Description

Technical Field

[0001] This invention relates to the field of steel coil protection technology, and in particular to a quick-release steel coil protective cover. Background Technology

[0002] Cold rolling: Using hot-rolled steel coils as raw materials, after pickling to remove oxide scale, the coils are continuously cold-rolled. The finished product is a hard-rolled coil. Due to the work hardening caused by continuous cold deformation, the strength and hardness of the hard-rolled coil increase while its toughness and plasticity decrease. Therefore, its stamping performance will deteriorate, and it can only be used for parts with simple deformation. After the cold rolling mill produces the steel coils, it will be packaged for rust prevention.

[0003] Currently, the main technologies used in the packaging process of steel coils are steel coil packaging machines and protective packaging cloths. The protective packaging cloths are installed inside the steel coil packaging machine. When it is necessary to package the steel coil, the protective packaging cloths sprayed out from the steel coil packaging machine cooperate with the outer wall of the rotating steel coil to achieve rust prevention packaging of the steel coil.

[0004] However, in the current technology, the temperature difference between day and night is large in the Jiangnan region, and the air is humid during the rainy season. At this time, when the capacity of cold rolling mills expands and the production efficiency of steel coils exceeds the packaging efficiency, steel coils that cannot be packaged in time will be piled up inside the factory. Under the influence of the humid environment, steel coils that have not been promptly packaged for rust prevention are very prone to developing rust spots on both sides, which will have a certain adverse effect on the subsequent sales of the steel coils.

[0005] Therefore, a quick-release steel coil protective cover is proposed to address the above problems. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the problems existing in the prior art.

[0007] To solve the above-mentioned technical problems, the present invention provides a quick-release steel coil protective cover, including a steel coil body, with protective mechanisms provided at both ends of the steel coil body. The protective mechanism includes a first central circular plate, with a circular protective cloth fixed to the circumferential sidewall of the first central circular plate. The rear wall of the circular protective cloth can contact the steel coil body. A central rotating shaft is fixed at the front center of the first central circular plate, and a second central circular plate is fixed to one end of the central rotating shaft. A protective component is provided between the second central circular plate and the first central circular plate. A plurality of protective components are provided, and the plurality of protective components are arranged in an array along the circumferential direction of the outer wall of the central rotating shaft. The protective component includes an L-shaped assembly plate and an assembly block.

[0008] In one embodiment of the present invention, a fitting ring is fixed to the bottom surface of the assembly block by a bracket, and the inner wall of the through hole of the fitting ring is engaged with the outer wall of the central rotating shaft. A first linkage straight plate is vertically fixed to the top surface of the assembly block, and a first slider track is provided on both the front and rear surfaces of the first linkage straight plate.

[0009] In one embodiment of the present invention, one end of the outer wall of the L-shaped assembly plate can contact the outer wall of the steel coil body, and the bottom surface of the other end of the L-shaped assembly plate is vertically fixed with a second linkage straight plate, and the front and rear surfaces of the second linkage straight plate are provided with second slider tracks.

[0010] In one embodiment of the present invention, a first linkage block is fixed to one end of the first linkage plate, and a first engaging block is fixed to one side of the first linkage block near the front and rear edges. The outer wall of the first engaging block engages with the inner wall of the second slider track.

[0011] In one embodiment of the present invention, a second linkage block is fixed at one end of the second linkage plate, and a second engaging block is fixed on one side of the second linkage block near the front and rear edges. The outer wall of the second engaging block engages with the inner wall of the first slider track.

[0012] In one embodiment of the present invention, a first elastic telescopic rod is fixed between the adjacent sidewalls of the first linkage block and the second linkage block.

[0013] In one embodiment of the present invention, a connecting hook is fixed to the rear wall of the first central circular plate, and a pull handle is fixed to the center of the front wall of the second central circular plate.

[0014] In one embodiment of the present invention, a second elastic telescopic rod is provided inside the hollow channel of the steel coil body.

