Abstract
The purpose of this utility model is that center adjustment tool, the tool are formed by adjustment bolt, fixed frame, conjunction bolt, washer when disclosing a kind of installation of hydrogenerator upper spider；When adjusting upper spider center, fixed frame is put together on out frame with conjunction bolt, washer, the threaded hole that adjustment bolt passes through on fixed frame is supported at upper bracket-arm, moves upper spider by rotation adjustment bolt, plays the role of adjusting upper spider center.The tool is corresponding with the quantity of generator upper bracket-arm, more sets are used cooperatively, generator upper spider is adjusted to all directions in the horizontal direction with meeting, solve the problems, such as that the hydrogenerator adjustment upper spider center of no concrete air cover structure is difficult simultaneously, while the tool construction is simple, easy for installation, accurate to the position adjustment at upper spider center.
Description
Technical field
The utility model relates to technical field of hydraulic generators, center tune when a kind of installation of hydrogenerator upper spider is provided
Whole tool.
Background technique
Upper spider is the important support component of hydrogenerator, bear unit rotating part radial mechanical imbalance power and
The effect of electromagnetic unbalance power, suspension-type unit still suffer from unit rotating part weight and hydraulic thrust, the rotation at center and unit
Turn center to be consistent, it is particularly significant for adjustment bearing liner stress.Upper spider generally pass through several support arm shafts to be mounted on hair
On motor stator base, to bear its axial force using out frame.When hydrogenerator upper spider is installed, in upper spider branch
It places radial jack between arm and concrete fan housing, adjusts upper spider center by adjusting jack.For no concrete air
The hydrogenerator of cover structure is difficult to adjust upper spider center, it is therefore desirable to consider suitable work since jack nowhere supports
Have to solve the problems, such as such structure unit upper spider center adjustment.
Summary of the invention
The purpose of this utility model is adjustment tool in center when disclosing a kind of installation of hydrogenerator upper spider, has knot
Structure is simple, easy for installation, the features such as being adjusted with all directions.
The technical solution of the utility model is: by adjustment bolt (1), fixed frame (2), conjunction bolt (3), washer (4) group
At；When adjusting upper spider center, fixed frame (2) is fixed on conjunction on out frame (5) with conjunction bolt (3), washer (4),
The threaded hole that adjustment bolt (1) passes through on fixed frame (2) is supported at upper spider (6) support arm.
The fixed frame (2) is steel plate weldment, and side is provided with out frame (5) fixed unthreaded hole (7) is closed, separately
Side is provided with the threaded hole (8) being used cooperatively with adjustment bolt (1).
Technical effect
Center adjusts tool when hydrogenerator upper spider is installed, and adjusting screw is by outer-hexagonal bolt, and fixed frame is steel
Plate weldment, structure is simple, meets the needs for adjusting generator upper spider horizontal direction all directions；Pass through certain power station upper spider
When installation from the point of view of using effect, conjunction bolt can accurately only be adjusted by rotation by upper spider center, solve no concrete
The difficult problem of fan housing structure hydrogenerator upper spider center adjustment.

Specific embodiment
As shown in Fig. 2, hydrogenerator upper spider install when center adjust tool, by adjustment bolt 1, fixed frame 2,
Close bolt 3, washer 4 forms.When adjusting upper spider center, fixed frame 2 is put together on into out frame 5 with conjunction bolt 3, washer 4
On, the threaded hole 8 that adjustment bolt 1 passes through on fixed frame 2 is supported at 6 support arm of upper spider, is moved by rotation adjustment bolt 1
Dynamic upper spider 6 plays the role of adjusting 6 center of upper spider.
In the present embodiment, the adjustment bolt 1 is outer-hexagonal bolt；Fixed frame 2 is steel plate weldment, one side
It is provided with and shares unthreaded hole 7 with out frame 5, the other side is provided with and the matching used threaded hole 8 of adjustment bolt 1.
Claims (2)
