The four-column lead screw elevator comprises four sets of driving assemblies, the same frame mechanism is installed on the four sets of driving assemblies, an elevator frame is arranged among the four frame mechanisms, one side of the elevator frame is fixedly connected with two rectangular frames which are arranged in a non-diagonal mode, and the other side of the elevator frame is fixedly connected with the two rectangular frames which are arranged in a non-diagonal mode. Connecting rods are arranged between the other side of the lifting frame and the other two non-diagonal rectangular frames, the lifting frame is hinged to the rectangular frames through connecting rod mechanisms, and spherical thrust bearings for compensating errors are arranged in the four frame mechanisms; according to the invention, the lifting frame floats in one plane, and the application of the four spherical thrust bearings can enable the lifting frame to float in a second plane, so that the influence of the mounting error and the manufacturing error of the lifting machine on the smooth operation of the lifting machine is reduced.

    本发明公开了一种框架可浮动的四柱丝杠升降机,一包括四组驱动组件,四组所述驱动组件上安装有同一个框架机构,在四个所述框架机构之间设置有升降机架,所述升降机架一侧与两个非对角设置的矩形框架固定连接,另一侧与另两个非对角设置的矩形框架之间设置有连杆,升降机架通过连杆机构铰接设置在矩形框架上,四个所述框架机构内设置有弥补误差的球面推力轴承;本发明中,升降机架在一个平面内浮动,四个球面推力轴承的应用可是的升降机架在第二个平面内浮动,降低了升降机安装误差,制造误差对升降机运行顺畅的影响。
