[0002] A forklift flipping device is a device used to flip the forklift cargo in specific situations. Normally, forklifts are mainly used to carry and stack cargo, but in some cases, the cargo may need to be flipped for specific operations or processing. The flipping device allows the forklift to flip the cargo from one direction to another when needed to meet specific handling or processing needs.

[0003] A Chinese patent with authorization announcement number CN218879386U discloses a forklift clamping structure that is convenient for unloading. By setting a rotating motor, when the forklift is used to transport goods and the placement angle of the goods needs to be adjusted, the rotating motor is started, so that the rotating motor drives the rotating column to rotate through the No. 1 gear and the No. 2 gear, that is, the No. 2 clamping frame is driven to rotate through the No. 2 hydraulic column, so that the goods between the No. 1 clamping frame and the No. 2 clamping frame can be flipped.

[0004] However, the forklift flipping device mentioned above cannot effectively control the clamping force when clamping the goods, resulting in excessive clamping force when the handle is used to control the flipping device to clamp the goods, causing cracks and damage to the surface of the goods.

DETAILED DESCRIPTION

[0028] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0029] Embodiment 1

[0030] like Figure 1-Figure 4As shown in the figure, a forklift turning device proposed by the present utility model includes a vehicle frame 1, a turning assembly, and a driving mechanism. A moving plate 2 for carrying the turning device and a lifting assembly for driving the lifting of the moving plate 2 are provided on the vehicle frame 1. Limit members for defining the moving trajectory of the moving plate 2 are provided on both sides of the moving plate 2. A turning assembly is provided on one side of the moving plate 2. An overpressure prevention mechanism for preventing excessive clamping of goods is provided on the turning assembly. A driving mechanism for driving the turning assembly to drive the goods to turn is provided inside the moving plate 2.

[0031] As Figure 1 shown, the lifting assembly includes a lifting motor 3, a reel 4, a connecting belt 5, and a guide wheel 6. Fixed plates 7 are symmetrically provided on both sides of the bottom of the back of the vehicle frame 1. The reel 4 is rotatably arranged between the two fixed plates 7. A lifting motor 3 connected to the reel 4 is installed outside the corresponding fixed plate 7. The guide wheel 6 is rotatably arranged at the top of the inner wall of the vehicle frame 1. The connecting belt 5 is guided through the guide wheel 6. One end of the connecting belt 5 is wound and connected to the reel 4, and the other end is connected to the moving plate 2.

[0032] Among them, the lifting motor 3 drives the reel 4 to rotate. During the rotation of the reel 4, the connecting belt 5 is wound and collected. During the collection process, the other end of the connecting belt 5 pulls the moving plate 2 to drive the turning assembly to move upward under the limitation of the limit member.

[0033] As Figure 1 shown, the limit member includes a limit frame 8. There are two groups of limit frames 8, both of which are in a U-shaped shape. The moving plate 2 is slidably arranged on the vertical sections of the two groups of limit frames 8.

[0034] As Figure 2 and Figure 3 shown, the turning assembly includes a rectangular plate 9, a hydraulic cylinder 10, a connecting plate 11, a fork a 12, and a fork b 13. A limit groove 14 is provided on the rectangular plate 9. The hydraulic cylinder 10 is installed in the limit groove 14. The output end of the hydraulic cylinder 10 is connected to a connecting plate 11 that is slidably connected to the limit groove 14. The fork a 12 is movably connected to the lower part of the connecting plate 11 through an overpressure prevention mechanism. The fork b 13 is installed at the bottom of the moving plate 2 and is arranged corresponding to the fork a 12. The hydraulic cylinder 10 drives the connecting plate 11 and the fork a 12 to move synchronously. During the movement of the fork a 12, it gradually approaches the fork b 13 to clamp the goods on the fork b 13.

[0035] Embodiment 2

[0036] As Figure 1-Figure 4 shown, a forklift turning device proposed by the present utility model, on the basis of the above embodiment, this embodiment also details the specific components of the driving mechanism and the overpressure prevention mechanism, as well as the connection methods between the two and the turning assembly.

[0037] As Figure 3 shown, the driving mechanism includes

[0038] A rotating shaft 15 is provided on the inner side of the movable plate 2 for transverse rotation, one end of which passes through the movable plate 2 and is connected to the rectangular plate 9;

[0039] A worm wheel 16 is provided on the rotating shaft 15, one side of which is meshed with a worm 17, and the worm 17 is vertically rotatably provided inside the moving plate 2; and

[0040] A driving motor 18 is mounted on the moving plate 2 , and an output end of the driving motor 18 passes through the moving plate 2 and is connected to the worm 17 .

[0041] The worm 17 is driven to rotate by the driving motor 18. The worm 17 meshes with the worm wheel 16 during the rotation. The meshing force drives the rotating shaft 15 and the rectangular plate 9 to rotate. The direction of clamping the goods can be changed during the rotation.

[0042] like Figure 4 As shown, the overpressure prevention mechanism includes a fixed cylinder 19, a slide plate 20, a connecting shaft 21, a pressure rod 22, a compression spring 23 and a pressure alarm 24. The fixed cylinder 19 is arranged on the top of the connecting plate 11, and the slide plate 20 is connected to the inside of the fixed cylinder 19 through the compression spring 23. The slide plate 20 is slidably connected to the inner side of the fixed cylinder 19; a connecting shaft 21 is arranged at the bottom of the slide plate 20, which passes through the connecting plate 11 and is connected to the fork a12, a pressure rod 22 is arranged on the top of the slide plate 20, and a pressure alarm 24 opposite to the pressure rod 22 is arranged on the top of the inner wall of the fixed cylinder 19.

[0043] In summary, in this embodiment, when it is necessary to clamp goods, the driving mechanism is used to adjust the direction of the rectangular plate 9 so that the forks a12 and b13 are set horizontally, and then the lifting mechanism is used to adjust the height of the movable plate 2 and the rectangular plate 9 so that the forks a12 and b13 are respectively located on both sides of the goods to be clamped, and then the hydraulic cylinder 10 controls the connecting plate 11 to move toward the fork b13. During the movement, the fork a12 is driven close to the goods, so that the goods are clamped between the forks a12 and b13. The clamping process In the process, the goods will exert the same magnitude of reverse force on the fork a12. When the reverse force is too large, it means that the clamping force it is subjected to is too large. After the fork a12 is subjected to the reverse force, it drives the slide plate 20 to squeeze the compression spring 23 through the connecting shaft 21. When the reaction force is greater than the elastic force of the compression spring 23, the slide plate 20 will be displaced under the action of the thrust, thereby driving the pressure rod 22 to squeeze the pressure alarm 24. The pressure alarm 24 will buzz, reminding the operator to make timely adjustments to avoid excessive clamping force on the goods.

[0044] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
