Description

Technical Field

[0001] This utility model relates to the field of high-temperature pressure-resistant spring steel wire rope technology, and in particular to a high-temperature pressure-resistant spring steel wire rope. Background Technology

[0002] Existing high-temperature compressive spring steel wire ropes, by incorporating heat-resistant and corrosion-resistant coatings, prevent corrosion damage from contact with rainwater during use. However, because the wire rope is composed of multiple strands of steel wire, friction between them during use can cause wear, making the worn areas susceptible to rust upon contact with rainwater. For example, Chinese patent disclosure "A High-Temperature Compressive Spring Steel Wire Rope" (application number: CN202322720344.7) uses heat-resistant and corrosion-resistant coatings to prevent corrosion damage from contact with rainwater, but its application is limited by the fact that the multiple strands of steel wire are prone to wear due to friction. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a high-temperature pressure-resistant spring steel wire rope. By providing an inner wear-resistant coating and an outer wear-resistant coating on the surfaces of the inner and outer rope bodies, wear at the contact points between the inner and outer steel wire rope bodies due to friction during use is prevented, thus preventing rainwater from contacting the rope surface and causing corrosion, which would affect the service life of the steel wire rope.

[0004] This utility model also provides a high-temperature pressure-resistant spring steel wire rope, comprising: an inner rope body, and a plurality of outer rope bodies arranged on the outer side of the inner rope body. The outer rope bodies are spiral structures and are evenly distributed in a ring around the inner rope body. Both the inner and outer rope bodies are provided with a pressure-resistant layer. A high-temperature resistant layer is provided on the pressure-resistant layer. A corrosion-resistant layer is provided on the high-temperature resistant layer. An inner wear-resistant coating is provided on the corrosion-resistant layer. An outer wear-resistant coating is provided on the outer side of the inner wear-resistant coating. Through the above structure, it is easy to prevent wear at the contact point between the inner and outer steel wire rope bodies due to friction during use, so as to prevent rainwater from contacting the rope surface and causing corrosion, thus affecting the service life of the steel wire rope.

[0005] According to the present invention, a high-temperature pressure-resistant spring steel wire rope is provided, wherein the pressure-resistant layer is made of polytetrafluoroethylene. The above structure facilitates pressure resistance and prevents the steel wire rope from being deformed by pressure, thus affecting its use.

[0006] According to the present invention, a high-temperature resistant spring steel wire rope is provided, wherein the high-temperature resistant layer is an inorganic coating, such as an inorganic silicate coating. The above structure facilitates the reduction of the impact of high temperature on the steel wire rope, thereby facilitating its use.

[0007] According to the present invention, a high-temperature pressure-resistant spring steel wire rope is provided, wherein the corrosion-resistant layer is a polyurethane coating composed of polyurethane material. Through the above structure, the steel wire rope is prevented from being corroded, and its service life is extended.

[0008] According to the present invention, the outer wear-resistant coating and the inner wear-resistant coating are made of the same material, namely metal plating, such as zinc, chromium, and nickel. The above structure facilitates wear resistance and prevents wear at the contact point due to friction.

[0009] According to the present invention, a high-temperature pressure-resistant spring steel wire rope is provided, wherein both the inner rope body and the outer rope body are located within the outer wear-resistant coating. This structure facilitates the prevention of other objects from causing wear on the surface.

[0010] Beneficial effects:

[0011] Compared with existing technologies, this high-temperature pressure-resistant spring steel wire rope has an inner wear-resistant coating and an outer wear-resistant coating on the surfaces of the inner and outer rope bodies. This prevents wear at the contact points between the inner and outer steel wire rope bodies due to friction during use, and prevents rainwater from contacting the rope surface, which would cause corrosion and affect the service life of the steel wire rope.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Reference Figure 1-4 This utility model discloses a high-temperature compressive strength spring steel wire rope, comprising: an inner rope body 1, and several outer rope bodies 2 arranged on the outer side of the inner rope body 1. The outer rope bodies 2 have a spiral structure for better strength and are evenly distributed in a ring around the inner rope body 1 to determine the position of the outer rope bodies 2. Both the inner rope body 1 and the outer rope bodies 2 are provided with a compressive strength layer 4 for compressive strength. The compressive strength layer 4 is made of polytetrafluoroethylene (PTFE). The material of the compressive strength layer 4 is determined for compressive strength. A high-temperature resistant layer 5 is provided on the compressive strength layer 4 for high-temperature resistance. A corrosion-resistant layer 6 is provided on the high-temperature resistant layer 5 for corrosion resistance. The corrosion-resistant layer 6 is a polyurethane coating composed of polyurethane material. The material of the corrosion-resistant layer 6 is determined to facilitate corrosion resistance and prevent the wire rope from being corroded, thus affecting its use. An inner wear-resistant coating 7 is provided on the corrosion-resistant layer 6, and an outer wear-resistant coating 3 is provided on the outside of the inner wear-resistant coating 7. The outer wear-resistant coating 3 is made of the same material as the inner wear-resistant coating 7, which is a metal plating, such as zinc, chromium, and nickel, to facilitate wear resistance, reduce wear at the contact points, and thus extend the service life. The inner rope body 1 and the outer rope body 2 are both located within the outer wear-resistant coating 3 to prevent wear caused by contact with other objects.

[0021] Working principle: During use, the design of the high-temperature resistant layer 5 and the corrosion-resistant layer 6 helps to prevent the impact of high temperature and rainwater on the wire rope. The design of the pressure-resistant layer 4 helps to prevent the wire rope from being crushed and affecting its use. The design of the outer wear-resistant coating 3 and the inner wear-resistant coating 7 can prevent the high-temperature resistant layer 5, the corrosion-resistant layer 6, and the pressure-resistant layer 4 from being worn due to friction between multiple strands of wire rope. At the same time, it can prevent friction with other objects, so that the worn parts come into contact with rainwater and rust occurs.
