Falling self-rescuing device for elevator

Abstract

The invention discloses a falling self-rescuing device for an elevator, relates to the field of self-rescuing devices, and aims at solving the problems that a passenger without a buffer measure in a car directly impacts the ground to cause hazards of fracture and the like when the elevator falls at a high speed. The falling self-rescuing device for the elevator comprises two upper fixed pipes (1), two lower fixed pipes (2), two rebound springs (3), two damping springs (4), two damping links, two handrail links (6), two seat links (7) and multiple seat ropes (8), wherein the two upper fixed pipes (1) and the two lower fixed pipes (2) are fixedly arranged in the car in a parallel manner; the two rebound springs (3) are arranged in the upper fixed pipes (1); the two damping springs (4) are arranged in the lower fixed pipes (2); the two damping links (5) are inserted into cavities of the upper fixed pipes and the lower fixed pipes; the two handrail links (6) are mounted at the upper parts of the damping links; the two seat links (7) are mounted at the lower parts of the damping links. When the elevator falls at the high speed, the passenger can pull open the seat links (7); the multiple seat ropes are opened to form a soft seat; the passenger is seated on the soft seat, and clasps the handrail links; the buffering is increased by means of the combined action of the rebound springs (3) and the damping springs (4) after the passenger falls to the ground; the hard landing is avoided; the casualty, which is generated due to fracture, of the passenger is avoided furthest.

Description

technical field [0001] The invention relates to the field of self-rescue devices, in particular to an elevator falling self-rescue device. Background technique [0002] With the acceleration of urbanization in China, the supply of land in cities and towns is becoming increasingly tense, so high-rise buildings also appear in large numbers, among which office buildings, commercial and residential mixed buildings, residential quarters or office buildings are basically equipped with elevators; elevator failures also occur from time to time , There are two main types of elevator failures: one is that the elevator suddenly stops running; the other is that the elevator loses control and falls rapidly. How to protect yourself in the car once you encounter an elevator failure has become a compulsory course: 1. How to call for help when the elevator door fails: The current method is that if the elevator stops suddenly, first of all, don’t panic. You can try to keep pressing the door b...

AI Technical Summary

Problems solved by technology

[0003] Although there are multiple anti-falling measures in the elevator, when all the methods fail and the elevator falls, the passengers in the car will be in a state of weightlessness, and will continue to accelerate, and finally hit the bottom with the car at a very high speed, which will easily cause passengers to be paralyzed. fracture, causing injury

There is no better way to avoid this phenomenon at present, and reports of domestic elevator falling injury accidents also occur from time to time.
