Description

Technical Field

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

[0002] A steel coil (also known as a rolled steel) is a product formed by hot pressing or cold pressing steel into a coil shape for convenient storage, transportation, and processing of steel. During the storage process of steel coils, common methods include single-layer storage (application publication number CN119059189A, titled "An arc-surface steel coil-carrying mother and son vehicle") or multi-layer stacking storage of steel coils (application publication number CN118062740A, titled "Method and device for handling steel coils"). Single-layer storage occupies a large amount of space and has low space utilization; although multi-layer stacking storage of steel coils improves space utilization, the steel coils are easily deformed due to mutual extrusion, and defects such as scratches are easily generated on the surface of the steel coils.

[0003] Currently, frame-type stereoscopic intelligent warehouses for steel coils have been gradually put into use (authorization announcement number CN107867625B, titled "Stereoscopic warehouse spreader for steel coils"), but such stereoscopic warehouses require a crane to transfer steel coils and material frames. The volume of steel coils and the storage capacity are restricted by the space of the crane and the material frame. The hoisting operation efficiency and safety are relatively low. During the hoisting process, the balance of the goods is poor and it is easy to shake. Moreover, when the length of the steel coil is extra-long and the weight is overweight, the hoisting method will cause a large amount of deformation of the material frame under load, the equipment structure is bulky, and the processing and manufacturing cost increases.

[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0019] This specific implementation mode provides an ultra-long and overweight steel coil stereoscopic warehouse system and a using method thereof to solve the technical problems existing in the prior art that the single-layer storage of steel coils occupies a large space, and the stereoscopic storage requires hoisting and placing, and the safety performance is relatively low.

[0020] Hereinafter, the embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not limit the content of the invention described in the claims in any way. In addition, all the contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the invention described in the claims.

[0021] Referring to Figures 1-8 , the present invention provides an ultra-long and overweight steel coil stereoscopic warehouse system, including: A stereoscopic shelf 4, the stereoscopic shelf 4 includes a stereoscopic frame 42, a third track 41, and a first shelf saddle 43. The stereoscopic frame 42 has at least two layers, which can make full use of the space on the upper floors. Each layer of the stereoscopic frame 42 is provided with a plurality of storage positions along the length direction to facilitate the placement of the steel coil 3. In order to facilitate the vehicle for placing the steel coil 3 to enter the storage position, a set of third tracks 41 are provided on each storage position. The length direction of the third track 41 is perpendicular to the length direction of the stereoscopic frame 42, so that the vehicle supporting the steel coil 3 can enter the third track 41. The first shelf saddle 43 is installed on both sides of the third track 41 for supporting the steel coil 3. One side of the first shelf saddle 43 in contact with the steel coil 3 is provided with an inverted V shape. The vehicle supporting the steel coil 3 places the steel coil 3 on the first shelf saddle 43 for storage.

