Installation auxiliary device and installation calibration method for supporting roller of circular cooler

The invention relates to the technical field of ferrous metallurgy, in particular to an installation auxiliary device and an installation calibration method.The installation auxiliary device comprises a roller body installation auxiliary device, the roller body installation auxiliary device comprises a base and a wing plate, sinking tables are machined on the left side and the right side of the front end face of the wing plate respectively, and therefore sinking table faces are formed on the wing plate; transverse side lines and longitudinal side lines are formed on the outer edge of the sinking table; according to the auxiliary device, the symmetrical wing plate and sinking table structures are designed, sight obstacles of the inner ring stand column are avoided from the total station in the center of the circular cooler, the symmetrical sinking tables of the auxiliary device are directly observed, indirect observation of multiple measurement datum conversion can be changed into direct visual observation, so
