Description

Technical Field

[0001] This invention belongs to the field of steel production technology, specifically relating to a multi-layer annealing rack for an annealing furnace. Background Technology

[0002] In the field of metal processing and heat treatment, for example, when steel bars are annealed in an annealing furnace, the steel bars are usually wound onto a take-up coil, which is then placed on a dedicated rack and sent into the annealing furnace for processing. How to efficiently and stably store and transport these take-up coils is a crucial factor affecting production efficiency and operational safety.

[0003] Currently, most annealing furnace racks are fixed structures. When heavy winding drums need to be placed on or removed from the rack's storage supports, the production site typically uses hoisting tools (such as overhead cranes) in conjunction with manual labor for loading and unloading operations. Operators need to manually secure the slings or clamps to the winding drum. After it is hoisted into place, they also need to manually adjust the circumferential position of the winding drum to align it with the positioning structure on the storage support before the placement or removal can be completed.

[0004] However, the existing operating methods described above have significant shortcomings. First, the entire loading and unloading process is highly dependent on manual operation, which is not only inefficient but also requires operators to be in close contact with and hold the heavy winding drum, resulting in extremely high labor intensity and safety hazards. Second, the traditional material rack structure is not convenient enough for storing and retrieving the winding drum, lacking an effective quick positioning and fixing mechanism, leading to cumbersome loading and unloading steps. Therefore, this application proposes a multi-layer annealing material rack for an annealing furnace. Summary of the Invention

The outer side of the material rack base is provided with a feeding cart chassis, a caster assembly mounted on the feeding cart chassis, a vertical plate mounted on the feeding cart chassis, a lifting mechanism mounted on the vertical plate, and a transport bracket connected to the lifting mechanism. The transport bracket is equipped with a clamping component and at least two sets of loading and unloading gripper components. The clamping component can drive two of the loading and unloading gripper components to move closer to each other and clamp the take-up drum located between the two sets of loading and unloading gripper components.

[0007] Preferably, a base plate is provided on the upper side of the rack base, the base plate and the rack base are rotatably engaged, the storage support is installed on the base plate, a rotating shaft is provided on the lower side of the base plate, and the rack base is rotatably engaged with the rotating shaft.

The slider is installed on the transport bracket. There are two guide rails, and the two guide rails are symmetrically distributed about the center line of the transport bracket.

[0012] Preferably, the clamping assembly includes a clamping operating shell, a clamping plate that slides with the clamping operating shell, a lead screw that is threadedly connected to the clamping plate and rotatably installed in the clamping operating shell, and a clamping motor connected to the lead screw. The clamping motor is installed on the clamping operating shell through a motor bracket. There are two clamping plates, and the threads of the lead screw at the two clamping plates have opposite directions. The loading and unloading gripper assembly is installed on the clamping plates.

[0013] Preferably, the clamping plate includes a horizontal plate and a rib plate mounted on the horizontal plate, the rib plate being mounted on the side of the horizontal plate away from the loading / unloading gripper assembly.

[0014] Preferably, the loading and unloading gripper assembly includes a gripper bracket, a positioning disc mounted on the gripper bracket, a drive roller rotatably mounted on the gripper bracket, and a drive motor mounted on the gripper bracket for driving the drive roller to rotate.

During the rotation of the lead screw, it can drive the two clamping plates on it to move closer or further apart. When the two clamping plates move closer together, the loading and unloading gripper assembly on the clamping plates can clamp the winding drum. With the help of the lifting mechanism, the clamped winding drum can be pulled out from the storage support or placed into the storage support, realizing the loading and unloading operation of the winding drum. Compared with the operation method using hoisting tools, the above operation method does not require manual fixing of the winding drum, saving some of the work of the staff and helping to reduce the workload of the staff.

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1-6 As shown in the figure, an embodiment of the present invention provides a multi-layer annealing rack for an annealing furnace, including a rack base 1 and a storage support column 3. A rack bottom plate 2 is provided on the upper side of the rack base 1, and the rack bottom plate 2 and the rack base 1 are rotatably connected. The storage support column 3 is installed on the rack bottom plate 2. Specifically, a rotating shaft can be provided on the lower side of the rack bottom plate 2, and the rack base 1 is rotatably connected with the rotating shaft.

[0022] Specifically, the storage support column 3 is used to store the winding drum 4. In order to reduce the weight of the storage support column 3, a through hole is provided in the center of the storage support column 3. A support ring is provided in the through hole to support the inner wall of the through hole and prevent the storage support column 3 from bending due to the excessive weight of the winding drum 4. The winding drum 4 is used to store the wound steel strip. Figure 2 This is a structural diagram with part of the storage pillar 3 hidden, in order to make it easier to see the structure of components such as the storage pillar 3.

