The invention provides an inner stator lifting and turnover structure. By the adoption of a structure that a small hook of a travelling crane is matched with a large hook for simultaneous lifting, the inner stator lifting and turnover structure guarantees perpendicular lifting of an inner stator; by the additional arrangement of an inclined base plate structure, the axes of two lifting bars can be located on the same straight line after the inner stator lifting and turnover structure is mounted, so that the requirement of turnover rotation is met; by the additional arrangement of a tightening structure, the inner stator is stressed with both the shearing force of bolts and the forward tightening force of the tightening device in the lifting and rotating turnover process; and therefore, the safety coefficient of the whole structure is greatly increased, and the service life of the whole structure is greatly prolonged.