[0022] Fixed shelf 5 is provided at one end of the three-dimensional shelf 4 and is used to receive the steel coil 3. The number of fixed shelves 5 can be set as required. The fixed shelf 5 includes a first frame 52, a set of fourth tracks 53, and a second shelf saddle 51. The top of the first frame 52 is open, which facilitates directly placing the steel coil 3 on the fixed shelf 5 from the top, or people can place it on the second shelf saddle 51 through the fourth track 53. The length direction of the fourth track 53 is the same as that of the third track 41 and is installed on the first frame 52. The second shelf saddle 51 is installed on both sides of the fourth track 53. One side of the second shelf saddle 51 in contact with the steel coil 3 is set in an inverted V shape, and the second shelf saddle 51 is used to support the steel coil 3; The first track 2 has the same length direction as the three-dimensional shelf 4 and is arranged in the space between two adjacent three-dimensional shelves 4, which facilitates transporting the steel coil 3 to the three-dimensional shelves 4 on both sides of the first track 2; The hydraulic lifting mother-and-child vehicle 1 is used to remove the steel coil 3 on the fixed shelf 5 and transport it to the storage position on the three-dimensional shelf 4. It includes a mother vehicle traveling mechanism 11, a first driving device, a hydraulic lifting structure 12, a mother vehicle platform 13, a second track 14, a child vehicle body 19, a lifting mechanism 18, and an anti-slip and anti-falling device 16. The mother vehicle traveling mechanism 11 travels on the first track 2, and the first driving device is arranged inside the mother vehicle traveling mechanism 11, so as to make full and reasonable use of the space inside the mother vehicle traveling mechanism 11 and greatly reduce the occupied space of the first driving device. The hydraulic lifting structure 12 is installed on the mother vehicle traveling mechanism 11, and the mother vehicle platform 13 is installed on the hydraulic lifting structure 12. The height of the hydraulic lifting structure 12 changes to cause the height of the mother vehicle platform 13 to change, which facilitates transporting the steel coil 3 to a higher position on 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 widths of the second track 14, the third track 41, and the fourth track 53 are equal. The child vehicle body 19 is installed on the second track 14 and can travel between the second track 14, the third track 41, and the fourth track 53. The lifting mechanism 18 is installed on the child vehicle body 19 and can lift and transport the steel coil 3 at the same time. The anti-slip and anti-falling device 16 is installed on the mother vehicle platform 13 and can limit the child vehicle body 19 on the mother vehicle platform 13, thus preventing the child vehicle body 19 from having accidental movement on the mother vehicle platform 13.

[0023] Specifically, when it is necessary to remove the steel coil 3 from the second rack saddle 51 of the fixed rack 5 and store it on the first rack saddle 43 of the three-dimensional rack 4, the hydraulic lifting double car 1 moves to the position of the fixed rack 5, lowers the height of the car body 19 of the sub-car, makes the fourth track 53 flush with the second track, and the anti-slip and anti-drop device 16 unlocks the car body 19 of the sub-car, facilitating the movement of the car body 19 of the sub-car onto the fourth track. The lifting mechanism 18 on the car body 19 of the sub-car rises to lift the steel coil 3 on the fixed rack 5. The car body 19 of the sub-car moves onto the second track 14, and the anti-slip and anti-drop device 16 fastens the car body 19 of the sub-car to prevent the car body 19 of the sub-car from accidentally moving on the second track 14 when the walking mechanism 11 of the mother car is moving, ensuring the safety of the car body 19 of the sub-car. Subsequently, the walking mechanism 11 of the mother car moves to the storage position where the steel coil 3 needs to be placed, and the hydraulic lifting structure 12 of the hydraulic lifting double car 1 raises or lowers the height of the mother car platform 13, so that the second track 14 on the mother car platform is flush with the third track on the three-dimensional rack 4, facilitating the movement of the car body 19 of the sub-car onto the third track 41. And the anti-slip and anti-drop device 16 unlocks and releases the car body 19 of the sub-car. The car body 19 of the sub-car moves onto the third track 41, and the lifting mechanism 18 lowers the height of the steel coil 3, making the steel coil 3 fall onto the first rack saddle 43 on the three-dimensional rack 4. The first rack saddle 43 supports the steel coil 3. The car body 19 of the sub-car moves onto the mother car platform 13, and the anti-slip and anti-drop device locks the car body 19 of the sub-car to avoid accidental movement of the car body 19 of the sub-car on the mother car platform.

[0024] With such a setting, the hydraulic lifting double car lifts the steel coil 3 by lifting it from below the steel coil 3, without the need to arrange a load-bearing frame and a transmission structure outside the steel coil 3. Compared with methods such as chain and wire rope hoisting and forklift lifting, the structure and the overall weight are simplified, the structure is more compact, the space occupation is saved, the overall power and energy consumption are lower, the production and manufacturing cost is reduced, it is convenient for maintenance, the load-bearing capacity is stronger, and the safety is higher. By using the upper space to form the three-dimensional rack 4, more steel coils 3 can be conveniently placed. At the same time, since the anti-slip and anti-drop device 16 is arranged on the mother car platform, the safety and stability of the car body 19 of the sub-car during the movement process are ensured. In addition, the lifting device adopts a hydraulic system. Compared with the driving methods of cylinders or electric cylinders, the hydraulic system has a larger power output, is suitable for heavy-duty working conditions, and can lift the overweight steel coil 3.

