Abstract
A method for reprofiling a switch blade of a railroad switch laid in a railway track uses at least a first machining aggregate with a machining tool held on a machining vehicle. For the purpose of reprofiling, the switch blade to be reprofiled is arranged at a distance to a stock rail interacting therewith in a transverse direction, thereby forming a gap. A counterhold held on the machining vehicle is positioned in the gap, wherein during profiling the machining vehicle is guided along the switch blade and the latter is pressed onto the counterhold by the machining tool and supported there.
Claims16
A method for reprofiling at least one switch blade (11, 12) of a railroad switch (2) laid in a railway track (1), the reprofiling being carried out by means of at least a first machining aggregate (35, 35′) held on a machining vehicle (34), the at least first machining aggregate being adjustable relative to the machining vehicle, the at least first machining aggregate comprising a first machining tool (33, 33′), the method comprising the following steps:
- travelling on laid rails (5-1, 5-2) of the railway track (1) with the machining vehicle (34) up into an area outside of the railroad switch (2) to be reprofiled,
- arranging the at least one switch blade (11, 12) to be reprofiled so as to be spaced from a stock rail (9, 10) of the laid rails (5-1, 5-2) in a transverse direction with respect to a central longitudinal track axis (23) of the railway track (1) so as to form a gap (39) extending in the direction of the track axis (23) between the stock rail (9, 10) and the at least one switch blade (11, 12) to be reprofiled,
- conveyance of the machining vehicle (34) with its first machining tool (33, 33′) to the at least one switch blade (11, 12) to be reprofiled,
- positioning and conveyance of at least one counterhold (40) held on the machining vehicle (34) to a location within the gap (39) formed between the stock rail (9, 10) and the at least one switch blade (11, 12) to be reprofiled,
- performance of a first machining step of the profiling by reprofiling on the at least one switch blade (11, 12) to be reprofiled whereby the at least first machining aggregate (35, 35′) with its first machining tool (33, 33′) is guided along the switch blade (11, 12) to be reprofiled, and
- during the profiling by means of at least the first machining tool (33, 33′), pressing the at least one switch blade (11, 12) to be reprofiled against the at least one counterhold (40) that is located in the gap (39) and supporting the at least one switch blade (11, 12) to be reprofiled on the at least one counterhold (40) in a transverse direction with respect to the track axis (23).
