Detailed Implementation

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] like Figures 1-2 As shown, a multi-core composite lifting wire rope includes a multi-strand inner core 1, a fiber winding layer 4, and composite steel strands 5. Two multi-strand inner cores 1 are provided, and the two multi-strand inner cores 1, along with a first optical fiber 2 and a second optical fiber 3, are twisted together to form a composite inner core layer. The multi-strand inner core 1 and the first optical fiber 2 and second optical fiber 3 are wrapped with a fiber winding layer 4. The multi-strand inner core 1 includes a thickened inner core 101 and polyethylene fibers 102. The multi-strand inner core 1 is constructed by twisting thirteen polyethylene fibers 102 around a thickened inner core 101. It also includes outer steel strands 103, with the outer steel strands 103 spirally twisted around the outer side of the polyethylene fiber 102, and nine outer steel strands 103 are provided; the fiber winding layer 4 protects the composite inner core layer composed of two multi-strand inner cores 1, the first optical fiber 2, and the second optical fiber 3, which not only ensures the strength of the wire rope, but also ensures the stability and reliability of the signal in long-distance transmission. The multi-strand inner core 1 is composed of a thickened inner core 101, polyethylene fiber 102, and outer steel strands 103, and has good wear resistance, fatigue resistance, and extrusion resistance.

[0021] like Figures 1-2 As shown, a composite steel strand 5 is provided on the outer side of the fiber winding layer 4, and there are thirteen composite steel strands 5 twisted into a composite steel strand layer. The composite steel strand 5 includes a galvanized inner core 501 and a polyethylene outer core 502, and the composite steel strand 5 is formed by twisting seven polyethylene fibers 102 around a galvanized inner core 501. The outer strand 6 is specifically a single strand of composite fiber core, and there are thirteen outer strands 6. The outer strand 6 and the composite steel strand 5 are in line contact or in a compacted strand structure. The composite steel strands 5 on the outer side of the composite core layer are thirteen twisted into a composite steel strand layer. The composite steel strand layer enhances the compressive and tensile strength of the wire rope. The composite steel strand 5 is composed of a galvanized inner core 501 and a polyethylene outer core 502, resulting in a stable structure and good support. The outer layer 6, made of composite fiber core strands, is located on the outside of the composite steel strand 5. This reduces wear on the wire rope. It can bond very tightly to the composite steel strand 5 internally and fill the gap between the composite steel strand 5 and the first wrapping layer 7 externally, reducing friction between them. This results in good stability and performance.

[0022] like Figure 1 and Figure 3 As shown, the outer layer of the composite steel strand 5 is provided with an outer strand 6, and the outer layer of the outer strand 6 is provided with a first wrapping layer 7. A thin steel wire 8 is twisted around the outside of the first wrapping layer 7, and a second wrapping layer 9 is provided around the outside of the thin steel wire 8. The outer surface of the first wrapping layer 7 is coated with a flame-retardant coating, while the outer surface of the second wrapping layer 9 is coated with an anti-corrosion coating. The structure of the thin steel wire 8 twisted around the outside of the first wrapping layer 7 is simple and can improve the strength and toughness of the wire rope, thereby increasing the working safety factor. The double-layer structure of the first wrapping layer 7 and the second wrapping layer 9 can play an effective protective role and has good wear resistance and corrosion resistance.

[0023] In summary, as Figures 1-3 As shown, this lifting wire rope based on a multi-core composite structure, in use, firstly, two multi-strand inner cores 1, along with the first optical fiber 2 and the second optical fiber 3, are twisted together to form a composite inner core layer. While lifting heavy objects, the lifting wire rope needs to measure the weight of the goods, test the temperature, transmit information, and control signals. This requires a high-strength, tensile-resistant fiber optic wire rope capable of transmitting information. The fiber winding layer 4 protects the composite inner core layer composed of the two multi-strand inner cores 1, the first optical fiber 2, and the second optical fiber 3, ensuring both the strength of the wire rope and the stability and reliability of the signal during long-distance transmission. The multi-strand inner core 1 consists of a thickened inner core 101, polyethylene fiber 102, and outer steel strands 103, exhibiting good wear resistance, fatigue resistance, and compression resistance. During use, thirteen composite steel strands 5 are twisted together on the outer side of the composite inner core layer to form a composite steel strand layer, which can... The composite steel strand 5, composed of a galvanized inner core 501 and a polyethylene outer core 502, enhances the compressive and tensile strength of the wire rope, providing structural stability and good support. The outer layer 6, made of a single strand of composite fiber core, reduces wear on the wire rope. It integrates tightly with the composite steel strand 5 internally and fills the gap between the composite steel strand 5 and the first wrapping layer 7 externally, reducing friction between them. This results in good stability and performance. The first wrapping layer 7 has a simple structure with a coil of fine steel wire 8 twisted around it, improving the strength and toughness of the wire rope and increasing the safety factor. The double-layer structure of the first and second wrapping layers 7 provides effective protection. This completes the application process of the multi-core composite lifting wire rope.
