2) before the handling stator, cleaning stator interior and rotor surface, the diameter of axle position of laying bearing will bandage, and utilizes overhead traveling crane handling motor stator and motor stator is placed on the stator base, transfers four 50 tons of jack at the support ear of two sides of stator,
3) before the handling rotor, in the non-load side of rotor outrigger shaft is installed, length is looked motor size and is decided, and purpose is in the punching process, rotor shaft to be played a supporting role;
4) prepare punching with the crane rotor of slinging, rotor is sling the back with bar formula level meter survey axle horizontal, and rotor penetrates on the rotor pedestal of direction front end and fills up the steel pier; Pillar is built in another rotor pedestal outside by laying bricks or stones; Pillar top pad is gone up the steel pier, when rotor passes stator, the rotating shaft of rotor one end and the outrigger shaft of the other end is placed on the steel pier respectively; Guarantee that rotor and stator remain with the gap in vertical direction, be lined with sleeper between the rotor pedestal of rotor middle part and its below;
5) after rotor falls, utilize the crane stator of slinging, stator is moved to mounting center line position place, utilize crane that rotor is moved to the mounting center line position then;
6) sling rotor and moving down of crane, simultaneously, jack drives stator and falls after rise downwards, and the same moved further of stator and rotor remains with the gap all the time between them;
7) after punching finishes, rotor and stator are fixedly installed togather.
Described stator base and rotor pedestal adopt square brick to be built into.
Described cushion block adopts I-steel to process.
During punching, by the rotor load side to non-load side punching.
During punching, with the vulcan fibre pad at the stator inner hole place.
During the lifting rotor, steel wire rope and rotor position contacting are lined with vulcan fibre or Rubber washer.
Compared with prior art, the invention has the beneficial effects as follows:
The inventive method adopts the assembled in forms motor of first handling, back assembling, and easy to operate, high efficiency has alleviated the load of the each handling of crane, hangs hypodynamic problem thereby solved crane, has guaranteed to construct and has carried out smoothly.

Embodiment
A kind of roughing mill main driving motor hanging method, this method adopt the form of first handling, back assembling that the rotor 6 and the stator 4 of roughing mill main driving motor are installed, and concrete steps of the present invention are following, like Fig. 1～shown in Figure 6:
1) builds stator base 3 and rotor pedestal 1 in the installation site of motor; Stator base 3 adopts square brick to be built into rotor pedestal 1; Rotor pedestal 1 is arranged on stator base 3 both sides; Cushion block 2 is installed on stator base 3 and rotor pedestal 1 respectively, and cushion block 2 adopts I-steel to process, and cushion block 2 is through on the bolt pedestal;
2) before the handling stator 4; Cleaning stator 4 inner and rotor 6 surfaces, the diameter of axle position of laying bearing will bandage, and prevents that scratching damages in stator 4 installation processes; Prevent that pollutant from entering into stator 4 or rotor 6; Utilize crane 5 handling motor stators 4 and motor stator 4 is placed on the stator base 3, transfer four 50 tons of jack 12 at the support ear of 4 two sides of stator
3) before the handling rotor 6, in the non-load side of rotor 6 outrigger shaft 11 is installed, length is looked motor size and is decided, and purpose is in the punching process, rotor shaft 7 to be played a supporting role;
4) prepare punchings with sling rotor 6 of crane 5; Rotor 6 is sling the back with bar formula level meter survey axle horizontal; Rotor 6 penetrates on the rotor pedestal 1 of direction front end and fills up steel pier 9, and pillar 10 is built in another rotor pedestal 1 outside by laying bricks or stones, and pillar 10 top pads are gone up steel pier 9; When rotor 6 passes stator 4; The rotating shaft 7 of rotor 6 one ends and the outrigger shaft 11 of the other end are placed on respectively on the steel pier 9, guarantee that rotor 6 and stator 4 remain with the gap in vertical direction, be lined with sleeper 8 between the rotor pedestal 1 of rotor 6 middle parts and its below;
5) after rotor 6 falls, utilize crane 5 stator 4 of slinging, stator 4 is moved to mounting center line position place, utilize crane 5 that rotor 6 is moved to the mounting center line position then;
6) sling rotor 6 and moving down of crane 5, simultaneously, jack 12 drives stators 4 and falls downwards, and stator 4 and rotor 6 same moved further remain with the gap all the time between them;
7) after punching finishes, rotor 6 and stator 4 are fixedly installed togather.
In the installation process; Damage mutually for avoiding stator 4 endoporus or rotor 6 outer surfaces; During punching; Shield well with the vulcan fibre pad at stator 4 endoporus, shine to load side, so that can observe gapped sliding between punching process rotor 6 and the stator 4 by non-load side with lighting apparatus simultaneously at transmission side.During lifting rotor 6, steel wire rope and rotor 6 contact portions application vulcan fibre and Rubber washer are good, in order to avoid scratch rotor 6, and forbid on important mating surfaces such as axle journal, to lift by crane.Wherein hanging beam is suspended on crane 5 eave tiles and wants leveling.During rotor 6 liftings, must keep its level, in order to avoid thorax in wound bearing liner lining and the stator 4 with steady.
