Lever type cardan shaft replacing device of vertical rolling mill

The utility model provides a lever type cardan shaft replacing device of a vertical rolling mill. The lever type cardan shaft replacing device comprises a balance beam and a supporting beam which are perpendicular to each other. The balance beam is located at the lower end of the supporting beam and can be adjusted relative to the supporting beam. The universal shaft is vertically clamped at one end of the supporting beam; the balance beam is used for fixing and lifting the lifting rope; the supporting beam is made horizontal by adjusting the position of the balance beam. Through the arrangement of the balance beam and the supporting beam, the lifting rope is far away from the cardan shaft, interference of the lifting rope to workers is avoided when the workers conduct cardan shaft installation operation, and therefore the installation difficulty is simplified, centering and positioning of cardan shaft installation are facilitated, and the installation efficiency is improved. 本实用新型提供一种立轧机杠杆式万向轴更换装置，包括相互垂直的平衡梁
