Trying out in the manufacturing of some hydropower station internal pressure steel pipe is installed, effect is very good, and is convenient and practical, guaranteed penstock manufacturing installation and welding quality.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Among the figure: interior hub 1, the first support bar 2, connecting bolt 3, the second support bars 4, the three support bars 5 are regulated support bar 6, penstock 7, termination support bar 8, limited block 9, circumferentially connecting plate 10 connects shaped steel 11, holds out against nut 12, screw 13, through hole 14, double-screw bolt 15.
The specific embodiment
In Fig. 1, a kind of penstock circularity is adjusted and bracing or strutting arrangement, comprises interior hub 1, is provided with many by the support bar assembly of circumferential arrangement at the excircle of interior hub 1; Interior hub 1 is welded by the shaped steel assembly unit, and the support bar assembly is welded on the excircle of interior hub 1.
In Fig. 2, described support bar assembly is comprised of three sections support bars at least, comprises the support bar that is connected with interior hub 1, is positioned at the termination support bar 8 that the termination contacts with penstock 7, connects the adjusting support bar 6 of support bar and termination support bar 8;
