Problems solved by technology
The technical problem existing in the known technology is that this scheme fails to allow multiple people to descend slowly at the same time, but only when one person lands, the second person can operate. For this phenomenon, we have designed a circular multi-person descending device. This method is currently No related patents

Embodiment 1
[0018] Embodiment 1 The circulation type multi-person descending device provided by the present invention includes a mechanical unit and a plurality of one-way rope buckles; the mechanical unit is placed on the top of a plurality of rope one-way buckles; Smooth and fixed in the form of a ring;
[0019] Such as Figure 1-2 As shown, the mechanical unit adopts a symmetrical structure, and the two ends of the hook 2 are respectively placed on the upper ends of the first side plate 1 and the second side plate 14 and fixed; the hook 2 is above the upper spindle 4; the upper spindle 4 and the lower The main shafts 11 are arranged longitudinally, and the two ends of the upper main shaft 4 and the lower main shaft 11 pass through the first side plate 1 and the second side plate 14 respectively, and then install the first friction wheel 3, the second friction wheel 15 and the third friction wheel respectively. Wheel 9 and the fourth friction wheel 22, the two ends of the upper main sh...

The invention provides a cyclical multi-person descent control device which can be used for realizing multi-person escape at the same time by virtue of a mechanical unit and multiple unidirectional rope buckles. Since a rope winding manner is adopted to realize a double-8 shape, ropes and the unidirectional rope buckles can be used cyclically; a rope limiting plate equipped with a U-shaped fork is used for tightening or loosing the ropes to achieve the purpose of auxiliary speed adjustment, thereby further ensuring the safety; and because of the adoption of the unidirectional rope buckles, the ropes only can move downwards relative to the unidirectional rope buckles and can be prevented from automatically sliding upwards. The simultaneous adoption of multiple technical measures ensures that escapers can escape safely at a descent control speed within 1m / s or 2m / s. By using the cyclical multi-person descent control device provided by the invention, multiple escapers can escape from a fire disaster scene more quickly and safely and reach a safe place successfully; and the cyclical multi-person descent control device provided by the invention has the advantages of simple structure, low cost and convenience for use and can be widely used for rescue in fire disasters in high-rise buildings.
Description
technical field [0001] The invention provides a circulation type descending device for multiple persons, which is a descending device capable of rapidly and safely descending multiple persons to the ground at the same time when a fire breaks out on a high floor. Background technique [0002] With the development of society, there are more and more high-rise buildings. However, when unexpected dangers such as fires and gas leaks occur in high-rise buildings, or when an earthquake occurs, how people in the high-rise buildings escape in time and smoothly becomes a technical problem. A Chinese patent with the application number CN02251039.7 discloses a technical scheme called "reciprocating descending device". The program relates to a device used by people on high-rise buildings to escape in an emergency. It includes a hanging wheel for rope winding, a transmission driven by the hanging wheel, a driving wheel that rotates with the transmission, a casing, and a centrifugal bloc...
