Description

High-rise life saving mechanism

Technical field

The utility model relates to a kind of escape mechanism, particularly a kind of high-rise life saving mechanism.

Background technology

Modern society's high building is grown thickly, and has brought many facilities and out and out benefit to us.This is the sign of social progress, in case but high building breaking out of fire, resident in the high building but may be because can not in time find passway for escaping, or passway for escaping hinders by big fire and can not realize quick escape, and therefore people face great danger, and fire in high buildings also becomes high building resident's bad dream, it has brought very big hidden danger for people's personal safety, and this also is the insoluble always difficult problem of people.As everyone knows, Shanghai City Shanghai Business School dormitory building breaking out of fire recently, 4 schoolgirls commit suicide by jumping out of the building, four adolescence maidens go away from us like this, very much regrettable, we can't help expecting in distressed, if in those high building rooms escape device reliably has been installed, such tragedy just can not take place once more yet.Yet currently marketed fire in high buildings escape device kind rareness, some apparatus structure complexity, and price is higher, and some reliability is not high, and also some has many limitation, and all combination property is not high mostly.And high-rise life saving mechanism is rarely found in the existing market, and is used for military in a large number or mountain-climbing.And the common drawback of a small amount of civilian descending lifeline is exactly: cost an arm and a leg, and the operation technique complexity, cost performance is low, can not extensively be popularized etc.

The visible lifesaving appliance in market comprises that pulley adds rope type descending lifeline, roll type descending lifeline, Rope ladder for escaping, escape sliding sleeve etc. at present.But, pulley adds rope type descending lifeline and in use cheese is thrown to ground, rope enters the other end from one of descending lifeline and goes out, contact with a series of pulleys 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 links to each other with the survivor, thus the slow ground that falls.This descending lifeline deep bid rope of need ining succession, size is bigger, is difficult to be installed in advance the fixed position at ordinary times, and since one on the other two ropes may twine mutually, so only be applicable under the non-fire condition and rescue others, is difficult to use in and saves oneself, and price is expensive.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 hurts sb.'s feelings easily, and people that body weight is light and child all can not use; Collective's escape device is more than 100 ten thousand yuan of one cover easily, and the ordinarily resident building can't be promoted.

The utility model content

The purpose of this utility model is to provide a kind of simple in structure, easy to use, cost is lower, safe and reliable a kind of high-rise life saving mechanism.

In order to achieve the above object, the technical scheme that the utility model is taked is: a kind of high-rise life saving mechanism, comprise main shaft, described main shaft is installed on the casing, one side of described main shaft is equipped with rope sheave, opposite side is equipped with lever supporting disk, centrifugal bar, being connected with to flexibly connect point on the described lever supporting disk is the lever of fulcrum, the long-armed end of described lever is arranged on centrifugal top on the described centrifugal bar, the end of galianconism is arranged on the top of slow dish, and the arc briquetting that is complementary with described slow dish is installed on the end of described lever short arm.

The utility model is based on lever principle in sum, when fire comes interim, the survivor lies in the free-ended waistband of escaping rope on the waist, jump out from window, gravity drives main shaft and rotates the axle moment that rotates, the lever supporting disk, centrifugal bar, lever and main shaft rotate with same angular speed, meanwhile, a centrifugal end that produces centrifugal action at lever, and by lever power is amplified, on slow dish, produce a bigger normal pressure, be proportional to the physical principle of pressure based on frictional force, the arc briquetting compresses slow dish and produces a bigger frictional force, and frictional force is opposite with the gravitational moment direction to the square of main shaft, and the people is slowly descended with a less acceleration, when reaching a certain safety speed, moment of friction and weight torque balance, this descendant at the uniform velocity descends, the ground of arriving safe and sound.

The specific embodiment

Specify a kind of more excellent embodiment of the utility model below in conjunction with accompanying drawing.