[0015] In one embodiment of the present invention, both ends of the second elastic telescopic rod are fixed with connecting rings by short rods, and the connecting rings can be sleeved with the connecting hooks.

[0016] In one embodiment of the present invention, a fan-shaped protective cloth is provided between the adjacent sidewalls of two adjacent protective components, and magnetic strips are fixed on both sides of the fan-shaped protective cloth, the magnetic strips being magnetically attracted to the adjacent sidewalls of the two adjacent protective components.

[0017] The technical solution of the present invention has the following advantages compared with the prior art:

[0018] 1. The circular protective cloth of the present invention is installed between the side walls of the first central circular plate. The contact between the circular protective cloth and the two ends of the steel coil body can achieve initial coverage of the steel coil body. The fan-shaped protective cloth achieves the sealing of the gap between the protective components through the magnetic attraction between the magnetic strip and the side wall of the protective component, and cooperates with the circular protective cloth to protect the two ends of the steel coil body. The cooperation between the protective mechanisms at both ends of the steel coil body can seal the inner diameter of the steel coil body and the steel coil layers at both ends, reducing the possibility of humid air entering the interior of the steel coil and causing corrosion. This allows the steel coil body that cannot be packaged in time to be protected by the protective mechanism, increasing the waiting time for packaging the steel coil body.

[0019] 2. Under the elastic contraction force of the first elastic telescopic rod, after the protective component opens on the outer wall of the steel coil body, each L-shaped assembly plate can tighten towards the direction of the central pivot, realizing the mutual contact between the protective component and the outer walls of both ends of the steel coil body. Moreover, the L-shaped assembly plates and assembly blocks can be pulled out within a certain range, allowing the protective mechanism to adapt to the changes in the winding thickness of the steel coil body within a certain range. After the protective mechanism is installed at both ends of the steel coil body, the interlocking between the connecting ring and the connecting hook on the second elastic telescopic rod provides elastic contraction force for the protective mechanism to move closer to each other, increasing the installation stability of the protective mechanism.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0030] Please see Figures 1-7 As shown, a quick-release steel coil protective cover includes a steel coil body 1. Protective mechanisms 2 are provided at both ends of the steel coil body 1. Each protective mechanism 2 includes a first central circular plate 21. A circular protective cloth 211 is fixed to the circumferential sidewall of the first central circular plate 21. The rear wall of the circular protective cloth 211 can contact the steel coil body 1. A central rotating shaft 22 is fixed at the front center of the first central circular plate 21. A second central circular plate 23 is fixed to one end of the central rotating shaft 22. A protective component 3 is provided between the second central circular plate 23 and the first central circular plate 21. Multiple protective components 3 are arranged in an array along the circumferential direction of the outer wall of the central rotating shaft 22. Each protective component 3 includes an L-shaped assembly plate 31 and an assembly block 32.

[0031] During operation, to address the issue of rust spots easily appearing on both sides of steel coils that are not promptly packaged for rust prevention under humid conditions, protective mechanisms 2 are installed at both ends of the steel coil body 1. The cooperation between these protective mechanisms 2 seals the inner diameter of the steel coil body 1 and the steel coil layers at both ends, reducing the possibility of humid air entering the steel coil and causing corrosion. This protects the steel coil body 1 from timely packaging, extending the waiting time for packaging. A central rotating shaft 22 connects the first central circular plate 21 and the second central circular plate 23. The first central circular plate 21, the central rotating shaft 22, and the second central circular plate 23 serve as the central support structure for the protective mechanism 2, supporting the installation of the protective component 3. A circular protective cloth 211 is installed between the side walls of the first central circular plate 21. The contact between the first central circular plate 21 and both ends of the steel coil body 1 provides initial coverage. The protective component 3 cooperates with the outer walls at both ends of the steel coil body 1 to achieve complete coverage and protection.

