The invention relates to a jacking device with a lead screw in two-way transmission. The jacking device comprises a bottom plate and a slewing bearing; the slewing bearing is arranged above the bottomplate, at least three supporting rods are arranged between the slewing bearing and the bottom plate, the upper ends of the supporting rods are hinged to the slewing bearing, the lower ends of the supporting rods are installed on the bottom plate in a sliding mode, all the supporting rods are divided into a left group and a right group which are opposite, the supporting rods in the left group areconnected through a left screw rod pull rod; the supporting rods in the right group are connected through a right screw rod pull rod; the left screw rod pull rod and the right screw rod pull rod are opposite, and a screw rod is rotatably installed between the left screw rod pull rod and the right screw rod pull rod; and the left end of the screw rod penetrates through the left screw rod pull rod and is in right-hand threaded connection with the left screw rod pull rod, the right end of the screw rod penetrates through the right screw rod pull rod and is in left-hand threaded connection with the right screw rod pull rod, and by rotating the screw rod, the left screw rod pull rod and the right screw rod pull rod move oppositely, and the slewing bearing ascends and descends. The structure issimple and compact, and the slewing bearing ascends and descends stably.

    本发明涉及一种丝杆双向传动的顶升装置,所述顶升装置包括底板以及回转支承;所述回转支承置于底板上方,二者之间设置有至少三个支撑杆,所述支撑杆上端与回转支承铰接、下端滑动安装在底板上,所有支撑杆分成相对的左、右两组,左组的支撑杆通过左丝杆拉杆连接,右组的支撑杆通过右丝杆拉杆连接,左丝杆拉杆与右丝杆拉杆相对、之间旋转安装有丝杆,丝杆左端穿过左丝杆拉杆并与并左丝杆拉杆正螺纹连接,丝杆右端穿过右丝杆拉杆并与右丝杆拉杆反螺纹连接,所述丝杆转动,左丝杆拉杆与右丝杆拉杆相向移动,回转支承升降;结构简单紧凑,回转支承升降平稳。
