Description

Technical Field

[0001] This application relates to the field of pallet truck fork technology, and more specifically, to an electric side-shifting fork for a pallet stacker truck. Background Technology

[0002] The electric side-shift forks of a pallet stacker are an automated logistics operation device integrated into the pallet stacker. They primarily use an electric drive system to achieve lateral movement of the forks, precisely adjusting the lateral position of the forks and goods without changing the vehicle's direction of travel. This meets the needs of picking up, placing, stacking, and handling goods in confined spaces. The device typically consists of the fork body, electric drive mechanism, control system, and guiding components. It features convenient operation, high positioning accuracy, and fast response speed, effectively improving the operational flexibility of pallet stackers in warehousing and logistics scenarios.

[0003] In traditional forklift operation scenarios, when a forklift travels to a confined space, the length of the forks directly hinders the vehicle's turning operation. The forklift often needs to first retreat to a wider area to adjust the turning angle before returning to its original position to transport goods. This results in a cumbersome and time-consuming operation process, significantly reducing the forklift's work efficiency. It also forces the forklift to reduce its range of activity in complex warehousing environments due to space limitations, especially in densely packed racking areas or workshops with narrow aisles. Utility Model Content

[0004] To address the aforementioned issues, this application provides an electric side-shifting fork for a pallet stacker truck.

[0005] The electric side-shift forklift provided in this application adopts the following technical solution:

[0006] An electric side-shifting fork for a pallet stacker includes a connecting plate disposed on one side of the stacker body, two connecting forks fixedly connected to the front side of the connecting plate, and a rotating component provided on the front side of each connecting fork.

[0007] The rotating assembly includes two movable forks. One end of each movable fork is rotatably connected to a corresponding connecting fork via a pivot. Limiting plates are fixedly connected to the bottom of each connecting fork. The two limiting plates are located at the bottom of the corresponding movable fork. Locking components are provided on opposite sides of the two pivots.

[0008] By using the above technical solution, a rotating component is installed on the front side of the connecting fork, which achieves the effect of flexible adjustment of the fork angle, allowing the fork to rotate from a parallel state to a vertical state, greatly reducing the lateral space occupied, solving the problem of traditional forklifts being hindered by the length of the forks, improving the passability in narrow spaces, and allowing the forklift to adjust the fork position without moving the entire vehicle, reducing the ineffective operation of turning back and forth in wide areas in traditional operations, and improving work efficiency.

[0009] Furthermore, each locking assembly includes a connecting seat, which is fixedly connected to the rotating shaft. An insert is rotatably connected inside the connecting seat, and a groove is provided on one side of the limiting plate, with the insert matching the groove.

[0010] With the above technical solution, the mechanical pre-locking of the insert block eliminates the need for manual support once the fork angle is fixed. Operators can simultaneously operate the insert lever with both hands, significantly simplifying the operation process and improving operational efficiency. Especially in high-frequency angle adjustment scenarios, it can effectively reduce unnecessary time consumption and significantly improve the throughput efficiency of warehousing and logistics.

[0011] Furthermore, two limiting rods are fixedly connected to the top of the connecting plate, and two slots are opened at the top of each limiting rod.

[0012] Furthermore, each of the two moving forks has a limit slot at the end furthest from the connecting fork, and a rod is placed between the two corresponding slots and the limit block.

[0013] Furthermore, limit blocks are fixedly connected to both ends of the two insert rods, and the two limit blocks are used to restrict the rotation of the moving forks.

[0014] Furthermore, a side-shifting connecting frame is provided between the stacker crane body and the connecting plate, and the connecting plate and the side-shifting connecting frame are slidably connected.

[0015] Furthermore, a placement box is provided on one side of the stacker crane body, which is used to place two insert rods.

[0016] With the above technical solution, when the fork angle is adjusted and the insert rod is no longer in use, the operator puts the insert rod into the placement box on one side of the stacker crane body.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] This utility model achieves the effect of flexible adjustment of the fork angle by setting a rotating component on the front side of the connecting fork, so that the fork can rotate from a parallel state to a vertical state, greatly reducing the lateral space occupied, solving the problem of traditional forklifts being hindered by the length of the forks, improving the passability in narrow spaces, and allowing the forklift to adjust the fork position without moving the entire vehicle, reducing the ineffective operation of turning back and forth in wide areas in traditional operations, and improving work efficiency.

[0019] This invention utilizes the mechanical pre-locking of the insert block, eliminating the need for manual support once the fork angle is fixed. Operators can simultaneously operate the insert lever with both hands, significantly simplifying the operation process and greatly improving work efficiency. Especially in high-frequency angle adjustment scenarios, it effectively reduces wasted time and significantly improves the throughput efficiency of warehousing and logistics.

Detailed Implementation

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] Reference Figures 1-5 An electric side-shifting fork for a pallet stacker includes a connecting plate 2 disposed on one side of the stacker body 1, and two connecting forks 3 are fixedly connected to the front side of the connecting plate 2, and a rotating component is provided on the front side of each of the two connecting forks 3.

