1. be used for slinger'"'"'s method of set generator stator, it is characterized in that comprising the steps:

  • 1) adds auxilliary beam framed structure (2) and hydraulic lifting apparatus (3) on the basis of two 80 tons driving mechanisms of main building (1), namely go up the auxilliary beam framed structure (2) of bridge joint at two Crane Rails (1-1) of former driving mechanism (1), hydraulic jacking device (3) is arranged on the auxilliary beam framed structure (2);

    2) auxilliary beam framed structure (2) comprises some entablatrances (2-1), some cross sills (2-2), some longitudinal beams (2-3) and at least one shoulder pole girder (2-4);

    Entablatrance (2-1) connects cross sill (2-2) by some montants (2-5) and constitutes framework, this framework connects into the rigid frame support body by longitudinal beam (2-3), described rigid frame support body has two, and these two rigid frame support bodys connect into auxilliary beam framed structure (2) by shoulder pole girder (2-4);

    3) adopt hydraulic pressure to hang flat truck full the generator unit stator (4) of needs lifting is transported to the desired location, and make this stator (4) center over against the steam turbine line of centers of generator set;

    4) will lift by crane jack line (5) and hang up properly on by the suspension centre of lifting generator unit stator (4), start hydraulic jacking device (3) vertical-lift stator, and when this stator surpasses it fundamentally during the foot bolt height, stop to promote;

    Releasing hydraulic lifting apparatus (3) is connected with pumping plant and main console desk;

    Start the big race of driving, mobile described generator unit stator stops when generator unit stator (4) is in the on-station position top;

    Recovery hydraulic lifting apparatus (3) is connected with pumping plant and main console desk;

    When rotation adjustment generator unit stator (4) makes it consistent with direction in place, generator unit stator (4) is fallen, be placed on the platen in place.
