Description

Technical Field

[0001] This utility model relates to the field of warehousing and logistics equipment technology, and in particular to a stacker crane. Background Technology

[0002] Smart warehouses are a crucial component of modern logistics systems, enabling efficient storage, retrieval, and management of goods through automated equipment and information management systems. Shelving, as the core facility in a smart warehouse used for supporting and classifying goods, directly impacts overall storage capacity through its operational efficiency. Stacker cranes, as key handling equipment in smart warehousing systems, typically operate at high speeds within rack aisles, automating the storage and retrieval of goods. They possess advantages such as high precision, high efficiency, and a high degree of automation, playing an irreplaceable role in modern warehousing and logistics systems.

[0003] Existing technologies, such as the stacker crane disclosed in Chinese utility model patent CN218909759U, include a main body, a drive motor, a double-threaded rod, and guide components. The guide rail has a structure on both sides where a main guide wheel and a driven guide wheel cooperate. By adjusting the clamping force of the main guide wheel and the driven guide wheel on the guide rail, excessive clamping can be prevented from causing excessive movement resistance, thereby saving power and improving stacking efficiency. At the same time, this structure also enhances the stability of the stacker crane running on the track, prevents tilting, and improves operational safety. However, in practical applications, there are still significant shortcomings: the stacker crane's cargo pallet lacks limiting and guiding structures on both sides. During cargo pushing and unloading operations, vibration or displacement can easily cause cargo to slip, posing a safety hazard.

[0004] Therefore, given the shortcomings of existing technologies, we urgently need a new type of stacker crane to solve the aforementioned problems. This new type of stacker crane should, while maintaining the original operational stability and energy efficiency, add a limiting and guiding structure for cargo pallets to improve the safety and reliability of the unloading process. It should also possess stronger cargo adaptability and environmental adaptability, better meeting the needs of modern intelligent warehousing systems for high-safety, high-efficiency, and multi-functional equipment, and providing strong support for the intelligent and standardized development of the logistics industry.

Several rotating grooves 11 are opened on one side of the limiting plate 15. Contact wheels 16 are rotatably connected inside the rotating grooves 11.

[0025] The workflow is as follows: When performing goods storage and retrieval tasks in the intelligent warehousing system, the equipment achieves overall horizontal movement through the slide rail 1. The mounting base 2 slides and engages on the top of the slide rail 1, driving the lifting frame 4 to move along the slide rail direction. Both sides of the lifting frame 4 are equipped with sliding components that engage vertically and horizontally, ensuring stable vertical movement and flexible lateral movement. Vertical lifting components are installed on both sides of the top of the lifting frame 4 to drive the support plate 3 for lifting and adjustment, enabling precise alignment with rack layers of different heights. When the stacker crane reaches the target position… After placement, the pushing component connected to the bottom of the support plate 3 is activated. Its output end is connected to one end of the support plate 3, pushing the pushing structure forward and pushing the goods to the designated position. During this process, limit plates 15 are provided on both sides of the top of the support plate 3. The limit plates 15 are fixed to the bottom of the support plate 3 in a detachable manner, and several rotating grooves 11 are opened on one side. Each rotating groove 11 is rotatably connected to a contact wheel 16. During the process of pushing the goods, the contact wheel 16 rolls and contacts the side of the goods, playing a limiting and guiding role, preventing the goods from slipping or tilting due to vibration or displacement.

[0026] Example 2

[0027] Please see Figure 1-5As shown in the figure, in this embodiment of a stacker crane, the lifting frame 4 has moving slots 9 on both sides. The sliding component includes a sliding block 6 and a moving plate 7. One end of the moving plate 7 is fixedly connected to the side wall of the sliding block 6, and the other end is slidably engaged with the moving slot 9. One side of the sliding block 6 is slidably engaged with the side wall of the support plate 3. Specifically, by designing the moving slots 9 on both sides of the lifting frame 4 and the sliding component including the sliding block 6 and the moving plate 7, during operation, one end of the moving plate 7 is fixedly connected to the side wall of the sliding block 6, and the other end is slidably engaged with the moving slot 9. One side of the sliding block 6 is slidably engaged with the side wall of the support plate 3, which realizes the flexible movement of the support plate 3 in the horizontal and vertical directions, ensuring the accurate positioning and stable operation of the equipment when storing and retrieving goods, and achieving the effect of improving the flexibility and accuracy of the stacker crane operation.

