Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, and in particular to steel coil handling and stacking equipment. Background Technology

[0002] Steel coils, as an important intermediate product in steel production and downstream manufacturing, are characterized by their large weight, volume, and cylindrical shape. Frequent handling and stacking of steel coils are required during production, warehousing, and transportation. To achieve this, existing technologies typically employ specialized handling equipment, such as custom-designed trolleys or saddle-type supports.

[0003] However, in actual production, the specifications of steel coils are not static; their width and diameter often vary depending on different orders and process requirements. This places compatibility demands on handling equipment. Currently, some handling equipment uses fixed-width support structures, which are only suitable for steel coils of specific specifications. They become unusable when encountering coils of different widths, resulting in low equipment utilization. This necessitates equipping multiple models of equipment for different specifications of steel coils, increasing equipment costs and warehousing management burdens for enterprises.

[0004] To address this issue, some width-adjustable handling equipment has emerged on the market. However, most of these devices employ manual or asynchronous adjustment methods. Manual adjustment is not only time-consuming and labor-intensive, reducing operational efficiency, but also makes it difficult to guarantee the adjustment accuracy and symmetry of the support structures on both sides. Asynchronous adjustment, on the other hand, can easily lead to asymmetry in the position of the support structures on both sides, causing the center of gravity of the steel coil to shift after placement. This can result in swaying or even tipping over during handling, posing a serious safety hazard and failing to ensure stable, centered support for steel coils of different widths.

[0005] Therefore, this utility model proposes a steel coil handling and stacking device to address the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a steel coil handling and stacking device, which aims to improve the problems in the prior art where the width of the support structure is fixed or manual adjustment is laborious, and it is difficult to ensure the symmetry and accuracy of the adjustment of the support structures on both sides.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a steel coil handling and stacking device, comprising: a base, two side support plates; and a shrinking assembly and an adaptive assembly; The two side support plates are slidably connected to the top surface of the base; The retraction assembly includes a motor, a gear, and two racks. The motor is mounted on the base, the gear is driven and connected to the output shaft of the motor, and the gear is located between the two racks. The tooth surfaces of the two racks are arranged opposite each other and mesh with the opposite sides of the gear. Furthermore, the back of each rack is fixedly connected to the bottom of the corresponding side support plate. The retraction assembly drives the gear to rotate via a motor, thereby causing the two racks to move in opposite directions simultaneously, so as to achieve synchronous and symmetrical adjustment of the distance between the two side support plates. The adaptive component is respectively installed on the two side support plates. The adaptive component includes a sphere and an adaptation plate. The sphere is fixed to the inner side of the side support plate. The adaptation plate is swayably placed above the sphere. The adaptive component swings with the sphere as the universal fulcrum through the adaptation plate to achieve close support for the outer arc surface of the steel coil. Preferably, a plurality of fixing grooves are formed on the top surface of the base along the sliding path of the side support plate; Preferably, the side support plate is provided with a fixing post, which can be inserted and removed through the side support plate to selectively engage and lock with the fixing groove, thereby providing rigid positioning after the side support plate is adjusted into place and preventing its position from shifting. Preferably, the retraction assembly further includes a support frame, which is fixed to the bottom end of the base, and the motor is installed inside the support frame, which provides a stable mounting base and protection for the motor; Preferably, an anti-slip strip is fixed to the surface of the adapting plate facing the center between the two side support plates. The anti-slip strip is used to increase the contact friction and prevent the steel coil from sliding. Preferably, the adaptive component is mounted on the upper inner side of the side support plate; Preferably, a plurality of sliding wheels are fixedly connected to the bottom of the base, and the sliding wheels are used to facilitate the movement of the equipment on the ground; Preferably, the two side support plates are symmetrically arranged along the width direction of the base to ensure the balance of the support.

[0008] This utility model has the following beneficial effects: 1. This utility model solves the problem of existing steel coil handling equipment having fixed support spacing or requiring laborious manual adjustment, making it difficult to adapt to steel coils of different diameters. By setting up a retraction component driven by a motor to simultaneously mesh two opposing racks, it achieves the technical effect of quickly, synchronously and symmetrically adjusting the spacing of the two side support plates, thereby efficiently adapting to various specifications of steel coils and improving the equipment's versatility and loading and unloading efficiency.

[0009] 2. This utility model solves the problems of traditional rigid support structures being difficult to fit with the outer arc surface of the steel coil, prone to rolling instability, and easily scratching the steel coil due to direct metal contact by setting an adaptive component consisting of a sphere and an adaptive plate on the inner side of the side support plate, and setting an anti-slip strip on the surface of the adaptive plate. It achieves the technical effect of automatically adjusting the support angle using the universal fulcrum of the sphere to achieve fit, and increasing friction and buffering protection with the anti-slip strip, thereby significantly improving the storage stability and surface quality of the steel coil.

[0010] 3. This utility model solves the problem that the side support plate is prone to loosening or damage to motor components due to vibration during transportation after it is adjusted to the correct position by setting a fixing groove on the top surface of the base and setting a pluggable fixing column on the side support plate. It achieves the technical effect of rigidly positioning the side support plate, effectively sharing the force load of the transmission mechanism, ensuring reliable locking of the support width during transportation, and preventing accidental slippage.

[0013] 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.

