[0022] Step 1: Prepare the cores, including the following steps:

[0023] 1.1) Prepare the power core: Use a stranding machine to form a stranded structure by stranding multiple bare metal wires in a regular stranding pattern of 1 + 6 + 12, with a stranding pitch - diameter ratio of 12 times and a left - hand stranding direction; then use a wrapping machine to wrap the non - woven fabric around the outer wall of the stranded structure in a right - hand direction to form a circular cross - section; finally, use an extrusion machine to extrude an irradiated cross - linked polyethylene material on the outer wall of the stranded structure to form a power conducting core insulating layer, completing the preparation of the insulated power core.

[0024] 1.2), Preparation of the control core wire: Multiple bare metal wires are formed into a control core wire by a stranding machine using the regular stranding method of 1 + 6. The stranding pitch diameter ratio is 6 times, and the stranding direction is right-handed; then, an irradiated cross-linked polyethylene material is extruded onto the outer wall of the control core wire by an extrusion machine to form a control core wire insulation layer, completing the preparation of the insulated control core wire;

[0025] Step 2, Preparation of the cable core: Multiple of the power core wires and multiple of the control core wires are arranged tangentially to each other in pairs, and are stranded with each other by a stranding machine to form a stranded structure. A Kevlar fiber filling rope with a circular cross-section is filled in the gaps of the stranded structure. Finally, a non-woven fabric tape is wound around the outer wall of the filling rope in the right-handed direction to form the cable core into a circular cross-section;

[0026] Step 3, Preparation of the inner liner: A cross-linked polyethylene material is extruded onto the outer wall of the cable core by an extrusion machine to form an inner liner with a thickness of 0.2 - 0.4 mm;

[0027] Step 4, Preparation of the strengthening layer, including the following steps:

[0028] 4.1), Preparation of the Kevlar fiber braided tape: Multiple strands of Kevlar fiber are woven by a braiding machine in a cross-braiding manner along the length direction of the braided tape to form a Kevlar fiber braided tape with a certain width;

[0029] 4.2), Preparation of the composite tape: Multiple parallel distributed compressive cores are added at equal intervals along the width direction of the Kevlar fiber braided tape. Each compressive core extends along the length direction of the Kevlar fiber braided tape. Adjacent two compressive cores are woven and connected by the Kevlar fiber braided tape, and together with the Kevlar fiber braided tape, are woven by a braiding machine to form a composite tape;

[0030] 4.3), Wrapping the composite tape: The composite tape is spirally wrapped around the outer wall of the inner liner 4 along the length direction of the cable core by a wrapping machine. The wrapping direction is right-handed, and the wrapping overlap rate is ≥ 20%;

[0035] Compared with the prior art, the significantly advantageous features of the anti-tensile, wear-resistant, and anti-winding drum cable for mobile equipment proposed by the present invention are as follows:

[0036] 1. By combining the compression core with Kevlar, first, multiple strands of Kevlar are woven into a Kevlar woven tape by a weaving machine, then multiple compression cores are connected to multiple Kevlar woven tapes by a weaving machine, and then the compression cores and the Kevlar woven tapes are woven and connected to form a composite strip, which is wound around the outer wall of the inner liner to form a strengthening layer, making the cable more resistant to tensile and torsional forces. Moreover, by using the spiral structure formed by winding the compression core, the cable has radial compressive performance and can resist the damage caused by tensile force and external extrusion force during the cable winding process;

[0037] 2. The outer sheath is made of polyurethane elastomer and is extruded around the outer wall of the strengthening layer by an extruder suitable for elastomers. The polyurethane elastomer material has excellent mechanical properties, high elastic properties, wear resistance, high tear resistance, and tensile strength. Being extruded around the outer wall of the strengthening layer as the outer sheath makes the cable outer sheath have good wear and tear resistance and is not prone to sheath cracking problems due to frequent winding or dragging;

[0038] 3. The wrapping tape, wrapping layer, and strengthening layer are all wrapped in the same direction, reducing the outer diameter of the core, strengthening the structural strength of the cable, and making the cable more flexible with good bending flexibility.

[0046] In order to better understand the technical content of the present invention, specific embodiments are hereby given and described in conjunction with the accompanying drawings as follows.

