Laser displacement sensor, be arranged in parallel on module slide unit guide rail and for laser displacement sensor horizontal movement displacement into
The grating scale that row counts is arranged in After-Body and the laser range sensor that measures for distance between backs of wheel flanges, and setting exists
The locating rod that underpart and wheel rim vertex for take turns pair are positioned, setting is in underpart and is used for body
It is fixed on the electromagnet of the wheel inner surface of measured wheel pair, and the power supply for being arranged in body and powering for measuring instrument.
Preferably, the power supply is lithium battery.
Further, it is provided with handle on the body.
Compared with prior art, the utility model has the advantages that：
The utility model realizes survey accurate to the two dimension of wheel tread by installing laser displacement sensor and rail plate
Amount, obtains the segmented curved profile of tread configuration, and the accurate measurement to distance between backs of wheel flanges is realized by laser distance sensor,
Being accurately positioned on wheel is realized by electromagnet and positioning column and is fixed.It is former that the utility model is based on laser triangulation
Reason realizes the parameters such as wheel tread shape, flange thickness, flange height, qR values, wheel wear amount, wheel footpath, distance between backs of wheel flanges
Contactless high-precision measures, the measurement accuracy of tread profile and characteristic parameter within ± 0.05mm, inside away from measurement accuracy
Within ± 0.5mm, the time of measuring of single wheel is less than 20s, has highly application value.

Specific implementation mode
The utility model is described in further detail with embodiment for explanation below in conjunction with the accompanying drawings, and the mode of the utility model includes
But it is not limited only to following embodiment.
Embodiment：
As shown in Figures 1 to 3, a kind of high-accuracy portable railway vehicle wheel is to gauging instrument, including body 1, body 1
As shown in the explosive view of Fig. 2 the module slide unit guide rail 2 in 1 front of body is arranged, with module slide unit in conventional structure, concrete structure
Guide rail 2 is coaxially connected and drives the motor driver 3 of the slide unit horizontal movement of module slide unit guide rail 2, is fixed on module slide unit and leads
On the slide unit of rail 2 and moved with the horizontal movement of slide unit and be used to obtain wheel tread shape characteristic parameter laser
Displacement sensor 4 is arranged in parallel on module slide unit guide rail 2 and for being carried out to 4 horizontal movement displacement of laser displacement sensor
The grating scale 5 of measurement is arranged at 1 rear portion of body and for the laser range sensor 6 of distance between backs of wheel flanges measurement, is arranged in machine
The locating rod 7 that 1 lower part of body and 13 wheel rim vertex of wheel for take turns pair are positioned, setting is in 1 lower part of body and for general
Body 1 is fixed on the electromagnet 8 of 13 inner surface of wheel of measured wheel pair, and setting in body 1 and is each use of measuring instrument
The power supply 9 of electrical components power supply, power supply 9 are lithium battery, and the consuming parts connection power supply of lithium battery and measuring instrument is routine techniques, therefore
It repeats no more.It is provided with handle 10 on body 1, conveniently takes.
As shown in figure 4, also needing to cooperation wheel footpath auxiliary device 11 when carrying out wheel footpath measurement using the utility model, measure
In the process, first the wheel footpath auxiliary device 11 is bonded with tested wheel inner surface, the auxiliary at 11 both ends of wheel footpath auxiliary device is determined
The position that position bar is attached to any circumference direction wheel rim peak is positioned, meanwhile, the center of wheel footpath auxiliary device 11 has
