Description

Technical Field

[0001] This utility model belongs to the field of wire rope technology, specifically relating to a high-strength wire rope with a hollow structure. Background Technology

[0002] Steel wire rope is made of multiple high-strength steel wires twisted together. It can withstand huge tensile forces, with a tensile strength of 170MPa and above. Some special steel wire ropes can even have a tensile strength of over 3000MPa. It can ensure safety and reliability in lifting, hoisting and other operations and is not easy to break.

[0003] The steel wire has a specially treated surface and a tightly twisted structure, which can effectively resist wear and extend its service life in working environments with frequent friction and contact, such as mining and construction.

[0004] Some thicker wire ropes, due to their larger diameter and higher hardness, tend to have a smaller bending radius when bent. Furthermore, wire ropes subjected to bending compression and tension often experience slight deformation when subjected to high-intensity bending, making it difficult to restore their original shape and thus affecting the durability and lifespan of the wire rope.

[0005] Therefore, a high-strength steel wire rope with a hollow structure was designed to overcome the aforementioned technical defects. Utility Model Content

[0006] (1) Technical problems to be solved

[0007] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a high-strength steel wire rope with a hollow structure. This steel wire rope aims to solve the technical problem that steel wire ropes on the bending, compression and tension surfaces often suffer slight deformation when subjected to high-intensity bending, making it difficult to restore their original shape.

[0008] (2) Technical solution

[0009] To solve the above-mentioned technical problems, this utility model provides a high-strength steel wire rope with a hollow structure, including several wrapping layers and a filling layer. Multiple strands of steel wire are wound and connected inside the wrapping layers, and the multiple strands of steel wire are spirally wound and connected to each other. The wrapping layers are spirally wound and connected to the filling layer. The filling layer has a cylindrical hollow structure, and an elastic reset component is provided in the inner cavity of the filling layer.

[0010] Furthermore, the filler layer includes a wear-resistant layer and a rubber layer, with the rubber layer fixedly connected to the inner surface of the wear-resistant layer.

[0011] Furthermore, the elastic reset assembly includes a circular plate disposed in the inner cavity of the filling layer. Several limiting cylinders are movably connected to the side wall of the circular plate. Each limiting cylinder is movably connected to a movable rod. Several docking blocks are fixedly connected to the inner wall of the filling layer. The other end of each movable rod is movably connected to a docking block. Baffles are fixedly connected to the side walls of the limiting cylinders and the movable rods, and a spring is sleeved between the two baffles.

[0012] Furthermore, a spherical block is fixedly connected to the opposite end of the limiting cylinder and the movable rod, and spherical grooves are respectively opened on the side walls of the circular plate and the docking block, and the spherical block is adapted to the spherical groove.

[0013] Furthermore, the sidewalls of the filling layer are fitted with elastic metal wires.

[0014] Furthermore, the elastic metal wires are distributed in a spiral shape.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention, through the design of steel wire, filling layer and elastic reset components, makes the inside of the steel wire rope hollow. When the steel wire rope bends, it can increase the bending angle of the steel wire rope, making it more flexible. On the other hand, by setting multiple elastic reset components inside the steel wire rope, the steel wire can be reset after bending, reducing the deformation of the steel wire and extending its service life.

[0023] This specific embodiment is a high-strength steel wire rope with a hollow structure, and its structural schematic diagram is shown below. Figures 1-4 As shown, it includes several wrapping layers 1 and filling layers 3. Multiple strands of steel wire 2 are wound and connected inside the wrapping layer 1. The multiple strands of steel wire 2 are spirally wound and connected to each other. The wrapping layer 1 is spirally wound and connected to the filling layer 3. The filling layer 3 is a cylindrical hollow structure. An elastic reset component is provided in the inner cavity of the filling layer 3.

[0024] like Figure 2 As shown, the filler layer 3 includes a wear-resistant layer 5 and a rubber layer 6, with the rubber layer 6 fixedly connected to the inner surface of the wear-resistant layer 5.

[0025] Specifically, the wear-resistant layer 5 uses a metal coating, such as zinc or aluminum plating. Zinc and aluminum, among other metals, have good corrosion resistance and a certain degree of wear resistance. The zinc plating layer forms a protective film on the surface of the wire rope, effectively preventing it from being corroded by the external environment, while also increasing the surface hardness and reducing wear. The aluminum plating layer has higher high-temperature resistance and good oxidation resistance, protecting the wire rope in harsh working environments. Furthermore, the rubber layer 6 protects the internal elastic reset component and provides good rebound, facilitating the reset of the wire rope.

[0026] like Figure 3 and Figure 4 As shown, the elastic reset assembly includes a circular plate 7 disposed in the inner cavity of the filling layer 3. Several limiting cylinders 8 are movably connected to the side wall of the circular plate 7. Movable rods 9 are movably connected inside each limiting cylinder 8. Several docking blocks 13 are fixedly connected to the inner wall of the filling layer 3. The other end of the movable rod 9 is movably connected to the docking block 13. Baffles 10 are fixedly connected to the side walls of the limiting cylinders 8 and the movable rods 9 respectively. A spring 11 is sleeved between the two baffles 10.

[0027] When the wire rope bends, the movable rod 9 on the bent side moves into the limiting cylinder 8, while the spring 11 is compressed. The movable rod 9 on the outer side of the bend is also slightly moved into the limiting cylinder 8 due to the pressure. When the wire rope changes from a bent state to a horizontal or vertical state, the multiple springs 11 in multiple directions are used to reset the multiple strands of wire 2, so that they are in their initial state, thus preventing the wire rope from deforming or loosening.

[0028] like Figure 4 As shown, spherical blocks 12 are fixedly connected to the ends of the limiting cylinder 8 and the movable rod 9, which are far apart from each other. Spherical grooves 14 are respectively opened on the side walls of the circular plate 7 and the connecting block 13, and the spherical blocks 12 are adapted to the spherical grooves 14. By using a ball joint at both ends of the limiting cylinder 8 and the movable rod 9, the wire rope has high flexibility when bending, and the elastic reset component can swing flexibly within the filling layer 3, further improving its performance.

[0029] like Figure 2As shown, the sidewall of the filling layer 3 is fitted with elastic metal wires 4. The elastic metal wires 4 are spirally distributed. The elastic metal wires 4 can maintain a certain elasticity. When the wire rope bends, the elastic metal wires 4 begin to bear force, and in the initial state, the elastic metal wires 4 can keep the wire rope in a horizontal or vertical state, playing an auxiliary role in resetting.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
