DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The embodiments described below are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0023] Referring to Figures 1 to 4 , this embodiment provides a pressing rigging for ultra-high strength steel ropes, which includes a steel wire rope 10 and a fixing assembly 20. The steel wire rope 10 includes an inner layer strand formed by roll compaction, a predetermined number of outer layer strands formed by roll compaction, and a predetermined number of high-strength material layers arranged outside the outer layer strands. Sleeve rings 30 are sleeved on both ends of the steel wire rope 10, and fixing sleeves 40 are arranged on the outer sides of the two ends; the fixing assembly 20 is buckled outside the sleeve ring 30. The fixing assembly 20 includes a first fixing member 21, a second fixing member 22 symmetric to the first fixing member 21, and two nuts 23. Two semi-circular through holes 24 are arranged in the middle of the first fixing member 21 and the second fixing member 22. A first transverse tooth group 25, a vertical tooth group 26, and a second transverse tooth group 27 are sequentially arranged along the side wall of the semi-circular through hole 24 from top to bottom. Both ends of the first fixing member 21 and the second fixing member 22 are set as semi-circular platform structures 28 with diameters gradually increasing towards the center at the ends. External threads are arranged on the outer sides of the semi-circular platform structures 28. The inner part of the nut 23 is set as a conical thread. When the fixing assembly 20 is installed, the nut 23 is screwed onto the outer sides of the two ends of the first fixing member 21 and the second fixing member 22.

[0024] Referring to Figure 3 , preferably, both the first transverse tooth group 25 and the second transverse tooth group 27 include multiple rows of parallel transverse racks, and a plurality of protrusions are arranged in the length direction of the transverse racks. This enables the fixing assembly 20 to provide stronger transverse biting force and stability during the fixing process of the steel wire rope 10. The multiple rows of parallel transverse racks increase the contact area and friction force, effectively preventing the fixing member from sliding or loosening under stress, and ensuring the tight fixing of the end of the steel wire rope 10. The plurality of protrusions arranged on the transverse racks further enhance the grasping force of the fixing assembly 20, enabling the fixing assembly 20 to be more firmly buckled outside the sleeve ring 30, improving the safety and reliability of the entire rigging. Preferably, an anti-slip pad is arranged between the two transverse racks. This further increases the friction force between the fixing assembly 20 and the lock sleeve.

[0025] Referring to Figure 3, preferably, the vertical tooth group 26 includes a plurality of vertical racks arranged in an X shape, and a plurality of protrusions are provided on the vertical tooth group 26. The design of the X-shaped vertical racks increases the contact area and friction between the fixing component 20 and the lasso, making the grip of the fixing component 20 on the steel wire rope 10 more firm. Moreover, the X-shaped structure can evenly disperse the force in multiple directions, improving the tensile strength of the fixing component 20, reducing the stress concentration phenomenon, and effectively preventing the fixing component 20 from sliding or loosening under stress. In addition, the cooperation between the vertical tooth group 26 and the horizontal tooth group further enhances the biting force of the fixing component 20, ensuring the stability and safety of the steel wire rope 10 in a high-strength working environment.

[0026] Refer to Figure 4 , preferably, the fixing sleeve 40 includes a fixing sleeve main body 41 with a through accommodation through hole provided in the middle. Four fixing columns 42 are evenly distributed on the outer periphery of the fixing sleeve main body 41. The fixing columns 42 are provided with threaded holes extending from the side far from the fixing sleeve main body 41 to the inner side of the fixing sleeve main body 41. A counteracting screw 43 is inserted into the threaded hole, and an anti-slip rubber pad is provided at the end of the counteracting screw 43. When the fixing sleeve 40 of the present application is used, the steel wire rope 10 is passed through the through accommodation through hole of the fixing sleeve main body 41, and then the counteracting screw 43 is rotated. The counteracting screw 43 moves inward, and the anti-slip rubber pad at the end of the counteracting screw 43 contacts the steel wire rope 10 until the counteracting screw 43 can no longer be rotated, and the end of the steel wire rope 10 is locked by the fixing sleeve 40. It also prevents the end of the lasso from slipping out of the fixing component 20.

[0027] Preferably, the high-strength material layer includes a corrosion-resistant layer, a high-strength fiber layer, a flexible material layer, and a wear-resistant layer arranged in sequence from the inside to the outside. The corrosion-resistant layer effectively protects the steel wire rope 10 from the corrosion effect in the environment, extends its service life and improves its durability. Secondly, the high-strength fiber layer enhances the overall strength and tensile performance of the steel wire rope 10, making it more suitable for use under high load and complex working conditions. The flexible material layer helps to reduce vibration and noise, improving the comfort and safety of use. Finally, the wear-resistant layer protects the surface of the steel wire rope 10 from wear, especially avoiding damage caused by friction during long-term use, thereby further extending the life and stability of the steel wire rope 10. Therefore, the design of the high-strength material layer strengthens the performance of the ultra-high-strength steel wire rope pressing rigging, making it perform excellently in complex engineering environments and meeting the requirements of various industrial applications with high strength. It should be noted that in the present application, the corrosion-resistant layer is a thermoplastic polyester composite corrosion-resistant layer; the high-strength fiber layer is a polyester fiber or ultra-high molecular weight polyethylene fiber; the flexible material layer is a polyurethane flexible material layer; the wear-resistant layer is a resin material wear-resistant layer.

