Description

Technical Field

[0001] This utility model relates to the technical field of lifting tools, and in particular to a lifting tool for annealing copper alloy wire coils. Background Technology

[0002] Annealing is a crucial step in the processing of copper alloy wire coils, aiming to improve the material's mechanical properties and internal structure through high-temperature treatment. However, in practice, if the coil is placed directly on the trolley for annealing, the high temperature can easily cause adhesion damage at the contact point between the coil and the trolley, often reaching a depth of 100mm, severely impacting the yield. To address this issue, technicians typically employ a suspended annealing method, suspending the coil on the trolley to avoid direct contact.

[0003] Although suspended annealing can effectively reduce adhesion damage, existing suspended annealing methods still have many shortcomings. For example, the inner diameter of the coil is inconsistent when it is rolled up, requiring the fabrication of lifting fixtures of different sizes to accommodate it. This is especially true for special coils such as copper alloy reinforcing bars extruded from copper alloy ingots, which are heavy and have high requirements for annealing quality. Therefore, a solution with a simple structure that can accommodate coils of different inner diameters and is easy to lift is needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a lifting tool for annealing copper alloy wire coils, which solves the problems mentioned in the background section.

[0005] The technical solution of this utility model is as follows:

[0006] A lifting device for annealing copper alloy wire coils includes a connecting plate. A lifting ring is provided at the upper end of the connecting plate. Several inclined rods are evenly distributed along the circumference at the lower end of the connecting plate. J-shaped arc rods are fixedly connected to the ends of the inclined rods. The upper surfaces of the several arc rods are fixedly connected to the same connecting ring. Reinforcing ribs that converge inward and fix each other are provided in the middle of the several inclined rods.

[0007] Furthermore, the combination of several circumferentially arranged inclined rods and arc-shaped rods forms a trumpet-shaped structure, and the diameter of the combination gradually increases from top to bottom.

[0008] Furthermore, the number of the assembly and the reinforcing ribs is six.

[0009] Furthermore, the entire lifting device is made of high-strength metal material.

[0010] Furthermore, the height of the connecting ring is at half the overall height of the lifting device.

[0011] Furthermore, the height of the reinforcing rib is located at half the distance between the lowest point of the connecting ring and the arc-shaped rod.

[0012] Compared with the prior art, the beneficial effects of the technical solution provided by this utility model are as follows:

[0013] 1. By setting up a trumpet-shaped assembly, the diameter of which gradually decreases from top to bottom, the lifting device can be adapted to rolls of material with different inner diameters;

[0014] 2. By setting connecting rings, the overall integrity between curved rods can be enhanced; by setting reinforcing ribs, the deformation resistance of the lifting device can be improved. Attached Figure Description

[0017] 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, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] like Figure 1 As shown, a lifting device for annealing copper alloy wire coils includes a connecting disc 1. The connecting disc 1 is located at the uppermost end of the lifting device and is the core connecting hub and main load-bearing component of the lifting device. It has a disc-shaped structure and is preferably made of high-strength structural steel. A lifting ring 6 is provided at the upper end of the connecting disc 1. The lifting ring 6 is preferably made of alloy steel forging, a high-strength metal material. The lifting ring 6 is welded to the upper end of the connecting disc 1. A threaded hole can also be provided at the upper end of the connecting disc 1 so that the lifting ring 6 is threadedly connected to the connecting disc 1. This threaded connection method not only facilitates the disassembly and replacement of the lifting ring 6, but also allows the installation direction of the lifting device to be adjusted as needed in actual use.

[0019] The lower end of the connecting disc 1 has several inclined rods 2 evenly distributed along the circumference. The ends of the inclined rods 2 are fixedly connected to J-shaped arc rods 3, which are preferably made of high-strength metal materials such as high-quality spring steel. The arc rod 3 includes a semi-circular rod and a vertical rod. The semi-circular rod is used to support the roll material. The curved part of the arc rod 3 (i.e., the semi-circular rod) is made of high-quality spring steel material, which can produce slight deformation when subjected to force. This can better adapt to the slight unevenness of the inner wall of the roll material, increase the contact area, evenly distribute the pressure, reduce damage to the inner wall of the roll material (especially softer copper alloys), and enhance friction to prevent slippage.

[0020] like Figure 1 As shown, a combination of several circumferentially arranged inclined rods 2 and arc-shaped rods 3 forms a trumpet-shaped structure. The diameter of the combination gradually increases from top to bottom, allowing the lifting device to adapt to rolls with different inner diameters, especially exhibiting excellent flexibility when handling rolls with small or large inner diameters. The inclined rods 2 decompose the vertically downward tension, generating a force that tends to extend outwards at the lower end (top of the arc-shaped rod), but this force is constrained by the arc-shaped rods 3 and the connecting ring 5, ultimately maintaining the stable trumpet shape of the entire combination and providing guidance and radial support when inserting the roll. When the lifting device is inserted into the inner hole of the roll, the inner wall of the roll will contact the arc-shaped rod 3 (mainly the semi-circular rod part) on the trumpet-shaped structure at the height that best matches its inner diameter. The weight of the roll acts on the arc-shaped rod 3 through the contact point, and then is transmitted to the inclined rods 2, the connecting plate 1, and the lifting ring 6. The elastic semi-circular rod deforms and fits against the inner wall to provide stable support. The evenly distributed design of the 6 points ensures uniform and balanced load.

[0021] like Figure 1 As shown, the number of the assembly is six; several of the arc-shaped rods 3 are fixedly connected to the upper surface with connecting rings 5, and the number of connecting rings 5 ​​is one. The bottom end of the connecting ring 5 is connected in parallel with each vertical rod, so that the six independent arc-shaped rods 3-slanted rods 2 are firmly connected into a whole at the middle height, preventing the relative displacement of each arc-shaped rod 3 or excessive outward opening / inward contraction during use, which greatly improves the rigidity and stability of the structure; constrains the middle part of the arc-shaped rod vertical rod, which helps to maintain the designed trumpet-shaped structural shape; the design at the half height of the whole helps to balance the center of gravity of the lifting device, making the lifting more stable; at the same time, the rigid ring is set at this key position, which significantly improves the bending and torsional stiffness of the lifting device as a whole.

[0022] like Figure 1As shown, several inclined rods 2 are provided with reinforcing ribs 4 in the middle, which converge inward (pointing to the central axis of the lifting device and converging at a point) and are fixed to each other. The number of reinforcing ribs 4 is six. The core function of the reinforcing ribs 4 is to greatly enhance the ability of the inclined rods 2 to resist bending deformation. When the lifting device is carrying heavy objects (especially rolls with larger inner diameters and support points further out), the inclined rods 2 are subjected to large bending moments. The reinforcing ribs 4 provide additional support, effectively preventing the inclined rods 2 from bending excessively or becoming unstable, making the combination of inclined rods and curved rods more rigid. By connecting the inclined rods 2 and pointing them towards the center, an additional fulcrum or constraint is provided for the inclined rods 2, shortening the effective span of the inclined rods in the direction of force, transforming them from single-span beams into structures with intermediate supports, thereby significantly reducing their bending deformation. The inward convergence design makes full use of the principle of triangular stability.

[0023] like Figure 1 As shown, the height of the reinforcing rib 4 is located at halfway between the lowest point of the connecting ring 5 and the arc-shaped rod 3. This position is usually the area where the bending moment is large after the inclined rod 2 is subjected to force. Setting the reinforcing rib 4 here can most effectively resist deformation and ensure that the lifting device maintains structural stability and shape under heavy load.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
