Description
Technical Field

[0002] With the rapid development of the modern logistics industry, automated warehouses (AS / RS) and stacker cranes have been widely used to improve the efficiency of goods storage and retrieval. However, traditional stacker cranes are mainly designed for storing and retrieving entire stacks of materials and cannot meet the needs of handling single palletized goods within the racks of an AS / RS, resulting in low handling accuracy and operational efficiency. Furthermore, existing stacker cranes use forks directly mounted on telescopic modules for retrieving goods, with insufficient travel distance. This makes them unsuitable for long-distance, precise positioning and transport in AS / RS, and they cannot directly connect to automated guided vehicles (AGVs) or other transfer mechanisms located outside the racks, requiring the assistance of intermediate transfer and docking mechanisms.

[0040] To enable those skilled in the art to better understand the technical solution of this utility model, its specific embodiments are described in detail below with reference to the accompanying drawings:
[0041] Please see Figures 1 to 9 The preferred embodiment of this utility model is a long-stroke stacker crane, which includes a support base 35, a triangular prism frame, a long-stroke fork 34, a lifting mechanism and a rotary drive mechanism 36.
[0042] The rotary drive mechanism 36 is mounted on the support base 35; the rotary drive mechanism 36 consists of a rotary motor 362 and a rotary reducer 361 connected thereto.
[0043] The triangular prism-shaped frame includes a rotating top frame 41, a rotating mounting plate 40, and three guide support columns 30. The three guide support columns 30 are all vertically arranged in a triangular pattern. The rotating top frame 41 is fixed to the top of the three guide support columns 30 by a profile support mounting bracket 43 (see...). Figure 3 The rotating mounting plate 40 is fixed to the bottom end of the three guide support columns 30 via the connecting bracket 52 (see...). Figure 4 The rotating top frame 41 is provided with a rotating seat 42 at its top, and the rotating mounting plate 40 is connected to the rotating reducer 361 of the rotating drive mechanism 36. The rotating drive mechanism 36 drives the triangular prism frame to rotate. Specifically, the triangular prism frame is set in the three-dimensional rack, the rotating seat 42 is connected to the top of the three-dimensional rack, the support base 35 is set at the bottom of the three-dimensional rack, and the rotating motor 362 drives the rotating mounting plate 40 to rotate through the rotating reducer 361, thereby driving the entire triangular prism frame to rotate in the three-dimensional rack.
[0044] The long-stroke forks 34 are vertically movably mounted between the three guide support columns 30 via fork support brackets 342. For details, please refer to [link to relevant documentation]. Figure 5 Of the three guide support columns 30, two of them are equipped with lifting sliders 38 that can slide up and down along them. The two sides of the rear end of the fork support frame 342 are connected to the two lifting sliders 38 through connecting frames 341. The front end of the fork support frame 342 is equipped with a roller follower 343, which is connected to the remaining guide support column 30. The long-stroke fork 34 is mounted on the fork support frame 342. When the fork support frame 342 moves up and down along the three guide support columns 30, it drives the long-stroke fork 34 to move up and down, ensuring stable and smooth operation during the lifting process.
[0045] The lifting mechanism includes a lifting servo motor 48, a synchronous belt 32, a driving synchronous pulley 49, a driven synchronous pulley 44, and a counterweight assembly 50. The lifting servo motor 48 is mounted on a rotating mounting plate 40. The driving synchronous pulley 49 is connected to the output end of the lifting servo motor 48. The driven synchronous pulley 44 is mounted on the bottom end of the rotating top frame 41 via a driven bearing seat 45. Specifically, the driven bearing seat 45 is mounted on a bearing seat mounting bracket 46 with screws, and the bearing seat mounting bracket 46 is mounted on a bearing seat mounting bracket 46 with screws. The driven shaft 47 is installed in the driven bearing seat 45 at the bottom of the rotating top frame 41. The driven shaft 47 is installed in the driven bearing seat 45. The driven synchronous pulley 44 is sleeved on the driven shaft 47. The synchronous belt 32 is tensioned between the driving synchronous pulley 49 and the driven synchronous pulley 44. The synchronous belt 32 is connected to the counterweight assembly 44 and the fork support frame 342 through the synchronous belt clamp 39. The lifting servo motor 48 drives the synchronous belt 32 to rotate, which drives the fork support frame 342 and the long stroke forks 34 on it to move up and down along the three guide support columns 30.
[0046] Among the three guide support columns 30, a reinforcing support frame 33 is provided between the two guide support columns 30 with lifting sliders to improve the stability of the entire triangular prism frame. Rubber buffer limit blocks 51 are respectively provided on the lower part of the two guide support columns 30 with lifting sliders to limit and buffer the downward movement of the fork support frame 342.
[0047] Please see again Figure 6 and Figure 7 The long-stroke fork 34 includes a carbon fiber fork 53, a carbon fiber base plate 63, a sliding module one 54, a sliding module two 82, a module mounting base 60, and a stroke amplification pulley assembly.
[0048] An electromagnet 55 is provided at the end of the carbon fiber fork 53 for magnetically attracting the pallet, thereby moving the pallet and the goods on it. A sliding module 54 is located in the middle of the module mounting base 60, and the middle of the carbon fiber fork 53 is connected to the sliding module 54. The sliding module 54 drives the carbon fiber fork 53 to extend and retract. Specifically, fork rails 56 are provided on the front and rear sides of the module mounting base 60, and fork sliders are provided on the fork rails 56. The bottom end of the carbon fiber fork 53 is connected to the fork slider through a special mounting block, and the sliding module 54 drives the carbon fiber fork 53 to extend and retract along the fork rails 56.
