Technical Field
[0001] This utility model relates to the technical field of stacker crane loading platforms, specifically a lightweight stacker crane loading platform device. Background Technology
[0002] Stacker cranes are the core equipment in modern automated warehouses (AS / RS). They primarily move along fixed aisle tracks in the X, Y, and Z directions to access and store unit pallets on fixed racks. The load-bearing capacity of the stacker crane is customized based on the weight of the goods to be stored and retrieved. Generally, stacker cranes with a load capacity of 200kg or less are considered light-duty stacker cranes. These cranes are used for storing and retrieving small logistics equipment, typically involving large volumes and high turnover requirements. Therefore, research on the safety, stability, and efficiency of light-duty stacker cranes is continuously deepening.
[0003] The Chinese patent announcement CN212198390U discloses a safe and stable lightweight stacker crane loading platform. Its key technical features include a main frame and forks. The main frame comprises a left side plate, a right side plate, and a base. An upper anti-collision plate is provided on the top of each of the left and right side plates, and a lower anti-collision plate is provided on the lower part of each of the left and right side plates. At least one first slider and one second slider are provided on each of the left and right side plates. A through-beam photoelectric switch is provided on each of the left and right side plates, and two diffuse reflection photoelectric switches are provided on the upper surface of the base. A U-shaped photoelectric switch and a set of limit switches are provided on either the left or right side plate. A guide strip is provided on each of the opposite sides of the left and right side plates.
[0004] In the above solution, the guide bar guides the material box, which has the following disadvantages: the loading platform can only limit the offset of the material box during use, but cannot actively correct the offset. Utility Model Content
[0005] The purpose of this invention is to provide a lightweight stacker crane loading platform device to solve the problem that the loading platform can only limit the offset of the material box and cannot actively correct the offset when in use.
[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a lightweight stacker crane loading platform device, comprising two mounting plates, both of which are fixed on a loading rack. Two support plates are detachably mounted inside the loading rack. A PLC controller is fixed to the right side of the loading rack. Forks are detachably mounted between the two mounting plates, and the forks are electrically connected to the PLC controller. Fixing holes are respectively opened on the front sides of the two support plates, and electric push rods are fixed in the two fixing holes respectively. The electric push rods are electrically connected to the PLC controller, and clamping plates are fixed to one end of the telescopic rods of the two electric push rods respectively.
[0007] Preferably, two limiting holes are respectively opened on the front side of the two support plates, and two limiting posts are respectively fixed on the outer side of the two clamping plates, and the two limiting posts are slidably inserted into the two limiting holes.
[0008] Preferably, a first anti-slip pad is fixed to the inner side of each of the two clamping plates, and a second anti-slip pad is fixed to the top surface of the forks.
[0009] Preferably, the outer wall of the rack has two mounting holes on the left and right sides respectively, and the two support plates have mounting grooves on the left and right sides respectively. Springs are fixed inside the two mounting grooves, and mounting blocks are fixed to the outer ends of the two springs respectively. The two mounting blocks are slidably inserted into the two mounting holes.
[0010] Preferably, the top and bottom surfaces of the two mounting slots are respectively provided with sliding grooves, and the top and bottom surfaces of the two mounting blocks are respectively fixed with sliders, and the two sliders are respectively slidably disposed in the two sliding grooves.
[0011] Preferably, the top surfaces of the two mounting plates are respectively provided with two threaded grooves, and the fork is provided with a plurality of threaded holes, and bolts are threadedly connected to the plurality of threaded holes, and the threaded ends of the bolts are threadedly connected to the inside of the threaded grooves.
[0012] Compared with existing technologies, a lightweight stacker crane loading platform device that adopts the above-mentioned technical solution has the following beneficial effects:
[0013] 1. In use, through the combined use of mounting plate, rack, support plate, PLC controller, forks, fixing holes, electric push rod and clamping plate, it not only achieves effective clamping of material boxes of different sizes to prevent them from falling, but also has the function of correcting the fork loading of the material box, ensuring that the material box is parallel to the direction of movement of the forks, thus improving the versatility and operational accuracy of the stacker crane loading platform device.
