Description

Technical Field

[0001] This utility model relates to the field of warehouse stacking equipment technology, specifically a lane-type stacker crane. Background Technology

[0002] Stacker cranes are core handling equipment in modern automated storage and retrieval systems (AS / RS), primarily used for automated storage and retrieval of goods within narrow aisles of high-rise racking. These machines typically consist of a track-based system, a vertical lifting mechanism, and a platform mounted on the lifting mechanism. The platform is equipped with lateral sliding surfaces. Their working principle is based on three-dimensional motion: the crane body travels longitudinally along tracks laid on the aisle floor to locate the target cargo; the lifting mechanism drives the platform vertically to reach the target storage level; finally, the sliding surfaces on the platform extend laterally, delivering or retrieving goods from their designated storage locations.

[0003] In existing technologies, aisle stacker cranes typically rely on the lateral sliding motion of a slide to directly perform goods storage and retrieval operations. Subsequently, the longitudinal movement of the crane body within the aisle facilitates the transfer of goods between different storage locations. Regarding adaptability to material height, the lifting stroke of the slide and the structure of the platform are usually fixed for a given model of aisle stacker crane, which limits the effective range of goods height that can be stored and retrieved. When the height of the materials to be handled exceeds the design range of the equipment, it is often necessary to select another model of aisle stacker crane equipped with a different lifting mechanism or platform to adapt it.

[0004] However, since both the silo structure and the aisle stacker crane itself are large pieces of equipment, replacing different models of stacker cranes in actual operation involves complex disassembly, installation, and debugging processes, which are cumbersome and significantly affect the overall transfer efficiency of the warehousing system. Furthermore, existing aisle stacker cranes typically lack effective limiting and protection mechanisms on both sides of the slide during lateral movement. When the entire equipment moves rapidly, the platform is raised or lowered, or the slide itself extends or retracts, if the load is light or the center of gravity is unstable, there is a possibility that the goods may tip over or even fall off the slide. This not only poses potential safety risks but also further slows down the material transfer process due to damaged goods or the need for reoperation. Therefore, this utility model proposes an aisle stacker crane to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a lane-type stacker crane to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lane-type stacker crane, comprising: a lane-type stacker crane body and a platform installed on the lane-type stacker crane body, and a slide that can slide laterally on the platform, with height adjustment mechanisms provided on both sides of the platform, and a limit mechanism provided on the upper side of the height adjustment mechanism.

[0007] The height adjustment mechanism includes a rack that can move up and down along the side wall of the platform. One side of the rack meshes with one side of the large gear, and the other side of the large gear is provided with a first drive component that drives the large gear to rotate.

[0008] The limiting mechanism includes a support platform welded and fixed to the top of the rack. The upper surface of the support platform is slidably connected to the lower surface of the connecting block. One side of the upper surface of the connecting block is fixedly connected to one end of the crossbar, and the other end of the crossbar is fixedly connected to the anti-slip pressure plate. A second driving component for driving the connecting block to slide laterally along the support platform is connected to the other side of the upper surface of the connecting block.

[0009] Preferably, the large gear is rotatably connected to the side wall of the platform via a fixed shaft. The first drive assembly includes a small motor, which is fixedly installed on the inner side wall of the platform. The output end of the small motor passes through the side wall of the platform and is fixedly connected to the small gear. The small gear meshes with the large gear for transmission.

[0010] Preferably, a first sliding groove is provided on one side of the rack, and a second sliding groove is provided on the other side of the rack. The first sliding groove is slidably connected to the end of the U-shaped frame, and the second sliding groove is slidably connected to the limiting strip. The U-shaped frame and the limiting strip are both fixedly connected to the outer wall of the platform.

[0011] Preferably, a slide rail is fixedly connected to the upper surface of the support platform, the bottom of the connecting block is slidably connected to the slide rail, a limit groove is opened on one side of the support platform, the limit groove is slidably connected to the limit rod, and the limit rod is welded and fixed to the upper surface of the platform.

