Abstract
Description
Technical Field
[0001] This utility model relates to the field of rigging technology, specifically to a pressed steel wire rope rigging. Background Technology
[0002] Wire rope slings, as an important load-bearing component in engineering, are widely used in port machinery, construction engineering, mining, shipbuilding, and heavy lifting. Using wire rope as the core load-bearing element, they are lifting tools that form closed loops or specific structures through end pressing or weaving, possessing advantages such as high strength, good flexibility, and impact resistance.
[0003] Traditional wire rope slings mostly adopt a fixed structure, with both ends fixed by sleeve crimping or wedge joints. The length and tension cannot be adjusted after installation, which has obvious limitations in practical applications. For example, after pre-tensioning or long-term loading, the wire rope may gradually elongate, causing the original tension to decrease and affecting the structural stability. In addition, different lengths of slings need to be replaced under different working conditions, increasing equipment inventory and management costs.
[0004] Therefore, a pressing steel wire rope tool was designed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a pressing steel wire rope tool to solve the problems mentioned in the background art above.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire rope pressing tool, comprising at least two fixed rods, with a wire rope mounted on each fixed rod. Adjustment mechanisms are fixedly mounted at both ends of the wire rope, and these mechanisms are used to adjust the tension of the wire rope. A support column is fixedly mounted at the end of the adjustment mechanism away from the wire rope, and a base is fixedly mounted at one end of the support column. A threaded sleeve is fixedly mounted at the end of the support column away from the base, and the threaded sleeve is threadedly connected to the fixed rod. An auxiliary mechanism is fixedly mounted on the fixed rod, and this auxiliary mechanism is used to clamp the wire rope. The auxiliary mechanism includes an extension block fixedly connected to the fixed rod, and a mounting frame is fixedly mounted on the extension block. A connector is fixedly mounted on the mounting frame, and a pulley is rotatably mounted on the connector via a bearing. The pulley has a V-groove, and the V-groove abuts against the wire rope.
[0007] Furthermore, the adjustment mechanism includes a connecting rod fixedly connected to the wire rope, and a connecting section is provided on the connecting rod. A threaded rod is fixedly provided on the connecting section, and an adjustment sleeve is provided on the outer thread of the threaded rod.
[0008] Through the above structural design, the cooperation between the connecting rod and the adjusting sleeve provides a simple and reliable tension adjustment path.
[0009] Furthermore, the adjusting sleeve is threaded with a threaded rod II, and a connecting section II is fixedly provided at the end of the threaded rod II away from the adjusting sleeve. A stabilizing rod is provided on the connecting section II, and a connecting ring is sleeved on the outer side of the stabilizing rod. A fixing block is provided on the connecting ring, and the fixing block is fixedly connected to the support column.
[0010] Through the above structural design, the cooperation between the stabilizing rod and the connecting ring can effectively prevent the adjustment mechanism from rotating or loosening when under force, thus enhancing the overall stability.
[0011] Furthermore, the threads of threaded rod one and threaded rod two have opposite directions of rotation, and threaded rod one and threaded rod two are respectively threaded into the two ends of the adjusting sleeve.
[0012] Through the above structural design, the opposite spiral thread design allows for bidirectional synchronous adjustment by rotating a single adjusting sleeve, significantly improving adjustment efficiency.
[0013] Furthermore, an anti-slip pad is fixedly provided on the bottom of the base, and the anti-slip pad is made of rubber material.
[0014] Through the above structural design, the rubber anti-slip pad increases the friction with the contact surface and plays a buffering role, preventing the base from sliding and ensuring the placement stability of the entire rigging.
[0015] Furthermore, the wire rope has an independent wire rope core structure.
[0016] Through the above structural design, the independent wire rope core structure endows the rigging with higher flexibility, resistance to bending fatigue and impact load capacity.
[0017] Furthermore, the surface of the wire rope is provided with a galvanized layer.
[0018] Through the above structural design, the galvanized layer can effectively isolate corrosive media, greatly enhancing the corrosion resistance and service life of the wire rope in harsh environments.
[0019] Furthermore, the ends of the wire rope are fixed by pressing with aluminum alloy sleeves.
