Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and more specifically, to a steel coil support device and a container having the same. Background Technology

[0002] In steel coil support devices of relevant technologies, especially for the transportation of hot-rolled steel coils, the design primarily focuses on the stability and secure fixing of the coils. However, most of these devices use separate baffles to restrict the position of the coils and prevent displacement due to vibration or collision during transportation. This design is acceptable at room temperature, but in high-temperature operating environments, workers need to align, install, and disassemble the baffles, significantly increasing the operational difficulty. On the one hand, manual operation under high-temperature conditions increases the health risks for operators; on the other hand, in logistics scenarios requiring frequent operations, the installation and disassembly of the baffles become complex and time-consuming, reducing work efficiency and potentially leading to safety hazards due to improper operation. Therefore, existing steel coil support devices have significant shortcomings in terms of operational convenience and safety when addressing the transportation needs of hot-rolled steel coils, especially in high-temperature environments. Summary of the Invention

[0003] The main objective of this invention is to provide a steel coil support device and a container having the same, in order to solve the problem of difficult operation of the stop in the related art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a steel coil support device is provided, comprising: a mounting base having a receiving space; a fixed limiting mechanism disposed within the receiving space, the fixed limiting mechanism including a first limiting member and a second limiting member, the first limiting member and the second limiting member being disposed opposite to each other and both used to abut against the circumferential surface of the steel coil; a movable limiting mechanism rotatably and movablely disposed between the first limiting member and the second limiting member, the movable limiting mechanism having a stopping state for stopping the end of the steel coil and a yielding state for yielding the steel coil, the movable limiting mechanism switching between the stopping state and the yielding state by rotation, the movable limiting mechanism being movable in the yielding state being movable in the axial direction of the steel coil; and a stopping mechanism disposed on the first limiting member, the stopping mechanism engaging with the movable limiting mechanism when the movable limiting mechanism is in the stopping state to limit the movement of the movable limiting mechanism in the axial direction of the steel coil.

[0005] Furthermore, the steel coil support device also includes a rotating shaft and an anti-rotation mechanism. The rotating shaft is disposed on the first limiting member, and the first end of the movable limiting mechanism is disposed on the rotating shaft and can move along the axial direction of the rotating shaft. The anti-rotation mechanism is disposed between the rotating shaft and the first limiting member. The anti-rotation mechanism has an anti-rotation state that restricts the rotation of the rotating shaft and a release state that releases the rotating shaft. When the anti-rotation mechanism is in the anti-rotation state, it restricts the movable limiting mechanism from switching from the stop state to the avoidance state.

[0006] Furthermore, the anti-rotation mechanism includes a turntable and an anti-rotation rod. The turntable is located at the end of the rotating shaft, and a stop surface is provided in the circumferential direction of the turntable. The anti-rotation rod is movably located on the first limiting member. When the anti-rotation mechanism is in the anti-rotation state, the anti-rotation rod cooperates with the stop surface to restrict the rotation of the turntable. When the anti-rotation mechanism is in the released state, the anti-rotation rod avoids the turntable.

[0007] Furthermore, the movable limiting mechanism includes a sleeve and a stop bar. The stop bar is used to stop the end of the steel coil. The stop bar is connected to the sleeve, and the sleeve is sleeved on the rotating shaft. A synchronous rotation mechanism is provided between the sleeve and the rotating shaft.

[0008] Furthermore, the synchronous rotation mechanism includes a slidingly fitted groove and a rib, one of which is disposed on the rotating shaft, and the other of which is disposed on the inner surface of the sleeve.

[0009] Furthermore, the pivot and stop mechanism are located on top of the first limiting member.

[0010] Furthermore, the stop mechanism includes multiple first limiting plates, which are spaced apart along the axial direction of the steel coil. The first limiting plates are matched with the top end of the stop rod for limiting. When the movable limiting mechanism is in the stop state, the movable limiting mechanism is located between two adjacent first limiting plates.

