Abstract
Description
Technical Field
[0001] This utility model relates to the field of rope and cable manufacturing technology, and in particular to a high-strength tensile composite cable. Background Technology
[0002] In today's industrial and engineering fields, cables serve as crucial connection and load-bearing components, and their performance directly impacts the safety and efficiency of various operations. Traditional cables, however, are increasingly revealing numerous drawbacks when faced with complex working conditions.
[0003] In terms of tensile strength, existing cables lack sufficient tensile capacity. In marine engineering, the deep-sea operating environment places extremely high demands on the tensile strength of cables. For example, mooring cables for offshore oil platforms must withstand the platform's own weight, wave impact, and the tension generated by sea winds. Ordinary cables are highly susceptible to tensile deformation or even breakage under prolonged exposure to such high-intensity tension, severely impacting operational safety and continuity. In the construction industry, the hoisting of large building materials, such as the steel structure hoisting of high-rise buildings, also places extremely stringent requirements on the tensile strength of cables. Existing cables, due to their inadequate tensile strength, cannot stably bear heavy loads, hindering construction progress and posing significant safety hazards.
[0004] From a durability perspective, existing cables have a relatively short service life under the influence of various environmental factors. Their aging resistance is poor; long-term exposure to the outdoors, including ultraviolet radiation, oxygen, and moisture, easily leads to aging and degradation of the cable material, reducing its strength. In high-temperature environments, such as cables near industrial furnaces, the material properties deteriorate due to the high temperature, increasing the risk of cable deformation and breakage. In low-temperature environments, such as polar expeditions and outdoor operations in cold regions, the cable material becomes brittle, its toughness decreases, and it cannot withstand normal tensile and impact forces. Furthermore, if the cable comes into contact with oil, chemicals, or other contaminants, it is easily corroded, leading to structural damage and a significantly shortened service life.
[0005] Furthermore, the structural design of traditional cables also has flaws. Their internal structure is loose, lacking density and stability. Under stress, the internal components cannot work efficiently and collaboratively, resulting in a significant reduction in overall tensile strength. When subjected to impact or vibration, the internal structure is prone to displacement and damage, further weakening the cable's performance.
[0006] In summary, existing cables have many shortcomings in terms of tensile strength, durability, and structural stability, making it difficult to meet the needs of modern engineering and industrial development. There is an urgent need to develop a new type of high-strength tensile composite cable to solve these problems.
[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0010] The cable core includes a tensile core wire, rope one, rope two, rope three, rope four, rope five, rope six, and a bundle layer. Rope one, rope two, rope three, rope four, rope five, and rope six are arranged in a twisted manner around the tensile core wire as the center, and the bundle layer is located on the outside of rope one, rope two, rope three, rope four, rope five, and rope six.
[0011] A second filling layer is provided in the gaps between multiple cable cores, and a first filling layer is provided in the gaps between multiple cable cores and the protective layer.
[0012] The twisting direction of multiple cable cores is opposite to the twisting direction of ropes 1, 2, 3, 4, 5 and 6 on the tensile core wire.
[0013] Preferably, the tensile core wire is made of multiple bundles of steel wires twisted together.
[0014] Preferably, the material of the first rope is ultra-high molecular weight polyethylene.
[0015] Preferably, the second rope is made of aramid fiber.
[0016] Preferably, the material of the third rope is carbon fiber.
[0017] Preferably, the material of the fourth rope is PBO fiber.
[0018] Preferably, the material of the fifth rope is basalt fiber.

[0020] Preferably, the first and second filling layers are made of polystyrene foam.
[0021] Preferably, both the wire harness layer and the protective layer are made of neoprene rubber.
[0022] The beneficial effects of this utility model are:
[0023] By using a variety of high-strength materials as components of the cable, such as ultra-high molecular weight polyethylene, aramid fiber, carbon fiber, PBO fiber, basalt fiber, and glass fiber, the cable body has excellent tensile strength, capable of withstanding large tensile forces without easily breaking. At the same time, the addition of filler layer one and filler layer two effectively improves the overall tightness and stability of the cable, further enhancing its tensile strength. In addition, the neoprene rubber bundle layer and protective layer not only have good wear resistance and flame retardancy, but are also oil-resistant and low-temperature resistant, thereby extending the service life of the cable and improving its application range.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0032] Reference Figure 1-4 A high-strength tensile composite cable includes a cable body 1, the cable body 1 includes a protective layer 12 and multiple cable cores 11, and the multiple cable cores 11 are arranged in a twisted manner, and the protective layer 12 is disposed on the outside of the multiple cable cores 11.
[0033] The cable core 11 includes a tensile core wire 111, rope 112, rope 213, rope 314, rope 415, rope 516, rope 617 and a bundle layer 118. Ropes 112, 213, 314, 415, 516 and 617 are arranged in a twisted manner around the tensile core wire 111, and the bundle layer 118 is located outside ropes 112, 213, 314, 415, 516 and 617.
[0034] A second filling layer 14 is provided in the gaps between multiple cable cores 11, and a first filling layer 13 is provided in the gaps between multiple cable cores 11 and the protective layer 12.
[0035] The twisting direction of multiple cable cores 11 is opposite to the twisting direction of ropes 112, 113, 114, 115, 116 and 117 on the tensile core wire 111, that is, one adopts left twisting and the other adopts right twisting.
[0036] In this embodiment, in order to provide the cable body 1 with high tensile strength without affecting its normal bending performance, the tensile core wire 111 is made of multiple bundles of steel wires twisted together.
[0037] Rope 112 is made of ultra-high molecular weight polyethylene, rope 213 is made of aramid fiber, rope 314 is made of carbon fiber, rope 415 is made of PBO fiber, rope 516 is made of basalt fiber, and rope 617 is made of glass fiber.
[0038] Ultra-high molecular weight polyethylene, aramid fiber, carbon fiber, PBO fiber, basalt fiber, and glass fiber all have good anti-aging, high temperature resistance, low temperature resistance, tensile strength, and pollution resistance, which can effectively improve the overall tensile performance of the cable body 1. At the same time, even if the protective layer 12 and the bundle layer 118 are partially damaged during the use of the cable body 11, it can still maintain good tensile performance, thereby greatly improving the safety during use.
[0039] In this embodiment, the filler layer 13 and filler layer 14 are made of polystyrene foam. Polystyrene foam is a closed-cell foam plastic containing a large number of tiny closed pores. When subjected to external impact, these pores can be compressed, and the compressibility of air can be used to absorb and disperse energy, thereby playing a buffering role. At the same time, it has low cost and good heat insulation and buoyancy.
[0040] In this embodiment, both the cable layer 118 and the protective layer 12 are made of neoprene rubber, which has excellent wear resistance and flammability, good oil resistance, and excellent low-temperature performance. At the same time, the cable layer 118 can also effectively provide good protection for rope 112, rope 213, rope 314, rope 415, rope 516 and rope 617.

Meanwhile, the inclusion of filler layer 13 and filler layer 2 14 effectively improves the overall tightness and stability of the cable, further enhancing its tensile strength. Furthermore, the neoprene rubber binding layer 118 and protective layer 12 not only possess good wear resistance and flame retardancy but also oil resistance and low-temperature resistance, thus extending the cable's service life. It is suitable for various high-intensity, high-requirement applications, such as marine engineering, construction sites, and hoisting operations, demonstrating high practical value.
