Problems solved by technology

[0002] In a high-rise building, if the vertically ascending elevator suddenly falls due to failure, the effective buffering distance of the buffer spring usually placed at the bottom of the elevator shaft is only tens of centimeters, so the hard fall of the elevator car falling from a high altitude cannot be avoided.
The door of the elevator in use suddenly opens abnormally, and passengers may habitually step in. At this time, there is no buffer protection device at the bottom of the elevator shaft or on the top of the elevator itself, and passengers will inevitably be severely disabled or fall to death

Embodiment Construction

[0014] like figure 1 As shown, the multi-stage cushioning air cushion includes more than two individual mylar air cushions which are combined with each other. Each single polyester film inflatable air cushion is an approximately cube-shaped air bag made of polyester film as the outer wall. figure 1 The single polyester film inflatable air cushions are stacked up and down, and the two adjacent air cushions are fixed to each other. Among them, the wall of the single air cushion 1 on the top layer is the thinnest, and the wall of the single air cushion 2 on the bottom layer is the thickest. The thickness of the wall increases sequentially from top to bottom. 3 among the figure is filling and deflation nozzle, can adopt the structure similar to tire air valve.

[0015] like figure 2 As shown, each air cushion of this multi-stage cushion air cushion is filled with air, and then placed at the bottom of the elevator shaft. When an accident occurs and the elevator car body 4 fall...

Abstract

A multi-stage buffer air cushion is disclosed, and comprises more than two single polyester film air filling cushions which are combined together. The single polyester film air filling cushions can be stacked together up and down and also can be sheathed together one by one. The multi-level buffer air cushion is filled with air and arranged at a bottom of an elevator shaft. When an accident occurs and an elevator falls on the air cushion, partial air cushions burst after being stressed, so that the buffering deceleration time of the elevator is prolonged, and the buffer deceleration distance is increased, the impact force is alleviated, and the casualty accidents are reduced.

Description

technical field [0001] The invention relates to a buffer device for receiving falling objects, a multi-stage buffer air cushion. Background technique [0002] In a high-rise building, if a vertically ascending elevator suddenly falls due to failure, the effective buffering distance of the buffer spring usually placed at the bottom of the elevator shaft is only tens of centimeters, so the hard fall of the falling elevator car cannot be avoided. The door of the elevator in use suddenly opens abnormally, and passengers may habitually step in. At this time, there is no buffer protection device at the bottom of the elevator shaft or on the top of the elevator itself, and passengers will inevitably be severely disabled or fall to death. Contents of the invention [0003] The present invention aims to propose a new buffer device to replace the buffer spring at the bottom of the elevator shaft, which can obtain longer buffer distance and buffer time, reduce casualties, and is a mu...
