Description

The invention relates to a work train for rehabilitating the track consisting of rails in the form of long rails and sleepers as well as consisting of gravel and a ballast base track substructure of a railway line according to the preamble of claim 1, and a work car according to the preamble of claim. 8

Railway lines basically consist of a track substructure and a track superstructure. The track substructure consists of at least two layers, namely, for example, a gravel layer and a layer protection layer and / or frost protection layer. This track substructure must be rehabilitated from time to time. The track superstructure consists of the track, namely the sleepers and the rails. Also, this track superstructure must be rehabilitated from time to time.

The previously known methods for refurbishing the track substructure and the track superstructure are all ineffective from the workflow ago. Thus, there is always a work-related caesura between the renewal of the track substructure and the work following renewal of the track. Also, there is always the problem of the supply and removal of the necessary building materials.

The DE 20 23 979 A1 shows a method and apparatus for continuously replacing or renewing the thresholds and possibly the rails of a track. Here, in the middle area of the work train, the work station with the removal and installation of the ballast and with the removal and installation of sleepers. Crucial is that the entire logistics of the thresholds on one side of the central job done, while the entire logistics of the ballast takes place on the other side of the central job.

The DD 240 043 A1 shows a ballast bed cleaning machine. This machine removes the ballast bed, cleans the materials and then rebuilds these cleaned materials. The track itself remains untouched.

The EP 0 255 564 A1 shows a machine for replacing or renewing the rails and sleepers of a laid track. The rails, sleepers and ballast are renewed.

The WO 2007/017309 A1 shows a machine for renewing a track. This has on the one hand between an upper and a lower threshold transport unit and on the other hand between a ballast pick-up device and a ballast distribution device extending in the machine longitudinal direction ballast conveyor belt. This is equipped with a discharge end, which is positioned with respect to its working direction behind a device for storing new rails on Neuschwellen.

The invention has for its object to provide an improved work train for refurbishing the track consisting of rails in the form of long rails and sleepers as well as consisting of gravel and gravel underground railway track of a railway line.

The technical solution is characterized by the features of claim 1.

As a result, an improved work train for rehabilitation of the track and the track substructure of a railway line is created. The basic idea is that the work no longer has to be carried out sequentially using different machines always in succession, but according to the invention, the total renovation in the context of a total work process in one and the same system is possible. This means that a track-bound track renewal with respect to the long rails and the sleepers with a track-bound ballast cleaning / ballast renewal as well as with a track-bound tarmac improvement, d. H. Renewal of the substructure below the ballast in a continuously on the track moving forward work train with a continuous workflow of the individual works described above are summarized.

The basic idea of the invention is to equip the work train with at least one so-called threshold wagon with conveyor belt technology. The basic idea of this work car is that on the one hand it creates the opportunity to deposit the old and the new thresholds on the other hand, but also due to the conveyor belts a removal and in-transport of the materials of the track substructure is possible. As a rule, several work cars are arranged one behind the other. This means that the conveyor belts create a seamless transition between the work cars. This special work car thus has the property that the materials to be removed or built in the track substructure below or above the sleepers to be transported can be transported or driven through. The number of work cars is variable and depends on the track length per shift. The conveyor belts of these work cars are variably adjustable in the running direction, ie they can move forward or backwards to run. As mentioned previously, the conveyor belts of the individual work cars are coupled during work, so that a transport of the materials over a longer column of work cars is possible. If necessary, a pickup truck can be attached in front of the work car or behind the work car. This recording carriage allows the supply / discharge of transfer bands with or without Zwischenpufferungsmöglichkeit.

The development according to claim 2, a work train for renewing the track substructure and the track superstructure is created in railway lines, in which without the occurrence of logistical transport problems for the materials for the track substructure and the sleepers and tracks for the track superstructure in a total work process a renewal in a continuous Working procedure can be performed. Because in order to enable all technical steps for the renewal of the track substructure with the simultaneous mechanical conversion of the track superstructure, it is necessary to line up the sleepers or rails on suitable railway carriages in the machine equipment. During the excavation of the work train, no standstill must occur. Since during the reconstruction the materials to be excavated as well as to be installed are supplied from the same direction as the sleepers and rails, it is necessary here to allow suitable transport routes to intersect the sleepers and rails with the materials to be removed from the track foundation. The basic idea lies in the fact that different conveyor paths are provided along the work carriage for this transport of the corresponding building materials. Thus, a combination of the renewal of the track foundation is created with simultaneous renewal of the track superstructure.

Often, there is no need to replace the existing thresholds with new ones. These can be reused after the renovation. For this purpose, the development proposes according to claim 3, the intermediate storage of these reusable thresholds. Thus, before renewing the track substructure, the rails (long rails) next to the machine can be spread out in a continuous workflow and then spread back under the machine. The thresholds can be expanded and installed in spread-out rails. Furthermore, the renewal of the track substructure during this spread out state of the rails is possible. This track renewal is thus now in connection with the rehabilitation of the track substructure in one step.

In the previously known and proven technique can according to the embodiment in claim 4, the old rails after their removal and / or the new rails before her Installation to be placed laterally of the railway line. This placement of the rails takes place before or after the above-described renovation work.

