Description

Technical Field

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

[0002] Steel wire rope is a helical bundle of steel wires that meet specific mechanical properties and geometric dimensions, twisted together according to certain rules. It mainly consists of steel wires, a core, and lubricant. It is first formed by twisting multiple layers of steel wires into strands, and then, with the core as the center, a certain number of strands are twisted into a helical rope. Steel wire rope has characteristics such as high strength, high elasticity, good toughness, light weight, wear resistance, smooth operation, resistance to sudden breakage, reliable operation, ability to withstand various loads and variable loads, and good corrosion resistance, enabling it to work normally in harsh environments with various harmful media. There are many types of steel wire rope. According to the twisting method, they can be divided into single-strand ropes, double-strand ropes, and compacted steel wire ropes; according to the surface treatment of the steel wires, they can be divided into bright steel wire ropes, galvanized steel wire ropes, and plastic-coated steel wire ropes; and according to the different core types, they can be divided into hemp core, asbestos core, and metal core steel wire ropes. In addition, wire ropes are also classified according to their uses, such as general-purpose wire ropes, elevator wire ropes, aviation wire ropes, oilfield wire ropes, aerial ropeway and cable car wire ropes, and lifting wire ropes. Wire ropes are mainly used for lifting, traction, tensioning, and load-bearing in material handling machinery, and are widely used in metallurgy, mining, oil and gas drilling, machinery, chemical industry, aerospace, and other fields. In existing technologies, wire ropes are easily corroded by the harsh environment. Corroded wire ropes have a significantly shortened service life and reduced mechanical strength, requiring frequent replacements, thus increasing operating costs. Furthermore, since wire ropes primarily provide lifting, traction, tensioning, and load-bearing functions, damage caused by corrosion increases the risk of accidents. Insufficient wire rope strength also increases the likelihood of accidents, potentially posing a serious threat to life. Utility Model Content

[0003] The main objective of this invention is to provide a high-strength, corrosion-resistant steel wire rope that 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 high-strength corrosion-resistant steel wire rope includes a main steel wire rope structure, which is composed of multiple outer steel wires. A reinforcing core is provided between the multiple outer steel wires. The reinforcing core consists of a metal sleeve, a rubber protective sleeve, a fiber core, and a metal reinforcing rope. The rubber protective sleeve is fitted onto the metal sleeve, and the fiber core and metal reinforcing rope are both disposed inside the metal sleeve. An anti-corrosion coating structure is provided on the outer steel wires, which consists of a chromium-plated corrosion-resistant layer, a zinc-plated corrosion-resistant layer, and an aluminum-plated corrosion-resistant layer.

[0006] Preferably, the multiple outer steel wires on the main structure of the steel wire rope are intertwined.

[0007] Preferably, the chromium-plated corrosion-resistant layer on the anti-corrosion coating structure is disposed on the outer steel wire body, the zinc-plated corrosion-resistant layer is disposed outside the chromium-plated corrosion-resistant layer, and the aluminum-plated corrosion-resistant layer is disposed outside the zinc-plated corrosion-resistant layer.

[0008] Preferably, the metal sleeve and rubber protective sleeve on the reinforcing core of the steel wire rope are fixedly connected.

[0009] Preferably, the reinforcing core of the steel wire rope has several fiber rope cores, and the several fiber rope cores are distributed in a ring inside the metal sleeve.

[0010] Preferably, the metal reinforcing rope on the steel wire rope reinforcing core is located between several fiber rope cores.

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

[0012] By applying an anti-corrosion coating structure consisting of a chromium-plated corrosion-resistant layer, a zinc-plated corrosion-resistant layer, and an aluminum-plated corrosion-resistant layer to the outer steel wire body, the corrosion resistance of the main steel wire rope structure can be improved, making it less susceptible to corrosion damage and thus reducing the probability of accidents. Furthermore, by incorporating a reinforcing core within the main steel wire rope structure, the strength of the main structure can be enhanced, making it less prone to breakage under heavy loads, ultimately further reducing the probability of accidents.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a high-strength corrosion-resistant steel wire rope includes a main steel wire rope structure 1, which is composed of multiple outer steel wire bodies 3. A reinforcing core 2 is provided between the multiple outer steel wire bodies 3. The reinforcing core 2 is composed of a metal sleeve 8, a rubber protective sleeve 9, a fiber rope core 10, and a metal reinforcing rope 11. The rubber protective sleeve 9 is fitted onto the metal sleeve 8, and the fiber rope core 10 and the metal reinforcing rope 11 are both located inside the metal sleeve 8. An anti-corrosion coating structure 4 is provided on the outer steel wire bodies 3, which is composed of a chromium-plated corrosion-resistant layer 5, a zinc-plated corrosion-resistant layer 6, and an aluminum-plated corrosion-resistant layer 7. The multiple outer steel wires 3 on the main rope structure 1 are intertwined. By setting an anti-corrosion coating structure 4 on the outer steel wires 3, consisting of a chromium-plated corrosion-resistant layer 5, a zinc-plated corrosion-resistant layer 6, and an aluminum-plated corrosion-resistant layer 7, the corrosion resistance of the main steel wire rope structure 1 can be improved, making the main steel wire rope structure 1 less susceptible to corrosion damage, thereby reducing the probability of accidents. By setting a steel wire rope reinforcing core 2 inside the main steel wire rope structure 1, the strength of the main steel wire rope structure 1 can be strengthened, making the main steel wire rope structure 1 less prone to breakage and damage under heavy loads, ultimately further reducing the probability of accidents.

[0020] Furthermore, the chromium-plated corrosion-resistant layer 5 on the anti-corrosion coating structure 4 is disposed on the outer steel wire body 3, the zinc-plated corrosion-resistant layer 6 is disposed on the outside of the chromium-plated corrosion-resistant layer 5, and the aluminum-plated corrosion-resistant layer 7 is disposed on the outside of the zinc-plated corrosion-resistant layer 6. The chromium-plated corrosion-resistant layer 5, the zinc-plated corrosion-resistant layer 6, and the aluminum-plated corrosion-resistant layer 7 on the anti-corrosion coating structure 4 have good corrosion resistance, thereby reducing the probability of the outer steel wire body 3 being corroded and broken.

[0021] Furthermore, the metal sleeve 8 and rubber protective sleeve 9 on the reinforcing core 2 of the wire rope are fixedly connected. There are several fiber rope cores 10 on the reinforcing core 2 of the wire rope, and the several fiber rope cores 10 are distributed in a ring inside the metal sleeve 8. The metal reinforcing rope 11 on the reinforcing core 2 of the wire rope is located between the several fiber rope cores 10. The metal sleeve 8, rubber protective sleeve 9, fiber rope cores 10 and metal reinforcing rope 11 cooperate with each other to strengthen the strength of the main structure 1 of the wire rope. At the same time, the presence of the rubber protective sleeve 9 can protect the outer wire rope body 3, thereby reducing the wear and tear on the outer wire rope body 3 during use.
