The position of two measurement babinets 9 is constant, and video camera 901 is constant with respect to the position of the first track 14 and the second track 15, the figure of shooting
Image position is constant.Laser displacement sensor 903 is also constant with respect to the position of the first track 14 and the second track 15, measures position not
Become.
When twist irregularity occurs in track, can be rotated because the first measurement babinet 3 and second measures babinet 9 around crossbeam 601, i.e.,
The first skate 1 and the second skate 5 that are located on the first measurement babinet 3 and the third skate 11 being located on the second measurement babinet 9
Be not in rising phenomenon with the 4th skate 8, the position of 903 relative orbit of video camera 901 and laser displacement sensor will not produce
Changing, the image of shooting and the position of measurement displacement do not generate variation yet.This way it is ensured that sectional track detection device
110 measurement accuracy, while it is more smooth to carry out trolley.
Preferably, the first measurement babinet 3 and second, which measures babinet 9, to be rotated around crossbeam 601.It is possible thereby to examine track
Self-control can preferably be carried out according to the geometry state of current orbit by surveying trolley 120, be located at so as to be further ensured that
The measurement accuracy of sectional track detection device 110 on track detecting trolley 120, while make pushing away for track detecting trolley 120
Row is more smooth.

The track wave mill detection of sectional track detecting system 100 uses opposing straight degree comparison in difference method principle, due to
Sectional track detecting system 100 can be carried out continuously the detection of track profile and the mill detection of track wave on the move, measure operation
The absolute coordinate system of description track glacing flatness can not be established, therefore sectional track detecting system 100 passes through skate (the first skate
1 to the 4th skate 8) mechanical filter function generate the low frequency wave of a trolley motion track, so as to using this low frequency wave as base
Standard measures the amplitude difference relative to high frequency waves.According to this principle, the detection data of sectional track detecting system 100 it is big
Small and waveform is influenced by track wavelength, and shortwave is detected, and 100 data measured directly of sectional track detecting system are
The amplitude measured under chord length L (length of L=track detectings trolley 120), this numerical value have certain precision, to railway maintenance and
Detection has certain directive significance.
That is, because having certain mathematical relationship between detected value and actual value, according to the different analysis inspections of wavelength
Functional relation between measured value and actual value realizes the detection of track wave mill.
Preferably, each in the first skate 1 and the second skate 5 can be mounted on first by bolt and measure babinet 3
On, each in 11 and the 4th skate 8 of third skate can be mounted on by bolt on the second measurement babinet 9.First skate 1

It surveys component to work at the same time, not interfere with each other, realize and measured while track profile is ground with track wave, the dynamic moved towards along track is continuous
It measures (uninterrupted detection).In other words, sectional track detection device 110 can realize that track profile and track wave mill double track are same
When, the continuous detection of dynamic, in order to facilitate the transport of field personnel, sectional track detection device 110 can be designed as can
Detachable.
The present invention also provides track detecting trolley 120, it is small that sectional track detection device 110 may be mounted at track detecting
On vehicle 120.Detection efficiency is which thereby enhanced, changes the conventional rails wave mill fixed limitation of detection device test position, realizes rail
Road wave mill test position is adjusted.Track detecting trolley 120 is designed as hard and soft structure, measurement accuracy is ensure that, makes simultaneously
Trolley implementation is more smooth, and measuring instrument adapts to field work demand, and environment temperature allowed band is big, and not by bad weather shadow
It rings.