[0011] Furthermore, the steel coil support device also includes a limiting seat, which is set at the bottom of the mounting base and located between the first limiting member and the second limiting member. The limiting seat has multiple second limiting plates, which are arranged one-to-one with the multiple first limiting plates. The second limiting plates are matched with the bottom end of the stop bar for limiting.

[0012] Furthermore, the first limiting component includes a supporting inclined surface that abuts against the circumferential surface of the steel coil, and the stop bar includes a main rod section. When the movable limiting mechanism is in the stop state, the main rod section and the supporting inclined surface are fitted together.

[0013] According to another aspect of the present invention, a container is provided, including a steel coil support device, wherein the steel coil support device is the steel coil support device described above.

[0014] By applying the technical solution of this invention, the steel coil support device, through the setting of a rotatable and movable movable limiting mechanism, can switch between a stopping state and a yielding state, achieving flexible restriction and yielding of the end of the steel coil. In the yielding state, the movable limiting mechanism moves freely along the axial direction of the steel coil. On the one hand, this facilitates quick loading and unloading of the steel coil, simplifies the operation process, and reduces operational risks. On the other hand, when faced with steel coils of different sizes, the movable limiting mechanism can stop the steel coils of different sizes by moving it. In the stopping state, the movable limiting mechanism, through its limiting cooperation with the stop mechanism set on the first limiting member, restricts the movement of the movable limiting mechanism, thereby restricting the axial movement of the steel coil, ensuring the stability of the steel coil during transportation, preventing axial displacement of the steel coil during transportation, and improving transportation safety. The combination of the movable limiting mechanism and the stop mechanism overcomes the limitations of the difficult operation of traditional fixed stops, achieving efficient and convenient operation, optimizing the user experience of the steel coil support device, and improving logistics efficiency. Therefore, the technical solution of this application can effectively solve the problem of difficult operation of the baffle in the related technology. Attached Figure Description

[0031] like Figures 1 to 5As shown, this application provides a steel coil support device. An embodiment of the steel coil support device includes: a mounting base 10, a fixed limiting mechanism 20, a movable limiting mechanism 30, and a stop mechanism 40. The mounting base 10 has a receiving space 11. The fixed limiting mechanism 20 is disposed within the receiving space 11 and includes a first limiting member 21 and a second limiting member 22. The first limiting member 21 and the second limiting member 22 are disposed opposite to each other and both are used to abut against the circumferential surface of the steel coil 1. The movable limiting mechanism 30 is rotatably and movablely disposed on the first limiting member 21 and the second limiting member 22. Between the limiting members 22, the movable limiting mechanism 30 has a stopping state that stops the end of the steel coil 1 and a yielding state that avoids the steel coil 1. The movable limiting mechanism 30 switches between the stopping state and the yielding state by rotation. When the movable limiting mechanism 30 is in the yielding state, the movable limiting mechanism 30 can move along the axial direction of the steel coil 1. The stopping mechanism 40 is provided on the first limiting member 21. When the movable limiting mechanism 30 is in the stopping state, the stopping mechanism 40 cooperates with the movable limiting mechanism 30 to limit the movement of the movable limiting mechanism 30 along the axial direction of the steel coil 1.

[0032] Applying the technical solution of this embodiment, the steel coil support device, by setting a rotatable and movable movable limiting mechanism 30, can switch between a stopping state and a yielding state, achieving flexible restriction and yielding of the end of the steel coil 1. In the yielding state, the movable limiting mechanism 30 moves freely along the axial direction of the steel coil 1. On the one hand, this facilitates quick loading and unloading of the steel coil 1, simplifies the operation process, and reduces operational risks. On the other hand, when faced with steel coils 1 of different sizes, the movable limiting mechanism 30 can be moved to stop steel coils 1 of different sizes. In the stopping state, the movable limiting mechanism 30 cooperates with the stopping mechanism 40 set on the first limiting member 21 to limit the movement of the movable limiting mechanism 30, thereby limiting the axial movement of the steel coil 1, ensuring the stability of the steel coil 1 during transportation, preventing axial displacement of the steel coil 1 during transportation, and improving transportation safety. By employing the coordination of the movable limiting mechanism 30 and the stop mechanism 40, the limitations of traditional fixed stops in terms of operational difficulty are overcome, achieving efficient and convenient operation, optimizing the user experience of the steel coil support device, and improving logistics efficiency. Therefore, the technical solution of this embodiment can effectively solve the problem of difficult operation of stops in related technologies.

