Embodiment Construction

[0015] The materials required for the manufacture of the invention are steel and high wear-resistant and high-strength composite materials, and the material properties can meet the foldability and mechanical requirements of the airbag. The guide body structure for storing airbags is designed according to the specific conditions of the elevator airbags in terms of its structure and shape, and the manufacturing methods are mechanical manufacturing methods such as integral molding or welding and assembling. Its actual elevator anti-fall safety airbag device size is designed according to different shapes and sizes of different elevators, but the way of execution is still the same. After the required parts are manufactured, they will go to the site for installation and debugging.

Abstract

The invention discloses an anti-falling safety air bag device for an elevator. The anti-falling safety air bag device is manufactured according to the aerodynamics principle. A body of the anti-falling safety air bag device for the elevator is composed of an air bag (1), a guide body (2) storing the air bag, a connecting end body (3) connected with an elevator car, and a gas inlet and outlet valve (4). The air bag (1) is connected with the guide body (2) storing the air bag. The air bag is neatly coiled and stored in the guide body (1) storing the air bag under the power effect of a motor, and meanwhile the gravity generated by the air bag (1) and the elevator is borne. The air inlet and outlet valve (4) adjusts the size of an air inlet and outlet hole according to the gravity condition during elevator running, and valve adjustment can be conducted on an air valve according to preset parameters in the falling situation till the speed is stably reduced to zero by the elevator and the elevator stops at a safe position.

Description

[0001] 1. Technical field [0002] The invention belongs to the field of aerodynamic applications [0003] 2. Technical background [0004] At present, the method of elevator safety has not been changed. The usual elevator safety is controlled by sensors, but it is still extremely unsafe, because sensors and simple clamps and other devices cannot control the elevator fall, especially the aging of the elevator. The problem is also the Achilles' heel of the elevator. This product uses the airbag tracking technology, so that the airbag is always tightly connected to the bottom surface of the elevator car, which can completely control the elevator's descending speed and ascending speed, and can avoid any possibility of the elevator falling; [0005] 3. Contents of the invention [0006] 1. Purpose of the invention: the present invention will solve the problem of elevator falling, and the existing safety and anti-falling devices for elevators still cannot guarantee that the elevat...
