Abstract
A kind of device facilitating penstock to adjust circle, comprise regular hexagon centerbody, on the upper surface of regular hexagon centerbody, the point of intersection on every both sides is provided with strut, one end of each strut is connected by End plate connections in centerbody center, the other end top of each strut is fixed with jack, is provided with column bottom each strut.What the utility model provided facilitates penstock to adjust the device of circle, and can solve and adjust circle efficiency low, the substandard problem of steel pipe roundness, simple to operate, tune circle is effective, efficiency is high.
Description
Technical field
The utility model relates to a kind of adjusting device, especially a kind of device facilitating pressure steel pipe of hydropower station and pressure vessel to adjust circle when carrying out annular attachment assembling.
Background technology
Penstock is before carrying out stiffening ring, thrust ring, support ring assembling, need to carry out tune circle to penstock, traditional method fixes a press with the both sides of a suspension steel pipe are each, this steel pipe jack is suspended on the crossbeam center be erected on the penstock mouth of pipe, rotate this suspension lifting steel pipe when operating and carry out tune circle, installation accessories simultaneously.This tune circle method, exist and adjust circle efficiency low, steel pipe roundness does not reach standard, and after finally causing annex to install, weld gap is excessive, have impact on welding quality, and Qie Xiao Mao is physical in a large number, can schedule delays when penstock makes on a large scale.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of device facilitating penstock to adjust circle, and can solve and adjust circle efficiency low, the substandard problem of steel pipe roundness, simple to operate, tune circle is effective, efficiency is high.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of device facilitating penstock to adjust circle, comprise regular hexagon centerbody, on the upper surface of regular hexagon centerbody, the point of intersection on every both sides is provided with strut, one end of each strut is connected by End plate connections in centerbody center, and the other end top of each strut is fixed with jack, is provided with column bottom each strut.
Regular hexagon centerbody is the centerbody that channel-section steel is made, and its top and bottom are provided with center bearing bracket stiffener.
Regular hexagon centerbody upper surface is equipped with checkered steel plate.
End plate connections is splice by polylith end plate the regular hexagon connector formed.
What the utility model provided facilitates penstock to adjust the device of circle, with the required central point of the penstock of circle of adjusting for benchmark, penstock is lifted on outside the entirety of regular hexagon centerbody and each strut composition, first measure the circularity of penstock, then determine each jack eject length, the circularity of adjustment penstock, can solve and adjust circle efficiency low, the substandard problem of steel pipe roundness, simple to operate, tune circle is effective, efficiency is high; Manufacture, easy for installation, cost is low, applied widely, is not only applicable to the tune circle of penstock, is also applicable to cylindrical pressure vessel and other cylindrical vessels and adjusts circle.

Detailed description of the invention
As Figure 1-5, a kind of device facilitating penstock to adjust circle, comprise regular hexagon centerbody 4, on the upper surface of regular hexagon centerbody 4, the point of intersection on every both sides is provided with strut 1, one end of each strut 1 is connected by End plate connections 9 in centerbody 4 center, and the other end top of each strut 1 is fixed with jack 6, is provided with column 2 bottom each strut 1.
The centerbody that regular hexagon centerbody 4 is made for channel-section steel, its top and bottom are provided with center bearing bracket stiffener 5.
Regular hexagon centerbody 4 upper surface is equipped with checkered steel plate 8.
End plate connections 9 is splice by polylith end plate 3 the regular hexagon connector formed.
Column 2 adopts channel-section steel to make.
Manufacturing process of the present utility model is as follows:
1, make regular hexagon centerbody 4 with channel-section steel, respectively weld a strut be made up of steel pipe 1 in the point of intersection on each both sides of centerbody 4, the length of strut 1 calculates according to the maximum elongation value of the internal diameter of penstock 7 and jack 6;
2, with End plate connections 9, one end of six roots of sensation strut 1 is connected into an entirety and fix welding 6 jack 6 at strut top block simultaneously;
3, checkered steel plate 8 is equipped with to ensure the safety of workmen at regular hexagon centerbody 4 upper surface;
4, the position dimension installed according to steel pipe annex calculates the height of column 2,6 columns is welded on the symmetric position of each strut 1, namely makes the utility model.
Use procedure of the present utility model is as follows:
With the central point of penstock 7 for benchmark, the utility model is arranged on multiple buttress 10, penstock 7 is hung outside the entirety of the utility model regular hexagon centerbody and each strut composition, first measure the circularity of penstock 7, that determines each jack 6 again ejects length, after regulating the circularity of penstock 7, each jack 6 is locked, keep each jack 6 to eject length constant, installation accessories again, annex installs, and regains each jack 6, penstock 7 is hung away, then changes the penstock that circle adjusted by next root needs.
