Abstract
The invention relates to a mobile device for correction of a vertical position of a pre-measured track, in particular for a track maintenance machine, including a measuring system which comprises a moving chord as reference base, and including a lifting device for lifting the track to a target level prescribed at a work location by means of the moving chord. In this, the moving chord is defined at two reference locations as to its position relative to a non-corrected area of the track, wherein the work location is arranged behind the reference locations in a working direction. In this manner, the position of the moving chord is defined unambiguously and precisely at all times.
Claims11
A mobile device for correction of a vertical position of a pre-measured track having two rails for a track maintenance machine including a front measuring trolley, a rear measuring trolley a lifting unit and a tamping unit, the mobile device comprising:
- a measuring system comprising:
- a moving chord as reference base, and
- a lifting device for lifting the track to a target level prescribed by means of the moving chord at a work location;
- a circuit means which is designed for virtual lifting of the moving chord and/or of a levelling sensor;
- wherein the moving chord is defined at two reference locations comprising a first reference location and a second reference location, as to the moving chord's position relative to a non-corrected region of the track,
- wherein the moving chord is arranged between the first reference location and the work location;
- wherein the first reference location corresponds to the position of the front measuring trolley;
- the second reference location corresponds to the position of the middle measuring trolley;
- and that the work location is arranged behind the reference locations in a working direction—wherein the work location is arranged between the lifting unit and the tamping unit wherein the work location corresponds to the position of the rear measuring trolley.
A method for correction of a track with a mobile device for correction of a vertical position of a pre-measured track having two rails in particular for a track maintenance machine including a front measuring trolley, a rear measuring trolley a lifting unit and a tamping unit, the mobile device comprising:
- a measuring system comprising:
- a moving chord as reference base, and a lifting device for lifting the track to a target level prescribed by means of the moving chord at a work location;
- wherein the moving chord is defined at two reference locations comprising a first reference location and a second reference location, as to the moving chord's position relative to a non-corrected region of the track, wherein the moving chord is arranged between the first reference location and the work location;
- wherein the first reference location corresponds to the position of the front measuring trolley;
- the second reference location corresponds to the position of the middle measuring trolley;
- and that the work location is arranged behind the reference locations in a working direction—wherein the work location is arranged between the lifting unit and the tamping unit wherein the work location corresponds to the position of the rear measuring trolley;
- the method comprising:
- moving the moving chord along the track in the working direction
- lifting the moving chord at the first and second reference locations virtually or by means of levelling devices according to the corresponding target levels,
- lifting the track by means of the lifting unit at the work location in an amount of a lift prescribed by means of the moving chord.
