The invention provides an auxiliary mounting device for a universal shaft of a vertical rolling mill. The auxiliary mounting device comprises a movable base, at least one pair of guide beams and an openable clamping piece, the guide beam comprises a cross beam and a vertical beam which are connected with each other, and guide grooves are formed in one side of the cross beam and one side of the vertical beam; the two ends of the clamping piece transversely move on the cross beam and longitudinally move on the vertical beam through the lifting mechanism so that the position of the universal shaft can be changed from the horizontal position to the vertical position. The invention further provides a using method of the vertical rolling mill universal shaft auxiliary mounting device. The clamping piece slides on the guide beam, one end of the clamping piece is used as the lifting end to vertically rise, and the other end of the clamping piece slides towards the lifting end, so that the cardan shaft is converted from a horizontal placement state to a vertical placement state, the horizontal and vertical state switching of the cardan shaft is realized, large auxiliary devices such as a travelling crane and a suspension device are omitted in operation, and the operation efficiency is improved. The operation difficulty is reduced, the operation steps are simplified, and the shaft replacement efficiency is improved.

    本发明提供一种立式轧机万向轴辅助安装装置,包括可移动的底座、至少一对导向梁以及可打开的夹紧件;导向梁包括相互连接的横梁和竖梁,横梁和竖梁的一侧均设置有导向槽;夹紧件的两端通过提升机构分别在在横梁上横向移动和在竖梁上纵向移动,以实现万向轴从水平至竖直的位置改变。本发明还提供了一种立式轧机万向轴辅助安装装置的使用方法。本发明通过夹紧件在导向梁上的滑动,以一端作为提升端竖直升高、另一端向提升端方向滑动的方式,将万向轴由水平放置转换成竖直放置的状态,实现万向轴的平立状态切换,在操作上省略了行车、悬吊装置等大型辅助装置,降低了操作难度,简化了操作步骤,提升了换轴效率。
