Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, like reference characters designate the same or similar parts throughout the several views.

Fig. 1 is a schematic structural diagram of a mechanical jacking mechanism according to an embodiment of the present invention, and as can be seen from fig. 1, the mechanical jacking mechanism of the truck includes a jacking motor 110, a driving sprocket 150, a driven sprocket 170, and a cam 140. The jacking motor 110, as a driving element of the mechanical jacking mechanism, may be fixed by a motor bracket or directly mounted on the frame of the truck. The driving sprocket 150 is supported by a first support shaft 160 and is driven by an output shaft of the jacking motor 110. The driven sprocket 170 is supported by the second support shaft 180, and the driven sprocket 170 and the driving sprocket 150 are driven by a chain. The cam 140 is further driven by the driven sprocket 170 to rotate, and can rotate synchronously with the driven sprocket 170, and the outer contour of the cam 140 can contact with the tray 130, so that the cam 140 can drive the tray 130 to move up and down under the rotation motion. When the tray 130 needs to be lifted, the output shaft of the lifting motor 110 drives the driving sprocket 150 to rotate, so that the driving sprocket 150 drives the driven sprocket 170 to rotate through the chain, the cam 140 and the driven sprocket 170 rotate synchronously, and the cam 140 drives the follower to move in a plane perpendicular to the rotating shaft of the cam 140 when rotating around the fixed shaft. In this mechanical jacking mechanism, the tray 130 acts as a follower of the cam 140 mechanism, which effects an elevating motion upon rotation of the cam 140.

Preferably, the driving sprocket 150 is rotatable in synchronization with the output shaft of the jacking motor 110. In addition, in order to achieve the synchronous rotation of the driving sprocket 150 and the output shaft of the jacking motor 110, the driving sprocket 150 may be fixed to the output shaft of the jacking motor 110, that is, the first supporting shaft 160 for supporting the driving sprocket 150 and the output shaft of the jacking motor 110 are the same shaft or connected through a coupling. Further, the circumferential fixing mode of the chain wheel can adopt key connection, and the axial fixing mode can adopt a shaft shoulder, a shaft end retainer ring and the like. It should be understood that if it is desired to achieve synchronous rotation of the driving sprocket 150 and the output shaft of the jacking motor 110, in addition to using the output shaft of the jacking motor 110 as the fixed shaft of the driving sprocket 150, a transmission mechanism may be provided between the output shaft of the jacking motor 110 and the first support shaft 160 of the driving sprocket 150, but it should be noted that the transmission ratio of the transmission mechanism is conventionally set to ensure 1: 1. The situation that the transmission mechanism is additionally installed between the output shaft of the jacking motor 110 and the first support shaft 160 is applicable to the situation that the reserved installation space of the jacking motor 110 is not large, and at this time, the output shaft of the jacking motor 110 may be vertically arranged with the first support shaft 160; the transmission mechanism between the output shaft of the jacking motor 110 and the first support shaft 160 can be used to change the rotation direction of the driving sprocket 150; for example, the transmission mechanism for changing the transmission direction may be a bevel gear transmission mechanism.

In addition, the output shafts of the driving sprocket 150 and the jacking motor 110 are not limited to rotate synchronously, but only the output shafts ensure that the output shafts drive the driven sprocket 170 to rotate through a chain, and the rotation of the cam 140 ensures that the tray 130 can move up and down according to a desired movement law.

Fig. 2 is a top view of a truck to which an embodiment of the mechanical jacking mechanism of the present invention is applied, and as can be seen from fig. 2, the tray 130 is a rectangular tray 130 in a long strip shape. And the number of the tray 130 is two, and the two trays 130 are arranged in parallel and in the same plane. Specifically, the entire frame 100 of the transportation vehicle may have a rectangular parallelepiped structure, and the two trays 130 may be symmetrically disposed with respect to a center plane of the rectangular parallelepiped frame 100. During the operation of the truck, when the goods needs to be lifted, the lifting motor 110 drives the cam 140 to rotate through the chain transmission mechanism, and the tray 130 and the goods on the tray 130 are used as the followers of the cam 140 mechanism, so that the tray is lifted along with the rotation of the cam 140 until the tray is lifted to the state shown in fig. 3 and 4; similarly, when the goods need to be lowered, the jacking motor 110 continues to rotate, so that it continues to rotate the cam 140 through the chain transmission mechanism, so that the tray 130 and the goods are lowered along with the rotation of the cam 140. It should be understood that the specific structural form of the cam 140 should not be specifically limited, and may be a disc cam, a cylindrical cam, or the like; and the outer contour shape of the cam 140 depends on the motion rule of the follower (tray 130), therefore, the outer contour curve of the cam 140 can be designed according to the lifting motion stroke of the tray 130. In addition, after the structure of the cam 140 is determined, the purpose of controlling the elevating movement of the follower can be achieved by controlling the rotation speed and the rotation angle of the jacking motor 110.

