Abstract
A kind of orbit measurement directive wheel, including wheel stand, guide wheel pressing plate, nut, spring shaft, spring, directive wheel connecting rod, idler wheel, bearing, circlip for shaft, circlip for hole, idler wheel axle sleeve, encoder, grating measuring apparatus, small washer composition.There is perforate on guide wheel pressing plate, by two holes through on spring shaft.The other end of spring is directive wheel connecting rod, and the part of directive wheel connecting rod is through spring inner, and another part is through in the hole of wheel stand.The directive wheel connecting rod other end is connected to guide wheel shaft and puts on, and guide wheel shaft is put on secondary fixing bearing, circlip for hole, idler wheel, encoder.One end of grating measuring apparatus is fixed on wheel stand, and floating end is put on fixed to roller shaft.Directive wheel is installed on orbit measurement vehicle, and when measurement vehicle straight rail road moves, idler wheel drives encoder rotation, and so as to draw the distance of straight rail movement, the floating end of grating measuring apparatus generates amount of movement under the drive of idler wheel axle sleeve, so as to measure the well-behaved situation of change of track.
Description
Technical field
The present invention relates to a kind of automobile-used directive wheel of orbit measurement, which is installed on orbit measurement vehicle, can survey automatically
Measure the parameters such as mileage and the gauge of track.
Technical background
The detection of rail circuit, such as in the regular maintenance and maintenance of rail, traditional method is mainly with range estimation and one
As measurer be combined, carry out manual measurement, this method is arduously time-consuming, and measure precision it is not high, it is impossible to meet railway
The requirement of speed-raising development.And in the construction of rail circuit, it is mainly measured with dedicated large-scale track detection vehicle, this side
Method fast power-saving, precision is higher, but use cost is larger, is less suitable for frequent measurement during upkeep operation.So as to develop one
The operational maintenance of quick, reliable, using simplicity, economy the measuring apparatus progress rail circuit of kind measures tool when being laid with
There is important meaning.
The content of the invention
Problem to be solved by this invention be provided when carrying out the operational maintenance of rail circuit or being laid with it is a kind of quick,
Reliably, measuring apparatus conveniently, economic, to detect the various parameters of track.The present invention employs collection to realize above-mentioned function
Into designing scheme is changed, measuring mechanism and measuring instrument are become one, are easily installed in various orbit measurement vehicles.Present invention bag
Include wheel stand, guide wheel pressing plate, nut, spring shaft, spring, directive wheel connecting rod, idler wheel, bearing, circlip for shaft, hole elasticity
Baffle ring, idler wheel axle sleeve, encoder, grating measuring apparatus, small washer composition.Wheel stand plays fixation, by all the zero of directive wheel
Part is fixed on measurement vehicle frame, and spring shaft is fixed through the hole on wheel stand with nut.There is perforate on guide wheel pressing plate, pass through two
A hole is through on spring shaft.Spring is also through on spring shaft simultaneously.The other end of spring is directive wheel connecting rod, directive wheel connecting rod
A part is through spring inner, and another part is through in the hole of wheel stand.Card has circlip for shaft on directive wheel connecting rod, to support
Firmly spring end.The directive wheel connecting rod other end is connected to guide wheel shaft and puts on, and guide wheel shaft is put on secondary fixing bearing, hole bullet
Property baffle ring, idler wheel, encoder.One end of grating measuring apparatus is fixed on wheel stand, and floating end is put on fixed to roller shaft.It selects
Rotary encoder and grating measuring apparatus be the height that rotation angle and displacement are demarcated with digital pulse signal, and by using
Frequency multiplier circuit, measurement accuracy can reach more than 5um, and reliability samples 6 groups of data compared with high measurement every time, can by calculating
It is turned to, the core parameters such as gauge, by microcontroller real-time sampling and arranges data, upper industry control is uploaded to by CAM buses
Computer carries out data operation, and shows result of calculation.
Specific work process：
Directive wheel is installed on orbit measurement vehicle, and idler wheel top to track inside edge under the pretightning force effect of spring is surveyed
When measuring the movement of vehicle straight rail road, idler wheel drives encoder rotation, so as to draw the distance of straight rail movement, while when both sides track gauge
When changing, the floating end of grating measuring apparatus generates amount of movement under the drive of idler wheel axle sleeve, so as to which the rule for measuring track becomes
Change situation.Measurement directive wheel finally obtain track gauge year track length situation of change.
