Embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.
Embodiment one:Reference Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of buffer structure for elevator safety, including arranged on elevator
Buffer cell 2, clump weight 5, drag rope 4 and the directive wheel 3 arranged on the upside of buffer cell 2 of 1 bottom of well, the buffering
Unit 2 include air bag 21, the partition plate 23 arranged on the top of the air bag 21, the venthole 24 on the partition plate 23, around setting
Elastic support 25 and the sealing cover 22 on the elastic support 25, the sealing cover 22 in the upside of venthole 24 is logical
Cross the elastic support 25 with the partition plate 23 to be connected, the drag rope 4 is set around on the directive wheel 3, the counterweight
Block 5 is connected by the drag rope 4 with the partition plate 23.
By setting clump weight, drag rope and directive wheel, after lift car, which rises, not to be in contact with partition plate, clump weight
Because self gravitation descends through drag rope and directive wheel pulling partition plate rising movement, because partition plate rises so as to stretch air bag at this time
Sealing cover is statically placed on the upside of venthole by resilient support block support, enters air bag by venthole immediately positioned at air bag extraneous air
It is interior so that air bag automatic inflating, air is discharged by venthole in air bag when lift car normally declines, partition plate is subject to elevator car
The downward pressure in railway carriage or compartment and decline partition plate at this time naturally and pull clump weight to rise by drag rope and directive wheel, with this in positive reason
Clump weight and partition plate, which are mutually drawn, under condition moves up and down.
By setting around the elastic support on the upside of the venthole so that elastic when sealing cover is not influenced by external force
Support column support sealing cover is statically placed on the upside of the venthole, and inside air bag is connected by venthole with outside air, when close
Capping is subject to sealing cover during the external impacts that lift car produces to block venthole and cause inside air bag air excessive, when close
Lift car external force suffered by capping influences sealing cover after releasing and is recovered by elastomeric support column support to original position.
With reference to Fig. 2 and Fig. 3, a kind of above-mentioned buffer structure for elevator safety, the sealing cover 22 and the venthole
24 are mutually matched and compress, the sealing cover 22 be subject to during longitudinal pressure the sealing cover 22 to be covered on the venthole 24 so that
The venthole 24 is closed.By setting venthole, the sealing cover on elastic support, sealing cover is subject to lift car to fall
When impact force Squeezing sealing lid by venthole block closing so that air bag in air can not be excessive so that air bag keep inflation
State and then the buffering that plays the role of to lift car prevent lift car hard landing, and then protection staff safety.
Further included with reference to Fig. 1 and Fig. 4, a kind of above-mentioned buffer structure for elevator safety, the buffer cell 2 arranged on institute
State several 7 air valves of decompression on 21 side wall of air bag.By the decompression air valve on bladder sidewall, under lift car is unexpected
Air, which is extruded from the decompression air valve on bladder sidewall, when pendant impacts the air bag under inflated condition, in air bag slowly discharges so that
Air bag because being caused balloon rupture by lift car impact force extruding gasbag, does not on the one hand stablize decompression protection air bag and improves air bag
Security, on the other hand absorbs the effect that impact force when part lift car falls further functions as buffering lift car.
With reference to Fig. 1 and Fig. 4, above-mentioned a kind of buffer structure for elevator safety, covered with one on 21 side wall of air bag
The cellular elastic material 6 of layer.By covering one layer of cellular elastic material on bladder sidewall, auxiliary balloon is from air bag
Side wall absorbs impact force caused by the lift car of part, so as to improve the buffer capacity of air bag.
Referring to Figures 1 and 2, above-mentioned a kind of buffer structure for elevator safety, the clump weight 5 pass through the traction rope
Rope 4 draws the partition plate 23 and drives the air bag 21 along upper and lower to stretching, extension and compress.
With reference to Fig. 1 and Fig. 3, a kind of above-mentioned buffer structure for elevator safety, the partition plate 23 is preferably hard material.
With reference to Fig. 1 and Fig. 3, a kind of above-mentioned buffer structure for elevator safety, the sealing cover 22 is preferably hard material
Material.
Embodiment two:With reference to Fig. 5 and Fig. 6, the present embodiment two and the difference of embodiment one are:On the sealing cover
Layer 221 is preferably hard material, and the sealing cover lower floor 222 is preferably elastic material, and other structures are similar to embodiment one,
This is just no longer repeated.Lift car is uniformly born to sealing cover using hard material sealing cover upper strata by sealing cover upper strata
Caused pressure, sealing effect of the sealing cover lower floor using elastic material lift-off seal lid to venthole.
The implementation process of the utility model:
Step 1:With reference to Fig. 1 and Fig. 3, under normal condition, lift car 11 rises, and clump weight 5 is because under self gravitation effect
It is in extended state that drop pulls partition plate 23 to rise mobile air bag 21 by drag rope 4 and directive wheel 3, and sealing cover 22 is not by outer
Power influences elastomeric support column 25 and supports sealing cover 22 to be statically placed in the upside of the venthole 24, inside air bag 21 by venthole 24 with
Outside air is connected, and is now placed in 21 extraneous air of air bag and enters the interior air bag 21 of air bag 21 certainly by venthole 24 immediately
Dynamic inflation.
Step 2:With reference to Fig. 1, Fig. 2 and Fig. 3, under normal condition, lift car 11 declines, and 11 bottom of lift car is to close
The compressive resilience support column 25 that capping 22 and partition plate 23 apply under normal circumstances keeps keeping gas to the holding state of sealing cover 22
21 inner air of capsule is communicated with the outside, and the air in air bag 21 is discharged by venthole 24, so that air bag 21 is in contraction
State, partition plate 23 are subject to the downward pressure of lift car 11 and decline partition plate 23 at this time naturally and pass through 4 rope of traction rope and directive wheel 5
Clump weight 5 is pulled to rise.
Step 3:With reference to Fig. 1, Fig. 3 and Fig. 6, under 11 fall condition of lift car, sealing cover 22 is subject to lift car 11 to fall
Venthole 24 is blocked closing so that the air in air bag 21 can not be excessive, in air bag 21 by the impact force Squeezing sealing lid 22 when falling
Air is extruded from the decompression air valve 7 on 21 side wall of air bag and slowly discharges.
The above is only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto,
All non-essential modifications to the present invention made by this concept, should all belong to the row for invading scope of protection of the utility model
For.
