Abstract
A machine (1) for picking up and storing rail fastenings (2) of a track (3) includes two rail fastening pickup devices (9). Arranged between these and a rear on-track undercarriage (4)—with regard to a working direction (6)—is a crawler track (24). At each longitudinal side of the machine, two devices (29) for guiding rails (30) are provided which are adjustable by drives (28) relative to the machine frame (5) and arranged one following the other in the longitudinal direction of the machine.
Claims8
A machine for picking up and storing rail fastenings (2) of a track (3), including a vertically adjustable crawler track (24) arranged between two on-track undercarriages (4) on a machine frame (5) and a rail fastening pickup device (9), wherein:
- a) the rail fastening pickup device (9) consists of two conveyor belts (10), each having a rotatable magnetic drum (12) at a lower deflection end (11) and a discharge end (14), formed by an upper deflection end (13), which is positioned above the machine frame (5),
- b) the crawler track (24) is arranged between the rail fastening pickup device (9) and the rear on-track undercarriage (4) with regard to a working direction (6),
- c) between the lower deflection end (11) of the rail fastening pickup device (9) and the front on-track undercarriage (4), at least two devices (29) for guiding rails (30) are provided per longitudinal side of the machine, the devices (29) being adjustable by drives (28) relative to the machine frame (5) and arranged one following the other in the longitudinal direction of the machine.
A method of renewing a track (3), wherein rails (30) and sleepers (38) are renewed in the course of continuous working advance and, prior to the removal of the old rails (30), rail fastenings (2) are detached from the sleepers (38) and collected in a container, wherein prior to the removal of the rail fastenings (2), the old rails (30) are lifted from the sleepers (38), and wherein, after the removal of the rail fastenings (2), the new rails (30) are laid provisionally upon the old sleepers (38) and lifted again for exchanging the sleepers (38).
A method of renewing a track (3), wherein rails (30) and sleepers (38) are renewed in the course of continuous working advance and, prior to the removal of the old rails (30), rail fastenings (2) are detached from the sleepers (38) and collected, wherein prior to the removal of the rail fastenings (2), the old rails (30) are lifted from the sleepers (38), and wherein, parallel thereto, the new rails (30) are lifted from the track (3) and, after the insertion of the new sleepers (38), are laid upon the same.
