[0031] A liftable pallet 6 is arranged inside the turntable 2. The pallet 6 rotates synchronously with the turntable 2. A conveying mechanism is arranged on the pallet 6. The conveying mechanism drives a conveying wheel 9. There are eight groups of conveying wheels 9 and their axes are parallel. The conveying wheels 9 correspond to the positions of the through grooves 20, and the conveying wheels 9 lift in the through grooves 20.

[0032] As an implementation manner in this embodiment, to control the rotation of the turntable 2, as Figures 3 to 6 shown, the output shaft of the angle motor 3 is connected to a driving gear 31 through a speed reducer 30. A synchronous ring 4 is rotatably connected to the outer side of the bottom of the circular groove. An external gear ring 41 is arranged on the outer side of the synchronous ring 4. The external gear ring 41 meshes with the driving gear 31. A collar 40 is arranged at the bottom of the synchronous ring 4. A synchronous block 42 is arranged inside the collar 40. A synchronous groove 22 is arranged on the outer side of the bottom of the turntable 2. The synchronous block 42 is adapted to the synchronous groove 22.

[0033] As an implementation manner in this embodiment, to enable the pallet 6 to rotate synchronously and be liftable in the turntable 2, as Figure 5 、 Figure 7 shown, guide blocks 21 are arranged on the inner wall of the turntable 2. Guide grooves 61 are arranged on the edge of the pallet 6. The guide grooves 61 are slidably connected to the guide blocks 21 in the vertical direction.

[0034] As an implementation manner in this embodiment, to facilitate the control of the lifting of the pallet 6, as Figure 3 、 Figure 5 shown, a lifting electric cylinder 5 is arranged at the inner bottom of the electric flat car body 1. The telescopic end of the lifting electric cylinder 5 is rotatably connected to a rotating seat 60, and the rotating seat 60 is connected to the bottom of the pallet 6.

[0035] As an implementation manner in this embodiment, to enable all the conveying wheels 9 to rotate synchronously so as to unload the goods, as Figure 3 、 Figure 4 、 Figure 7 shown, the conveying mechanism includes a double-headed motor 7, shaft seats 8 and conveying wheels 9. The double-headed motor 7 and shaft seats 8 are arranged on the pallet 6. Shaft seats 8 are arranged on the front, rear, left and right of the double-headed motor 7. A conveying shaft is rotatably arranged on the shaft seat 8. A synchronous wheel 80 and a conveying wheel 9 are arranged on the conveying shaft. The output shaft of the double-headed motor 7 is connected to the conveying shafts on the left and right sides. The synchronous wheels 80 on the conveying shafts on the left and right sides drive the conveying shafts on the front and rear sides through a synchronous belt.

[0036] As an implementation mode in this embodiment, for the convenience of the flexible movement of the electric flat car 1, as Figure 3 shown, a steering motor 11 is provided in the electric flat car body 1. The moving wheels 10 are rotatably connected to the electric flat car body 1 through wheel seats, and the output shaft of the steering motor 11 is connected to the wheel seats.

[0037] The working principle of this utility model: When loading goods, the lifting electric cylinder 5 is in a contracted state, the pallet 6 is in a low position, and the conveying wheels 9 are located below the through groove 20. After placing the goods on the tops of the electric flat car body 1 and the turntable 2, the electric flat car body 1 moves to transport the goods. During this process, the traveling direction of the moving wheels 10 can be controlled by the steering motor 11, so as to control the transportation route of the electric flat car body 1. After the goods are transported in place, according to the direction of unloading required, the angle motor 3 is started, and the driving gear 31 is driven to rotate through the speed reducer 30, driving the outer tooth ring 41 meshing with it, driving the synchronous ring 4 to rotate, and the collar 40 rotates accordingly. Through the cooperation of the synchronous groove 22 and the synchronous block 42, the turntable 2 is driven to rotate with the synchronous ring 4. At the same time, through the cooperation of the guide block 21 and the guide groove 61, the pallet 6 rotates with the turntable 2, driving the conveying wheels 9 to rotate and change the conveying direction. After the conveying wheels 9 are aligned with the unloading direction, the angle motor 3 stops rotating. Then, the telescopic end of the lifting electric cylinder 5 extends, driving the pallet 6 to rise through the turntable seat 60. The conveying mechanism on the pallet 6 rises accordingly. The conveying wheels 9 rise from the corresponding through grooves 20 and contact the bottom of the goods. Then, the lifting electric cylinder 5 stops extending and is positioned. Then, the double-headed motor 7 is started, driving the connected conveying shaft to rotate on the shaft seat 8, and driving the conveying shafts on other shaft seats 8 through the synchronous pulley 80 and the synchronous belt, so that all the conveying wheels 9 rotate synchronously. The conveying wheels 9 rotate to send the goods in contact with them to the unloading location, completing self-unloading. After that, the double-headed motor 7 stops rotating, and the lifting electric cylinder 5 contracts, causing the conveying wheels 9 to fall below the through groove 20 for loading goods again.
