Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the first embodiment, as shown in fig. 1 to 3, the rope comprises a rope body 1, the end of the rope body 1 is bent to form a rope buckle 2, the end of the rope body 1 is connected with the end face of the rope body 1 through a three-strand thin rope 3 in a winding manner, a protective sleeve 4 is sleeved on the three-strand thin rope 3, a polyurea coating 5 is sprayed on the protective sleeve 4, a strand 6 comprises a polyurethane fiber inner core 7, high-strength strands 8 are wound on the outer portion of the polyurethane fiber inner core 7 at equal intervals, a polyester coating sleeve 9 is sleeved on the outer portion of the high-strength strand 8, the high-strength strands 8 are twelve strands, the high-strength strands 8 are wound on the outer side of the polyurethane fiber inner core 7 in an annular array manner, the polyester coating sleeve 9 is woven by a polyester material, the diameter can be 24, 32 or 48 strands, the high-strength strands 8 are composed of an ultra-high-molecular-weight polyethylene rope yarn 10 and a polyamide rope yarn 11, the number ratio of the ultra-high-molecular-weight polyethylene rope yarn 10 to the polyamide rope yarn 11 is 11:1, the diameter of the three strands of string 3 is 3 mm to 6 mm.

Example two, on the basis of example one, the rope body 1 is braided from twelve strands 6.

The working principle is as follows: during work, under a high-load environment, if a large instant tensile force is generated, due to the arrangement of the polyurethane fiber inner core 7, the high-strength strand 8 and the polyester coating sleeve 9, a stepped energy reduction mode is generated to protect the rope body 1, when strands of the ultra-high molecular weight polyethylene rope 10 in the rope body 1 are broken, the polyamide rope 11 strands of the strands in the rope body 1 respond first, the rebound energy generated due to instant breakage is unloaded, when the polyamide rope 11 strands are not enough to counteract the rebound energy, the polyester coating sleeve 9 at the periphery responds again, under a normal condition, the broken rope body 1 is basically directionally controlled within a certain safety range, the polyurethane fiber inner core 7 at the inner part completely controls the movement path direction of the rope body 1, and the safety risk is reduced to zero;

after the rope body 1 bears the force, certain heat can be generated, the ultra-high molecular weight polyethylene rope yarns 10 can effectively exert the wear resistance and the high temperature resistance of polyamide fibers at the moment, the instant fracture of the rope body 1 is maintained, the rebound energy of the rope body 1 is reduced, the swing amplitude after the rope body 1 is fractured is controlled, the range of the operation track is reduced, the rope body 1 is controlled in the polyester coating sleeve 9 under the action of the polyester coating sleeve 9, the rope body 1 is retracted to move, the polyurethane fiber inner core 7 at the center fully exerts the high elastic energy of the rope body, the stroke of the rope body 1 is reduced, after the rope body 1 is instantaneously extended and released, the rope body 1 is retracted again to stabilize the state, and the purpose of preventing rebound is achieved.