[0033] like Figures 1 to 5As shown, the steel coil support device also includes a rotating shaft 51 and an anti-rotation mechanism 52. The rotating shaft 51 is disposed on the first limiting member 21. The first end of the movable limiting mechanism 30 is disposed on the rotating shaft 51 and can move along the axial direction of the rotating shaft 51. The anti-rotation mechanism 52 is disposed between the rotating shaft 51 and the first limiting member 21. The anti-rotation mechanism 52 has an anti-rotation state that restricts the rotation of the rotating shaft 51 and a release state that releases the rotating shaft 51. When the anti-rotation mechanism 52 is in the anti-rotation state, it restricts the movable limiting mechanism 30 from switching from the stop state to the avoidance state.

[0034] In this embodiment, the steel coil support device integrates a rotating shaft 51 and an anti-rotation mechanism 52. The rotating shaft 51 is firmly mounted on the first limiting member 21, allowing the movable limiting mechanism 30 to rotate around the rotating shaft 51 and move along the axis of the rotating shaft 51. The anti-rotation mechanism 52 is cleverly positioned between the rotating shaft 51 and the first limiting member 21, and has two functional modes: an anti-rotation state and a release state. When the anti-rotation mechanism 52 is in the anti-rotation state, it effectively prevents the rotation of the rotating shaft 51, thereby limiting the movable limiting mechanism 30 from the stop state to the avoidance state, ensuring the stability of the steel coil 1 during transportation. This design not only simplifies the operation process and improves safety, but also enhances the adaptability of the device. Especially in high-temperature environments, it avoids frequent manual intervention, reduces operational risks, and makes the entire device more stable and reliable, better able to withstand the dynamic loads of the steel coil 1 during transportation. Of course, if the anti-rotation mechanism 52 is released and the shaft 51 is in the released state, it can rotate freely, allowing the movable limit mechanism 30 to flexibly adjust its position in the avoidance state, thus facilitating the loading and unloading of the steel coil 1. This integrated design significantly optimizes the operating experience and improves work efficiency, making it an ideal solution for handling steel in logistics scenarios.

[0035] like Figures 1 to 5 As shown, the anti-rotation mechanism 52 includes a turntable 521 and an anti-rotation rod 522. The turntable 521 is disposed at the end of the rotating shaft 51. A stop surface 523 is provided in the circumferential direction of the turntable 521. The anti-rotation rod 522 is movably disposed on the first limiting member 21. When the anti-rotation mechanism 52 is in the anti-rotation state, the anti-rotation rod 522 cooperates with the stop surface 523 to restrict the rotation of the turntable 521. When the anti-rotation mechanism 52 is in the released state, the anti-rotation rod 522 avoids the turntable 521.

