Description
Technical field
The present invention relates to elevator shock-absorbing technical field, and in particular to a kind of elevator hoistways novel shock absorption device.
Background technology
Damper is arranged in the pit at shaft bottom, to occur causing car to travel over position in contingency
Realize making the purpose of car or weight equalizer safe shutdown during the elevator faults of the orderly closedown position at bottom or top layer.Example
Such as, for the form of damper, a kind of types of springs is described in Japanese Kokai Patent application No.JP2000-136075
Damper and a kind of filling type damper is described in Japanese Kokai Patent application No.JP7-237846.When car is advanced
During orderly closedown position at bottom or top layer, it is configured to be located on pit ground and in face of car or balance weight
Every kind of damper in these conventional shock absorbers of thing can all be contacted with the car or weight equalizer.The downward stroke of damper
Reduce the vibrations being applied on car or weight equalizer.
For car and weight equalizer, car that at least passenger is taken there is provided emergency shutdown equipment so as to
The decline of car is controlled when decrease speed increases for any reason and substantially.Additionally, when the base section of pit is used as making
During people standing space therein, also emergency shutdown equipment can be set for weight equalizer.Emergency shutdown equipment is by car or balance
Weight is fastened on the guide rail guided to the traveling of car or weight equalizer and firmly stops car or weight equalizer.
That is, above-mentioned guide rail serves the work of the supporting arrangement supported to car or weight equalizer when emergency shutdown equipment is activated
It is installed into from pit ground with, the guide rail and is extended vertically upward.
For conventional shock absorber above-mentioned, when car or weight equalizer are impinged upon on damper, greatly
On the part that shock loads partly act on below the damper being arranged in pit ground and make the portion
Divide and produce very big stress.Even if when the emergency shutdown equipment set for car or weight equalizer is activated, being transmitted by guide rail
Shock loads still can partly be acted on the part on the pit ground below guide rail and produce the part
Very big stress (reason is that car or weight equalizer are secured on guide rail and stop suddenly).Therefore, when car or balance
Weight is impinged upon on damper and when emergency shutdown equipment is activated, and pit ground must endure as shaking stress.Result is led
Cause increased the cost for ensuring damper intensity.
In the case where car or weight equalizer are impinged upon on the top of damper, car is decelerated and is stopped, together
When damper carry out downward stroke movement.However, for conventional damper, in addition to length of stroke, for bullet
For spring type damper, it is necessary to increase the total height of damper by its length after compression, or subtract for filling type
For shake device, it is necessary to increase the total height of damper by the total height of oil cylinder.As a result, pit depth must be made correspondingly
It is deeper.
For foregoing discussion, present invention seek to address that one or many in the above mentioned problem of puzzlement conventional elevator damper
Individual problem.

Piston is similar in water tank, it is descending by the extrudable water surface of pressure, the aperture of insertion tank wall is bored on the water tank wall, in tank outer wall
On be coated with aluminium foil, usually these apertures with aluminium foil seal, in sealing state, water will not overflow, when car accidental falling,
Under the enormous impact of car, air bag stress is run downwards, and water is pressurized and breaks through aluminium foil, and water moment from aperture overflows and projects water tank, sedan-chair
Railway carriage or compartment is slowed down, and obtains damping effect.
The air bag is to be filled with compressed air sealing in flexible rubber capsule, using air ground compressibility and the stream of water
Dynamic property realizes elastic reaction, plays auxiliary cushioning effect.
The air bag is partly floated in water body, is connected with water tank bottom by connecting rope, and the air bag is connected with Pressure monitoring and sets
Standby, automatically testing air pressure inside situation can pressurize, it is ensured that air bag has enough support forces at any time when air pressure is inadequate.
The water tank is cylindrical shape, is easy to piston baffle to run up and down.
Water level detector is provided with the water tank, a certain amount of rear Based Intelligent Control moisturizing of water level decreasing is measured, water level is kept.
The aperture is circular port, and aperture is set according to the pressure that water tank bears.
The water tank periphery is provided with captation, is injected in captation when water overflows, and prevents water to be deposited on hoistway
In.
The aperture is arranged on water tank wall in rule or irregular status.
The water tank is integrally formed using mould, is the iron and steel material quality of preservative treatment, and overall endurance is strong, durable, relatively
Cost is relatively low.
The air bag top is provided with piston baffle, and the piston baffle selects foamed aluminium board, is easy to float on the surface, together
When also have stronger support force and elasticity, be unlikely to compressive deformation.The piston baffle is square or cylindrical shape, follows water tank
Shape and design.
The piston baffle selects foamed aluminium board or polyurethane sheet, is easy to float on the surface, and surface and/or bottom surface are set
There is steel plate, prevent from being ruptured in enormous impact force lower piston baffle plate, while also having stronger support force and elasticity, be unlikely to be pressurized
Deformation.
The beneficial effects of the invention are as follows：The present invention changes traditional elevator hoistways damping completely, is subtracted using hydraulic pressure
Shake, while increasing air bag assisted decompression, effect is good, simple structure, long service life, and can recycle, and improves elevator
Security performance.