[0047]

Tensile, wear-resistant and anti-winding drum cable for mobile equipment

[0048] Combined with Figures 1-4 As shown, the tensile, wear-resistant and anti-winding drum cable for mobile equipment according to the embodiments of the present invention includes a core 1, a filling rope 2, a wrapping layer 3, an inner lining layer 4, a strengthening layer 5 and an outer sheath 6.

[0049] Among them, the core 1 includes a plurality of power cores 11 and a plurality of control cores 12 that are tangent to each other in pairs and intertwined. In the figure, 3 power cores 11 and 3 control cores 12 are taken as examples for illustrative purposes.

[0050] Specifically, a plurality of power cores 11 are arranged tangent to each other at 120° around the axis, and a plurality of control cores 12 are arranged between adjacent two power cores 11 and are tangent to the power cores 11.

[0051] Furthermore, the power core 11 includes a plurality of power conductor cores 111 that are tangent to each other and intertwined, the outer wall of the power conductor core 111 is wrapped with a wrapping tape 112, and the outer wall of the wrapping tape 112 is extruded with an insulation layer 113 of the power conductor core.

[0052] In an optional embodiment, a Kevlar filling rope is filled in the gap of the intertwined structure of the plurality of power conductor cores 111 that are tangent to each other and intertwined, so that the intertwined structure of the power conductor cores 111 can be wound and fixed by the wrapping tape 112 to form a circular cross-section.

[0053] Specifically, the power conductor core 111 is generally formed by stranding tinned copper wires. It adopts a regular stranding method of 1+6+12 to form a stranded structure, with a stranding pitch diameter ratio of 12 times and a left-handed stranding direction. The wrapping tape 112 is wrapped around to the right with non-woven fabric. The main purpose of its setting is to play a role in shaping, making the cross-section of the power core 11 more round after cabling. The power conductor core insulation layer 113 is extruded on the outer wall of the wrapping tape 112 with irradiated cross-linked polyethylene material through an extruder.

[0054] Furthermore, the control core 12 includes multiple control conductor cores 121 that are tangent to each other and stranded together. The outer wall of the control conductor core 121 is extruded with a control conductor core insulation layer 122.

[0055] Specifically, the control conductor core 121 is generally formed by stranding tinned copper wires. It adopts a regular stranding method of 1+6 to form a stranded structure, with a stranding pitch diameter ratio of 6 times and a right-handed stranding direction. The control conductor core insulation layer 122 is extruded on the outside of the stranded structure of the control conductor core 121 with irradiated cross-linked polyethylene material.

[0056] By controlling the left-handed stranding direction of the power conductor core 111 and the right-handed stranding direction of the control conductor core 121, the stranding directions of the power conductor core 111 and the control conductor core 121 are opposite, making the cabled cable softer.

[0057] In the illustration, 4 power conductor cores 111 and 4 control conductor cores 121 are taken as examples for exemplary description.

[0058] As Figure 1 shown, the filling cord 2 is filled in the stranding gap between the power core 11 and the control core 12, and together with the power core 11 and the control core 12, it is wound and fixed by the wrapping layer 3 to form a circular cross-section.

[0059] Among them, the filling cord 2 uses a Kevlar filling cord with a circular cross-section. Kevlar has high strength, good flexibility, and good anti-cutting and tensile properties. As a filling cord filled in the stranding gap of the core 1, it not only makes the cross-section of the cabled cable more round, but also enables the cable to have flexibility while maintaining high tensile properties.

[0060] Furthermore, the wrapping layer 3 is wrapped with non-woven fabric. The non-woven fabric has the advantages of light weight and softness. Specifically, a thin non-woven fabric with a thickness of 0.15 mm and a width of 55 mm is used. The wrapping overlap rate of the non-woven fabric is 20%-30%. In order to reduce the cable diameter of cabling, the wrapping direction of the non-woven fabric is the same as the wrapping direction of the wrapping tape 112. In this embodiment, right-handed wrapping can be adopted.

[0061] As Figures 1-3 shown, the inner lining layer 4 is extruded on the outer wall of the wrapping layer 3.

[0062] Furthermore, the inner liner layer 4 is made by extrusion of cross-linked polyethylene with an extrusion thickness of 0.2 - 0.4 mm. Cross-linked polyethylene has good heat resistance, corrosion resistance, and heat insulation properties, and also has good pressure resistance. It can be bent arbitrarily without brittle cracking and has a high creep resistance strength. As the inner liner layer 4 is extruded on the outer wall of the wrapping layer 3, it can prevent the metal reinforcement layer from piercing the insulation under the bending state of the cable and plays a protective role for the conductor 1.

