Vertical conveying channel and uses thereof

摘要

A vertical conveying channel is made of elastic fabric. The elastic fabric's latitude elastic deformation rate is 100˜450%, latitude resilience is 300˜2500N, and latitude elastic recovery rate is 70˜100%; preferably, the latitude elastic deformation rate is 120˜400%, the latitude resilience is 350˜2300N, and the latitude elastic recovery rate is 75˜98%; more preferably, the latitude elastic deformation rate is 140˜350%, the latitude resilience is 550˜2200N, and the latitude elastic recovery rate is 80˜96%; most preferably, the latitude elastic deformation rate is 170˜300%, the latitude resilience is 750˜2000N, and the latitude elastic recovery rate is 85˜94%. The vertical conveying channel can be used for vertical conveying of cargo or personnel, preferably used in the field of lifesaving, engineering or military.

1. A vertical conveying channel, comprising:
an inner surface and outer surface, an inner space that longitudinally extends with at least one end opened, the inner surface of the channel is elastic, and an inner diameter of the channel is less than a diameter of an object to be transported along the channel, and the object to be transported along the channel is pressed by contracting of the inner surface of the channel during use, to slow down a falling speed of the object; wherein, the inner surface of the channel is made of elastic fabric, the elastic fabric has a latitudinal elastic deformation rate of 100% to 450%, a latitudinal resilience of 300N to 2500N on condition of latitudinal elongation at break of 80%, a latitudinal elastic recovery rate of 70% to 100%, a latitudinal breaking strength of 800N to 4000N, and a latitudinal plastic deformation rate of 5% to 25%; and the elastic fabric has a longitudinal elongation at break of 2% to 45%, the elastic fabric has a longitudinal breaking strength of 1500N to 5000N, wherein, the elastic fabric is weaved as a latitudinal twofold structure textured in the latitudinal direction, based on 3/1 cross-twill, or is weaved with twill weave, plain weave, or is knitted as a two-side weft-knitted structure with rib-knit.
