All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] See attached document Figures 1-2As shown, this utility model provides a transfer vehicle stacking device, including a main body 1, a clamping assembly and a fork lifting mechanism 3. The main body 1 consists of a frame and a housing disposed on the outside of the frame. The clamping assembly consists of two sets of telescopic fork arms 2, which are used for clamping and lifting the transfer vehicle 5.

[0029] Telescopic fork arms 2 are symmetrically arranged on the left and right sides inside the main body 1. The fork arm lifting mechanism 3 is set on the main body 1 and is fixedly connected to the telescopic fork arms 2 on both sides through the connecting frame 4, which is used to drive the telescopic fork arms 2 on both sides to lift synchronously.

[0030] See attached document Figures 5-7 As shown, the telescopic fork arm 2 includes an L-shaped mounting frame 21, a fork arm 22, an electric telescopic rod 23, and a guide assembly 24. The fork arm 22 is telescopically and slidably arranged between the two horizontal cantilever arms of the L-shaped mounting frame 21. In this embodiment, the fork arm 22 is slidably connected to the L-shaped mounting frame 21 through a horizontal guide rail 7 and a guide rail slider 8. A horizontal guide rail 7 is fixed on both horizontal cantilever arms of the L-shaped mounting frame 21, and a guide rail slider 8 is fixed on both side walls of the fork arm 22. The fork arm 22 is slidably connected to the horizontal guide rail 7 on both side walls through the guide rail slider 8 on both side walls.

[0031] The upper end of the fork arm 22 is provided with a clamping part 221 for clamping and limiting the transfer vehicle 5. During the clamping process, the clamping part 221 plays a limiting role to prevent the transfer vehicle 5 from sliding in the front and back directions. The lower end of the fork arm 22 is provided with a support platform 222 for supporting the transfer vehicle 5. When the two fork arms 22 clamp the transfer vehicle 5, the support platform 222 is inserted into the bottom of the transfer vehicle 5. Then, the transfer vehicle 5 is lifted by lifting the fork arm 22.

[0032] One end of the electric telescopic rod 23 is fixed to the L-shaped mounting bracket 21, and the other end is fixed to the fork arm 22, used to push the fork arm 22 to extend and retract. When it is necessary to clamp the transfer cart 5, the electric telescopic rods 23 on both sides extend, driving the two fork arms 22 to move towards the center, thereby clamping and fixing the transfer cart 5. A guide assembly 24 is provided on the back of the L-shaped mounting bracket 21. The guide assembly 24 cooperates with the grooved slide rail 6 for guiding the telescopic fork arm 2 during lifting and lowering. The grooved slide rail 6 is vertically installed on the frame of the main body 1.

[0033] In this embodiment, the guide assembly 24 includes an L-shaped sheet metal part 241 and a fixed pulley 242. The L-shaped sheet metal part 241 is fixed to the back of the L-shaped mounting bracket 21. The fixed pulley 242 is installed on the side wall of the L-shaped sheet metal part 241. The fixed pulley 242 is inserted into the grooved slide rail 6. The fixed pulley 242 and the grooved slide rail 6 are in clearance fit for guiding the telescopic fork arm 2 during lifting and lowering. This arrangement can ensure that the telescopic fork arm 2 does not sway during lifting and lowering, thus improving the stability of its lifting and lowering process.

[0034] See attached document Figures 3-4As shown, the forklift lifting mechanism 3 includes a lifting panel 31, a driven shaft 32, a drive shaft 33, a lifting sprocket 34, a lifting chain 35, and a reduction motor 36. A longitudinal slide rail 9 is provided on the frame of the main body 1. The lifting panel 31 is slidably connected to the longitudinal slide rail 9 via a slider. The driven shaft 32 and the drive shaft 33 are respectively located on the upper and lower sides of the lifting panel 31. Both ends of the driven shaft 32 and the drive shaft 33 are fixedly mounted on the frame of the main body 1 via bearing seats. Lifting sprockets 34 are provided on both the left and right sides of the driven shaft 32 and the drive shaft 33. In this embodiment, the drive shaft 33 and the lifting sprocket 34 are fixedly connected by a key, and the driven shaft 32 and the lifting sprocket 34 are rotatably connected by bearings. The inner ring of the bearing is fixed to the driven shaft 32, and the outer ring of the bearing is fixed to the lifting sprocket 34.

[0035] A lifting chain 35 is wound between two lifting sprockets 34 on the same side. Both ends of the lifting chain 35 are fixedly connected to the lifting panel 31. The reduction motor 36 is fixedly installed on the frame of the main body 1, and the reduction motor 36 drives the drive shaft 33 to rotate through the sprockets and chain.

[0036] When the lifting panel 31 needs to be lifted, the reduction motor 36 drives the drive shaft 33 to rotate through the sprocket and chain. The rotation of the drive shaft 33 drives the sprocket 34 on the drive shaft 33 to rotate. The rotation of the sprocket 34 drives the lifting chain 35 around the outside of the sprocket 34 to move, thereby driving the lifting panel 31 to be lifted along the longitudinal slide rail 9. During the lifting process, the lifting panel 31 drives the telescopic fork arms 2 on both sides to be lifted synchronously through the connecting frame 4.

[0037] See attached document Figure 8 As shown, when stacking the transfer carts 5, the bottom transfer cart 5 is first clamped by the telescopic fork arm 2. During the clamping process, the clamping part 221 on the fork arm 22 plays a limiting role to prevent the transfer cart 5 from sliding in the front and back directions. At the same time, the support platform 222 on the fork arm 22 is inserted into the bottom of the transfer cart 5. Then, the fork arm lifting mechanism 3 lifts the telescopic fork arm 2 that clamps the transfer cart 5 through the connecting frame 4, thereby lifting the transfer cart 5.

[0038] The top four corners of the transfer vehicle 5 are provided with limiting grooves 51 for matching the bottom rollers of the transfer vehicle 5. When stacking the transfer vehicles 5, the rollers at the bottom of the upper transfer vehicle 5 are placed in the limiting grooves 51 at the top of the lower transfer vehicle 5 to prevent the transfer vehicles 5 from sliding and to play a limiting role.

[0039] After the transfer cart 5 is lifted, the transfer cart 5 to be stacked is moved to below the lifted transfer cart 5. Then, the fork lifting mechanism 3 drives the transfer cart 5 to descend and place the clamped transfer cart 5 on top of the bottom transfer cart 5. During the stacking process, the rollers at the bottom of the transfer cart 5 are placed in the groove 51 at the top of the lower transfer cart 5. Then, the telescopic fork arm 2 retracts and releases the clamped transfer cart 5, completing the stacking of the transfer cart 5. Finally, the fork lifting mechanism 3 drives the telescopic fork arm 2 to descend to the position where the bottom transfer cart 5 is clamped.

[0040] In this embodiment, a tri-color light 70 is provided on the top of the main body 1 to indicate the operating status of the device. When the device is running normally and automatically, the green light of the tri-color light 70 is on, and the yellow light is on when switching to manual mode. The main body 1 of the device is provided with a touch screen and an emergency stop button. Manual operation can be performed on the touch screen. When the emergency stop button is pressed or a malfunction occurs, the red light is on. When the light is on, the user can perform inspection and maintenance of the device according to the alarm information.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
