Abstract
Fire escape device for high-rise buildings of the present utility model, is provided with the gearbox being with centrifugal friction pulley, two groups of steel wires that on cylinder, coil direction is contrary in coiling wire cylinders, continuously-running, improve escape speed, avoid when device idle running returns and need artificial hand to shake receipts, save time.Centrifugal friction principle is utilized to control human body decrease speed, thus realize human body dependence Gravitative Loads with the device of the decline of comparatively stable speed, back and forth use, can for the emergency machine formula escape device providing trapped personnel to leave desperate situation during high-rise building with fire disaster dangerous situation.
Description
Technical field
The utility model relates to fire escape device for high-rise buildings, is specifically related to one and utilizes centrifugal friction principle to control human body decrease speed, thus realizes human body dependence Gravitative Loads with the device of the decline of comparatively stable speed, back and forth use.Particularly a kind of meeting an urgent need for trapped personnel when high-rise building with fire disaster dangerous situation leaves the mechanical type escape device of desperate situation.
Background technology
China is a populous country, is to solve the demand such as inhabitation, office, hotel, food and drink, amusement, market, skyscraper continue to bring out stand in great numbers, densely distributed.Fire occurs often, although all kinds of building is all equipped with corresponding fire-fighting, emergency escape facility, as: extra exit, special escape elevator for subsequent use etc., but occur once fire dangerous situation, because personnel are numerous, escape anxious, the situation such as to fall over each other, fire can be there is occur and the time difference found, survivor is difficult to arrive public fire fighting device point at short notice, and be out of danger with the fastest speed, people often carry out in escape way in selector channel etc. because of panic and very easily trample, choked to death by dense smoke, killed by building collapsing, finally still can cause the personnel casualty accidents that cannot make up, so when high-rise building with fire disaster dangerous situation, can can trapped personnel utilize self-helping tool to withdraw desperate situation with the fastest speed be the key avoiding or reduce casualties, and domestic there is no comprehensively uses good personnel's lifesaving product at present, domestic from what found, in outer interrelated data document, we see by centrifugal friction principle control human body decrease speed, conventional fire escape device for high-rise buildings divides by the scope of application and mainly contains two kinds, one is applicable single disposable escape device, if the shortcoming place that to be personnel numerous everyone be equipped with a set of, use cost is high, be limited in scope, example as is known China Patent No. is 200620115364.5 utility model patents being called " safe escape device ".The escape device that a kind of place being applicable personnel are numerous uses, though can repeatedly back and forth use, but need artificial hand to shake receipts when idle running returns, waste time and energy and complex structure, example as is known China Patent No. is the utility model patent that 200420026186.X name is called " fire escape device for high-rise buildings ".
Summary of the invention
Technical problem to be solved in the utility model is, there is provided that a kind of structure is simple, speed be quick, the fire escape device for high-rise buildings of handling safety, good reliability, it can use in higher building, and the place that the personnel that are applicable to are more can back and forth use repeatedly.
The technical scheme solving the employing of its technical problem is: design a kind of fire escape device for high-rise buildings, comprise centrifugal friction wheel, axle, cylinder, gear train, internal gear, gear shaft group, cylinder, steel wire rope, shell, cylinder is fixed on drums inside, cylinder is fixed on enclosure, cylinder coils the two groups of steel wire ropes having direction contrary, cylinder end plate is welded with gear shaft group, gear shaft group is equipped with gear train respectively, axle is fixed on shell, cylinder, cylinder home position, for output shaft, axle is fixed with and turns to two groups of contrary centrifugal friction wheels, internal gear is fixedly installed in enclosure, two groups of steel wire ropes that coil direction is contrary on cylinder, cylinder end plate is welded with gear shaft group, gear shaft group is equipped with gear train respectively, axle is output shaft, axle is fixed with and turns to two groups of contrary centrifugal friction wheels, internal gear and shell are fixed, while steel wire rope release, inverted plate is in around steel wire rope and receives around state, driven gear axle group is rotated around internal gear simultaneously, make axle output shaft make speedup to rotate, final centrifugal friction wheel rotates, when the rotating speed of centrifugal friction wheel reaches centrifugal critical point speed, brake pad throws away, produce with cylinder inner wall and rub, axle speed is reduced, drum speed is finally made to reduce, control human body decrease speed, thus realize human body rely on Gravitative Loads decline with comparatively stable speed.After trapped personnel arrives safe and sound ground, while steel wire rope release, inverted plate is in around steel wire rope and receives around state, and final centrifugal friction wheel has rotated decelerating effect, thus reproduction back and forth uses repeatedly, and continuously-running, improves escape speed, save time.
Fire escape device for high-rise buildings of the present utility model, is provided with the gearbox being with centrifugal friction pulley, two groups of steel wires that on cylinder, coil direction is contrary in coiling wire cylinders, continuously-running, improve escape speed, avoid when device idle running returns and need artificial hand to shake receipts, save time.Centrifugal friction principle is utilized to control human body decrease speed, thus realize human body dependence Gravitative Loads with the device of the decline of comparatively stable speed, back and forth use, can for the emergency machine formula escape device providing trapped personnel to leave desperate situation during high-rise building with fire disaster dangerous situation.

Detailed description of the invention
As shown in the figure, fire escape device for high-rise buildings of the present utility model, comprise centrifugal friction wheel (1 and 2), axle (3), cylinder (4), gear train (5), internal gear (6), gear shaft group (7), cylinder (8), steel wire rope (9 and 10), shell (11), it is inner that cylinder (4) is fixed on cylinder (8), it is inner that cylinder (8) is fixed on shell (11), cylinder (8) above coils the two groups of steel wire ropes (9 and 10) having direction contrary, cylinder (8) end plate is welded with gear shaft group (7), gear shaft group (7) is equipped with gear train (5) respectively, axle (3) is fixed on shell (11), cylinder (8), cylinder (4) home position, for output shaft, axle (3) is fixed with and turns to two groups of contrary centrifugal frictions wheel (1 and 2), it is inner that internal gear (6) is fixedly installed in shell (11), while steel wire rope (10) discharges, inverted plate is in around steel wire rope (9) and receives around state, driven gear axle group (7) rotates around internal gear (6) simultaneously, make axle (3) output shaft make speedup to rotate, final centrifugal friction wheel (1) is rotated, when the rotating speed of centrifugal friction wheel (1) reaches centrifugal critical point speed, brake pad throws away, produce with cylinder (4) inwall and rub, axle (3) speed is reduced, cylinder (8) speed is finally made to reduce, control human body decrease speed, thus realize human body rely on Gravitative Loads decline with comparatively stable speed.After trapped personnel arrives safe and sound ground, while steel wire rope (9) discharges, inverted plate is in around steel wire rope (10) and receives around state, final centrifugal friction wheel (2) has rotated decelerating effect, thus reproduction back and forth uses repeatedly, continuously-running, improve escape speed, save time.