[0028] Refer to Figure 2, preferably, the first fixing member 21 matches the external thread provided at the end of the second fixing member 22, facilitating the screwing in of the nut 23. Preferably, the diameter of the semi-circular through hole 24 is less than or equal to the diameter of the wire rope 10, ensuring the tight combination of the fixing assembly 20 and the wire rope 10, thereby enhancing the safety during use. Preferably, galvanized layers are provided on both the outer strands and the outer side of the inner strands. The galvanized layer can effectively prevent the wire rope 10 from being corroded by the atmosphere, moisture, and chemical substances during use. Especially in a humid or chemically corrosive environment, the galvanized layer can extend the service life of the wire rope 10, reduce the rust and corrosion damage on the surface of the rope, and maintain the integrity and strength of its structure.

[0029] It should be noted that when installing the fixing assembly 20 of the present application, the wire ropes 10 at both ends of the collar 30 of the wire rope 10 are buckled into the corresponding semi-circular through holes 24 between the first fixing member 21 and the second fixing member 22. The first fixing member 21 and the second fixing member 22 cooperate to form two circular through holes. Then, the semi-cone structures 28 on both sides are combined to form a cone structure. After that, the nut 23 with a conical thread is screwed in, and the fixing assembly 20 is installed into the lasso. It should be noted that the design of the conical thread allows the fixing assembly 20 to have a greater tolerance for the diameter of the wire rope 10. Even if the diameter of the wire rope 10 is slightly larger than the diameter of the circular through hole, the safety fixing can still be ensured by adjusting and tightening the nut 23. This design can adapt to wire ropes 10 of different diameters. Secondly, the method of using a cone structure and a nut 23 with a conical thread provides stronger locking force and stability, which can effectively prevent the fixing assembly 20 from loosening or sliding during use, ensuring a durable and safe fixing under various stress and environmental conditions. Thirdly, when the nut 23 with a conical thread is screwed with the matching cone structure, due to the change in the thread diameter, an axial component force will be generated, which helps to enhance the self-locking performance of the thread connection and makes the connection more stable. In addition, the design of the conical thread also helps to disperse stress, reduce the stress concentration in the thread part, and thus improve the fatigue life of the thread connection. Of course, it can also simplify the installation process and reduce the installation time.

[0030] The utility model provides a pressed sling made of ultra-high strength steel rope, which comprises a steel wire rope 10 and a fixing component 20. The steel wire rope 10 is composed of an inner layer strand and an outer layer strand formed by roll compaction, and a high-strength material layer arranged outside the outer layer strand, which significantly enhances the tensile strength and durability of the steel wire rope 10 and reduces the fracture risk caused by tensile force. Fixing sleeves 40 are arranged on the outer sides of the two ends of the steel wire rope 10, ensuring that the ends of the steel wire rope 10 are fixed more tightly, preventing the phenomenon of break-off under stress, and improving the safety and reliability of use. The first fixing piece 21 and the second fixing piece 22 included in the fixing component 20 provide a multiple locking mechanism through the semi-circular through hole 24 in the middle and the first transverse tooth group 25, vertical tooth group 26 and second transverse tooth group 27 on the side wall thereof, effectively preventing sliding and loosening and ensuring the stability of the installation of the fixing component 20. The two ends of the first fixing piece 21 and the second fixing piece 22 are designed as frustum of a cone structures 28, and external threads are arranged on the outside. Matching with the conical threads inside the nut 23, during installation, by screwing in the nut 23, the fixing component 20 can be quickly and firmly fixed on the outside of the collar 30. In addition, when the position of the locking sleeve needs to be changed, only the fixing component 20 needs to be adjusted, so that the sling is not only applicable to heavy objects with conventional shapes and weights, but also can meet the lifting requirements of some objects with special shapes and specific lifting requirements, significantly improving the applicable range and use flexibility of the sling. Therefore, the pressed sling made of ultra-high strength steel rope of the utility model significantly improves the strength, stability and applicability of the steel rope pressed sling, meeting various requirements in practical applications.

[0031] The above-disclosed are only several preferred embodiments of the present utility model, and of course, the scope of rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present utility model still fall within the scope covered by the present utility model.
