Abstract

The invention discloses an airbag shock absorption device for an elevator cage. The airbag shock absorption device comprises a water tank without a cover which is arranged at the bottom of an elevator shaft, wherein the water tank contains water, a floating body is arranged on water surface, an airbag is arranged below the floating body and is used for being compressed, the floating body is similar to a piston in the water tank and can extrude the water surface to descend under pressure stress, a plurality of small holes which run through the tank wall are drilled in the water tank wall, and the external wall of the water tank is wrapped with an aluminum foil. Ordinarily, the small holes are enclosed with the aluminum foil and are in a sealed state, and the water cannot overflow; when the cage accidentally drops, the floating body runs downwards due to stress under the large impact of the cage, the water breaks through the aluminum foil due to pressure and gradually overflows from the water tank from the small holes, the cage is decelerated, and a shock absorption effect is achieved.

Description

technical field [0001] The invention relates to the technical field of elevator damping, in particular to an elevator car airbag damping device. Background technique [0002] Shock absorbers are placed in the pit at the bottom of the hoistway for the purpose of safely stopping the car or the counterweight in the event of an elevator failure causing the car to travel past the normal stop position at the bottom or top floor . For example, in terms of the form of the shock absorber, a spring-type shock absorber is described in Japanese Kokai Patent Application No. JP2000-136075 and an oil-filled shock absorber is described in Japanese Kokai Patent Application No. JP7-237846. type shock absorber. Each of these conventional shock absorbers, positioned on the pit floor and facing the car or counterweight, engage with the Car or counterweight contact. The downward stroke of the shock absorber dampens the shock being applied to the car or counterweight. [0003] As far as the c...
