Description

Technical Field

[0001] This invention relates to the field of transfer cart technology, and in particular to a transfer cart for the production of galvanized steel coils. Background Technology

[0002] In the production and processing of galvanized steel coils, the coils undergo multiple processes such as pickling, galvanizing, cooling, and coiling. The transfer links between these processes are crucial for ensuring production continuity and product quality. However, the galvanized steel coil transfer equipment currently widely used in the industry still has many technical challenges in practical applications.

[0003] Existing transfer equipment often uses single supports or simple binding methods to fix steel coils, which is difficult to adapt to steel coils with different inner diameters and diameter specifications. This can easily lead to problems such as the steel coil swaying along the axis and axial movement. Especially during transfer conditions such as turning and starting / stopping, the reliability of fixing is further reduced, which may cause scratches on the surface of the steel coil and peeling off the galvanized layer, affecting product quality. When transferring steel coils, they need to be accurately fitted onto the fixing components. Existing equipment lacks an effective guiding structure, and the alignment process relies on manual visual inspection and repeated adjustments. This is not only time-consuming and labor-intensive, increasing the labor intensity of workers, but also prone to steel coil collisions and component wear due to alignment deviations, reducing transfer efficiency. Galvanized steel coils have a certain tendency to release tension after being coiled. Existing transfer equipment does not have a specific anti-breakage structure. During the transfer process, the steel coil may loosen between layers or even break apart due to external forces such as vibration and tilting, causing safety accidents and scrapping the steel coil, increasing production costs.

[0004] Therefore, this application provides a transfer trolley for galvanized steel coil production to meet the demand. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a transfer trolley for the production of galvanized steel coils, so as to solve the problems of insufficient fixation stability, cumbersome operation of coil stacking, and lack of risk control for breakage.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A transfer trolley for producing galvanized steel coils includes a handcart with an inner support assembly. A guide and fixing assembly is located at the front end of the inner support assembly. A lifting platform is located below the inner support assembly, and a bottom fixing assembly is located on the lifting platform. Anti-splitting components are located on both sides of the bottom fixing assembly. Steel coils can be placed on the inner support assembly. The handcart contains a hydraulic power system that powers the inner support assembly and the lifting platform. A storage battery is also installed inside the handcart. The inner support assembly is located at the center of the handcart and is used to fix the inner diameter of the steel coil. The guide and fixing assembly is coaxial with the inner support assembly and is used to guide the placement of the steel coil and fix its end face. The bottom fixing assembly is located directly below the guide and fixing assembly and the inner support assembly, and is used to fix the bottom of the steel coil. The anti-splitting components are rotatable around the axis of the guide and fixing assembly and the inner support assembly, and are used to prevent the steel coil from splitting during transfer.

[0007] Optionally, the internal support assembly includes an internal support column, an mounting plate is fixedly connected inside the internal support column, a hydraulic rod is mounted on the mounting plate, and a support plate is fixedly connected to the hydraulic rod.

[0008] Optionally, the guide fixing assembly includes a limiting box, a motor is installed inside the limiting box, a drive shaft is driven to the drive end of the motor, an active bevel gear is sleeved on the drive shaft, and four driven bevel gears are meshed with the active bevel gear.

[0009] Optionally, the driven bevel gear is sleeved on the threaded rod, the threaded rod is threadedly connected to the inside of the threaded sleeve, the other end of the threaded sleeve extends out of the limiting box, a guide block is installed at the other end of the threaded sleeve, a plurality of springs are installed inside the guide block, a connecting rod is fixedly connected to the mounting seat of the springs, and a guide wheel is rotatably connected to the connecting rod.

[0010] Optionally, both sides of the threaded sleeve are fixedly connected to end face fixing plates, and a compensation plate is slidably connected between two adjacent end face fixing plates.

[0011] Optionally, a hydraulic rod is installed at the bottom of the lifting platform, and a groove is provided on the lifting platform, in which a bottom fixing component is slidably connected.

