Description

Technical Field

[0001] The present application relates to the technical field of steel wire ropes, and in particular to a zinc-aluminum alloy steel wire rope. Background Art

[0002] Steel wire rope is a helical bundle of steel wires twisted together according to certain rules, with steel wires that meet the requirements for mechanical properties and geometric dimensions. Steel wire rope is first twisted into strands from multiple layers of steel wire, and then a certain number of strands are twisted into a helical rope around the rope core. In material handling machinery, it is used for lifting, pulling, tensioning, and carrying. Steel wire materials include carbon steel, alloy steel, and zinc-aluminum alloy. Among them, zinc-aluminum alloy has mechanical properties close to or even exceeding those of lead brass, is easy to process and form, and has no cracks, pores, or pinholes. Torque tests can meet most industry standards.

[0003] At present, in order to improve the bearing capacity of the zinc-aluminum alloy steel wire rope used in the field of slope protection, the diameter of the steel wire rope is often increased. However, after the diameter of the steel wire rope is increased, its bending radius is reduced, and the bending performance is greatly reduced, thereby reducing the service life of the steel wire rope. Therefore, the present application proposes a zinc-aluminum alloy steel wire rope. Summary of the Invention

[0004] The purpose of this application is to solve the problems in the above-mentioned background technology, and this application provides a zinc-aluminum alloy steel wire rope.

[0005] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0006] A zinc-aluminum alloy steel wire rope, comprising:

[0007] The composite core strand includes a first rubber sleeve, wherein a plurality of basalt fiber filaments are disposed in the first rubber sleeve;

[0008] A plurality of outer strand steel ropes are twisted around the outer surface of the composite center strand, wherein the outer strand steel ropes include a center core wire, a plurality of inner strand steel wires are twisted around the center core wire, and a plurality of outer strand steel wires are twisted around the inner strand steel wire.

[0009] Furthermore, the diameters of the central core wire, the outer strand steel wire and the inner strand steel wire decrease in sequence.

[0012] Furthermore, the inner strands of the steel wire are twisted clockwise, and the outer strands of the steel wire are twisted counterclockwise.

[0013] Furthermore, the longitudinal sections of the basalt fiber filaments and the carbon fiber core filaments are both hexagonal.

[0014] Furthermore, the inner steel wire and the outer steel wire are both formed by twisting a plurality of fine steel wires together to form strands.

[0015] Furthermore, a fourth rubber sleeve is provided on a plurality of the outer steel wires.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0026] like Figure 1-Figure 5 As shown, a zinc-aluminum alloy steel wire rope proposed in one embodiment of the present application includes:

[0027] The composite core strand 1 includes a first rubber sheath 101, within which are disposed a plurality of basalt fiber filaments 102. The basalt fiber filaments 102 are continuous fibers drawn from natural basalt. The basalt material is melted at 1450°C to 1500°C and then drawn at high speed through a platinum-rhodium alloy drawing bushing. This fiber is 5 to 10 times stronger than steel, ensuring both strength and good bending properties while weighing approximately one-third the weight of steel of the same volume. By bundling the plurality of basalt fiber filaments 102 through the first rubber sheath 101 to form the composite core strand 1, which serves as the core of the steel wire rope, the strength of the steel wire rope is ensured while also ensuring its bending properties, thereby extending its service life.

[0028] A plurality of outer strand steel ropes 2 are twisted around the outer surface of the composite center strand 1. The outer strand steel ropes 2 include a central core wire 201, on which a plurality of inner strand steel wires 202 are twisted, and on which a plurality of outer strand steel wires 203 are twisted. The outer strand steel ropes 2 are formed by using the central core wire 201 as the steel rope core, twisting a plurality of inner strand steel wires 202 around its outer surface, and then twisting the outer strand steel wires 203 around the outer surface of the inner strand steel wires 202. The outer strand steel ropes 2 have a central rope core and an inner and outer layer steel wire structure, and have strong tensile strength. The plurality of outer strand steel ropes 2 are twisted around the outer surface of the composite center strand 1, thereby improving the overall strength of the steel rope.

