Description

Technical Field

[0001] This utility model relates to the field of cold-rolled steel coil feeding technology, specifically to cold-rolled steel coils. Background Technology

[0002] Cold-rolled steel coils typically weigh several to tens of tons each, and have large diameters and widths. They are difficult to handle manually or with ordinary equipment. They usually require a high-strength loading trolley for handling or loading to achieve continuous material supply in the cold rolling production line.

[0003] Traditional cold-rolled steel coil loading trolleys typically have a recessed slot. A lifting device is used to hoist the cold-rolled steel coil into this slot, where it is held in place by the slot wall. The drawback of this method is that the stability of the cold-rolled steel coil relies entirely on the contact with the slot wall and its own weight. There is a lack of structural constraints to limit the coil's displacement on the trolley. This means that when the trolley's trajectory changes (e.g., turning, or emergency stop), the large inertia caused by its mass can easily cause the coil to detach from the slot and slide out, potentially leading to an accident. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a loading trolley for producing cold-rolled steel coils, thereby solving the problem of the lack of displacement restriction for cold-rolled steel coils after loading in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides

[0007] Optionally, the rotating assembly includes a rotating platform rotatably connected to the vehicle body, and the support platform is fixed on the rotating platform.

[0008] Optionally, a support column is rotatably connected to the bottom of the rotating platform, the support column is fixed to the vehicle body, a toothed groove is provided on the side of the rotating platform, and a gear meshing with the toothed groove is provided on the vehicle body, the gear being driven by a motor.

[0009] Optionally, the support assembly includes two symmetrically arranged side support seats. A side support circular plate is fixed on one side of the two side support seats that are close to each other. A threaded plate is also fixed on one side of the two side support seats that are close to each other. A first lead screw is threadedly connected to the threaded plate. The first lead screw is rotatably connected to the vehicle body and is driven to rotate by a motor installed in the vehicle body.

[0010] Optionally, the clamping assembly includes a plurality of clamping plates arranged in a circumferential pattern. A threaded cylinder is provided within the circumference of the arrangement. The clamping plates and the threaded cylinder are connected by a rotating rod. A second lead screw is threadedly connected inside the threaded cylinder. One end of the second lead screw passes through a side support circular plate and is driven to rotate by a fixed motor. The other end of the second lead screw is rotatably connected to a lead screw bracket.

[0011] Optionally, a slider is fixed to one end of the clamping plate near the side support circular plate, and a corresponding groove is provided on the side support circular plate to cooperate with the slider, and the slider slides in the groove.

[0012] Optionally, the support platform has two symmetrically arranged platforms, with an inclined surface on the side of the two platforms that are close to each other, and a reinforcing rib on the side of the two platforms that are far apart from each other.

[0013] Optionally, the track has two bosses, and wheel grooves are provided on the side of the two bosses that are far apart from each other.

[0014] Optionally, the vehicle body is provided with a sliding groove for use with the boss, and the vehicle body is also provided with a number of wheels, which are driven by a drive structure to roll in the wheel groove.

[0015] Optionally, the side support seat has several grooves on the side near the vehicle body, and several ball bearings are rotatably connected in the grooves, the ball bearings rolling on the vehicle body.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention, after the cold-rolled steel coil is hoisted onto the support platform, uses a driving rotating component to reverse the orientation of the coil. By adjusting the relative positions of the support components and the clamping components, the cold-rolled steel coil is laterally clamped, ensuring lateral support during transport. This avoids the danger of displacement caused by external forces or inertia during movement.

[0018] The clamping assembly of this invention uses several clamping plates to clamp cold-rolled steel coils from the inner ring. Furthermore, by adjusting the relative position between the second lead screw and the threaded cylinder, the clamping plates can be moved relative to the threaded cylinder, thereby changing the distance between the clamping plates to accommodate cold-rolled steel coils of different inner diameters.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] As mentioned earlier, traditional cold-rolled steel coil loading trolleys typically have a recessed slot. A hoisting device is used to lift the cold-rolled steel coil into this slot, where it is held by the slot wall. The drawback of this method is that the stability of the cold-rolled steel coil relies entirely on the contact with the slot wall and its own weight. There is a lack of structural constraints to limit the coil's displacement on the trolley. This means that when the trolley's trajectory changes (e.g., turning, emergency stop), the large inertia caused by its mass makes it easy for the coil to slip out of the slot and cause an accident. To address this, this invention provides a loading trolley specifically designed for the transportation and loading of cold-rolled steel coils, solving the aforementioned problems. This invention solves the problem in the following way.

