The track wave mill detection of sectional track detection system 100 uses opposing straight degree comparison in difference method principle, due to
Sectional track detection 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 straightness can not be established, therefore sectional track detection system 100 passes through skate (the first skate
1 to the 4th skate 8) mechanical filter function generate a trolley motion track low frequency wave, thus 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 detection system 100 it is big
Small and waveform is influenced by track wavelength, and shortwave is detected, and the data measured directly of sectional track detection system 100 are
The amplitude measured under chord length L (length of L=track detecting 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 of the first skate 1 and the second skate 5 can be mounted on the first measurement cabinet 3 by bolt
On, each of third skate 11 and the 4th skate 8 can be mounted on the second measurement cabinet 9 by bolt.First skate 1
Horizontal force face it is consistent with the horizontal force face of the second skate 5, the water in the horizontal force face of third skate 11 and the 4th skate 8
Flat acting surface is consistent.

Gas can be equipped in an example of the invention, on crossbeam 601 to support.When the gas on crossbeam 601 is supportted defined
When working under pressure to the first measurement arm and the second measurement arm, due on the first measurement arm and the second measurement arm
Roller 10 acts on rail effect side so that the first skate 1, the second skate 5 and be located on the first measurement cabinet 3 swash
Optical displacement sensor 903 can traveling and measurement on certain position of the top surface of the first track 14, and third is arranged
The 11, the 4th skate 8 of wheel and the laser displacement sensor 903 being located on the second measurement cabinet 9 can be in the top surfaces of the second track 15
Certain position on traveling and measurement.That is, the connection between roller 10 and the first measurement arm and the second measurement arm
It connects that be designed as clearance distance adjustable, that is, realizes and wave mill position measurement is adjusted.
An adjustable clearance distance and locking are designed in the connection place of roller 10 and the first measurement arm and the second measurement arm
Mechanism.Under normal circumstances, roller 10 and the clearance distance of the contact point on the inside of track to laser displacement sensor 903 are 1/
2 rail head is wide, i.e., what laser displacement sensor 903 measured is the wave mill situation of rail top center line.If grinding feelings according to rail level wave
When condition needs to adjust, the adjuster that scale is shown can be stirred, is adjusted within the scope of ± 15mm, required position is measured
Wave grinds situation.
As shown in fig. 6, the first end (such as right end) of crossbeam 601 can pass through the first gas spring 602 and the first measurement case
Body 3 is connected, and the second end (such as left end) of crossbeam 601 can be connected by the second gas spring with the second measurement cabinet 9.Thus may be used
So that the structure of track detecting trolley 120 and sectional track detection system 100 is more reasonable.That is, track detecting is small
Vehicle 120 may include transverse beam assembly 6, and transverse beam assembly 6 may include crossbeam 601, the first gas spring 602 and adjusting spanner 603.
Preferably, the channel for arranging signal cable and light source cable can be equipped in crossbeam 601.Crossbeam 601, first
Cable plug mounting hole can be equipped on each of measurement cabinet 3 and the second measurement cabinet 9.It is possible thereby to examine track
The structure for surveying trolley 120 and sectional track detection system 100 is more reasonable.
The track profile detection of sectional track detection device 110 uses machine vision image recognition measuring technique.It is mobile
The monochromatic line laser rays for being parallel to rail type face that the application laser generator 902 of formula track detection device 110 emits, in-orbit track
Head, web of the rail lower part and rail bottom edge generate the laser rays of high illumination (bright), sketch the contours of the continuous clear, rail of lines on rail type face
Head lower gnathion (breakpoint) determines, the specific contour line in rail bottom edge.Since rail head lower jaw is along endpoint (breakpoint) determination, rail bottom
Edge is clear, therefore gnathion, rail bottom edge can be under the rail head for not wearing away rail and wearing away two kinds of contour lines of rail of standard
Exact matching compares kind of a contour line parameter in this way, can acquire rail head type surface wear data.
In a specific example of the invention, video camera installation position and two there are two being set on the first measurement cabinet 3
A laser generator installation position, the first two video camera installation positions measured on cabinet 3 can be spaced apart along the first direction, the
Two laser generator installation positions on one measurement cabinet 3 can be spaced apart along the first direction.Specifically, the first measurement cabinet
