Description

Technical Field

[0001] This utility model relates to the field of coal mine equipment technology, specifically to a steel wire rope assembly for coal mines. Background Technology

[0002] Wire rope is a flexible rope made of multiple twisted steel wires. It is widely used in various fields such as lifting, hoisting, transportation, mining, construction, and mechanical transmission. In the coal mining operation system, wire rope is a core component, and its performance is directly related to the safety and efficiency of production.

[0003] Existing steel wire ropes in some coal mines have revealed many drawbacks. On the one hand, their load-bearing capacity is insufficient, making it difficult to cope with the increasing demand for high-intensity and high-load operations in coal mines. They are prone to breakage accidents due to overload. Because steel wire is relatively heavy, the coal transport channel is divided into multiple sections to overcome the weight of the steel wire when transporting coal in the mine. On the other hand, their service life is relatively short. The harsh environment in coal mines, such as strong acid and alkali corrosion, flammability, and continuous mechanical friction, accelerates the wear and corrosion of steel wire ropes. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, this utility model provides a lightweight and high-strength steel wire rope assembly for coal mines with good flame retardant and corrosion resistance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel wire rope assembly for coal mines, comprising a steel wire rope body, wherein the steel wire rope body includes an outer ring located inside the steel wire rope body, a rope core is disposed inside the outer ring, a flame-retardant layer is disposed on the outer surface of the outer ring, a pressure-resistant layer is disposed on the surface of the flame-retardant layer, a wear-resistant layer is disposed on the outer surface of the pressure-resistant layer, and anti-slip stripes are disposed on the surface of the wear-resistant layer.

[0006] The rope core includes several outer filaments, which are arranged inside the outer ring. A central filament is spirally twisted inside the several outer filaments. A protective layer is provided on the outer surface of the central filament. An anti-corrosion layer is provided on the surface of each of the several outer filaments. A wear-resistant layer is provided on the surface of the anti-corrosion layer.

[0007] Furthermore, the outer ring is made of basalt material, and the central wire is a composite wire composed of several polymer fibers and galvanized steel wire.

[0008] Furthermore, the polymer fiber is made of aramid fiber.

[0009] Furthermore, the protective layer comprises a woven layer made of basalt fiber, aramid flame-retardant fiber filaments and flame-retardant and water-resistant yarn, and a halogen-free flame-retardant and anti-corrosion coating applied to the outer surface of the woven layer.

[0010] Furthermore, the anti-corrosion layer includes a flame-retardant and water-blocking rubber layer disposed around the outer periphery of the outer filaments and a halogen-free flame-retardant and anti-corrosion coating disposed outside the flame-retardant and water-blocking rubber layer. A filler is disposed between several of the outer filaments and the central filament, and the filler is a natural rubber material.

[0011] Furthermore, the wear-resistant layer is woven from a composite material of basalt fiber and wear-resistant resin, the compressive strength layer is woven from a composite material of basalt fiber and epoxy resin, and the flame-retardant layer is made of flame-retardant rubber material.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This steel wire rope assembly for coal mines significantly reduces the weight of the steel wire rope by incorporating a rope core and using basalt materials, thereby improving transportation efficiency. Furthermore, the addition of a flame-retardant layer effectively enhances the fire resistance of the steel wire rope, meeting the stringent flame-retardant requirements of underground coal mines.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 A steel wire rope assembly for coal mines in this embodiment includes a steel wire rope body 1. The steel wire rope body 1 includes an outer ring 101 located inside the steel wire rope body 1. A rope core 102 is disposed inside the outer ring 101. A flame-retardant layer 103 is disposed on the outer surface of the outer ring 101. A compression-resistant layer 104 is disposed on the surface of the flame-retardant layer 103. An anti-wear layer 105 is disposed on the outer surface of the compression-resistant layer 104. Anti-slip stripes 106 are disposed on the surface of the anti-wear layer 105.

[0021] The rope core 102 includes a plurality of outer filaments 1021, which are disposed inside the outer ring 101. A center filament 1022 is spirally twisted inside the plurality of outer filaments 1021. A protective layer 1023 is provided on the outer surface of the center filament 1022. An anti-corrosion layer 1024 is provided on the surface of each of the plurality of outer filaments 1021. A wear-resistant layer 1025 is provided on the surface of the anti-corrosion layer 1024.

[0022] like Figure 1 As shown, basalt material is set in the outer ring 101, and the central wire 1022 is made of a composite wire composed of polymer fiber and galvanized steel wire twisted together. This structural design makes full use of the high strength and lightweight characteristics of basalt material, as well as the composite advantages of polymer fiber and galvanized steel wire. The polymer fiber is aramid fiber, which has high strength and light weight, and can provide good flexibility and impact resistance. At the same time, it reduces the overall weight of the wire rope, which not only ensures the load-bearing capacity of the wire rope, but also effectively reduces its own weight. In addition, the basalt material in the outer ring 101 also gives the wire rope excellent wear resistance and corrosion resistance, enabling it to operate stably for a long time in the harsh environment of underground coal mines.

