Description
Technical field
The utility model belongs to power station stator auxiliary mounting tool field, more particularly to wind shield is installed under a kind of stator
Radial clearance survey tool is suitable for the installation of wind shield under some hydropower station stator.
Background technology
Some hydropower station unit air damper structure as shown in figure 5, wind shield by wind shield under wind shield, stator on stator, turn
Wind shield forms under wind shield and rotor on son.Wind shield is installed after rotor wind shield installs under stator, when installation
It is required that the radial clearance of wind shield and rotor wind shield is 9mm under stator, axial gap 4mm, axial gap can measure, but
It is radial clearance since space limits, can be measured currently without tool.
At present ensure radial clearance method be installation when in that also uninstalled one end with measuring, still
This method is that can not ensure that the gap in all places is all qualified, and can not just check radial direction completely after installation is complete in fact
Gap, this project can not also check and accept, and such installation quality is difficult to be guaranteed.
Utility model content
The purpose of this utility model is to provide wind shields under a kind of stator to install radial clearance survey tool, this tool energy
It is enough that conveniently wind shield installation radial clearance under stator is measured, it ensure that power station stator installation quality, in turn
It ensure that the safety of project.
In order to realize above-mentioned technical characteristic, what the purpose of this utility model was realized in：Wind shield under a kind of stator
Radial clearance survey tool is installed, it bends to space structure using whole one metal wire, including tail portion holds flat segments, the tail
90-degree bent forms the first bending segment after portion holds flat segments, and 90-degree bent forms the second bending after first bending segment
Section, 90-degree bent forms third bending segment after second bending segment, and the tail portion of the third bending segment is by being bent to form U
The height of type measurement head, the U-shaped measurement head is 9mm.
The wire uses steel wire or iron wire.
A diameter of 3mm of the wire.
The tail portion is held in flat segments, the first bending segment and the second bending segment be generally aligned in the same plane.
Plane where the hand-held flat segments in the tail portion and the first bending segment and the second bending segment and third bending segment place
Plane it is perpendicular.
Plane where second bending segment and third bending segment is mutually perpendicular to plane where U-shaped measurement head.
The utility model has the advantages that：
1, by above-mentioned apparatus, conveniently barge board radial clearance under wind shield under stator and rotor can be carried out
It measures, so that the installation quality of wind shield can be protected under stator, the device is fixed in Three Gorges underground power station 30F units
Practice mistake, using effect are fine in the lower wind shield installation of son.
When 2, checking and accepting, whether which can also qualified along circumferential standardized circle overall inspection radial clearance.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the utility model the first view stereo figure.
Fig. 2 is the utility model the second view stereo figure.
Fig. 3 is the first view stereo figure during the utility model use.
Fig. 4 is the second view stereo figure during the utility model use.
Fig. 5 is Hydropower Plant air damper structure figure.
In figure：Tail portion hold flat segments 1, the first bending segment 2, third bending segment 3, U-shaped measurement head 4, the second bending segment 5,
Barge board 7 under wind shield 6, rotor under stator.
Specific implementation mode
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
As shown in Figs. 1-2, wind shield installs radial clearance survey tool under a kind of stator, it is bent using whole one metal wire
Flat segments 1 are held at space structure, including tail portion, 90-degree bent forms the first bending segment 2 after the tail portion holds flat segments 1,
90-degree bent forms the second bending segment 5 after first bending segment 2, and 90-degree bent forms third after second bending segment 5
The tail portion of bending segment 3, the third bending segment 3 is by being bent to form U-shaped measurement head 4, the height of the U-shaped measurement head 4
9mm.It can be used under stator that 7 radial clearance of barge board is surveyed under wind shield and rotor by using above-mentioned survey tool
Amount, so that the installation quality of wind shield can be protected under stator.
Further, the wire uses steel wire or iron wire.By using above-mentioned wire, the cost of material is low, system
Facilitate.
Further, a diameter of 3mm of the wire.By using its structural strength of above-mentioned Assurance of Size, have
Imitate the deformation for preventing it in use.And then it ensure that its service life.
Further, in the hand-held flat segments 1 in the tail portion, the first bending segment 2 and the second bending segment 5 are generally aligned in the same plane.
Further, the tail portion holds plane where flat segments 1 and first bending segment 2 and the second bending segment 5 and the
Plane where three bending segment 3 is perpendicular.
Further, the plane and 4 place plane phase of U-shaped measurement head at 3 place of second bending segment 5 and third bending segment
It is mutually vertical.Facilitate it hand-held by using space structure.
The course of work and operation principle of the utility model：
If the width of Fig. 3-4, the U-shaped measurement head 4 of the tool are 9mm, subsequent is support section, and the tool can be made to stretch
The tool can be made to have radial and axial movable space in 7 measuring point of barge board under wind shield 6 and rotor under into stator.
The tool is protruded into from two pieces of wind shield junctions gap in the radial clearance between stator wind shield and rotor wind shield, on
Lower movement tool makes U-shaped measurement head down through the gap location, gap >=9mm if it can pass through, otherwise gap
It is unqualified, it needs to readjust wind shield.When examination, which can also be along circumferential standardized circle overall inspection radial clearance
No qualification.
Above-described embodiment is used for illustrating the utility model, rather than limits the utility model, in this practicality
In novel spirit and scope of the claims, to any modifications and changes that the utility model is made, this reality is both fallen within
With novel protection domain.