[0012] Optionally, the bottom fixing assembly includes a fixing platform, a spring 2 is installed at the bottom of the fixing platform, racks are provided on both sides of the fixing platform, a rotating shaft is rotatably connected in the groove, a driven gear is sleeved on the rotating shaft, the racks and the driven gear are meshed, and a limit plate is fixedly connected in the groove.

[0013] Optionally, the anti-split assembly is provided in two sets, each including an arc-shaped plate, which is sleeved on the rotating shaft and fits against the side of the steel coil.

[0014] Optionally, the end face fixing plate is provided with a plurality of fitting protrusions, and the arc plate and the fixing platform are provided with fitting grooves and receiving grooves. The fitting protrusions and the fitting grooves fit together, and the receiving grooves can accommodate the guide blocks.

[0015] Optionally, the battery provides power for the movement of the handcart.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up an internal support component and using a hydraulic rod to drive the support plate to expand outward, it can closely fit the inner diameter of the steel coil. The inward support force effectively prevents the steel coil from swaying along the axis, improves the fixing stability, and the expansion force is controllable and uniform. It can adapt to steel coils with different inner diameter specifications, has strong versatility, and does not require the replacement of suitable parts for specific steel coils.

[0017] By incorporating a guide and fixing assembly, the system combines the functions of guiding and fixing the coil at the end face. The motor drives the bevel gear set to link the threaded rod and the threaded sleeve, which can precisely adjust the position of the guide block. In conjunction with the guide wheel and spring 1, the guide wheel rolls to reduce frictional resistance during the coil fitting process, while spring 1 can adapt to slight changes in the inner diameter, guiding the coil to be precisely fitted onto the inner support assembly, reducing alignment time and operational difficulty. The end face fixing plate moves with the threaded sleeve to achieve axial positioning of the coil, and the compensation plate between adjacent fixing plates can fill the end face gap, ensuring the sealing and stability of the end face fixing and preventing axial movement of the coil.

[0018] With the bottom fixing component, the spring at the bottom of the fixing platform can buffer the weight pressure of the steel coil, avoiding damage to the steel coil due to rigid contact, and also playing a shock absorption role; the rack and pinion mesh with the driven gear to ensure synchronous lifting and lowering on both sides of the fixing platform, so that the bottom of the steel coil is evenly stressed and the support stability is improved; the limit plate can limit the downward stroke of the fixing platform, prevent excessive compression of the spring and damage to the components, and form a coordinated upper and lower fixing with the inner support component, further preventing slippage during the transfer of the steel coil.

[0019] Equipped with anti-splitting components, the curved plate can rotate around its axis and fit tightly against the side of the steel coil, forming a lateral protective barrier. This effectively addresses the risk of the steel coil splitting due to vibration or tilting during transport, improving operational safety. Through gear and rack linkage with the bottom fixing components, bottom fixing and lateral protection can be operated simultaneously, simplifying the work process. The fitting grooves on the curved plate and the fixing platform can interlock with the fitting protrusions on the end face fixing plate, enhancing the stability of the component connections. The storage slots can accommodate guide wheels and guide blocks, preventing component interference and ensuring the fit between the curved plate and the side of the steel coil, improving protective reliability. A battery provides power to the drive motor when the trolley is moved, driving the wheels to rotate, reducing worker fatigue, improving transport convenience, and adapting to the flexible movement needs in production scenarios.

