kind of controlled friction-type fast escaping device for high building that is applicable to the high building indicator of trapped personnel escape that faces a danger.
Background technology
Along with skyscraper increases; the safe escape problem of skyscraper inhabitation personnel under crisis situation (for example fire, earthquake) becomes increasingly conspicuous, and it will be very important for the life danger that reduces high building inhabitation crowd that a kind of quick escape equipment of high building indicator of trapped personnel is provided.So-called escape device for high-rise buildings belongs to lifesaving appliance, mainly solves the high-rise life saving problem, promptly when needed can for the survivor fast, the equipment of safe escape dangerous situation, it is a help line.At present, the equipment that can be used for the high building personnel escape is a lot, mainly be divided into following three kinds: a kind of is slide formula escape device, be divided into vertical step ladder (for example metal extension ladder, rope ladder etc.) and spiral slide (for example steel tank, plastic channel, the soft slide of inflation (water) etc.), the security of this escape device is not high, falling speed as slide is uncontrollable, the slide length restriction escape altitude.Second kind is damp slow falling device escape device, drives the rotatable parts Compressed Gas or the liquid of descending lifeline by survivor's body weight pulling rope, and the resistance of generation slows down survivor's sinking speed, mechanism's more complicated of this escape device descending lifeline.The third is a gear friction-type descending lifeline escape device, produce rubbing action by the slow brake pad that falls in rope drive reducing gear running and the friction wheel hub, utilize centrifugal principle or brake principle control rotating speed, can guarantee that the user keeps the slow ground of reducing to of certain speed, but the descending lifeline of this escape device separates with the survivor, easily cause the survivor to hang on balcony or the roof, make the survivor can't regulate and control sinking speed, can cause survivor's psychology panic.
Summary of the invention
The purpose of this utility model is the weak point that overcomes in the prior art, and a kind of simple in structure, dependable performance, low-cost controlled friction-type fast escaping device for high building are provided.
For achieving the above object, the technical solution of the utility model: it by the friction descending lifeline and be set on the friction descending lifeline in the escape steel wire rope constitute, the friction descending lifeline comprises that order is located at left and right sides plate middle fixed friction wheel, sliding friction wheel and directive wheel, the escape steel wire rope surrounds on fixed friction wheel, sliding friction wheel and the directive wheel successively, forms the friction circular arc of 270 degree steel wire ropes and friction pulley; The bottom of left and right sides plate is provided with two shifting levers that contact with directive wheel, and shifting lever is provided with the survivor and spurs handgrip.
One end of described escape steel wire rope is provided with the clasp of being convenient to fix; Open the square opening of fixed friction wheel and a fixing bar shaped chute of sliding friction wheel and directive wheel on the plate of the described left and right sides; Be equipped with on described two shifting levers it is articulated in lever pin on the plate of the left and right sides; Described friction pulley, sliding friction wheel, directive wheel and two shifting lever equidimensions are arranged between the plate of the left and right sides.
The beneficial effects of the utility model: the operation principle novelty, mentality of designing is ingenious, decoration structure features simple design, application conditions mobility strong.Only promptly constitute descending lifeline and escape device with surplus 10 simple parts, and realized that frictional force is controlled, for the high building indicator of trapped personnel that faces a danger provides safe and reliable quick survival equipment, have in light weight, size is little, cost is low, using method is simple, can many people use and reuse, be convenient to the standing advantage such as deposit in family and public place.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a friction descending lifeline structure side view of the present utility model.
Among the figure: the 1-steel wire rope of escaping, 2-friction pulley, 3-directive wheel, 4-handgrip, 5-shifting lever, 6-sliding friction wheel, 7-left plate, 8-right plate, 9-lever pin.
The specific embodiment
The utility model will be further described below in conjunction with embodiment in the accompanying drawing:
Fig. 1 is shown in Figure 2, two side plates 7 about being fixed on, friction pulley 2 in the middle of 8, slidably friction pulley 6, directive wheel 3 constitutes a friction descending lifeline with two shifting levers that contact with directive wheel 35, the living steel wire rope of escaping 1 that has clasp holds the friction pulley 2 that is fixed in the friction descending lifeline successively, slidably friction pulley 6 and directive wheel 3, form the friction circular arc of 270 degree steel wire ropes and friction pulley, escape steel wire rope 1 surrounds fixed friction wheel 2 from top to bottom successively, sliding friction wheel 6 and directive wheel 3, about 90 degree of circular arc cornerite on fixed friction wheel 2, about 180 degree of circular arc cornerite are drawn the friction descending lifeline by directive wheel 3 then on sliding friction wheel 6.Escape steel wire rope 1 usefulness intensity enough aircraft cable manufacturings, friction pulley with coefficient of friction greater than more than 0.25 and the good metal material manufacturing of wearability.Two shifting levers 5 that contact with directive wheel 3 are the bottom that splayed is located at left plate 7 and right plate 8, lever pin 9 hinged securement are passed through in left and right sides plate 7 in its middle part, on 8, left and right sides plate 7, open the square opening of fixed friction wheel 2 and a fixing bar shaped chute of sliding friction wheel 6 and directive wheel 3 on 8, friction pulley 2, sliding friction wheel 6, directive wheel 3 and two shifting lever 5 equidimensions are arranged in left and right sides plate 7, between 8, friction pulley 2 is fixed in the square opening, sliding friction wheel 6 and directive wheel 3 are loaded in the bar shaped chute side by side, two shifting lever 5 symmetries are located at directive wheel 3 belows, sliding position variation with sliding friction wheel 6 and directive wheel 3 is swung, shifting lever 5 is connected with descending lifeline handle 4, survivor's pull handle 4 can drive shifting lever 5 and upwards promote friction pulley and be adjacent to mutually, makes the survivor hold descending lifeline and slides.
