| 摘要 |
The invention relates to a device for reprofiling the head of at least one rail of a railway track. It comprises a support carrying at least one grinding unit, this support being constituted by the framing of a railroad vehicle provided at one of its ends with at least two wheels resting each on one rail of the railroad track and hinged around at least one axis parallel to the longitudinal axis of the track at its other end onto a rigid frame provided with at least two wheels. The framing is guided by the track and defines at any moment a reference plan for the grinding. Each grinding unit comprises a casing connected to the framing by a device to displace in height and in translation the axis of pivotement of this grinding unit. Each grinding wheel is connected to the casing through a turning table on the one hand, and on the other hand by a device for displacing the grinding wheel. |
