Abstract: In a rail detection system, a traveling mechanism and a horizontal moving mechanism move a detection device accurately to a position directly above a position to be detected by moving parallel to an extension direction of the rail. A vertical lifting mechanism is provided with the detection device, and can drive the detection device to lift up and down. A aligning mechanism is connected with the detection device, and includes a force-bearing mechanism and a follow-up mechanism. The force-bearing mechanism is configured to generate a force along a direction perpendicular to the extension direction of the rail when being in a non-aligned position. Under the condition of being forced, the follow-up mechanism makes an adaptive adjustment movement along the direction perpendicular to the extension direction of the rail so that the detection device is aligned with a center of the rail.
