Description
Technical field
The present invention relates to elevator shock-absorbing technical fields, and in particular to a kind of lift car air sac damping device.
Background technique
Damper is arranged in the pit at shaft bottom, in contingency to occur that carriage is caused to travel over position
The purpose for making carriage or weight equalizer safe shutdown is realized when 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 carriage is advanced
When orderly closedown position at bottom or top layer, it is configured to be located on pit ground and in face of carriage or balance weight
Every kind of damper in these conventional shock absorbers of object can all be contacted with the carriage or weight equalizer.The downward stroke of damper
Reduce the vibration being applied on carriage or weight equalizer.
For carriage and weight equalizer, at least the carriage taken of passenger be provided with emergency shutdown equipment so as to
The decline of carriage is controlled when decrease speed obviously increases for any reason.In addition, the bottom part when pit is used as making
When people standing space therein, also emergency shutdown equipment can be set for weight equalizer.Emergency shutdown equipment is by carriage or balance
Weight is fastened on the guide rail guided to the traveling of carriage or weight equalizer and firmly stops carriage or weight equalizer.
That is, above-mentioned guide rail plays the work of the supporting arrangement supported when emergency shutdown equipment is activated to carriage or weight equalizer
With the guide rail, which is installed into from pit ground, to be extended vertically upward.
For conventional shock absorber above-mentioned, when carriage or weight equalizer impinge upon on damper, greatly
On the part that shock loads locally act below the damper being arranged in pit ground and make the portion
Divide and generates very big stress.Even if when the emergency shutdown equipment for carriage or weight equalizer setting is activated, by guide rail transmission
On the part on the pit ground that shock loads still can locally act below guide rail and generate the part
Very big stress (reason is that carriage or weight equalizer are secured on guide rail and stop suddenly).Therefore, when carriage or balance
Weight impinges upon on damper and when emergency shutdown equipment is activated, and pit ground must endure as vibration stress.As a result it leads
It causes to increase the cost for ensuring damper intensity.
In the case where carriage or weight equalizer impinge upon on the top of damper, carriage is decelerated and is stopped, together
When damper carry out downward stroke movement.However, for conventional damper, other than length of stroke, for bullet
For spring type damper, it is necessary to increase the total height of damper by compressed length, or filling type is subtracted
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 aforementioned discussion, present invention seek to address that one or more in the above problem of puzzlement conventional elevator damper
A problem.
Summary of the invention
A kind of design of structure is simple, and using effect is good technical problem to be solved by the present invention lies in providing, at low cost, can
The lift car air sac damping device of recycling.
The technical problems to be solved by the invention are realized using following technical scheme:
A kind of lift car air sac damping device, the uncovered water tank including being set to elevator shaft bottom, in the water tank
Equipped with water, it is provided with a floating body on the water surface, is provided with air bag below the floating body, for compression, floating body class in water tank
Like piston, by extrudable water surface downlink is depressed, the aperture of numerous perforation tank wall is bored on the water tank wall, on tank outer wall
It is coated with aluminium foil, usually these apertures are sealed with aluminium foil, are in sealing state, water does not overflow, when carriage accidental falling, in sedan-chair
Under the enormous impact in compartment, floating body stress is run down, and forms cushion effect to carriage, and when impact force is excessive, aluminium foil is broken through in water compression,
Water moment from aperture, which overflows, projects water tank, and carriage is slowed down, and damping effect is obtained.
The air bag is to be filled with compressed air sealing in flexible rubber capsule, using air the stream of compressibility and water
Dynamic property realizes elastic reaction, plays auxiliary cushioning effect.
The air bag partly floats in water body, is connect by connecting rope with water tank bottom, which 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 run up and down convenient for floating body.
The floating body selects foamed aluminium board or polyurethane sheet, and convenient for floating on the surface, surface and/or bottom surface are provided with steel
Plate prevents the floating body under enormous impact force from rupturing, while also having stronger support force and elasticity, is unlikely to compressive deformation.
Water level detector is provided in the water tank, after water loss, automatic water supplement is pasted with aluminium foil, can at any time more after
It changes.
The floating body is cylindrical shape, follows the shape of water tank and designs.
The aperture is round hole, and aperture is set according to the pressure that water tank is born.
The water tank periphery is provided with captation, enters in captation when water overflows to penetrate, water is prevented to be deposited on hoistway
In.
The aperture is arranged on water tank wall in rule or irregular status.
The water tank uses anti corrosion high strength metal material, can be iron and steel material quality, and whole endurance is strong, durable, relative at
This is relatively low.
The beneficial effects of the present invention are: the present invention changes traditional elevator shaft damping completely, subtracted using hydraulic pressure
Shake, while increasing air bag assisted decompression, effect is good, and structure is simple, long service life, and can be recycled, and improves elevator
Security performance.
