TRACK MAINTENANCE WAGON FOR PICKING UP AND/OR LAYING TRACK PANELS

Abstract

A track maintenance wagon (1) for picking up and/or laying a track panel (10), comprising a wagon frame (2) supported on on-track undercarriages (4), wherein two longitudinal beams (7) of the wagon frame (2) delimit a free opening and are transversely displaceable relative to one another, so that the free opening is changeable as to its width and, in a working position, has greater opening dimensions as a horizontal projection of the track panel (19), and wherein crane rails (8) are arranged on the longitudinal beams (7) for a gantry crane (11) mobile in the longitudinal direction (3) of the wagon. In this, buffers (13) are arranged at two free ends (12) of the longitudinal beams (7).

Claims

5. The track maintenance wagon (1) according to claim 1, wherein a displacement drive (18) for a transverse displacement device (19) is configured electrically.

6. The track maintenance wagon (1) according to claim 4, wherein the displacement drive (18) is configured as a spindle drive.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The invention will be described by way of example below with reference to the attached figures. There is shown in schematic representation in:

[0015] FIG. 1 a side view of track maintenance wagon with a gantry crane,

[0016] FIG. 2 top view of track maintenance wagon in transport position, and

[0017] FIG. 3 top view of track maintenance wagon in working position

DESCRIPTION OF THE EMBODIMENTS

[0018] A track maintenance wagon 1 visible in FIG. 1 has a beam-shaped wagon frame 2 which extends in a longitudinal direction 3 of the wagon and is supported at the ends on on-track undercarriages 4 and mobile by means of the same on a track 5. The wagon frame 2 has, on its longitudinal beams 7 which are displaceable in transverse direction 6 of the track, crane rails 8 for mobility of a gantry crane 11 equipped with gripping devices 9 for grasping track panels 10. Buffers 13 are arranged at the ends 12 of the longitudinal beams 7 which are free at both sides.

[0019] In FIG. 2, the track maintenance wagon 1 is shown in a transport position during transfer travel. To that end, the longitudinal beams 7 are displaced on transverse beams 14 in the direction towards a track center 15. The transverse beams 14, arranged transversely to the longitudinal beams 7, are arranged for rotation about a vertical axis 16 on the on-track undercarriages 4 designed as bogies 17. Arranged on the transverse beams 14 are transverse displacement devices 19 equipped with displacement drives 18 and guides. By means of the transverse displacement devices 19, the longitudinal beams 7 are transversely adjustable relative to each other.

[0020] Visible in FIG. 3 is a working position of the track maintenance wagon 1. In this position, the longitudinal beams 7 are displaced by means of the transverse displacement devices 19 in the direction towards a respective stop 20 of the transverse beams 14.

[0021] In a simple embodiment shown in FIGS. 2 and 3, draw hooks 21 are arranged centrally on the transverse beams 14.

[0022] Alternatively, in a variant of embodiment shown in dashed lines, pulling devices 22 are located next to the buffers 13 at the ends of the longitudinal beams 7, wherein a length compensation is to be provided for travel in curves. Such pulling devices 22 can be designed in combined structure as rail bridges 23 for connection of the crane rails in the train formation.
