Process and device for the alignment of a road side iron especially a curve track based on a radius of the guide iron

摘要

A mobile track liner comprises a laser beam gun in an uncorrected track section emitting a reference beam forming a chord in the arc of a track curve, and a laser beam receiver mounted on the liner, laser beam gun and receiver are transversely adjustable in relation to fixed points, such as telegraph poles and like markers defining a planned track position and respectively associated with the laser beam gun and the receiver. A control means for the track lining converts lining error signals which are a function of the receiver position in dependence of the length of the path of the movement of the receiver on the track into lining control signals. In the lining method, the receiver on the liner is moved towards the laser beam gun which is mounted on a carriage in the uncorrected track section.
