Description

Technical Field

[0001] This invention relates to the field of stacker crane technology, specifically to a stacker crane for warehousing and logistics systems and its usage method. Background Technology

[0002] In modern logistics systems, automated storage and retrieval systems (AS / RS) have become a rapidly developing main force. An AS / RS is a warehouse system that utilizes multiple layers of space to store goods. It mainly consists of racks, input systems, output systems, and storage and retrieval systems. Among them, stacker cranes are important equipment for the entry and exit of goods in AS / RS.

[0003] In some existing stacker cranes, when moving goods between two racks, the forks typically need to extend into the rack to move the goods onto the crane's platform. This process involves multiple stages, including fork extension, goods grabbing, and platform raising and lowering. However, in practice, when the platform is raised to a high position and the forks need to be extended, the forks are suspended in the air. This design presents a certain stability risk. Specifically, when the forks are suspended, they are susceptible to gravity and external forces, causing them to tilt or sway, thus affecting the safety of the goods. Furthermore, the suspended state can lead to unstable contact between the forks and the goods, increasing the risk of goods falling. This not only threatens the safety of warehousing operations but may also lead to equipment damage and goods loss, ultimately impacting overall work efficiency. Summary of the Invention

[0012] Preferably, the end of the connecting rod away from the lifting plate is fixedly installed with the lower pressure plate, the connecting plate is fixedly installed with the lifting slider, the end of the connecting moving rod away from the upper connecting frame is rotatably connected with the lower connecting frame, the connecting moving rod is inclined, the limiting sliding rod is slidably installed with the limiting sliding groove, the end of the mounting vertical rod away from the connecting horizontal plate passes through the adjusting plate and the lifting plate in sequence, and the mounting vertical rod is slidably installed with the adjusting plate and the lifting plate.

[0013] Preferably, the auxiliary component includes an auxiliary groove formed on the support platform, an auxiliary slide groove is formed inside the auxiliary groove, an auxiliary slide rod is slidably installed in the auxiliary slide groove, an auxiliary connecting rod is fixedly installed on the auxiliary slide rod, and a U-shaped frame plate is fixedly installed on the inner side of the auxiliary top plate.

[0014] Preferably, the auxiliary connecting rod is fixedly connected to the center of the auxiliary slide rod, and the end of the auxiliary connecting rod away from the auxiliary connecting rod is rotatably connected to the U-shaped frame plate. The auxiliary connecting rod is arranged at an angle, and the U-shaped frame plate is located inside the limiting slide rod.

[0015] Preferably, a U-shaped fixed frame is fixedly installed on the lower end face of the lifting slider, a stabilizing connecting rod is rotatably installed inside the U-shaped fixed frame, an auxiliary sliding column is fixedly installed on the side end face of the auxiliary connecting rod, and an auxiliary transverse groove is opened on the side end face of the fork plate.

[0016] Preferably, the auxiliary link is located on the outside of the fork plate, and the end of the auxiliary slide bar away from the auxiliary link extends into the interior of the auxiliary slide groove, and the auxiliary slide bar and the auxiliary slide groove are slidably installed.

[0017] A method for using a stacker crane in a warehousing and logistics system, based on the above-described method, includes the following steps:

[0018] S1. Move the rack slide to the designated shelf position via the first slide rail, then raise the support platform to the appropriate position via the lifting slide rail, and move the fork to the position of the goods via the second slide rail, and use the fork to remove the goods from the shelf.

[0019] S2. When the forklift moves horizontally to the shelf position, the drive motor is started synchronously. The drive motor drives the drive rod to rotate. The drive rod will drive the lifting slider on the adjustment plate to descend through the second thread. The upper connecting frame on the lifting slider cooperates with the connecting rod, the connecting rod cooperates with the lower connecting frame on the auxiliary top plate, and the limit slide rod limits the movement of the auxiliary top plate. This allows the auxiliary top plate to move outward synchronously with the auxiliary slide rail. The stability of the forklift is ensured when it moves horizontally by the top fixed contact between the auxiliary top plate and the shelves on both sides.

