Description

Technical Field

[0001] This utility model relates to the field of steel wire rope technology, and more specifically, to a high-strength plastic-coated steel wire rope. Background Technology

[0002] Steel wire rope is a high-strength, wear-resistant, and corrosion-resistant rope made of woven steel wires. It is widely used in construction, aviation, shipping, mining, transportation, and other fields. In modern industry, the application range of steel wire rope is becoming increasingly extensive, and its performance and quality are constantly being improved. The manufacturing and design of steel wire rope has become an important technical field, and its various performance indicators have become important standards for evaluating its quality.

[0003] As the service time of existing steel wire ropes increases, deformation and damage will occur. If users cannot detect the abnormality of the steel wire rope in time, it is easy for the steel wire rope to break under load, which will lead to safety accidents. Maintenance personnel need to inspect the entire surface of the steel wire rope, which will result in low efficiency.

[0004] A search revealed that Chinese patent CN219621491U discloses a steel wire rope. This device uses an adhesive layer to bond a protective netting to the outside of the rope core, protecting it from wear caused by the outer steel wire rope. A wear-resistant layer enhances the wear resistance of the outer fiber optic cable, preventing direct wear from the outer steel wire rope. During maintenance, operators illuminate one end of the steel wire rope with a flashlight. If the beam can be transmitted normally through the fiber optic cable to the other end, the wear is minimal. If the number of beams at the output end is less than the number at the input end, at least one outer strand has broken, requiring replacement of the steel wire rope. This method is convenient for observation and operation.

[0005] However, in actual use, this structure suffers from compression and wear between the steel wire and the rope groove, and fluctuations in the rope core diameter lead to fluctuations in the steel wire rope diameter, which in turn exacerbates the wear of the steel wire, significantly shortens the service life of the steel wire rope, and poses certain safety risks. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-strength plastic-coated steel wire rope to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-strength plastic-coated steel wire rope includes a central strand, on one side of which a plurality of inner steel wires are fixedly disposed, and the plurality of inner steel wires are twisted around the outside of the central strand, and a reinforcing mechanism is fixedly disposed on the surface of the inner steel wires;

[0009] The reinforcing mechanism includes a reinforcing cylinder fixedly disposed on the surface of the inner steel wire. A flexible filler is filled between the reinforcing cylinder and the inner steel wire. Multiple reinforcing steel wires are fixedly disposed on the surface of the reinforcing cylinder. The multiple reinforcing steel wires are all wound around the outside of the reinforcing cylinder. A fixing cylinder is fixedly disposed on one side of the reinforcing steel wire. A fiber core layer is filled between the fixing cylinder and the reinforcing cylinder. Multiple filling layers are fixedly disposed on the outside of the fixing cylinder. Inner strands are fixedly disposed inside the multiple filling layers. Multiple outer strands are twisted around the outer ring of each inner strand.

[0010] By adopting the above technical solution, in order to enhance the overall strength and fatigue resistance of the wire rope, and through multi-layer twisting to form a tight spiral structure, the overall strength and stability of the wire rope are further improved.

[0011] As a further description of the above technical solution: a protective mechanism is fixedly provided on the surface of the filling layer, the protective mechanism includes a wear-resistant coating layer fixedly provided on the surface of the filling layer, a reflective strip is fixedly provided on the surface of the wear-resistant coating layer, an anti-corrosion layer is fixedly provided on the outside of the reflective strip, and a waterproof layer is fixedly provided on the surface of the anti-corrosion layer.

[0012] By adopting the above technical solution, in order to enhance the overall anti-corrosion and waterproof effect and form a solid outer layer, the internal steel wire rope is effectively isolated, thereby extending the service life of the device.

[0013] As a further description of the above technical solution: an external wear-resistant layer is fixedly provided on one side of the waterproof layer, a magnetic particle layer is fixedly provided on the surface of the external wear-resistant layer, a fluorescent strip is fixedly provided on one side of the magnetic particle layer, the reinforcing cylinder and the fixing cylinder are both made of polyester fiber material, and the filling layer is made of plastic material.

[0014] By adopting the above technical solution, maintenance personnel can quickly inspect the surface of the wire rope, thereby improving work efficiency and enhancing safety.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By setting up a reinforcing mechanism, compared with the existing technology, a multi-layer structure design is adopted through the central strand, inner layer steel wire, and reinforcing steel wire. Each layer of rope strand is made of multiple steel wires twisted together to form a tight spiral structure, which improves the overall strength and stability of the wire rope. In addition, the flexible filler reduces gaps and enhances the overall flexibility of the wire rope, while also improving the sealing performance of the wire rope. Moreover, the fiber core layer can provide good support and has an oil storage function to work with the fixed cylinder to ensure reliable structural integrity. Furthermore, the outer ring of the inner layer strand is wrapped with multiple outer layer strands. The use of filler steel wire and alternating steel wire structure optimizes the stress distribution inside the rope strand, further improving the strength and fatigue resistance of the wire rope.