[0025] For a further optimized solution, in order to facilitate the smooth movement of the sub-vehicle body 19 from the second track 14 to the third track 41 or the fourth track 53, anti-settlement devices 15 are provided at both ends of the mother vehicle platform 13. The anti-settlement devices 15 can be fixed on the three-dimensional shelf 4 or the fixed shelf 5 to establish the connectivity between the mother vehicle platform 13 and the three-dimensional shelf 4 or the fixed shelf 5, combining the mother vehicle platform 13 with the three-dimensional shelf 4 or the fixed shelf 5 into an integrated structure, avoiding the tipping or settlement of the mother vehicle platform 13 and ensuring the safety of the sub-vehicle body 19 during operation.

[0026] Specifically, the anti-settlement device 15 can be a hydraulic telescopic rod or a rack rod or a second hook. When the anti-settlement 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 mother-daughter vehicle 1 for the rack rod or the hydraulic telescopic rod to be inserted. When the anti-settlement device 15 is set as a rack rod, a gear is provided on the third driving device of the anti-settlement device, 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 with the mother vehicle platform 13. However, the end connected to the fixed shelf 5 or the three-dimensional shelf 4 is set as a smooth circumferential surface; when the anti-settlement device is set as a hydraulic telescopic rod, only the hydraulic system needs to be driven; when the anti-settlement device is a second hook, the second hook is rotatably installed on the mother vehicle platform 13, and the third driving device of the anti-settlement device drives the second hook to be hung on the three-dimensional shelf 4 or the fixed shelf 5, which can also combine the mother vehicle platform 13 with the three-dimensional shelf 4 or the fixed shelf 5 into an integrated body. However, the anti-settlement device 15 is not limited to these three cases, as long as the three-dimensional shelf 4 is combined with the mother vehicle platform 13 when the sub-vehicle body 19 moves between the second track 14 and the third track 41 or between the second track 14 and the fourth track 53.

[0027] For a further optimized solution, in order to enable the steel coil 3 to be stably placed on the lifting mechanism 18, anti-overturning devices 17 are provided on both sides of the mother vehicle platform 13. 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 supported not only 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.

[0028] Specifically, the anti-overturning device 17 includes a second hydraulic rod 171 and a clamping plate 172. The clamping plate 172 is installed at one end of the second hydraulic rod 171. The second hydraulic rod 171 is inclinedly installed on the mother vehicle platform 13, which can adjust the height of the clamping plate 172 according to different steel coils 3, facilitating the contact between the clamping plate 172 and steel coils 3 of different specifications. In addition, in order to ensure the stability of the clamping plate 172, the clamping plate 172 can be hinged on the mother vehicle platform.

[0029] A further optimized solution is provided, in which 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.

[0030] To further optimize the solution, in order to facilitate the hydraulic lifting mother-and-child vehicle to obtain the current position and the travel distance, a laser rangefinder or a barcode sensor is arranged on the hydraulic lifting mother-and-child vehicle 1. The laser rangefinder or the barcode sensor is electrically connected to the first control system of the hydraulic lifting mother-and-child vehicle 1 to measure the position of the hydraulic lifting mother-and-child vehicle 1, so as to facilitate automation.

[0031] To further optimize the solution, 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.