[0020] S3. Simultaneously, when the drive rod rotates, it will drive the lifting plate to rise through the first thread. When the goods are moved from the shelf to the carrying platform through the fork plate, the auxiliary top plate will return to its original position through the reversal of the drive rod. At the same time, the lifting plate will drive the lower pressure plate to fall through the connecting rod, and the extension rod will drive the extension pressure plate to fall. By using the cooperation of the extension pressure plate and the lower pressure plate, the downward pressure can be effectively applied to the goods on the fork plate, ensuring that the goods are in a stable state on the carrying platform during the change of position.

[0021] S4. When the lifting slider descends, the U-shaped fixed frame on the lifting slider will descend synchronously. The stabilizing link on the U-shaped fixed frame will tilt through the cooperation of the auxiliary sliding column and the auxiliary transverse groove. When the fork moves outward, the fork will be in a stable sliding state through the limiting of the auxiliary transverse groove and the auxiliary sliding column. At the same time, the limiting of the auxiliary sliding column and the end of the auxiliary transverse groove ensures that when the fork extends outside the bearing platform, the entire fork will be in a stable state through the pulling of the stabilizing link.

[0022] S5. When the auxiliary top plate moves outward from the support platform, the auxiliary top plate will drive the two auxiliary connecting rods to move synchronously through the U-shaped frame plate. The auxiliary connecting rods will move inward synchronously through the limiting of the auxiliary sliding rod and the auxiliary sliding groove. The limiting and support of the auxiliary connecting rods ensure the stability of the auxiliary top plate and improve the stability of the fork plate when moving horizontally.

[0023] This invention provides a stacker crane for a warehousing and logistics system and its usage method. Compared with the prior art, it has the following advantages:

[0024] 1. In this invention, when the forklift moves horizontally to the position of the shelf, the drive motor is started simultaneously. The drive motor drives the drive rod to rotate, and the drive rod drives the lifting slider on the adjustment plate to descend through the second thread. The upper connecting frame on the lifting slider cooperates with the connecting rod, the connecting rod cooperates with the lower connecting frame on the auxiliary top plate, and the limiting slide rod limits the movement of the auxiliary top plate. This allows the auxiliary top plate to move outward synchronously with the auxiliary slide rail. The stability of the forklift during horizontal movement is ensured by the top-fixed contact between the auxiliary top plate and the shelves on both sides.

[0025] 2. In this invention, when the lifting slider descends, the U-shaped fixed frame on the lifting slider will descend synchronously. The stabilizing link on the U-shaped fixed frame will tilt through the cooperation of the auxiliary sliding column and the auxiliary transverse groove. When the fork plate moves outward, the fork plate will be limited by the auxiliary transverse groove and the auxiliary sliding column, thus being in a stable sliding state. At the same time, the auxiliary sliding column and the end of the auxiliary transverse groove are used to limit the fork plate, ensuring that when the fork plate extends outside the bearing platform, the entire fork plate will be in a stable state through the pull of the stabilizing link.

[0026] 3. In this invention, when the auxiliary top plate moves outward from the support platform, the auxiliary top plate will drive the two auxiliary connecting rods to move synchronously through the U-shaped frame plate. The auxiliary connecting rods will move inward synchronously through the limiting of the auxiliary sliding rod and the auxiliary sliding groove. The limiting and support of the auxiliary connecting rods ensure the stability of the auxiliary top plate and improve the stability of the fork plate when moving horizontally.

[0027] 4. In this invention, when the drive rod rotates, it drives the lifting plate to rise through the first thread. When the goods are moved from the shelf to the carrying platform through the fork plate, the auxiliary top plate is restored to its original position by reversing the drive rod. At the same time, the lifting plate will drive the lower pressure plate to fall through the connecting rod, and the extension rod will drive the extension pressure plate to fall. By utilizing the cooperation between the extension pressure plate and the lower pressure plate, the downward pressure can be effectively applied to the goods on the fork plate, ensuring that the goods remain stable on the carrying platform during the change of position.

The motion structure principles of the first slide rails 1 and frame slide 2, the second slide rails 5 and fork plates 6, and the lifting slide rails 3 and support platform 4 are all technologies well known to those skilled in the art and will not be described in detail here.

