description The utility model relates to an eddy current flaw detector for railways, which comprises a main machine frame 8 which is arranged along the conveying direction of a detected railway. The output and the input ends of the railway of the main machine frame are provided with positioning guide wheel groups 6, 2; a rotary probe frame 3 and sector probe frames 4 are positioned between the positioning guide wheel groups 6, 2 of the output and the input ends. The side face of the railway 1 is also provided with a protective guide wheel 7. The positioning guide wheel groups 2, 6 are respectively a portal type frame 14 and a bounce cylinder 11 for mounting guide wheels. The rotary probe frame 3 is positioned by a guide post 28; an upper and a lower sector probes 34 are simultaneously driven by a cylinder 37. The device can be positioned at the parts of railway detection lines, railway welding lines to replace manual visual inspection. The utility model has the advantages of high accuracy, lightened labor intensity and enhanced efficiency.
