Abstract

The invention discloses an elevator safety airbag device. The elevator safety airbag device consists of a hydraulic cylinder, a buffer plate, a buffer spring, a crash sensor, a controller, a gas emitter and an airbag. Hydraulic oil is filled in the hydraulic cylinder, dropping impact force of an elevator is absorbed by utilizing the hydraulic oil, and the impact force is converted into pressure energy of the hydraulic oil; partial drop impact force of the elevator is reduced by utilizing the buffer spring; and moreover, the airbag is exploded to inflate and cushion the elevator, the dropping impact force of the elevator is reduced, and casualties or financial losses are prevented or reduced.

Description

technical field [0001] The invention relates to an elevator safety device, in particular to an elevator safety airbag device. Background technique [0002] At present, the hoist traction device is used to lift the elevator. During the use of the steel wire rope of the hoist traction device, the steel wire rope not only bears the weight of the elevator, but also is the transmission part of the elevator's lifting power, so it is easy to cause fatigue or wear of the steel wire rope, which reduces the elevator. Safety performance, in case the steel wire rope breaks, the elevator will fall and cause casualties and property losses. An elevator generator damping safety device has become a safety requirement for elevators. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an elevator safety airbag device, which uses buffer springs, hydraulic cylinders and airbags to absorb the impact force of the el...
