The embodiment of the invention provides a jacking device for a four-way vehicle and the four-way vehicle. The jacking device comprises a plurality of jacking frames and a plurality of jacking trays, the jacking frames are coupled to a vehicle body of the four-way vehicle and slidably connected with the vehicle body in the vertical direction, the jacking trays are coupled to the jacking frames, each jacking tray of the jacking trays comprises a jacking plate and a plurality of pairs of guide shafts, each pair of guide holes comprises a first guide hole and a second guide hole, and the first guide hole and the second guide hole are communicated with each other. The section, perpendicular to the axis, of the first guide hole is circular, and the section, perpendicular to the axis, of the second guide hole is long circular, so that the paired guide shafts of the jacking plate slide in the corresponding paired guide holes in the vertical direction. Therefore, the requirement for the precision of the center distance of the guide shafts in the machining process of the jacking tray can be reduced, and the smoothness of relative sliding of the jacking tray and the jacking frame can be improved.
本公开的实施例提供了一种用于四向车的顶升装置及四向车。该顶升装置包括:多个顶升架,耦合至四向车的车体,并与车体沿竖直方向滑动连接,多个顶升托盘,耦合至多个顶升架,多个顶升托盘的每个顶升托盘包括:顶升板,以及多对导向轴,并且每对导向孔包括第一导向孔和第二导向孔,第一导向孔垂直于轴线的截面为圆形,第二导向孔垂直于轴线的截面为长圆形,以使顶升板的成对导向轴在对应成对导向孔内沿竖直方向滑移。由此,可以减少顶升托盘加工过程中对于导向轴中心距的精度的要求,提高顶升托盘与顶升架装相对滑移的流畅性。