[0039] The drive assembly includes a drive motor 13 fixedly mounted on the connecting horizontal plate 8. A drive rod 14 is fixedly mounted on the output end of the drive motor 13. The drive rod 14 has a first thread 15 and a second thread 16. The drive rod 14 is movably mounted on the lifting plate 17 through the first thread 15. A connecting rod 18 is fixedly mounted on the lower end face of the lifting plate 17. An extension rod 19 is fixedly mounted on the outer side of the lower pressure plate 9. An extension pressure plate 20 is fixedly mounted on the extension rod 19. An adjusting plate 21 is movably mounted on the drive rod 14 through the second thread 16. A connecting plate 22 is fixedly mounted on the lower end face of the adjusting plate 21. An upper connecting frame 23 is fixedly mounted on the side end face of the lower end face of the lifting slider 10. A lower connecting frame 24 is fixedly mounted on the upper end face of the auxiliary top plate 11. A connecting rod 25 is rotatably mounted on the upper connecting frame 23. A limit sliding rod 26 is fixedly mounted on the side end face of the auxiliary top plate 11. A limit sliding groove 27 is opened on the side end face of the bearing platform 4. A mounting vertical rod 28 is fixedly installed. The end of the connecting rod 18 away from the lifting plate 17 is fixedly installed with the lower pressure plate 9. The connecting plate 22 is fixedly installed with the lifting slider 10. The end of the connecting moving rod 25 away from the upper connecting frame 23 is rotatably connected with the lower connecting frame 24. The connecting moving rod 25 is arranged at an angle. The limiting slide rod 26 is slidably installed with the limiting slide groove 27. The end of the mounting vertical rod 28 away from the connecting horizontal plate 8 passes through the adjusting plate 21 and the lifting plate 17 in sequence. The mounting vertical rod 28 is slidably installed with the adjusting plate 21 and the lifting plate 17. The top of the connecting vertical rod 7 passes through the lifting slider 10 and is slidably installed with the lifting slider 10. The position of the connecting horizontal plate 8 is above the lifting slider 10. There is a certain distance between the extension pressure plate 20 and the lower pressure plate 9. This distance ensures that the distance of the lower pressure plate 9 can be controlled during the lifting process. And the positioning of the mounting vertical rod 28 ensures the stability of the lower pressure plate 9 and the adjusting plate 21 during the lifting process.

[0040] In this embodiment, when the forklift plate 6 moves horizontally to the shelf position, the drive motor 13 is started synchronously. The drive motor 13 drives the drive rod 14 to rotate, and the drive rod 14 drives the lifting slider 10 on the adjusting plate 21 to descend through the second thread 16. The upper connecting frame 23 on the lifting slider 10 cooperates with the connecting rod 25, the connecting rod 25 cooperates with the lower connecting frame 24 on the auxiliary top plate 11, and the limiting slide rod 26 limits the movement of the auxiliary top plate 11. This causes the auxiliary top plate 11 to synchronously drive the auxiliary slide rail 12 to move outward. The auxiliary top plate 11 makes solid contact with the top of the shelves on both sides, ensuring the forklift... The stability of plate 6 during horizontal movement is ensured. Simultaneously, when the drive rod 14 rotates, it drives the lifting plate 17 to rise through the first thread 15. When the goods are moved from the shelf to the carrying platform 4 via the fork plate 6, the auxiliary top plate 11 returns to its original position through the reversal of the drive rod 14. At the same time, the lifting plate 17 drives the lower pressure plate 9 to descend through the connecting rod 18, and the extension rod 19 drives the extension pressure plate 20 to descend. By utilizing the cooperation between the extension pressure plate 20 and the lower pressure plate 9, downward pressure can be effectively applied to the goods on the fork plate 6, ensuring that the goods remain stable on the carrying platform 4 during position changes.

[0041] The auxiliary components include an auxiliary groove 29 formed on the support platform 4, an auxiliary slide groove 30 formed inside the auxiliary groove 29, an auxiliary slide rod 31 slidably installed in the auxiliary slide groove 30, an auxiliary connecting rod 32 fixedly installed on the auxiliary slide rod 31, a U-shaped frame plate 33 fixedly installed on the inner side of the auxiliary top plate 11, the auxiliary connecting rod 32 fixedly connected to the center of the auxiliary slide rod 31, the end of the auxiliary connecting rod 32 away from the auxiliary connecting rod 31 being rotatably connected to the U-shaped frame plate 33, the auxiliary connecting rod 32 being inclined, and the U-shaped frame plate 33 being positioned inside the limiting slide rod 26. The auxiliary slide rod 31 can rotate and move horizontally within the auxiliary slide groove 30, ensuring that the auxiliary connecting rod 32 can rotate during movement, and the initial positions of the U-shaped frame plate 33 and the auxiliary connecting rod 32 are within the auxiliary groove 29.