[0030] Example 1:

[0031] Please refer to the instruction manual appendix. Figures 1 to 6 As shown in the figure, this utility model discloses a loading trolley for producing cold-rolled steel coils. The loading trolley includes a body 1, a support platform 2, a rotating assembly 3, a movable structure 4, and a track 5 for moving the body 1. The body 1 has two parallel sliding grooves 11 and four wheels 12 distributed on both sides of the sliding grooves 11 (e.g., ...). Figure 6 (As shown). Correspondingly, two protrusions 51 are provided on the track 5. In use, the protrusions 51 slide in the sliding groove 11. The two protrusions 51 are located on opposite sides of each other and are provided with wheel grooves 52 on the track 5. In use, the four wheels 12 driven by the vehicle body 1 through an additional drive structure (e.g., motor, engine) roll in the wheel grooves 52, thereby enabling the vehicle body 1 to move within the track 5.

[0032] In this first embodiment, one preferred implementation is that four sliding grooves 11 are provided, each located next to the wheel 12. The width and height of the sliding grooves 11 are adapted to the width and height of the boss 51, and the length of the sliding grooves 11 is equal to the length of the wheel 12. This allows two sliding grooves 11 located on the same side to slide along the non-linear track 5 when the track 5 is not straight, enabling the vehicle body 1 to adapt to more diverse movement needs.

[0033] In this first embodiment, as Figure 5 As shown, the support platform 2 is used to support the cold-rolled steel coil. The support platform 2 has two symmetrically arranged platform bodies 21. An inclined surface 22 is provided on the side of the two platform bodies 21 that is close to each other. The two inclined surfaces 22 are symmetrically arranged to form an area for placing the cold-rolled steel coil. In use, a hoisting device is used to hoist the cold-rolled steel coil into this area. The inclined surfaces 22 abut against the contact surface of the cold-rolled steel coil, thus providing support. Reinforcing ribs 23 are provided on the side of the two platform bodies 21 that is far apart from each other. This further strengthens the support provided by the support platform 2 for the cold-rolled steel coil.

[0034] In this first embodiment, a rotating platform 31 is fixedly connected to the side of the support platform 2 closest to the vehicle body 1 (i.e., the bottom surface), and a support column 32 is rotatably connected to the rotating platform 31 (e.g., ...). Figure 4 As shown), the support column 32 is fixed to the vehicle body 1, which allows the support platform 2 and the rotating platform 31 to rotate relative to the vehicle body 1. Meanwhile, the rotating platform 31 has toothed grooves 311 on its side (as shown). Figure 1 or Figure 2 As shown in the figure, a gear 33 meshing with a toothed groove 311 is provided on the vehicle body 1. The gear 33 is driven to rotate by a motor installed inside the vehicle body 1 (the motor is not shown in the figure). The aforementioned rotating platform 31, toothed groove 311, support column 32, gear 33, and motor driving the gear 33 together constitute the rotating assembly 3 of this embodiment. This allows the support platform 2 to rotate at any angle after carrying the cold-rolled steel coil, thereby meeting various turning requirements during transportation.

[0035] After the support platform 2 carries the cold-rolled steel coil and rotates to a specified angle, it needs to limit the movement of the coil at that angle. This function relies on the movable structure 4 mounted on the vehicle body 1. Therefore, in this embodiment, the movable structure 4 includes a support assembly 41 and a clamping assembly 43. Figure 2 , Figure 4 As shown, the support assembly 41 includes two symmetrically arranged side support seats 411. A side support circular plate 412 is fixed on the side of the two side support seats 411 that are close to each other, and the clamping assembly 43 is disposed on the side support circular plate 412. At the same time, a threaded plate 413 is also fixed on the side of the two side support seats 411 that are close to each other. The threaded plate 413 is crescent-shaped and located between the rotating platform 31 and the vehicle body 1. Two first lead screws 42 are threadedly connected to the threaded plate 413. The two first lead screws 42 are rotatably connected to the vehicle body 1 and are driven to rotate by a motor disposed in the vehicle body 1.

[0036] Because the threads connecting the two threaded plates 413 and the first lead screw 42 are opposite, when the motor drives the first lead screw 42 to rotate, the two threaded plates 413 move apart or closer together. When the two side support seats 411 move to contact the side of the rotating platform 31, the two threaded plates 413 are closest together; when the two side support seats 411 move to contact the vehicle body 1, the two threaded plates 413 are furthest apart. To avoid motion interference, it should be noted that the distance between the two first lead screws 42 should be less than the diameter of the support column 32; when the two side support seats 411 move to their closest point, the two threaded plates 413 do not come into contact with the support column 32. Simultaneously, when the threaded plates 413 move on the two first lead screws 42, they do not come into contact with the gear 33 or the output shaft of the motor driving the gear 33.

