Description

Technical Field

[0001] The utility model relates to the technical field of steel wire rope splicing, in particular to a splicable high-toughness steel wire rope. Background Art

[0002] A high-strength wire rope is a structure made of multiple twisted steel wires, combining high strength and high toughness. High strength means it can withstand significant tension without breaking, and its tensile strength is typically much higher than that of ordinary ropes. This is because the wires that make up the wire rope are inherently strong, and through a strategic twisting method, such as double or triple twist, the wires work together to evenly distribute the tension. Many practical applications require very long wire ropes. However, due to production and transportation limitations, wire rope lengths cannot be increased indefinitely. The splicable nature of wire ropes allows shorter wire ropes to be joined to the desired length during installation, making it easier for construction workers to operate.

[0003] Most wire rope splices, such as wire rope clamps, consist of a U-bolt, nut, and clamp. To splice, the ends of two wire ropes are overlapped by a predetermined length, and the wire rope clamp is installed in the overlapped area. The curved portion of the U-bolt fits over the working section of the wire rope. The nut is tightened to secure the clamp to the wire rope. Multiple wire rope clamps are evenly distributed across the overlapped area to connect the two wire ropes.

[0004] In the prior art, when some splicing structures are used to splice wire ropes through wire rope clamps, they can only be used in some occasions where the connection strength requirements are not high, such as auxiliary ropes of small cranes and temporary lifting equipment. The scope of application is limited and the flexibility of the splicing structure is reduced. Therefore, in order to address the above shortcomings, a splicable strong and tough wire rope is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the existing technology and propose a splicable strong toughness wire rope, aiming to improve the problems of insufficient strength, limited scope of application and poor flexibility of the wire rope splicing structure in the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A splicable high-toughness steel wire rope comprises two splicing blocks, wherein sliding holes are provided on the far sides of the two splicing blocks, ropes are slidably connected inside the sliding holes, the adjacent sides of the two ropes are fixedly connected to limit plates, the adjacent sides of the two ropes are sleeved with strong springs, the far sides of the two splicing blocks are slidably connected inside with connecting rings, the two splicing blocks are connected by a connecting assembly, a sealing ring is fixedly connected to one side of the connecting assembly, and a wear-resistant assembly is provided on the outside of the rope.

[0008] Furthermore, the connecting assembly includes two threaded blocks, the adjacent sides of the two threaded blocks are fixedly connected to the twisting block, and the distant sides of the two threaded blocks are respectively fixedly connected to the adjacent sides of the two sealing rings.

[0009] Furthermore, the outer portions of the two threaded blocks on the sides away from each other are respectively threadedly connected to the adjacent sides of the two splicing blocks, and one side of the twisting block is in contact with one side of the splicing block.

[0010] Furthermore, the outside of the sealing ring contacts one side of the limiting plate, and the far sides of the two threaded blocks contact the close sides of the two limiting plates.

[0011] Furthermore, one end of the strong spring is fixedly connected to one side of the interior of the splicing block, and the other end of the strong spring is fixedly connected to one side of the connecting ring.

[0012] Furthermore, the exterior of the limiting plate contacts the interior of one side of the connecting ring, and a plurality of friction blocks are fixedly connected to the exterior of the splicing block.

[0013] Furthermore, the wear-resistant component includes a plastic coating, and the plastic coating is evenly applied on the outside of the rope.

[0014] The utility model has the following beneficial effects:

[0015] In this utility model, the threaded block connects the two splicing blocks, simultaneously driving the sealing ring to squeeze the limit plate, making the connection between the rope and the connecting ring tighter and more secure. When the rope is stressed, the limit plate drives the connecting ring to slide inside the splicing block, causing the powerful spring to generate a rebound force. This rebound force can buffer and absorb instantaneous impact, reducing stress concentration and damage to the splicing joint, thereby increasing the flexibility of the splicing structure and accommodating it in a variety of different work scenarios and equipment.

