Description

Technical Field

[0001] The present invention relates to the technical field of stereoscopic warehouses, and in particular to a stereoscopic warehouse system for ultra-long and ultra-heavy steel coils and a method for using the system. Background Art

[0002] Steel coils (also known as coiled steel) are formed into coils by hot or cold pressing for easier storage, transportation, and processing. Common methods for storing steel coils are single-layer storage (application publication number CN119059189A, titled "A Circular-Surface Pocket Steel Coil Carriage") or multi-layer stacking (application publication number CN118062740A, titled "Method and Apparatus for Transporting Steel Coils"). Single-layer storage occupies a large space and is inefficient. While multi-layer stacking improves space utilization, it can easily cause deformation due to compression between coils and create surface defects such as scratches.

[0003] Currently, frame-type three-dimensional intelligent warehouses for steel coils have been gradually put into use (authorization announcement number CN107867625B, titled "Steel Coil Three-Dimensional Warehouse Hoist"). However, this type of warehouse requires a crane to transfer the steel coils and material frames. The volume and storage capacity of the steel coils are limited by the space between the crane and the material frames. The lifting operation efficiency and safety are low. During the lifting process, the cargo is poorly balanced and prone to shaking. Moreover, when the steel coils are too long or too heavy, the lifting method will cause the material frame to deform significantly under load, the equipment structure is bulky, and the processing and manufacturing costs are increased.

[0036] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0037] This specific embodiment provides an extra-long and extra-heavy steel coil three-dimensional warehouse system and a method for use, in order to solve the technical problems existing in the prior art that single-layer storage of steel coils occupies a large space, three-dimensional storage requires hoisting and placement, and has relatively low safety performance.

[0038] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the invention as set forth in the claims. Furthermore, the entire contents of the configurations shown in the following embodiments are not necessarily required to serve as solutions to the invention as set forth in the claims.

[0039] Reference Figures 1-8 The present invention provides a three-dimensional warehouse system for ultra-long and ultra-heavy steel coils, comprising:

[0040] The three-dimensional shelf 4 includes a three-dimensional frame 42, a third rail 41, and a first shelf saddle 43. The three-dimensional frame 42 is provided with at least two layers, which can make full use of the space of the high-rise. Each layer of the three-dimensional frame 42 is provided with multiple storage positions along the length direction to facilitate the placement of the steel coil 3. In order to facilitate the vehicles for placing the steel coil 3 to enter the storage position, each storage position is provided with a group of third rails 41. The length direction of the third rails 41 is perpendicular to the length direction of the three-dimensional frame 42, so that the vehicle supporting the steel coil 3 can enter the third rails 41. The first shelf saddle 43 is installed on both sides of the third rail 41 to support the steel coil 3. The side of the first shelf saddle 43 in contact with the steel coil 3 is provided with an inverted eight shape. The vehicle supporting the steel coil 3 places the steel coil 3 on the first shelf saddle 43 for storage.

[0041] The fixed shelf 5 is arranged at one end of the three-dimensional shelf 4 and is used to receive the steel coils 3. The number of fixed shelves 5 can be set as needed. The fixed shelf 5 includes a first frame 52, a set of fourth rails 53, and a second shelf saddle 51. The top of the first frame 52 is open, making it convenient to place the steel coils 3 directly onto the fixed shelf 5 from the top, or people can place them onto the second shelf saddle 51 via the fourth rail 53. The length direction of the fourth rail 53 is the same as that of the third rail 41 and is installed on the first frame 52. The second shelf saddle 51 is installed on both sides of the fourth rail 53. The side of the second shelf saddle 51 that contacts the steel coil 3 is configured in an inverted eight shape. The second shelf saddle 51 is used to support the steel coil 3.

[0042] The first track 2 has the same length direction as the three-dimensional shelves 4 and is arranged in the space between two adjacent three-dimensional shelves 4 to facilitate the transportation of the steel coils 3 to the three-dimensional shelves 4 on both sides of the first track 2;