Referring to Fig. 1, a kind of high-rise life saving mechanism, comprise main shaft 3, described main shaft 3 is installed on the casing 8 by bearing, one side of described main shaft 3 is equipped with first pin, 4 rope sheaves 5 that are fixed on the main shaft 3, opposite side is equipped with second pin, 12 lever supporting disk 10 and the centrifugal bars 14 that are fixed on the main shaft 3, be connected with on the described lever supporting disk 10 with the pin joint point is the lever 11 of fulcrum, described lever 11 long-armed ends are arranged on centrifugal 15 top on the described centrifugal bar 14, the end of galianconism is arranged on the top of slow dish 7, the arc briquetting 9 that is complementary with described slow dish 7 is installed on the end of described lever 11 galianconism, on the described slow dish 7 friction plate is installed.

Embodiment: as shown in Figure 2, the utility model can be integrated on the curtain, at the pelmet place of curtain 18 the utility model high-rise life saving mechanism 19 is installed; Because curtain generally all is mounted on the window, when fire takes place the escape personnel can utilize on the escaping rope 20 fixture will oneself be fixed on the escaping rope, jump off by delaying earthward from window then and fall the purpose that reaches escape, high-rise life saving mechanism 19 convenience are installed like this, do not take other spaces.

When fire takes place, the user spurs escaping rope 20 and falls, and rope sheave 5 is owing to rolled up the rotation of escaping rope drive beginning the thereon in advance, and user's dropping process is owing to be subjected to the continuous action of gravity, so falling speed will continue to increase, the rotating speed that therefore makes rope sheave 5 drive main shaft 3 increases; Because main shaft 3 and 5 of rope sheaves are fixed by pin, so rope sheave 5 rotating speeds and main shaft 3 rotating speeds are consistent, in like manner: main shaft 3 also will drive lever supporting disk 10 and centrifugal bar 14 rotates with identical rotation direction and the identical speed of revolving; Be positioned at this moment on the centrifugal bar 14 centrifugal 15 will owing to centrifugal action along centrifugal bar 14 centrifugal moving, and therefore contact with lever 11 right-hand members; When user's decrease speed increased, the speed of mainshaft was fast more, and suffered centrifugal force is big more, gave the pressure of lever 11 right-hand members also just big more; Based on lever 11 amplification principles, the pressure that acts on lever 11 right-hand members will be exaggerated and be carried in lever 11 left ends, and lever 11 left ends are turned to the inside around fulcrum, contact with friction plate on the slow dish 7; When main shaft 3 rotating speeds speed, the centrifugal force that acts on centrifugal 15 will increase, because the amplification of lever 11, the power that acts on lever 11 left ends will increase simultaneously, make that the pressure on the friction plate increases; Be proportional to the physical principle of pressure based on frictional force; Frictional force on the friction plate will increase greatly, and this frictional force acts on the lever 11, make lever 11 slow down around the velocity of rotation of main shaft 3; Slowing down of lever 11 rotating speeds because the interlock effect of pin also makes the rotating speed of main shaft 3 slow down, thus make the synchronization of rope sheave 5 reduce, finally make user's falling speed slow down.And when user's decrease speed slowed to a smaller value, centrifugal 15 because the decline of rotating speed caused weakening of centrifugal force synchronously, made centrifugal 15 to weaken to released state with lever 11 effects, and centrifugal 15 pairs of levers, 11 right-hand member active forces reduce; Based on lever principle, lever 11 left ends will reduce synchronously for the pressure of friction plate; Pressure is more little, and frictional force is more little; Lever 11 will increase around the axle rotating speed, thereby make main shaft 3 rotating speeds increase, and finally make user's decrease speed rise gradually.

Final effect, reduction of speed is too fast under the user, and mechanism will make its speed reduce; And cross when slow when reduction of speed under the user, mechanism will make its decrease speed increase, thus make the user with one stable and safe speed land, thereby guaranteed personnel's escape safety.
