Problems solved by technology

[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 weight of 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.

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 present invention relates to an elevator safety device, in particular to an elevator airbag device. Background technique [0002] Currently, elevators that use a winch traction device are used for lifting. During the use of the steel wire rope of the winch traction device, the steel wire not only carries the weight of the elevator, but is also a transmission part of the elevator's lifting power. Therefore, it is easy to cause fatigue or wear of the steel wire rope, which reduces the efficiency of the elevator. Safety performance, if the steel wire rope breaks and the elevator falls, it will cause casualties and property losses. An elevator generator damping safety device has become a safety requirement for elevator use. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an elevator airbag device that utilizes buffer springs, hydraulic cylinders and airbags to absorb...
