Abstract
PURPOSE: To detect the cracking of treads of wheels, by attaching detector heads to the tips of arms on both the sides of the platform which can move on guide rails between rails for the wheels and by elastically bringing the detector heads into contact with the wheel treads.
CONSTITUTION: The platform 11 moves on the guide rails 3, 3' between the rails 2, 2' for the wheels 1. Arms 14, 14' are secured to vertical shafts 13, 13' so that the arms are turned by a pulse motor 17 into non-checking position or checking position. When the checked vehicle 5 moves left on the rails 2, 2' this is detected by a photoelectric tube. Then, the arms 14, 14' are moved by the pulse motor into the checking position and guide rollers of the detector heads 22 attached to the tips of the arms are brought into contact with the treads and flanges of the wheels 1 to check whether or not there are cracks on the treads of the wheels while the platform 11 is also moving left.