[0017] 2. By incorporating a protective mechanism, compared to existing technologies, the fluorescent strips facilitate easy monitoring of the wire rope's position even at night. Simultaneously, the magnetic particle layer attracts magnetic particles to the metal surface defects when scratches appear, creating a clear particle mark. This allows for the identification of cracks or other defects on the metal surface. Furthermore, when cracks are deep and have broken through the outer wear-resistant, waterproof, and anti-corrosion layers, the internal reflective strips are exposed, allowing for direct observation under external light. This facilitates timely detection and replacement by staff, ensuring the safety of the wire rope. Additionally, the anti-corrosion and waterproof layers effectively isolate the wire rope from the external environment, reducing wear and corrosion and extending the lifespan of the device.

A fixing cylinder 6 is fixedly mounted on one side of each reinforcing steel wire 5. A fiber core layer 7 is filled between the fixing cylinder 6 and the reinforcing cylinder 3. Multiple filling layers 8 are fixedly mounted on the outside of the fixing cylinder 6. Inner strands 9 are fixedly mounted inside each of the multiple filling layers 8. Multiple outer strands 10 are twisted around the outer ring of each inner strand 9. Through the central strand 1, the inner steel wire 2, and the reinforcing steel wires 5, a multi-layer structure design is adopted. Each layer of strands is made of multiple twisted steel wires, forming a tight spiral structure, which improves the steel... The overall strength and stability of the wire rope are improved, and the gaps are reduced by the flexible filler 4, which also enhances the overall flexibility of the wire rope and improves its sealing performance. The fiber core layer 7 inside the fixed cylinder 6 is made of several twisted fiber filaments. The fiber filaments are impregnated with grease, which can provide good support and oil storage function to ensure the reliable structure of the fixed cylinder 6. The filler layer 8 improves the wear resistance of the outer strands 10. In addition, multiple outer strands 10 are twisted around the outer ring of the inner strands 9. The inner and outer strands adopt a structure of filler wire and alternating steel wire to optimize the stress distribution inside the strands and further improve the strength and fatigue resistance of the wire rope.

[0027] Reference Figure 2-3As shown, a protective mechanism is fixedly provided on the surface of the filling layer 8. The protective mechanism includes a wear-resistant coating layer 11 fixedly provided on the surface of the filling layer 8, a reflective strip 12 fixedly provided on the surface of the wear-resistant coating layer 11, an anti-corrosion layer 13 fixedly provided on the outside of the reflective strip 12, and a waterproof layer 14 fixedly provided on the surface of the anti-corrosion layer 13. At the same time, the wear-resistant coating layer 11 and the outer wear-resistant layer 15 enhance the wear resistance effect, and the anti-corrosion layer 13 and the waterproof layer 14 enhance the long-term corrosion resistance and service life of this device.

[0028] Reference Figure 4-5 As shown, an external wear-resistant layer 15 is fixedly installed on one side of the waterproof layer 14, and a magnetic particle layer 16 is fixedly installed on the surface of the external wear-resistant layer 15. A fluorescent strip 17 is fixedly installed on one side of the magnetic particle layer 16. The reinforcing cylinder 3 and the fixing cylinder 6 are both made of polyester fiber, and the filling layer 8 is made of plastic. The fluorescent strip 17 makes it easy to check the position of the steel wire at night. At the same time, when scratches appear in the magnetic particle layer 16, the magnetic field will attract the magnetic particles to the defects on the metal surface, forming a clear particle mark, thereby judging whether there are cracks or defects on the metal surface. When the crack is deep and scratches through the external wear-resistant layer 15, the waterproof layer 14 and the anti-corrosion layer 13, the internal reflective strip 12 will be exposed. It can be directly observed by external light, so that the staff can find and replace it in time, ensuring the safety of the steel wire rope.

[0029] Working principle of this utility model:

[0030] This utility model relates to a high-strength plastic-coated steel wire rope. In use, the device employs a multi-layer structure design consisting of a central strand 1, inner layer steel wires 2, and reinforcing steel wires 5. Each layer of the rope is formed by twisting multiple steel wires, creating a tight spiral structure that improves the overall strength and stability of the steel wire rope. Furthermore, the flexible filler 4 reduces gaps and enhances the overall flexibility of the steel wire rope, while also improving its sealing performance. The fiber core layer 7 inside the fixed cylinder 6 is composed of several twisted fiber filaments impregnated with grease. These filaments provide good support and have an oil storage function, ensuring reliable structural integrity in conjunction with the fixed cylinder 6. The filler layer 8 improves the wear resistance of the outer layer strands 10. Moreover, multiple outer layer strands 10 are twisted around the outer ring of the inner layer strands 9. The use of filler steel wires and an alternating steel wire structure optimizes the stress distribution within the rope strands, further improving the strength and fatigue resistance of the steel wire rope.

[0031] The fluorescent strip 17 makes it easy to check the position of the steel wire even at night. At the same time, the magnetic particle layer 16 uses a magnetic field to attract magnetic particles to the defects on the metal surface when scratches occur, forming a clear particle mark, thereby determining whether there are cracks or other defects on the metal surface. When the crack is deep and scratches through the outer wear-resistant layer 15, waterproof layer 14 and anti-corrosion layer 13, the internal reflective strip 12 will be exposed. It can be directly observed by external light, so that the staff can find and replace it in time, ensuring the safety of the steel wire rope. At the same time, the wear-resistant coating layer 11 and the outer wear-resistant layer 15 enhance the wear resistance, and the anti-corrosion layer 13 and the waterproof layer 14 enhance the long-term corrosion resistance and service life of this device.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