[0028] The vertical lifting assembly includes a lifting cylinder 10 that is bolted to the top of the lifting frame 4. The output end of the lifting cylinder 10 is connected to the top of the moving plate 7. Specifically, through the design of the lifting cylinder 10 being bolted to the top of the lifting frame 4 and the output end of the lifting cylinder 10 being connected to the top of the moving plate 7, when it is necessary to adjust the height of the support plate 3 to adapt to different shelf layers, the lifting cylinder 10 is activated, driving the moving plate 7 to move up and down, thereby achieving precise adjustment of the height of the support plate 3. This enables the stacker crane to efficiently and accurately complete the storage and retrieval tasks of goods, achieving the effect of enhancing equipment adaptability and ease of operation.

[0029] The pushing assembly includes a bottom frame 8 and a pushing cylinder 5 connected to one side of the bottom frame 8. Both ends of the bottom frame 8 are connected to adjacent sliding blocks 6, and the output end of the pushing cylinder 5 is connected to one end of the support plate 3. Specifically, by connecting the bottom frame 8 to both ends of the adjacent sliding blocks 6 and connecting the pushing cylinder 5 to one side of the pushing assembly, and connecting the output end of the pushing cylinder 5 to one end of the support plate 3, when performing the cargo pushing action, the pushing cylinder 5 is activated, driving the support plate 3 to move horizontally along the slide rail 1, thereby realizing the automatic pushing of the cargo. This design not only improves work efficiency but also ensures the consistency and accuracy of operation, achieving the goal of enhancing automation and improving work efficiency.

[0030] Example 3

[0031] Please see Figure 1-5As shown, in this embodiment of a stacker crane, the pushing structure includes a second pushing cylinder 13 and a pushing plate 12 connected to the top of the support plate 3 via an upright plate 14. The output end of the second pushing cylinder 13 is connected to one side of the pushing plate 12, and a number of abutment posts made of rubber are connected to one side of the pushing plate 12. Specifically, through the arrangement of the upright plate 14, the second pushing cylinder 13, and the pushing plate 12 in the pushing structure, when unloading is required, the second pushing cylinder 13 is activated, and its output end pushes the pushing plate 12 forward. A number of abutment posts made of rubber are connected to one side of the pushing plate 12, which contact and smoothly push the goods to the designated position. The whole process avoids damage to the goods, while improving unloading efficiency and accuracy, and achieving the effect of optimizing the unloading process and improving operational safety.

[0032] Several positioning plates 18 are fixedly connected to one side of the bottom of the limiting plate 15. The top of the positioning plate 18 has a through hole, and a positioning screw 17 is fixedly connected to the top of the support plate 3 at one end inside the through hole. The positioning screw 17 is threadedly connected to a positioning nut 19 at one end. Specifically, by using several positioning plates 18 fixed to one side of the bottom of the limiting plate 15, each positioning plate 18 has a through hole at the top and is fixedly connected to the top of the support plate 3 by the positioning screw 17 and then locked with the positioning nut 19, the position of the limiting plate 15 can be quickly adjusted according to the specific size of the goods, ensuring that the goods receive good lateral support during transportation and preventing the goods from slipping due to vibration or displacement. This achieves the effect of improving the stability of the goods loading and reducing safety hazards.

