[0029] Example

[0030] like Figures 1-4 As shown, this utility model provides a technical solution: a three-in-one combined tensile and wear-resistant coiled cable, which includes, from the outside to the inside, an insulation protection layer 1, a tensile protection layer 2, a composite braided protection layer 3, a separation structure, and a battery core assembly, etc. The various layers work closely together to ensure the stable operation of the cable under complex working conditions and meet the various performance requirements of port cranes and other equipment for cables.

[0031] The insulating protective layer 1 is made of polyetheretherketone (PEEK). PEEK has excellent insulation properties, which can effectively prevent current leakage and ensure the safety of power transmission. At the same time, it also has good chemical corrosion resistance, high temperature resistance and mechanical properties. In harsh environments such as ports, it can resist the erosion of various chemicals and the effects of high temperature and high humidity, providing a reliable first line of protection for the internal cable structure.

[0032] The tensile protective layer 2 is made of aramid fiber. Aramid fiber has extremely high strength and modulus, and its tensile strength far exceeds that of ordinary fiber materials. When the cable is subjected to tensile force, aramid fiber can effectively bear the tensile force, prevent the cable from being pulled apart, and ensure that the cable maintains structural integrity during the frequent winding and stretching process of port cranes, thus maintaining stable power and signal transmission.

[0033] The composite braided protective layer 3 includes a first braided filament 4, a second braided filament 5, and a third braided filament 6, which are interwoven and intertwined.

[0034] The material of the first braided wire 4 is stainless steel wire, accounting for 40%, and the stainless steel wire has good strength and corrosion resistance, plays an important role in the wear resistance and tensile resistance of the cable, and its high strength can enhance the tensile resistance of the cable as a whole, and the corrosion resistance of stainless steel can resist the erosion of moisture, salt and other substances in the external environment, prolonging the service life of the cable. In the port environment, there are more seawater, humid air and various corrosive substances, and the stainless steel wire can effectively protect the internal structure of the cable.

[0035] The material of the second braided wire 5 is Kevlar fiber, accounting for 30%, and the Kevlar fiber has the advantages of high strength, high modulus and low density, and its high strength characteristics further enhance the tensile resistance of the cable, which can withstand greater tension without breaking, and at the same time, the low density characteristics of Kevlar fiber make the cable not too heavy under the premise of ensuring strength, facilitating winding and installation operation. In the winding process of the port crane, Kevlar fiber can ensure that the internal structure is not damaged when the cable is repeatedly bent and stretched.

[0036] The material of the third braided wire 6 is glass fiber, accounting for 30%, and the glass fiber has good insulation performance and wear resistance, which can enhance the overall insulation effect of the cable, and at the same time, when the cable rubs with external objects, it plays a role in wear resistance, protecting the internal structure. In the daily use of the cable, it may rub with other parts of the port equipment, and the glass fiber can effectively reduce the damage caused by such friction to the cable, maintaining the normal operation of the cable.

[0037] The separation structure includes an inner sleeve 7, a plurality of separation layers 8 and an outer sleeve 9.

[0038] The outer sleeve 9 is arranged inside the third braided wire 6, and the material thereof is ceramicized silicone rubber. The ceramicized silicone rubber has the elasticity and softness of rubber at room temperature, facilitating the winding and installation operation of the cable, and when it encounters high temperature, it can quickly transform into a hard ceramic-like substance, forming a layer of high-temperature-resistant and heat-insulating protective layer, effectively preventing the spread of flames and improving the flame retardant performance of the cable. In the event of a fire or other emergency in the port, the ceramicized silicone rubber outer sleeve 9 can provide critical fire protection for the internal structure of the cable, ensuring the continuity of power and signal transmission, and reducing safety risks.

[0039] Several separation layers 8 are arranged between the outer sleeve 9 and the inner sleeve 7, also made of ceramicized silicone rubber, and are integrally designed with the outer sleeve 9 and the inner sleeve 7. The separation layers 8 separate different battery components and prevent mutual friction and collision between the batteries. The separation layers 8 also have certain insulation and flame retardation effects. During long-term use of the cable, the battery components may be displaced due to vibration, bending, and other reasons. Without the protection of the separation layers 8, short circuits may occur between the batteries, affecting the normal operation of the cable. The integrally designed ceramicized silicone rubber separation layers 8 can ensure the stability and integrity of the structure and improve the reliability of the cable.

[0040] The inner sleeve 7 further comprises a reinforcing layer 14 fixedly connected between the inner sleeve 7 and the reinforcing layer 14. The inner sleeve 7 is made of ceramicized silicone rubber and mainly serves to protect the internal battery components and the reinforcing layer 14, and to provide support for the separation layers 8. The reinforcing layer 14 is made of polyoxymethylene, which has high strength and rigidity and can provide central support for the cable to enhance the overall structural stability of the cable, prevent the cable from twisting and deforming during winding and stretching, and ensure the stable and reliable transmission of power and signals.

[0041] The battery component comprises an outer protective layer 10, an inner protective layer 11, and a battery body 12.

[0042] The outer protective layer 10 is made of mica tape, which has good high-temperature resistance and insulation performance. When the cable is subjected to high temperatures, the mica tape can effectively protect the battery body 12 from high-temperature effects, maintain the normal working state of the battery, prevent short circuits or damage to the battery caused by high temperatures, and ensure the stability and safety of power transmission.

[0043] The inner protective layer 11 is made of polyvinyl chloride (PVC), which has good insulation performance and flexibility. The inner protective layer 11 can further protect the battery body 12, adapt to the deformation of the battery during bending and winding of the cable, prevent the battery from being damaged by external pressure, and ensure the reliability of power transmission.

[0044] The battery body 12 is the core part of the cable for transmitting power and signals. The design of the various protective layers ensures that the battery body 12 can work normally under various complex working conditions.

[0045] The space between the battery components and the separation structure is filled with shock-absorbing filler 13, which is made of silicone foam. The silicone foam has good elasticity and shock-absorbing performance. When the cable is subjected to external forces such as vibration and impact, the silicone foam can effectively absorb and disperse energy, reduce damage to the battery components and other internal structures, protect the integrity and stability of the cable, prolong the service life of the cable, and ensure the stability of power and signal transmission.

[0046] Principle: In the operation process of port crane and other equipment, the three-in-one combined anti-tension wear-resistant winding cable starts to work. Firstly, the insulating protective layer 1 prevents current leakage to ensure the safety of power transmission. When the cable is subjected to tensile force, the aramid fiber of the anti-tension protective layer 2 bears the main tensile force, and the stainless steel wire, Kevlar fiber and glass fiber in the composite braided protective layer 3 further enhance the anti-tension and wear-resistant performance, and protect the internal structure. In the winding process, the flexibility and strength of each layer structure ensure that the cable can be bent smoothly without damage. If high temperature environment is encountered, the ceramicized silicone rubber sheath 9 and the separation layer 8 will quickly transform into ceramic state to play the role of flame-retardant and heat-insulating, protecting the internal core assembly. The outer protective layer 10 mica tape and the inner protective layer 11 polyvinyl chloride and the shock absorbing filler 13 silicone foam together protect the core body 12, so that it can work normally under vibration, impact and other conditions, and stably transmit power and signal, thereby providing reliable power and signal transmission guarantee for the operation of port equipment, reducing equipment maintenance cost and safety risk, and improving production efficiency and economic benefit.

[0047] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
