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.

A method for reprofiling at least one switch blade (11, 12) of a railroad switch (2) laid in a railway track (1) by means of at least a first machining aggregate (35, 35′) held on a machining vehicle (34) and adjustable relative thereto, with a first machining tool (33, 33′), whereby the following steps are performed:
- travelling on the laid rails (5-1, 5-2) of the railway track (1) with the machining vehicle (34) up into the area outside of the railroad switch (2) to be reprofiled,
- spaced arrangement of the switch blade (11, 12) to be reprofiled from the stock rail (9, 10) of the rails (5-1, 5-2) which interacts with the switch blade (11, 12) in transverse direction with respect to a track axis (23) defined by the railway track (1) and thereby formation of a gap (39) extending in the direction of the track axis (23) between the stock rail (9, 10) and the switch blade (11, 12) to be reprofiled,
- conveyance of the machining vehicle (34) with its at least first machining tool (33, 33′) to the switch blade (11, 12) to be reprofiled,
- positioning and conveyance of at least one counterhold (40) held on the machining vehicle (34) within the gap (39) formed between the stock rail (9, 10) and the switch blade (11, 12) to be reprofiled,
- performance of a first machining step of the profiling by reprofiling on the 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
- pressing the switch blade (11, 12) to be reprofiled against the counterhold (40) during profiling by means of at least a first machining tool (33, 33′) and supporting the switch blade (11, 12) to be reprofiled on the counterhold (40) in a transverse direction with respect to the track axis (23).
