Elastic tightening type aerial work rope net

Abstract

This utility model relates to the field of high-altitude operation technology, specifically an elastic tightening high-altitude operation rope net, comprising a crisscrossing rope body, the intersections of which are heat-fused and pressed together to form a solid knot, and a double-layered sewn closed-loop rope channel at the edge, with an outer pull rope passing through the channel and its length greater than the channel circumference, the two ends being connected by a metal connecting ring to force the edge of the rope to expand and tighten autonomously, and a binding rope spirally wrapped around the outer circumference of the outer pull rope to form an intermittent loop, which is anchored to the outer frame by an adjustable knot, forming a four-level transmission chain of rope net - outer pull rope - binding rope - frame. The rope body is made of polyester or nylon single fiber material, and the outer pull rope and binding rope are independently selected and combined with elastic fibers or mixed with them, achieving self-tensioning without external force through the length difference of the outer pull rope; the binding rope nesting design allows for independent disassembly and replacement of the outer pull rope; the edge closed loop and heat-fused nodes simultaneously improve tear resistance, providing passive fall protection for high-altitude operations in construction and power.
