Description

Technical Field

[0001] The utility model relates to the technical field of steel wires, in particular to a rust-proof steel wire with a coated inner core. Background Art

[0002] Steel wire is one of the four major types of steel: plate, tube, profile and wire. It is a reprocessed product made from hot-rolled wire rods through cold drawing. According to the cross-sectional shape, there are mainly round, square, rectangular, triangular, elliptical, flat, trapezoidal, Z-shaped, etc. Steel wire, as a tension equipment, is widely used in industrial production and infrastructure construction.

[0003] For example, the patent document with application number 201821440161.2 discloses a waterproof and anti-aging steel wire rope, comprising several steel wires, a heat-conducting core and an inner core, wherein several steel wires are arranged on the outside of the inner core, an arc-shaped stainless steel plate is embedded on one side of the steel wire, a reinforcing tube is embedded on the inside of the inner core, a fixing column is arranged on the inside of the steel wire, and several anti-rust strips are embedded between the inner core and the several steel wires. The utility model discloses a waterproof and anti-aging steel wire rope, wherein the arc-shaped stainless steel plate is arranged on one side of the outer wall of the steel wire, which can protect the part of the steel wire exposed to the air and further improve its anti-rust and anti-aging effects. The design of the arc-shaped stainless steel plate being connected to the steel wire by several connecting columns can improve the tightness of the connection and enhance the stability during use. The heat-conducting core arranged at the center of the inner core can quickly conduct heat by heating, thereby evaporating the water vapor inside the steel wire rope and avoiding the accumulation of water vapor and causing internal rust.

[0004] For similar steel wire ropes, even if the water vapor inside the steel wire rope is evaporated by rapid heat conduction through heating, the steel wire rope will still react with oxygen when exposed to the air, causing rust on the surface of the steel wire rope. The steel wire rope is often subjected to friction during use, which causes wear and erosion between the outer skin and the inner cavity. Friction will cause wear on the inner and outer skin surfaces of the steel wire rope. If the outer skin is corroded by chemicals, it will also cause damage to the outer skin, thereby affecting the structural strength of the steel wire rope.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a coated inner core rust-proof steel wire is proposed. Utility Model Content

[0006] The utility model aims to provide a coated inner core rust-proof steel wire, which can evaporate the water vapor inside the steel wire rope by rapid heat conduction through heating, but still react with oxygen when the steel wire rope is exposed to the air, causing rust on the surface of the steel wire rope. The steel wire rope is often subjected to friction during use, resulting in wear and erosion between the outer skin and the inner cavity. Friction can cause wear on the inner and outer skin surfaces of the steel wire rope. If the outer skin is corroded by chemical substances, it will also cause damage to the outer skin, thereby affecting the structural strength of the steel wire rope.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coated inner core rust-proof steel wire, comprising a metal inner core, a reinforcement component, an inner layer tube, a middle layer tube and an outer layer tube, the outer surface of the metal inner core is provided with a galvanized layer, the reinforcement component is arranged on the outer side of the metal inner core, the reinforcement component is provided with six groups, the inner layer tube is sleeved on the outer surface of the six groups of the reinforcement components, the middle layer tube is arranged on the outer surface of the inner layer tube, and the outer layer tube is arranged on the outer surface of the middle layer tube.

The steel wire column is arranged on the outside of the metal inner core. The steel wire column is provided in three groups. The surfaces of the three groups of steel wire columns are all sleeved with a primary protective layer, and the outer surfaces of the three groups of steel wire columns are provided with a secondary protective layer, and the contact surface between the steel wire column and the primary protective layer is provided with a rust inhibitor.

[0010] Furthermore, the six groups of reinforcement components are arranged adjacent to each other in a hexagon, the outer surface of the metal inner core and the six groups of reinforcement components are in contact with each other, and the six groups of reinforcement components are spirally wound around the outer surface of the metal inner core.

[0012] Furthermore, the coating material of the anti-wear coating is polyurethane, and the coating material of the protective coating is epoxy resin.

[0013] Compared with the prior art, the utility model has the following beneficial effects: each steel wire is tightly wrapped by a primary protective tube made of polyvinyl chloride, which can effectively isolate the steel wire from direct contact with the humid environment, prevent the formation of an oxide layer, avoid the risk of rusting the steel wire rope, reduce friction between the steel wires, reduce wear, and the structure of the multi-layer tube can fully protect the metal core and the reinforcement components, improve their tensile strength and durability, and enable the steel wire to remain stable under high-intensity and high-frequency use. The specific contents are as follows:

The primary protective tube forms a protective film to prevent direct contact between oxygen and the surface of the steel wire column, effectively preventing the formation of an oxide layer, thereby reducing oxidation and rusting of the steel wire rope and extending its service life. The steel wire columns wrapped by the three groups of primary protective layers are arranged in a triangular structure, which increases the overall strength and stability and makes the steel wire rope more sturdy and durable.
