Description

Technical Field

[0001] This application relates to the field of splicable marine ropes and cables, specifically to a splicable marine rope and cable. Background Technology

[0002] Ropes and cables are key components in ship equipment, fishing, and port loading and unloading. Existing three-strand and eight-strand ropes and cables require high strength and wear resistance. With social development and the rise of the marine industry, the role of ship ropes and cables is becoming increasingly important, but they suffer from significant technical defects: 1. Short lifespan due to seawater corrosion. Seawater easily penetrates the rope's interior, and after drying, inorganic salt crystals deposit, damaging the structure and causing corrosion, reducing the rope's mechanical properties, shortening its service life, and increasing safety hazards. 2. Inconvenient connection operations. The rope's body is thick and heavy, making it difficult to fasten knots and hindering quick and free connection, limiting flexible application. 3. Insufficient performance and splicing capabilities. Poor toughness and low tensile strength make them unsuitable for high-load conditions; furthermore, the lack of an effective splicing mechanism limits the usable length, failing to meet the needs of marine operations.

[0003] Therefore, the development of durable and easy-to-connect ship cables has become an urgent need for the industry. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a splicable marine cable to solve the problems mentioned in the background art.

[0005] According to one aspect of this application, a splicable marine rope includes an inner core, inner strands, outer strands, a waterproof layer, an anti-corrosion layer, a first end plate, a second end plate, a first fixing sleeve, and a second fixing sleeve. The inner core is formed by twisting at least two steel wire ropes. Both ends of the inner core are fixedly connected to the first fixing sleeve and the second fixing sleeve, respectively. A first locking block is fixedly provided at the outer end of the first fixing sleeve, and a single connecting lug is fixedly provided on the outer end face of the first locking block. A first end plate is fixedly provided on the outer periphery of the first fixing sleeve and the first locking block. Multiple single connecting lugs are fixedly provided circumferentially on the outer end face of the first end plate around the outer periphery of the first locking block. A second locking block is fixedly provided at the outer end of the second fixing sleeve. The outer end face of the second card block is fixedly provided with double connecting ears. The second fixing sleeve and the outer periphery of the second card block are fixedly provided with a second end plate. On the outer end face of the second end plate, a plurality of double connecting ears are fixedly provided circumferentially along the outer periphery of the second card block. The setting position of the double connecting ears matches the setting position of the single connecting ears. The outer side of the inner core is wrapped with an inner layer of rope strands. The outer side of the inner layer of rope strands is wrapped with an outer layer of rope strands. The outer side of the outer layer of rope strands is wrapped with a waterproof layer. The outer side of the waterproof layer is wrapped with an anti-corrosion layer. The two ends of the inner layer of rope strands, the outer layer of rope strands, the waterproof layer and the anti-corrosion layer are respectively fixedly connected to the inner end face of the first end plate and the second end plate.

[0006] Preferably, the inner layer strands are composed of two closely arranged strands spirally wound around the outer side wall of the inner core, and the outer layer strands are composed of three closely arranged strands spirally wound around the outer side wall of the inner layer strands.

[0007] Preferably, the spiral direction of the inner strands is opposite to that of the outer strands.

[0008] Preferably, the inner core is formed by twisting three steel wire ropes.

[0009] Preferably, the waterproof layer is made of polypropylene and the anti-corrosion layer is made of polyisobutylene.

[0010] Preferably, when two ropes are connected, the single connecting lug on the first end plate of one rope end corresponds one-to-one with the double connecting lug on the second end plate of the other rope end and is fixedly connected by bolts.

[0011] The advantages of this application compared to existing technologies are as follows: This application provides a splicable marine rope, with the outer layer of the rope sequentially wrapped with a waterproof layer made of polypropylene and an anti-corrosion layer made of polyisobutylene. Polypropylene has excellent waterproof sealing properties, effectively preventing seawater from seeping into the rope's interior; polyisobutylene has excellent chemical corrosion resistance, resisting the erosion of the rope's substrate by inorganic salt crystals in seawater. Simultaneously, the tightly spirally wound structure of the inner and outer strands further reduces the gaps for seawater penetration, and, combined with the twisted steel wire rope structure of the inner core, prevents inorganic salt crystals from damaging the internal structure of the rope. The rope has a first end plate with a single connecting lug and a second end plate with double connecting lugs at both ends, with the single and double connecting lugs matched one-to-one. When two ropes need to be connected, there is no need for cumbersome tying knots; simply align the single connecting lug of one rope with the double connecting lug of the other rope, and quickly secure the connection with bolts.