[0037] Therefore, in the specific implementation of this embodiment, the loading trolley needs to be initially set. In the initial state, the connecting line between the inclined surfaces 22 on the two platform bodies 21 of the support platform 2 should be parallel or coincident with the connecting line between the two side support seats 411. At this time, the two side support seats 411 and the clamping components 43 on them are located at the farthest position. Then, an additional hoisting device is used to hoist the cold-rolled steel coil between the two inclined surfaces 22 to realize the support platform 2 supporting the cold-rolled steel coil. At this time, the connecting line between the two through holes of the cold-rolled steel coil is perpendicular to the connecting line between the two side support seats 411. Then, the drive gear 33 rotates, and under the meshing action with the tooth groove 311, the rotating platform 31 drives the support platform 2 to rotate. When it rotates to 90°, that is, the connecting line between the inclined surfaces 22 on the two platform bodies 21 of the support platform 2 is perpendicular to the connecting line between the two side support seats 411. At this time, the connecting line between the two through holes of the cold-rolled steel coil is perpendicular to the connecting line between the two side support seats 411. Then, the first lead screw 42 is driven to rotate, causing the two threaded plates 413 to move in similar directions, and causing the two clamping components 43 to move closer to the two through-holes of the cold-rolled steel coil. Until the two side support seats 411 are in contact with the rotating table 31, the two clamping components 43 are closest together, and the side support circular plates 412 are in contact with the side wall of the cold-rolled steel coil. The clamping components 43 then clamp the inner diameter of the cold-rolled steel coil. This completes the lateral limiting of the cold-rolled steel coil during the movement of the loading trolley, preventing it from coming off due to changes in its movement trajectory. Subsequently, the drive structure of the driving body 1 moves the car body 1 on the track 5 until it reaches the designated position. The above operation is then repeated in reverse to release the lateral limiting of the cold-rolled steel coil. At this point, an additional lifting structure is used to lift the cold-rolled steel coil to the designated position, completing the loading operation.

[0038] Example 2:

[0039] Based on the above embodiments, in order to provide a clearer and more complete explanation of the technical solutions therein, this utility model also provides an embodiment two. For example... Figures 2 to 3 As shown, in this second embodiment, the clamping assembly 43 includes three circumferentially distributed clamping plates 431. A threaded cylinder 432 is disposed in the center of the circumferentially distributed clamping plates 431. A rotating rod 433 is rotatably connected to the threaded cylinder 432, and the end of the rotating rod 433 away from the threaded cylinder 432 is rotatably connected to the clamping plate 431. A slider is fixed to one end of the clamping plate 431 near the side support circular plate 412. A corresponding groove 4121 is provided on the side support circular plate 412 to cooperate with the slider, and the slider slides within the groove 4121. Therefore, when the threaded cylinder 432 moves along an axis parallel to the clamping plate 431, it changes the angle between itself and the rotating rod 433, causing the rotating rod 433 to rotate. This, in turn, changes the distance between the clamping plate 431 and the threaded cylinder 432, thereby achieving distance adjustment between the clamping plates 431. This distance adjustment method can be applied to clamping or releasing the inner diameter of cold-rolled steel coils, and can also be applied to adjusting the clamping of cold-rolled steel coils with different inner diameters.

[0040] To achieve the above process, in this second embodiment, a second lead screw 434 is internally threaded onto the threaded cylinder 432. One end of the second lead screw 434 passes through the side support circular plate 412 and is driven to rotate by a motor (the motor is fixed to the side support circular plate 412 or to the side support base 411). The other end of the second lead screw 434 is rotatably connected to a lead screw bracket 435. When the motor drives the rotation, the second lead screw 434 rotates, and under the influence of the threaded connection, the position of the threaded cylinder 432 is changed to achieve the aforementioned distance adjustment of the clamping plate 431.

[0041] It should be noted that when the two side support seats 411 are at their furthest distance, the distance between the clamping plates 431, the second lead screw 434, or the lead screw support 435 on both sides should be greater than the longest length of the cold-rolled steel coil. In this way, when the cold-rolled steel coil rotates with the turntable 31, it will not touch the clamping plates 431, the second lead screw 434, or the lead screw support 435.

[0042] Example 3:

[0043] Based on the above embodiments, in order to provide a clearer and more complete explanation of the technical solutions, this utility model also provides a third embodiment. In this third embodiment, the side support 411 has several grooves on its side near the vehicle body 1, and several ball bearings are rotatably connected in these grooves, rolling on the vehicle body 1. This reduces the friction between the side support 411 and the vehicle body 1 during movement, thereby improving the efficiency of movement.

[0044] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
