According to the heavy-load steel wire rope based on optical fiber communication, the traditional steel wire rope only has the characteristic of bearing tension, and the specially designed steel wire rope structure can simultaneously have the dual functions of built-in cable communication and bearing, but the signal transmission bandwidth is limited along with the influence of the length and the resistivity of a cable, and the signal transmission speed and the signal transmission quality cannot meet the requirements of a control system. However, with the expansion of the use of the steel wire rope, high-definition audio and video are carried out between the ground base station and the moving object, the requirement of large data transmission is more and more, and as the safety requirement of the heavy-load working condition is high, the detection and control functions are more, so that the requirement of large data transmission under the heavy-load working condition is more. The optical fiber communication is based on an optical transmission medium, the requirement for large data transmission can be met, but the problem of optical fiber arrangement in the heavy-duty steel wire rope is a great problem. Namely, the optical fiber for communication and the steel wire rope for bearing heavy load are designed into an integrated structure.

As shown in fig. 1, four strands of the reinforced sheathing member 1 are provided, and the core position where the four strands of the reinforced sheathing member 1 are wound provides a space for placing the optical fiber member 3. Through the structure, the steel wire rope has the advantages of high breaking tension, good wear resistance, no rotation, long-distance optical fiber communication, bearing and the like, and the four strands of reinforced cladding components 1 outside the optical fiber component 3 and the multilayer protective layers of the optical fiber component 3 prevent the internal optical fibers from being damaged due to physical and chemical factors, so that the effectiveness of signal transmission is ensured.
In an embodiment of the present disclosure, each reinforcing layer is composed of a plurality of uniformly surrounding filamentary members; the diameters of the filiform parts in the reinforcing layer are sequentially increased from inside to outside. The reinforcing layer formed by the filiform component has the advantages of effectively filling space, enhancing the rigidity of the outer layer strand, increasing the breaking force and the like, and simultaneously, the thickness of the reinforcing layer is sequentially increased from inside to outside through the change of the diameter of the filiform component, so that the effects of effectively filling and increasing the rigidity and the breaking force among the reinforcing layers are further enhanced.
In the embodiment of the disclosure, the reinforced cladding assembly 1 is provided with a reinforced core 11, and a first reinforced layer 12, a second reinforced layer 13 and a third reinforced layer 14 are clad around the reinforced core 11 from inside to outside; the layer thicknesses of the first reinforcing layer 12, the second reinforcing layer 13 and the third reinforcing layer 14 are sequentially increased, so that rotation can be reduced, load bearing is balanced, and yarn breakage and the like are not easily caused during stable operation, namely in the embodiment, in the structure shown in fig. 1, a preferable scheme is that three layers of reinforcing layers are arranged from inside to outside, and experimental effects prove that the layer number setting is the scheme with the least material and the best protection effect.
In the embodiment of the present disclosure, the diameter of the reinforced sheathing member 1 is 2 to 3 times the diameter of the reinforced core 11; the diameter of the wire-like member in the first reinforcing layer 12, the diameter of the wire-like member in the second reinforcing layer 13, and the diameter ratio of the wire-like member in the third reinforcing layer 14 are: 1.5-2-3, such as the optimal ratio of 1. The reinforced core 11 is a rope core composed of aramid fibers with excellent properties such as high strength, light weight and corrosion resistance, and has the functions of increasing the elasticity and toughness of the steel wire rope, storing oil and lubricating the steel wire rope and prolonging the service life of the steel wire rope. The structure belongs to a weak rotation steel wire rope structure, and has good adaptability to single-rope manned lifting operation.
In the embodiment of the present disclosure, the optical fiber assembly 3 is provided with an optical fiber 31 and an optical fiber paste column 32 surrounding the optical fiber 31; the protective layer 33, the adhesive layer 34 and the second reinforcing cladding tube 35 are arranged around the optical fiber paste column 32 from inside to outside in sequence. The optical fiber assembly 3 has a structure with a plurality of optical fibers 31 inside and an outer layer optical fiber protection device, and comprises, from inside to outside, an optical fiber 31, a fiber paste column 32, a protective layer 33, a viscous glue layer 34 and a second reinforced cladding tube 35.

The adhesive layer 34 is filled between the outer surface of the protective layer 33 and the inner surface of the second reinforcing cladding pipe 35, and since the adhesive layer 34 is a heat-curable adhesive with strong adhesion, it is a mixture formed by dissolving or dispersing polymers, organic compounds and mineral fillers in an organic solvent system, for example, a rubber heat-curable adhesive can be used; the protective layer 33 and the second reinforcing cladding pipe 35 can be firmly adhered together by the adhesive glue layer 34, so that relative movement between the second reinforcing cladding pipe 35 and the protective layer 33 is prevented, the phenomenon that the protective layer 33 and the optical fiber 31 are abraded due to relative movement is avoided, the overall flexibility and strength of the optical fiber assembly 3 are enhanced, the internal optical fiber 31 is further protected, and the reliability of optical fiber communication is guaranteed. The second reinforced cladding tube 35 is formed by winding a cold-rolled carbon steel strip, the steel strip is spirally and sequentially and tightly arranged during winding, and a wear-resistant layer made of a ceramic composite material with the thickness of 20-50 microns is arranged on the outer surface of the steel strip, so that the adhesive glue layer 34 and the protective layer 33 are prevented from being worn and damaged when the optical fiber assembly 3 and the second reinforced cladding tube 35 move relatively, internal communication optical fibers are protected, and the service life is prolonged.
In the embodiment of the present disclosure, a first reinforcing cladding tube 2 is further wrapped outside the optical fiber assembly 3, and the optical fiber assembly 3 is disposed in the first reinforcing cladding tube 2 in a shrinking and spiral manner. The first reinforced cladding pipe 2 is prepared by spirally and tightly winding a cold-rolled spring steel strip in sequence, is good in flexibility and strong in rigidity, can bear larger circumferential extrusion stress, and can still protect an internal structure from being damaged by extrusion of a plurality of outer strand steel wires under heavy load by virtue of an internal cavity when the steel strip is circumferentially pressed and axially elongated. A roughened alloy layer with high hardness (such as high manganese alloy (ZGMn 13Cr2 MoRe)) is arranged on the surface of the cold-rolled spring steel strip of the first reinforcing cladding pipe 2, which is in contact with the third reinforcing layer 14, so as to increase the friction force between the cold-rolled spring steel strip and the filiform part of the third reinforcing layer 14, and further improve the synchronous motion performance of the reinforcing cladding assembly 1 and the first reinforcing cladding pipe 2, and a wear-resistant layer made of ceramic nanocomposite with the thickness of 20-50 μm is arranged on the other surface of the cold-rolled spring steel strip of the first reinforcing cladding pipe 2, so as to improve the wear resistance of the optical fiber assembly 3 and the first reinforcing cladding pipe 2 to the second reinforcing cladding pipe 35 on the outer layer thereof when the optical fiber assembly 3 and the first reinforcing cladding pipe 2 move relatively, further enhance the protection of the adhesive layer 34 and the protection layer 33, and prolong the service life.
