Description
Technical Field
The invention relates to the field of safety ropes, in particular to an impact-resistant buffering safety rope.
Background
The safety belt for overhead operation is also called a whole-body safety belt or a five-point safety belt, and the material specified by the new national standard GB6095-2009 needs to be processed by terylene and woven belts with higher strength. The whole-body safety belt is a protective article for preventing falling and casualty of high-altitude operation personnel. The safety belt is composed of a belt body, a safety matching rope, a buffering bag and metal accessories, and is generally called as a falling suspension safety belt, and the wearing steps of the high-altitude safety belt are as follows: the wearing braces, the tightening chest straps, the tightening leg straps, the tightening waist belts, the linking belt bodies and the safety ropes play roles in buffering and impact resistance and protect users.
At present, the well-known anti-falling safety rope with the buffering function is formed by a common braided rope/braid and a buffer/bag, wherein the buffer/bag plays a role in buffering falling. Because the buffer/bag and the weaving rope/braid are physically connected, generally in a sewing way, when falling, the buffer/bag and the weaving rope/braid have damage risks, and potential safety hazards are brought. And the buffer/bag is based on the tearing of the woven belt to provide the buffer function, so that in the falling process of the heavy use object, the tearing of the woven belt is difficult to provide high strength and enough buffer, and huge life and property loss is caused in serious cases.
Disclosure of Invention
In view of this, the embodiment of the invention provides an impact-resistant buffering safety rope, which can effectively avoid the damage risk caused by physical connection of the traditional safety rope with a buffering function.
The embodiment of the invention discloses an impact-resistant buffering safety rope which comprises a braided rope and a rope sleeve, wherein the braided rope is braided by a braiding machine, the rope sleeve is woven by the braiding machine, the rope sleeve is wrapped on the periphery of the braided rope, the rope sleeve is of a hollow structure, the braided rope comprises a plurality of stranded ropes, each stranded rope comprises a braided strand and a parallel strand, and the inner diameter of the rope sleeve is larger than the outer diameter of the braided rope.
In one embodiment of the invention, the sum of the number of braided strands and parallel filament strands is 8 strands.
In one embodiment of the invention, the braided strands have an elongation at break greater than the elongation at break of the parallel filament strands.
In one embodiment of the invention, the braided strands are braided from 8 strands.
In one embodiment of the invention, the ratio of braided strands to parallel filament strands is 7: 1, the number of strands of the braided strand is greater than that of the parallel yarn strands.
In an embodiment of the invention, the braided strand and the parallel yarn strand are made of terylene or chinlon.
In an embodiment of the invention, the rope sling is made of anti-cutting core-spun yarn, and the material is polyester and steel wires are wrapped.
In one embodiment of the invention, the outer side of the rope sling is coated with a wear-resistant, flame-retardant and anti-aging coating.
In one embodiment of the invention, the strand number ratio of the braided strands to the parallel filament strands is 6: 2 or 5: 3.
Compared with the prior art, the invention has the following beneficial effects:
1. through the design of a special braided rope, the impact peak value is reduced, the whole body has no sewing physical connection, and a weak ring is not damaged;
2. the rope sleeve with buffering, wear resistance, cutting resistance and flame resistance greatly improves the fall-proof safety coefficient;
3. the falling impact peak value and the safety rope strength can be designed by adjusting the quantity ratio of the braided strands to the parallel strands in a targeted manner, and the safety rope has higher safety and applicability.
