Embodiment Construction

[0013] Figure 1a The shown machine 1 has an upwardly recessed machine frame 2 which is displaceable by means of an on-rail chassis 3 on a rail 6 in a working travel 5 in a working direction 4 . An excavating device 7 consisting essentially of a rotatable conveyor chain 8 connected end to end is arranged between the running gear 3 on the track. In this example, a conveyor chain 8 is guided under the track 6 during working operation and is used to collect chunks 9 from the track bed 10 . In the region of the upper conveyor chain offset 11 of the excavating device 7 is arranged a discharge device 12 for discharging the collected lump material 9 transported away via the conveyor device 27 .

[0014] figure 2 and image 3 As can also be seen in more detail in FIG. 2 , the excavating device 7 is articulated to the machine frame 2 by means of brackets 13 arranged in the region of the conveyor chain offset 11 . With the help of a drive 14 coupled to the machine frame 2, this brac...

Abstract

A lifting device (7) with a rotatable, endless conveyor-chain (8) for receiving bulk material (9) of a track bed (10) is associated with a machine (1) comprising a machine frame (2) that can be moved on a track (6) during a working advancement (5). A discharging device (12) for discharging the received bulk material (9) and a mounting (13) for connecting the lifting device (7) to the machine frame (2) in an articulated manner are provided in the region of an upper conveyor-chain deflection (11). The mounting (13) is movably supported on the machine frame (2) relative to same in a longitudinal direction of the machine, said mounting moving in a displacing motion (20) that is limited by a front working position (18) with respect to a working direction (4) and by a rear end position (19). The mounting is also connected to a buffering element (21) that is fixed on the machine frame (2), said buffering element enabling a displacement of the mounting (13) together with the lifting device (7) to the end position (19) after a target resistance (22) acting against the displacing motion (20) is exceeded. A switch (25) that detects the displacing motion (20) and the exceeding of the target resistance (22) is designed to interrupt the working advancement (5) of the machine (1).

Description

Background technique [0001] The invention relates to a machine with a machine frame movable by means of an on-track running gear on a working track, an excavating device associated with the frame having blocks for collecting a track bed A rotatable conveyor chain connected end to end for lumpy material, wherein in the area where the conveyor chain on the upper part of the excavating device is offset, a discharge device for discharging the collected lumpy material and for articulated excavating device ground connection to the bracket of the machine frame. [0002] Machines of this type are already known to those skilled in the art, as ballast bed cleaning machines in various embodiments (eg US5926981), and are used to excavate the ballast bed of a track for cleaning or removal purposes . For this purpose, during the continuous working run of the machine, the corresponding conveyor chain is lowered through the track bed into the ballast bed of the track, either under the track...