[0012] Preferably, the second drive assembly includes an electric cylinder, the output end of which is rotatably connected to one end of a hook plate via a long pin, the other end of which is rotatably connected to one end of a connecting frame via a short pin, the other end of which is rotatably connected to a connecting seat via a short pin, and the connecting seat is fixedly mounted on the upper surface of the connecting block.

[0013] Preferably, a support base is fixedly connected to one end of the lower surface of the support platform. The support base is rotatably connected to the lower side of the output end of the electric cylinder through a limiting pin. The hook plate is rotatably sleeved in the middle of the limiting shaft. Both ends of the limiting shaft are fixedly sleeved in the fixed seat. The fixed seat is fixedly connected to the upper surface of the support platform.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The working height of the limiting mechanism can be dynamically adjusted via height adjustment mechanisms (rack and pinion transmission with the first drive component) on both sides of the platform. This design allows a single stacker crane to adapt to material storage and retrieval needs of different heights without requiring replacement of the entire machine due to changes in material height. This significantly reduces the cumbersome process of equipment replacement, expands the scope of application, and effectively improves the transfer efficiency and practicality of the warehousing system.

[0016] 2. Utilizing a laterally extendable limiting mechanism (including anti-slip pressure plates, crossbars, and a second drive assembly), the system automatically conforms to the sidewalls of the goods after storage or retrieval, forming a stable constraint. This mechanism effectively prevents lightweight or unstable goods from tipping over or falling during rapid movement, lifting, or slide extension of the stacker crane, eliminating potential safety hazards and the risk of damage. Furthermore, by avoiding repetitive operations due to cargo accidents, it further ensures the continuity and overall efficiency of the material handling process. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a stacker crane with aisle configuration, comprising: a stacker crane body 1 and a platform 2 mounted on the stacker crane body 1, the platform 2 supporting a slide 3, and a slide 3 that can slide laterally on the platform 2 for loading and unloading goods via the slide 3. Height adjustment mechanisms are provided on both sides of the platform 2, and a limit mechanism is provided on the upper side of the height adjustment mechanism. The height of the limit mechanism is adjusted by the height adjustment mechanism to accommodate goods of different heights. The height adjustment mechanism and the limit mechanism are arranged in a square shape on the upper side of the platform 2. The height adjustment mechanism includes... A rack 4 that can move up and down along the side wall of the platform 2 has one side meshing with one side of a large gear 5 for transmission. The other side of the large gear 5 is provided with a first drive assembly for driving the large gear 5 to rotate. The limiting mechanism includes a support platform 6 welded and fixed to the top of the rack 4. The upper surface of the support platform 6 is slidably connected to the lower surface of the connecting block 7. The support platform 6 supports the connecting block 7. One side of the upper surface of the connecting block 7 is fixedly connected to one end of a crossbar 8. The other end of the crossbar 8 is fixedly connected to an anti-slip pressure plate 9. The crossbar 8 and the anti-slip pressure plate 9 are arranged vertically. The other side of the upper surface of the connecting block 7 is connected to a second drive assembly for driving the connecting block 7 to slide laterally along the support platform 6.

[0024] The slide 3 is moved to the cargo position by the track-walking mechanism, vertical lifting mechanism and the loading platform 2 located on the lifting mechanism of the aisle stacker crane body 1. The cargo is taken out by the lateral sliding of the slide 3. At this time, the large gear 5 is rotated by the first drive component. The large gear 5 meshes with the rack 4, so that the rack 4 slides vertically on the side wall of the loading platform 2. Then, the height of the support platform 6 is adjusted by the movement of the rack 4. After the adjustment is completed, the connecting block 7 of the second drive component slides laterally on the upper surface of the support platform 6. The connecting block 7 drives the crossbar 8 to move synchronously. The crossbar 8 moves towards the side wall of the cargo until the anti-slip pressure plate 9 abuts against the side wall of the cargo, thereby limiting the cargo and avoiding the risk of cargo tipping or falling during the rapid movement of the machine body. This reduces safety hazards and ensures transfer efficiency.

