The invention discloses an aligning bearing lift for a draught fan. The aligning bearing lift for the draught fan comprises a lifting ring, a positioning press plate, a press plate screw, a locking screw, a lifting point, a lifting rope, a turn buckle and a lifting beam, wherein an inner ring of the lifting ring is matched with an outer ring of an aligning bearing, one end of the positioning press plate is fixed on the lifting ring, the press plate screw is arranged at the other end of the positioning press plate, the press plate screw is corresponding to an inner ring of the aligning bearing, the locking screw passed through the lifting ring and extends inward, the lifting point is connected with the lifting beam through the lifting rope, and the turn buckle is arranged in the middle of the lifting rope. The lifting method includes the following steps: (1) screwing the locking screw tightly after the lifting tool is sleeved in the aligning bearing; (2) rough adjusting the aligning bearing to be horizontal by adjusting the turn buckle; and (3) rotating the press plate screw so as to enable the inner ring of the aligning bearing to be in a horizontal state required for assembly. The aligning bearing lift for the draught fan has the advantages of improving assembly efficiency and being convenient to install by rough adjusting levelness of the outer ring of the bearing and fine adjusting the inner ring of the bearing by adjusting the press plate screw.
