Embodiment Construction
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0018] The implementation of the present invention focuses on solving the rebound problem of the cable, and is designed to dissipate energy through the structure when the cable breaks, so that initially only the outer layer of the cable is broken. When a strand breaks, the deformation of the remaining core structure will last longer while still retaining a lot of strength. This relieves the tension on the rope so that the core does not snap immediatel...

The embodiment of the invention discloses a safety early-warning slow-bounce fatigue-resistant cable and a preparation process thereof. The safety early-warning slow-bounce fatigue-resistant cable comprises a cable core, cable strands and a cable jacket, the number of the cable strands is eight or twelve, the cable strands are made of high-strength high-modulus fibers, the cable core is made of high-strength low-modulus fibers, and the cable jacket is made of anti-ultraviolet fibers treated through a post-treatment method. The rope core has the characteristics of high strength and low modulus,the rope strands have the characteristics of high strength and high modulus, and the cable jacket has the characteristic of ultraviolet resistance. The cable has a fracture early warning function, when the impact force borne by the cable exceeds the rated load, fracture is generated, the fracture process occurs twice, when the cable is fractured for the first time, sound emitted by the cable andthe presented visual state warn ship personnel, and after the ship personnel have enough time to transfer to a safe area, the cable is fractured for the second time, that is to say, the cable is completely broken, so that the life safety of the ship personnel can be effectively protected.
Description
technical field [0001] The invention relates to the technical field of cable and its preparation, in particular to a safety warning slow-elastic fatigue-resistant cable and its preparation process. Background technique [0002] With the impact of sea wind and waves on the ship, the corresponding impact energy will gather on the mooring cable of the ship. When the impact force exceeds the load that the cable can bear, the cable will break, and the accumulated energy will be released instantly. The cable pulls back and rebounds, which can easily cause damage to the ship's personnel. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a safety early warning slow elastic fatigue resistant cable and its preparation process, which solves the safety problem of potential injury to ship personnel when the mooring cable breaks suddenly. [0004] The embodiment of the present invention discloses a safety pre-warning slow elastic fatig...
