Description
Technical field
The present invention relates to elevator shock-absorbing technical field, and in particular to a kind of lift car water body damping 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.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of structure design simply, and using effect is good, and low cost can
The lift car water body damping device of recycling.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of lift car water body damping device, including the uncovered water tank of elevator hoistways bottom is arranged at, in the water tank
Equipped with water, a floating body piston is provided with the water surface, the floating body piston is similar to piston in water tank, by the extrudable water surface of pressure
It is descending, the aperture of several insertion tank walls is bored on the water tank wall, aluminium foil is coated with tank outer wall, usually these apertures
Sealed with aluminium foil, in sealing state, water will not overflow, when lift car accidental falling, under the enormous impact of car, floating body
Piston stress is run downwards, and water is pressurized and breaks through aluminium foil, and water moment from aperture is overflow and projects water tank, and car is slowed down, subtracted
Shake effect.
The water tank is cylindrical shape, is easy to floating body piston to run up and down.
The floating body piston 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 the floating body piston under enormous impact force from rupturing, while also having stronger support force and elasticity, be unlikely to be pressurized
Deformation.
Water level detector is provided with the water tank, after water loss, automatic water supplement is pasted with aluminium foil, can at any time more after
Change.
The floating body piston is cylindrical shape, follows the shape of water tank and designs.
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 non-corrosive metal (NCM) material, and overall endurance is strong, durable, relative cost
It is relatively low.
The beneficial effects of the invention are as follows：The present invention changes traditional elevator hoistways damping completely, is subtracted using hydraulic pressure
Shake, effect is good, simple structure, long service life, and can recycle, and improves the security performance of elevator.
