APPARATUS CAPABLE OF TRAVELING FOR MILLING RAIL HEAD AND METHOD FOR REPLACING TIPPED TOOL WITH THE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an apparatus capable of traveling for milling a rail head of a railroad track rail arranged in the ballast, the apparatus that has a rotationally driven milling-cutter head pivotally supported by a vehicle body for supporting a milling cutter head drive unit and has at least one cutter gear comprising multiple tipped tools for milling the rail head in this milling-cutter head.SOLUTION: A milling cutter head 5 has a disk-shaped tool support 14 circumferentially disposed of a cassette 16 including the tipped tools. The cassette is disposed to multiple support segments 15 connected to the tool support 14 in a removable manner. The tool support 14 is defined as being connected with a milling-cutter head drive unit 7, disposing at least two different cassettes 16 with respect to one or more of the number of cutter gears, a mutual interval of the cutter gears, a rake angle of each tipped tool and a setting angle of each tipped tool circumferentially including the tipped tools, or both of the above.
