FIELD: railway transport; testing facilities. ^ SUBSTANCE: invention can be used for checking wear of rails on railways and streetcar tracks. Device for testing wear of rails includes pulse generator and recorder and second pulse generator. First and second pulse generators are made in form of electronic transducers furnished with spring-loaded rods with rack gears engaging with surfaces of rail and with gears on axles of which light breakers are installed, and with light emitting diodes connected by wires with photorelays. Recorder is made up of radio electronic elements, supply unit and control panel with push buttons and change-over switches. Pulse generators and recorder are connected by wires. First pulse generator is installed on base on edges of which bellcranks are mounted for rotation on joints. Position lock of bellcranks is installed between upper parts of bellcranks furnished with handles, position lock being made of concave parts and screw. Second pulse generator is installed lower than the base on one of bellcranks. Stops with slots and fastening screws are made in lower parts of bellcrank to secured their position relative to bellcranks. ^ EFFECT: improved safety, reduced possibility of breakdown in operation of rolling stock on railways and streetcar tracks. ^ 5 cl, 7 dwg |