[0042] In this embodiment, when the lifting slider 10 descends, the U-shaped fixed frame 34 on the lifting slider 10 will descend synchronously. The stabilizing link 35 on the U-shaped fixed frame 34 will tilt through the cooperation of the auxiliary sliding column 36 and the auxiliary transverse groove 37. When the fork plate 6 moves outward, the fork plate 6 will be in a stable sliding state through the limitation of the auxiliary transverse groove 37 and the auxiliary sliding column 36. At the same time, the limitation of the slot end of the auxiliary sliding column 36 and the auxiliary transverse groove 37 ensures that when the fork plate 6 extends outside the bearing platform 4, the entire fork plate 6 will be in a stable state through the pull of the stabilizing link 35.

[0043] A U-shaped fixed frame 34 is fixedly installed on the lower end face of the lifting slider 10. A stabilizing link 35 is rotatably installed inside the U-shaped fixed frame 34. An auxiliary sliding column 36 is fixedly installed on the side end face of the auxiliary link 32. An auxiliary transverse groove 37 is opened on the side end face of the fork plate 6. The auxiliary link 32 is located on the outside of the fork plate 6. The end of the auxiliary sliding column 36 away from the auxiliary link 32 extends into the interior of the auxiliary sliding groove 30. The auxiliary sliding column 36 is slidably installed with the auxiliary sliding groove 30. The auxiliary column can rotate and slide within the auxiliary sliding groove 30 to ensure that the stabilizing link 35 can change from a vertical state to an inclined state.

[0044] In this embodiment, when the auxiliary top plate 11 moves outward from the support platform 4, the auxiliary top plate 11 will drive the two auxiliary connecting rods 32 to move synchronously through the U-shaped frame plate 33. The auxiliary connecting rods 32 will move inward synchronously through the limiting of the auxiliary sliding rod 31 and the auxiliary sliding groove 30. Through the limiting and support of the auxiliary connecting rods 32, the stability of the auxiliary top plate 11 is ensured, and the stability of the fork plate 6 during horizontal movement is improved.

[0045] A method for using a stacker crane in a warehousing and logistics system, based on the above-described method, includes the following steps:

[0046] S1. Move the rack slide 2 to the designated shelf position via the first slide rail 1, then raise the carrying platform 4 to the appropriate position via the lifting slide rail 3, and move the fork plate 6 to the position of the goods via the second slide rail 5. Use the fork plate 6 to remove the goods from the shelf.

[0047] S2. When the forklift plate 6 moves horizontally to the position of the shelf, the drive motor 13 is started synchronously. The drive motor 13 drives the drive rod 14 to rotate. The drive rod 14 will drive the lifting slider 10 on the adjusting plate 21 to descend through the second thread 16. The upper connecting frame 23 on the lifting slider 10 cooperates with the connecting rod 25, the connecting rod 25 cooperates with the lower connecting frame 24 on the auxiliary top plate 11, and the limiting slide rod 26 limits the movement of the auxiliary top plate 11. This allows the auxiliary slide rail 12 to move outward synchronously. The stability of the forklift plate 6 during horizontal movement is ensured by the top-fixed contact between the auxiliary top plate 11 and the shelves on both sides.

[0048] S3. When the lifting slider 10 descends, the U-shaped fixed frame 34 on the lifting slider 10 will descend synchronously. The stabilizing link 35 on the U-shaped fixed frame 34 will tilt through the cooperation of the auxiliary sliding column 36 and the auxiliary transverse groove 37. When the fork plate 6 moves outward, the fork plate 6 will be in a stable sliding state through the limiting of the auxiliary transverse groove 37 and the auxiliary sliding column 36. At the same time, the limiting of the slot end of the auxiliary sliding column 36 and the auxiliary transverse groove 37 ensures that when the fork plate 6 extends outside the bearing platform 4, the entire fork plate 6 will be in a stable state through the pulling of the stabilizing link 35.