[0025] The large gear 5 is rotatably connected to the side wall of the platform 2 via a fixed shaft 10. The fixed shaft 10 limits the movement of the large gear 5. The first drive assembly includes a small motor 11, which is electrically connected to an external control device. The small motor 11 is fixedly installed on the inner side wall of the platform 2. The output end of the small motor 11 passes through the side wall of the platform 2 and is fixedly connected to the small gear 12. The small gear 12 meshes with the large gear 5, and the small gear 12 is driven to rotate by the small motor 11. A first sliding groove 13 is provided on one side of the rack 4, and a second sliding groove 14 is provided on the other side of the rack 4. The first sliding groove 13 is slidably connected to the end of the U-shaped frame 15, and the second sliding groove 14 is slidably connected to the limiting strip 16. The U-shaped frame 15 and the limiting strip 16 are both fixedly connected to the outer side wall of the platform 2.

[0026] When the height of the transported goods changes, the small motor 11 is started, which drives the small gear 12 fixedly connected to its output end to rotate. The small gear 12 then meshes with the large gear 5, which in turn meshes with the rack 4, driving the rack 4 to move. The rack 4 slides up and down along the side wall of the platform 2 through the sliding engagement of the first slide groove 13 and the U-shaped frame 15 with the second slide groove 14 and the limiting strip 16, thereby adjusting the height of the support platform 6. This makes it easier to accommodate goods of different heights, expands the scope of use, and improves the practicality of the entire device.

[0027] A slide rail 17 is fixedly connected to the upper surface of the support platform 6. The bottom of the connecting block 7 is slidably connected to the slide rail 17. The slide rail 17 limits the sliding of the connecting block 7. A limit groove 25 is opened on one side of the support platform 6. The limit groove 25 is slidably connected to the limit rod 26. The limit rod 26 is welded and fixed to the upper surface of the platform 2. Through the cooperation of the limit rod 26 and the limit groove 25, the support platform 6 can be further stabilized when moving up and down, thereby ensuring the stability of the limit on the goods. The second drive component includes an electric cylinder 18. The electric cylinder 18 is electrically connected to an external control device. The output end of the electric cylinder 18 is rotatably connected to one end of the hook plate 19 through a long pin shaft. The other end of the hook plate 19 is rotatably connected to one end of the connecting frame 20 via a short pin. The other end of the connecting frame 20 is rotatably connected to the connecting seat 21 via a short pin. The connecting seat 21 is fixedly installed on the upper surface of the connecting block 7. One end of the lower surface of the support platform 6 is fixedly connected to the support seat 22. The support seat 22 is rotatably connected to the lower side of the output end of the electric cylinder 18 via a limit pin. The support seat 22 provides limit support for the electric cylinder 18. The hook plate 19 is rotatably sleeved in the middle of the limit shaft 23. Both ends of the limit shaft 23 are fixedly sleeved in the fixed seat 24. The fixed seat 24 provides fixed support for the limit shaft 23. The fixed seat 24 is fixedly connected to the upper surface of the support platform 6.

[0028] Once the support platform 6 is adjusted to the appropriate height, the output end of the electric cylinder 18 is controlled. The output end of the electric cylinder 18, connected by a long pin, drives one end of the hook plate 19 to move. At this time, the electric cylinder 18 rotates at an angle in cooperation with the limit pin and the support seat 22. The hook plate 19 rotates under the limit of the limit shaft 23, thereby causing the other end of the hook plate 19 to drive one end of the connecting frame 20 to move through the connection of a short pin. The other end of the connecting frame 20, connected by the short pin, pushes the fixed seat 24 to move. The fixed seat 24 then drives the connecting block 7 to move along the slide rail 1. Under the limit of 7, the connecting block 7 moves towards the side wall of the goods, and the connecting block 7 then drives the crossbar 8 to move synchronously. The crossbar 8 moves towards the side wall of the goods until the anti-slip pressure plate 9 abuts against the side wall of the goods, thereby limiting the goods. When the output end of the control cylinder 18 retracts, the limitation on the goods can be released. By controlling the extension and retraction of the output end of the control cylinder 18, goods of different widths can be limited, improving convenience and practicality. However, if the goods fall and are damaged, the operation needs to be restarted, which further slows down the material transfer process.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
