The invention discloses a two-section type coaxial linkage trapezoidal screw lifter which comprises an upper-section shell, a middle-section shell, a lower-section fixed shell and a base which are distributed up and down, and the upper-section shell, the middle-section shell, the lower-section fixed shell and the base are connected through a two-section type coaxial trapezoidal screw linkage device. According to the two-section type coaxial trapezoidal screw linkage device, the mode that the first screw and the second screw sleeve are in linkage when the first screw and the second screw sleeve are appropriate is adopted for working, the upper section shell and the middle section shell can sequentially ascend and descend through the spline screwing opening trapezoidal nut, the double-end screwing opening sleeve, the limiting nut sleeve and the upper stopping screwing opening sleeve, and the large-stroke linkage lifting effect is achieved; and a motor and an electric controller can be arranged at the top, so that the construction personnel can operate by one person.
本发明公开了两段式同轴联动梯形螺杆升降器,包括包括呈上下分布的上段壳体、中段壳体、下段固定壳体和底座,所述上段壳体、中段壳体、下段固定壳体和底座通过两段式同轴梯形螺杆联动装置连接。本发明两段式同轴梯形螺杆联动装采用了第一螺杆和第二螺杆套合适时联动的方式工作通过花键旋口梯形螺母、双头旋口套、限位螺母套、上止旋口套,使得上段壳体、中段壳体能依次升降,实现大行程的联动升降效果,电机和电控可以设置在顶部,因此施工人员可单人操作的结构优势。
