When the first bed plate is lifted to a certain height, the first bed plate can be fixed with the first compartment frame to avoid the first bed plate from shaking in the compartment body 2 during driving, thereby affecting the safety in the compartment body 2.
[0064] After the first bed plate is fixed with the first compartment frame, the first connecting joint can be detachably connected with the goods in the open-top cargo compartment 1. When the second winch 61 rotates, the length of the second steel cable 63 between each first connecting joint and the second winch 61 can be increased or decreased. When the length of each second steel cable 63 is increased, the goods can be lowered. When the length of each second steel cable 63 is decreased, the goods can be lifted or each first connecting joint can be moved upward. The first driving device 3 is started to make each wheel 7 contact the ground. Then, the connection between the compartment body 2 and the open-top cargo compartment 1 is disconnected. After that, the second driving device 6 is started to lift the goods from the open-top cargo compartment 1 and away from the bottom of the open-top cargo compartment 1. The compartment body 2 is driven or moved, and the goods are moved together with the compartment body 2 to a proper position. The goods are lowered by the second driving device 6. In the same way, the goods at a certain position can be carried into the open-top cargo compartment 1, thereby realizing the carrying or transferring of the goods.
[0065] Embodiment 2
[0066] In this embodiment, the structures of the first folding plate 41 and the second folding plate 43 on the first extension compartment 4 are different from those in Embodiment 1, and are as follows:
[0067] The first folding plate 41 and the second folding plate 43 are installed on the first compartment frame, one side of the first folding plate 41 is hinged to the third side plate 23, and the other side opposite to the first folding plate 41 is detachably connected to the first extension side plate 42; one side of the second folding plate 43 is hinged to the first side plate 21, and the other side opposite to the second folding plate 43 is detachably connected to the first extension side plate 42, that is, the two ends of the first extension side plate 42 are respectively detachably connected to the first folding plate 41 and the second folding plate 43, and the upper end of the first extension side plate 42 is slidingly connected to the fourth side plate 24. When the first extension compartment 4 is unfolded, the fourth side plate 24 is first folded upward to the highest position or a proper position, and then the first extension side plate 42 is pushed outward to gradually move away from the third side plate 23 and the first side plate 21 until a predetermined position, at which the distance between the first extension side plate 42 and the third side plate 23 or the first side plate 21 matches the width of the first folding plate 41 or the second folding plate 43, and then the first folding plate 41 and the second folding plate 43 are respectively folded outward and connected to the first extension side plate 42, so that the first extension compartment 4 can be unfolded and used. When the unfolded first extension compartment 4 is folded, the first folding plate 41 and the second folding plate 43 are first separated from the first extension side plate 42 and folded inward, and are connected to the first extension bottom plate 44 which is folded inward in advance, and then the first extension side plate 42 is driven to slide relative to the fourth side plate 24 and move inward until the distance between the first extension side plate 42 and the first folding plate 41 or the second folding plate 43 is the smallest or the first extension side plate 42 is connected to the first folding plate 41 or the second folding plate 43, and then the fourth side plate 24 is driven to fold downward until the distance between the fourth side plate 24 and the first extension side plate 42 is the smallest or the fourth side plate 24 is connected to the first extension side plate 42, so that the folding of the first extension compartment 4 can be realized. The structure and the connection mode thereof can reduce the distance between the first extension side plate 42 and the first extension bottom plate 44 after folding, and further reduce the overall width of the compartment body 2 after folding, thereby saving the space occupation.
