[0018] FIG. 1 shows a side view of two tamping assembly groups arranged on a track-tamping machine,

[0019] FIG. 2 shows a view of the right side of a tamping assembly group arranged on a track-tamping machine, and

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] The track-tamping machine 100 for compressing the ballast bed of a track comprises at least two tamping assembly groups V, H, each having at least two tamping assemblies ST for tamping the track per track-tamping machine side R, L, which can be displaced transversely to the track-tamping machine longitudinal direction AR by means of a transverse-movement device and are arranged in a row, of which the respective outer tamping assembly can be displaced in a console with guides assigned to it by means of an adjusting drive 21 transversely to the track-tamping machine longitudinal direction AR. The inner tamping assembly can be displaced on the same guides and in the same console 3 independently of the outer tamping assembly with an adjusting drive transversely to the track-tamping machine longitudinal direction AR as far as the outer tamping assembly ST. The tamping assembly groups V, H are jointly mounted on a carrier 18 so as to be rotatable about a track-tamping machine vertical axis A for the purpose of rotary adjustment.

[0022] The at least two tamping assembly groups V, H are arranged one behind the other in the track-tamping machine longitudinal direction AR and are rotatably mounted about the track-tamping machine vertical axis by means of a common rotational device 2. In addition, the individual tamping assemblies of the tamping assembly groups can be displaced independently of one another transversely to the track-tamping machine longitudinal direction AR and can be raised and lowered independently of one another with respect to the console 3.

[0023] In addition, the tamping assembly groups V, H can be displaced between track-tamping machine undercarriages by means of an actuator in the longitudinal direction of the track-tamping machine within a provided displacement range between the track-tamping machine undercarriages.

[0024] At least two guides 6, 20 per pair of tamping assemblies LHA with LHI, RHA with RHI, LVA with LVI, RVA with RVI and per track-tamping machine side are mounted in the console 2, which guides 6, 20 are offset from one another in the longitudinal direction of the track-tamping machine and in the direction of a track-tamping machine vertical axis. The tamping assemblies ST are equipped with tines 11 that can be pivoted about a longitudinal axis of the track-tamping machine for tamping switches.

[0025] FIG. 1 shows the arrangement of two tamping assembly groups H (rear) and V (front) arranged one behind the other in the longitudinal direction of the track-tamping machine AR, with tamping assemblies I (inside) and A (outside) from the side in the longitudinal direction of the track. FIG. 2 shows a schematic view in the longitudinal direction of the track-tamping machine AR, with only the right-hand two tamping assemblies I, A of the rear tamping assembly group H shown.

[0026] Cross beams 18 are attached to a frame of a satellite 1 and support a slewing ring of the rotational device 2. The rotational device is connected to the console 3 for the columns of the guides 6, 20. The guides 20 of a pair of tamping assemblies, e.g. a rear one, consisting of the rear inner tamping assembly H, I and the rear outer tamping assembly H, A, are connected to unit frames 4, 9 of the outer tamping assembly in the region 7. The respective inner tamping assembly HI, VI can be moved on these guides 20. Drives 21 allow the tamping assemblies to be displaced transversely independently of each other in the longitudinal direction of the track. The guides 20 are arranged in such a way that two of them are opposite each other. To make full use of the available space, recesses 6 are provided in each of the unit frames 4, 5 into which the guides of the assembly pair L or R on the other side can slide freely.

[0027] The tamping assemblies consist of tamping arms 10 in which tamping tines 11 are fastened. The tamping arms 10 are mounted on the tamping box 15 so that they can rotate about an axis 16. The tamping drives 14 engage at the other end of the tamping arms. The tamping drives 14 have one or more engagement points 17 in the tamping box 15. The tamping drives can be designed as a pure linear drive or as an eccentric shaft drive with auxiliary cylinders. For reasons of clarity, the tamping assemblies with laterally pivoting tines 11 are not shown. The tamping boxes move up and down on vertical guides 13 mounted in the tamping box frame 9. This allows the tamping assemblies to be raised and lowered individually and independently of each other with respect to the console 3. The tamping assemblies can be lowered and raised independently of one another via drives 8. Two sleepers 12 are shown which can be processed in one operation. A drive unit mounted on the slewing ring 2 can be used to adjust the entire tamping arrangement to oblique long sleepers in parallel.
