Abstract

A machine for cleaning a ballast bed has, in front of a take-up device relative to a working direction, a first signal receiver—suitable for position determination in a global navigational satellite system—for scanning an actual track position. A second signal receiver connected to the machine for scanning a new track position created by laying down the raised track onto the re-applied ballast bed is arranged downstream. Both signal receivers are associated with a control device designed to act on the drives that displace a track-lifting device relative to the machine frame.

Abstract

In a method for repairing a subgrade of a rail bed, the rail bed is removed in two stages in the form of an upper ballast layer (4) and a residue processing layer (7) thereunder. The upper ballast layer (4) is then cleaned, with accumulation of ballast (9) and spoil (10), wherein usable spoil (10) is dumped onto an exposed subgrade (11), levelled and compressed to form an intermediate layer (14). Gravel (17) is added to the usable spoil (10).

Abstract

In order to renovate a ballast bed (2), a, in terms of a working direction (5), first clearing device (6) takes up an upper, re-usable bed layer (7) and feeds it to a cleaning system. The gravel (16) which is sieved out in the process is discharged onto the sub-grade (9) behind the second clearing device (8) in the working direction (5) in order to manufacture a gravel layer (15), is levelled and compressed. In parallel with this, residual gravel (25) which occurs as a result of further cleaning processes of the ballast (17) which can be re-used is discharged onto the track (3) in front of the first clearing device (6) in the working direction (5) and is taken up by the first clearing device (6) in conjunction with the upper bed layer (7).

The jaw mount (14), intended for fixing the clamping jaw (6), has a sliding surface (18), which is curved in a way corresponding to the sliding surface (16) of the clamping jaw (6), and so the clamping jaw (6) is movable along the sliding surfaces (16, 18) in relation to the jaw mount (14).

Abstract

For the purpose of refurbishment, a ballast bed (2) of a track (3) is taken up and cleaned in the form of an upper ballast layer (14) by a first clearing device (6). Bulk material (17) which is produced in the process is ejected laterally onto the ballast bed (2) in a bed zone (21) in front of the first clearing device (6) with respect to the working direction (5). Said bed zone (21) can only be picked up by the second clearing device (7), which is of wider design than the first clearing device (6) in the transverse direction of the track. This permits bulk material (17) which is produced in a front end region of a machine (1) to be intermediately stored for later use on the ballast bed (2).

Abstract

The invention relates to a method for correcting a track bed consisting in backfilling said track (8) in such a way that it is placed in provisionally theoretical position, in subsequently controllingly lowering said track in a final theoretical position in the frame of said track stabilisation by applying a vertically acting load to which vibrations are integrated. Gravel (19) is distributed by means of a rotatable sweeping brush (14) in order to obtain a desired homogenous ballasting of the track (8). The gravel (19) arranged in the slipper intermediary area is tamped by the action of the load and vibrations along different operations after the track stabilisation and after the sweeping brush (14) passage. Said final tamping of the gravel surface makes it possible to prevent gravel projections generated by high speeds of a train.

Abstract

A track maintenance machine is equipped with a soundproofing wall (10) adjustable relative to the machine frame (4) by means of drives. The soundproofing wall (10) comprises an upper and lower end (8) as well as two lateral ends (9), spaced from one another with respect to a longitudinal direction of the machine, which connect the upper to the lower end (8). The lower end (8) is formed by a flexible lower soundproofing section (11), consisting of elastic material, which has an upper end (12) spaced from the lower end (8) and connected to a rigidly formed upper soundproofing section (13).

Abstract

A method of loading several like loading wagons (1) coupled to one another to form a loading train (15), each having a bottom conveyor belt (6) and a projecting transfer conveyor belt (10), is carried out automatically. To that end, the transporting speed of the bottom conveyor belt (6) is adjusted, in dependence upon a quantity of the discharged bulk material (16) detected by a measuring process, in such a way that the storage wagon (1) which is in the storage operational mode S is filled with a maximum loading height (h max). After a front-most dump cone (18) of the discharged bulk material (16) reaches a front end position (E), a transporting speed of the associated bottom conveyor belt (6) on the rear storage wagon (1), with regard to the transporting direction (8), adjoining with its transfer conveyor belt (10), is automatically reduced from through-transport operational mode (D) to storage operational mode (S).

Abstract

A storage wagon (1) for bulk material (16) consists of a loading container (5), mobile on on-track undercarriages (2) and comprising a bottom conveyor belt (6) extending in the longitudinal direction of the wagon, which has a transfer conveyor belt (10) adjoining the bottom conveyor belt. The transfer conveyor belt (10) projects over a front end (12) of the wagon for transferring stored bulk material (16) onto a preceding, further storage wagon (1). Provided in the loading container (5) is a sensor device (20) for detecting the filling state, the sensor device being arranged in the rear end (19) of the loading container (5) with regard to a transporting direction (8) of the bottom conveyor belt (6). The sensor device (20) serves for detecting a maximum loading height (h) of a dump cone (18) formed by the bulk material (16) discharged by the transfer conveyor belt (10) of a storage wagon (1) following behind. The sensor device (20) is connected to a control device (23) for automatic actuation of drives (7,13) of the bottom- and transfer conveyor belt (6,10).
