The invention relates to the field of jacking equipment, and provides a jacking system and jacking equipment, the jacking system comprises a jacking device, and the jacking device comprises a lifting platform assembly, a lead screw nut assembly, a first transition piece and a second transition piece. When the lifting platform assembly is subjected to unbalance loading of a workpiece, the lifting platform assembly can slightly swing by means of spherical matching between the two transition pieces, meanwhile, the second transition piece is movably connected with the nut and can be movably adjusted within a small range, self-adaptive adjustment of bearing stress is achieved, and therefore flexible connection is formed between the nut and the carrying table equivalently; in the jacking process, the nut only bears force in the vertical direction, the nut and the lead screw are not affected by unbalance loading of a workpiece, self-adaptive force bearing is achieved, deformation of the workpiece can be well adapted, unbalance loading of the lead screw can be avoided, unnecessary heating and abrasion of the lead screw are reduced, and the service life and precision of the jacking device are guaranteed.
本发明涉及顶升设备领域,提供一种顶升系统及顶升设备,包括顶升装置,顶升装置包括升降平台组件、丝杠螺母组件、第一过渡件和第二过渡件。当升降平台组件受到工件的偏载时,利用两个过渡件间的球面配合,升降平台组件可进行微小摆动,同时第二过渡件与螺母活动连接,可在小范围内活动调节,以实现承载受力的自适应调整,从而相当于使得螺母与载台之间形成柔性连接,在顶升过程中螺母只受到垂直方向的力,螺母和丝杠不会受到工件偏载的影响,自适应承力,能够很好地适应工件的变形,可避免丝杠受到偏载,减少丝杠不必要的发热与磨损,保证顶升装置的寿命与精度。
