Description
Technical field
The present invention relates to a kind of detecting tool and detection method more particularly to a kind of fastener heightening base plate under iron base plate sizes
Detecting tool and detection method.
Background technique
WJ8 type fastener is by screw spike, plain washer, spring, Insulation rail distance keeper, gauge apron, railway rail pad (rubber mat plate
Or compound backing plate), iron chair, resilient sleeper-bearing and service sleeve composition under iron chair, may also include and finely tune backing plate and iron pad under rail
Height adjusting cushion plate under plate.
Since high-speed railway requires very stringent, foundation structure and the complexity of material under sleeper line to orbital forcing,
Generation can generate inhomogeneous deformation, so as to cause rail level longitudinal irregularity, and since construction error also results in track not
Smoothly.Train high speed causes " jolting " when passing through irregularity section, influences the comfort taken, or even threatens train operation peace
Entirely, it needs to be adjusted the ride comfort of rail at this time.In general, construction department can be encased inside difference according to the deformation data of rail level
The method of backing plate and heightening base plate under iron base plate is finely tuned under thickness rail to adjust the height of rail surface to guarantee the flat of rail surface
It is pliable.
Fastener heightening base plate under iron base plate is as an important spare part in WJ8 fastener, mainly adjustment rail height
And playing the role of vibration and noise reducing, the critical size of heightening base plate under iron base plate directly affects the service performance of product.
As depicted in figs. 1 and 2, fastener heightening base plate under iron base plate include arc sections 1, it is angularly disposed in 1 one end of arc sections
On shoulder block plate 2 and the level board 3 that is horizontally set in 1 other end of arc sections, arc sections, shoulder block plate and level board be one
Structure, waist typed through hole 4 is also provided on level board 3.Intersection point A between the outer inclined-plane of shoulder block plate and the bottom surface of level board is to waist
The distance between 4 central point B of type through-hole D be fastener heightening base plate under iron base plate center away from.Center is that must control away from D
In certain margin of tolerance, still, in the fabrication process, due to being influenced by various factors, ruler of the center away from D will cause
Very little error.Therefore, it must be detected before product export.
Authorization Notice No. is 201811702 U of CN, and authorized announcement date is that the Chinese utility model on April 27th, 2011 is public

Occur between the outer inclined-plane of shoulder block plate at the lower end of outer a side gap and
Occur gap between the outer inclined-plane of shoulder block plate at the upper end on other side side for observing interior angle four, interior angle four it is another
When fitting closely between the outer inclined-plane of shoulder block plate at the lower end of outer a side, then medial angle qualification is determined；Conversely, then determining not
It is qualified.
12. detection method according to claim 7, it is characterised in that: the fastener heightening base plate under iron base plate size
Detecting tool further includes go-no go gauge, and the go-no go gauge includes that connecting plate, the backing plate being arranged on connecting plate side one and setting exist
Backing plate two in connecting plate other side, is provided with arc drift on backing plate one, and arc no-go gage is provided on backing plate two；Institute
It states the sum of the radius of arc drift and the height of bottom plate one and is equal to design arc sections depth tolerances maximum value, the arc no-go gage
The sum of height of radius and bottom plate two is equal to design arc sections depth tolerances minimum value；
The detection method further includes arc sections depth detection step:
Go-no go gauge is adjusted, so that the arc drift in go-no go gauge is below position, the arc no-go gage in go-no go gauge is in top
Position；It is moved downward by go-no go gauge is vertical again, so that arc drift is inserted into the arc sections of fastener heightening base plate under iron base plate,
The side of connecting plate is in contact situation with the level board of fastener heightening base plate under iron base plate in observation go-no go gauge；
Go-no go gauge is adjusted, so that the arc no-go gage in go-no go gauge is below position, the arc drift in go-no go gauge is in top
Position；It is moved downward by go-no go gauge is vertical again, so that arc no-go gage is inserted into the arc sections of fastener heightening base plate under iron base plate,
The other side of connecting plate is in contact situation with the level board of fastener heightening base plate under iron base plate in observation go-no go gauge；
When the insertion of arc drift, observes and fitted closely between the side of connecting plate and level board and when arc no-go gage is inserted into
When, it observes between the other side of connecting plate and level board when there is gap, then determines medial angle qualification；Conversely, then determining
It is unqualified.