[0023] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0024] The following is a detailed description of a transfer trolley for producing galvanized steel coils provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0025] like Figures 1 to 11As shown, an embodiment of the present invention provides a transfer trolley for producing galvanized steel coils 7, including a handcart 1, an inner support assembly 2 on the handcart 1, a guide fixing assembly 3 at the front end of the inner support assembly 2, a lifting platform 4 below the inner support assembly 2, a bottom fixing assembly 5 on the lifting platform 4, and anti-split components 6 on both sides of the bottom fixing assembly 5. The inner support assembly 2 can hold the steel coil 7. A hydraulic power system 8 is installed inside the handcart 1, supplying power to the inner support assembly 2 and the lifting platform 4. A battery 9 is installed inside the handcart 1. The inner support assembly 2 is located at the center of the handcart 1 and is used to fix the inner diameter of the steel coil 7. The guide fixing assembly 3 is coaxially arranged with the inner support assembly 2 and is used to guide the placement of the steel coil 7 and fix its end face. The bottom fixing assembly 5 is located directly below the guide fixing assembly 3 and the inner support assembly 2. 5 is used to fix the bottom of the steel coil 7. The anti-splitting component 6 can rotate around the axis of the guide fixing component 3 and the inner support component 2. The anti-splitting component 6 is used to prevent the steel coil 7 from splitting during transportation. The battery 9 provides power for the movement of the handcart 1. The guide block 308 is adjusted to match the inner diameter of the steel coil 7 by the bevel gear set driven by the motor 302. The guide wheel 314 rolls to reduce the fitting friction. The spring 312 can adapt to slight changes in the inner diameter and guide the steel coil 7 to be accurately fitted on the inner support component 2, reducing the alignment time and operation difficulty. The hydraulically driven support plate 204 of the inner support component 2 expands evenly to fit the inner diameter of the steel coil 7 to prevent shaking. The bottom fixing component 5 spring buffer and gear rack 503 synchronously lift and lower to achieve uniform support and reduce the risk of sliding. The arc plate 601 rotates around the axis to fit the side of the steel coil 7 to form lateral protection and is fitted with the end face fixing plate 309 to strengthen the connection, effectively avoiding the problem of splitting caused by vibration and tilting during transportation.

[0026] like Figure 3 As shown, the inner support assembly 2 includes an inner support column 201, with an installation plate 202 fixedly connected inside the inner support column 201. A hydraulic rod 203 is installed on the installation plate 202, and a support plate 204 is fixedly connected to the hydraulic rod 203. The inner support assembly 2 drives the support plate 204 to expand outward through the hydraulic rod 203, directly acting on the inner diameter of the steel coil 7 to achieve a tight fit. The expansion force of the hydraulically driven support plate 204 is controllable and uniform, and can be adapted to steel coils 7 with different inner diameter specifications, with strong versatility. At the same time, the inward supporting force can effectively prevent the steel coil 7 from swaying along the axis during transportation, improving the fixing stability.

[0027] like Figures 4 to 7As shown, the guide fixing assembly 3 includes a limiting box 301, inside which a motor 302 is installed. The drive end of the motor 302 is driven by a drive shaft 303. A drive bevel gear 304 is sleeved on the drive shaft 303. The drive bevel gear 304 is meshed with four driven bevel gears 305. The driven bevel gears 305 are sleeved on a threaded rod 306. The threaded rod 306 is threadedly connected to the inside of a threaded sleeve 307. The other end of the threaded sleeve 307 extends out of the limiting box 301. A guide block 308 is installed at the other end of the threaded sleeve 307. Several springs 312 are installed inside the guide block 308. A connecting rod 313 is fixedly connected to the mounting seat of the springs 312. A guide wheel 314 is rotatably connected to the connecting rod 313. End face fixing plates 309 are fixedly connected to both sides of the threaded sleeve 307. Compensating plates 311 are slidably connected between the end face fixing plates 309. The guide fixing assembly 3 has the dual functions of guiding and fixing the end face, which is highly practical. The motor 302 drives the bevel gear set to drive the threaded rod 306 and the threaded sleeve 307 to move together, so that the guide block 308 is precisely adjusted to the position that matches the inner diameter of the steel coil 7. With the design of the guide wheel 314 and the spring 312, the steel coil 7 is fitted and the guide wheel 314 rolls to reduce frictional resistance. The spring 312 can adapt to slight changes in the inner diameter and guide the steel coil 7 to be precisely fitted on the inner support assembly 2, reducing the alignment time and operation difficulty during the fitting process. The end face fixing plate 309 moves with the threaded sleeve 307 to realize the axial limit of the steel coil 7. The compensating plate 311 between adjacent fixing plates can fill the end face gap, ensuring the sealing and stability of the end face fixing and preventing the steel coil 7 from moving axially.

