Fig. 2 is that the track clearance detecting sensor is arranged scheme drawing.
The specific embodiment
Fig. 1 is the track clearance scheme drawing, and is as shown in Figure 1, and track clearance described in the utility model is meant the outline line that various device must not be invaded on the circuit outside the vehicle wheel profile.Through the obstacle outline line that lidar measurement goes out, whether the superelevation value that track cross level superelevation device records is in the segment of curve standard, applies mechanically different gauge standard forms, according to the curvature detecting device template is out of shape simultaneously, and judging transfinites a little.The point coordinate that transfinites converts the circuit absolute coordinates into through car body compensation and speed location again;
Fig. 2 is that the track clearance detecting sensor is arranged scheme drawing; As shown in Figure 2; The said track clearance detecting device of the utility model uses two groups of laser radars, track cross level superelevation detecting device and speed registration device, wherein; Laser radar is installed in headstock or the symmetrical position of the tailstock, and horizontal superelevation detecting device of railroad track and track curvature detecting device are installed in car body below centermost.
The track clearance detecting device of a kind of railway clearance detection of dynamic that the utility model provides calculates the cooresponding track clearance parameter of current kilometer post, reaches the purpose that real-time online detects track clearance.This track clearance detecting device has intellectuality, is prone to installation, highly versatile, and the characteristic stable, that antijamming capability is strong.
Above-mentioned preferred embodiment and the institute's application technology principle that is merely the utility model; Any technical personnel of being familiar with the present technique field is in the technical scope that the utility model discloses; The variation that can expect easily or replacement, all should be encompassed in the utility model protection domain in.
