Embodiment Construction

[0011] figure 1 A compacting machine 1 , shown only diagrammatically, for compacting a rail 4 formed by rails 2 and sleepers 3 has a machine frame 6 supported on a rail-carrying chassis 5 . The compactor 1 can be moved in a working direction 10 as indicated by the arrow by means of the motor 7 as well as the drive 8 and the driver's cab 9 . A control device 12 located in the working chamber 11 serves to activate and control the individual working units of the compactor 1 . The compacting machine 1 is equipped with a compacting unit 13 connected to the machine frame 6, which can be adjusted vertically and laterally by means of a drive 14 and is designed for compacting the track 4 - and, in the process, in particular for a switch Operation within 15. Between the rail-carried undercarriages 5, arranged immediately in front of the compacting unit 13 with respect to the working direction 10, is a rail lifting unit 17, which can be adjusted vertically and laterally via a drive 16 ...

Abstract

A tamping machine for tamping under a track is equipped with a track lifting appliance, which is positioned immediately in front of a tamping appliance, and an additional lifting device (19) - which is designed to lift a branch rail section (20), which branches off from the main track, of a switch. This is attached to a support (21), which runs at right angles to a machine longitudinal direction, and has a lifting tool (27) which can be placed on a rail head (26). Two running-on rollers (32), which are separated from one another in the machine longitudinal direction, can rotate on a common rotation plane (33) and are in the form of disks, for resting on a first flank (34) of the rail head (26) are connected to the additional lifting device (19). A flange roller (36) is provided for resting on a second flank (35) of the rail head (26) and for the additional lifting device (19) to rest thereon. The additional lifting device (19) can be pivoted by means of a drive (41) about an axis (42) relative to the support (21).

Description

technical field [0001] The invention relates to a compacting machine for compacting rails according to the preamble of claim 1 . Background technique [0002] A compacting machine of this type is known, for example, from EP-A 1 143 069, which is suitable not only for the compaction of so-called normal straight rail sections, but also especially for compaction in the area of ​​branch roads. During this time—parallel to the lifting of the main rail by means of the rail lifting unit arranged next to the compacting unit—the branch rail lines are also simultaneously lifted by means of auxiliary lifting devices rolling on the branch rail lines via rollers with two flanges. For this purpose, the auxiliary lifting device consists of a lifting tool connected to the beam and adjustable by means of a drive in the transverse and vertical direction of the track, said lifting tool can be applied to the rail head of the branch railway, and when the compactor is continuously advanced in the...