[0032] Furthermore, such as Figure 4 , Figure 5 and Figure 6 As shown, the bottom surface of the assembly block 32 is fixed with a fitting ring 321 by a bracket. The inner wall of the through hole of the fitting ring 321 is engaged with the outer wall of the central rotating shaft 22. The top surface of the assembly block 32 is vertically fixed with a first linkage straight plate 322. The front and rear surfaces of the first linkage straight plate 322 are provided with first slider tracks 323.

[0033] During operation, the assembly block 32 is installed on the mounting ring 321 via the bracket. The mounting ring 321 can engage with the outer wall of the central rotating shaft 22, enabling the assembly block 32 to be linked with the central rotating shaft 22. This also allows different assembly blocks 32 to be adjusted relative to each other within a certain range, thus achieving the purpose of selecting the protective component 3. Furthermore, the mounting ring 321 connected to different assembly blocks 32 does not overlap with the bottom projection position of the assembly block 32. This ensures that different assembly blocks 32 will not experience rotational obstruction within a certain range after being linked with the central rotating shaft 22 via the mounting ring 321, increasing the rationality of the device structure. The first linkage straight plate 322 is installed on the top surface of the assembly block 32. The first linkage straight plate 322 achieves the mutual linkage between the assembly block 32 and the parts belonging to the L-shaped assembly plate 31 through the opening of the first slider rail 323.

[0034] Furthermore, such as Figure 5 , Figure 6 and Figure 7As shown, one end of the outer wall of the L-shaped assembly plate 31 can contact the outer wall of the steel coil body 1, and the bottom surface of the other end of the L-shaped assembly plate 31 is vertically fixed with a second linkage straight plate 311. The front and rear surfaces of the second linkage straight plate 311 are provided with second slider rails 312.

[0035] During operation, the L-shaped assembly plate 31 is the structure that directly contacts the steel coil body 1 as described in the protective component 3. The linkage between the steel coil body 1 and the protective component 3 is achieved by the mutual contact between the long handle sidewalls of different L-shaped assembly plates 31 and the outer wall of the steel coil body 1 at different positions. The second linkage straight plate 311 is installed on the bottom surface of the short handle of the L-shaped assembly plate 31. The second linkage straight plate 311 and the second slider track 312 opened on it are the structure for the L-shaped assembly plate 31 and the parts belonging to the assembly block 32 to be linked together.

[0036] Furthermore, such as Figure 5 , Figure 6 and Figure 7 As shown, a first linkage block 324 is fixed to one end of the first linkage plate 322, and a first engaging block 325 is fixed to one side of the first linkage block 324 near the front and rear edges. The outer wall of the first engaging block 325 engages with the inner wall of the second slider track 312.

[0037] During operation, the first linkage block 324 is installed at one end of the first linkage straight plate 322. The first linkage block 324, as the end point of the first linkage straight plate 322, achieves linkage between the L-shaped assembly plate 31 and the assembly block 32 through the mutual engagement between the outer wall of the first engaging block 325 and the inner wall of the second slider track 312. The mutual engagement of the locking grooves between the first engaging block 325 and the second slider track 312 allows the relative distance between the L-shaped assembly plate 31 and the assembly block 32 to be controlled within a certain range by pulling up and down.

[0038] Furthermore, such as Figure 5 , Figure 6 and Figure 7 As shown, a second linkage block 313 is fixed to one end of the second linkage plate 311, and a second engaging block 314 is fixed to one side of the second linkage block 313 near the front and rear edges. The outer wall of the second engaging block 314 engages with the inner wall of the first slider track 323.

[0039] During operation, the second linkage block 313 is fixed at one end of the second linkage straight plate 311 as the end point of the second linkage straight plate 311. The second linkage block 313 achieves linkage between the assembly block 32 and the L-shaped assembly plate 31 by engaging with the inner wall of the first slider track 323 through the second engaging block 314. Similarly, the engaging method between the locking grooves of the second engaging block 314 and the first slider track 323 will not affect the mutual pulling between the L-shaped assembly plate 31 and the assembly block 32. The mutual engaging action of the locking grooves of the first engaging block 325 and the second slider track 312 with the locking grooves of the second engaging block 314 and the first slider track 323 can increase the structural stability during the pulling process of the L-shaped assembly plate 31 and the assembly block 32.