[0014] Second, during use, the clamping plate can be limited to ensure that it does not shift or wobble during forward and backward movement, thus improving the stability of the clamping plate movement. The first anti-slip pad is in close contact with the surface of the material box, increasing the friction between the two and effectively preventing the material box from sliding during clamping, thus ensuring that the material box is firmly clamped. When the material box is placed on the forks, the second anti-slip pad is also in contact with the bottom of the material box, increasing friction to prevent the material box from sliding or shifting during the movement of the forks, allowing the material box to be placed stably on the forks, providing a good foundation for subsequent clamping and transportation operations. The disassembly and assembly method is simple and convenient, requiring no complicated tools or cumbersome steps, saving the time and energy of the staff, and facilitating the daily maintenance or replacement of the support plate and electric push rod, thus improving the maintainability of the entire loading platform device.
[0015] Thirdly, during use, when the operator moves the mounting block, the slider slides inside the groove, which limits the mounting block and ensures that it will not shift or wobble when moving left or right. The assembly and disassembly method is simple and easy, facilitating regular maintenance of the forks or replacement with different fork specifications as needed, thus improving the flexibility and maintainability of the loading platform device.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0022] like Figures 1-4As shown, a lightweight stacker crane loading platform device includes two mounting plates 1, both of which are fixed on a loading rack 2. Two support plates 3 are detachably installed inside the loading rack 2. A PLC controller 4 is fixed on the right side of the loading rack 2. The PLC controller 4 is a Siemens S7-200. A fork 5 is detachably installed between the two mounting plates 1. The fork 5 is electrically connected to the PLC controller 4. Fixing holes 6 are respectively opened on the front side of the two support plates 3. Electric push rods 7 are fixed in the two fixing holes 6 respectively. The electric push rods 7 are electrically connected to the PLC controller 4. Clamping plates 8 are respectively fixed to one end of the telescopic rods of the two electric push rods 7.
[0023] In operation, the staff first installs the rack 2 onto the stacker crane's lifting mechanism. When a food box is successfully placed on the forks 5, the PLC controller 4 activates two electric push rods 7. At this time, the telescopic rods of the two electric push rods 7 extend synchronously and smoothly, causing two clamping plates 8, each fixed to one end of the telescopic rod, to move simultaneously and move closer to each other. During this process, the clamping plates 8 clamp the food box from the front and rear sides, improving the stability of the food box during the movement of the rack 2 and effectively preventing the food box from falling due to shaking or bumping, thus ensuring the safety of goods transportation. Since the moving distance of clamping plate 8 can be adjusted according to the extension and retraction of electric push rod 7, it can adapt to boxes of different sizes. In addition, during the clamping process, the force applied by clamping plate 8 to the box can also correct the box's deviation, keeping the box parallel to the movement direction of fork 5, ensuring the box's positional accuracy during transportation. When fork 5 places the box on the unit pallet of the fixed rack, electric push rod 7 is activated again, moving the two clamping plates 8 away from the box and releasing the clamping. Then, fork 5 moves the box onto the unit pallet, completing a complete cargo handling process. Through the coordinated use of mounting plate 1, rack 2, support plate 3, PLC controller 4, fork 5, fixing hole 6, electric push rod 7, and clamping plate 8, not only is effective clamping of boxes of different sizes achieved, preventing them from falling, but it also has the function of correcting the deviation of the box on fork 5, ensuring that the box is parallel to the movement direction of fork 5, thus improving the versatility and operational accuracy of the stacker crane loading platform device.
[0024] like Figures 1-4 As shown, two limiting holes 9 are respectively opened on the front side of the two support plates 3, and two limiting posts 10 are respectively fixed on the outer side of the two clamping plates 8. The two limiting posts 10 are slidably inserted into the two limiting holes 9.