[0029] In this solution, a first rubber sleeve 101 is used to bundle several basalt fiber filaments 102 to form a composite central strand 1, and the central core wire 201, the inner steel wire 202 and the outer steel wire 203 constitute the outer steel rope 2. Several outer steel ropes 2 are twisted around the composite central strand 1 to form a steel wire rope, which not only has strong load-bearing capacity and tensile strength, but also has good bending performance, thereby improving the service life of the steel wire rope.

[0030] like Figure 5 As shown, in some embodiments, the diameters of the center core wire 201, the outer steel wire 203 and the inner steel wire 202 decrease successively, the center core wire 201 has the largest diameter, and plays the main role in load-bearing capacity and tensile strength, the inner steel wire 202 and the outer steel wire 203 play an auxiliary role, and the inner steel wire 202 and the outer steel wire 203 form a structure with the inner side smaller and the outer side larger. After twisting, the outer steel rope 2 is denser and has higher strength as a whole.

[0031] like Figure 5As shown, in some embodiments, the central core wire 201 includes a second rubber sleeve 2011, and a plurality of carbon fiber core wires 2012 are arranged in the second rubber sleeve 2011. The inner strand steel wire 202 is twisted around the second rubber sleeve 2011. Compared with ordinary steel cores, the carbon fiber core wires 2012 can carry 7 to 9 times the tension, while weighing only one-fourth of the equivalent steel wire. By using the second rubber sleeve 2011 to bundle the plurality of carbon fiber core wires 2012 to form the central core wire 201, it not only increases the overall strength of the outer strand steel rope 2, but also does not increase the weight too much when enhancing the overall strength of the steel wire rope, thereby improving practicality.

[0032] like Figure 5 As shown, in some embodiments, a third rubber sleeve 3 is sleeved on a plurality of inner steel wires 202, and the outer steel wires 203 are twisted around the third rubber sleeve 3. Since the inner steel wires 202 and the outer steel wires 203 are both installed by twisting, when the wire rope is subjected to tension and stress, the inner steel wires 202 and the outer steel wires 203 will both shrink inward due to the stress. By providing the third rubber sleeve 3 between the inner steel wires 202 and the outer steel wires 203, direct contact between the two wires, which may cause metal fatigue, is avoided, and wear of the two wires when subjected to stress is reduced, thereby improving practicality.

[0033] like Figure 5 As shown, in some embodiments, the inner steel wire 202 is twisted clockwise and the outer steel wire 203 is twisted counterclockwise. By twisting the inner steel wire 202 clockwise and the outer steel wire 203 counterclockwise, two layers of inner and outer spiral structures are formed, and the two layers of spiral structures have opposite rotation directions. When the wire rope is subjected to load, the stress will be transmitted to the spiral structure, thereby forming spiral stress. The two spiral structures with opposite spirals offset each other's spiral stress, making the spiral structure less likely to loosen, thereby enhancing the overall strength of the wire rope and improving its practicality.

[0034] like Figure 4 and Figure 5 As shown, in some embodiments, the longitudinal sections of the basalt fiber filaments 102 and the carbon fiber core filaments 2012 are both constructed as hexagons. By constructing the longitudinal sections of the two as hexagons, the density coefficient of the two is high after being bundled, and the strength is higher, thereby improving practicality.

[0035] like Figure 2 and Figure 3 As shown, in some embodiments, the inner steel wire 202 and the outer steel wire 203 are formed by twisting a plurality of fine steel wires together into strands. By twisting a plurality of fine steel wires together into strands to form the inner steel wire 202 or the outer steel wire 203, not only the strength of a single strand of the inner steel wire 202 or the single strand of the outer steel wire 203 is improved, but also its toughness is improved, thereby improving the overall strength of the wire rope.

[0036] like Figure 1 and Figure 4 As shown, in some embodiments, a fourth rubber sleeve 4 is provided on several outer steel wires 203. The fourth rubber sleeve 4 can protect the entire steel wire rope to prevent the outer steel wires 203 from being exposed and broken due to wear of other components, thereby improving the overall strength of the steel wire rope.

[0037] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
