Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a highly flexible and high tensile strength marine cable. Background Technology

[0002] In the shipping industry, cables play a vital role, for example, in operations such as mooring ships at docks and connecting and towing with other ships.

[0003] Existing marine mooring lines have many shortcomings. On the one hand, some mooring lines have poor flexibility, and many have limited tensile strength. When faced with large tensile forces, such as when a ship encounters strong winds and waves, the mooring lines may break, leading to serious consequences such as loss of ship control. At the same time, during long-term use, they are easily affected by seawater corrosion and wear, resulting in a shortened service life and reduced safety. Therefore, we have proposed a highly flexible and high-tensile-strength marine mooring line to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly flexible and tensile-strength marine cable.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A highly flexible and tensile-strength marine cable includes a cable body comprising an inner core, a rope intermediate layer, and an outer sheath, with the rope intermediate layer located between the inner core and the outer sheath. The rope intermediate layer comprises polyester fiber rope, polyurethane rope, nylon rope, carbon fiber rope, and hemp fiber rope. The polyester fiber rope, polyurethane rope, nylon rope, carbon fiber rope, and hemp fiber rope are wound around the outer side of the inner core. A steel wire is inserted into the nylon rope, and multiple strands of steel wire are spirally wound within the hemp fiber rope.

[0007] Preferably, the outer side of the polyester fiber rope, polyurethane rope, nylon rope, carbon fiber rope, and hemp fiber rope is coated with a waterproof coating.

[0008] Preferably, the inner core is made of multiple strands of polyaramid fibers woven in an eight-strand braiding method.

[0009] Preferably, the outer protective layer includes a rubber layer and a sheath, wherein the rubber layer is sleeved on the outside of the rope's middle layer, and the outer side of the rubber layer is sleeved with a sheath.

[0010] Preferably, the outer side of the sheath is coated with a corrosion-resistant coating, and the outer side of the corrosion-resistant coating is coated with a wear-resistant layer.

[0011] Preferably, both sides of the cable body are fixedly fitted with fixing sleeves.

[0012] Preferably, the rubber layer is wrapped with a glass fiber mesh.

[0013] The beneficial effects of this utility model are:

[0014] 1. The rope's tensile strength is greatly improved by using a combination of high-performance fiber ropes and steel wires in the middle layer design, enabling it to withstand greater tension during ship operations and ensuring operational safety.

[0015] 2. The combination of various materials and the reasonable structural layout allow the cable to maintain good flexibility, making it easy to operate and use, and less prone to breakage.

[0016] 3. The waterproof coating on the outside of each rope, the corrosion-resistant coating on the outside of the sheath, and the wear-resistant layer, etc., enable the rope to effectively resist the effects of harsh marine environmental factors such as seawater corrosion and abrasion, extend its service life, and reduce the cost of use.

[0017] 4. The special weaving method of the inner core and the detailed design such as the glass fiber mesh wrapped inside the rubber layer further enhance the overall structural stability and strength of the cable, and comprehensively improve the performance of the cable.

[0025] Reference Figure 1-4 A highly flexible and tensile-strength marine cable includes a cable body 1, with fixing sleeves 6 fixedly fitted on both sides of the cable body 1. The cable body 1 includes an inner core 2, a rope intermediate layer, and an outer sheath 5, with the rope intermediate layer located between the inner core 2 and the outer sheath 5. The rope intermediate layer includes polyester fiber rope 301, polyurethane rope 302, nylon rope 303, carbon fiber rope 304, and hemp fiber rope 305. Polyester fiber rope 301 is wound around the outside of the inner core 2, polyurethane rope 302 is wound around the outside of the inner core 2, nylon rope 303 is wound around the outside of the inner core 2, carbon fiber rope 304 is wound around the outside of the inner core 2, and hemp fiber rope 305 is wound around the outside of the inner core 2. A steel wire 4 is inserted inside the nylon rope 303, and multiple strands of steel wire 402 are spirally wound inside the hemp fiber rope 305.

[0026] In this embodiment, the outer surfaces of polyester fiber rope 301, polyurethane rope 302, nylon rope 303, carbon fiber rope 304, and hemp fiber rope 305 are all coated with a waterproof coating 306. The waterproof coating 306 on the outer surfaces of polyester fiber rope 301, polyurethane rope 302, nylon rope 303, carbon fiber rope 304, and hemp fiber rope 305 can prevent seawater and other liquids from penetrating into the rope, thus avoiding the impact of moisture on performance and service life.

[0027] In this embodiment, the inner core 2 is made of multiple strands of polyaramid fibers in an eight-strand braiding method. Polyaramid fibers themselves have excellent properties such as high strength and high modulus. The eight-strand braiding further ensures the stability and tensile strength of the inner core 2, providing strong core support for the entire cable.

[0028] In this embodiment, the outer sheath 5 includes a rubber layer 501 and a sheath 502. The rubber layer 501 is sleeved on the outside of the middle layer of the rope, and the sheath 502 is sleeved on the outside of the rubber layer 501. The outer side of the sheath 502 is coated with a corrosion-resistant coating 503, and the outer side of the corrosion-resistant coating 503 is coated with a wear-resistant layer 504. The rubber layer 501 is wrapped with a fiberglass mesh, and the outer side of the sheath 502 is coated with a corrosion-resistant coating 503. The outer side of the corrosion-resistant coating 503 is coated with a wear-resistant layer 504, which can resist the corrosion of seawater and the wear caused by contact with other objects during use, significantly extending the service life of the cable.

[0029] In this invention, the inner core 2 is composed of multiple strands of polyaramid fiber using an eight-strand braiding method. Polyaramid fiber itself possesses excellent properties such as high strength and high modulus. The eight-strand braiding further ensures the stability and tensile strength of the inner core 2, providing strong core support for the entire cable. A steel wire 4 is interwoven within the nylon rope 303, and multiple strands of steel wire 402 are spirally wound within the hemp fiber rope 305. Through the combination of various fiber ropes with different properties, combined with steel wire reinforcement, the tensile strength of the cable is effectively improved. Simultaneously, the combination of multiple materials also facilitates… To maintain good flexibility, the outer sheath 5 includes a rubber layer 501 and a sheath 502. The rubber layer 501 is fitted on the outside of the middle layer of the rope, and the sheath 502 is fitted on the outside of the rubber layer 501. The rubber layer 501 can play a role in buffering, shock absorption and certain protection, while the sheath 502 further strengthens the protection of the internal structure. The outer side of the sheath 502 is coated with a corrosion-resistant coating 503, and the outer side of the corrosion-resistant coating 503 is coated with a wear-resistant layer 504, which can resist the corrosion of seawater and the wear caused by contact with other objects during use, significantly extending the service life of the cable.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
