Description

Technical Field

[0001] The invention relates to the technical field of traction ropes, in particular to a large-tonnage impact-resistant hybrid traction rope. Background Art

[0002] The shipbuilding industry plays an important role in social and economic construction, especially large-tonnage ships. When a ship breaks down at sea, it needs to be rescued. During the maritime rescue, a rescue tugboat is needed to tow the ship. After the rescue tugboat personnel connect the towing rope to the ship to be rescued, the towing rope will sag and fall into the water under its own weight. The towing rope becomes heavier when it comes into contact with water, and it is easily corroded when immersed in seawater. In addition, the towing rope is easily broken and cracked under the action of tension and pulling during the towing process, and its impact resistance is poor. Summary of the invention

[0003] The purpose of the present invention is to provide a large-tonnage impact-resistant hybrid traction rope with good stability and corrosion resistance.

[0004] To achieve the above object, the technical solution provided by the present invention is: a large-tonnage impact-resistant hybrid traction rope, and the preparation method of the traction rope includes the following steps: The first step: twisting the prepared metal fiber wire to form a core wire; The second step: wind the carbon fiber mesh in a spiral shape on the surface of the core wire, and the winding direction of the nylon mesh is opposite to the winding direction of the core wire; Step 3: soak the core wire obtained in step 2 in a corrosion-resistant rubber solution to form a mixed layer; Step 4: Arrange the metal fibers and spirally wind them around the surface of the core wire coated with the mixed layer to form a center line; Step 5: Soak the core wire obtained in step 4 in a buffer layer solution to form a buffer layer; Step 6: Winding the nylon mesh cloth on the core wire completed in step 5 to form a reinforcement layer, the winding direction of the nylon mesh cloth is opposite to the winding direction of the metal fiber in step 4; Step 7: Soak the core wire obtained in step 6 in a corrosion-resistant solution to form a surface layer with a thickness of 1-3 mm; Step 8: Twist the core wires obtained in step 7 to form a traction rope, with the number of twisted core wires being 8-40.

[0005] The diameter of the metal fiber wire in the first step is 0.15-0.22 mm, the number of the metal fiber wires is 60-99, and they are twisted in a spiral shape to form a core wire.

[0006] The metal fiber wire diameter in the fourth step is 0.5-2 mm, and the number is 4-20.

[0007] The buffer layer solution in the fifth step is formed by mixing and dissolving polyurethane corrugated tape and natural rubber; the buffer layer thickness is 1-3 mm.

[0008] After adopting the above scheme, the surface of the core wire is coated with a carbon fiber mesh and then immersed in a mixed layer, which effectively increases the wear resistance and impact resistance of the core wire. After winding with a center wire, the tensile performance and impact resistance can be effectively increased. A buffer layer is used to protect the center wire. At the same time, the gap between the center wire and the mixed layer is filled to make the center wire and the mixed layer form a whole. Finally, a nylon mesh cloth is wrapped to form a reinforcement layer. The reinforcement layer is immersed in a corrosion-resistant solution to form a surface layer, so that the core wire has strong corrosion resistance and tensile performance. Finally, multiple core wires are twisted and mixed to form a traction rope. The traction rope has high tensile strength, good corrosion resistance, and strong impact resistance, and is particularly suitable for traction of large-tonnage ships.
