Description
Technical field
The present invention relates to a kind of overhead escape device.
Background technology
Along with the arrival of modernized society, increasing high building will be built, and the potential safety hazard of high building is also more and more.This also allows people from fire in high buildings, and the difficulty of escaping in blast strengthens.And the people who dies because of fire is every year ten hundreds of.And at present domestic and international escape apparatus mainly contains following several:
1. Elevator.At high building, set up box escape elevator outward, when fire occurs, take lift escape, but this mode needs powerful motor, if there is the situation that electric power is unable to supply, it,, by ineffective, if had a power failure halfway, also can bring very large danger so;
2. iron ladder Emergency Ladder.A bogie side frame outside high building is reinstated the emergency ladder that iron is done, and when fire occurs, people can flee from this place, and fireman also can, from the fire fighting of getting on, rescue people here.If but this mode runs into and has flare to scurry out, block iron ladder access road, that will be very large threat, also has this speed slow, also can bring obstruction, and the utmost point is unfavorable for the shank the wounded or the elderly, children's escape;
3. rope ladder escape, when fire occurs, by ready rope ladder, from roof, or oneself balcony is emitted from this place and is escaped from the sea of fire;
4. cable type escape device, is also current most species, and most widely used escape mode can be divided into following a few class according to the difference of mode of braking:
(1) liquid flow damp type.Liquid flow damp type is the potential energy that utilizes liquid flow damping that people is fallen, and is converted into the heat energy of liquid.Its main feature is: liquid-damped size depends on the size of outer load, thus no matter external force have muchly, can decline with more constant speed, but very huge the uses inconvenience of the mechanism of this device;
(2) cornerite adds manual mode.Such device is to manage to increase the cornerite between steel wire rope and wheel, and the frictional force between rope and wheel is increased, and utilizes in addition one, controlled device machine to control the speed declining.Although these class methods are simple in structure, be subject to the impact of coefficient of friction larger.If cornerite is too large, likely block; Cornerite is too little, and control is had any problem and is not easy to operate;
(3) batch impact type.It is to consume by impact the gravitional force that people declines.It requires the pressure angle of driving link and driven member as far as possible large, but can not self-locking.
Due to the deficiency of above escape device, more convenient, more practical high-rise escape apparatus is more and more important when fire disaster escaping.
Summary of the invention
In order to solve above-mentioned technical problem, the object of this invention is to provide a kind of escape device for high-rise buildings, what this device adopted is frictional damping, by centrifugal principle speed governing, makes the personnel can be to downslide in fair speed, and the ground of arriving safe and sound.The present invention is full mechanical system, safe and reliable, simple in structure, and maintainability is good.
In order to realize above-mentioned object, the present invention has adopted following technical scheme:

As further improvement, described ratio wheel is eccentric cam, and the below, right side of ratio wheel is provided with gag lever post.
As further improvement, described deboost axle comprises axis body and cylindrical shell, and barrel jacket is located on axis body, and cylindrical shell is quality of rubber materials.
As further improvement, the first described spring has coefficient of elasticity, and described coefficient of elasticity makes runner when rotating speed 3.0 ~ 3.5m/s, and slider has the pulling force that enough centrifugal force overcomes the first spring.
As further improvement, described blind hole has 6, and 6 blind holes are distributed on runner, is provided with described the first spring and slider in 6 blind holes.
As further improvement, the described clamping arm of force is connected and composed by bent plate, and the upper and lower end of bent plate becomes 140 ~ 150 °, and described last item arranges the corner part of bent plate.
Escape device for high-rise buildings of the present invention, employing be frictional damping, by centrifugal principle speed governing, make the personnel can be to downslide in fair speed, and the ground of arriving safe and sound.So just can give first aid in time the personnel of scene of fire.The advantage of its relative other escape apparatus is:
1. simple in structure, operation is very easy, child, and old man is even the wounded, and disabled person also can be own or under other people help a little, device be installed;
2. safe and reliable, in the process declining, speed will be well controlled, can not be too fast, can not be too slow, and reasonably gliding mutually under speed, can within the limited time, be rescued like this;
3. adopt machinery control fast, not electricity consumption, need regularly to safeguard, and cost is high because electric, and the preservation that mechanical type can be stable for a long time, performance is stablizing than electricity also;
4. be applicable to various crowds, that we mainly consider is old man, child, the wounded, or overwrought crowd that cannot own control rate in dropping process.So want equipment cruise control, can in the situation that not needing any operation, personal security be delivered to ground.