[0036] In this embodiment, when the anti-rotation mechanism 52 is in the anti-rotation state, the anti-rotation rod 522 cooperates with the stop surface 523 to restrict the rotation of the turntable 521, thereby preventing the movable limiting mechanism 30 from switching from the stop state to the avoidance state. This design ensures the stability of the movable limiting mechanism 30 in the stop state and prevents the failure of the support and positioning of the steel coil 1 due to accidental rotation. When it is necessary to adjust the movable limiting mechanism 30 to the avoidance state, the anti-rotation rod 522 can move to the position of the avoidance turntable 521, releasing the restriction on the turntable 521, thereby allowing the rotating shaft 51 to drive the movable limiting mechanism 30 to perform the required rotation. This anti-rotation and release switching mechanism not only ensures the safe operation of the equipment, but also facilitates the operator to flexibly adjust the state of the movable limiting mechanism 30 according to the actual situation, enhancing the practicality and safety of the steel coil support device. In subsequent operations, the movable limiting mechanism 30 can move along the axial direction of the rotating shaft 51 as needed to achieve adaptive support for steel coils 1 of different sizes. At the same time, the stop mechanism 40 can restrict the movement of the movable limiting mechanism 30 along the axial direction of the steel coil 1 when the movable limiting mechanism 30 is in the stop state, thus ensuring the stability and safety of the steel coil 1 during transportation.

[0037] like Figures 1 to 5 As shown, the movable limiting mechanism 30 includes a sleeve 31 and a stop bar 32. The stop bar 32 is used to stop the end of the steel coil 1. The stop bar 32 is connected to the sleeve 31. The sleeve 31 is sleeved on the rotating shaft 51. A synchronous rotation mechanism 53 is provided between the sleeve 31 and the rotating shaft 51.

[0038] In this embodiment, the sleeve 31 is fitted onto the rotating shaft 51. This structure allows the stop lever 32 to rotate around the rotating shaft 51 and move axially along it. A synchronous rotation mechanism 53 is provided between the sleeve 31 and the rotating shaft 51, ensuring that the stop lever 32 moves synchronously with the rotating shaft 51 during rotation. This makes the operation of the stop lever 32 more stable and precise when switching from an avoidance state to a stop state or vice versa, avoiding jamming, slippage, or instability caused by asynchrony. This improves the efficiency and safety of the steel coil 1 positioning and release process.

[0039] Through this design, the movable limiting mechanism 30 can flexibly switch between a stop state and a clearance state. When loading or unloading steel coil 1 is required, the stop bar 32 can rotate to the clearance state and move along the axial direction of the rotating shaft 51 to facilitate the entry and exit of steel coil 1. During transportation, the stop bar 32 can rotate to the stop state and be positioned in cooperation with the stop mechanism 40 to prevent the steel coil 1 from shifting within the container, ensuring transportation safety. The synchronous rotation mechanism 53 further enhances the reliability of the movable limiting mechanism 30, enabling it to smoothly complete the transition between different states and meeting the needs of efficient logistics. In addition, the movable limiting mechanism 30's ability to move along the axial direction of the steel coil 1 also makes the device more adaptable and flexible when handling steel coils 1 of different sizes. This design not only simplifies the operation process and reduces the workload and risks for operators in high-temperature working environments, but also improves the efficiency and safety of the entire logistics system.

[0040] like Figures 1 to 5 As shown, the synchronous rotation mechanism 53 includes a slidingly fitted groove 531 and a rib 532. One of the groove 531 and the rib 532 is disposed on the rotating shaft 51, and the other of the groove 531 and the rib 532 is disposed on the inner surface of the sleeve 31.

[0041] In this embodiment, the synchronous rotation mechanism 53 includes a slidingly fitted groove 531 and a raised rib 532, one of which is disposed on the rotating shaft 51 and the other on the inner surface of the sleeve 31. This design allows the movable limiting mechanism 30 to rotate synchronously with the rotating shaft 51, thereby ensuring a smooth switching between the movable limiting mechanism 30 and the avoidance state. Through the mutual cooperation of the groove 531 and the raised rib 532, not only is a reliable connection between the rotating shaft 51 and the sleeve 31 achieved, but the movable limiting mechanism 30 also remains stable during rotation, avoiding swaying or offset caused by rotation, and ensuring the safety and efficiency of the steel coil support device during operation. In addition, the sliding fit design allows the movable limiting mechanism 30 to move freely within a certain range, so as to adjust its position and better adapt to steel coils 1 of different diameters or lengths, enhancing the versatility and flexibility of the device. With the above structure, the switching between the movable limiting mechanism 30 and the avoidance state is smoother and easier to operate, greatly improving the convenience and safety of the steel coil support device.

