[0011] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a vertically suspended cable.

[0012] This utility model is achieved through the following technical solution:

[0013] A vertical hoisting cable includes several groups of power cores and several groups of control cores. The control cores are twisted together in groups, and polyester tape is wrapped around the twisted control cores and tied tightly. A composite shielding layer is formed by overlapping soft copper tape and braiding fine copper wires in sequence outside the polyester tape. The power cores and control cores are twisted together to form a cable core. A tensile element is placed in the center of the cable core. A TPU elastomer inner sheath is extruded on the outside of the cable core. An aramid fiber braided reinforcement layer is woven on the outside of the TPU elastomer inner sheath. A TPU elastomer outer sheath is extruded on the outside of the aramid fiber braided reinforcement layer.

[0014] Both the power core and the control core include conductors, and a TPE thermoplastic elastomer insulation layer is extruded over the conductors.

[0015] The conductor is made of multiple strands of fine copper wire twisted together.

[0016] The conductor has an aramid filament placed at its center during stranding.

[0017] After the cable core is stranded, a layer of wrapping tape is loosely wrapped around the outside of the cable core and tied tightly. A layer of TPU elastomer inner sheath is first extruded over the wrapping tape. During the extrusion process, the loosely wrapped wrapping tape is removed, and the TPU elastomer inner sheath material is extruded into the gap of the cable core using an extruder to form a whole circle.

[0018] The tensile element is made of extruded aramid fiber filaments or steel wire rope with insulation.

[0019] The advantages of this utility model are as follows: The cable of this utility model comprises several power cores and several groups of control cores. The conductors are made of multi-strand fine copper wires twisted together, and the insulation is made of TPE thermoplastic elastomer extrusion. The control cores are twisted together in groups, and polyester tape is wrapped around the outside of the twisted control core groups and tied tightly. Soft copper tape is then wrapped around them in overlapping layers, and fine copper wire is braided on the outside to form a composite shielding layer. The power cores and control core groups are then twisted together to form a cable. A tensile element is placed at the center of the cable core. A layer of wrapping tape is loosely wrapped around the outside of the cable core and tied tightly. A layer of TPU elastomer sheath is extruded on the outside first. During extrusion, the loosely wrapped wrapping tape is removed, and the extrusion pressure of the extruder is used to squeeze the sheath material into the gaps of the cable core to form a complete circle. Then, an aramid fiber reinforcing layer is braided on the outside, and finally, a layer of TPU elastomer is extruded on the outside. This utility model has the characteristics of good flexibility, tensile strength, wear resistance, oil resistance, and aging resistance. Suitable for applications such as tower cranes, magnetic grabbers, stacker cranes, coiling machines, outdoor elevators, overhead cranes, and sewage treatment, where high requirements are placed on the tensile strength, wear resistance, weather resistance, oil resistance, and flexibility of cables.

[0023] Figure 4 This is a schematic diagram of the tensile element structure of this utility model. Detailed Implementation

[0024] like Figure 1 , 2 As shown in Figure 3, a vertical hoisting cable includes several groups of power cores 1 and several groups of control cores 2. The control cores 2 are twisted together in groups, and a polyester tape 3 is wrapped around the twisted control cores 2 and tied tightly. A composite shielding layer 4 is formed by overlapping soft copper tape and braiding fine copper wires on the outside of the polyester tape. The power cores 1 and control cores 2 are twisted together to form a cable core. A tensile element 5 is placed in the center of the cable core. A TPU elastomer inner sheath 6 is extruded on the outside of the cable core. An aramid fiber braided reinforcement layer 7 is woven on the outside of the TPU elastomer inner sheath 6. A TPU elastomer outer sheath 8 is extruded on the outside of the aramid fiber braided reinforcement layer 7.

[0025] Both the power core 1 and the control core 2 include a conductor 9, with a TPE thermoplastic elastomer insulation layer 10 extruded over the conductor 9. TPE is a polymer material combining the properties of plastics and rubber, possessing excellent processing performance, mechanical properties, weather resistance, and electrical properties. It can be directly extruded, resulting in a simple production process, high production efficiency, low cost, and low energy consumption, making it an excellent raw material for cable materials. Furthermore, TPE materials also exhibit good flexibility, abrasion resistance, weather resistance, and biocompatibility, giving them unique advantages in wire and cable insulation. The good flexibility and bending properties of TPE materials allow for flexible use of wires and cables in confined spaces or complex environments.

[0026] The conductor 9 is made of multiple strands of fine copper wire twisted together.

[0027] During stranding, an aramid filament is placed at the center of the conductor 9.

[0028] After the cable core is stranded, a layer of wrapping tape is loosely wrapped around it and then secured. A layer of TPU elastomer inner sheath is then extruded over the wrapping tape. During extrusion, the loosely wrapped tape is removed, and the TPU elastomer inner sheath material is extruded into the gaps in the cable core using an extruder to form a complete circle. This results in a cable with good roundness, less susceptibility to deformation and damage.

[0029] like Figure 4 As shown, the tensile element 5 is made of extruded aramid fiber filaments or steel wire rope with insulation. It provides good tensile strength and increases the tensile performance of the cable.

[0030] This utility model cable uses a Category 6+ multi-strand fine copper wire stranded soft conductor, ensuring that the cable has high flexibility and high conductivity. The Category 6+ multi-strand fine copper wire stranded soft conductor has the following properties:

[0031] Excellent flexibility: Because it is made of multiple strands of fine copper wire, this conductor has excellent flexibility and can adapt to various complex wiring environments.

[0032] Excellent electrical conductivity: Copper itself is a metal with excellent electrical conductivity, and the multi-strand structure further improves the conductivity of the conductor.

[0033] High corrosion resistance: The surface of copper wire is usually treated with anti-oxidation, which can effectively resist corrosive factors in the environment and extend the service life of the wire.

[0034] When conductors are stranded, aramid fibers are placed in the center to increase the strength of the conductors and provide effective tensile protection during repeated bending.

[0035] The insulation layer is made of TPE thermoplastic elastomer material, which has high electrical and mechanical properties. The control cores 2 are twisted together in groups, and a composite shielding layer of overlapping soft copper tape and fine copper wire braid is set on the outside of the control cores. The composite shielding structure makes the control cable more resistant to interference. The power core 1 and the control cores are twisted together to form a cable.

[0036] A tensile element is installed at the center of the cable core. The tensile element is made of extruded aramid fiber filaments or steel wire rope with insulation.

[0037] The sheath is made of TPU thermoplastic elastomer material. TPU has the same wear resistance, softness, and good weather resistance as rubber, giving the cable many excellent functions such as wear resistance, weather resistance, and softness. The sheath adopts a double-layer design, with an aramid fiber braided reinforcement layer in the middle of the double sheath. The inner sheath fills the gaps in the cable core with material through the extrusion pressure of the extrusion equipment to form a whole circle, making the overall structure of the cable more compact and stable. Through the design of each layer structure, the tensile strength, wear resistance, oil resistance, aging resistance, and flexibility of the cable are greatly improved to meet the requirements of corresponding scenarios.

[0038] Aramid fiber braided reinforcement is a high-performance reinforcing material widely used in various fields requiring high strength, high modulus, high temperature resistance, and corrosion resistance. Aramid fiber belongs to aromatic polymer materials and features high strength, high modulus, and excellent heat resistance.
