Life-saving capsule consisting of miniature buffering air bags and other components and arranged in elevator shaft bottom pit

Abstract

A life-saving capsule consisting of miniature buffering air bags and other components and arranged in an elevator shaft bottom pit belongs to the field of elevator safety protection devices, and comprises a clapboard box which is mounted on a lift car projection area, a buffering net and the miniature buffering air bags, wherein the miniature buffering air bags are covered by the buffering net and are arranged in the clapboard box; the life-saving capsule also comprises a separation barrel base which covers the bottom of a lift car buffer, a middle separation barrel, a sponge disc on the top and a sponge cap which is arranged on the sponge disc, or a type II sponge disc which is directly mounted on the top of the life car buffer and a type II sponge cap which is arranged on the sponge disc. The life-saving capsule is mounted in the lift car projection range which is a main area where a person falling in the pit falls in the pit bottom, the miniature buffering air bags are used for exerting the functions of buffering, absorbing energy and gradually increasing resistance, and the life-saving function is realized by soft deformation and collapse; a beneficial remedial measure is realized after the lift car buffer fails under a specific condition; the combination form of the emergency life-saving device is flexible and varied, and the application range is wide.

Description

technical field [0001] The invention relates to an elevator safety protection device, in particular to a rescue cabin which is placed in the bottom pit of an elevator shaft and is composed of miniature buffer airbags and other components.