[0040] Furthermore, such as Figure 6 and Figure 7 As shown, a first elastic telescopic rod 33 is fixed between the adjacent side walls of the first linkage block 324 and the second linkage block 313.

[0041] During operation, the first elastic telescopic rod 33 is installed between the adjacent side walls of the first linkage block 324 and the second linkage block 313. Due to the elastic contraction characteristic of the first elastic telescopic rod 33, the L-shaped assembly plate 31 and the assembly block 32 tend to move closer to each other under the elastic contraction force of the first elastic telescopic rod 33. The assembly block 32 cooperates with the central rotating shaft 22 through the fitting ring 321, and the L-shaped assembly plate 31 cooperates with the outer wall of the steel coil body 1. Thus, under the elastic contraction force of the first elastic telescopic rod 33, after the protective component 3 opens on the outer wall of the steel coil body 1, each L-shaped assembly plate 31 can tighten in the direction of the central rotating shaft 22, realizing the mutual contact between the protective component 3 and the outer walls of both ends of the steel coil body 1. Furthermore, the L-shaped assembly plate 31 and the assembly block 32 can be pulled out within a certain range, allowing the protective mechanism 2 to adapt to the changes in the winding thickness of the steel coil body 1 within a certain range, thereby increasing the application range of the protective mechanism 2 and increasing the rationality of the device structure.

[0042] Furthermore, such as Figure 3 and Figure 4 As shown, a connecting hook 4 is fixed to the rear wall of the first central circular plate 21, and a pull handle 231 is fixed to the center of the front wall of the second central circular plate 23.

[0043] During operation, the connecting hook 4 is an auxiliary structure fixed to the outer wall of the first central circular plate 21 to connect the protective mechanisms 2 at both ends of the steel coil body 1. The pull handle 231 is fixed to the front surface of the second central circular plate 23, so that the protective mechanism 2 can be pulled out and controlled by the pull handle 231.

[0044] Furthermore, such as Figure 1 and Figure 3As shown, a second elastic telescopic rod 5 is provided inside the hollow channel of the steel coil body 1;

[0045] During operation, the second elastic telescopic rod 5 is installed inside the steel coil body 1, and the second elastic telescopic rod 5 enables the mutual linkage between the protective mechanisms 2 at both ends of the steel coil body 1.

[0046] Furthermore, such as Figure 1 and Figure 3 As shown, both ends of the second elastic telescopic rod 5 are fixed with connecting rings 51 by short rods, and the connecting rings 51 can be sleeved with the connecting hooks 4.

[0047] During operation, connecting rings 51 are installed at both ends of the second elastic telescopic rod 5. The second elastic telescopic rod 5 achieves linkage between the two end protection mechanisms 2 through the interlocking of the connecting rings 51 at both ends with the connecting hooks 4. The second elastic telescopic rod 5 itself has the characteristic of elastic contraction, so that after the second elastic telescopic rod 5 is connected to the two connecting hooks 4 through the connecting rings 51, the two connecting hooks 4 have a tendency to move closer to each other under the elastic contraction force of the second elastic telescopic rod 5. Thus, after the protection mechanism 2 is installed at both ends of the steel coil body 1, the interlocking of the connecting rings 51 and the connecting hooks 4 on the second elastic telescopic rod 5 can provide elastic contraction force for the protection mechanism 2 to move closer to each other, increasing the installation stability of the protection mechanism 2 and increasing the rationality of the device structure. The elastic contraction characteristic of the second elastic telescopic rod 5 itself allows the second elastic telescopic rod 5 to function when the relative length of the steel coil body 1 is within a certain range.