[0042] like Figures 1 to 5 As shown, the rotating shaft 51 and the stop mechanism 40 are located on top of the first limiting member 21. Compared to other locations on the first limiting member 21, this design allows for more space between the first limiting member 21 and the second limiting member 22 to accommodate the steel coil 1, representing an optimized layout for the rotating shaft 51 and the stop mechanism 40.

[0043] The stop mechanism 40 includes a plurality of first limiting plates 41, which are spaced apart along the axial direction of the steel coil 1. The first limiting plates 41 are engaged with the top end of the stop rod 32 for limiting. When the movable limiting mechanism 30 is in the stop state, the movable limiting mechanism 30 is located between two adjacent first limiting plates 41.

[0044] In this embodiment, this design uses the first limiting plate 41 to limit the top of the stop bar 32, effectively preventing the movable limiting mechanism 30 from moving along the axial direction of the steel coil 1 when it is stopped. This ensures the stability of the steel coil 1 during transportation and avoids safety risks caused by the movement of the limiting mechanism. Simultaneously, the spaced arrangement of the first limiting plate 41 allows for adjustment of the position of the movable limiting mechanism 30 according to different specifications of steel coils 1, improving the adaptability of the steel coil support device to various sizes of steel coils 1, achieving more flexible loading configurations, and improving transportation efficiency.

[0045] like Figures 1 to 5 As shown, the steel coil support device also includes a limiting seat 54, which is located at the bottom of the mounting base 10 and between the first limiting member 21 and the second limiting member 22. The limiting seat 54 has a plurality of second limiting plates 55, which are arranged one-to-one with the plurality of first limiting plates 41. The second limiting plates 55 are matched with the bottom end of the stop bar 32 for limiting.

[0046] In this embodiment, this design limits the movable limiting mechanism 30 from the bottom, forming a double limiting mechanism with the stop mechanism 40. This ensures that the stop rod 32 stably and reliably fixes the end of the steel coil 1 in the stop state, preventing displacement of the steel coil 1 due to vibration during transportation, thereby improving the safety and stability of the entire steel coil support device. Cooperating with the first limiting plate 41 at the top, the second limiting plate 55 of the limiting seat 54 can more comprehensively control the position of the stop rod 32, making the axial fixation of the steel coil 1 more secure and reducing risks during transportation.

[0047] like Figures 1 to 5 As shown, the first limiting member 21 includes a supporting inclined surface 211, which abuts against the circumferential surface of the steel coil 1. The stop bar 32 includes a main rod section 321. When the movable limiting mechanism 30 is in the stop state, the main rod section 321 and the supporting inclined surface 211 are fitted together.

[0048] In this embodiment, this design ensures that when the movable limiting mechanism 30 locks the end of the steel coil 1, the main rod section 321 of the stop bar 32 is in close contact with the supporting inclined surface 211, thereby providing a more stable supporting force, effectively preventing the steel coil 1 from shifting during transportation, enhancing transportation safety, and optimizing the layout of the movable limiting mechanism 30. It should be noted that "the main rod section 321 and the supporting inclined surface 211 are in close contact" means that the distance between the main rod section 321 and the supporting inclined surface 211 can be between 0 and 20 mm.

[0049] This application also provides a container, which includes a steel coil support device, wherein the steel coil support device is the aforementioned steel coil support device. The aforementioned steel coil support device effectively solves the problem of difficult operation and use of stoppers in related technologies, and the container with the aforementioned steel coil support device also has the above-mentioned advantages.

[0050] In the description of this invention, it should be understood that "a plurality of" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing the invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this invention. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0051] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0052] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0053] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
