The invention relates to the technical field of jacking equipment, in particular to jacking structures and a jacking device. According to the jacking structures, one of stepped spiral surfaces is rotated through matching of the stepped spiral surfaces, so that the contact position of the two matched stepped spiral surfaces is changed, and the axial size of the jacking structures is increased or decreased. The jacking structures are simple in overall structure, ascending and descending of a large load can be achieved in a small space, and the ascending or descending distance can be accurately controlled through a rotating angle. The jacking device comprises a plurality of jacking structures, the jacking structures are stacked in the axial direction of the jacking device, and the lifting distance is increased.

    本发明涉及顶升设备技术领域,尤其涉及一种顶升结构、顶升装置。顶升结构通过阶梯螺旋面的配合,旋转其中一个阶梯螺旋面,使相配合的两个阶梯螺旋面的接触位置发生变化,实现顶升结构的轴向尺寸的增加或减小。该顶升结构整体结构简单,可在较小的空间实现大载荷的上升和下降,并且上升或下降的距离可通过旋转角度精确控制。顶升装置包括多个顶升结构,多个顶升结构沿其轴向堆叠设置,增加升降距离。