[0020] Through the above structural design, the aluminum alloy sleeve pressing and fixing method forms a high-strength, unbroken end connection that is firm, reliable and has strong resistance to pull-out.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] This pressed wire rope rigging, through an adjustment mechanism consisting of a threaded rod with opposite rotation and an adjusting sleeve, achieves bidirectional, precise, and efficient adjustment of the rigging tension with a single rotation. This greatly improves operational convenience and solves the problems of inconvenient adjustment and easy failure of traditional structures. At the same time, by integrating an auxiliary mechanism with a V-groove pulley, it effectively guides and supports the wire rope, reducing friction loss and bending stress with the fixing parts and extending service life. Combined with the design of an independent rope core, galvanized layer, crimped end, and anti-slip base, the rigging is endowed with higher load-bearing strength, excellent corrosion resistance, reliable end connection, and environmental adaptability, ultimately forming a high-performance rigging product that is easy to adjust, stable, durable, and widely applicable.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] like Figures 1-4As shown, this utility model discloses a steel wire rope pressing tool, including at least two fixed rods 1, and a steel wire rope 11 is provided on the fixed rod 1. An adjustment mechanism 2 is fixedly provided at both ends of the steel wire rope 11, and the adjustment mechanism 2 is used to adjust the tension of the steel wire rope 11. A support column 12 is fixedly provided at the end of the adjustment mechanism 2 away from the steel wire rope 11, and a base 13 is fixedly provided at the end of the support column 12. A threaded sleeve 10 is fixedly provided at the end of the support column 12 away from the base 13, and the threaded sleeve 10 is threadedly connected to the fixed rod 1. An auxiliary mechanism 3 is fixedly provided on the fixed rod 1, and the auxiliary mechanism 3 is used to clamp the steel wire rope 11. The auxiliary mechanism 3 includes an extension block 30 fixedly connected to the fixed rod 1, and a mounting frame 31 is fixedly provided on the extension block 30. A connector 32 is fixedly provided on the mounting frame 31, and a pulley 33 is rotatably provided on the connector 32 through a bearing. A V-groove is provided on the pulley 33, and the V-groove abuts against the steel wire rope 11.
[0030] The adjusting mechanism 2 includes a connecting rod 20 fixedly connected to the wire rope 11, and a connecting section 21 is provided on the connecting rod 20. A threaded rod 22 is fixedly provided on the connecting section 21, and an adjusting sleeve 23 is provided on the outer thread of the threaded rod 22. When the adjusting sleeve 23 is rotated, the threaded rod 22 is driven and generates axial displacement relative to the adjusting sleeve 23, thereby directly pulling or releasing the wire rope 11, realizing precise fine adjustment of tension, transforming complex tension adjustment into a simple rotation operation. It not only has high mechanical efficiency, but also has fewer parts, a compact structure, and strong reliability, greatly facilitating on-site installation and subsequent maintenance.
[0031] The adjusting sleeve 23 is threaded with a threaded rod 24, and a connecting section 25 is fixedly installed at the end of the threaded rod 24 away from the adjusting sleeve 23. A stabilizing rod 26 is installed on the connecting section 25, and a connecting ring 27 is sleeved on the outside of the stabilizing rod 26. A fixing block 28 is installed on the connecting ring 27, and the fixing block 28 is fixedly connected to the support column 12. The connecting section 25 cooperates with the stabilizing rod 26 and the connecting ring 27, allowing the mechanism to self-adaptively deflect within a certain range, avoiding the formation of harmful bending stress. At the same time, it firmly connects the adjusting mechanism 2 to the support column 12, effectively dispersing and transmitting the huge tension applied to the wire rope 11 to the entire support structure. This greatly suppresses the possible accidental rotation or loosening of the adjusting sleeve 23 under stress, ensuring the absolute stability and safety of the rigging under long-term, high-load working conditions.
[0032] The threads of threaded rod 22 and threaded rod 24 are opposite in direction, and threaded rod 22 and threaded rod 24 are respectively threaded into both ends of adjusting sleeve 23. When the operator rotates adjusting sleeve 23 in one direction, the two threaded rods will move synchronously inward or outward, thereby realizing bidirectional linear adjustment of the total length of the rigging. This avoids the cumbersome operation of rotating the two end parts separately, simplifies the adjustment process into one action, and improves the efficiency and convenience of the adjustment operation.
[0033] The bottom of the base 13 is fixedly equipped with an anti-slip pad, which is made of rubber material. The high coefficient of friction of the rubber material can generate strong adhesion, effectively resist the horizontal sliding force, and prevent the base 13 from shifting when lifting heavy objects or being subjected to vibration and impact. At the same time, the rubber pad also has a certain buffering and shock absorption performance, which can absorb some impact energy and protect the base 13 and its connecting parts from damage caused by rigid collision.
[0034] The steel wire rope 11 has an independent steel wire rope core structure, which is usually a strand core IWR or steel wire core IWRC structure. Compared with the fiber core FC structure, it has higher compressive strength, anti-rotation performance and fatigue resistance. When subjected to huge loads, it can effectively resist the relative displacement of the internal steel wire strands and the torsional deformation of the rope, maintain the stability of the structural shape, and enhance the load-bearing safety and service life of the rigging.
[0035] The surface of the wire rope 11 is provided with a galvanized layer. The coating can effectively isolate the contact between the wire rope base and corrosive media such as water vapor, salt spray, acid and alkali, and prevent rust. For rigging used in outdoor, marine, humid or industrial environments with corrosive chemicals, it can significantly delay the strength loss and surface damage of the wire rope 11 caused by rust, thereby ensuring its long-term reliable operation and extending its service life.
[0036] The ends of the wire rope 11 are fixed by pressing with aluminum alloy sleeves. The aluminum alloy sleeves are plastically deformed by huge pressure, tightly wrapping and biting the wire rope strands, effectively preventing the rope ends from unraveling and the load from slipping off. It has the advantages of strong pull-out resistance, good fatigue performance, smooth appearance and not easy to snag, ensuring the safety of the force transmission end.
[0037] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
