Descent device and method of using the same

Abstract

The invention provides a descent control device and a use method of the descent control device. The descent control device comprises a rotatable rope wheel (110) and a first fixing piece (140) used for fixing the rope wheel (110) on a building structure. A life line is wound on the periphery of the rope wheel (110). A containing groove (112) is formed in the middle of the rope wheel (110). A damping device (130) used for limiting the rotating speed of the rope wheel (110) is arranged in the containing groove (112). The descent control device is cheap and easy to use. By means of the damping device, under the conditions that no manual control or external force (such as electric power) assistance exists, an escaping person can land safely, controllably and fast.

Description

technical field [0001] The invention relates to a high-rise escape device, in particular to a descending device used for high-rise escape. Background technique [0002] With the development of the urbanization process, there are more and more high-rise buildings. The use of high-rise buildings not only improves the utilization rate of urban land and shows the style of the city, but also brings some safety hazards. For example, when disasters such as fires and earthquakes break out, people who are in high-rise buildings are generally difficult to escape. [0003] At present, high-rise buildings are rarely equipped with escape tools. When a disaster occurs, people on the upper floors of the building can only escape through safe passages or waiting for rescue. Under the circumstances, the life safety of the trapped personnel will be greatly threatened. In view of the above problems, people have developed escape tools such as descending devices, but the existing descending dev...

Problems solved by technology

[0003] At present, high-rise buildings are rarely equipped with escape tools. When a disaster occurs, people on the upper floors of the building can only escape through safe passages or waiting for rescue. Under the circumstances, the life safety of the trapped personnel will be greatly threatened. In view of the above problems, people have developed escape tools such as descending devices, but the existing descending devices have the following disadvantages: ① The damping in the initial state is the smallest , descending at the maximum speed, resulting in the escape personnel can only slow down the descent speed by increasing the damping method, such as improper operation or failure of the descending device, it is easy to cause safety hazards such as too fast descending speed; ②Most descending devices require manual control However, the escape personnel generally operate for the first time when escaping, and they are prone to panic when escaping, and they are easy to fail to escape due to operational errors; ③The structure is complex, the manufacturing cost is high, it is difficult to be popularized and applied, and it has not been generally accepted by the public