[0014] Reference Figures 1-5The present invention provides an embodiment of a steel coil handling and stacking device, including a base 1 and two side support plates 3 slidably connected to the top surface of the base 1. The two side support plates 3 are symmetrically arranged along the width direction of the base 1. The device also includes a shrinking component 4 and an adaptive component 5. The shrinking component 4 is used to drive the two side support plates 3 to shrink or open synchronously, and the adaptive component 5 is used to stably support the steel coil. Specifically, the shrinking assembly 4 includes a motor 404, a gear 401, and two racks 402. The motor 404 is mounted on the base 1. The gear 401 is driven and connected to the output shaft of the motor 404. The gear 401 is located between the two racks 402. The tooth surfaces of the two racks 402 are arranged opposite each other and mesh with the opposite sides of the gear 401 respectively. The back of each rack 402 is fixedly connected to the bottom of the corresponding side support plate 3. By driving the gear 401 to rotate through the motor 404, the two racks 402 can be driven to move in opposite directions in a straight line synchronously, thereby realizing the symmetrical adjustment of the distance between the two side support plates 3. Furthermore, the adaptive components 5 are respectively installed on the two side support plates 3, and the adaptive components 5 are installed on the inner upper side of the side support plates 3. Each adaptive component 5 includes a ball 503 and an adaptive plate 502. The ball 503 is fixed to the inner side of the side support plate 3, and the adaptive plate 502 is swayably placed above the ball 503. When the steel coil is placed, the adaptive plate 502 can swing in all directions with the ball 503 as the fulcrum, so that the support surface of the adaptive plate 502 can fit the outer arc surface of the steel coil and adapt to the center of gravity distribution of the steel coil. Multiple fixing slots 406 are provided on the top surface of the base 1 along the sliding path of the side support plate 3. These fixing slots 406 are arranged in a straight line at preset intervals to provide locking positions of different widths. At the same time, the side support plate 3 is provided with fixing posts 405 that are adapted to the fixing slots 406. The fixing posts 405 can be inserted and removed through the through hole structure on the body of the side support plate 3. After the side support plate 3 is adjusted to a position that adapts to the width of the steel coil by the shrinking component 4, the fixing posts 405 are inserted downward and embedded into the fixing slots 406 at the corresponding positions on the base 1. The rigid contact between the side wall of the fixing post 405 and the inner wall of the fixing slot 406 restricts the freedom of the side support plate 3 in the horizontal direction, thereby realizing the physical locking between the side support plate 3 and the base 1. This matching structure effectively distributes the load borne by the gear 401 and the rack 402 when carrying heavy objects, significantly improving the overall structural rigidity and safety of the equipment. In addition, in order to provide a stable support environment for the power drive components, such as Figure 2As shown, the retraction assembly 4 also includes a support frame 403 fixed to the bottom of the base 1. The support frame 403 is constructed as a frame with an internal accommodating space. The motor 404 is installed inside the support frame 403. The support frame 403 not only provides a solid mounting base for the motor 404, ensuring that the motor output shaft and the gear 401 above maintain precise coaxiality, but also provides external protection for the motor 404, preventing foreign objects at the bottom from colliding with or damaging the motor. As a preferred embodiment, in order to prevent the steel coil from sliding relative to the support surface during handling and to avoid rigid force damage to the outer surface of the steel coil, an anti-slip strip 501 is fixed on the surface of the adapting plate 502 facing the center between the two side support plates 3. The anti-slip strip 501 is preferably made of wear-resistant rubber material. The anti-slip strip 501 is laid on the contact surface of the adapting plate 502. When the steel coil is placed, the anti-slip strip 501 is located between the steel coil and the adapting plate 502. The high coefficient of friction of the anti-slip strip 501 increases the static friction of the contact surface, while the elastic buffering performance of the rubber material absorbs the small vibrations during handling. As another preferred embodiment, in order to enable flexible movement and handling of the equipment on the workshop or warehouse floor, a number of sliding wheels 2 are fixedly connected to the bottom of the base 1. The sliding wheels 2 are evenly distributed around the bottom of the base 1 to provide stable support points. The sliding wheels 2 are constructed as heavy-duty industrial casters. Through the rolling cooperation between the sliding wheels 2 and the ground, the overall weight of the equipment is transferred to the ground, and the movement resistance of the equipment is changed from sliding friction to rolling friction, so that the operator can push or pull the base 1 to move the position.

[0015] Working principle: When it is necessary to use this equipment to handle steel coils of different specifications, the width is first adjusted to suit the needs. The operator first pulls the fixing column 405 out of the fixing groove 406 on the base 1 to release the physical lock of the opposite support plate 3. Then, the motor 404 installed inside the support frame 403 is started. The output shaft of the motor 404 rotates and drives the gear 401 to rotate. Since the gear 401 meshes with the racks 402 on both sides at the same time, the gear 401 drives the two racks 402 to make synchronous reverse linear movements along the width direction of the base 1, thereby driving the two side support plates 3 to move closer or further away from each other on the top surface of the base 1 until the distance between the two side support plates 3 is adjusted to a position suitable for the size of the steel coil to be handled. After the position of the side support plate 3 is adjusted, the operator passes the fixing column 405 through the side support plate 3 and inserts it into the corresponding fixing groove 406 on the base 1. The rigid cooperation between the fixing column 405 and the fixing groove 406 locks the side support plate 3 onto the base 1, preventing the side support plate 3 from sliding laterally when under force. Then, the steel coil is hoisted between the two side support plates 3. The outer circumference of the steel coil contacts the anti-slip strip 501 on the adapting plate 502. Under the action of the weight of the steel coil, the adapting plate 502 swings freely and adjusts its angle around the sphere 503 as the fulcrum until the supporting surface of the adapting plate 502 completely fits the outer curved surface of the steel coil and reaches a state of mechanical equilibrium. At this time, the anti-slip strip 501 increases the friction to prevent the steel coil from rolling. Finally, the steel coil is rolled on the ground by the sliding wheel 2 at the bottom of the base 1, realizing the stable handling of the steel coil.
