A Fault Detection Device for Portable Track Circuit

The utility model discloses a portable track circuit fault detection device, comprising a support ring. The center of the support ring is hollowed out to form an annular cavity. A cupped intermediate cylinder is installed perpendicular to the annular cavity in the annular cavity. Multiple loops are passed between the intermediate cylinder and the support ring. The connecting column is connected and fixed; Two rolling rings are respectively arranged on both sides of the outer circular surface of the support ring, and a rail support cavity is formed between the two rolling rings. The balls are installed in the area of the gap formed between the inner circular surface and the outer circular surface of the support ring; the telescopic handle is used for manual operation, and is inserted into the hollow intermediate cylinder when not in use. The utility model is used for fault detection in track circuits. It is convenient to store when not in use, has a small total volume, is more convenient to carry, and can save labor and reduce fatigue during detection.
