Description
Technical field
The utility model relates to a kind of mechanical device that is applied to the skyscraper emergency escape.
Background technology
Along with increasing of city skyscraper, under the urgent accident, the research of the escape device of skyscraper extremely is necessary.And the existing emergency escape equipment that disposes for skyscraper mostly is that accessory device is many, and operation inconvenience, has a strong impact on survivor's successful escape probability.At above-mentioned situation, with low cost, high reliability, easy care, simple structure form etc. is main design philosophy, the author has designed a kind of passive escape apparatus.Described passive escape apparatus does not need external power source to drive, and by the moment of reaction that centrifugal force produces, sets up degenerative closed-loop system, realizes the maximum speed that the restriction survivor falls, and finishes safe soft landing.
Simultaneously, the device of many skyscraper emergency escapes also arranged in reading up the literature, can roughly be divided into following main several classes by the principle form that realizes: based on gear train, as a kind of novel speed limiting mechanism (number of patent application: 03202557.2) by a main shaft, internal tooth rotating disk and speed limit slide block are formed, but this speed limiting mechanism is all too complicated in whole mechanism, and can only but feel simply helpless for the escape problem of higher floor by delaying to quicken to realize survivor's escape unharmed; Based on damping buffering, escape device for high-rise buildings (number of patent application: 92110178.3) adopt the method for hydraulic damping to cushion decrease speed, make it to reach the purpose that keeps constant speed to descend, owing to adopt the mode of hydraulic circuit to form the damping of speed limit, make overall structure too complicated, and be not easy to I﹠ M; Based on centrifugal, as centrifugal governor and dual controlled multiplexing type steady stopping device (number of patent application: 200420041460.0) adopt at centrifugal jointed shaft place increase cam, reach the effect that speed limit is surely fallen, but, the method that this limiter of speed adopts cam to increase the brake-shoe braking moment descends because realizing speed stabilizing, to produce huge wearing and tearing to brake-shoe, and this mechanism form is not easy to repair maintenance.
Summary of the invention
The purpose of the utility model patent provides a kind of easy to operate, easy passive escape apparatus.
The purpose of the utility model patent is achieved in that
Form by speed increasing mechanism and speed limiting mechanism; Described speed increasing mechanism comprises first 2, pulley 3, ring gear 4 and external gear 6, first 2 by hanger 7 be fixed on pair of bearings supporting in the left end cap 1 on the hanger 7, but the pulley 3 of a lay winding wire ropes is installed on first 2, ring gear 4 is fixed on the right side of pulley 3, ring gear 4 and external gear 6 engagements that are installed on second 8; Described speed limiting mechanism comprises radiation wheel 9, steel ball 10 and second 8, the second 8 by hanger 7 be fixed on pair of bearings supporting in the right end cap 12 on the hanger 7, a radiation wheel 9 is installed on second 8, and steel ball 10 is stored in the groove of radiation wheel 9.
The utility model can also comprise:
1, have a through hole on the right end cap 12, the through hole is provided with stopper 11.
2, axle sleeve 5 is set on first 2.
The operation principle of the utility model patent is:
The survivor fixes with the steel wire rope that is wrapped on the pulley, jumps down from skyscraper.Pulley on the rope belt moving axis 1 rotates with the ring gear of fixing on it.Gear ring drives external gear, and drives the radiation wheel by the effect that key on the axle 2 connects, and then drives steel ball and carry out centrifugal motion.Centrifugal steel ball and hanger inner chamber mutual extrusion produce the enough big moment of reaction simultaneously under the effect of radiation wheel, realize the effect of this passive escape apparatus speed limit.Along with steel wire rope the reducing of pulley action radius, survivor's falling speed can corresponding decline, reaches safe soft landing effect.
The utility model is a kind of easy to operate, easy skyscraper emergency escape mechanical device, realizes survivor's the slow landing and the soft landing of safety, guarantees survivor's safe escape.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
For example the utility model is done more detailed description below in conjunction with accompanying drawing:
In conjunction with Fig. 1 and Fig. 2, passive escape apparatus mainly is made up of speed increasing mechanism and speed limiting mechanism.Described speed increasing mechanism comprises: first 2, and pulley 3, ring gear 4, axle sleeve 5,6, the second 8 of external gears.Wherein first 2 by hanger 7 be fixed on pair of bearings supporting in the left end cap 1 on the hanger 7, and it is spacing with axle sleeve 5, but first 2 by the pulley 3 of key connection by a lay winding wire ropes, wherein ring gear 4 is fixed on the right side of pulley 3, ring gear 4 and the transmission of external gear 6 by gear pair realization power are realized first 2 to second 8 speedup.Described speed limiting mechanism comprises: second 8, and radiation wheel 9, steel ball 10.Wherein second 8 by hanger 7 be fixed on pair of bearings supporting in the right end cap 12 on the hanger 7, and second 8 connects a radiation wheel 9 by key, and steel ball 10 is stored in the groove of radiation wheel 9, and seals with stopper 11.Can carry out the adjustment of decrease speed by the quantity of increase and decrease steel ball, reach the user demand of satisfying varying environment.
The concrete course of work is as described below:
The survivor fixes with the steel wire rope that is wrapped on the pulley 3, jumps down from skyscraper.Pulley 3 on steel wire rope drives first 2 rotates with the ring gear of fixing on it 4.Gear ring 4 drives external gear 6, and the effect that key connects on passing through second 8 drive radiation wheel 9, and then drive steel ball 10 carries out centrifugal motion.Centrifugal steel ball 10 and hanger 7 inner chamber mutual extrusion produce the enough big moment of reaction simultaneously under the effect of radiation wheel 9, realize the effect of this passive escape apparatus speed limit.Along with steel wire rope the reducing of pulley 3 operating radiuses, the corresponding falling speed of survivor is reduced, reach safe soft landing effect.Generally speaking, the speed that the survivor falls increases to relative maximal rate earlier, reaches poised state, then because steel wire rope acts on the minimizing of the effective radius of pulley, survivor's falling speed reduces accordingly, reaches the soft landing effect of speed limit and safety in whole escape process.