[0028] The rotating assembly includes two movable forks 4. One end of each movable fork 4 is rotatably connected to a corresponding connecting fork 3 via a rotating shaft 6. Limiting plates 5 are fixedly connected to the bottom of each of the two connecting forks 3. The two limiting plates 5 are located at the bottom of the corresponding movable fork 4. Locking components are provided on opposite sides of the two rotating shafts 6.

[0029] When the forklift travels to a confined space and the fork angle needs to be adjusted, there are no items placed on the moving fork 4 or the connecting fork 3. Therefore, the moving fork 4 can be manually rotated 90 degrees to make it vertical. Then, the moving fork 4 is locked by the locking assembly. After locking, the insert rod 9 is placed into the corresponding limit groove 11 and slot 7. At this time, the two limit blocks 10 and the insert rod 9 form a limit structure, so that the moving fork 4 is fixed and limited.

[0030] This device achieves flexible adjustment of the fork angle by setting a rotating component on the front side of the connecting fork 3, allowing the forks to rotate from a parallel state to a vertical state, greatly reducing the lateral space occupied, solving the problem of traditional forklifts being hindered by the length of the forks, improving the passability in narrow spaces, and allowing the forklift to adjust the fork position without moving the entire vehicle, reducing the ineffective operation of turning back and forth in wide areas in traditional operations, and improving work efficiency.

[0031] Reference Figures 3-4 Each locking assembly includes a connecting seat 12, which is fixedly connected to the rotating shaft 6. An insert 13 is rotatably connected inside the connecting seat 12. A groove 14 is provided on one side of the limiting plate 5, and the insert 13 matches the groove 14.

[0032] When it is necessary to fix the rotation angle of the moving fork 4, after rotating to the vertical state, the insert block 13 rotates with the rotating shaft 6. Then, the insert block 13 is pushed down so that it is inserted into the groove 14 of the limiting plate 5, which initially locks the rotating moving fork 4. No hand support is required when placing the insert rod 9.

[0033] With the mechanical pre-locking of the insert block 13, the moving fork 4 is fixed at an angle without the need for manual support. Operators can simultaneously operate the insert lever 9 with both hands, greatly simplifying the operation process and significantly improving work efficiency. Especially in high-frequency angle adjustment scenarios, it can effectively reduce unnecessary time consumption and significantly improve the throughput efficiency of warehousing and logistics.

[0034] Reference Figures 1-4 Two limiting rods 8 are fixedly connected to the top of the connecting plate 2. Two slots 7 are opened at the top of each of the two limiting rods 8. Limiting grooves 11 are opened at the ends of the two moving forks 4 away from the connecting forks 3. Insert rods 9 are placed between the two corresponding slots 7 and the limiting blocks 10. The two ends of the two insert rods 9 are fixedly connected to the limiting blocks 10. The two limiting blocks 10 are used to limit the rotation of the moving forks 4.

[0035] Based on the pre-locking of the insert block 13, the limiting blocks 10 at both ends of the insert rod 9 are aligned and inserted into the slots 7 of the limiting rod 8 and the limiting grooves 11 of the moving fork 4, respectively. At this time, the insert rod 9 forms a physical constraint in the axial direction through the limiting blocks 10, preventing the moving fork 4 from rotating around the pivot 6, thus achieving secondary locking. The radial locking of the insert block 13 and the axial limiting of the insert rod 9 complement each other, jointly ensuring that the fork maintains a stable posture during the locking process.

[0036] Reference Figures 1-4 A side-shifting connecting frame 16 is provided between the stacker body 1 and the connecting plate 2. The connecting plate 2 and the side-shifting connecting frame 16 are slidably connected. A placement box 15 is provided on one side of the stacker body 1. The placement box 15 is used to place two insert rods 9.

[0037] The connecting plate 2 is slidably connected to the side-shifting connecting frame 16 (e.g., the electric guide rail drives the side-shifting connecting frame 16 on one side to move), thereby pushing the entire fork to move laterally in the horizontal direction, realizing the adjustment of the fork position. When the fork angle adjustment is completed and the insert rod 9 is no longer used, the operator puts the insert rod 9 into the placement box 15 on one side of the stacker crane body 1.

[0038] Working Principle: When the forklift needs to adjust the fork angle in a confined space, the operator first manually rotates the moving fork 4 under no-load conditions, rotating it 90 degrees around the pivot 6 from its initial state parallel to the connecting fork 3 to a vertical state. After rotation, the locking assembly is operated, pushing the insert 13 in the connecting seat 12 downwards so that it inserts into the groove 14 of the limiting plate 5. The engagement of the insert 13 with the groove 14 initially locks the moving fork 4, at which point the rotational freedom of the pivot 6 is radially restricted. Next, the operator takes the insert rod 9, aligns the limiting blocks 10 at both ends with the slot 7 at the top of the limiting rod 8 and the limiting groove 11 at the far end of the moving fork 4, respectively. The insert rod 9 forms a physical constraint in the axial direction through the limiting blocks 10, preventing the moving fork 4 from moving axially around the pivot 6, completing a secondary locking. Thus, through the dual mechanism of radial locking and axial limiting, the fork angle is fixed, allowing entry into the confined space. After entry, the locking state is released.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
