Accompanying drawing explanation
Fig. 1 is that this utility model is for measuring measurement apparatus one enforcement in the gap between partition board of steam turbine low-lying area nest and rotor
The structural representation of example.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, Fig. 1 is that this utility model is for measuring the measurement in the gap between partition board of steam turbine low-lying area nest and rotor
The structural representation of device one embodiment.The present embodiment for measuring gap between partition board of steam turbine low-lying area nest 1 and rotor 2
Measurement apparatus, including the length bar 3 being axially set on this dividing plate low-lying area nest 1 along dividing plate low-lying area nest 1, the axial length of described length bar 3
Match with the width of described dividing plate；Also include being located between described length bar 3 and described rotor 2 or be located at described length bar 3 with
Galvanized wire 4 between described dividing plate low-lying area nest 1.
In the present embodiment, described length bar 3 is circular rod iron, when making length bar 3, by the approximate dimensions in premeasuring gap,
Processing and fabricating grade ratio of going on a public errand wants the rod iron providing size that measurement size claimed range is less.Described galvanized wire 4 is located on
On described length bar 3, and in the part near described rotor 2, there is breach, be used for conceding space for described length bar 3 with described
Rotor 2 contacts.So benefit of design is that, when measuring gap, rotor 2 compresses downwards measurement apparatus, it is only necessary to pass through lead
Thickness after part between dividing plate low-lying area nest 1 and described length bar 3 is crushed on silk 4 and the thickness of length bar 3 are (when length bar 3 is
During circular length bar 3, then this thickness is then its diameter) summation, the gap obtaining rotor 2 with dividing plate low-lying area nest 1 can be measured, permissible
Save the consumption of galvanized wire 4.In other examples, described galvanized wire 4 can be designed as in the part near described dividing plate low-lying area nest 1
There is breach, be used for conceding space and coordinate with described dividing plate low-lying area nest 1 for described length bar 3.Its principle is similar to above, the most not
Discuss again.Described galvanized wire 4 to the major arc shape of dividing plate low-lying area nest 1, is to make length bar 3 direct with described dividing plate low-lying area nest 1 in breach
Contact, or allow length bar 3 directly contact with rotor 2, in order to measure more accurate.
In certain embodiments, described length bar 3 is rod iron, and the section of this length bar 3 is isosceles trapezoid shape, described length bar 3 court
One side to described dividing plate low-lying area nest 1 is the outer arcuate face that the intrados with described dividing plate low-lying area nest 1 matches；Described galvanized wire 4 level
It is arranged at the end face of described length bar 3.So so that the structure of described measurement apparatus is simpler, it is not necessary to make galvanized wire 4 be looped around length bar
On 3, galvanized wire 4 is looped around on length bar 3 and to consider to reserve breach, it is not necessary to bore calculating breach etc. work.
The measurement apparatus in the gap for measuring between partition board of steam turbine low-lying area nest 1 and rotor 2 of the present utility model, is used for
Before dividing plate is installed, first measure the gap between dividing plate low-lying area nest 1, adjust their centrage according to this gap, make in them
Heart line is positioned on the same line as far as possible.Specifically used principle is as follows: is placed in by length bar 3 on dividing plate low-lying area nest 1, is then put by galvanized wire 4
On described length bar 3, the length direction of length bar 3 is the most identical with dividing plate low-lying area nest 1, makes length bar 3 directly connect with dividing plate low-lying area nest 1
Touch, then rotor 2 is compressed downwards, after unclamping, directly directly measure by pressing lead wires 4 the thinnest with slide gauge or spiral micrometer
Place, it is possible to reach the purpose of clearance measurement.This measurement apparatus is simple and practical, and certainty of measurement is high, it is thus achieved that good warp
Ji benefit and social benefit, have extraordinary promotional value.Various gap can be generally applicable to relatively big, and prescription is high
Occasion.
These are only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every profit
The equivalent structure made by this utility model description and accompanying drawing content or equivalence flow process conversion, or directly or indirectly it is used in it
The technical field that he is correlated with, is the most in like manner included in scope of patent protection of the present utility model.