[0043] The hydraulic lifting mother-and-child trolley 1 is used to remove the steel coil 3 from the fixed shelf 5 and transport it to the storage position on the three-dimensional shelf 4, wherein it includes a mother trolley walking mechanism 11, a first drive device, a hydraulic lifting structure 12, a mother trolley platform 13, a second track 14, a trolley body 19, a lifting mechanism 18, and an anti-slip and falling device 16. The mother trolley walking mechanism 11 travels on the first track 2, and the first drive device is arranged inside the mother trolley walking mechanism 11. In this way, the space inside the mother trolley walking mechanism 11 is fully and reasonably utilized, and the space occupied by the first drive device is greatly reduced. The hydraulic lifting structure 12 is installed on the mother trolley walking mechanism 11, and the mother trolley platform 13 is installed on the hydraulic lifting structure 12. The height of the hydraulic lifting structure 12 changes, so that the height of the mother trolley platform 13 changes, which is convenient for transporting the steel coil 3 to a higher position of the three-dimensional shelf 4. The second track 14 is installed on the mother vehicle platform 13 and is parallel to the third track 41. The second track 14 has the same width as the third track 41 and the fourth track 53. The trolley body 19 is installed on the second track 14 and can move between the second track 14, the third track 41 and the fourth track 53. The lifting mechanism 18 is installed on the trolley body 19 and can lift the steel coil 3 and transport the steel coil 3 at the same time. The anti-slip and fall-off device 16 is installed on the mother vehicle platform 13 and can confine the trolley body 19 on the mother vehicle platform 13, thereby preventing the trolley body 19 from accidentally moving on the mother vehicle platform 13.

[0044] Specifically, when the steel coil 3 needs to be taken out from the second shelf saddle 51 of the fixed shelf 5 and stored on the first shelf saddle 43 on the three-dimensional shelf 4, the hydraulic lifting trolley 1 moves to the position of the fixed shelf 5, lowers the height of the trolley body 19, and makes the fourth track 53 flush with the second track. The anti-skid device 16 unlocks the trolley body 19, making it convenient for the trolley body 19 to move to the fourth track. The lifting mechanism 18 on the trolley body 19 rises to lift the steel coil 3 on the fixed shelf 5, and the trolley body 19 moves to the second track 14. The anti-skid device 16 fastens the trolley body 19 to prevent the trolley body 19 from accidentally moving on the second track 14 when the mother trolley walking mechanism 11 is moving, thereby ensuring the safety of the trolley body 19 and the mother trolley. The walking mechanism 11 then moves to the storage position where the steel coil 3 needs to be placed, and the hydraulic lifting structure 12 of the hydraulic lifting trolley 1 raises or lowers the height of the trolley platform 13, so that the second track 14 on the trolley platform is flush with the third track on the three-dimensional shelf 4, making it convenient for the trolley body 19 to move to the third track 41, and the anti-slip device 16 is unlocked, releasing the trolley body 19, and the trolley body 19 moves to the third track 41. The lifting mechanism 18 lowers the height of the steel coil 3, so that the steel coil 3 falls on the first shelf saddle 43 on the three-dimensional shelf 4, and the first shelf saddle 43 supports the steel coil 3. The trolley body 19 moves to the trolley platform 13, and the anti-slip device locks the trolley body 19 to prevent the trolley body 19 from accidentally moving on the trolley platform.

[0045] With such an arrangement, the hydraulic lifting mother-and-child trolley lifts the steel coil 3 by lifting it from the bottom of the steel coil 3. There is no need to arrange a frame and transmission structure for bearing on the outside of the steel coil 3. Compared with chain and wire rope lifting, fork-type lifting and other methods, the structure and overall weight are simplified, the structure is more compact, space occupancy is saved, the overall power and energy consumption are lower, the production cost is reduced, maintenance is convenient, the load-bearing capacity is stronger, and the safety is higher. By utilizing the upper space to form a three-dimensional shelf 4, more steel coils 3 can be conveniently placed. At the same time, since the mother trolley platform is provided with an anti-slip and fall-off device 16, the safety and stability of the trolley body 19 during movement are guaranteed. In addition, the lifting device adopts a hydraulic system. Compared with the cylinder or electric cylinder drive method, the hydraulic system has a larger power output, is suitable for heavy-load conditions, and can lift overweight steel coils 3.

[0046] To further optimize the solution, in order to facilitate the smooth movement of the sub-trolley body 19 from the second track 14 to the third track 41 or the fourth track 53, anti-settling devices 15 are provided at both ends of the mother vehicle platform 13. The anti-settling devices 15 can be fixed on the three-dimensional shelf 4 or the fixed shelf 5 to establish connectivity between the mother vehicle platform 13 and the three-dimensional shelf 4 or the fixed shelf 5, so that the mother vehicle platform 13 and the three-dimensional shelf 4 or the fixed shelf 5 are combined into an integrated structure to avoid the mother vehicle platform 13 from tipping over or settling, thereby ensuring the safety of the sub-trolley body 19 during operation.