As already mentioned above, instead of the complete removal of the rails according to the embodiment of claim 5, it is also possible that, when using the old rails, they are spread out and then spread in again.

In order to be able to easily transport the developed sleepers and the new sleepers to be installed, according to the embodiment of claim 6, a gantry crane movable along the work car is provided. For this purpose, the work cars have rails on the side. For this purpose, the gantry cranes of the underground remediation machine can be used. You can drive away in the manner described above on the work car to allow the assembly of these work cars with old single sleepers.

The development according to claim 7 proposes various ways of arranging the conveyor belts along the work car. In principle, the materials of the track substructure below and / or above the sleepers to be transported during the stem can be transported or driven through. The change in the variation of the conveyor belts is freely selectable here. It is only required that the transport routes of the sleepers on the one hand and the materials for the track substructure on the other hand do not interfere.

The track substructure 2 consists of gravel and possibly a layer protection layer and / or an antifreeze layer.

On this track substructure 2 is the track 3 consisting of sleepers 4 and rails 5 in the form of long rails.

• Mittels des Arbeitszuges 1, welcher kontinuierlich vorwärtsbewegt wird, wird zunächst das Gleis 3 mit seinen Schwellen 4 und Schienen 5 derart entfernt, daß der Gleisunterbau 2 zugänglich ist. Zu diesem Zweck können die Schienen 5 im Arbeitsbereich entweder vollständig entfernt oder aber seitlich ausgespreizt werden, so daß anschließend die Schwellen 4 mittels entsprechender Maschinen ausgebaut werden können. Diese Schwellen 4 werden auf dem Arbeitszug 1 zwischengelagert. Danach kann der Gleisunterbau 2 erneuert werden, indem zunächst das alte Material entfernt und durch neues Material ersetzt wird. Anschließend erfolgt wieder die Aufbringung des Gleises 3. Der Transport des Materials des Gleisunterbaus 2 erfolgt längs des Arbeitszuges 1 mittels Förderbändern 8.

The operation is as follows:

• By means of the work train 1, which is continuously moved forward, the track 3 with its sleepers 4 and rails 5 is first removed so that the track substructure 2 is accessible. For this purpose, the rails 5 in the work area either completely removed or spread out laterally, so that then the thresholds 4 can be removed by means of appropriate machines. These sleepers 4 are stored on the work train 1. Thereafter, the track substructure 2 can be renewed by first removing the old material and replacing it with new material. Subsequently, the application of the track 3. The transport of the material of the track substructure 2 takes place along the work train 1 by means of conveyor belts. 8

The - extended - embodiment according to the invention in Fig. 2 again shows a work train 1, but this time with targeted use of special work car 6, as described in detail in the Fig. 3 to 6 are shown. These work cars 6 basically have a bearing surface 7 for sleepers 4 and also conveyor belts 8, which extend in the longitudinal direction of the work carriage 6. Furthermore, the work car 6 rails 9 are assigned for a gantry crane of the work train 1 for transporting the thresholds 4.

• Wie bei der ersten Ausführungsform werden während des kontinuierlichen Vortriebs des Arbeitszuges 1 zunächst die Schienen 5 sowie die Schwellen 4 des Gleises 3 des Gleisoberbaus aus dem Bereich des Gleisunterbaus 2 entfernt. Zu diesem Zweck werden die Schienen 5 entweder vollständig herausgebaut oder ausgespreizt. Die Schwellen 4 werden mittels des zuvor beschriebenen Portalkrans auf den Arbeitswagen 6 deponiert.

The operation is as follows:

• As in the first embodiment, during the continuous propulsion of the work train 1, the rails 5 and the sleepers 4 of the track 3 of the track superstructure are first removed from the area of the track substructure 2. For this purpose, the rails 5 are either completely removed or spread out. The sleepers 4 are deposited on the work car 6 by means of the gantry crane described above.

After the track substructure 2 is now free, can be expanded with appropriate equipment, the materials 2 of this track substructure and transported away by means of the conveyor belts 8 of the work car 6. With the other conveyor belts 8 of the work car 6 new material can be supplied and introduced in the corresponding work area.

After the track substructure 2 is restored with new material, then new sleepers 4, which are stored on the work car 6, transported by means of the gantry crane and deposited by appropriate equipment on the track substructure 2. Subsequently, the rails 5 can be mounted.

It is therefore essential that the transport of the sleepers 4 on and along the work carriage 6 and their storage on the bearing surface 7 do not interfere with the transport of the materials along the conveyor belts 8 for the track substructure 2.

Fig. 3 shows a first variant of the work cart 6. In this case, the two conveyor belts 9 extend below the bearing surface 7 for the sleepers. 4

Fig. 4 shows the variant that the one conveyor belt 8 below the bearing surface 7 and the other conveyor belt 8 above the thresholds 4 runs.

The variant in Fig. 5 shows that both conveyor belts run above the thresholds 4.

The variant in Fig. 6 Finally, the in Fig. 3 , after which both conveyor belts 8 run below the bearing surface 7.

In the illustrated embodiment, two conveyor belts 8 are provided. Of course, more than two conveyor belts may be provided.
