[0002] Steel wire rope is a spiral steel wire bundle twisted together according to certain rules by steel wires with required mechanical properties and geometric dimensions, and is composed of a core and strands. In material mechanical handling, the steel wire rope plays the role of lifting, traction, tensioning and load bearing, has high strength and light weight, and is stable and reliable in work, and is widely applied to various industries such as machinery, mining and metallurgy.

[0003] With the development of society and the vigorous rise of ocean industry, ocean engineering gradually enters people's field of vision. Ocean engineering refers to a new, reconstruction or expansion project with the purpose of developing, utilizing, protecting and restoring marine resources, and the engineering main body is located on the sea side of the coastline. It is generally considered that the main content of ocean engineering can be divided into two parts: resource development technology and equipment and facility technology, which specifically includes: reclamation, offshore dam engineering, artificial island, offshore and submarine material storage facilities, cross-sea bridge, submarine tunnel engineering, submarine pipeline and the like. As one of the indispensable tools for ocean engineering construction, the steel wire rope plays a vital role. However, the marine environment is humid and highly corrosive, and the service life of the steel wire rope is very short, and safety hazards are easily caused. Therefore, a corrosion-resistant steel wire rope for ocean engineering is proposed. SUMMARY

[0004] In view of the above problems, the utility model provides a corrosion-resistant steel wire rope for ocean engineering, which has high strength, corrosion resistance and long service life.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a corrosion-resistant steel wire rope for ocean engineering, comprising a composite core, a secondary outer layer wire strand and an outer layer wire strand, the secondary outer layer wire strand being arranged between the composite core and the outer layer wire strand. The composite core comprises synthetic fiber filaments, natural fiber filaments and fine steel wires, the natural fiber filaments spirally wrapping the synthetic fiber filaments, the fine steel wires being arranged outside between adjacent natural fiber filaments, and a fastening layer being arranged between the composite core and the secondary outer layer wire strand.

[0015] The marine engineering corrosion-resistant steel wire rope has the advantages that the marine engineering corrosion-resistant steel wire rope is provided with a sealing layer, a water-blocking layer, a rubber layer and a wear-resistant layer in sequence outside the outer layer wire strand, which plays a role of layer-by-layer protection on the internal structure of the steel wire rope, greatly improves the corrosion-resistant effect of the steel wire rope, and makes the steel wire rope more suitable for special marine and other humid environments. The water-blocking layer cooperates with the sealing layer to improve the water-blocking effect of the steel wire rope, prevents the internal structure of the steel wire rope from being corroded due to water and the phenomenon of local wire breakage of the steel wire rope, and greatly prolongs the service life of the steel wire rope. Further, the water-blocking layer adopts a combination of a water-blocking yarn layer and a carbon fiber cloth layer, which can improve the tensile strength of the water-blocking layer and strengthen the steel wire rope.

The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1 As shown, a corrosion-resistant steel wire rope for marine engineering includes a composite core, a secondary outer layer of steel wire strands 5, and an outer layer of steel wire strands 6. The secondary outer layer of steel wire strands 5 is disposed between the composite core and the outer layer of steel wire strands 6. The composite core includes synthetic fiber filaments 1, natural fiber filaments 2, and fine steel wires 3. The natural fiber filaments 2 are spirally twisted around the synthetic fiber filaments 1. The fine steel wires 3 are disposed on the outer side between adjacent natural fiber filaments 2. A fastening layer 4 is provided between the composite core and the outer layer of steel wire strands 6, i.e., the fine steel wires 3 are disposed between the natural fiber filaments 2 and the fastening layer 4. The outer steel wire strand 6 is sequentially provided with a sealing layer 7, a water-proof layer 8, a rubber layer 9, and a wear-resistant layer 10. The sealing layer 7 has several arc-shaped protrusions on the side near the outer steel wire strand 6, each protrusion being embedded in the outer periphery of the outer steel wire strand 6. The sealing layer 7 also has several second protrusions on the side near the water-proof layer 8. These second protrusions increase the frictional force between the sealing layer 7 and the water-proof layer 8, making the bond tighter and less prone to detachment. The water-proof layer 8 comprises n layers of water-blocking yarn, where n is greater than 2 and is a positive integer. A carbon fiber cloth layer is disposed between adjacent water-blocking yarn layers. Preferably, as shown in the embodiment, the water-proof layer 8 comprises 3 layers of water-blocking yarn and 2 layers of carbon fiber cloth, with the carbon fiber cloth layers respectively disposed between adjacent water-blocking yarn layers.

Combined with the waterproof layer 8, it effectively blocks moisture and prevents the internal structure from corroding in a humid environment.

[0024] The friction-resistant layer is a resin wear-resistant layer 10. The resin wear-resistant layer 10 is uniformly distributed with wear-resistant particles on the surface. The wear-resistant particles can be rubber particles or ceramic particles, which can improve the wear resistance of the steel wire rope and prevent the rubber layer 9, the water barrier layer 8 and the sealing layer 7 from being damaged in turn due to friction during use.

[0025] The fastening layer 4 is a carbon fiber mesh layer. By arranging the fastening layer 4, the stability and supportability of the composite core are improved, and the strength of the composite core is further improved.

[0026] The synthetic fiber 1 is a nylon fiber, and the natural fiber 2 is a sisal fiber. The synthetic fiber 1 is used in combination with the natural fiber 2, which can achieve good oil storage effect of the composite core and enhance the tensile strength of the composite core. Meanwhile, the fine steel wire 3 is arranged outside the natural fiber 2, which can further improve the supportability of the composite core. Preferably, the diameter of the fine steel wire 3 is 0.1-0.5 times the diameter of the natural fiber 2, as shown in the embodiment.

[0027] The composite core is filled with lubricating grease, which can fully lubricate the secondary outer layer steel wire strand 5 and the outer layer steel wire strand 6 and reduce the friction loss between the steel wires.