[0049] S4. When the auxiliary top plate 11 moves outward from the support platform 4, the auxiliary top plate 11 will drive the two auxiliary connecting rods 32 to move synchronously through the U-shaped frame plate 33. The auxiliary connecting rods 32 will move inward synchronously through the limiting of the auxiliary sliding rod 31 and the auxiliary sliding groove 30. Through the limiting and support of the auxiliary connecting rods 32, the stability of the auxiliary top plate 11 is ensured, and the stability of the fork plate 6 is improved when moving horizontally.

[0050] S5. When the drive rod 14 rotates, it drives the lifting plate 17 to rise through the first thread 15. When the goods are moved from the shelf to the carrying platform 4 through the fork plate 6, the auxiliary top plate 11 is restored to its original position by the reversal of the drive rod 14. At the same time, the lifting plate 17 drives the lower pressure plate 9 to fall through the connecting rod 18, and the extension rod 19 drives the extension pressure plate 20 to fall. By using the cooperation of the extension pressure plate 20 and the lower pressure plate 9, the downward pressure can be effectively applied to the goods on the fork plate 6, ensuring that the goods are in a stable state on the carrying platform 4 during the position change process.

A method of using a stacker crane for a warehousing and logistics system, based on the stacker crane for a warehousing and logistics system according to any one of claims 1-9, characterized in that, Includes the following steps: S1. Move the rack slide (2) to the designated shelf position by the first slide rail (1), then raise the support platform (4) to the appropriate position by the lifting slide rail (3), and move the fork plate (6) to the position of the goods by the second slide rail (5). Use the fork plate (6) to remove the goods from the shelf. S2. When the fork plate (6) moves horizontally to the position of the shelf, the drive motor (13) is started synchronously. The drive motor (13) drives the drive rod (14) to rotate. The drive rod (14) will drive the lifting slider (10) on the adjusting plate (21) to descend through the second thread (16). The upper connecting frame (23) on the lifting slider (10) cooperates with the connecting rod (25), the connecting rod (25) cooperates with the lower connecting frame (24) on the auxiliary top plate (11), and the limiting slide rod (26) limits the movement of the limiting slide rod (26). This allows the auxiliary top plate (11) to drive the auxiliary slide rail (12) to move outward synchronously. Through the top contact between the auxiliary top plate (11) and the shelves on both sides, the stability of the fork plate (6) during horizontal movement is ensured. S3. At the same time, when the drive rod (14) rotates, it will drive the lifting plate (17) to rise through the first thread (15). When the goods are moved from the shelf to the carrying platform (4) through the fork plate (6), the auxiliary top plate (11) will return to its original position through the reversal of the drive rod (14). At the same time, the lifting plate (17) will drive the lower pressure plate (9) to fall through the connecting rod (18), and the extension rod (19) will drive the extension pressure plate (20) to fall. By utilizing the cooperation between the extension pressure plate (20) and the lower pressure plate (9), the downward pressure can be effectively applied to the goods on the fork plate (6), ensuring that the goods are in a stable state on the carrying platform (4) during the position change process. S4. When the lifting slider (10) descends, the U-shaped fixed frame (34) on the lifting slider (10) will descend synchronously. The stabilizing link (35) on the U-shaped fixed frame (34) will tilt through the cooperation of the auxiliary sliding column (36) and the auxiliary transverse groove (37). When the fork plate (6) moves outward, the fork plate (6) will be in a stable sliding state through the limiting of the auxiliary transverse groove (37) and the auxiliary sliding column (36). At the same time, by using the limiting of the slot end of the auxiliary sliding column (36) and the auxiliary transverse groove (37), it is ensured that when the fork plate (6) extends outside the bearing platform (4), the entire fork plate (6) will be in a stable state through the pulling of the stabilizing link (35). S5. When the auxiliary top plate (11) moves outward from the support platform (4), the auxiliary top plate (11) will drive the two auxiliary connecting rods (32) to move synchronously through the U-shaped frame plate (33). The auxiliary connecting rods (32) will move inward synchronously through the limiting of the auxiliary sliding rod (31) and the auxiliary sliding groove (30). Through the limiting and support of the auxiliary connecting rods (32), the stability of the auxiliary top plate (11) is ensured, and the stability of the fork plate (6) is improved when moving horizontally.