[0023] Specifically, refer to Figure 2 , Figure 5 The storage support column 3 is provided with a vertical groove 301 and a horizontal groove 302 that communicates with the vertical groove 301 and is provided on the outer wall of the storage support column 3. The winding drum 4 is provided with a roller 401 that is inserted and cooperates with the storage support column 3 and a positioning block 402 that is installed on the roller 401 and cooperates with the vertical groove 301. The positioning block 402 and the horizontal groove 302 are rotatably cooperated. A single roller 401 is provided with four positioning blocks 402. Correspondingly, the storage support column 3 is provided with four corresponding horizontal grooves 302. The positioning blocks 402 are arranged vertically aligned and distributed in pairs. The two groups of positioning blocks 402 are arranged in a circumferential array around the center line of the roller 401.

[0024] Insert the take-up drum 4 into the storage support column 3 from top to bottom, align the positioning block 402 with the vertical groove 301, and move the take-up drum 4 downward along the vertical groove 301. When it reaches the height of the horizontal groove 302, rotate the take-up drum 4 so that it rotates around the center line of the storage support column 3. At this time, the positioning block 402 is inserted into the horizontal groove 302. In this way, the vertical position of the take-up drum 4 is fixed. Under the action of its own gravity, the take-up drum 4 can be stably stored on the storage support column 3. Repeat the above operation in reverse to remove the take-up drum 4 from the storage support column 3. This can quickly complete the loading and unloading of the take-up drum 4.

[0025] To facilitate the placement or removal of the winding drum 4 from the storage support column 3, a feeding cart chassis 5, a caster assembly 6 mounted on the feeding cart chassis 5, a vertical plate 8 mounted on the feeding cart chassis 5, a lifting mechanism 9 mounted on the vertical plate 8, and a transport bracket 10 connected to the lifting mechanism 9 are provided on the outside of the material rack base 1. The feeding cart chassis 5 is provided with support legs 7, which are connected to the vertical plate 8. There are two support legs 7, and the two support legs 7 are symmetrically distributed about the center line of the feeding cart chassis 5.

[0026] The lifting mechanism 9 can drive the transport bracket 10 to move up and down. Specifically, it can adopt a gear or rack drive structure, a threaded rod or threaded sleeve travel structure, or a cylinder or other components as the drive structure. The main function is to drive the transport bracket 10 to move in a direction parallel to the center line of the storage column 3. If controlled by a cylinder, the output end of the cylinder can be connected to the transport bracket 10, and the cylinder is installed on the chassis 5 of the feeding car.

[0027] In order to restrict and guide the movement of the transport bracket 10, a slider 16 and a guide rail 17 are provided on the vertical plate 8. The guide rail 17 is vertically installed on the vertical plate 8 and slides with the slider 16. The slider 16 is installed on the transport bracket 10. There are two guide rails 17, and the two guide rails 17 are symmetrically distributed about the center line of the transport bracket 10.

[0028] In order to place the take-up drum 4 onto the storage support 3 or remove it from the storage support 3, the transport bracket 10 is provided with a clamping assembly and at least two sets of loading and unloading gripper assemblies 15. The clamping assembly can drive two of the sets of loading and unloading gripper assemblies 15 to move closer to each other and clamp the take-up drum 4 located between the two sets of loading and unloading gripper assemblies 15.

[0029] Specifically, the clamping assembly includes a clamping operating housing 11, a clamping plate 12 that slides with the clamping operating housing 11, a lead screw 13 that is threadedly connected to the clamping plate 12 and rotatably installed in the clamping operating housing 11, and a clamping motor 14 connected to the lead screw 13. The clamping motor 14 is installed on the clamping operating housing 11 through a motor bracket. There are two clamping plates 12, and the threads of the lead screw 13 at the two clamping plates 12 have opposite directions. The loading and unloading gripper assembly 15 is installed on the clamping plate 12.

[0030] After the clamping motor 14 is turned on, it can drive the lead screw 13 to rotate. During the rotation of the lead screw 13, it can drive the two clamping plates 12 on it to move closer or further apart. When the two clamping plates 12 move closer to each other, the loading and unloading gripper assembly 15 on the clamping plate 12 can clamp the take-up drum 4. In conjunction with the lifting mechanism 9, the clamped take-up drum 4 can be pulled out from the storage support column 3 or placed into the storage support column 3, realizing the loading and unloading operation of the take-up drum 4. Compared with the operation method of using hoisting tools, the above operation method does not require manual fixing of the take-up drum 4, saving some of the work of the staff and helping to reduce the workload of the staff.

