Detailed Description
In order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the present utility model easy to understand, the following further describes how the present utility model is implemented with reference to the accompanying drawings and the detailed description.
Referring to fig. 1 to 3, the utility model provides a semitrailer with a double-layer push plate, which comprises a box body 10, and a lower-layer push plate 1, an upper-layer push plate 2, a lower-layer oil cylinder 3 and an upper-layer oil cylinder 4 which are arranged in the box body 10; the bottom surface of the lower push plate 1 is arranged on a slideway at the bottom of the box body 10; one end of the lower layer oil cylinder 3 is connected with the front end upright post 5 of the box body 10, the other end of the lower layer oil cylinder is connected with the lower layer push plate 1, and the lower layer oil cylinder 3 is used for pushing the lower layer push plate 1 to slide along a slideway at the bottom end inside the box body 10; the whole upper layer push plate 2 is positioned above the lower layer push plate 1, and the lower parts of the left side surface and the right side surface of the upper layer push plate 2 are arranged on the sideslip channel 6 on the inner side surface of the box body 10; one end of the upper layer oil cylinder 4 is connected with the lower layer push plate 1, the other end is connected with the upper layer push plate 2, and the upper layer oil cylinder 4 is used for pushing the upper layer push plate 2 to slide along the sideslip channel 6.
Preferably, the section of the lower push plate 1 is L-shaped, and has a bottom surface in the horizontal direction and a vertical surface facing the front end of the box body 10; the upper layer oil cylinder 4 is connected with the vertical surface of the lower layer push plate 1; the lower layer cylinder 3 passes through a preset opening on the vertical surface of the lower layer push plate 1 and is connected with a connecting mechanism 7 protruding above the bottom surface of the lower layer push plate 1. With reference to fig. 1, by such a structure, the positions of the two cylinders in the left-right direction are substantially overlapped, so that the two cylinders are prevented from occupying excessive space in the case 10 and from affecting the loading of the case 10.
Preferably, the top end of the upper layer push plate 2 is also matched with the top slideway 8 at the top end inside the box body 10, and the upper layer push plate 2 is limited by the top slideway 8 and the side slideway 6 at the same time when sliding. Through such a structure, the stability of the upper push plate 2 during operation is ensured. In addition, the structure of the upper layer push plate 2 can be similar to that of the push plate of the existing semitrailer with a single oil cylinder and a single push plate, and the cargo in the box body can be effectively pushed out.
