RAILWAY TRACK BUILDING MACHINE IN PARTICULAR FOR CORRECTING TRACK POSITION AND METHOD OF DETERMINING TRACK POSITION ERRORS

摘要

A railroad maintenance machine for correcting the position of the track has a machine frame (7), which is supported on rail running gear and equipped with lining drives (13) for lateral correction of the track position, and measuring carriages (recording cars) (24-26) capable of rolling on a track. These measuring carriages form, together with the machine frame (7) serving as reference basis and also with measurement transducers (32,33,34), a reference system (30) for detection of the actual track position. The measuring carriages (24,26), situated at the front and at the rear end of the reference system (30) in relation to the working direction, are assigned respective banking measurement devices (37,38). In addition, a pressure transducer (39) for detection of the lining forces of the lining drives (13) is provided. IMAGE
