て固定子を昇降している。(Prior Art) When installing a horizontal shaft type rotating electric machine, such as a generator or an electric motor, at an installation site, adjustment work for centering is required. To adjust the height and horizontal level during this work, create a gap of the appropriate size between the platform embedded in the foundation and the leg plate of the stator frame, and stack several thin plates in this gap. A common method is to interpose a liner with a thin layer and adjust the laminated thickness of the liner. The stator frame is equipped with a jig that moves the stator frame up and down in order to insert and remove thin plates. In the large turbine generator shown in Figs. 6 and 7, this elevating device is a hydraulic or screw-type elevating device between a rod-shaped support portion 2 protruding from the side surface of the stator frame 1 and the foundation. A jack 3 is installed to raise and lower the stator.

枠１が塑性変形しないように、局部的な荷重の作
用や高応力の発生を避けねばならない。 When adjusting the installation of an electrical machine using these jigs and tools, it is necessary to avoid applying local loads and generating high stress so that the stator frame 1 has good stability against loads and does not undergo plastic deformation. .

うという難点がある。(Problem to be solved by the invention) In the adjusting device shown in Fig. 7, the jack 3 is placed outside the leg plate, so the moment is large and a large bending stress is generated at the fixed part between the support part 2 and the stator frame 1. In addition, since the support portion 2 protrudes laterally from the leg plate, there is a problem in that the packing width of the stator becomes large.

また、第８図および第９図の調整装置は、強度

上げによる不安定さや非能率的な作業を含むとい
う欠点がある。 Further, although the adjusting devices shown in FIGS. 8 and 9 do not have any problems in terms of strength or transportation dimensions, they have drawbacks such as instability and inefficient work due to the stacking of blocks 4.

さらにねじ穴を利用するジヤツキねじ方式は、
脚板のねじ部の強度を保つため脚板を異常に厚く
せざるを得ないという欠点がある。 Furthermore, the jack screw method, which uses a screw hole,
A drawback of this is that the leg plate must be made extraordinarily thick in order to maintain the strength of the screwed parts of the leg plate.
