DEVICE FOR MAGNETIC POWDER TESTING OF LOCOMOTIVE WHEEL TREADS Russian patent published in 2023 - IPC G01M17/10 B61K9/12 G01N27/84 

FIELD: non-destructive testing.

SUBSTANCE: invention is intended for magnetic particle testing of wheel treads in locomotive depots. A device for magnetic particle testing of a locomotive wheel tread comprises a frame, a saddle-shaped solenoid that can be installed in a working position above the internal turned surface of the controlled tread, vertically oriented in the plane of its rotation, drives and a control unit. The device for magnetic particle testing of the locomotive wheel treads also comprises support driving and driven rollers mounted on the frame adapted for installing a controlled tread on them with its outer surface and equipped with guides fixed on the frame adapted of covering the side faces of the tested tread with pressure rollers mounted on the free ends of the guides. The saddle solenoid is supplemented with a manipulator made in the form of an arcuate lever hinged on the frame and equipped with a rotation drive made in the form of a pneumatic cylinder, the body and rod of which are pivotally connected to the frame and said lever, respectively, and its end part is connected by means of a bracket to the body of the saddle solenoid configured for moving the latter in a vertical plane passing through the centre across the tested tread.

EFFECT: manufacturability of the tread testing process improves, and the labour safety of the maintenance personnel increases.
