Description

Technical Field

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

[0002] Wire ropes are usually composed of wire bundles and rope cores. Multiple strands of wire bundles are evenly twisted on the outside of the rope core. After the wire ropes are twisted, they usually need to be soaked in grease. Grease can not only reduce the friction caused by movement and expansion and contraction, enhance the flexibility of the wire rope, but also provide internal and external corrosion protection for the wire rope. When the wire rope is used in a relatively harsh environment, scratches often occur, which causes the grease to fall off and can no longer protect the wire rope. This causes the wire rope to rust and break prematurely, seriously affecting the service life of the wire rope.

[0003] By regreasing steel wire ropes that lack grease, the service life of the steel wire ropes can be extended. In the prior art, the regreasing of steel wire ropes is generally done manually, and the grease is applied to the steel wire ropes with a brush or other water-absorbing tools. However, the manual efficiency is slow. When the steel wire ropes are long and there are many of them, it often takes a lot of time to regreasing, which is inconvenient and time-consuming. In order to reasonably improve this problem, the present application proposes a composite steel wire rope. Summary of the Invention

[0004] The purpose of the present application is to solve the technical problem that in the prior art, grease replenishment of steel wire ropes is generally performed manually, and grease is applied to the steel wire ropes by means of a brush or other water-absorbing tools. However, the manual efficiency is slow, and when the steel wire ropes are long and in large numbers, a lot of time is often required for greasing, which is inconvenient, time-consuming and labor-intensive. The present application provides a composite steel wire rope.

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

[0006] A composite steel wire rope comprising:

[0007] A rope core having a plurality of steel wire bundles wound in a spiral shape around its circumference, wherein: the rope core includes a central strand having a plurality of outer core strands wound in a spiral shape around its circumference;

[0008] The grease supply tube is arranged outside the central strand and inside the outer core strand. The grease supply tube has toughness and a feed port is provided at its end. A plurality of grease outlet holes are evenly distributed around the grease supply tube.

[0009] Furthermore, a cavity is formed between two adjacent outer core strands and the central strand, and the cavity extends along the thread direction of the outer core strand. The number of grease-filling tubes is the same as the number of cavities, and multiple grease-filling tubes are respectively arranged in multiple cavities.

[0010] Furthermore, the contact portions of adjacent outer core strands are not located in the grease outlet direction of the grease outlet hole.

[0011] Furthermore, the plurality of grease outlet holes are spirally arranged on the outside of the grease supply tube, and the axis of the central strand is located in the grease outlet direction of the plurality of grease outlet holes.

[0012] Furthermore, a wear-resistant sleeve is installed on the outer side of the grease supply tube.

[0013] Furthermore, the wear-resistant sleeve is woven from ultra-high molecular weight polyethylene fibers.

[0014] Furthermore, a steel wire mesh is provided on the outer side of the grease replenishing tube.

[0015] Furthermore, the wear-resistant sleeve is wrapped with a steel wire mesh.

[0016] The beneficial effects of the present application are as follows: the present application adopts the design of a grease filling tube. After the grease filling tube is filled, the grease filling tube bends along with the center strand. At this time, the grease can be squeezed out from the grease outlet and grease the rope core. Compared with conventional grease filling methods, such a design can improve the grease filling efficiency of the wire rope, effectively reduce the time wasted in greasing the wire rope, and is convenient, easy to use and practical.

[0021] 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.

[0022] like Figure 1-Figure 3 As shown, a composite steel wire rope proposed in one embodiment of the present application includes:

[0023] A rope core 1 is provided with a plurality of steel wire bundles 2 wound in a spiral shape around its circumference. The steel wire bundles 2 are rope strands twisted from a plurality of steel wires. The rope core 1 includes a central strand 3, and a plurality of outer strands 4 are wound in a spiral shape around its circumference. In this application, the central strand 3 and the outer strands 4 are each formed by twisting six steel wires around one steel wire. There are six outer strands 4, which are twisted around the central strand 3 to form the rope core 1.

