FIELD: calibration equipment.
SUBSTANCE: invention relates to the calibration of a rail track measuring device. Rail track measuring device (3, 28) comprises at least one track measurement car (4) aligned with the lifting and straightening device, and track measuring sensors for measuring position (17) in height, direction (11) and elevation (25) of the rails of rail track (3, 28), and machine frame (13) as the reference zero line (15, 22). In this case, track measurement car (4) is equipped with device (9) for lifting and lowering the track measurement car. For calibration, calibration device (2) aligned with the machine frame is provided. In this case, to calibrate the track measuring sensors, track measurement car (4) is first lowered from the elevated off-rail parking position to the rail track or to an intermediate position. After this, calibrating stops (5) are moved from the rest position to the calibration position using the servo drive, to which track measurement car (4) is subsequently raised and attached. After that, the obtained values of the track measuring sensors are read and entered as a calibration value into the measuring plant and stored. After this, track measurement car (4) is lowered onto the rail track, and then calibration stops (5), if necessary, are moved by the servo drive from their calibration position to their rest position.
EFFECT: as a result, a simple and quick calibration is provided.
