Embodiment, broadly falls into the scope of protection of the invention.
As shown in Figure 1: a kind of double track profile measurer, including 2 2D laser sensors 7 and 2 sensings be arrangeding in parallel
Device bearing 3,2D laser sensor 7 is located in sensor enclosure 4, and 2 sensor enclosure 4 are respectively arranged on 2 sensor support base 3 phases
To 2 sides on and 2 sensor enclosure 4 between connected by connecting rod 5；
Connecting rod 5 one end is fixing with a sensor support base 3 to be connected, and the other end is by 2 pneumatic strut 8 and another 1 biography
Sensor bearing 3 connects, and is provided with linear bearing 6 in connecting rod 5, and linear bearing 6 is with this sensor support base 3 by adpting flange 9 even
Connect；
It is respectively equipped with on above-mentioned 2 sides and the working edge roller 2 of tested rail inwall CONTACT WITH FRICTION, working edge roller 2
It is provided with encoder；The lower section of sensor support base 3 is provided with walking and supports skate 1, and 2D laser sensor 7 is provided with network interface.
Operation principle: use import 2D laser sensor on 2 sides that 2 sensor support bases 3 are relative, can be to difference
The Rail Surface of model carries out two-dimensional silhouette scanning, and laser beam is amplified in order to form a static laser by one group of certain lenses
Line, projects by Rail Surface, and optical system the diffusing this laser rays of high-quality projects extremely sensitive 2D
On the photosensitive matrix of laser sensor 7, then calculating the outline position along laser rays by controller, 2D laser sensor 7 is
