Abstract
The invention discloses a high building escape device with triple damping superimposed on each other. The high building escape device comprises a fixing frame, and is characterized in that a rope pulley main shaft capable of driving a liquid damping mechanism and a centrifugal friction mechanism is mounted at the middle of the fixing frame; a rope pulley is mounted at one end or two ends of the rope pulley main shaft through a unidirectional bearing; and a backup escape rope is wound on the rope pulley; and at the same time the escape device is also provided with a disc brake. According to the invention, the centrifugal escape device and the liquid damping escape device are used in cooperation, so the advantages of the two devices can be brought into reduplicate play, the shortcomings of the two devices are compensated, and the safety of escaping persons can be guaranteed practically. On the early stage of falling, the liquid damping action is mainly depended upon to play a cushioning effect, the whole falling process is a gradual acceleration and then stable uniform speed process, and with the trip damping superposing on each other in conjunction with the disc brake mechanism, the falling speed of the escaping persons are effectively controlled, and the safety of the escaping persons can be guaranteed practically, so that the high building escape device is very good in safety and adapts to the needs of different persons.
Description
Technical field:
The present invention relates to the high-rise life saving technical field, be specifically related to a kind of triple damping and mutually superpose to improve security and rational high-rise escape apparatus.
Background technology:
Along with the enhancing day by day of China's economic strength, urbanization process is maked rapid progress, high buildings and large mansions are also a feast for the eyes, towering standing upright.Although skyscraper has many advantages, when the disaster such as earthquake or fire occurs, the personnel that occupy high building are safe escape how, has been the significant problem faced at present.The fire disaster of the skyscraper occurred in all parts of the country caused any property loss and casualties in recent years, had caused paying close attention to of the whole society.
Occupy the personnel of high building when disaster occurs, mainly contain passive type and active two class escape modes.Passive escape mode is exactly to wait for the rescue of fire fighters, but the lift height of current " hook and ladder " for tall-building fire fighting and rescue is limited, and the highest also only have about 65～70 M; And rescue ability is poor, once can only rescue 2～3 people; Simultaneously, " hook and ladder " is bulky, mobility is poor, is subject to the impact of surrounding enviroment etc. of road, traffic, building large, often therefore class impact and missing an opportunity because of a delay.Initiatively the escape mode is exactly that party oneself utilizes certain device, realizes self-escape.Such device is called " high-rise escape apparatus ".For existing escape device for high-rise buildings on market, through market survey, find that the visible lifesaving appliance in current market comprises that pulley adds rope type descending lifeline, roll type descending lifeline, Rope ladder for escaping, escape sliding sleeve, escape umbrella, fire escape etc.But, pulley adds rope type descending lifeline and in use cheese is thrown to ground, rope enters other end from one of descending lifeline and goes out, with a series of pulleys, contact therebetween, under the acting in conjunction of pulley and gear and friction mechanism, frictional resistance is passed to rope, and the other end of rope is connected with the survivor, thus the slow ground that falls.This descending lifeline deep bid rope of need ining succession, size is larger, is difficult at ordinary times be arranged in advance fixed position, and, because two ropes one on the other may be wound around mutually, therefore be only applicable to rescue others under non-fire condition, be difficult to use in and save oneself, and price.Rope ladder for escaping is not suitable for the old man and child uses; The escape sliding sleeve will lean on human body and the fricative resistance of sliding sleeve to reach slow purpose of falling, and easily hurts sb.'s feelings, and the people that body weight is light and child all can not use; Collective's escape device easily more than 100 ten thousand yuan a set of, the ordinarily resident building can't be promoted; Escape umbrella requires floor at least could use more than 220 meters, and the use height of fire escape is below 15 meters, and this has affected their scope of application greatly.In a word, because above-mentioned various escape apparatus all are not easy to use because of its existent defect.Therefore, develop safety-type high-rise escape apparatus a kind of high security, that be convenient to old man and child's use by significant.
For the instrument of high-rise life saving, in disclosed patent, have centrifugal escape apparatus and the fluid damping escape apparatus of individualism, but result of use is not good enough.Unquestionable, escape apparatus is usingd security as peak demand, but all there are potential safety hazard in various degree in existing centrifugal escape apparatus and fluid damping escape apparatus, become the poor main cause of implementation.For example the initial velocity of centrifugal escape apparatus is too high, the human body dropping process is to slow down then at the uniform velocity after first speedup, initial velocity increases too fast being difficult to and controls, increase the feared state of mind to the people, moderating process is too rapid again, cause between human body and fixed mount and produce larger traction force, this traction force adds that the human body self gravitation causes the moment pulling force very large, to such an extent as to be difficult to control, escape is a kind of fear and hasty behavior, the frequent motion state that changes is easily thrown sb. off his guard and causes danger, has increased unsafe factor.This escaping tool all is difficult to effectively control for most people especially Ms, old man and child.In addition, centrifugal escape apparatus must have certain speed just can make centrifugal-block and shell produce friction and reach purpose at the uniform velocity, and in fact there is destabilizing factor in the sliding friction of centrifugal-block, as the frictional behaviour between rubbing surface because sneaking into medium or rainwater flip-flop, the springing phenomenon appears between brake pad and shell, the factors such as brake pad Radial resistant force change, this escape device of security only being placed on to the effective skin friction of centrifugal-block and shell, can not guarantee being perfectly safe of escape personnel, it is on probation that the current test to centrifugal escape apparatus only appears at the new product initial stage, and the escape event belongs to irregular event immediately, by different types of centrifugal escape apparatus sample testing is found, even operation is correct, still having the unsettled phenomenon of decrease speed occurs, thereby can determine that there is certain potential safety hazard in simple centrifugal escape apparatus.Simple liquid condenser also is difficult to effectively implement, its reason is in liquid condenser, to rely on fluid friction to produce resistance, the resistance coefficient of damping fluid is fixed, resistance increasing between impeller and liquid when although decrease speed increases, but the maximum resistance of damping fluid is basic fixing, there will be along with dropping distance increases and the phenomenon of decrease speed increase.Especially now people's living condition improves different with the body-building situation, the partially fat or partially thin gap of health is larger, be difficult to make the damping fluid coefficient that is applicable to a certain colony, even for same people's damper, whether also be difficult to guarantee after long-time use suddenly safety, thereby the liquid condenser scope of application is very narrow, be difficult to guarantee the security of different librarian uses, be unfavorable for promotion and implementation.
Summary of the invention:
The present invention seeks to the problem and shortage for existing centrifugal escape apparatus and the existence of fluid damping escape apparatus, a kind of high-rise escape apparatus that triple dampings superpose one after another that has is provided.
