The invention relates to the technical field of jack auxiliary devices, in particular to a self-adaptive supporting disc for a jack. The self-adaptive supporting disc for the jack comprises a supporting seat and a disc body, the disc body is arranged at the lower end of the supporting seat, the supporting seat is used for bearing heavy objects, and the disc body is used for being connected with the jack. The supporting seat can move relative to the disc body to adjust the fulcrum position of the jack, and therefore the problems that the fulcrum position of a common jack is not changed, in the jack jacking adjusting process, lateral tension generated by the gravity of an airplane can be gradually increased along with the change of the jacking height, jack supporting is unstable, the airplane is prone to rollover, and great potential safety hazards exist are solved.
本发明涉及千斤顶辅助装置技术领域,尤其涉及一种千斤顶自适应支撑圆盘,包括支撑座和圆盘,所述圆盘设置于所述支撑座的下端,所述支撑座用于承载重物,所述圆盘用于连接千斤顶,所述支撑座能够相对于所述圆盘移动用于调节千斤顶的支点位置,解决了普通千斤顶的支点位置不变,在调整千斤顶顶升过程中,由飞机重力产生的侧向拉力会随顶升高度的变化逐渐增大,千斤顶支撑不稳定,飞机容易发生侧翻,有极大安全隐患的问题。