[0047] Specifically, the anti-settling device 15 can be a hydraulic telescopic rod or a rack rod or a second hook. When the anti-settling device is a hydraulic telescopic rod or a rack rod, a connection port is provided on the side of the three-dimensional shelf 4 close to the hydraulic lifting trolley 1 for the rack rod or the hydraulic telescopic rod to be inserted. When the anti-settling device 15 is set to a rack rod, the third driving device of the anti-settling device is provided with a gear, and the rotation of the gear drives the rack rod to extend or retract, thereby connecting the three-dimensional shelf 4 or the fixed shelf 5 to the mother vehicle platform 13. However, the end connected to the fixed shelf 5 or the three-dimensional shelf 4 is set to a smooth circumferential surface; when the anti-settling device is set to a hydraulic telescopic rod, it is only necessary to drive the hydraulic system; when the anti-settling device is a second hook, the second hook is rotatably mounted on the mother vehicle platform 13, and the third driving device of the anti-settling device drives the second hook to be hung on the three-dimensional shelf 4 or the fixed shelf 5, which can also make the mother vehicle platform 13 and the three-dimensional shelf 4 or the fixed shelf 5 combined into one. However, the anti-settling device 15 is not limited to these three situations. As long as the sub-vehicle body 19 moves between the second rail 14 and the third rail 41 or the second rail 14 and the fourth rail 53, the three-dimensional shelf 4 and the mother vehicle platform 13 can be combined together.

[0048] To further optimize the solution, in order to enable the steel coil 3 to be placed firmly on the lifting mechanism 18, anti-overturning devices 17 are provided on both sides of the mother vehicle platform 13, and the contact surface between the anti-overturning device 17 and the steel coil 3 is set as an inclined surface. The steel coil 3 is not only supported by the lifting mechanism 18, but also by the anti-overturning device 17, which can ensure the stability of the steel coil 3 during transportation.

[0049] Specifically, the anti-overturning device 17 includes a second hydraulic rod 171 and a clamping plate 172. The clamping plate 172 is mounted at one end of the second hydraulic rod 171, which is tilted and mounted on the carrier platform 13. This allows the height of the clamping plate 172 to be adjusted according to the different steel coils 3, allowing the clamping plate 172 to contact steel coils 3 of different specifications. In addition, to ensure the stability of the clamping plate 172, the clamping plate 172 can be hinged to the carrier platform.

[0050] To further optimize the solution, the anti-slip and fall-off device 16 includes a first rotatable hook 161 and a first through hole 162 arranged on the sub-trolley body 19. The first hook 161 rotates under the action of the first hydraulic rod or the fourth driving device, that is, when the first hydraulic rod is extended, the first hook 161 can rotate under the drive of the first hydraulic rod, and the first hook 161 is passed through the first through hole 162 and buckled on the sub-trolley body 19 to ensure the stability of the sub-trolley body 19 on the mother vehicle platform.

[0051] To further optimize the solution, in order to facilitate the hydraulic lifting trolley to obtain the current position and travel distance, a laser rangefinder or barcode sensor is provided on the hydraulic lifting trolley 1. The laser rangefinder or barcode sensor is electrically connected to the first control system of the hydraulic lifting trolley 1 to measure the position of the hydraulic lifting trolley 1, thereby facilitating automation.

[0052] Further optimization of the scheme by Figure 3 It can be seen that the hydraulic lifting structure 12 includes a third hydraulic rod 122 and a hinged support frame 121. When the third hydraulic rod 122 is extended, the height of the support frame 121 increases. When the third hydraulic rod 122 is retracted, the height of the support frame 121 decreases. In this way, lifting the extra-long and extra-heavy steel coil 3 from below has better safety and stability.

