Vertical hydro-generator rotor hoisting auxiliary device and hoisting method

The invention discloses a vertical hydro-generator rotor hoisting auxiliary device and a hoisting method and aims to provide the vertical hydro-generator rotor hoisting auxiliary device and the hoisting method which not only can effectively reduce the number of workers required in the hoisting process of a vertical hydro-generator rotor and improve the hoisting efficiency, but also can effectivelyavoid the problem of contact between the rotor and a stator in the hoisting process of the vertical hydro-generator rotor. The vertical hydro-generator rotor hoisting auxiliary device comprises an annular mounting piece, a plurality of glass flat plates arranged around the outer side of the annular mounting piece, a connecting piece for connecting the glass flat plates and the annular mounting piece, magnets arranged on the annular mounting piece and laser range finders arranged on the glass flat plates in a one-to-one correspondence mode. An arc-shaped datum line is arranged on each glass flat plate, laser beams emi
