Description

Technical Field

[0001] This utility model relates to the field of fishing equipment technology, specifically to a steel wire rope for fishing and a composite steel wire rope. Background Technology

[0002] Steel wire rope is a core load-bearing component in fishing operations, widely used in trawls, purse seines, and net-hauling machines. It must withstand complex conditions such as seawater corrosion and load impacts over long periods. Traditional fishing steel wire ropes are mostly made of ordinary carbon steel wire with galvanization. However, because chloride ions in seawater can easily penetrate the galvanized layer, the steel wire undergoes electrochemical corrosion, resulting in rust and wire breakage, thus limiting its service life to 6-12 months. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a steel wire rope for fishery and a composite steel wire rope, which solves the problem of short service life of existing steel wire ropes used in fishery operations.

[0004] The technical solution adopted in this utility model is as follows: A steel wire rope for fishing, comprising a steel wire rope core, and further comprising: A waterproof layer is installed on the outside of the wire rope core; The rope consists of several strands that are evenly twisted around the outside of the waterproof layer.

[0005] The waterproof layer consists of at least two layers of plastic film.

[0006] The outer side of the rope is coated with a wear-resistant material.

[0007] The rope is made of polypropylene, nylon, or a mixture of polyester fiber and polypropylene filament.

[0008] The rope consists of 32 strands. A composite steel wire rope is formed by twisting at least two of the above-mentioned fishery steel wire ropes together.

[0009] The beneficial effects of this utility model are: The waterproof layer and the outer rope work together to effectively prevent seawater from contacting the wire rope core. The multiple rope strands can disperse frictional losses, while the outer rope also plays an auxiliary role in bearing force, increasing the overall load limit and thus effectively improving the service life of the wire rope.

[0011] Figure 2 This is a cross-sectional schematic diagram of the present invention.

[0012] 1. Steel wire rope core; 2. Waterproof layer; 3. Rope body; 4. Wear-resistant coating. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments: In the embodiments, such as Figure 1 , Figure 2 As shown, a steel wire rope for fishing includes a steel wire rope core 1, and further includes: Waterproof layer 2 is installed on the outside of the wire rope core 1; The rope 3 has several strands that are evenly twisted around the outside of the waterproof layer 2.

[0014] The wire rope core 1 is made of stainless steel, galvanized steel, or alloy steel. The waterproof layer 2 and the outer rope body 3 work together to effectively prevent seawater from contacting the wire rope core 1. The multi-strand rope body 3 can disperse frictional loss, and the outer rope body 3 also plays an auxiliary role in bearing force, increasing the overall load limit, thereby effectively improving the service life of the wire rope.

[0015] In the embodiments, such as Figure 1 , Figure 2 As shown, the waterproof layer 2 consists of at least two layers of plastic film. Two or more layers of plastic film can effectively improve the barrier effect against seawater.

[0016] In the embodiments, such as Figure 2 As shown, the outer side of the rope 3 is provided with a wear-resistant coating 4. The wear-resistant coating 4 is a layer of grease or machine oil, which can ensure the wear resistance of the rope 3, thereby ensuring the service life of the rope 3.

[0017] In this embodiment, the rope 3 is made of polypropylene, nylon, or a mixture of polyester fiber and polypropylene filament. Polypropylene rope is lightweight and durable, with good strength, abrasion resistance, and corrosion resistance, while nylon rope has good abrasion resistance and tensile strength, is not prone to aging or cracking, and has good elasticity; the polyester fiber and polypropylene filament mixed rope has good abrasion resistance and high strength, and is lighter than nylon rope. Different materials can be selected for the rope according to the needs of the operation.

[0018] In this embodiment, the number of ropes 3 is 32 strands. Multiple strands of rope 3 can effectively improve tensile strength and fracture resistance, while also preventing premature wear or breakage of localized ropes due to concentrated stress, thus extending the service life of the wire rope.

[0019] In this embodiment, a composite steel wire rope is formed by twisting at least two of the aforementioned fishing steel wire ropes together. Twisting multiple fishing steel wire ropes together to form a composite steel wire rope can distribute stress, improve overall tensile strength, increase overall toughness, reduce the risk of breakage, and enhance operational reliability.

[0020] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
