Description

Technical Field

[0001] This utility model relates to the field of stainless steel wire rope technology, and more specifically, to stainless steel wire rope that is not easily corroded or rusted. Background Technology

[0002] Stainless steel wire ropes are widely used in many fields. In the field of marine engineering, such as the construction of large offshore platforms, offshore drilling platforms, subsea drilling equipment, oil and gas pipelines and submarine cables, stainless steel wire ropes are in long-term contact with seawater and high salinity air. The chloride ions and other components in seawater are highly corrosive and can easily cause pitting corrosion at the defects in the steel inclusions. Ordinary steel wire ropes are also susceptible to corrosion. This has led to the demand for stainless steel wire ropes that are not easily corroded and rusted in order to improve the reliability and service life of equipment.

[0003] However, in actual use, stainless steel wire ropes are often found in coastal areas or on islands where the air has a high salt content, which is highly corrosive to metals. Moreover, traditional methods of rust prevention for steel wires are limited and cannot effectively isolate air and moisture, making the steel wires prone to rusting. This affects the overall strength and safety of the wire rope. Furthermore, the wire rope ends are not adequately sealed, allowing external moisture, dust, and other corrosive substances to easily penetrate from the ends, accelerating internal corrosion. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a stainless steel wire rope that is not easily corroded or rusted, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A stainless steel wire rope that is not easily corroded or rusted includes a wire rope body, wherein multiple inner layers of steel wires are fixedly arranged inside the wire rope body, and the surface of the inner layers of steel wires is provided with an anti-rust mechanism.

[0007] The rust prevention mechanism includes a reinforcing cylinder fixedly installed on one side of the inner steel wire. The surface of the inner steel wire is fixedly provided with a rust-preventive oil layer, which is made of nano zinc-based rust-preventive oil material. A flexible filler is fixedly installed between the inner steel wire and the reinforcing cylinder. A rope core is provided on one side of the reinforcing cylinder.

[0008] Multiple reinforcing steel wires are fixedly installed on one side of the reinforcing cylinder, a fixing cylinder is fixedly installed on one side of the reinforcing steel wires, a protective sleeve is fixedly installed on one side of the fixing cylinder, and a filling layer is provided between the fixing cylinder and the reinforcing steel wires.

[0009] The rope core is made of polyester fiber, the protective sleeve is made of polytetrafluoroethylene, and the filling layer is made of ethylene propylene rubber.

[0010] By adopting the above technical solutions: a nano-zinc-based anti-rust oil layer isolates corrosion, flexible filler strengthens rust prevention, polyester fiber rope core provides stable support and moisture absorption; ethylene propylene rubber filler layer is combined with reinforcing steel wire to improve strength and block external erosion; and polytetrafluoroethylene protective sleeve serves as the outer layer to resist chemical substances.

[0011] As a further description of the above technical solution: both ends of the wire rope body are provided with sealing mechanisms, and the sealing mechanism includes end rings fixedly disposed at both ends of the wire rope body, and the surface of the end rings is provided with threaded grooves.

[0012] A threaded ring is inserted into the inside of the threaded groove, and a sealing cap is fixedly installed on one side of the threaded ring.

[0013] By adopting the above technical solution, the sealing mechanism at both ends of the wire rope achieves effective sealing of the wire rope ends through the cooperation of the end ring, threaded ring and sealing cap.

[0014] As a further description of the above technical solution: a sealing layer is fixedly provided on one side of the sealing cover, and the sealing layer is made of silicone rubber.

[0015] The surface is provided with an anti-corrosion coating, which may be made of epoxy zinc-rich coating.

[0016] By adopting the above technical solution: the silicone rubber sealing layer on one side of the sealing cover, with its high elasticity and excellent sealing performance, tightly fills the tiny gaps between the wire rope end and the sealing effect, further enhancing the sealing effect; the epoxy zinc-rich anti-corrosion coating on the surface of the threaded ring resists various corrosive media with its excellent rust prevention performance, prevents the threaded ring from rusting, ensures the long-term operation of the sealing mechanism, and improves the overall protective performance and service life of the wire rope.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. By setting up an anti-rust mechanism, compared with existing technologies, the nano-zinc-based anti-rust oil layer on the surface of the inner steel wire forms a dense protective film, isolating air and moisture, and preventing the steel wire from rusting at the source; the reinforcing cylinder, combined with flexible filler, not only buffers external impacts and protects the anti-rust oil layer, but also fills gaps and reduces the risk of moisture intrusion. Moreover, the polyester fiber rope core provides stable support and can also absorb moisture, strengthen the synergy between the steel wire and the ethylene propylene rubber filler layer, enhance the overall strength, and effectively block the penetration of corrosive substances. The outermost polytetrafluoroethylene protective sleeve, with its extremely strong chemical stability, resists various chemical erosions, comprehensively improving the anti-corrosion performance and structural strength of the steel wire rope and extending its service life.

[0019] 2. By setting up a sealing mechanism, compared with existing technologies, the sealing mechanism at both ends effectively improves the overall protection performance through multiple protective designs. The threaded groove on the end ring provides a stable foundation for the installation of the sealing components. Together with the threaded ring and the sealing cap, it achieves a preliminary seal, isolating the wire rope end from the external environment. The silicone rubber sealing layer, with its good elasticity, tightly fits the gap, further blocking the intrusion of moisture and dust, forming a double protective barrier to prevent external corrosive substances from entering the wire rope from the end. The epoxy zinc-rich anti-corrosion coating on the surface of the threaded ring can resist various corrosive media, prevent the threaded ring from rusting, ensure the stability of its thread fit with the end ring, ensure the long-term reliable operation of the sealing structure, greatly reduce the risk of corrosion caused by exposure of the wire rope end, extend its service life, and ensure the safety and reliability of use.