[0033] The overall structure of this stacker crane includes key components such as slide rail 1, mounting base plate 2, lifting frame 4, support plate 3, sliding parts, vertical lifting assembly, pushing assembly, pushing structure, limit plate 15, rotating groove 11, contact wheel 16, moving groove 9, sliding block 6, moving plate 7, lifting cylinder 10, bottom frame 8, pushing cylinder one 5, upright plate 14, pushing cylinder two 13, pushing plate 12, contact column, positioning plate 18, positioning screw 17 and positioning nut 19. In actual operation, the equipment achieves overall horizontal movement via the slide rail 1. The mounting base plate 2 slides on the top of the slide rail 1, driving the lifting frame 4 to move smoothly along the slide rail direction. The lifting frame 4 has moving slots 9 on both sides. The sliding component consists of a sliding block 6 and a moving plate 7. One end of the moving plate 7 is fixedly connected to the side wall of the sliding block 6, and the other end is inserted into the moving slot 9 and can slide up and down. One side of the sliding block 6 slides against the side wall of the support plate 3, thus ensuring stable movement of the support plate 3 in both vertical and horizontal directions. The vertical lifting assembly consists of a lifting cylinder 10, whose top is bolted to the lifting frame 4. The output end is connected to the top of the moving plate 7. When the height of the support plate 3 needs to be adjusted, the lifting cylinder 10 is activated, driving the moving plate 7 to move up and down, thereby driving the support plate 3 to precisely align with the height of different shelf layers. The pushing assembly includes a bottom frame 8 and a pushing cylinder 5. Both ends of the bottom frame 8 are connected to the sliding block 6, and the pushing cylinder 5 is set... On one side of the bottom frame 8, its output end is connected to one end of the support plate 3, which is used to control the support plate 3 to move horizontally along the slide rail to complete the cargo pushing action; the pushing structure consists of a vertical plate 14, a second pushing cylinder 13 and a pushing plate 12. The second pushing cylinder 13 is fixed to the top of the support plate 3 through the vertical plate 14, and its output end is connected to the pushing plate 12. The pushing plate 12 has multiple rubber contact posts on one side, which flexibly push the cargo during unloading to avoid damage; the support plate 3 has limit plates 15 on both sides of the top. The limit plates 15 are detachably connected through the bottom positioning plate 18, positioning screw 17 and positioning nut 19, which makes it easy to flexibly adjust the position according to the cargo size. The limit plates 15 have several rotating grooves 11 on one side, and each rotating groove 11 is rotatably connected to a contact wheel 16. During the process of the cargo being pushed out, the contact wheel 16 rolls in contact with the side of the cargo to provide a limiting and guiding function to prevent the cargo from slipping or tilting due to vibration or displacement.

[0034] The design of this stacker crane fully considers the core problems existing in the current technology, namely that the cargo pallets of traditional stacker cranes are not equipped with limiting and guiding structures, which can easily cause the cargo to slip during the unloading process due to vibration or displacement, posing a safety hazard. By introducing the combined structure of the limiting plate 15, rotating groove 11, and contact wheel 16, the stability and safety of cargo transportation and unloading are effectively improved, preventing cargo from tipping over or slipping due to uneven force or external impact. Meanwhile, the limiting plate 15 adopts a detachable design and can be quickly adjusted via the positioning plate 18, positioning screw 17, and positioning nut 19, enhancing the equipment's adaptability to different types of cargo and improving operational flexibility. In the pushing structure, the second pushing cylinder 13 works in conjunction with the pushing plate 12, combined with the flexible contact method of the rubber contact column, which not only improves unloading efficiency but also reduces the risk of damage to the cargo surface. The first pushing cylinder 5 in the pushing assembly works in tandem with the bottom frame 8 to achieve the automatic pushing function of the support plate 3, further improving the degree of automation and operational consistency. The multi-directional sliding cooperation design of the sliding parts and the vertical lifting assembly gives the whole machine higher operating accuracy and stability, adapting to the high-efficiency operation requirements of complex warehousing environments.
