Turnout rail bottom eddy current detection probe

The utility model discloses a turnout rail bottom eddy current detection probe which comprises a detection head, a movable connecting component, a probe rod and a handle, one end of the probe rod is movably connected with the detection head through the movable connecting component, and the other end of the probe rod is fixedly connected with the handle. The detection head is provided with a detection surface or two detection surfaces which are symmetrically arranged up and down, and array eddy current detection sensors are arranged on the detection surfaces. Due to the design of the movable connecting component, flaw detection personnel can ensure that the detection head is attached to the surface of the rail bottom and cannot tilt up only by exerting upward lifting force on the hand during working, and the lifting-off situation is reduced. Furthermore, a strip magnet is additionally arranged on the probe detection surface, so that the probe detection surface can be always attached to the surface of the botto
