Problems solved by technology

However, this kind of external support force for controlling the falling speed must be relatively large, which is very difficult for people with less strength, especially the elderly and children.
And the tight hoop in the cloth bag has only a small elastic space because of the hose, so it is difficult for fat people to pass through the cloth bag smoothly.
Therefore, the scope of application of this drop bag is very small

Abstract

The invention relates to a vertical transfer passage. The passage is made of elastic fabrics of which the latitudinal elastic deformation rate is 100-450 percent, the latitudinal restoring force is 300-2500N, and the latitudinal elastic recovery rate is 70-100 percent; preferably, the latitudinal elastic deformation rate is 120-400 percent, the latitudinal restoring force is 350-2300N, and the latitudinal elastic recovery rate is 75-98 percent; more preferably, the latitudinal elastic deformation rate is 140-350 percent, the latitudinal restoring force is 550-2200N, and the latitudinal elastic recovery rate is 80-96 percent; and most preferably, the latitudinal elastic deformation rate is 170-300 percent, the latitudinal restoring force is 750-2000N, and the latitudinal elastic recovery rate is 85-94 percent. The vertical transfer passage can be used for vertically transferring goods or persons and preferably used in the fields of lifesaving, engineering or military matters.

Description

technical field [0001] The invention relates to high-altitude lifesaving, engineering, military and other fields. Specifically, it relates to a vertical conveying channel and its application. Background technique [0002] At present, in some special emergency occasions, such as life-saving, engineering, military and other fields, helicopters are often required to carry out vertical transportation of distressed or military personnel, and the way that is often adopted is to use lifelines or parachutes. [0003] Disclosed as Chinese patent CN03138884.1 is a kind of fire rescue method and channel thereof that use rope to drop people from building. It is fixed on the outer wall of the building and presets a rescue passage including a rope release wheel and a lever coiled with a safety rope. When in distress, the escape personnel pull out the safety hook at the free end of the safety rope from the rescue passage, fix it on the life belt on the body, and then fall along the outer...
