Abstract

The invention discloses a fall protection car. The fall protection car comprises an outer car body and an inner car body; the inner car body is hung inside the outer car body through safety blocks; alimiting block is arranged between the top of the inner car body and the outer car body; a buffering air bag device is connected to the bottom of the inner car body through a mounting frame and comprises a nylon fiber air bag, an inflation device and an impact sensor, wherein the nylon fiber air bag is arranged in a folded mode, the inflation device is connected to the nylon fiber air bag, and theimpact sensor is electrically connected to the inflation device; air buffering devices are further arranged on the lower side of the inner car body and are fixed to the bottom surface of the outer car body; and vent holes are formed in the top and the bottom of the outer car body separately. The fall protection car has the advantages of being remarkable in buffering capacity and capable of reducing injuries to personnel.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to a fall protection car. Background technique [0002] The elevator is mainly divided into machine room, shaft and pit, car and landing part. The machine room can control the car to stop between floors to achieve the effect of transporting people and goods. Today's elevators are generally equipped with speed limiters, safety gears, emergency stop devices and other devices to prevent the car from falling, but news of major safety accidents caused by elevators falling occasionally occurs, mainly due to falling accidents caused by overweight Mainly buffer by the buffer of the pit part in the existing technology, when the car falls, the effect is limited, and the personnel inside the car is very prone to fractures or more serious accidents. Contents of the invention [0003] In order to overcome the defects of the prior art, the purpose of the present invention is to p...
