Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, and in particular relates to a steel wire rope. Background Art

[0002] With the development of society, large-scale mechanical equipment has gradually increased, and large-scale lifting machinery is indispensable among them. In the construction industry, large-scale lifting machinery is usually used to lift heavy objects from a lower position to a higher position. In the process of lifting heavy objects, the tension is mainly borne by the wire rope of the lifting machinery. Since the wire rope bears a large load and bears the load for a long time, it will break, causing huge losses to users. How to avoid wire rope breakage is a problem that needs to be solved in related technologies. Utility Model Content

[0003] In order to solve the problems raised in the above background technology, the utility model provides a steel wire rope, which can reduce the risk of the steel wire rope breaking.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel wire rope, characterized in that it includes a first rope body and a second rope body, the first rope body has multiple ropes, which are circumferentially wound around the outside of the second rope body, and the ends of the multiple first rope bodies are fixed on a tightening device, which is an annular structure, and the inner diameter of the tightening device is provided with a thread, which cooperates with the thread set on the outer periphery of the extension part of the second rope body.

[0005] In the above technical solution, preferably, there are two tightening devices, which are respectively arranged on both sides of the plurality of first rope bodies.

[0006] In the above technical solution, preferably, the threads of the inner diameters of the two fastening devices rotate in opposite directions.

[0007] In the above technical solution, preferably, there are two extension parts, which are respectively arranged on both sides of the second rope body.

[0008] In the above technical solution, preferably, the threads arranged on the outer peripheries of the two extensions rotate in opposite directions.

[0009] In the above technical solution, preferably, the plurality of second rope bodies are respectively fixed in the fixing holes of the tightening device.

[0010] The utility model aims to address the deficiencies of the prior art and provide a steel wire rope, which comprises a first rope body and a second rope body. The first rope body has a plurality of roots, which are circumferentially wound around the outside of the second rope body. The ends of the plurality of first rope bodies are fixed on a tightening device. The inner diameter of the tightening device is provided with a thread, which cooperates with the thread arranged on the outer periphery of the extension portion of the second rope body. By rotating the tightening device, the first rope body circumferentially wound around the outside of the second rope body can be wound more firmly, thereby avoiding a reduction in the toughness of the steel wire rope due to the loosening of the first rope body. In addition, the arrangement of the plurality of rope bodies allows the second rope body to bear the load when the first rope body breaks, thereby reducing the risk of the steel wire rope breaking.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figures 1 to 4 As shown, the utility model provides a steel wire rope, including a first rope body 20 and a second rope body 30. The first rope body 20 has multiple ends, which are circumferentially wound around the outside of the second rope body 30. The ends of the multiple first rope bodies 20 are fixed on a tightening device 10. The tightening device 10 is an annular structure. The inner diameter 102 of the tightening device 10 is provided with a thread, which cooperates with the thread set on the outer periphery 401 of the extension part 40 of the second rope body 30.

[0018] Using the above solution: Figure 1 and Figure 3As shown, multiple first rope bodies 20 are circumferentially wound around the outside of the second rope body 30. Under the condition of equal distance, the first rope body 20 is longer than the second rope body 30, so that when the first rope body 20 bears the load, the second rope body 30 is not subjected to stress. Therefore, when the first rope body 20 breaks, the second rope body 30 is subjected to stress, thereby reducing the risk of wire rope breakage as a whole.

[0019] like Figure 1 As shown, there are two fastening devices 10, which are respectively arranged on both sides of the plurality of first rope bodies 20.

[0020] The above solution is adopted: by providing two tightening devices 10, it is prevented that the multiple first rope bodies 20 that are wound are loosened, thereby reducing the toughness of the steel wire rope.

[0021] like Figure 2 As shown, the threads of the inner diameters 102 of the two fastening devices 10 rotate in opposite directions.

[0022] By adopting the above solution, when the two tightening devices 10 with opposite thread rotation directions rotate respectively, the wound multiple first rope bodies 20 can be wound more tightly, thereby enhancing the toughness of the steel wire rope.

[0023] Using the above solution: Figure 2 and Figure 4 As shown, there are two extension parts 40 , which are respectively arranged on both sides of the second rope body 30 .

[0024] The threads arranged on the outer circumferences 401 of the two extensions 40 rotate in opposite directions.

[0025] The plurality of first rope bodies 20 are respectively fixed in the fixing holes 101 of the fastening device 10 .

[0026] The first rope body 20 is fixed by a fixing hole 101 provided on the fastening device 10. When in use, the fastening device 10 can be rotated at any time, so that the first rope body 20 rotates with the fastening device 10 due to the fixing effect, so that the first rope body 20 is wound more tightly, thereby enhancing the tension of the first rope body 20.
