Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a halogen-free, wear-resistant and torsion-resistant high-strength winding cable. Background Art

[0002] At present, most of the coiled cables on the market are ordinary cables with simple structure and average performance. However, many places such as wind power generation and outdoor mobile motor systems are mostly in areas with relatively harsh climatic conditions, generally in northern my country, where the climate is relatively cold and the temperature difference between day and night is large. The cables also need to be bent and twisted frequently. In view of this phenomenon, twist-resistant, high-strength, and weather-resistant coiled cables are required;

[0003] Among them, the "halogen-free wear-resistant, torsion-resistant, high-strength fire alarm cable" disclosed by the application number "CN216749364U" is also an increasingly mature technology, which "includes a cable core, a sheath layer, a thin steel wire and copper wire braided shielding layer, and a sheath layer sequentially set up outside the cable core; the cable core is formed by twisting a plurality of cores, and the cores are filled with high-temperature flame-retardant filling ropes, and the conductor is formed by twisting a plurality of conductor monofilaments and a plurality of aramid wires. The utility model adds high-strength aramid wires to the conductor to enhance the strength of the conductor, selects fluoroplastics with excellent performance as cable insulation, and uses halogen-free polyurethane as a cable sheath, which can greatly improve the life of the cable, and adopts a mixed braiding of thin steel wire and copper wire. This braiding structure can not only play a shielding role, shielding the remaining interference current, but also serve as a reinforcement layer to improve the cable's compressive strength, and can be used in harsh environments. In the event of a fire, it ensures that the power supply line of the automatic alarm system and the fire linkage control line continue to work, and will not cause flame extension, providing a guarantee for people to escape and put out fires.

[0004] However, the above-mentioned fire alarm cable design has the following disadvantages: during long-term use, the fire alarm cable will age and reduce its service life, and it is easy to break in extreme weather, affecting communication use. Utility Model Content

[0025] like Figure 1-Figure 3 As shown, the utility model proposes a halogen-free wear-resistant and torsion-resistant high-strength winding cable, comprising a winding protective layer 1, a wear-resistant mechanism 2 is arranged inside the winding protective layer 1, and an anti-torsion mechanism 3 is arranged inside the wear-resistant mechanism 2;

[0026] A protection mechanism 4 is arranged inside the anti-torsion mechanism 3 .

[0027] The wear-resistant structure 2 includes a first wear-resistant layer 201 arranged on the inner side of the winding protective layer 1, a second wear-resistant layer 202 is arranged on the inner side of the first wear-resistant layer 201, a tear-resistant layer 203 is arranged on the inner side of the second wear-resistant layer 202, and a reinforcement layer 204 is arranged on the inner side of the tear-resistant layer 203.

[0028] During specific use, the cooperation between the first wear-resistant layer 201 and the second wear-resistant layer 202 facilitates the protection of the wound cable when it is wound or used. At the same time, the anti-tear layer 203 is used to protect the wound cable to avoid breakage when the wound cable is wound up, and the fiber core inside the wound cable is protected. The reinforcement layer 204 is used to improve the firmness of the wound cable to avoid breakage.

[0029] The anti-torsion mechanism 3 includes a plurality of middle sheath layers 301 arranged inside the reinforcement layer 204 , two sheaths 302 are arranged inside each middle sheath layer 301 , a plurality of bundle tubes 303 are arranged inside the sheath 302 , and an anti-torsion cable 304 is arranged around the middle of the bundle tube 303 .

[0030] During specific use, the protective mechanism 4 is protected by the middle sheath layer 301 and the sheath 302, and the strength of the wound cable is improved. At the same time, the anti-torsion cable 304 is wound by the bundle tube 303, and the strength of the anti-torsion cable 304 inside the wound cable is improved.

[0031] The protection mechanism 4 includes an outer sheath layer 401 arranged on the inner side of several middle sheath layers 301, a reinforced shielding layer 402 arranged on the inner side of the outer sheath layer 401, several wear-resistant insulating layers 403 arranged on the inner side of the reinforced shielding layer 402, a first aramid wire conductor 404 arranged inside each wear-resistant insulating layer 403, a torsion-resistant insulating layer 405 arranged on the side of the wear-resistant insulating layer 403, a second aramid wire conductor 406 arranged inside the torsion-resistant insulating layer 405, an inner sheath is filled between the outer sides of the wear-resistant insulating layer 403 and the torsion-resistant insulating layer 405 and the outer sheath layer 401, an anti-interference layer 407 arranged in the middle between the outer sheath layers 401, and a reinforcement 408 arranged inside the anti-interference layer 407.

