High building life saving of the present invention, is exclusively used in skyscraper and recovers, when high-rise building with fire disaster, earthquake
During etc. the condition of a disaster, distress personnel can be implemented to save oneself, mutually rescue without foreign aid using the present apparatus, ground of safely landing in time,
It possesses advantages below：
1st, using being simply easily manipulated, few is required to user；Only have two steps to operate using the present apparatus：Linking and jump (are jumped
Outside exit window), it is sagging, cantilever the stretching linked up with use, the deploying of in place, the shelves post that hastens forward of next limiter of speed, specified negative
The control of lotus is all automatically performed, and is most simple and direct in like product；
The present apparatus is fixedly mounted on the floor of window or balcony and under ceiling, when occurring dangerous situation, first
Survivor is connected with starting limiter of speed, jumped out, and the locking device (referring to bolt machine) of starting limiter of speed is automatically turned on, telescopic boom
Outside (referred to as cantilever) auto-extending to wall, survivor is set not scratched with the exterior wall of building, first survivor and starting
Limiter of speed is together slowly fallen, while the steel wire rope (cable wire) in starting limiter of speed is drawn out, until first survivor's landing,
Now steel wire rope has hung down to ground.When starting limiter of speed departs from telescopic boom, the supervention limiter of speed adjacent with it is automatic
The front end for moving on to telescopic boom is standby, and second survivor can be connected with supervention limiter of speed after about 5 seconds, jump out, along same
Root steel wire rope is slowly fallen.Hereafter a people was evacuated every 5 seconds.
2nd, it is rational in infrastructure, it is easy to use；The design principle of the present apparatus is：It more complicated would rather must also exchange for and use
It is convenient, survivor (such as under flame baking) when disaster occurs without seeing specification temporarily；During whole escape, escape
Survivor is not required to see specification, and linking need to be only completed according to the schematic representations on telescopic boom, two actions are jumped out, remaining
A series of actions be automatically performed by the present apparatus, without human intervention.
3rd, security is good, with higher safety coefficient, speed stability, brake validity；The present apparatus is the current country
It is only multiple survivors is utilized the life-saving apparatus form high building with steel cable continuous lifesaving, in being current similar product
Evacuation speed highest (720 people/hour), operation are most easily.
4th, non-maintaining, service life is long, using measures such as corrosion resistant material, solid lubrication, even if should ensure that idle tens of
Year, still can normally it use.
High building life saving of the present invention, rational in infrastructure, being that the current country is only takes multiple limiter of speeds to exist
With being installed in series on steel cable, can continuous lifesaving escape apparatus；Occupation of land is small, using 3 millimeters of naked steel wire rope, stores for future use
When, in the case of limit for height identical, volume shared by the rigging of the present apparatus is only the 1/27 of current commercial descending lifeline；Using simple easy
In manipulation, few is required to user, the distress personnel of floor below can be sued and laboured by the brake of survivor's autonomous control midway；Safety
Property is good, and its evacuation speed is highest in current similar product；Non-maintaining, service life is long.
Skyscraper is directed in the market, the main product for fire-extinguishing and lifesaving sold is descending lifeline, the present invention
Described high building life saving, there is following advantage by comparison：
1st, descending lifeline can not brake halfway, so can only save oneself, it is impossible to realize mutually rescuing to other floors.The present apparatus due to
Limiter of speed lands with survivor, therefore can be braked by survivor's autonomous control midway, and navigability is strong, can be to floor below
Distress personnel is sued and laboured.It also is available for fire fighter to carry with, any selection hanging point is used to rescue.
2nd, descending lifeline is limited because of its structure, be a rigging head and the tail exchange, it is reciprocal use, so previous people's landing must be treated
Afterwards, the latter talent can be used.The present apparatus is natively limited due to the difference of structural principle without this, after previous people falls, without
Land, need to only be spaced about 5 seconds, latter people can jump out Deng him, that is to say, that allow 2 to 5 people synchronous on same steel cable
Fall.If there are 6 people in the room that is in danger, only need all to escape danger within 1 minute.Only this item can make the present apparatus in scene of fire
Or compareed in fire drill with like product and show advantage.
From the point of view of current published data, the present apparatus, which is that the current country is only, takes multiple limiter of speeds in same steel
Be installed in series in cord, can continuous lifesaving escape apparatus, its evacuation speed is highest in current similar product.Do an image
Metaphor, existing all kinds of descending lifelines are all rifles, can only single-shot, and the present apparatus is then machine gun, can be with running fire.This feature causes
The present apparatus is not only applicable to fire escape, is also applied for the rope drop operation of helicopter.
3rd, the steel wire rope of descending lifeline is slightly very much a disadvantage.The steel wire rope for the descending lifeline that current each factory is produced is without exception all
Wrap up textile cover to increase coefficient of friction, make rigging external diameter up to 9 millimeters.And the present apparatus is due to directly using 3 millimeters
Naked steel wire rope, will have more advantages in this respect.When storing for future use, in the case of limit for height identical, body shared by the rigging of the present apparatus
Product is only the 1/27 of current commercial descending lifeline.
4th, the rigging length of descending lifeline is necessary " custom-made by size ", and such as design height just can only be 10 for 10 layers of descending lifeline
Layer is used, and taking 9 layers or 11 layers can not all use, or can only be used for one person-time；The present apparatus is limited without this, is broadly divided into by limit for height
Several gears, such as 5 layer one gear or 10 layer of one gear.
5th, a preferable design should make decrease speed is less to be influenceed by payload, and descending lifeline is applying maximum negative
When lotus and minimum load, its decrease speed differs as many as 9.3 times unexpectedly, in contrast to this, only poor 2 times of the present apparatus.
6th, descending lifeline must drag the next rigging freely dangled for being up to tens of meters, it is possible to be stuck in or be entangled in wall
Hidden danger is formed on protrusion.The present apparatus is different because of structure, without this hidden danger.
7th, the present apparatus does not have too high requirement to material and machining accuracy, therefore cost is relatively low.Each limiter of speed cost about 200
~300 yuan, complete sets of products cost (exemplified by containing 5 limiter of speeds) about over thousands of member.

The gravity vertical of user pulls open one section of rational distance below suspension gear 15 with the arrival end of the steel wire rope of supervention limiter of speed 4.
But if the number run on the steel wire rope of lower section reaches rated load M, then between the first cylinder 2004 on helical and shelves post
Frictional force can be very big, the machine user's is underweight to overcome this frictional force, and helical clamp would not be acted.Once total
Load is less than M, and helical clamp can just discharge a grade post.The parameter of helical is made by rated load M, the gradient of inner sleeve front end, one
The standard weight of user is determined with coefficient of friction.
The setting of trigger mechanism is based on following consideration：

Mechanism automatic unlocking is sent out, the people that original is waited is to depart from cantilever to automatically fall off along steel wire rope.
(3) in addition to starting limiter of speed, the stage casing of user hereafter all in steel wire rope, i.e. have steel wire above him
Rope, lower section also has, if there is the user not yet landed below, steel wire rope now bears very hightension, very firmly.For
Prevent steel wire rope from being rubbed with user's body, the gravity vertical of steel wire rope and user need to be made to pull open a certain distance, it is not small