[0016] In the utility model, the plastic coating applied on the outside of the rope can buffer the external pressure and impact force borne by the steel wire rope during operation to a certain extent, help reduce fatigue damage of the steel wire, improve the fatigue resistance of the steel wire rope, and withstand more cyclic loading without fatigue fracture.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figures 1 to 3The present invention provides an embodiment of a splicable high-toughness steel wire rope, comprising two splicing blocks 1. The two splicing blocks 1 serve as the main connecting components of the entire splicable high-toughness steel wire rope. The two splicing blocks 1 are each provided with a sliding hole 2 on the far side thereof, and a rope 3 is slidably connected to the inner wall of the sliding hole 2. The two ropes 3 serve as the key parts for bearing tension. The two ropes 3 are fixedly connected to a limit disk 4 on the adjacent side thereof. A strong spring 5 is sleeved on the adjacent side of the outside of the two ropes 3. One end of the strong spring 5 is fixedly connected to the inner side of the splicing block 1, and the other end of the strong spring 5 is tightly fixedly connected to one side of a connecting ring 6. When the rope 3 is subjected to stress, it can effectively buffer and absorb the instantaneous impact force through its own expansion and contraction deformation, reduce the damage to the splicing part caused by stress concentration, and greatly improve the stability and reliability of the entire device. The two splicing blocks 1 are connected to each other on the far side by a connecting ring 6, and the connecting ring 6 is connected to the inside of the splicing block 1 by sliding. The outside of the splicing block 1 is fixedly connected with multiple friction blocks 7 to increase friction. The two splicing blocks 1 are connected by a connecting assembly.

[0025] Reference Figure 1 、 Figure 2 and Figure 4 The connecting assembly includes two threaded blocks 8, and the adjacent sides of the two threaded blocks 8 are fixedly connected with a twisting block 9, which is convenient for the operator to perform the twisting operation. The distant sides of the two threaded blocks 8 are respectively fixedly connected to the adjacent sides of the two sealing rings 10. The sealing rings 10 are made of wear-resistant and corrosion-resistant rubber material with good elasticity and sealing performance. During the installation process, when the threaded block 8 is threadedly connected to the adjacent side of the splicing block 1 and gradually tightened, it will drive the sealing ring 10 to move synchronously. The sealing ring 10 applies a uniform and stable extrusion force to the limit plate 4 until the limit plate 4 is firmly installed in the inside of the connecting ring 6. At this time, the two sliding holes 2 are precisely docked, completing the entire installation process, and the sealing ring 10 can effectively prevent impurities such as dust and moisture from entering the splicing, thereby extending the service life of the device. The outside of the rope 3 is provided with a wear-resistant component, which includes a plastic coating 11. The plastic coating 11 is evenly and densely applied to the outside of the rope 3 and has excellent wear resistance and impact resistance. When external pressure and impact force act on the rope 3, the plastic coating 11 can buffer and disperse these forces to a certain extent, reducing the direct impact of pressure on the steel wire inside the rope 3.

[0026] Working Principle: During initial installation, first place the limit plate 4, guided by the rope 3, into the interior space of the connecting ring 6. Then manually twist the screwing block 9, which drives the threaded block 8 to rotate, gradually tightening the threaded block 8 in the internal threaded channel of the splicing block 1. During this process, the sealing ring 10 is also driven to move synchronously, exerting a squeezing force on the limit plate 4 until the limit plate 4 is firmly installed in the interior of the connecting ring 6. At this point, the two sliding holes 2 are precisely aligned, completing the entire installation process.

[0027] When this splicable high-toughness steel wire rope is put into use, if the rope 3 is subjected to external tension, the rope 3 will pull the limit plate 4 to slide inside the connecting ring 6. The sliding of the limit plate 4 further drives the connecting ring 6 to slide within the internal space of the splicing block 1. This process causes the strong spring 5 to deform under stress and accumulate rebound force. At the same time, the plastic coating 11 applied to the outside of the rope 3 begins to take effect. When external pressure and impact force act on the rope 3, the plastic coating 11 can buffer and disperse these forces to a certain extent, reducing their direct impact on the steel wire inside the rope 3, allowing the steel wire rope to withstand more cyclic loading and avoid fatigue fracture. The rebound force generated by the strong spring 5 can effectively buffer and absorb instantaneous impact force, preventing excessive stress from concentrating on the splicing point and causing damage.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
