Description

Technical Field

[0001] This utility model relates to the field of galvanized coil maintenance technology, specifically to a collapse handling rack for cold-rolled galvanized steel coils. Background Technology

[0002] During production, cold-rolled galvanized coils are prone to coil collapse defects, where the coil core changes from a perfect circle to an elliptical shape due to factors such as drum precision, coil tension matching, and external conditions. In severe cases, the coil core becomes flattened. This defect is called coil collapse or flattened coil. After collapse, the horizontal diameter of the coil increases, while the vertical diameter decreases. Typically, the inner diameter of a galvanized coil is 507mm, and the expansion and contraction range of the uncoiler drum in a rework unit is 457.7mm-520mm. Rework is difficult for coils with a vertical inner diameter of 400mm-460mm, and they can only be downgraded.

[0003] Collapse defects in galvanized steel coils have varying degrees of impact on subsequent operations. For example, in processing, the uncoiling strip is prone to deviation, and changes in coil size lead to decreased processing accuracy, uneven slitting, and other problems, requiring frequent machine stops for adjustments and severely slowing down processing efficiency. In storage and transportation, collapsed coils cannot be stacked tightly, resulting in low utilization of storage space. They are also prone to rolling displacement during transportation, which can damage transport equipment, exacerbate coil damage, and even cause breakage. Therefore, collapse defects in steel coils have a significant impact on subsequent processing, storage, and transportation, necessitating a device to repair collapsed galvanized steel coils. Utility Model Content

[0004] The purpose of this utility model is to provide a collapse handling rack for cold-rolled galvanized steel coils to solve the problem of collapse defects in galvanized steel coils, which affect subsequent processing, storage and transportation.

[0005] To achieve the above objectives, the basic solution provided by this utility model is as follows: a collapse handling rack for cold-rolled galvanized steel coils, including a base, a plurality of supports on the base, an arc-shaped plate on the plurality of supports, a plurality of support plates between the plurality of supports, a movable component movably passing through the plurality of support plates, a baffle connected to one end of the plurality of movable components, and the baffles movably passing through the arc-shaped plate.

[0006] The principle and beneficial effects of this utility model are as follows: by adjusting the diameter of the movable baffle of the movable component, it is ensured that the steel coil with collapse defects is evenly stressed after being placed in the device. Under the influence of its own weight, the outer diameter of the steel coil will be filled and pressed against the inner wall of the arc plate. At the same time, the reaction force of the inner wall of the arc plate acts as a driving force on the outer diameter of the steel coil and is then transmitted to the steel coil. Under the action of the reaction force, the collapse of the inner diameter of the steel coil will become an elliptical shape or even a circle, which facilitates the restoration of the shape of the steel coil.

[0007] Option 2, a preferred embodiment of the basic option, includes a moving component comprising a push rod fixedly connected to a baffle. The push rod movably passes through a support plate and has a nut positioned between the support plate and the baffle. Pushing or pulling the push rod moves the baffle back and forth. Once the baffle is in the desired position, the nut is rotated to the support plate. The action and reaction forces of the nut and the support plate limit the push rod, thus allowing the baffle to better constrain the position of the steel coil.

[0008] Option 3, a preferred option of the basic scheme, involves a movable component including a sleeve fixedly connected to a baffle. A screw is threaded into the sleeve, and the screw abuts against a support plate. Another method for moving the baffle involves first pushing the baffle forward to a suitable position, then rotating the screw to unscrew it from the sleeve until the end of the screw rests against the support plate again.

[0009] Option 4, a preferred option of the basic scheme, features a limiting component on the curved plate to restrict the position of the steel coil. This limiting component is detachably connected to the curved plate. The limiting component restricts the forward and backward position of the steel coil, reducing the risk of the coil slipping off during the uncoiling process.

[0010] Option 5, a preferred option to Option 2, features a non-slip handle at the end of the push rod. This non-slip handle prevents the push rod from slipping during movement, saving time and increasing work efficiency.

[0011] Option 6, a preferred option of Option 4, includes two limiting rods. The curved plate has several grooves, and the two limiting rods engage with two parallel grooves respectively. The two limiting rods confine the steel coil within a suitable width. The locking mechanism allows for easy removal of the coil when the limiting rods are not needed, making the operation simple, convenient, and quick. Attached Figure Description

[0019] Example

[0020] The basic implementation examples are as follows: Figure 1 , 2 As shown in Figure 4: A coil collapse handling rack for cold-rolled galvanized steel coils includes a base 1, a plurality of supports 2 on the base 1, an arc-shaped plate 3 on the supports 2, a plurality of support plates 4 between the supports 2, a movable component 5 on each support plate 4, a baffle 6 connected to one end of each movable component 5, a top rod 501 fixedly connected to the baffle 6, the top rod 501 movably passing through the support plate 4, an anti-slip handle 8 at the end of the top rod 501, a nut 502 threadedly connected to the top rod 501, the nut 502 located between the support plate 4 and the baffle 6, a plurality of baffles 6 movably passing through the arc plate 3, a limiting component for limiting the position of the steel coil on the arc plate 3, the limiting component being detachably connected to the arc plate 3, the limiting component including two limiting rods 9, a plurality of grooves 7 on the arc plate 3, the two limiting rods 9 respectively engaging with two parallel grooves 7.

[0021] The implementation method of this embodiment is as follows:

[0022] When repairing a steel coil with a collapse defect, the collapsed steel coil is first placed on this device, so that the outer surface of the steel coil is in contact with the inner wall of the arc plate 3. The steel coil's own weight exerts a force on the arc plate 3, and the arc plate 3's own hardness exerts a reaction force on the steel coil. According to the width of the steel coil, two limiting rods 9 are placed in the corresponding grooves 7, respectively, limiting the position of the steel coil between the two limiting rods 9. Next, according to the outer diameter of the steel coil, the top rod 501 is pushed to adjust the position of the baffle 6. After the baffle 6 reaches the appropriate position, the nut 502 is rotated to make it fit and abut against the support plate 4, thereby limiting the position of the baffle 6. When all the baffles 6 are adjusted to the appropriate position, the inner diameter of the collapsed steel coil is lifted with the help of a jack. This device limits the outer diameter of the steel coil, and finally realizes the restoration of the collapsed steel coil.

[0023] Example 2

[0024] The basic implementation examples are as follows: Figure 1 , 3 As shown in Figure 5: The difference from Embodiment 1 is that the moving component 5 includes a sleeve 503, which is fixedly connected to the baffle 6. A screw 504 is threaded into the sleeve 503, and the screw 504 abuts against the support plate 4.

[0025] The implementation method of this embodiment is as follows:

[0026] When moving the baffle 6, push the sleeve 503 inward. The sleeve 503 will drive the baffle 6 and the screw 504 to move together. After the baffle 6 is adjusted to the appropriate position, rotate the screw 504 to unscrew it. At the same time, hold the sleeve 503 to prevent it from being rotated by the screw 504. When the end of the screw 504 abuts against the support plate 4, the position of the baffle 6 can be limited.