[0025] In use, when the clamping plate 8 moves back and forth via the electric push rod 7, the limiting post 10 slides into the limiting hole 9, which can limit the clamping plate 8 and ensure that the clamping plate 8 will not deviate or shake during the back and forth movement, thus improving the stability of the movement of the clamping plate 8.
[0026] like Figures 1-4 As shown, the inner sides of the two clamping plates 8 are respectively fixed with a first anti-slip pad 11, and the top surface of the fork 5 is fixed with a second anti-slip pad 12. The outer wall of the rack 2 has two mounting holes 13 on the left and right sides respectively. The two support plates 3 have mounting grooves 14 on the left and right sides respectively. The two mounting grooves 14 are respectively fixed with springs 15 inside. The outer ends of the two springs 15 are respectively fixed with mounting blocks 16. The two mounting blocks 16 are slidably inserted into the two mounting holes 13 respectively.
[0027] During use, when the clamping plate 8 holds the material box, the first anti-slip pad 11 is in close contact with the surface of the material box, increasing the friction between the material box and the material box. This effectively prevents the material box from sliding during the clamping process, ensuring that the material box is firmly clamped. When the material box is placed on the fork 5, the second anti-slip pad 12 is also in contact with the bottom of the material box. By increasing the friction, it prevents the material box from sliding or shifting during the movement of the fork 5, allowing the material box to be placed stably on the fork 5, providing a good foundation for subsequent clamping and transportation operations. When the worker needs to install the support plate 3 and the electric push rod 7 on the rack 2, first press the two mounting blocks 16 into the two mounting slots 14 respectively. At this time, the spring 15 is in a compressed state. Then, place the support plate 3 in the rack 2 so that the mounting slots 14 are aligned with the mounting holes 13. At this time, the spring 15 can automatically reset the mounting blocks 16, so that they slide into the mounting holes 13, completing the installation of the support plate 3 and the electric push rod 7. Conversely, when the worker needs to disassemble the support plate 3 and the electric push rod 7, simply press the two mounting blocks 16 into the two mounting slots 14 respectively, so that the two mounting blocks 16 are respectively disengaged from the two mounting holes 13. The disassembly and assembly methods are simple and convenient, without complicated tools and cumbersome steps, saving the worker's time and energy. It is convenient for the worker to perform daily maintenance or replacement of the support plate 3 and the electric push rod 7, improving the maintainability of the entire loading platform device.
[0028] like Figures 1-4 As shown, the top and bottom surfaces of the two mounting slots 14 are respectively provided with sliding grooves 17, the top and bottom surfaces of the two mounting blocks 16 are respectively fixed with sliders 18, the two sliders 18 are respectively slidably arranged in the two sliding grooves 17, the top surfaces of the two mounting plates 1 are respectively provided with two threaded grooves 19, the fork 5 is provided with several threaded holes 20, and bolts 21 are threadedly connected in the several threaded holes 20 respectively, and the threaded end of the bolt 21 is threadedly connected to the inside of the threaded groove 19.
[0029] During use, when the operator moves the mounting block 16, the slider 18 slides inside the groove 17, which limits the mounting block 16 and ensures that it will not shift or wobble when moving left or right. When maintenance or replacement of the fork 5 is required, the operator only needs to unscrew the bolt 21 threaded into the threaded hole 20 and threaded groove 19 to remove the fork 5 from the mounting plate 1. Conversely, when a new fork 5 needs to be installed, the fork 5 is placed in a suitable position so that the threaded hole 20 is aligned with the threaded groove 19, and then the bolt 21 is screwed into the threaded hole 20 and threaded groove 19 in sequence to complete the installation of the fork 5. The disassembly and assembly methods are simple and easy to implement, which facilitates the operator to perform regular maintenance on the fork 5 or replace forks 5 of different specifications according to actual needs, improving the flexibility and maintainability of the loading platform device.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
