The assembling of fastener system contacting piece, damping property, insulation performance, location of rail adjustment capability, buckle press, play journey and rail is indulged
Different technical indicators is all defined to resistance etc., it is one of important indicator to withhold force value.
For " e " type spring, the country has related buckle press measuring instrument and Patents documents to disclose." e " type spring is buckled
The formation of pressure relies primarily on the deformation of its own, and design parameter with itself, material are related with process and heat treatment technique,
Its contact with rail only has a small contact surface, is lifted up by the fixture force of special designing, can measure buckle press.
For " ω " type spring, the shape on the ramp at rail flange of rail angle must be withheld by fastening bolt or nut
Into buckle press.The size of buckle press depends on tightening torque when fastening bolt or nut." ω " type spring withholds connecing for rail
Contact should be two, and wherein limb front end should just be contacted with rail by code requirement or have the gap no more than 0.5mm, at this time
Buckle press be considered to reach design specification requirement.If middle limb front end is in close contact with rail, buckle press at this time can be more than
It is required that withhold force value；If gap is excessive between middle limb front end and rail, buckle press at this time can be less than desired buckle press
Value.For a long time, since " ω " type elastic-strip pressure value does not have suitable measurement means, it is contemplated that operability, buckle press are big
Small is usually to be scaled the torque value of fastening elastic bar fastener bolt/nut to control.
In order to detect that spring withholds the buckle press of rail, one of the method for science is to use " power transfer method ".I.e.：Spring
Withhold on rail, the buckle press of spring acts on rail completely, when the fixture of special designing clamps spring and hangs down along rail
Line direction just lifts spring completely upwards when withholding end, its buckle press to rail effect will be transferred completely on fixture, be examined
The power measured at this time is buckle press.
And this first relates to detection device can be conveniently fixed in locating scheme and the detection at rail head of rail position online
The measurement rack conceptual design of device.For convenience of on-line checking, using portable scheme, when detection, can facilitate in rail head of rail portion
Position is fixed and removes and answers accurate positioning, and to consider new relayable rail difference, adapts to the spring of different model, also should ensure that
Measuring surface is vertical with rail perpendicular bisector.In order to ensure it is to be measured measure one's own ability vertical with rail surface, detection device should can be horizontal along rail
Adjust automatically.