[0028] like Figure 8 As shown, a hydraulic rod 401 is installed at the bottom of the lifting platform 4. A groove 402 is provided on the lifting platform 4. A bottom fixing component 5 is slidably connected in the groove 402. The bottom fixing component 5 includes a fixing platform 501. A spring 502 is installed at the bottom of the fixing platform 501. Racks 503 are provided on both sides of the fixing platform 501. A rotating shaft 504 is rotatably connected in the groove 402. A driven gear 505 is sleeved on the rotating shaft 504. The racks 503 and the driven gear 505 are meshed. A limit plate 506 is fixedly connected in the groove 402. The lifting platform 4 is raised and lowered by the hydraulic rod 401, which can be adjusted according to the steel coil. The bottom fixing component 5 is height-adjustable to accommodate steel coils 7 of different specifications. In the bottom fixing component 5, the fixing platform 501 buffers the weight pressure of the steel coil 7 through the second spring 502 to avoid damage caused by rigid contact. At the same time, the rack 503 meshes with the driven gear 505 to ensure that the two sides of the fixing platform 501 rise and fall synchronously, so that the bottom of the steel coil 7 is evenly stressed. The limiting plate 506 can limit the downward stroke of the fixing platform 501 to prevent excessive compression of the second spring 502 from causing damage to the components. The overall structure provides stable support for the bottom of the steel coil 7 and forms a coordinated fixation with the inner support component 2, further improving the placement stability of the steel coil 7.

[0029] like Figures 9 to 11 As shown, the anti-splitting assembly 6 is provided in two sets. The anti-splitting assembly 6 includes an arc-shaped plate 601, which is sleeved on the rotating shaft 504. The arc-shaped plate 601 fits against the side of the steel coil 7. The end face fixing plate 309 is provided with several fitting protrusions 310. The arc-shaped plate 601 and the fixing platform 501 are provided with fitting grooves 602 and storage grooves 603. The fitting protrusions 310 fit into the fitting grooves 602. The storage grooves 603 can accommodate the guide wheel 314. The anti-splitting assembly 6 achieves a tight fit with the side of the steel coil 7 by rotating the arc-shaped plate 601 around the axis, forming lateral protection. The barrier specifically addresses the risk of breakage due to vibration and tilting during the transport of steel coil 7, improving operational safety. The arc-shaped plate 601 and the bottom fixing component 5 are linked by a gear and rack 503 to achieve simultaneous operation of bottom fixing and lateral protection, simplifying the process. The fitting groove 602 on the arc-shaped plate 601 and the fitting protrusion 310 on the end face fixing plate 309 fit together to enhance the connection stability of each component. At the same time, the storage groove 603 can accommodate the guide wheel 314 to avoid interference between components and ensure the fit between the arc-shaped plate 601 and the side of the steel coil 7, making the protection effect more reliable.