[0063] As Figure 4 shown, the reinforcement layer 5 includes a Kevlar wire braided tape 52 and at least two layers of compression cores 51. The compression cores 51 are arranged parallel to the length direction of the Kevlar wire braided tape 52 and are braided and connected by the Kevlar wire braided tape 52 to form a composite tape. The composite tape is wrapped around the outer wall of the inner liner layer 4 along the length direction of the cable.

[0064] Among them, the braiding method of the composite tape is as follows: First, a multi-strand Kevlar wire is braided into a Kevlar wire braided tape by a braiding machine. During the braiding process, multiple parallel steel wires are added equidistantly along the width direction of the braided tape. Each steel wire extends along the length direction of the braided tape, and adjacent two steel wires are braided and connected by the braided tape. Together with the braided tape, they are braided by the braiding machine to form a composite tape.

[0065] Specifically, as Figure 4 shown, the composite tape is arranged in an alternating structure of Kevlar wire braided tape 52 - compression core 51 - Kevlar wire braided tape 52 - compression core 51 - Kevlar wire braided tape 52 in sequence along the width direction of the composite tape, forming an alternating multi-layer structure.

[0066] In an alternative embodiment, the lapping rate of the composite tape during wrapping is ≧20%. The wrapping direction is the same as that of the wrapping layer 3 and the wrapping tape 112, both are right-handed wrapping. The same-direction wrapping can improve the flexibility of the cable after stranding and facilitate the bending and laying of the cable. The braiding density of the Kevlar wire braided tape 52 is 85% - 95%, the included angle between the Kevlar wire braided filaments in the braided tape and the cable axis is ≤30°, the outer diameter of the compression core 51 is 2.5 - 6 mm, and the wrapping pitch ratio of the compression core 51 is 8 - 12 times.

[0067] In a specific embodiment, as Figure 1 and Figure 4 shown, the compression core 51 includes six round-section steel wires extending along the length direction of the Kevlar wire braided tape 52. The six steel wires are arranged equidistantly and parallel along the width direction of the Kevlar wire braided tape 52. The steel wires have high tensile strength and mechanical strength and can withstand radial pressure. As the compression core 51, they are braided in the Kevlar braided tape 52 and wrapped around the outer wall of the inner liner layer 4 along the length direction of the cable with the Kevlar braided tape, forming a spiral structure distributed around the cable axis. The radial compression is achieved through the spiral structure, and a radial compression protection effect is provided for the conductor.

[0068] In this embodiment, a steel wire rope is added to the braided structure of the Kevlar braided tape 52 and wrapped around the outer wall of the inner liner layer 4 together with the braided tape to form a reinforcing layer 5, so that the cable has good axial tensile resistance and radial compressive resistance after stranding.

[0069] Specifically, Kevlar has high strength and good flexibility, with good anti-cutting and tensile properties. After being braided into a tape, it has good tensile resistance and bending resistance; the steel wire rope has good radial compressive resistance and is wrapped around the outer wall of the inner liner layer 4 to form a spiral structure. The radial compression is achieved through the spiral structure, so that the cable has good radial compressive resistance after stranding.

[0070] In combination with the above embodiments, in this embodiment, a composite tape formed by combining a steel wire rope and a Kevlar braided tape 52 is used. Utilizing the tensile resistance of the Kevlar braided tape 52, multiple steel wire ropes are braided and connected together. Through small-angle and high-density braiding, the deformation of the spiral structure formed by the compression-resistant core 51 in the length direction is restricted, and then the pitch of the spiral structure formed by the steel wire rope wrapped around the outer wall of the inner liner layer 4 is restricted, avoiding the deformation of the spiral pitch under the action of the tensile force, improving the stability and reliability of the spiral structure, and the spiral structure has good bending and torsion resistance. As a cable structure added to the cable, it will not affect the normal laying of the cable.

[0071] Furthermore, for the outer sheath 6, a polyurethane elastomer is extruded and wrapped around the outer wall of the reinforcing layer 5 by an extruder suitable for elastomers, and the extrusion thickness is 2.0 - 2.6 mm; the polyurethane elastomer material has excellent mechanical properties, high elastic properties, wear resistance, high tear resistance and tensile strength. Being extruded and wrapped around the outer wall of the reinforcing layer 5 as the outer sheath can play a good protective role for the cable.
