DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating electric machine, and more particularly to a moving device for a rotating electric machine for adjusting the position of a rotating electric machine such as a middle-capacity generator or electric motor while adjusting its position.

[0002]

2. Description of the Related Art FIGS. 4 and 5 show external views of a horizontal rotating electric machine mounted on a base plate on a foundation. FIG. 4 is a side view of the horizontal rotating electric machine, and FIG. 6 is an enlarged perspective view of a portion P in FIG. In FIG. 6, the fastening bolts shown in FIGS. 4 and 5 are omitted. As shown in FIGS. 4 and 5, the rotating electric machine installed on the base plate 5 on the foundation 7 has a stator frame 11.
Of the rotor 13 and the bearing stand 12 of the rotor 13 are integrally supported on the rectangular bed 4. To install the rotating electric machine on the foundation 7, first, the rotating electric machine supported on the bed 4 is supported by hanging wires (not shown) on the hanging lugs 6 provided at the four corners thereof.
It is carried out by hanging it over, and then tightening it with bolts 8 embedded in the foundation 7 after the positioning described later. The hanging ear 6 is, as shown in FIG.
Reinforcing beam 4 between upper plate 41 and lower plate 42 constituting platform 4
It is formed on a part of a reinforcing plate similar to 3 and 44.

The positioning for mounting the rotary electric machine at a predetermined position on the base 7 is performed by moving the bed 4 lowered on the base plate 5 in a horizontal direction by a moving device. As shown in FIG. 6, this moving device comprises moving jigs 101 and 102 provided at two places on the base plate 5 corresponding to four mutually orthogonal side surfaces of the four corners of the rectangular base 4. The moving jigs are provided at eight corners at four corners of the bed 4. These moving jigs 101 and 102 are mounted on receiving stands 52 and 53 projecting from the end surface of the lower plate 42 of the platform, and are mounted on supporting stands 11 and 12, and penetrate the supporting stands 11 and 12. Bolt 2 that is inserted into the screw hole and abuts on the side of base 4
By rotating the bolts 21 and 22, the side surfaces of the bed 4 are pushed, and the bolts 21 are mounted in the axial direction of the rotating electric machine, and the bolts 22 are mounted in a horizontal direction orthogonal to the axial direction. The floor 4 can be moved.

[0004] Incidentally, the movement of the platform 4 by the bolts 21 and 22 is performed by the side surface of the reinforcing plate 45 for reinforcing the lower plate 42 of the platform 4 and the reinforcing beam provided in contact with the reinforcing plate 45. This is performed by bringing the tips of the bolts 21 and 22 into contact with the surface of the bolt 43. Further, the bolt 8 shown in FIGS.
The through hole of the base 4 through which the base plate 4 penetrates is formed large in advance so as not to contact the bolt 8 when adjusting the position of the base 4.
Accordingly, the mounting of the bed 4 on the base plate 5 on the foundation 7 is fastened and fixed to the bolt 8 via the washer 9.

[0005]

In the above-described position adjustment of the rotating electrical machine using the moving device including the moving jigs 101 and 102, the moving jigs 101 and 102 can move only in one direction. To move the entire bed 5 in one direction in parallel, two moving jigs 101 and 102 are required on the same side of the bed 5. As described above, as shown in FIG.
The moving jigs 101 and 102 need to be provided.

That is, as many as eight moving jigs 101 and 102 are required at the time of position adjustment at the time of installation of one rotating electric machine, there is a problem that the man-hours and cost for manufacturing these moving jigs 101 and 102 increase. Was. Further, the moving jig 101,
The base plate 5 on which the base 102 is mounted is, as described above,
In order to provide 2, 53, the size becomes larger than the bed 4
There is a problem that the manufacturing cost of the base plate 5 increases and the installation area of the rotating electric machine also increases.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems by providing a moving device having a smaller number of moving jigs than in the prior art, thereby reducing man-hours and cost for manufacturing the moving jig and reducing the required area of the base plate. An object of the present invention is to provide a moving device for a rotating electric machine that can be reduced in size.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a rectangular rotating electric machine having hanging ears at four corners by using a plurality of moving jigs provided on a base plate on a foundation.
Press Jo platform floor in the horizontal direction, the movement of the rotary electric machine to install a rotary electric machine in position on the base plate, wherein
Move the moving jig near the hanging ear and rotate in the horizontal plane
Mounting on the base plate as possible, and
Change the direction of the bed to the two orthogonal directions, and
They should be pushed together.

[0009]

According to the present invention, the moving jig provided on the base plate is placed in a horizontal plane.
With one moving jig to rotate the rotating electric machine.
The rotating electric machine is moved in two directions, an axial direction and a direction orthogonal to this.
Make it possible. Thus, the number of moving jigs can be reduced, and the area of the base plate on which the moving jigs are installed can be reduced. In addition, moving jigs
Place it near the ears normally provided on the platform for lifting.
By placing the hanging ears on one of the abutting members of the moving jig
And the structure of the pedestal can be simplified.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments.
1 to 3 are partially cutaway views of a base plate and a base plate provided with a moving jig according to an embodiment of the present invention. FIG. 1 is a plan view, FIG. 2 is a front view, and FIG. FIG. 6 is a plan view in which the moving jig is rotated by 90 degrees. 1 to 3 are conventional FIGS.
This corresponds to FIG. 6, and the same parts as those in the related art are denoted by the same reference numerals, and detailed description is omitted. The moving jig 10 shown in FIG. 1 is located near the lug 6, and
1 is installed. The tip of a bolt 2 inserted into a screw hole provided through the support base 1 is brought into contact with a side surface of a reinforcing plate 45 provided on the base 4, and the base 2 is rotated by rotating the bolt 2. Can be moved in a direction orthogonal to the axial direction of the rotating electric machine. Support base 1 with bolt 2 inserted
Is provided with a protrusion 3 at the bottom thereof, and the protrusion 3
The moving jig 10 is loosely fitted in the provided hole,
It is rotatably mounted on the plate 5.

Next, as shown in FIG.
0 is rotated 90 degrees about the projection 3 so that the tip of the bolt 2 of the moving jig 10 comes into contact with the side surface of the lug 6 for lifting the bed 4 with a wire. As a result, unlike the related art (FIG. 6), in order to move the bed 4 in the axial direction of the rotating electric machine, the rotating electric machine can be moved in two directions by one moving jig 10 without separately providing the moving jig 102. It can be moved and adjusted.

[0012]

As described above, in the present invention, the transfer
The jig can be rotated in the horizontal plane by positioning it near the ears
And the moving jigs are
While changing the two directions to intersect,
By alternately pushing to adjust the position of the rotating electric machine, it is possible to move the platform in two directions, that is, the axial direction of the rotating electric machine and the direction perpendicular to the rotating electric machine with one moving jig. As a result, the number of the moving jigs can be reduced from eight to four, the man-hour and cost of manufacturing the moving jigs are reduced, and the area of the bed on which the moving jigs are installed is small. Therefore, the cost of the base plate can be reduced, and the lug for lifting the base plate can be used as one contact member for moving the rotating electric machine, so that the structure of the base plate can be simplified.
