It is rotated using a rotating jig. (For example, Japanese Utility Model Publication No. 51-41069) However, when using a two-roller rotating jig as shown in the figure, which is the easiest to apply to various cylindrical shell structures with various diameters, the support angle θ 1 as shown in Fig. 4 is used. When , the moment in the cross-sectional direction due to the self-weight of the cylindrical shell 1 becomes M 1
becomes smaller, but the reaction force R 1 at the support point becomes larger,
Furthermore, when θ 1 is made smaller, R 1 becomes smaller, but M 1 becomes larger, and when the wall thickness t is thin compared to the diameter D of the cylindrical shell 1, there is a drawback that a dent occurs in the support part due to the seat. .

る。 FIG. 3 shows an example of a position adjustment mechanism for each of the support rollers 3, 6 and the inclined bed 4. As shown in FIG. In the figure,
7 is an electric motor (or other device that generates rotational force), 8 is a shaft supported by a bearing 20 on the horizontal bed 2 and rotated by the electric motor 7, 9 and 10 are threaded parts machined on the shaft 8, and 11 is a support roller. Fixed to 3,
12 is a female screw fixed to the inclined bed 4 and fitted to the threaded portion 10; 13 is a female screw that moves together with the inclined bed 4 and is attached to the inclined bed 4 via a gear 14; axis 15
Gears 16 and 17 are threaded portions machined into the shaft 15, and screws 18 and 19 are fixed to the support roller 6 and fitted into the threaded portions 16 and 17. When the shaft 8 is rotated by the electric motor 7 or an input, the support roller 3 is rotated from the threaded portions 9 and 10 provided on the shaft 8 through the internal thread 11 fixed to the support roller 3 and the internal thread 12 fixed to the inclined bed 4. and the inclined bed 4 are each slid in the direction of the arrow shown in the figure. Further, rotation is applied to the shaft 15 of the inclined bed 4 through the gears 13 and 14, and the support roller 6 is fixed to the support roller 6 through the screw portions 16 and 17 of the shaft 15 through the internal screws 18 and 19, respectively. It is slid in the direction of the arrow. Therefore, if the pitch of the threaded portions 9, 10, 16, 17 and the left/right distinction and the reduction ratio of the gears 13, 14 are appropriately determined, the shaft 8 can be rotated even if the diameter D of the cylindrical shell 1 varies. A constant support angle θ A ,
θ B and θ C are obtained, and the support rollers 3 and 6 circumscribe the cylindrical shell 1 in a correct circular arc to support it and rotate the cylindrical shell 1. Figure 3 shows the case where all position adjustments are made at the same time.
It is also possible to link them individually or only in part.
このような構成によれば、構造上最外支持角度

できる。 According to such a configuration, the outermost support angle θ C can be made wider structurally than before, so the bending moment in the cross-sectional direction due to the weight of the cylindrical shell is reduced, and the number of support rollers is increased, so the support point The reaction force at is also reduced. In addition, the maximum stress at the support point of the cylindrical shell is greatly reduced compared to the conventional two-roller rotating jig, and even with a large number of supporting rollers, changes in the diameter of the cylindrical shell can be easily accommodated. be able to.