Further, the number of the cams 140 may be four, and four cams 140 are respectively disposed at positions near both ends of the two bar-shaped trays 130. When the two trays 130 are symmetrically arranged, the four cams 140 can be regarded as two sets of cam mechanisms symmetrically arranged with respect to the central plane of the rectangular parallelepiped frame 100, each set of cam mechanism includes two cams 140, as shown in fig. 1, the two cams 140 of each set of cam mechanism are respectively located at positions close to the end portions of the strip-shaped trays 130; when the truck is used in the lateral direction as a traveling direction, the two cams 140 for lifting up the respective trays 130 at this time can be regarded as front side cams and rear side cams. In addition, in order to ensure that the moving speed and the moving limit of the two trays 130 are the same, the outer contour structure of the four cams 140 should be ensured to be the same.

Further, in the case of four cams 140, the number of the driven sprockets 170 is also four, and the four driven sprockets 170 are correspondingly supported by four second support shafts 180, the second support shafts 180 preferably being fixed to the frame. And in order to ensure the synchronous rotation of the cam 140 and the driven sprocket 170, the cam 140 may also be supported by the support shaft of the driven sprocket 170, that is, the cam 140 is fixed to the second support shaft 180 corresponding thereto. Illustratively, the driven sprocket 170 can be keyed to achieve circumferential securement and can be secured axially by a shoulder, a shaft end retainer ring, or the like. And the cam 140 and the driven sprocket 170 may be secured in the same or similar manner.

For a mechanical jacking mechanism with four cams 140 and four driven sprockets 170, the driving sprocket 150 can be disposed near the middle of the rectangular parallelepiped frame 100, and the driving sprocket 150 drives the four driven sprockets 170 to rotate synchronously via a chain. In order to save the number of the driving sprockets 150, two driven sprockets 170 of the truck at the front side may be supported by a support shaft, and an auxiliary sprocket may be provided at a position near the middle of the support shaft, so that a chain may be provided between the driving sprocket 150 and the auxiliary sprocket, and between the two driven sprockets 170 at the front side and the two driven sprockets 170 at the rear side, respectively, to realize a chain transmission. However, it should be understood that the specific position of each sprocket, the arrangement of the chain between the sprockets, and the like, are not particularly limited as long as the chain transmission is realized.

In an embodiment of the present invention, the bottom of the tray 130 is provided with a supporting portion 120, an outer contour of the supporting portion 120 is a curved surface, and the supporting portion 120 is always in contact with an outer contour of the cam 140. The supporting portion 120 may have other structures besides the curved outer contour, such as a roller follower, a pointed follower, a flat plate follower, etc.

In addition, the transportation vehicle further comprises a walking drive system, and the walking drive system specifically comprises a walking motor 210, a transmission mechanism and wheels 220. The traveling motor 210 is fixed to the frame 100 of the truck by a motor bracket, similar to the lift motor 110, and the wheel 220 is further fixed to the frame 100 by a wheel 220 supporting shaft. As shown in fig. 2, the number of the wheels 220 may be eight, eight wheels 220 are symmetrically disposed on two sides of the rectangular parallelepiped frame 100, the two symmetrically disposed wheels 220 are driven and fixed by a same shaft, and the driving mechanism may be preferably a chain driving mechanism. The embodiment of the present invention provides a two-way truck, but it should be understood that a four-way truck can be adopted similarly to a two-way truck.
