Mounting machine jacking device and mounting method

The invention designs an installation machine jacking device and an installation method. The installation machine jacking device comprises a base platform and an upgrading mechanism. The base platform is a round platform, the lifting mechanism comprises a plurality of lifting stand columns, the lifting stand columns are vertically installed on the base platform, the distance between each lifting stand column and the circle center of the base platform is a first fixed value, and a hanging lifting lug is arranged at the end, away from the base platform, of each lifting stand column. An electric chain hoist is hung on the hanging lug; the electric chain hoist is used for being connected with a wall plate through a rope and controlling the wall plate to ascend and descend. The electric chain hoist is further used for keeping the wall plate standing. According to the mechanical jacking device, the wall plates are kept standing through the lifting mechanism, overturning of the wall plates is avoided, the safety of