[0032] During specific use, the cables inside the protection mechanism 4 are protected by the outer sheath layer 401, and the reinforced shielding layer 402 is used to shield external interference when transmitting the optical fiber inside the wound cable, thereby ensuring that the cable can transmit information normally. The wear-resistant insulation layer 403 and the torsion-resistant insulation layer 405 are used to insulate and protect the cables inside the wound cable to avoid damage to the cables in the event of a fire. High-strength aramid wire is added as a reinforcing element when the first aramid wire conductor 404 and the second aramid wire conductor 406 are twisted. Aramid wire has the characteristics of high toughness, high strength, and small weight, which can increase the tensile strength and softness of the conductor, improve the flexibility of the wound cable, and prevent breakage.

[0033] The wear-resistant insulating layer 403 and the torsion-resistant insulating layer 405 are made of fluoroplastic material.

[0034] When used specifically, the wear-resistant insulating layer 403 and the torsion-resistant insulating layer 405 are made of fluoroplastic material, and are almost unaffected by temperature changes, have excellent weathering resistance and mechanical strength, and are not affected by various acids, alkalis and organic solvents. Therefore, they are suitable for environments with large climate changes and corrosive occasions.

[0035] The inner sheath 406 is formed by weaving a mixture of fine steel wires and copper wires.

[0036] During specific use, the inner protective layer 406 is used to extrude a layer of wear-resistant and oil-resistant nitrile sheath on the outside of the cable, while ensuring the normal operation of the cable in an oily environment.

[0037] The outer sheath layer 401 is made of flame-retardant halogen-free thermoplastic polyurethane sheath material, and the reinforcement member 408 is made of soft steel wire with a diameter of 2.5 mm to 4 mm.

[0038] When used specifically, the outer sheath layer 401 is used as the sheath material of the wound cable, which can effectively protect the cable so that it can operate normally for a long time even in harsh environments and under frequent winding and bending.

[0039] Supplementary explanation: Middle sheath layer 301: A layer of wear-resistant and oil-resistant nitrile sheath should be extruded outside the cable core to ensure the normal operation of the cable in an oily environment.

[0040] Strengthen the shielding layer 402: The inner protection is braided with fine steel wire and copper wire. This braided structure can not only play a shielding role, but also serve as a strengthening and wear-resistant layer to improve the cable's compression, tension and wear resistance.

[0041] Sheath 302: Sheath 302 is extruded from flame-retardant halogen-free thermoplastic polyurethane sheath material. The polyurethane material has the softness and wear resistance of rubber, and the processing technology is simple. It can be directly extruded by heating. Its molecular structure is generally composed of soft segments and rigid segments. Due to the existence of these two segments, the polyurethane material has higher tensile strength, better wear resistance, resistance to corrosion by various oils and solvents, and resistance to electronic radiation. The flame-retardant halogen-free thermoplastic polyurethane sheath material also has the characteristics of flame retardancy and halogen-free. As the sheath material of the wound cable, it can effectively protect the cable and ensure long-term normal operation even in harsh environments and under frequent winding and bending.

[0042] The reeled cable can meet the harsh operating environments of wind power, outdoor overhead cranes, etc., and is highly wear-resistant and tensile-resistant, avoiding the risk of power outages due to cable breakage or wear, and the shutdown of special equipment such as overhead cranes, drums, conveyors and conveyors, thereby avoiding the occurrence of safety accidents. The structural design of adding high-strength aramid wire to the conductor enhances the strength of the conductor, but does not have a significant impact on the weight of the conductor; soft round steel wire is added in the middle to improve the overall tensile strength of the cable and avoid the cable conductive core being broken due to long-term suspension of the cable; a layer of wear-resistant and oil-resistant nitrile sheath is used to improve the softness and wear resistance of the cable, while greatly improving the acid and alkali resistance and waterproof performance of the cable; the mixed weaving of fine steel wire and copper wire can not only play a shielding role to shield the remaining interference current, but also serve as a reinforcement layer to improve the compression and tensile resistance of the cable. The selection of excellent performance fluoroplastics as cable insulation and halogen-free polyurethane as cable sheath can greatly increase the service life of the cable, and will not produce halogen gas harmful to the human body in the event of a fire. The overall structure enables the cable to have a long working life, with excellent oil resistance, good toughness, wear resistance, cold resistance (low temperature resistance), aging resistance, acid and alkali resistance, climate resistance, long service life, UV resistance and energy release and many other excellent functions.
