High-rise building emergency evacuation rescue control speed slow descent device and method

Abstract

The invention discloses a high-rise building emergency evacuation rescue control speed slow descent device and method. The device comprises an automatic slow descent device fixed to a building and a rope reel matched with the automatic slow descent device through a winding safety rope; an auxiliary safety rope is fixedly arranged at the position, beside the automatic slow descent device, of the building, and a manual slow descent device is arranged on the winding safety rope and the auxiliary safety rope in a sliding manner. The method comprises the steps of firstly, high-rise building emergency evacuation preparation; secondly, manual slow descent device mounting; thirdly, rope reel starting; fourthly, control speed slow descent of escape personnel; fifthly, landing unbundling of the escape personnel; sixthly, resetting of the rope reel. The descent speed of the escape personnel can be automatically adjusted, manual deceleration brake is achieved, the device can be repeatedly used, operation is easy, safety and reliability are achieved, and complex and long-term training is avoided.

Description

technical field [0001] The invention belongs to the technical field of high-rise building escape and rescue, and in particular relates to a high-rise building emergency escape and rescue speed control and slow-down device and method. Background technique [0002] With the continuous improvement of urbanization, the number of high-rise buildings continues to increase, and the vibration or fire of high-rise buildings has become a very serious safety hazard that threatens the safety of people's lives. Due to the complexity and diversification of the building structure, once a high-rise building is in danger, it will be very difficult to rescue, and the blockage of elevators and emergency exits will inevitably bring great difficulties to the rescue work. The descending device provides convenience for self-rescue in dangerous situations, but the existing descending devices still have the following problems. First, most descending devices can only descend but not ascend, and canno...

Due to the complexity and diversification of the building structure, once a high-rise building is in danger, it is very difficult to rescue, and the blockage of elevators and emergency exits will inevitably bring great difficulties to the rescue work

The descending device provides convenience for self-rescue in dangerous situations, but the existing descending devices still have the following problems. First, most descending devices can only descend but not ascend, and cannot be reused during self-rescue. Rescue costs and fast installation bring troubles; second, most descenders cannot control the speed, and escape quickly descends according to their own weight. Uncontrolled descending may instead cause people to enter the dangerous area of ​​the lower layer of the building, causing accidents. Expansion; the 3rd, the existing descending device has relatively high requirement to the escape skill, needs to carry out certain training, when the trapped person in distress descends from a height, if the descending device is not used properly, when an emergency occurs due to the emotional and psychological conditions of the personnel It will lead to many unsafe factors in self-rescue, such as the inability to operate the descent device correctly due to tension, which will make it difficult to carry out rescue work, and it is difficult to play a real safety role