[0023] like Figure 3 As shown, a protective layer 1023, woven from basalt fiber, aramid flame-retardant fiber filaments, and flame-retardant and water-resistant yarn, is also provided on the outer surface of the central wire 1022. A halogen-free flame-retardant and anti-corrosion coating is then applied to the outside of this layer. This halogen-free flame-retardant and anti-corrosion coating not only has good anti-corrosion performance and can further protect the woven layer, but also uses a halogen-free formula, which will not release halogen-containing toxic gases in the event of a fire, meeting the environmental protection and safety requirements of coal mines. This protective layer 1023 not only provides the wire rope with additional flame-retardant properties, but also enhances its corrosion resistance and waterproof performance. In the underground environment of coal mines, this protective layer 1023 can effectively resist the common risks of moisture, acid and alkali corrosion, and fire in mines, ensuring the safety and reliability of the wire rope under complex working conditions.

[0024] like Figure 3As shown, an anti-corrosion layer 1024 is also provided on the surface of the outer wire 1021. The anti-corrosion layer 1024 is composed of a flame-retardant and water-blocking rubber layer and a halogen-free flame-retardant and anti-corrosion coating. This double-layer anti-corrosion design further improves the corrosion resistance of the wire rope, enabling it to resist the acid and alkali corrosion and humid environment commonly found in mines. At the same time, the flame-retardant and water-blocking rubber layer also has good elasticity and wear resistance, which can effectively reduce the wear of the wire rope during operation and extend its service life.

[0025] like Figure 3 As shown, natural rubber is filled between the outer filament 1021 and the central filament 1022 of the rope core 102. This filler can not only fill the gaps inside the rope core 102 and improve the overall structural stability of the wire rope, but also buffer external impacts to a certain extent and reduce the damage to the wire rope during operation. In addition, the elastic properties of natural rubber can further improve the flexibility of the wire rope, making it more adaptable to complex mining conditions.

[0026] like Figure 2 As shown, both the wear-resistant layer 105 and the wear-resistant layer 1025 are woven from a composite material of basalt fiber and wear-resistant resin. This composite material combines the high strength of basalt fiber with the excellent wear resistance of wear-resistant resin, which can significantly improve the wear resistance of the wire rope. The compression-resistant layer 104 is woven from a composite material of basalt fiber and epoxy resin. This composite material has excellent mechanical properties and dimensional stability. The flame-retardant layer 103 is made of flame-retardant rubber material. This material has good flame-retardant properties and can effectively prevent the spread of fire.

[0027] like Figure 1 As shown, by setting anti-slip stripes 106, the wire rope body 11 has an anti-slip effect.

[0028] It should be noted that the wire rope body 1 adopts a straight strand braiding method. The straight strand braiding method means that the strands of the wire rope remain in a straight line during the braiding process, without the traditional spiral twisting. This braiding method makes the structure of the wire rope more compact and the contact between the strands closer, thereby improving the overall strength and stability of the wire rope. Due to its high strength and wear resistance, the straight strand braided wire rope is suitable for the coal mining industry.

[0029] When implementing this procedure, please follow these steps:

[0030] 1) By using a composite wire of polymer fiber and galvanized steel wire in the core 102, and by applying lightweight and high-strength materials such as basalt fiber in the protective layer 1023 and the anti-corrosion layer 1024, the weight of the wire rope is effectively reduced. This makes the wire rope lighter and easier to transport in mines, reducing the extra burden caused by its own weight and thus improving transportation efficiency;

[0031] 2) Then, the flame-retardant layer 103 of the wire rope is made of flame-retardant rubber material, which has excellent fire resistance and can effectively prevent the spread of fire. In addition, the aramid flame-retardant fiber filaments and flame-retardant and water-resistant yarn in the protective layer 1023 further enhance the flame-retardant effect of the wire rope. This design meets the strict requirements for flame-retardant performance in underground coal mines and improves the safety of the mine.

[0032] 3) The compressive layer 104 of the steel wire rope is woven from basalt fiber and epoxy resin composite material. This material has the characteristics of high modulus and high strength, which can effectively withstand the large pressure on the steel wire rope in coal mining operations. This allows the steel wire rope to maintain good performance and stability under harsh working conditions.

[0033] 4) Furthermore, the wear-resistant layer 1025 and the wear-resistant layer 105 of the wire rope are woven from basalt fiber and wear-resistant resin composite material. This material has excellent wear resistance and can effectively resist the wear of hard objects such as coal blocks in the mine. This extends the service life of the wire rope and reduces the frequency of maintenance and replacement.

[0034] 5) Finally, the anti-corrosion layer 1024 of the wire rope includes a flame-retardant and water-resistant rubber layer and a halogen-free flame-retardant and anti-corrosion coating. These materials have good chemical corrosion resistance and can effectively resist the erosion of corrosive substances such as strong acids and alkalis in the mine. This improves the durability of the wire rope and enables it to maintain good performance in the harsh mining environment.

[0035] In summary, this steel wire rope assembly for coal mines, by incorporating a core 102 and utilizing basalt material, significantly reduces the weight of the steel wire rope, thereby improving transportation efficiency. Furthermore, the addition of a flame-retardant layer 103 effectively enhances the fire resistance of the steel wire rope, meeting the stringent flame-retardant requirements of underground coal mines. The inclusion of a compressive strength layer 104 and a wear-resistant layer 1025 increases the compressive strength of the device, effectively withstanding the substantial pressure exerted on the steel wire rope during coal mine operations. Finally, the addition of an anti-corrosion layer 1024 improves the device's corrosion resistance, thereby enhancing the steel wire rope's resistance to strong acids and alkalis.