[0032] This application document also provides a method for using an ultra-long and ultra-heavy steel coil stereoscopic warehouse system, which is applied to any of the above ultra-long and ultra-heavy steel coil stereoscopic warehouse systems, and the method includes: S1. The hydraulic lifting trolley 1 receives the instruction to take the steel coil 3 and moves to the position of the fixed shelf 5. During the operation, the controller of the hydraulic lifting trolley 1 detects the current position of the hydraulic lifting trolley 1 in real time through a laser rangefinder or a barcode sensor. 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; S2. After the hydraulic lifting mother-child trolley 1 moves into position, 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-skid 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, 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-skid and fall-off device 16 locks the trolley body 19, the anti-overturning device 17 clamps the steel coil 3 from both sides, the anti-settling device 15 retracts from the fixed shelf 5 into the mother trolley platform 13, and is separated 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; S3. The hydraulic lifting mother-daughter vehicle 1 drives the steel coil 3 to move to the target position of the three-dimensional storage rack 4. The first control system controls the lifting of the hydraulic lifting structure 12 to lift the mother vehicle platform 13 to the target height. At the same time, the anti-overturning device 17 releases the steel coil 3 from the clamped state, and the anti-settlement device 15 extends from the mother vehicle platform 13 to connect with the three-dimensional storage rack 4; S4. The daughter vehicle body 19 moves from the second track 14 to the third track 41, and the lifting mechanism descends to place the steel coil 3 on the first rack saddle 43. The server of the three-dimensional warehouse receives the information of the steel coil 3. That is, the main purpose of the information interaction here is to bind the various information of the steel coil 3 with the information of the storage location where it is placed, as well as the processing of similar data archiving, etc.; S5. The daughter vehicle body 19 returns to the mother vehicle platform 13, and the anti-slip and anti-drop device 16 fixes the daughter vehicle body 19. The anti-settlement device 15 retracts from the three-dimensional storage rack 4 into the interior of the mother vehicle platform 13 and separates from the three-dimensional storage rack 4. The hydraulic lifting structure 12 drives the mother vehicle platform 13 to lower in height.

[0033] With such a setting, since the lifting mechanism of the hydraulic lifting mother-daughter vehicle is hydraulically driven, compared with pneumatic and electric methods, the structure is simple under heavy loads, the power output is greater, and the overall energy consumption of the whole machine is lower.

[0034] The hydraulic lifting mother-daughter vehicle 1 is provided with an anti-settlement device 15, which ensures that the second track 14 and the three-dimensional storage rack 4 or the track on the fixed storage rack 5 are fully aligned during the process of storing and retrieving the steel coil 3. At the same time, it prevents the overall center of gravity of the hydraulic lifting mother-daughter vehicle 1 from changing during the operation of the daughter vehicle body 19 along its second track 14, resulting in the mother vehicle tilting or settling, increasing the safety and stability of storing and retrieving the steel coil 3. The mother vehicle is composed of a mother vehicle traveling mechanism 11, a first driving device, a hydraulic lifting structure, a mother vehicle platform 13, and a second track 14.

[0035] The hydraulic lifting mother-daughter vehicle is provided with an anti-slip and anti-drop device 16, which is used to clamp and fix the daughter vehicle body 19 after the daughter vehicle stops stably inside the mother vehicle, avoiding the situation that the daughter vehicle body 19 moves horizontally or even slides out of the second track 14 due to the shaking of the steel coil 3 or other reasons during the operation of the mother vehicle.

[0036] The hydraulic lifting mother-daughter vehicle is provided with an anti-overturning device 17 to prevent the steel coil 3 from overturning or falling due to shaking or the like during the horizontal movement of the mother-daughter vehicle.

[0037] The hydraulic lifting mother-daughter vehicle lifts the steel coil 3 by lifting it from below the steel coil 3, and does not require a frame and a transmission structure for bearing to be arranged outside the steel coil 3. Compared with methods such as chain and wire rope lifting and forklift lifting, the structure and the overall weight are simplified, the structure is more compact, the space occupation is saved, the overall power and energy consumption are lower, the production and manufacturing cost is reduced, it is convenient for maintenance, the bearing capacity is stronger, and the safety is higher.

[0038] The three-dimensional shelf 4 and the fixed shelf 5 structure proposed in this application for the three-dimensional warehouse of extra-long and extra-heavy steel coils have a simple structure, are stable and reliable, and can cooperate with the hydraulic lifting mother and child vehicle 1 to achieve convenient storage of extra-long and extra-heavy steel coils 3; it is not only applicable to extra-long and extra-heavy steel coils 3, but also applicable to steel coils 3 of conventional specifications, with a wider application range and stronger versatility.