[0030] The working principle of the technical solution provided by this invention is as follows: When the workers transfer the steel coil 7 to the handcart 1, they first lift the steel coil 7 using hoisting tools, then push the handcart 1 towards the steel coil 7 and stop it in front of the steel coil 7. They then visually adjust the position of the steel coil 7 using the hoisting tools to make it approximately aligned with the axis of the inner support assembly 2. Next, they start the motor 302, which drives the drive shaft 303 to rotate, thereby rotating the driving bevel gear 304. The driving bevel gear 304 meshes with four driven bevel gears 305, driving the threaded rod 306 to rotate. The threaded rod 306 is threadedly engaged with the threaded sleeve 307. When the threaded rod 306 rotates, it pushes the threaded sleeve 307 towards the limit. The positioning box 301 extends outward, causing the guide wheel 314 of the guide block 308 to move to a position that matches the inner diameter of the steel coil 7. Then, the position of the steel coil 7 is precisely adjusted using lifting tools so that the inner diameter of the steel coil 7 contacts the guide wheel 314. Then, the motor 302 is turned off, and the handcart 1 is pushed on. The steel coil 7 begins to transfer to the inner support assembly 2. The spring 312 inside the guide block 308 is connected to the guide wheel 314 through the connecting rod 313. During the installation of the steel coil 7, the guide wheel 314 contacts and rolls with the inner diameter of the steel coil 7, reducing the installation resistance. At the same time, the spring 312 can slightly expand and contract according to the inner diameter of the steel coil 7 to achieve adaptive guidance and guide the steel coil 7 to be accurately installed on the inner support assembly 2.

[0031] After the steel coil 7 is installed, the hydraulic power system 8 drives the hydraulic rod 203 in the inner support assembly 2 to extend, pushing the support plate 204 to expand outward until the support plate 204 is tightly fitted with the inner diameter of the steel coil 7. The inner diameter of the steel coil 7 is fixed by the inward supporting force to prevent the steel coil 7 from swaying along the axis during transportation. After the inner support assembly 2 is fixed, the hydraulic power system 8 drives the hydraulic rod 401 to extend, driving the lifting platform 4 to rise, so that the fixing platform 501 of the bottom fixing assembly 5 contacts the bottom of the steel coil 7 and bears the weight of the steel coil 7. The spring 502 at the bottom of the fixing platform 501 is compressed by pressure. At the same time, the racks 503 on both sides of the fixing platform 501 move as the fixing platform 501 descends. The racks 503 mesh with the driven gears 505 on the rotating shaft 504 in the groove 402, driving the rotating shaft 504 to rotate, so that the two sides of the structure are linked synchronously until the fixing platform 501 is tightly fitted with the bottom of the steel coil 7, and the bottom of the steel coil 7 is fixed by the upward supporting force.

[0032] The arc-shaped plate 601 of the anti-splitting component 6 is sleeved on the rotating shaft 504 and can rotate around the axis of the guide fixing component 3 and the inner support component 2. While fixing the bottom of the steel coil 7, the arc-shaped plate 601 meshes with the driven gear 505 on the rotating shaft 504 in the groove 402 through the rack 503, causing itself to rotate so that it fits tightly against the side of the steel coil 7, forming lateral protection to prevent the steel coil 7 from splitting open during transportation.

[0033] After the inner diameter, bottom, and sides of the steel coil 7 are fixed, the motor 302 is restarted. The threaded sleeve 307 drives the end face fixing plates 309 fixed on both sides to move synchronously, axially limiting the steel coil 7. The compensation plate 311 slidably connected between adjacent end face fixing plates 309 is used to fill the end face gap, ensuring the sealing and stability of the end face fixing, until the end face fixing plate 309 and the arc plate 601 come into contact, and the fitting groove 602 on the arc plate 601 and the fitting protrusion 31 on the end face fixing plate 309 are engaged. The components interlock, and the storage groove 603 can accommodate the guide wheel 314 to fix the arc plate 601. It also enhances the connection stability between the components during the transfer process after the steel coil 7 is fixed. The interlocking groove 602 on the fixing platform 501 and the interlocking protrusion 310 on the end face fixing plate 309 interlock. The storage groove 603 can accommodate the guide block 308 to avoid interference between components and ensure the fit between the arc plate 601 and the side of the steel coil 7. It effectively prevents the steel coil 7 from breaking apart due to vibration, tilting or other reasons during the transfer process.

[0034] During the transfer of steel coil 7, the battery 9 simultaneously provides power for the movement of the wheels of the handcart 1 through the built-in drive motor, reducing the physical exertion of the staff.

To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0036] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
