Description
Technical field
The present invention relates to a kind of high building fire self-rescue escape device.
Background technology
In the fire, people often are confined in ground such as window, balcony, can't escape the inferno, and the rescue because other lifesaving appliances such as fire fighting truck do not arrive in the very nick of time, perhaps fire spreading is too fast, and the method for this class danger that causes selecting among flurried jumping out of the building is escaped.This escape mode will be brought life danger or permanent disability, if the original place is waited to rescue then might be choked smoked by dense smoke, poison gas that fire produces and cause death, so, the key how in the of short duration time, to utilize easy escape device to save oneself and will be escaping from high building on fire.
Quickening along with China's modernization paces, spreading fast of economic globalization, increasing high buildings and large mansions begin to rise sheer from level ground in the city, the product of this symbols of modernity brings to us and has also brought a lot of very important hidden danger outside the convenience, so the escaping from high building on fire device also becomes the problem that people more and more pay close attention to.In today that people's living standard day by day improves, the stability of the security of escape device, speed, whereabouts just becomes the standard of purchase.Existing professional fire-fighting escape device is divided into two kinds substantially, a kind of is to utilize the principle of hydraulic system to make slow descending device, be equipped with the flowing velocity of structures such as hoist engine, rope, support by confined liquid, the speed that the people is fallen remains in certain scope, reaches slow purpose of falling.Another kind is to utilize mechanisms such as mechanical driving device, built-in gear, by rim brake, and rope, devices such as speed changer, the decrease speed of control survivor in the escape process landed slowly, finally reaches the purpose of escape.But above professional device complex structure, rescue cost height can not be suitable for self-help escape, can't popularize.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to use, high-building self-help escape device of can be good at solving security, speed and stability.
For reaching above purpose, the present invention takes following technical scheme to be achieved:
A kind of high building fire self-rescue escape device, comprise cylinder, a locating rack that is fixed on the tower window exterior wall that twines rope, connect a main shaft on the described locating rack, the main shaft middle part is provided with a brake wheel, in the brake wheel both sides, be symmetrical arranged the left and right sleeve that can on main shaft, roll, the two ends cover of described cylinder connects firmly with the end of left and right sleeve away from brake wheel respectively, it is characterized in that the left and right sleeve of described brake wheel and brake wheel both sides is provided with centrifugal braking mechanism.
In the such scheme, described centrifugal braking mechanism comprises that order is sleeved on six pin rings, spring, the tripod ring on the sleeve of brake wheel both sides from inside to outside, and wherein tripod ring and sleeve connect firmly, at uniform three band-type brakes of brake wheel periphery, each band-type brake is connected with brake wheel both sides six pin rings by the key ring in addition; Described tripod ring is connected with three weights, is connected with six pin rings by a connecting rod on the arm of each weight.
Described cylinder is that the center is divided into left and right sides two parts with the brake wheel, according to positive and negative direction respectively around last rope so that be used alternatingly.Also connect a sub-frame that is positioned at the cylinder below on the described locating rack, have the gap of two symmetries on this sub-frame, the rope that two parts twine on the cylinder passes this two gaps respectively, in order to prevent the staggered influence of two ropes.
Advantage of the present invention is, the speed that adopts easy centrifugal braking mechanism that the people is fallen remains in certain scope, reach the purpose of safe escape, cylinder adopts the opposite two parts rope that twines, after wherein a rope is delivered to ground with people's safety, people still to be rescued upstairs can utilize another root rope around full cylinder to fall, on one side second people falls, first rope can rap around on the cylinder gradually along with the rotation of cylinder.This apparatus structure is simple, and the cost of saving oneself is low, and is safe and reliable, is applicable to the self-help escape of average family fire in high buildings.

The specific embodiment
As Fig. 1 to shown in Figure 4, the weight-driven that high building fire self-rescue escape device of the present invention is descended by human body, whole lifesaving appliance is to utilize locating rack 9 to be fixed on the wall in the outside of tower window, locating rack 9 adopts the hexagonal thread connection with main shaft 4.Along cylinder 10 outer walls according to both forward and reverse directions respectively around last rope, sub-frame 1 gap of cylinder below is passed at the two ends of rope respectively, prevents the staggered influence of two ropes.Cylinder 10 combines as a whole with both sides cover 8, and cover 8 utilizes jackscrew to be fixed on the sleeve 5 two ends external diameters.At the main shaft middle part brake wheel 15 being set is connected with main shaft 4, in brake wheel 15 left and right sides, symmetry cover upper bush 5 is installed in six pin rings 11, spring 13, tripod ring 6 above the sleeve 5 of brake wheel both sides by order from inside to outside then, and wherein tripod ring 6 connects firmly with sleeve 5.Main shaft 4, locating rack 9, sub-frame 1 can not be affected when cylinder 10 is subjected to the rotation of human body gravity like this, and sleeve 5 rotates around main shaft 4 with the rotation of cylinder 10 together with the parts that all are fixed on the sleeve.Three band-type brakes 16 are distributed on brake wheel 15 peripheries, and adopt pivot pin to be fastened on three ring ears of brake wheel both sides six pin rings 11 by right two the key rings 14 of a first from left.Adopt pivot pin to be connected on the ring ear of tripod ring 6 by screw weight 7, adopt pin to be connected on the arm of weight at connecting rod 12 1 ends simultaneously, the other end also adopts pin to be connected on remaining three ring ears of six pin rings 11.When the people is dragging the rope whereabouts, human body gravity drives cylinder 10 and rotates, band-type brake 16 on the rotating band moving sleeve 5 of cylinder 10 and the parts tripod ring 6 on the sleeve 5, spring 13, six pin rings 11 and the brake wheel 15 rotates, rotating the centrifugal force that produces opens the weight 7 that is fixed on the tripod ring 6, weight 7 opens pulling connecting rod 12, connecting rod 12 pullings six pin rings 11, six pin rings, 11 pulling band-type brakes 16 are held brake wheel 15 tightly, spring 13 compression this moment, band-type brake 16 positions are determined after the pulling force balance between the elastic force of spring 13 and weight 7, the connecting rod 12.This spring 13 should make band-type brake 16 position suitables through debugging when equipment dispatches from the factory; Owing to the increase of the frictional force between band-type brake 16 and the brake wheel 15 along with rotating speed increases, certainly will slow down the speed that whole lifesaving tube descends, reach minimum until speed.Otherwise when the initial velocity of lifesaving tube was excessive, the centrifugal force that weight 7 is subjected to also can increase thereupon, and the power of holding tightly of band-type brake 16 can increase, and the rotating speed of the lifesaving tube that slows down reduces the speed that human body falls.Whole rotation process medi-spring 13 pressurizeds guarantee that band-type brake 16 continues to hold tightly.Both forward and reverse directions can be used alternatingly around two parts rope on this device cylinder, after wherein a rope is delivered to ground with people's safety, and people still to be rescued upstairs
Can utilize another root rope around full cylinder to fall, on one side second people falls, first rope can rap around to along with the rotation of cylinder on the cylinder gradually, so alternately, and until everyone ground of arriving safe and sound.
