The end face of 18 separate curved rod 12 be equipped with the mark post 14 that extends forward, measuring rod 18 and the total length after being added of mark post 14 with
The equal length of blade 21, in this way, can be fast and accurate by the relationship compared between blade 21 and measuring rod 18 and mark post 14
Judge 21 degree of impairment of blade.Spacing between fixture block 19 and measuring rod 18 is corresponding with the outer end thickness of blade 21.Mark post 14
Length be depending on recording the size for judging blade wind erosion situation in producer's handbook.
When detecting using detection instrument 1, measuring rod 18 is inserted into the blade that need to be detected from the outer rim side of load diffuser 2
In gap between adjacent blade, the inner arc surface 13 of curved rod 12 is resisted against the outer end of blade 21, and measuring rod 18 is along need
The blade 21 of detection extends and is bonded with the blade 21 that need to be detected, and the outer end for the blade 21 that need to be detected is located at fixture block 19 and measurement
Between bar 18, tool 1 will test by fixture block 19 and be limited on the blade 21 that need to be detected, realizes and be accurately positioned, to guarantee standard
Really detection.It will test after tool 1 is limited on the blade 21 that need to be detected, the inner ring side observation that diffuser is loaded from needs to detect
Blade and measuring rod 18 and mark post 14 between relationship, can accurately, quickly judge the wind of 21 front end of blade that need to be detected
Situation is lost, to quickly, accurately select reasonable repair method.
In order to which mark post 14 is more easily observed, as shown in figure 3, the height of the mark post 14 of the present embodiment is less than measuring rod 18
Height, to form section 17.
In order to meet the explanation for the producer's handbook recorded in background technique, the Design of length of the mark post 14 of this implementation is 1mm.
Certainly, the length of mark post 14 can be different according to the regulation of different producer's handbooks.
Sometimes it can remain some solder on the welding edge of 21 two sides of blade, cause measuring rod 18 complete with blade 21
Full fitting.In order to solve the problems, such as to be bonded completely, the cross section of the measuring rod 18 of the present embodiment is set as rectangular, so that measurement
Bar 18 can be preferably flattened on blade 21, be equipped with chamfering (in figure in the side for the plane of measuring rod 18 being bonded with blade
Chamfering is not shown), chamfering can make measuring rod avoid the solder for remaining in blade side.
Be covered with orchil on the side of measuring rod 18, to make warning alert effect, also can preferably with mark post area
It separates, the present embodiment covers orchil in the plane for being bonded with blade 21 of measuring rod 18.Measuring rod 18 with
The corresponding plane in section 17 is the plane for being bonded with blade 21, and the plane for being bonded with blade 21 is as datum level.
In order to it is more preferable, more easily use detection instrument, the present embodiment is equipped with handle on the exterior arc surface of curved rod 12
11, worker can preferably use detection instrument by holding handle 11.On handle 11, frosted processing can be also done, to increase
Frictional force.
The plane towards measuring rod 18 of the plane and fixture block 19 towards fixture block 19 of the measuring rod 18 of the present embodiment is mutual
In parallel.
In order to be more suitable for use in practice, it is preferred that the radius of the inner arc surface 13 of curved rod 12 is 154.61mm, is surveyed
The length of gauge rod 18 is 83.14mm, and the integral thickness of detection instrument 1 is 7.50mm, the height of mark post 14 and the height of measuring rod 18
Degree difference 0.5mm, the radius of the exterior arc surface of curved rod 12 is 164.61mm, and the chamfering of 18 side of measuring rod is fallen for 0.5mm
Angle.Measuring rod 18 with the connection side of the close fixture block 19 of the junction of inner arc surface 13 and fixture block 19 with inner arc surface 13
The close measuring rod 18 of junction connection side linear distance be 10.10mm, i.e., measuring rod 18 as shown in Figure 3 with it is interior
The upper junction plate of the junction of arc surface 13 and the linear distance with the lower connection side of the junction of inner arc surface 13 of fixture block 19
For 10.10mm.
The detection instrument 1 of the present embodiment is made of stainless steel material.
Detected that detection method includes the following steps using above-mentioned detection instrument:
S1: by measuring rod 18 between the blade and adjacent blade that the outer rim side insertion of load diffuser 2 need to detect
In gap, it is bonded measuring rod 18 with the blade 21 that need to be detected, at this point, the inner arc surface 13 of curved rod 13 is resisted against leaf
The outer end of piece 21, the outer end for the blade 21 that need to be detected will test tool between fixture block 19 and measuring rod 18, through fixture block 19
1 is limited on the blade 21 that need to be detected；
S2: the blade 21 that need to be detected from the inner ring side of load diffuser 2；When the front end face of mark post 14 with need to detect
The end face of blade inlet edge is concordant, can determine whether out that the leading edge for the blade that need to be detected is not damaged；When a part of mark post 14 is from needing to examine
The leading edge of the blade of survey is exposed, and can determine whether out that the leading edge for the blade that need to be detected has slight damage to can also continue to using but if having
Inclined-plane occur need to blade polishing it is flat after be further continued for using；When mark post 14 is completed to sentence from the exposing of the leading edge for the blade that need to be detected
The disconnected blade that need to be detected out must be placed under repair by way of replacing blade.
S3: circulation step S1 and S2, to complete the vaned detection of institute to load diffuser.
There is not fortuitous event to preferably guarantee to detect, first detection instrument 1 can be checked before step S1,
Check whether detection instrument 1 has the place for damage of colliding with, the damage if detection instrument 1 is collided with just needs to change intact
Detection instrument 1 is detected.
The above embodiments of the present invention is not the restriction to scope of protection of the utility model, the reality of the utility model
It is without being limited thereto to apply mode, all this kind above content according to the present utility model, according to the ordinary technical knowledge of this field and used
With means, under the premise of not departing from the utility model above-mentioned basic fundamental thought, the utility model above structure is made its
The modification, replacement or change of its diversified forms, shall fall within the scope of the present invention.
