Background
Large motors with mass of tens of tons are widely applied to factory and mine production, and the mass and the volume are very large, so that the hoisting, dismounting and maintenance difficulty is far higher than that of common small motors.
Reach the modern mine in certain scale, its main and auxiliary well lifting machine mostly matches the large-scale motor of thousands of kilowatts, and mostly adopt the transmission mode of cylinder main shaft direct-coupled machine, this transmission mode does not have mechanical reduction gears, cylinder main shaft cantilever direct-coupled motor rotor, motor rotor adopts the hydraulic expansion inner circle mode to cramp firmly on cylinder cantilever axle, the rotor dress back, basically undetachable, motor stator passes through bolt fixed mounting on a ordinary basic base, this type of basic base only plays the effect of fixed mounting stator, no other extension functions. The motor runs for years, faults similar to stator winding grounding and the like are difficult to avoid, and in order to solve the field maintenance problem, the stator and the rotor of the motor must be separated. The method of breaking away from generally uses the driving a vehicle to hoist the stator and outwards move, but hangs and moves the degree of difficulty greatly, mainly reflects in: 1. the field crane generally cannot hoist the whole stator, the stator must be split into an upper part and a lower part which are respectively hoisted, and a certain damage risk is brought to a coil inside the motor in the process of splitting the stator. 2. When the lower half part of the stator is hoisted, because the stator coil of the lower half part is positioned under the rotor coil and is separated by a distance of only a few millimeters, the hoisting height and the moving-out process are extremely difficult to control, once the stator touches the rotor to damage the rotor coil, the motor can not be repaired on site basically, and the mine production is influenced greatly.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The foundation base for mounting the large motor stator is characterized by comprising an upper panel 1, wherein a longitudinal rib plate 2 is fixedly welded at the bottom of the upper panel 1, one end of the longitudinal rib plate 2 is fixedly welded on a bottom plate 4, a transverse rib plate 3 is also fixedly welded between the upper panel 1 and the bottom plate 4, the bottom plate 4 is fixedly mounted on a concrete foundation ground 12, a motor stator 5 is fixedly mounted on the upper panel 1, the motor stator 5 comprises an upper stator half part 51 and a lower stator half part 52, a motor rotor 6 is mounted on the motor stator 5, a main shaft 7 is mounted on the motor rotor 6, supports 8 are respectively arranged at two ends of the upper panel 1, threaded through holes are formed in the supports 8, an external threaded ejector rod 9 is connected to each support 8, and the external threaded ejector rod 9 is matched with the threaded through holes, the motor stator 5 is fixedly connected with the upper panel 1 through a fastening screw 10.
Preferably, the upper panel 1 is provided with a sliding groove 11, and the sliding groove 11 is matched with the bottom of the lower half portion 52 of the stator. The lower half part 52 of the stator is provided with a mounting edge 53, and the fastening screw 10 is mounted on the mounting edge 53.
The utility model discloses the base is installed respectively to stator the latter half 52's both sides, upper panel 1 welds into whole through longitudinal rib board 2 and horizontal gusset 3 and bottom plate 4, and bottom plate 4 is pre-buried to concrete foundation ground 12 in, and upper panel 1 processing has spout 11, with the higher smooth finish of 11 surface designs of this spout, fixes stator the latter half 52's bottom plate in spout 11 through fastening screw 10.
