Description

Technical Field

[0001] This utility model relates to the field of wire rope, and in particular to a wire rope with a protective structure. Background Technology

[0002] A steel wire rope is a helical bundle of steel wires twisted according to specific rules, meeting requirements for mechanical properties and geometric dimensions. It typically consists of steel wires, a core, and lubricant. It is formed by twisting multiple layers of steel wires into strands, then, with the core as the center, winding a certain number of strands into a helical shape. It features high strength, light weight, stable operation, resistance to sudden breakage, and reliable performance. There are various types of steel wire ropes, such as galvanized steel wire ropes (including hot-dip galvanized and electro-galvanized), plastic-coated steel wire ropes, and bright steel wire ropes. Based on the twisting method, they can be classified as single-strand ropes, double-strand ropes, compacted ropes, and sealed steel wire ropes. Furthermore, steel wire ropes can be classified according to their application, such as elevator wire ropes, aviation wire ropes, oilfield wire ropes, and lifting wire ropes. In various applications, wire ropes can transmit long-distance loads, have a high safety factor, are lightweight, easy to carry and transport, can withstand various and variable loads, are wear-resistant, shock-resistant, have good operational stability, and are corrosion-resistant, enabling them to operate normally in harsh environments. Therefore, they are widely used in material handling machinery for lifting, traction, tensioning, and load bearing. During use, wire ropes are often subjected to impacts from external objects, which can easily damage them and reduce their service life. Simultaneously, friction between the wires in the wire rope leads to wear, ultimately reducing its service life. Therefore, a wire rope with a protective structure is needed to ensure a longer service life. Utility Model Content

[0003] The main objective of this invention is to provide a steel wire rope with a protective structure, which 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 steel wire rope with a protective structure includes a steel wire rope body, which is composed of outer steel wires and a central steel wire. Several outer steel wires are woven around the outside of the central steel wire. An inner protective structure is fitted onto the central steel wire. The inner protective structure consists of an inner rubber sleeve, a sponge sleeve, and an outer rubber sleeve. The sponge sleeve is fitted onto the inner rubber sleeve, and the outer rubber sleeve is fitted onto the sponge sleeve. A first rubber plug is filled in the inner gap between two adjacent outer steel wires, and a second rubber plug is filled in the outer gap between two adjacent outer steel wires. An outer protective structure is fitted around the outer sides of several outer steel wires and several second rubber plugs. The outer protective structure consists of a rubber protective sleeve and several rubber airbags, all installed inside the rubber protective sleeve.

[0006] Preferably, the inner rubber sleeve of the inner protective structure is fixedly sleeved on the central steel wire of the steel wire rope body.

[0007] Preferably, the sponge sleeve on the inner protective structure is fixedly connected to the inner rubber sleeve and the outer rubber sleeve.

[0008] Preferably, both the inner rubber sleeve and the outer rubber sleeve of the inner protective structure are provided with several flow holes.

[0009] Preferably, the first rubber plug is fixedly connected to the outer steel wire and the outer rubber sleeve on the inner protective structure, and the second rubber plug is fixedly connected to the outer steel wire and the rubber protective sleeve on the outer protective structure.

[0010] Preferably, the rubber protective sleeve on the outer protective structure has a plurality of mounting cavities, which are arranged in a ring, and the rubber airbag is fixedly installed in the mounting cavities.

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

[0012] By installing an inner protective structure, a first rubber plug, and a second rubber plug on the main body of the wire rope, friction between outer steel wires and between the outer steel wire and the central steel wire can be reduced, thereby reducing wear on the outer and central steel wires and extending the service life of the wire rope main body. Furthermore, by covering the main body of the wire rope with an outer protective structure, the structure can block external objects from impacting the wire rope and weaken the impact force, thus reducing the probability of damage from external impacts and further extending the service life of the wire rope main body.

Detailed Implementation

[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 4As shown, a steel wire rope with a protective structure includes a steel wire rope body 1, which is composed of outer steel wires 2 and a central steel wire 3. Several outer steel wires 2 are woven around the outside of the central steel wire 3. An inner protective structure 4 is fitted onto the central steel wire 3. The inner protective structure 4 consists of an inner rubber sleeve 8, a sponge sleeve 9, and an outer rubber sleeve 10. The sponge sleeve 9 is fitted onto the inner rubber sleeve 8, and the outer rubber sleeve 10 is fitted onto the sponge sleeve 9. A first rubber plug 5 is filled in the inner gap between two adjacent outer steel wires 2, and a second rubber plug 6 is filled in the outer gap between two adjacent outer steel wires 2. An outer protective structure 7 is fitted around the outer sides of the several outer steel wires 2 and the several second rubber plugs 6. The outer protective structure 7 is made of rubber. The system consists of a protective sleeve 12 and rubber airbags 14. Several rubber airbags 14 are installed inside the rubber protective sleeve 12. By setting an inner protective structure 4, a first rubber plug 5, and a second rubber plug 6 on the wire rope body 1, the friction between the outer steel wires 2 and between the outer steel wires 2 and the central steel wire 3 can be reduced, thereby reducing the wear of the outer steel wires 2 and the central steel wire 3 and thus improving the service life of the wire rope body 1. By covering the wire rope body 1 with an outer protective structure 7, the outer protective structure 7 can block foreign objects from impacting the wire rope body 1 and weaken the impact force, thereby reducing the probability of the wire rope body 1 being damaged by foreign objects and ultimately further improving the service life of the wire rope body 1.

[0020] Furthermore, the inner rubber sleeve 8 on the inner protective structure 4 is fixedly sleeved on the central steel wire 3 on the steel wire rope body 1. The sponge sleeve 9 on the inner protective structure 4 is fixedly connected to the inner rubber sleeve 8 and the outer rubber sleeve 10. Both the inner rubber sleeve 8 and the outer rubber sleeve 10 on the inner protective structure 4 are provided with several flow holes 11. The first rubber plug 5 is fixedly connected to the outer steel wire 2 and the outer rubber sleeve 10 on the inner protective structure 4. The second rubber plug 6 is fixedly connected to the outer steel wire 2 and the rubber protective sleeve 12 on the outer protective structure 7. The protective structure 4, the first rubber plug 5, and the second rubber plug 6 can block the outer steel wire 2, the central steel wire 3, and the two adjacent central steel wires 3, thereby reducing the wear of the outer steel wire 2 and the central steel wire 3. During use, lubricating oil is injected into the inner shell of the sponge sleeve 9 on the inner protective structure 4. During use, the lubricating oil adsorbed in the sponge sleeve 9 can flow out through the flow holes 11 on the inner rubber sleeve 8 and the outer rubber sleeve 10, thereby lubricating the outer steel wire 2 and the central steel wire 3, and thus achieving the function of lubricating the outer steel wire 2 and the central steel wire 3.

[0021] Furthermore, the rubber protective sleeve 12 on the outer protective structure 7 has several mounting cavities 13 arranged in a ring. The rubber airbag 14 is fixedly installed in the mounting cavity 13. When an external object impacts the wire rope body 1, the rubber protective sleeve 12 and the rubber airbag 14 on the outer protective structure 7 can block the impacting object. At the same time, when the rubber protective sleeve 12 and the rubber airbag 14 are impacted, they will deform. In the process of deformation, the impact force generated by the impacting object can be weakened, thereby reducing the impact force on the wire rope body 1.
