Description

The invention relates to a machine for dismantling an old and laying a new track, with a first, to a threshold cradle subsequent conveyor for the removal of old sleepers and a second conveyor for transporting new sleepers to a Threshold storage device and a method.

A machine for dismantling an old track and laying a new one Track is known from EP 1 179 635 A2. At the railroad, articulated machine frame existing machine are devices for threshold support and storage as well as threshold conveyors arranged for the transport of old or new waves.

The object of the present invention is now to provide a machine of the generic type, with a simple and cost-saving Incorporation and reuse of well preserved sleepers in the newly laid track is guaranteed.

According to the invention this object is achieved with a machine of the aforementioned Art solved by a transfer device with a through a drive height adjustable transfer member for optional transfer provided by sleepers from the first to the second conveyor is.

With this training, it is now possible, usable sleepers without large Reuse effort. Not all old thresholds have to be done first stored on wagons and stored, then the still usable To sort out, store intermediate thresholds in a time- and cost-consuming manner and to transport it back to the installation site. The re-introduction the sleepers becomes direct with minimal design effort involved in the laying process of the Neuschwellen. The useless old sleepers are stored on wagons and professionally disposed of.

Further advantages and embodiments of the invention will become apparent from the dependent claims and the drawing.

In the following the invention with reference to shown in the drawing Embodiments described in more detail.

another example of a transfer device in a simplified side view.

A machine 1 shown in Fig. 1 consists essentially of a Machine frame 2, which can be tracked on both track carriages 3, as well as tracked by crawler tracks 4 independently movable is. Due to the large length of the machine 1 is the machine frame 2 in two parts and equipped with a joint 5. On the machine frame 2 are a threshold receiving device 6 and a - with respect to a working direction 7 (arrow) - behind it located threshold storage device. 8 arranged. The threshold receiving device 6 is a first conveyor 9 for transporting old sleepers 10, the threshold storage device 8 is a second conveyor 11 for transporting new sleepers 12 assigned. Both conveyors 9, 11 arranged one below the other consist of several, in the machine longitudinal direction or working direction. 7 successively arranged conveyor belts 13.

For optional transfer of old sleepers 10 on the second conveyor 11, a transfer device 14 is provided. This is made up two, jointly a transfer member 15 forming transfer conveyors 16, 17th Together, each - in its normal position - a section of the first or second conveyor 9, 11 form. Each a rotary drive 18 having transfer conveyor 16, 17 is by a drive 19 to a transverse horizontal axis 20 from the normal position (in dot-dashed Lines shown) in a transfer position (shown in full lines) pivotable.

In the following, the operation of the machine 1 will now be briefly described. After the removal of the old sleepers 10 by the threshold receiving device 6 from a track bed 21, the old sleepers 10 with the transported first conveyor 9 against the working direction 7. At the same time Neuschwellen 12 through the second conveyor 11th transported in the working direction 7 to the threshold storage device 8, where they are then stored on the now leveled track bed 21. In this process are the pivotable transfer conveyor 16, 17 in the dash-dotted line normal position in which they respectively form a portion of the first and second conveyor 9, 11.

As soon as a group of reusable thresholds 10 has been added is and on the pivotable transfer conveyor 16 of the first Conveyor 9 is located, both transfer conveyor 16, 17 in the Transfer position pivoted. This creates as it were a transfer bridge (see Fig. 2). At the same time, the direction of rotation of the rotary drive the second transfer conveyor 17 vice versa (opposite to the working direction 7) and the further supply of Neuschwellen 12 set.

Once the mentioned group of old sleepers 10 on the lower transfer conveyor 17 passes, this is pivoted back to the normal position and changed the direction again (now in working direction 7). The old sleepers 10 thus reach the threshold storage device 8, to be stored there again for reuse on the track bed 21 become. This process of the groupwise transfer of old thresholds 10 can be repeated as often as you like. Are the old sleepers 10 unusable, Both transfer conveyor 16, 17 are pivoted back into the respective normal position.

According to Fig. 3, an alternative embodiment is conceivable, as a transfer member 15 only the upper transfer conveyor 16 is used. This becomes the handover Altschwellen 10 höhenverstellt on the second conveyor 11. The lower transfer conveyor 17 is slightly in an inoperative position lowered.

Claims (4)

1. A machine (1) for dismantling an old track and laying a new track, including a first conveyor arrangement (9), adjoining a sleeper pick-up device (6), for transporting away old sleepers (10) and a second conveyor arrangement (11) for transporting new sleepers (12) to a sleeper laying device (8), characterized in that a transferring device (14), having a transferring member (15) vertically adjustable by means of a drive (19), is provided for selectively transferring old sleepers (10) from the first onto the second conveyor arrangement (9,11).
2. A machine according to claim 1, characterized in that the transferring member (15) of each conveyor arrangement (9,11) is a transfer conveyor (16,17) which is adjustable about a transversely extending horizontal axis (20) in each case by means of a drive (19) from a normal position, forming a section of the respective conveyor arrangement (9,11), to a transfer position.
3. A machine according to one of claims 1 or 2, characterized in that a rotation drive (18) of the transfer conveyor (17) associated with the second conveyor arrangement (11) is designed for selective actuation in two opposite transporting directions.
4. A method of dismantling an old track and laying a new track, wherein, in a continuous working operation, old sleepers (10) are transported away in the longitudinal direction of the machine and, parallel thereto, new sleepers (12) are transported in an opposite direction to a sleeper laying device (8), characterized in that old sleepers (10), while being transported away, are selectively deflected for transport in the direction towards the sleeper laying device (8).
