The invention relates to the field of jacking machines, in particular to a double-lead-screw jacking mechanism which comprises a rack, nut sets, a driving belt, a driving unit and a jacking part. Thedriving unit and the two nut sets are arranged on the rack, each nut set comprises a lead screw, a nut and a driving belt wheel, the lead screws are sleeved with the nuts, and the nuts are driven by the driving belt wheels to rotate, the driving belt wheels in the two nut sets are driven by the driving belt to rotate synchronously, the driving belt is driven by the driving unit to rotate, and connecting base assemblies connected with the jacking part are arranged at the top ends of the lead screws of the two nut sets. The requirements of high stop precision, zero backlash, large load, compactstructure and the like can be met.

    本发明涉及顶升机械领域,具体地说是一种双丝杠顶升机构,包括机架、螺母组、驱动带、驱动单元和顶升件,其中驱动单元和两个螺母组设于机架上,所述螺母组包括丝杠、螺母和驱动带轮,所述螺母套装于所述丝杠上,且所述螺母通过所述驱动带轮带动旋转,两个螺母组中的驱动带轮通过一条驱动带驱动同步转动,且所述驱动带通过所述驱动单元驱动转动,两个螺母组的丝杠顶端均设有与所述顶升件相连的连接座组件。本发明能够满足高停止精度、零回程间隙、大载荷、结构紧凑等要求。
