an escape device

Abstract

The invention discloses an escape device which at least comprises a safety waist and trouser belt, a prompt drop escape main rope, a prompt drop escape auxiliary rope, a connector, a Kevlar fiber connecting rope, a single speed-limiting box and a damper regulator, wherein the single speed-limiting box is connected onto the prompt drop escape main rope and used for dropping at a constant speed relative to the prompt drop escape main rope, the damper regulator is connected onto the prompt drop escape auxiliary rope and used for controlling the drop speed, one end of the connector is connected onto the safety waist and trouser belt, the other end of the connector is connected onto the prompt drop escape main rope through the single speed-limiting box, one end of the Kevlar fiber connecting rope is connected onto the safety waist and trouser belt, and the other end of the Kevlar fiber connecting rope is connected onto the prompt drop escape auxiliary rope through the damper regulator. Based on improvement of safety protection measures, the drop speed can be automatically regulated according to the weight of an escaper, the ropes are high in strength, fine in abrasion resistance, light in weight and beneficial to carrying and transfer, and the escape device is reasonable in structural design and simple, convenient and rapid to use.

Description

technical field [0001] The invention relates to the field of machinery, in particular to an escape device for safe and rapid escape of trapped persons. Background technique [0002] With the development of social economy, there are more and more high-rise buildings in cities, and the safety crisis of high-rise fires or sudden natural disasters are gradually highlighted. A fire in a high-rise teacher's apartment in Shanghai caused many residents to die in the sea of ​​flames, which sounded the alarm for the fire safety of high-rise buildings in the city. It also made the elevator unusable and the corridors and stairs blocked by smoke in the event of a fire and other emergencies. How to safely and quickly escape the trapped people has become an urgent problem to be solved. [0003] There have been a large number of reports related to building escape equipment in China, and patented technologies related to high-rise building escape equipment have also emerged. In these disclos...

AI Technical Summary

Problems solved by technology

[0004] 1. Existing escape equipment only has movable pulleys or fixed pulleys for single-strand ropes to descend and slide. The escapers cannot control the speed of their descent, which poses a great risk to the escapers and increases the fear of the escapers;

[0005] 2. Although the existing escape equipment is designed with a descending adjustment device, it cannot automatically adjust the deceleration according to the weight of different escapees, and it is easy for a heavy escaper to decelerate too fast and threaten the life of the escapee;

[0006] 3. The existing escape equipment is not designed with an emergency braking device. If the escape equipment fails, the life of the escapee cannot be protected;

[0007] 4. Existing escape equipment is even designed to use electricity as power. When a fire occurs, the power supply is cut off, and the escape equipment cannot be used at all.

[0008] In addition, in these building escape equipment, the ropes used for the rapid descent and the damping materials used to control the descent are mostly traditional steel materials, which are heavy and are not conducive to wearing and transferring.
