Description

Technical Field

[0001] The utility model relates to the technical field of spools, in particular to a reinforced spool. Background Art

[0002] The spool, named for its side profile resembling the Chinese character "gong" (meaning "I"), is a core reel device widely used for winding and unwinding operations of winding objects such as cables, wires, and strips. Its main function is to provide an orderly winding carrier for flexible long materials and ensure the orderliness and integrity of the materials during winding, unwinding, storage, and transportation. As a core bearing component for winding and storing wires, spools are widely used in many industrial fields such as metal products, wires and cables, optical fibers and cables, and solar silicon wafer cutting. In metal wire production, it cooperates with stranding machines to realize horizontal paying-off, and forms a spiral structure through rotation of the cylinder, covering all processes such as wire drawing, copper plating, annealing, and bunching.

[0003] The basic structure of existing spools has formed a mature paradigm, with the core consisting of three parts: a wheel plate, a middle cylinder (bobbin), and a core tube (shaft body). Although spools with the above structure are widely used, in practical use, especially when carrying heavy-duty and large-tension wires, a long-standing core contradiction that needs to be solved urgently has been exposed: the contradiction between structural strength and self-weight. If lightweight materials (such as aluminum alloy) or reduced wall thickness are used, although the self-weight can be effectively reduced, the rigidity and strength of the structure are often sacrificed, and reliability is reduced. This causes the spool to easily suffer from cylinder crushing, side plate bulging or overall unstable deformation when bearing huge winding tension. Once deformation occurs, it will not only affect the quality of the wound product, but may even cause production accidents such as jamming and wire breakage, and in severe cases, the spool will be scrapped, bringing economic losses. Conversely, if the wall thickness is increased to improve the load-bearing capacity and anti-deformation capacity of the spool to a certain extent, there are also disadvantages such as increased transportation costs, large inertia, and higher requirements for driving equipment.

[0004] Therefore, it is of great significance to improve and design a reinforced spool that meets the requirements of lightweight. Utility Model Content

[0005] The utility model intends to provide a reinforced spool to solve the contradiction between structural strength and lightweight of the spool, improve the bearing capacity, anti-deformation capacity and connection reliability through optimized design, and reduce the self-weight at the same time.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a reinforced H-beam wheel, comprising a wheel plate, a winding drum, and a core tube. The core tube is connected to the winding drum by spiral ribs arranged along the axial direction. Several weight-reducing holes are provided on the spiral ribs of the wheel plate. Multiple radially arranged channel steels are arranged around the surface of the wheel plate away from the winding drum. The wheel plate and the winding drum are connected by a tenon and mortise structure and locked by a first bolt.

[0007] The working principle of this scheme is as follows: the spiral ribs are set along the axial direction to connect the core tube and the winding drum, forming an internal support skeleton, which enhances the overall torsional and compressive strength, forms a continuous force transmission path, and converts the radial pressure generated by the winding tension into the axial component force of the spiral ribs, which is then evenly transmitted to the overall structure through shearing action to avoid stress concentration.

[0008] Weight-reducing holes are opened on the spiral ribs, reducing material usage without significantly weakening structural strength; radially arranged channel steels are attached to the surface of the wheel plate as reinforcing ribs, distributing load and improving the bending stiffness of the wheel plate; the tenon and mortise structure provides mechanical interlocking, ensuring precise alignment and connection stability between the wheel plate and the winding drum, while the first bolt applies preload to prevent loosening of the connection.

[0009] The beneficial technical effects of this solution are: it achieves a balance between lightweight and high strength; the spiral ribs and channel steel significantly improve the load-bearing capacity and deformation resistance of the I-beam, making it especially suitable for heavy wire winding; the weight-reducing holes reduce the self-weight, thereby reducing transportation costs and drive load; the mortise and tenon structure with bolt locking ensures a firm connection, preventing separation or deformation under high-speed rotation or high tension, and improving the service life and safety of the I-beam.

[0010] Furthermore, the wheel plate includes an inner web and a flange connected to the edge of the inner web and protruding beyond it. A mounting hole for connecting the end of the winding drum is provided in the middle of the inner web. The channel steel connects both the flange and the inner web. The wheel plate consists of an inner web and a flange. The inner web connects to the winding drum, while the flange provides edge support. The mounting hole is used for inserting the end of the winding drum to ensure alignment. The channel steel radially connects the flange and the inner web, transferring the load from the flange to the inner web, forming a continuous support frame. The bridging connection of the channel steel enhances the overall rigidity of the wheel plate, effectively preventing the flange from bulging or twisting under winding tension, thus improving the stability and winding quality of the I-beam wheel.

[0011] Furthermore, the tenon and mortise of the mortise and tenon structure are respectively located on the inner web plate and the winding drum. The tenon (protruding part) is located on the inner web plate, and the mortise (groove part) is located at the end of the winding drum, or vice versa. The tenon and tenon joint achieves the insertion connection between the wheel plate and the winding drum, forming a mechanical interlock. This ensures precise alignment and tight fit between the wheel plate and the winding drum, reducing connection gaps; the mortise and tenon structure shares some of the bending moment and torque, reduces the stress on the bolts, improves the fatigue resistance and reliability of the connection, and prevents displacement under dynamic loads.

[0012] Furthermore, the first bolt connects the tenon and the mortise. The first bolt provides axial preload, eliminating the gap between the tenon and the mortise, forming a rigid connection and avoiding the risk of loosening of a simple mortise and tenon connection under vibration.

