[0029] like Figures 5 to 7 As shown, the loading and unloading device 4 also includes a vertical plate 42 and a roller 46. The vertical plate 42 is vertically arranged on the base 41. The roller 46 is installed on the vertical lifting plate 43 through a rotating shaft. The roller 46 is in contact with the vertical plate 42. At least two rollers 46 are arranged on the front and back sides of the vertical plate 42. By arranging the vertical plate 42 and the roller 46, and clamping the vertical plate 42 by the roller 46, the lateral force received by the vertical lifting plate 43 during lifting is released to the vertical plate 42 through the roller 46, so as to avoid the lateral force causing the lifting mechanism 45 to get stuck and cause equipment failure, thereby ensuring the stability of the equipment. The lifting mechanism 45 is a hydraulic cylinder.

[0030] like Figure 8The supporting claw 44 is L-shaped, and includes a vertical short side 441 and a horizontal long side 442. One end of the long side 442 is connected to the lower end of the short side 441, and a hanging groove 443 is arranged on the back of the upper end of the short side 441. The vertical lifting plate 43 is arranged vertically, and the top thickness of the vertical lifting plate 43 is the same as the width of the hanging groove 443.

During the whole process, the goods are always on the cargo board 5. When the goods are transported, there is no need to increase the number of loading and unloading operations, thereby reducing the labor intensity.

[0033] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, this does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
