Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to an eight-strand nylon multifilament cable with a reinforced pipa-shaped buckle. Background Technology

[0002] In ship operations, marine engineering, and heavy lifting, cables must withstand enormous tensile forces, making their overall strength, the reliability of their end connections, and their durability crucial. Existing technologies for traditional cables suffer from the following shortcomings: First, the transition design between the cable body and the end loop is flawed, easily leading to breakage due to stress concentration. Second, the disordered twist distribution among the strands results in poor overall structural stability and insufficient breaking strength, making it difficult to meet the demands of high-intensity operations. Third, the protective sheaths at the free annular ends are mostly single-layer structures, lacking wear resistance and cushioning performance, making them susceptible to damage from friction or impact. Fourth, the lack of effective marking designs hinders rapid identification and maintenance of the cable's condition. Utility Model Content

[0003] To address some of the problems existing in the prior art, this utility model provides an eight-strand nylon multifilament cable with a reinforced pipa buckle. Through optimized structural design, this cable improves strength, stability, durability, and safety performance, and is especially suitable for high-intensity operation scenarios such as ship mooring, lifting and hoisting, and marine engineering.

[0004] To achieve the above objectives, this utility model provides an eight-strand nylon multifilament cable with reinforced pipa-shaped buckles, comprising a cable body, wherein the cable body is woven from seven strands of first nylon multifilament rope and one strand of second nylon multifilament rope in a spiral interlaced arrangement, and the diameter of the cable body is 64mm; both ends of the cable body are integrally formed with pipa-shaped buckles, which are formed into annular free ends by cross-winding; the outer surface of the annular free ends is also covered with a canvas sheath, which adopts a double-layer structure, including a rubber cushioning inner layer and a wear-resistant canvas outer layer arranged sequentially from the inside to the outside.

[0005] In operation, this invention first involves fabricating the cable body, which is woven from seven strands of first nylon multifilament rope and one strand of second nylon multifilament rope in a spiral arrangement, with a diameter of 64mm. Both the first and second nylon multifilament ropes are made of multiple twisted nylon multifilaments with alternating twist directions and opposite twist directions between adjacent strands. The outer surface of the second nylon multifilament rope is coated with a fluorescent warning color, evenly distributed along the axial direction of the cable body. Next, pipa-shaped buckles are integrally formed at both ends of the cable body, and these buckles are cross-wound to form a circular free end, with a length of 1... The cable is 0.8m long, with a 0.3m transition section at the connection point with the main cable. The weaving density of the pipa buckle gradually increases from 8 strands to 12 strands, and the diameter of the transition section gradually changes from 64mm to 96mm at the base of the pipa buckle. Then, the inner rubber buffer layer with anti-slip texture is tightly attached to the outer surface of the ring-shaped free end, and then a 1-2mm thick abrasion-resistant canvas outer layer is wrapped around the outside of the rubber buffer inner layer to form a double-layer canvas sheath. Finally, the edges of the canvas sheath are double-stitched with aramid fiber thread, with a stitch width of 5mm.

[0006] The beneficial effects of this utility model are as follows: The cable body is made of seven strands of first nylon multifilament rope and one strand of second nylon multifilament rope spirally interwoven, with the twist directions between the strands alternating in opposite directions, which significantly improves the stability and load-bearing capacity of the overall structure; the reinforced pipa buckle is integrally formed with the cable body, and its weaving density gradually increases from 8 strands to 12 strands, and the diameter gradually changes from 64mm to 96mm through a 0.3m long transition section, which effectively reduces stress concentration and enhances the reliability of the connection between the end and the body; the canvas sheath adopts a double-layer structure of a rubber cushioning inner layer and a wear-resistant canvas outer layer, and the anti-slip texture on the inner side ensures a tight fit with the ring free end. The wear-resistant performance of the outer layer and the cushioning performance of the inner layer are combined to greatly improve the protection effect of the end and improve durability; the fluorescent warning colors on the second nylon multifilament rope are evenly distributed along the axial direction, which facilitates quick identification of the cable status and maintenance inspection. At the same time, the double-row locking design of the aramid fiber thread enhances the firmness of the sheath edge and prevents it from falling off.

[0007] As a further improvement of this utility model, in order to enhance the structural stability and load-bearing capacity of the cable body, both the first nylon multifilament rope and the second nylon multifilament rope are made of multiple nylon multifilaments twisted together. The twist directions of the first nylon multifilament rope and the second nylon multifilament rope are alternately distributed, and the twist directions of adjacent strands are opposite.

[0008] As a further improvement of this utility model, in order to effectively reduce stress concentration at the end connection and enhance the reliability of the connection, the length of the pipa buckle is 1.8m, and the connection part between the pipa buckle and the cable body is provided with a transition section of 0.3m in length; the braiding density of the pipa buckle gradually increases from 8 strands to 12 strands in the cable body, and the diameter of the transition section gradually changes from 64mm in the cable body to 96mm at the root of the pipa buckle.

[0009] As a further improvement of this utility model, in order to achieve wear resistance and impact resistance and improve the protection effect on the end, the thickness of the wear-resistant canvas outer layer is 1-2mm, and the thickness of the rubber buffer inner layer is 0.5-1mm; the inner side of the rubber buffer inner layer is also provided with anti-slip texture, and the rubber buffer inner layer is tightly attached to the outer surface of the annular free end.

[0010] As a further improvement of this utility model, in order to facilitate the rapid identification and maintenance of the cable status at night or in low light environments, the outer surface of the second nylon multifilament rope is coated with fluorescent warning colors, and the fluorescent warning colors are evenly distributed along the axial direction on the cable body.

[0011] As a further improvement of this utility model, in order to enhance the firmness of the canvas cover edge and prevent the cover from falling off due to friction or stretching during use, the edge of the canvas cover is sewn with aramid fiber thread, and the aramid fiber thread forms a double-row overlock structure on the edge of the canvas cover, with an overlock width of 5mm.