[0049] The second sliding module 82 is located in the middle of the carbon fiber base plate 63. Telescopic slides 61 are respectively provided on the front and rear sides of the carbon fiber base plate 63. The module mounting base 60 is connected to the telescopic slides 61 through the slide wheel frame 64. Specifically, the telescopic slides 61 are set on the carbon fiber base plate 63 through the slide mounting bracket 62. The front and rear sides of the slide wheel frame 64 are respectively connected to the telescopic slides 61 on the front and rear sides of the carbon fiber base plate 63.
[0050] The stroke amplification pulley assembly is mounted on the carbon fiber base plate 63 and is connected to the slide rail frame 64 and the second sliding module 82 respectively. The second sliding module 82 drives the module mounting base 60 to extend and retract along the telescopic slide rail 61 through the stroke amplification pulley assembly, which in turn drives the carbon fiber fork 53 on the module mounting base 60 to extend and retract. The extension and retraction of the telescopic slide rail 61, together with the extension and retraction of the original first sliding module 54, can expand the extension and retraction stroke of the carbon fiber fork 53, realize long-distance extension and retraction, and allow the fork to extend directly outside the rack to directly dock with unmanned vehicles or other transfer mechanisms located outside the rack without the need for a transfer docking mechanism, thereby improving the accuracy of handling and the efficiency of operation.
[0051] Please see again Figure 8 and Figure 9 The stroke-enhancing pulley block includes pull column 1 (65), pull column 2 (66), pull column 3 (67), pull column 4 (68), wheel 1 (69), wheel 2 (70), wheel 3 (71), wheel 4 (72), wheel 5 (74), wheel 6 (75), wheel 7 (76), wheel 8 (77), wheel 9 (59), wheel 10 (84), steel cable 1 (78), steel cable 2 (79), spring 1 (80), spring 2 (81), wheel frame (83), and pull frame (85).
[0052] Pull post 1 65, wheel 9 59, wheel 10 84 and pull post 2 66 are arranged sequentially from front to back at one end of carbon fiber base plate 63, wheel frame 83 is arranged in the middle of the other end of carbon fiber base plate 63, wheel 76 and wheel 87 are arranged one in front of the other on wheel frame 83; pull post 3 67 and pull post 4 68 are arranged one in front of the other in the middle of carbon fiber base plate 63; wheel 5 74 and wheel 6 75 are arranged one above the other in the middle of slide wheel frame 64 via rotating column 73.
[0053] The pull frame 85 is mounted on the slider of the sliding module 2 82. Wheel 1 69 and Wheel 2 70 are mounted one above the other at the front of the pull frame 85 via the rotating column 73. Wheel 3 71 and Wheel 4 72 are mounted one above the other at the rear of the pull frame 85 via the rotating column 73.
[0054] One end of the steel cable 78 is connected to the pull post 65 by a screw, and the other end passes through the wheel 69, wheel 59, wheel 74, wheel 84 and wheel 71 in sequence and is connected to the pull post 66 by the spring 80.
[0055] One end of steel cable 279 is connected to pull post 367 by screws, and the other end passes through wheel 270, wheel 76, wheel 675, wheel 87 and wheel 472 in sequence before being connected to pull post 468 by spring 281.
[0056] When the slider on the sliding module 2 82 moves to one end, it drives the pull frame 85 and its wheels 69, 70, 71 and 72 to move synchronously. Through steel cables 78 and 79, it pulls wheels 74, 75 and the slide wheel frame 64 to move in the opposite direction, thereby causing the module mounting base 60 on the slide wheel frame 64 and the carbon fiber fork 53 on the module mounting base 60 to move synchronously. Specifically, when the slider on the second sliding module 82 moves forward, it pulls wheels 74 and 75 backward, thereby causing the slide wheel frame 64 to move backward and thus causing the module mounting base 60 and its carbon fiber fork 53 to retract; when the slider on the second sliding module 82 moves backward, it pulls wheels 74 and 75 forward, thereby causing the slide wheel frame 64 to move forward and thus causing the module mounting base 60 and its carbon fiber fork 53 to extend. By using the stroke amplification pulley system, the slider on the second sliding module 82 moves a distance that is twice the distance that wheels 74 and 76 move. In this way, the stroke amplification pulley group drives the module mounting base 60 and the carbon fiber fork 53 on it to extend and retract along the telescopic slide 61, instead of driving the carbon fiber fork 53 to extend and retract only through a single sliding module 54. This increases the stroke of the carbon fiber fork 53, thus adapting to the narrow space environment of the three-dimensional rack. Compared with the traditional short-stroke column stacker crane, the forks can be extended directly outside the rack to directly dock with unmanned vehicles or other transfer mechanisms located outside the rack without the need for a transfer docking mechanism.
[0057] In summary, the long-stroke stacker crane of this invention can meet the needs of handling single-pallet goods in the storage compartments of automated warehouses. It is adaptable to narrow space environments and can extend the forks directly outside the rack to directly connect with unmanned vehicles or other transfer mechanisms located outside the rack, without the need for intermediate transfer and docking mechanisms, thus improving handling accuracy and operational efficiency.