[0024] The grease supply pipe 5 is provided with a grease supply port 6 at its end, and a plurality of grease outlet holes 7 are evenly distributed on the circumference of the grease supply pipe 5. The grease outlet holes 7 are small in diameter. When the grease outlet holes 7 are not affected by external forces, the hole walls of the grease outlet holes 7 are in a close contact state, and the grease is not easy to pass through the grease outlet holes 7. The grease supply pipe 5 can be filled with grease through the grease supply port 7. At this time, the air in the grease supply pipe 5 can be squeezed out from the grease outlet holes 7 by the viscous grease. It should be specifically explained here that the wire rope is generally not easy to bend during use. The bent part of the wire rope often contacts the equipment. After the grease supply pipe 5 is filled, the grease supply pipe 5 bends with the central strand 3, and the grease can be squeezed out from the grease outlet holes 7 to replenish the rope core 1. Compared with conventional grease supply methods, this design can improve the grease supply efficiency of the wire rope, effectively reduce the time wasted in grease supplying, and is convenient, easy to use and practical.

[0025] The present application adopts the design of a grease replenishing tube 5. After the grease replenishing tube 5 is filled, the grease replenishing tube 5 bends along with the center strand 3. At this time, the grease can be squeezed out from the grease outlet 7 and replenish the rope core 1. Compared with conventional grease replenishing methods, such a design can improve the grease replenishing efficiency of the wire rope, effectively reduce the time wasted in greasing the wire rope, and is convenient, easy to use and practical.

[0026] like Figure 1 and Figure 3 As shown, in some embodiments, a cavity 8 is formed between two adjacent outer core strands 4 and the center strand 3, and the cavity 8 extends along the thread direction of the outer core strand 4. The number of grease-filling tubes 5 is consistent with the number of cavities 8, and multiple grease-filling tubes 5 are respectively arranged in multiple cavities 8. With this design, when the outer core strand 4 and the center strand 3 are bent, the grease-filling tube 5 is not easily squeezed by the two, so that the grease-filling tube 5 is not easily damaged.

[0027] like Figure 1 and Figure 3 As shown, in some embodiments, the contact parts of adjacent outer core strands 4 are not located in the grease outlet direction of the grease outlet hole 7. During use, dust is easily attached to the surface of the steel wire bundle 2. When the steel wire bundle 2 and the rope core 1 are bent, the dust will inevitably pass through the contact parts of the adjacent outer core strands 4 and come into contact with the wear-resistant sleeve 9. This design makes the grease outlet hole 7 not easily affected by dust.

[0028] like Figure 1 and Figure 3 As shown, in some embodiments, multiple grease outlet holes 7 are spirally arranged on the outside of the grease supply tube 5, and the axis of the central strand 3 is located in the grease outlet direction of the multiple grease outlet holes 7. Since the direction of dust entry is from the outside to the inside, such a design can minimize the impact of dust on the grease outlet holes 7.

[0029] like Figure 3 As shown, in some embodiments, a wear-resistant sleeve 9 is installed on the outside of the grease supply tube 5, so as to separate the grease supply tube 5 from the central strand 3 and the outer core strand 4, making it less likely to be worn.

[0030] like Figure 3 As shown, in some embodiments, the wear-resistant sleeve 9 is woven from ultra-high molecular weight polyethylene fibers, has good wear resistance, and is not easily damaged. After the grease contacts the wear-resistant sleeve 9 through the grease outlet 7, the wear-resistant sleeve 9 can be moistened with the grease, so that the center strand 3 and the outer core strand 4 can be replenished with grease through the wear-resistant sleeve 9.

[0031] like Figure 3 As shown, in some embodiments, a steel wire mesh 10 is provided on the outside of the grease supply tube 5. The steel wire mesh 10 is cylindrical, has high toughness, and can be quickly reset after deformation. The steel wire mesh 10 is designed to support the grease supply tube 5 so that the inner walls of the grease supply tube 5 are not easily attached to each other, so as to facilitate the replenishment of grease.

[0032] As shown in FIG3 , in some embodiments, the wear-resistant sleeve 9 wraps the steel wire mesh 10 . This design can separate the steel wire mesh 10 from the grease supply tube 5 , making it less likely to be worn by the steel wire mesh 10 .

[0033] 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.
