Abstract
The utility model provides a rigid support structure for a seat ring of a water turbine, which is characterized by comprising a ground anchor, a support seat, a threaded rod and the water turbine seat ring, wherein the support seat is welded right above the ground anchor; the lower end of the threaded rod penetrates into the support seat, and a first hold-down nut is screwed into the upper end of the threaded rod to vertically fix the threaded rod onto the support seat; a support nut and a second hold-down nut are screwed into the upper end of the threaded rod; and the water turbine seat ring is arranged between the support nut and the second hold-down nut. In the implementation process of the rigid support structure for the seat ring of the water turbine, as a foundation bolt embedding process is not needed, a concrete pouring process is reduced, thus, the installation is simple, and the construction efficiency is high. Simultaneously, the horizontal position of the water turbine seat ring is jointly adjusted through the support nut and the threaded nut, thus, the operation is simple and convenient.
Description
[technical field]
The utility model relates to a kind of hydraulic generator unit, particularly a kind of turbine stay ring rigidity supporting structure.
[background technique]
As shown in Figure 1, the turbine stay ring supporting structure adopt usually stone bolt 1 ' add wedge 2 ' the adjustment mode, in the installation process, civil engineering side builds for the first time, build a hollow knoll, then with stone bolt 1 ' and lateral pin 2 ' put into hollow concrete pier 3 '; Civil engineering side builds for the second time, and stone bolt 1 ' build is last, the concrete pier 5 that turbine stay ring 4 ' be positioned over is built ' on, regulate wedge 6 ' to adjust turbine stay ring 4 ' horizontal position; After adjustment finished, civil engineering side built for the third time, for the third time for turbine stay ring 4 ' build.Adopt this seat ring supporting structure, stone bolt just can be built turbine stay ring after need building separately.The work progress complexity, length consuming time, efficiency of construction is low.
[model utility content]
The technical problems to be solved in the utility model is to provide a kind of turbine stay ring rigidity supporting structure simple, high efficiency of construction of installing.
The utility model is achieved in that a kind of turbine stay ring rigidity supporting structure, comprise: an earth anchor, a supporting base, a screw rod, a turbine stay ring, described supporting base be welded in earth anchor directly over, described screw rod lower end penetrates supporting base, and screw in from this screw rod upper end first set screw nut with the screw rod vertical fixing on supporting base, described screw rod upper end screws in a holding nut and second set screw nut, and described turbine stay ring places in the middle of the holding nut and second set screw nut.
Described supporting base comprises seamless steel pipe and flange, described flange be welded in seamless steel pipe directly over.
There is a circular hole in described flange center, and its pore size be able to penetrate described screw rod.
Advantage of the present utility model is: the utility model is in implementation process, owing to there is not the pre-buried process of stone bolt, reduced the operation of one concreting, installation is simple and efficiency of construction is high, simultaneously, adjust the horizontal position of turbine stay ring jointly by holding nut and screw rod, simple to operation.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structural representation of background technique embodiment.
Fig. 2 is the structural representation of a kind of turbine stay ring rigidity supporting structure of the utility model.
[embodiment]
As shown in Figure 2, a kind of turbine stay ring rigidity supporting structure, comprise: an earth anchor 1, a supporting base 2, a screw rod 3, a turbine stay ring 4, described supporting base 2 be welded in earth anchor 1 directly over, described screw rod 3 lower ends penetrate supporting base 2, screw in from these screw rod 3 upper ends first set screw nut 5 with screw rod 3 vertical fixing on supporting base 2, described screw rod 3 upper ends screw in a holding nut 6 and second set screw nut 7, described turbine stay ring 4 places in the middle of the holding nut 6 and second set screw nut 7.Described supporting base 2 comprises seamless steel pipe 21 and flange 22, described flange 22 be welded in seamless steel pipe 21 directly over.There is a circular hole at described flange 22 centers, and its pore size be able to penetrate described screw rod 3.
For the first time during concreting 8, earth anchor 1 is built with concrete eight, build finish after, supporting base 2 is in the same place with earth anchor 1 field welding, then screw rod 3 is penetrated supporting base 2, screw in first set screw nut 5 from screw rod 3 upper ends, with screw rod 3 vertical fixing on supporting base 2, then screw in a holding nut 6 again from screw rod 3 upper ends, turbine stay ring 4 is positioned on the holding nut 6, by adjusting the position of holding nut 6 on screw rod 3, adjust the horizontal position of turbine stay ring 4, after adjustment finishes, screw in second set screw nut 7 again, with turbine stay ring 4 lockings.After installing, behind the position of all nuts of spot welding and screw rod handing-over, can carry out building of concrete 9 for the second time.Whole construction course can be finished the adjustment of turbine stay ring 4 horizontal positions by the position of adjusting holding nut 6, and only need twice concreting, and method of construction is simple and convenient, the efficiency of construction height.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