[0031] It should be noted that the clamping plate 12 includes a horizontal plate and a rib plate installed on the horizontal plate. The rib plate is installed on the side of the horizontal plate away from the loading and unloading gripper assembly 15.

[0032] Reference Figure 3-6 The loading and unloading gripper assembly 15 includes a gripper bracket 1501, a positioning plate 1503 mounted on the gripper bracket 1501, a drive roller 1504 rotatably mounted on the gripper bracket 1501, and a drive motor 1505 mounted on the gripper bracket 1501 for driving the drive roller 1504 to rotate. There are two positioning plates 1503. The roller 401 has two mounting parts, one of which is located at the top of the roller 401 and the other is located at the bottom of the roller 401. The distance between the two positioning plates 1503 is equal to the thickness of the mounting part.

[0033] When the loading / unloading gripper assembly 15 approaches the take-up drum 4, the positioning plate 1503 inside it is inserted into the mounting position of the take-up drum 4. The drive motor 1505 is turned on, which can drive the drive roller 1504 to rotate. The drive roller 1504 abuts against the outer wall of the take-up drum 4. During the rotation of the drive roller 1504, it can push the take-up drum 4 and the positioning block 402 inside it to rotate. The positioning block 402 rotates to the position of the vertical groove 301. At this time, the lifting mechanism 9 is turned on. During the process of the lifting mechanism 9 driving the transport bracket 10 and other components to move upward, the positioning plate 1503 located below the take-up drum 4 can support the take-up drum 4 and drive the take-up drum 4 to move upward, thereby removing the take-up drum 4 from the storage support column 3. In this way, the loading / unloading operation of the take-up drum 4 is completed.

[0034] It should be noted that a positioning rod 1502 is provided at the gripper bracket 1501, and the positioning rod 1502 is inserted into the center line position of the positioning plate 1503.

[0035] In summary, this embodiment of the invention provides a multi-layer annealing material rack for an annealing furnace. The take-up drum 4 is inserted into the storage support column 3 from top to bottom, and the positioning block 402 is aligned with the vertical groove 301. The take-up drum 4 moves downward along the vertical groove 301. When it reaches the height of the horizontal groove 302, the take-up drum 4 is rotated so that it rotates around the center line of the storage support column 3. At this time, the positioning block 402 is inserted into the horizontal groove 302. In this way, the vertical position of the take-up drum 4 is fixed. Under the action of its own gravity, the take-up drum 4 can be stably stored on the storage support column 3. By reversing the above operation, the take-up drum 4 can be removed from the storage support column 3. In this way, the loading and unloading of the take-up drum 4 can be completed quickly.

[0036] After the clamping motor 14 is turned on, it can drive the lead screw 13 to rotate. During the rotation of the lead screw 13, it can drive the two clamping plates 12 on it to move closer or further apart. When the two clamping plates 12 move closer to each other, the loading and unloading gripper assembly 15 on the clamping plate 12 can clamp the take-up drum 4. In conjunction with the lifting mechanism 9, the clamped take-up drum 4 can be pulled out from the storage support column 3 or placed into the storage support column 3, realizing the loading and unloading operation of the take-up drum 4. Compared with the operation method of using hoisting tools, the above operation method does not require manual fixing of the take-up drum 4, saving some of the work of the staff and helping to reduce the workload of the staff.

[0037] When the loading / unloading gripper assembly 15 approaches the take-up drum 4, the positioning plate 1503 inside it is inserted into the mounting position of the take-up drum 4. The drive motor 1505 is turned on, which can drive the drive roller 1504 to rotate. The drive roller 1504 abuts against the outer wall of the take-up drum 4. During the rotation of the drive roller 1504, it can push the take-up drum 4 and the positioning block 402 inside it to rotate. The positioning block 402 rotates to the position of the vertical groove 301. At this time, the lifting mechanism 9 is turned on. During the process of the lifting mechanism 9 driving the transport bracket 10 and other components to move upward, the positioning plate 1503 located below the take-up drum 4 can support the take-up drum 4 and drive the take-up drum 4 to move upward, thereby removing the take-up drum 4 from the storage support column 3. In this way, the loading / unloading operation of the take-up drum 4 is completed.

[0038] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