[0048] Furthermore, such as Figure 1 and Figure 3 As shown, a fan-shaped protective cloth 6 is provided between the adjacent sidewalls of two adjacent protective components 3. Magnetic strips 61 are fixed on both sides of the fan-shaped protective cloth 6, and the magnetic strips 6 can magnetically attract the adjacent sidewalls of the two adjacent protective components 3.

[0049] During operation, the fan-shaped protective cloth 6 is installed between adjacent protective components 3. The fan-shaped protective cloth 6 achieves the sealing of the gap between the protective components 3 through the magnetic attraction between the magnetic strip 61 and the side wall of the protective component 3, and cooperates with the circular protective cloth 211 to protect both ends of the steel coil body 1.

[0050] Working Principle: To address the problem of rust spots easily appearing on both sides of steel coils that are not promptly protected against rust in humid environments, the inner diameter and both ends of the steel coil body 1 are sealed by the cooperation of the protective mechanisms 2 at both ends of the steel coil body 1. A central rotating shaft 22 connects a first central circular plate 21 and a second central circular plate 23. A circular protective cloth 211 is installed between the side walls of the first central circular plate 21. The assembly block 32 is installed on the mounting ring 321 via a bracket. The mounting ring 321 can engage with the outer wall of the central rotating shaft 22. The first linkage straight plate 322 achieves the interaction between the assembly block 32 and the parts belonging to the L-shaped assembly plate 31 through the opening of the first slider track 323. The linkage mechanism involves a second linkage plate 311 mounted on the bottom surface of the short handle of the L-shaped assembly plate 31, and a first linkage block 324 mounted on one end of the first linkage plate 322. The second linkage block 313 achieves linkage between the assembly block 32 and the L-shaped assembly plate 31 through mutual engagement between the second engaging block 314 and the inner wall of the first slider track 323. Similarly, the mutual engagement of the locking grooves between the second engaging block 314 and the first slider track 323 does not affect the mutual pulling and pulling between the L-shaped assembly plate 31 and the assembly block 32. The mutual engagement of the locking grooves between the first engaging block 325 and the second slider track 312, and between the second engaging block 314 and the first slider track 323, increases the linkage between the L-shaped assembly plate 31 and the assembly block 32. The structural stability of block 32 during the pulling process is achieved through the elastic contraction characteristic of the first elastic telescopic rod 33. This causes the L-shaped assembly plate 31 and assembly block 32 to tend to move closer to each other under the elastic contraction force of the first elastic telescopic rod 33. The assembly block 32 cooperates with the central rotating shaft 22 through the fitting ring 321, and the L-shaped assembly plate 31 cooperates with the outer wall of the steel coil body 1. This allows each L-shaped assembly plate 31 to tighten towards the central rotating shaft 22 after the protective component 3 opens to the outer wall of the steel coil body 1 under the elastic contraction force of the first elastic telescopic rod 33, thus achieving mutual adhesion between the protective component 3 and the outer walls at both ends of the steel coil body 1. The pull handle 231 is fixed to the second central circular plate 23. The front surface allows the protective mechanism 2 to be pulled out and controlled via the pull handle 231. The second elastic telescopic rod 5 is installed inside the steel coil body 1. The second elastic telescopic rod 5 enables the mutual linkage between the protective mechanisms 2 at both ends of the steel coil body 1. Connecting rings 51 are installed at both ends of the second elastic telescopic rod 5. The second elastic telescopic rod 5 achieves the linkage between the protective mechanisms 2 at both ends through the interlocking of the connecting rings 51 at both ends with the connecting hooks 4. After the second elastic telescopic rod 5 is interconnected with the two connecting hooks 4 through the connecting rings 51, the two connecting hooks 4 can move closer to each other under the elastic contraction force of the second elastic telescopic rod 5. The fan-shaped protective cloth 6 is installed between adjacent protective components 3.The fan-shaped protective fabric 6 achieves sealing of the gaps between the protective components 3 through magnetic attraction between the magnetic strip 61 and the side wall of the protective component 3.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