[0017] To make the content of this application easier to understand, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to the accompanying drawings. Figure 1 In the context of direction, the terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0018] like Figures 1-4 As shown, a splicable marine cable includes an inner core 1, inner strands 2, outer strands 3, a waterproof layer 4, an anti-corrosion layer 5, a first end plate 6, a second end plate 7, a first fixing sleeve 8, and a second fixing sleeve 9. The inner core 1 is formed by twisting three steel wire ropes. The two ends of the inner core 1 are fixedly connected to the first fixing sleeve 8 and the second fixing sleeve 9, respectively. A locking block 10 is fixedly provided at the outer end of the first fixing sleeve 8. A single connecting lug 11 is fixedly provided on the outer end face of the locking block 10. The first end plate 6 is fixedly provided on the outer periphery of the first fixing sleeve 8 and the locking block 10. A circumferential fixing lug 11 is provided on the outer end face of the first end plate 6 located on the outer periphery of the locking block 10. Multiple single connecting ears 11 are provided. A second locking block 12 is fixedly provided at the outer end of the second fixing sleeve 9. A double connecting ear 13 is fixedly provided on the outer end face of the second locking block 12. A second end plate 7 is fixedly provided on the outer periphery of the second fixing sleeve 9 and the second locking block 12. Multiple double connecting ears 13 are fixedly provided on the outer end face of the second end plate 7 along the circumference of the second locking block 12. The setting position of the double connecting ears 13 matches the setting position of the single connecting ears 11. When two ropes are connected, the single connecting ears 11 on the first end plate 6 at the end of one rope correspond one-to-one with the double connecting ears 13 on the second end plate 7 at the end of the other rope and are fixedly connected by bolts.

[0019] The inner core 1 is wrapped with an inner layer of rope strands 2 on its outer side. The outer layer of rope strands 3 is wrapped with an outer layer of rope strands 3 on its outer side. The inner layer of rope strands 2 consists of two tightly arranged rope strands spirally and tightly wound along the outer side wall of the inner core 1. The outer layer of rope strands 3 consists of three tightly arranged rope strands spirally and tightly wound along the outer side wall of the inner layer of rope strands 2. The spiral direction of the inner layer of rope strands 2 is opposite to that of the outer layer of rope strands 3. The outer layer of rope strands 3 is wrapped with a waterproof layer 4. The outer layer of waterproof layer 4 is wrapped with an anti-corrosion layer 5. The waterproof layer 4 is made of polypropylene material, and the anti-corrosion layer 5 is made of polyisobutylene material. The two ends of the inner layer of rope strands 2, the outer layer of rope strands 3, the waterproof layer 4, and the anti-corrosion layer 5 are respectively fixedly connected to the inner end face of the first end plate 6 and the second end plate 7.

[0020] In the above design, the outer layer of the rope is sequentially wrapped with a waterproof layer 4 made of polypropylene and an anti-corrosion layer 5 made of polyisobutylene. Polypropylene has excellent waterproof sealing properties, effectively preventing seawater from penetrating into the rope's interior; polyisobutylene has excellent chemical corrosion resistance, resisting the erosion of the rope's substrate by inorganic salt crystals in seawater. Simultaneously, the tightly spirally wound structure of the inner strands 2 and outer strands 3 further reduces the gaps for seawater penetration. Combined with the steel wire rope twisting structure of the inner core 1, this prevents inorganic salt crystals from damaging the rope's internal structure. The synergistic effect of these designs significantly reduces seawater corrosion damage to the rope, substantially extending its service life in the marine environment.

[0021] The rope has a first end plate 6 with a single connecting ear 11 and a second end plate 7 with double connecting ears 13 at both ends, with the single connecting ear 11 and the double connecting ear 13 positioned identically. When two ropes need to be connected, there is no need for cumbersome knotting; simply align the single connecting ear 11 of one rope with the double connecting ear 13 of the other rope, and then quickly secure them with bolts. This design is suitable for the heavy nature of the ropes, simplifies the connection process, and enables free and quick connection of the ropes, meeting the flexibility requirements for rope connection in actual operations.

[0022] The inner core 1 is formed by twisting three steel wire ropes. The steel wire ropes themselves have high strength and high tensile strength, providing stable mechanical support for the cable. The inner strand 2 and the outer strand 3 are tightly spirally wound in opposite directions. The reverse spiral structure can counteract the torsional force when the cable is under stress, preventing the strands from loosening or deforming, while enhancing the overall toughness and structural stability of the cable. In addition, the inner strand 2, the outer strand 3, the waterproof layer 4, and the anti-corrosion layer 5 are all fixedly connected to end plates at both ends, further improving the overall structural strength of the cable and effectively solving the problems of poor toughness and low tensile strength of existing cables.

[0023] Based on the end plate connecting ear structure, not only can two ropes be conveniently connected, but also the overall usable length of the ropes can be flexibly extended by connecting multiple ropes in sequence (the second end plate 7 of the previous rope is connected to the first end plate 6 of the next rope) according to the actual operation requirements for rope length.

[0024] The above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them. Although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features, without departing from the spirit and scope defined by the claims of this application.
