Description

Technical Field

[0001] This utility model relates to the field of wire rope, and in particular to a wire rope resistant to extreme temperature changes. Background Technology

[0002] Steel wire rope is a helical bundle of multiple high-strength steel wires twisted according to certain rules. It is widely used in various material handling machinery for lifting, traction, tensioning, and load bearing. It mainly consists of steel wires, a core, and lubricating grease, and features high strength, light weight, stable operation, and resistance to sudden breakage, ensuring safe and reliable operation. The steel wires in steel wire ropes are made of various materials, including carbon steel and alloy steel, and are produced through cold drawing or cold rolling. The cross-sections come in various shapes, such as round or irregular (e.g., T-shaped, S-shaped, Z-shaped). Irregularly shaped cross-section steel wires are mainly used to produce sealed steel wire ropes, which have high tensile strength and toughness. The core provides support and is divided into a steel core and a fiber core (including natural fiber cores such as sisal, jute, and cotton, and synthetic fiber cores such as polyethylene and polypropylene filaments). The fiber core can also store a large amount of lubricating grease, which lubricates the steel wire rope and extends its service life. During the twisting process, wire ropes are sprayed with lubricating grease. This not only slows down wear on the wire surface but also isolates the wire surface from oxygen in the air, inhibiting oxidation and corrosion. Based on the material of the wire, surface condition, twisting method, and application, wire ropes can be classified into various types, such as carbon steel wire rope, stainless steel wire rope, phosphated coated wire rope, and galvanized wire rope. The resistance of wire ropes to extreme temperature changes is of great significance. In extreme high or low temperature environments, wire ropes can maintain stable mechanical and chemical properties, preventing breakage due to increased brittleness and reduced strength, ensuring operational safety. This weather resistance reduces equipment failures and downtime caused by temperature changes, improving production efficiency and equipment reliability. Simultaneously, it broadens the application areas of wire ropes, enabling them to function in more complex and extreme environments, providing a solid guarantee for the development of various industries. Therefore, a wire rope resistant to extreme temperature changes is needed. Utility Model Content

[0003] The main objective of this invention is to provide a steel wire rope that can withstand extreme temperature changes, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A steel wire rope resistant to extreme temperature changes includes a steel wire rope body, which is composed of a steel wire rope core and a steel wire structure. The steel wire rope core is composed of a core body and a high-temperature resistant core, which is located inside the core body. The steel wire structure is composed of a steel wire body, a high-temperature resistant coating, and a thermal insulation sheath. The thermal insulation sheath is fitted onto the steel wire body, the high-temperature resistant coating is applied to the steel wire body, and the steel wire rope body is filled with an anti-slip cushioning filler.

[0006] Preferably, the steel wire structure is of several types and is wound around the outside of the steel wire rope core.

[0007] Preferably, the high-temperature resistant fiber core on the wire rope core is an aramid fiber core, and the high-temperature resistant fiber core is fixedly connected to the rope core body.

[0008] Preferably, the high-temperature resistant coating on the steel wire structure is a ceramic coating.

[0009] Preferably, the thermal insulation sleeve on the steel wire structure is an EPDM rubber sleeve, and the thermal insulation sleeve is fixedly connected to the steel wire body.

[0010] Preferably, the anti-slip cushioning filler is made of thermoplastic polyurethane and is filled between the wire rope core and several wire structures.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By incorporating a high-temperature resistant core within the main body of the wire rope, which possesses a high melting point and heat resistance and remains stable under high-temperature conditions, the main body of the wire rope is protected from the effects of high temperatures. Furthermore, by adding an anti-slip buffer filler within the main body of the wire rope, the core and wire structure are effectively protected from slippage and cushioning. Finally, by applying a high-temperature resistant coating to the main body of the wire rope, the direct impact of high-temperature environments on the wire rope is effectively isolated, improving its high-temperature resistance. Finally, by installing a thermal insulation sleeve on the main body of the wire rope, the influence of external high and low temperature environments on the wire rope is effectively reduced, maintaining its operating temperature within a suitable range. Ultimately, this results in the main body of the wire rope exhibiting excellent resistance to extreme temperature changes. Attached Figure Description

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a steel wire rope resistant to extreme temperature changes includes a steel wire rope body 1, which is composed of a steel wire rope core 2 and steel wire structures 3. The steel wire rope core 2 is composed of a core body 8 and a high-temperature resistant core 9, with the high-temperature resistant core 9 located inside the core body 8. The steel wire structure 3 is composed of a steel wire body 5, a high-temperature resistant coating 6, and a thermal insulation sheath 7, which is fitted onto the steel wire body 5. The high-temperature resistant coating 6 is coated onto the steel wire body 5. The steel wire rope body 1 is filled with an anti-slip cushioning filler 4. Several steel wire structures 3 are present and wound around the outside of the steel wire rope core 2. In use, the steel wire rope core 2 is made of aramid fiber. The high-temperature resistant core 9 can protect the main body 1 of the wire rope from high temperature. The high-temperature resistant coating 6 made of ceramic coating on the wire structure 3 can effectively isolate the direct impact of the high temperature environment on the main body 5 of the wire rope and improve its high temperature resistance. The heat insulation sleeve 7 made of EPDM rubber on the wire structure 3 can effectively reduce the impact of external high temperature and low temperature environment on the main body 5 of the wire rope and keep its working temperature within a suitable range. Ultimately, the main body 1 of the wire rope has a good resistance to extreme temperature changes. The anti-slip buffer filler 4 made of thermoplastic polyurethane can play a good anti-slip and buffering role for the wire rope core 2 and the wire structure 3.

[0020] Furthermore, the high-temperature resistant core 9 on the wire rope core 2 is an aramid fiber core, and the high-temperature resistant core 9 is fixedly connected to the rope core body 8. By setting the high-temperature resistant core 9 inside the rope core body 8, the high-temperature resistant core 9 has a high melting point and heat resistance, and can remain stable in a high-temperature environment, thereby protecting the wire rope body 1 from the effects of high temperature.

[0021] Furthermore, the high-temperature resistant coating 6 on the steel wire structure 3 is a ceramic coating. By setting the high-temperature resistant coating 6 on the steel wire body 5, the direct influence of the high-temperature environment on the steel wire body 5 can be effectively isolated, thereby improving its high-temperature resistance.

[0022] Furthermore, the thermal insulation sleeve 7 on the steel wire structure 3 is a EPDM rubber sleeve, and the thermal insulation sleeve 7 is fixedly connected to the steel wire body 5. By setting the thermal insulation sleeve 7 on the steel wire body 5, the influence of external high temperature and low temperature environment on the steel wire body 5 can be effectively reduced, and its working temperature can be kept within a suitable range.

[0023] Furthermore, the anti-slip buffer filler 4 is made of thermoplastic polyurethane and is filled between the wire rope core 2 and several wire structures 3. By setting the anti-slip buffer filler 4 inside the wire rope body 1, the anti-slip buffer filler 4 can play a good anti-slip and buffering role for the wire rope core 2 and the wire structures 3.
