The invention discloses a short-stroke high-thrust jacking mechanism and an AGV with the jacking mechanism. The mechanism comprises a bottom frame and a top frame arranged above the bottom frame in parallel. Two sets of lifting supports are symmetrically arranged between the bottom frame and the top frame in the length direction. The upper ends of the two lifting supports are rotationally connected with the top frame, and the lower ends are connected to the bottom frame. The lifting support can slide in the length direction of the bottom frame. A guide structure for limiting horizontal sliding of the lower end of the lifting bracket is arranged on the bottom frame; a driving disc is rotatably mounted in the middle of the bottom frame, and a power mechanism for driving the driving disc to rotate is configured; connecting rods are symmetrically hinged to the two radial sides of the driving disc, and the far ends of the connecting rods are hinged to the lifting supports on the same side. When the driving disc rotates, the two sets of lifting supports can be driven to move synchronously through the connecting rods, and therefore the height difference between the bottom frame and the top frame is changed. In the invention, small-height and large-thrust lifting can be achieved with the small size, and the lifting mechanism has the advantages of being compact in structure, good in reliability and the like.

    本发明公开了一种短行程大推力顶升机构及具有该顶升机构的AGV小车,包括底框和平行设置在底框上方的顶框,所述底框和顶框之间具有沿长度方向对称设置的两组升降支架,两组所述升降支架上端与顶框转动连接,下端连接至底框,并能够沿底框长度方向滑动,底框上设有限定升降支架下端水平滑动的引导结构,底框中部可转动地安装有驱动盘,并配置有带动该驱动盘转动的动力机构,驱动盘径向两侧对称地铰接有连杆,所述连杆远端铰接到同侧的升降支架上,驱动盘转动时,能够通过连杆带动两组升降支架同步运动,从而改变底框和顶框之间的高度差。本发明能够以相对较小的体积实现小高度并且大推力的抬升,具有结构紧凑,可靠性好等优点。