[0013] Furthermore, the ends of the core tube and the winding drum are connected to two parallel circular plates that are coaxial with the core tube. The two coaxial circular plates form an end constraint ring, which, by drawing on the stiffness enhancement principle of sandwich structures, limits the radial deformation of the winding drum end through radial support, while providing axial positioning for the core tube and preventing axial movement of the core tube under tension.

[0014] Furthermore, the circular plates are provided with threaded holes, and the corresponding threaded holes on the two circular plates are connected by a second bolt. The second bolt passes through the two circular plates to form an "axial tie rod structure". Through the preload, the circular plates generate radial constraints on the winding drum, similar to the constraint effect of a spiral bar, which transforms the dispersed end load into the axial preload of the overall structure and improves the resistance to instability.

[0015] Furthermore, an annular connecting plate is integrally formed in the middle of the side of the inner web away from the winding drum. The connecting plate is coaxial with the mounting hole and also has threaded holes. The threaded holes on the corresponding circular plate allow the second bolt to be connected to the threaded holes on both the circular plate and the connecting plate simultaneously. The annular connecting plate is integrally formed with the inner web, allowing the wheel plate to directly participate in the axial fastening of the core structure through the second bolt, forming a rigid closed loop among the wheel plate, circular plate, and core tube. The coaxial design of the threaded holes ensures that the preload is evenly transmitted to the wheel plate, avoiding uneven local stress.

[0016] Furthermore, the spiral ribs are welded to the core tube. The welding of the spiral ribs and the core tube forms a "core reinforcing skeleton," and during assembly, the two are assembled as a whole into the winding drum, improving assembly efficiency.

[0017] Furthermore, the spiral rib is welded to the winding drum. Attached Figure Description

[0018] Figure 1 This is a cross-sectional view of the reinforced H-beam wheel of this utility model. Detailed Implementation

[0019] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: 1. winding drum; 2. core tube; 3. spiral rib; 4. rim; 5. inner web plate; 6. channel steel; 7. connecting plate; 8. second bolt; 9. round plate; 10. first bolt; 11. mortise; 12. tenon.

[0020] This embodiment provides a reinforced H-beam wheel, the overall structure of which is as follows: Figure 1 As shown, this I-beam wheel mainly consists of two parts: a cylindrical assembly and a wheel plate assembly.

[0021] The cylindrical assembly is the core load-bearing component of the wound material, comprising a winding drum 1, a core tube 2, and a spiral rib 3 connecting the two. The core tube 2 is coaxially disposed inside the winding drum 1, and the two are fixedly connected by the spiral rib 3 extending axially, forming a reinforced structure with a continuous spiral support skeleton inside. Multiple weight-reducing holes are spaced apart on the spiral rib 3, achieving effective weight reduction while ensuring structural strength. Two circular plates 9, coaxial with the core tube 2, are fixedly connected to both ends of the winding drum 1, and the two circular plates 9 are arranged parallel to each other. Threaded holes are evenly distributed on the circular plates 9, and the two ends of the circular plates 9 are tightened and fixed by second bolts 8 passing through these threaded holes, thereby further enhancing the integrity and rigidity of the end structure.

[0022] The wheel plate assembly is a key component providing lateral support and connecting force transmission, comprising an inner web plate 5 and a rim 4 connected to the outer edge of the inner web plate 5. A mounting hole is provided in the center of the inner web plate 5 to accommodate the end of the winding drum 1. On the side of the wheel plate assembly facing away from the winding drum 1, multiple radially arranged channel steels 6 are arranged in a ring. These channel steels 6 are fixedly connected to both the inner web plate 5 and the rim 4, forming a truss-like reinforcing structure radiating from the center outwards, greatly improving the bending stiffness of the wheel plate. On the side of the wheel plate assembly facing the winding drum 1, a tenon and mortise structure is provided, specifically a tenon 12 on the inner web plate 5 and a mortise 11 corresponding to the end of the winding drum 1. During assembly, the tenon 12 engages with the mortise 11 for precise positioning and mechanical interlocking, and the two are fastened together by a first bolt 10.

[0023] As a preferred connection method, an annular connecting plate 7 is integrally formed in the middle of the side of the inner web plate 5 away from the winding drum 1. The connecting plate 7 is coaxial with the mounting hole. The connecting plate 7 is also provided with threaded holes, and its position corresponds to the threaded holes on the circular plate 9. This allows the second bolt 8 to pass through the threaded holes on the connecting plate 7 while connecting the two circular plates 9 at both ends, thereby tightly connecting the wheel plate assembly and the cylinder assembly into a rigid whole.

[0024] This I-beam reel constructs a continuous spiral support skeleton between the winding drum and the core tube through spiral ribs, which converts radial pressure into axial force and transmits it evenly. Combined with the weight reduction holes on the spiral ribs, it achieves precise weight reduction. The circular plates at both ends are tightened with bolts to form a sandwich constraint, which effectively enhances the end rigidity and overall stability.

[0025] This I-beam wheel constructs a continuous spiral support skeleton between the winding drum 1 and the core tube 2 through the spiral rib 3, which converts the radial pressure into an axial component force and transmits it evenly. Combined with the weight reduction holes on the spiral rib 3, it achieves precise weight reduction. The circular plates 9 at both ends are tightened with bolts to form a sandwich constraint, which effectively enhances the end rigidity and overall stability.

[0026] The wheel plate uses radial channel steel 6 to form a truss support, which efficiently transmits the winding tension to the center; the wheel plate and the winding drum 1 are mechanically interlocked through a mortise and tenon structure, and then reinforced with bolts to ensure a reliable connection. The overall structure significantly reduces its weight while ensuring high strength, meeting the dual requirements of structural strength and lightweight for heavy-duty wire winding.