[0053] This application document also provides a method for using an ultra-long and ultra-heavy steel coil three-dimensional warehouse system, which is applicable to any of the above ultra-long and ultra-heavy steel coil three-dimensional warehouse systems, and the method includes:

[0054] S1. The hydraulic lifting trolley 1 receives the command to retrieve the steel coil 3 and moves to the position of the fixed shelf 5. During operation, the controller of the hydraulic lifting trolley 1 uses a laser rangefinder or barcode sensor to detect the current position of the hydraulic lifting trolley 1 in real time. When the second track 14 on the hydraulic lifting trolley 1 is aligned with the fourth track 53, the trolley travel mechanism 11 stops moving;

[0055] After the hydraulic lifting trolley 1 moves into place, the anti-settling device 15 extends from the mother trolley platform 13 and is connected to the fixed shelf 5, so that the mother trolley platform 13 and the fixed shelf 5 are connected as a whole, the anti-slip and fall-off device 16 releases the trolley body 19, the trolley body 19 moves to the fourth track 53, the lifting mechanism 18 lifts the steel coil 3, and the steel coil 3 is separated from the second shelf saddle 51 on the fixed shelf 5, the trolley body 19 drives the steel coil 3 back to the mother trolley platform 13, the anti-slip and fall-off device 16 locks the trolley body 19, and the anti-overturning device 17 clamps the steel coil 3 from both sides, and the anti-settling device 15 retracts from the fixed shelf 5 into the mother trolley platform 13 and separates from the fixed shelf 5. The second control system of the trolley body 19 receives the information of the steel coil 3, analyzes and determines the target position coordinates of the three-dimensional shelf 4, and sends it to the first control system of the mother trolley walking mechanism 11;

[0056] S3. The hydraulic lifting carrier 1 moves the steel coil 3 to the target position of the three-dimensional shelf 4. The first control system controls the hydraulic lifting structure 12 to raise and lower the carrier platform 13 to the target height. Simultaneously, the anti-overturning device 17 releases the steel coil 3 from the clamped state. The anti-settling device 15 extends from the carrier platform 13 and connects to the three-dimensional shelf 4.

[0057] S4. Carriage 19 moves from second track 14 to third track 41, and the lifting mechanism descends, placing coil 3 on first shelf saddle 43. The warehouse server receives information about coil 3. The primary purpose of this information exchange is to bind the coil 3's information to its location and to perform other tasks, such as data archiving.

[0058] S5. The sub-carriage body 19 returns to the mother car platform 13, the anti-slip and fall-off device 16 fixes the sub-carriage body 19, the anti-settling device 15 retracts from the three-dimensional shelf 4 to the inside of the mother car platform 13, and is separated from the three-dimensional shelf 4. The hydraulic lifting structure 12 drives the mother car platform 13 to lower its height.

[0059] With this arrangement, since the lifting mechanism of the hydraulic lifting trolley is driven by hydraulics, compared with pneumatic and electric methods, it has a simple structure when overloaded, greater power output, and lower energy consumption of the entire machine.

[0060] The hydraulic lifting mother-and-child trolley 1 is provided with an anti-settling device 15, which ensures that the second track 14 and the track on the three-dimensional shelf 4 or the fixed shelf 5 are aligned throughout the process of storing and retrieving the steel coil 3, and at the same time prevents the overall center of gravity of the hydraulic lifting mother-and-child trolley 1 from changing during the operation of the trolley body 19 along its second track 14, causing the trolley to tilt or sink, thereby increasing the safety and stability of storing and retrieving the steel coil 3. The trolley is composed of a trolley walking mechanism 11, a first drive device, a hydraulic lifting structure, a trolley platform 13, and a second track 14.

[0061] The hydraulic lifting trolley is provided with an anti-slip and falling device 16, which is used to clamp and fix the trolley body 19 after the trolley stops inside the mother car, so as to prevent the trolley body 19 from moving laterally or even sliding off the second track 14 due to the shaking of the steel coil 3 during the operation of the mother car.

[0062] The hydraulic lifting trolley is provided with an anti-overturning device 17 to prevent the steel coil 3 from overturning or falling due to shaking during the horizontal movement of the trolley.

[0063] The hydraulic lifting trolley lifts the steel coil 3 by lifting it from the bottom of the steel coil 3. There is no need to arrange a load-bearing frame and transmission structure on the outside of the steel coil 3. Compared with chain and wire rope lifting, fork-type lifting and other methods, it simplifies the structure and overall weight, has a more compact structure, saves space, has lower overall power and energy consumption, reduces production costs, facilitates maintenance, has a stronger load-bearing capacity and is safer.

[0064] The present application proposes a structure of three-dimensional shelves 4 and fixed shelves 5 for a three-dimensional warehouse for extra-long and extra-heavy steel coils. The structure is simple, stable and reliable, and can cooperate with the hydraulic lifting trolley 1 to realize convenient storage of extra-long and extra-heavy steel coils 3. It is not only suitable for extra-long and extra-heavy steel coils 3, but also for steel coils 3 of conventional specifications, with a wider range of applications and stronger versatility.
