Description

Riding escape car of the many people of high building fire self-rescue and lifesaving method thereof

Technical field

The present invention relates to lifesaving appliance and lifesaving method technical field, particularly relate to lifesaving method and device that the many people of a kind of high building fire self-rescue escape together.

Background technology

World today's high building stands in great numbers, and has been the epoch of city jungleization.But when certain one deck of high building happens suddenly serious fire, what if stay in numerous resident families of twenty or thirty layer, the people that help the old and guide the young? how to escape? in order to answer this difficult problem, recent decades, many researchers researched and developed with great concentration, had made very big effort, but solution still not yet in effect so far.

We know that the lifesaving appliance of fire in high buildings really is the help equipment that " A thousand days the country natures its soldiers and fall for one day's battle " " only permitted success, mustn't be failed " concerning user (survivor).Can't permit a point defect for this unit or method.The simplicity of installing when the lifesaving appliance of fire and method must possess security, reliability, use, when operation easily, controllability and temporal rapid property.Described security, the security performance that finger device itself has, and user's psychologically sense of security when using.Described reliability, the reliability of the security performance of finger device on space-time all remains unchanged as device its function in various climatic environments, and its every function also should be as excellent as before when and for example taking out use after device is shelved 3-5.

We analyze the relevant patent of part that China Intellectual Property Office that this paper takes passages has announced, look in this technical field before and the level that reached of present fire in high buildings lifesaving appliance and method.

1, Chinese utility model patent number is ZL87201163 " a high-altitude safe drop device " by name.Technical scheme is: safe cheese, descending lifeline, auxiliary catch, safety belt constitute, and technical characterictic is that the friction plate friction eceleration descends; China utility model patent ZL97219428.2 " high building fire-extinguishing and lifesaving device " by name application in 97 years, openly announce technical scheme in January, 99: rope, fixed pulley, control wheel, the hand brake, support is characterized in that the brake pads friction eceleration descends.All there are two problems in these two Patent equipments, A, when the survivor uses, and device preparation program is too much and complicated, as want proping, safety rope is medium through device, be not the professional again the ordinary people among extremely terrified can't correctly use, can't escape in case make mistakes.Discuss together in B, below " 4 ".

2, Chinese utility model patent prospectus publication number CN86207480, open day in September, 87, " steel band lifesaving appliance " by name.Technical scheme: steel band, drum, centrifugal brake, be characterized as the brake pad friction eceleration and descend, the survivor is that steel band is reduced to ground.Its maximum shortcoming of this patent lifesaving appliance, also be fatal shortcoming be when the survivor be that steel band drops to ground from the high building window, a rule steel band is stayed on the wall face, only stands in upstairs original position and just steel band can be regained.Suppose that high building is 30 layers, on the window of same upright position, there is family more than 20 to use this device lifesaving, the 1st people has got off, when can the 2nd people to the 20 people getting off, this elder generation left rule steel band of person down isolates each and every one the human body of long blade with the survivor of back without mercy as one, and you are invaded under the situation of pausing, can't hiding at uncontrollable device.So this device is injured others and ruined oneself, be can't implement, have no safe and reliable speech.

3, Chinese utility model patent, the patent No. are ZL00260959.2, in October, 2000 applying date, September calendar year 2001 Granted publication day, " high building fire-proof self-help life-saving device " by name.The technical scheme feature: the steel wire rope reel, be full of the seal case of liquid, piston, connecting rod, bent axle are done between damped motion system, housing and the bent axle to force piston to do damped motion with establishing damping hole on sealing ring sealing, the piston.This a kind of really good new equipment, qualification rate during its product export can accomplish 100%, not only safe but also reliable, operate also convenient and strength-saving, but problem goes out on the sealing ring in this Patent technology characteristic (numbering 16), the fire lifesaving appliance does not use everyday, if shelving sealing in 3 years, 5 years for a long time, to iris out the probability of seepage fault high, to cause in the closed box that liquid is inadequate to be caused piston not have do damped motion the steel wire rope reel is slowed down, thereby cause whole failure of apparatus, the survivor will can't escape from life, so the security reliability of this device is poor.

4, in August, 2003 Chinese invention patent specification publication number CN1579578A number of patent application 03138884.1 applying date, in February, 2005 day for announcing, " a kind of building lifesaving method and device thereof " by name.Technical scheme: exterior wall is fixing puts the fixed pulley that rope sheave, lever and lever one distal process go out exterior wall, feature: lever one end is established the brake pad contact and is put the rope sheave periphery, and the brake pad friction is put rope sheave and slowed down and descend.There are two problems in this patent, first, the deceleration of using brake pad (sheet) to realize putting rope sheave, the decrease speed that makes it to reach a safety can live personnel and arrives ground, problem is that this device is not a round-the-clock device, when weather is good, it is no problem using this device, in case can sleet sky generation disaster, then clip a large amount of rainwater in the overhead high wind of high building, ice and snow, access to plant, the then friction of brake pad (sheet) and wheel periphery is because of rainwater, the intrusion of ice and snow makes the coefficient of friction cataclysm, thereby causes skidding of brake pad (sheet), cause whole device to lose efficacy at once, the survivor can't escape from life.This problem all exists in 1,2 two described lifesaving appliance of segment of this section.So adopting the lifesaving appliance of friction plate (piece) braking of open-type is not round-the-clock equipment, security reliability is not high.Second, in this patent lifesaving method and the device characteristic " distal process of lever goes out exterior wall and establishes a fixed pulley ", suppose that tab length is more than reaching about 20-30 centimetre, imagine, serious fire is in the 8th buildings in the 30th floor height buildings, on same vertical window, each layer window represented a user, and this device all is installed, on the exterior wall on this window side, many give prominence to iron on wall face, be inserted on your the only way which must be passed bayonet is horizontal just as one, you glide along wall from the window of 30 floor heights is other, and the speed of downslide is uncontrollable again also uncontrollable, slide in this situation, you are with black and blue all over.Therefore there are significant deficiency in this building lifesaving method and device, are unsafe, also can't promotion and implementation.

5, up to now, it is investigated read all through the bulletin, disclosed life-saving device for high-rise fire hazard, all can only provide is alone escape, imagines: 30 floor heights, one tame 4 people of a resident family upstairs, husband, wife, son and one's old mother parent, in the very first time of fire, hung up properly lifesaving appliance, 4 philtrums can only have 1 people to escape from, who escapes? whoever can not leave relatives behind and escape alone, can do not decline any more, the most valuable like this escape time has just been delayed.

In sum, how according to the actual conditions on the high building, make one family of high building resident family that is in the fire both safe and reliable together, the device and method of self-help escape that can be quick, controlled has again become the research staff's of this technical field R﹠D direction and target.
