本発明は、回転電機のステータ片に係り、特に、その据
付用の下部吊り金具に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a stator piece for a rotating electric machine, and particularly to a lower hanging fitting for installing the stator piece.

地で一体に陣立てる方法が広く採用されている。Due to transport restrictions and manufacturing considerations, stator frames used in vertical shaft rotating electric machines are not made of one piece, but rather are made up of multiple stator frames, and the method of arranging them as one at all sites is widely adopted. has been done.
この種のステータフシームの組立例を第１図で説明する
。An example of assembly of this type of stator seam will be explained with reference to FIG.

。As shown in FIGS. 1(a) and 1(b), cranes 4 and 5 are used to attach the upper hanging bracket 2 and lower hanging bracket 3 to the stator piece 1 that has been transported horizontally. Raise the frame piece 1 as shown in FIG. 1(C).

レーム片１をベース１１の上まで運搬した状態を示す。FIG. 1(d) fl shows the stator frame piece 1 standing up. At this time, the chain block 6 and wire rope 7.8 are loosened and attached in advance as shown in Figures 1 (a) and (C), and the crane 4.5 is used to cut the metal. With stator 7V-arm piece 1 beginning to rise, gradually apply chain block 6 to
balance with 4. Once balanced, lower the crane 5 and remove the wire rope 10. FIG. 1(e) shows a state in which the V-n 4 has been moved from the state shown in FIG. 1(d) and the stator frame piece 1 has been conveyed to the top of the base 11.

強度全確保できる構造にしている。Thereafter, the stator frame piece 1 is installed on the base 11 by fully operating the hinge 4. However, in such a conventional method, if the height dimension of the lower hanging bracket 3 determined by strength calculation is larger than the height H of the base 11, the lower hanging bracket 3 is placed between the bases 11. Since the stator frame piece 1 cannot be placed on the base 11, it is impossible to install the stator frame piece 1, and furthermore, when raising the stator farm piece 1 from the horizontal position, two cranes are required. However, if there is only one hinge, there is a drawback that the stator farm piece 1 cannot be raised. Furthermore, as a method to solve these problems, as shown in FIG.
Raise it as shown in FIG. 2(C). At this time, when the upper hanging fitting 12 is lifted up by the beam V-4, the structure is such that the stator farm piece 1 can be suspended with all the strength possible using only the upper hanging fitting 12.

られない欠点があった。Lower hanging 2. As for the metal fitting 13, as shown in FIG. 2 <C>, an arcuate guide is attached to the bottom surface, and the stator firm piece 1 is raised along the guide. This method does not pose any problem in normal assembly, but with the recent increase in the size of equipment, a method of tightening the stator farm piece 1 using the lower part &30 as a foundation is often used as shown in FIG. 31. That is, the height of the equipment is lowered to increase the strength of the equipment. This structure had the disadvantage that it could not be attached with the structure of the lower hanging fitting 13 shown in FIG.

なる。As shown in FIGS. 4(a) to 4(e), the upper hanging bracket 14 is attached to the stator frame piece 1 that has been transported horizontally.
Then, attach the lower hanging bracket 15 and operate the crane 4 to raise it as shown in FIG. 4(d). In this case, the bottom of the lower hanging fitting 15 is provided with an arc-shaped guiding lip as shown in FIG. Furthermore, when the upper hanging bracket 14 is attached to the stator farm piece 1, the hanging position of the upper hanging bracket 14 and the center of gravity position of the stator farm piece 1 are Set it in a position that is A degree further away. By doing so, when the upper hanging fitting 14 is used to lift the object, it is possible to lift the object without applying any force to the tip of the lower hanging fitting 15. As for the lifting method, as shown in Figure 4 (C), operate the bow 4.
Raise stator farm piece 1. When the stator frame piece 1 is raised by the operation of the V-bond 4, the stator frame piece 1 is moved along the arcuate guide rib on the bottom of the lower hanging fitting 15, and the V-bond is moved up. It is possible to wake up even on a stand. Furthermore, the chain block and the wire rope required for it are no longer required, simplifying the structure and reducing manufacturing costs. Transportation costs can be significantly reduced.
