An anti-slip clamping plate 55 is threadedly connected to the surface of the bidirectional threaded rod 2 54. The two sides of the anti-slip clamping plate 55 are slidably connected to the inner side of the inner groove 52. The adjustment unit 4 includes a motor 2 41, which is bolted to the top surface of the fixed frame 21. A threaded rod 42 is fixedly sleeved at the output end of motor 41. A sliding frame 43 is threadedly connected to the surface of the threaded rod 42. The two sides of the sliding frame 43 are slidably connected inside the limiting groove 23. An electric telescopic rod 44 is installed through the sliding frame 43. The telescopic end of the electric telescopic rod 44 is fixedly connected to one side of the pressing plate 51. Motor 41 drives the threaded rod 42 to rotate, and at the same time drives the sliding frame 43 to move the pressing plate 51 downward under the limitation of the limiting groove 23. At the same time, the electric telescopic rod 44 drives the pressing plate 51 to adjust the position of the goods and make the pressing plate 51 contact the top surface of the goods. At the same time, motor 53 drives the bidirectional threaded rod 54 to rotate, and the anti-slip clamping plate 55 contacts the two sides of the goods under the limitation of the inner groove 52, thus completing the limitation and fixation of the goods. At the same time, moving the forklift chassis 1 can realize the transfer of pallets.
[0033] Example 2
[0034] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the lifting unit 2 includes a fixed frame 21, which is fixedly connected to one side of the forklift chassis 1. The fixed frame 21 has a first limiting groove 22 and a second limiting groove 23.

The bidirectional motor 26 is controlled to drive the gear 25 and the rack 24 to mesh with each other under the limitation of the moving frame 31. At the same time, the moving frame 31 is driven to drive the shovel plate 32 to lift the pallet under the limitation of the first limiting groove 22. Then, the forklift chassis 1 is controlled to remove the pallet.
[0035] Example 3
[0036] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the shoveling unit 3 includes a movable frame 31, which is rotatably connected to the output end surface of the bidirectional motor 26.

A motor 33 is bolted to one side of the movable frame 31. A bidirectional threaded rod 34 is fixedly sleeved at the output end of the motor 33. The surface of the bidirectional threaded rod 34 is threadedly connected to the inside of the shovel plate 32. The motor 33 is controlled to drive the bidirectional threaded rod 34 to rotate, and at the same time, the shovel plate 32 is driven to adjust the spacing of the shovel plate 32 according to the size of the pallet under the limiting position of the movable frame 31. At the same time, the forklift chassis 1 is controlled to move, and the shovel plate 32 is inserted under the pallet.
[0037] The working principle of this highly stable AGV forklift will be explained in detail below.
[0038] like Figure 1-5As shown, by controlling motor 33 to drive bidirectional threaded rod 34 to rotate, the lifting plate 32 is adjusted according to the size of the pallet by the moving frame 31. Simultaneously, the forklift chassis 1 is moved, and the lifting plate 32 is inserted under the pallet. The bidirectional motor 26, under the limit of the moving frame 31, drives gear 25 and rack 24 to mesh, simultaneously driving the moving frame 31, under the limit of the limiting groove 22, to lift the pallet with the lifting plate 32. Then, the forklift chassis 1 removes the pallet. The second motor 41 drives the threaded rod 42 to rotate, and at the same time drives the sliding frame 43 to move the pressing plate 51 downward under the limit of the second limiting groove 23. Simultaneously, the electric telescopic rod 44 controls the pressing plate 51 to adjust the position of the goods and make the pressing plate 51 contact the top surface of the goods. At the same time, the motor 3 drives the bidirectional threaded rod 54 to rotate, which in turn drives the anti-slip clamping plate 55 to contact the two sides of the goods under the limit of the inner groove 52, thus completing the limiting and fixing of the goods. At the same time, the pallet can be transferred by moving the forklift chassis 1.
[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
