Description

The present invention relates to a method for renewing a Track system with a substructure, a bedding, in particular sheet ter, and a track laid on it, or for converting one Track system in a solid carriageway, especially with one on a support layer laid and fastened there or a track with in one Base layer cast sleepers or support plates, in which the Bedding and, if necessary, the substructure to a desired depth removed and at least partially removed and / or cleared be prepared, if necessary material for the new bedding or a Base course of a solid carriageway and, if necessary, for a new one Substructure is transported, the new bedding or a base course for established a solid track, the old track against a new track exchanged and the new track is laid, straightened and fixed. About that In addition, the invention relates to a device for performing a such procedure.

When renewing track systems with ballast bedding, übli Different devices are used sequentially speaking their purpose. So first of all a Direction for the expansion of the old ballast bed and, if necessary, the Substructure threaded into a track system and over a certain one Construction phase driven. Then a track changing device  used that the old deposited by the ballast excavation device Exchange the track for a new track. It is either from the Ballast excavation device or from the track changing device new gravel subgrade was created. The third device is then a Threaded track tamping machine that aligns the new track, ballasted and stuff the gravel.

By requiring at least three devices, one after the other other are used in a construction phase, is the known procedure ren costly and time consuming. It has to go through several operations are performed, each threading and unthreading the used before require direction. This wastes time. In addition, you can the devices used only partially track-bound, so that the delivery and removal of material including surface materials and thresholds must be at least partially done by truck. This represents a severe environmental degradation and brings significant logistical problems with it. In the process of converting a track system These problems are even more pronounced in a solid carriageway.

The invention has for its object a method of ge specified type in which these problems do not exist are. In particular, the method should be less complex and less be environmentally harmful.

This object is achieved in that all process steps from the out build the bedding until the construction of a drivable track layer of the new track in case of renewal or at least until the end provision of a base course for a solid carriageway in the event of a conversion  the track system into a solid carriageway in a single operation be performed.

The implementation of the aforementioned process steps in one Operation has the advantage that only once for these process steps a single device must be threaded into the track system and that these process steps are carried out without interruption can. By including all process steps up to the manufacture If the new track has a passable track position, this also results in Advantage that the supply and discharge of materials in the working direction not only from the front over the old track but also from behind the newly created track can take place. This makes it possible to be practical table to transport and transport all materials track-bound. In order to is on the one hand an impairment of the operation in the neighboring track ver prevents and on the other hand avoided transport by road. It no corresponding construction roads have to be built parallel to the track, and the environmental impact of truck traffic is largely reduced avoided. The rail-bound transport also means less interruptions to the workflow due to weather conditions.

The above-mentioned method steps of one work are preferred gangs carried out in only one direction. A change of direction and the problems associated with it are avoided.

The removed bedding and / or the expanded substructure can be an embodiment of the invention at least partially worked up and for the new bedding or a base course of the slab track and / or a new substructure can be reused. This saves disposal costs  for the existing substances and increases the environmental compatibility of the ver continue driving.

It is particularly preferred if the workup is done on site in the same Operation is carried out. The refurbished materials are immediately available are available and do not have to be transported or removed. Also this increases the environmental impact.

For the refurbishment, the ballast is removed especially from the Bedding material sifted out, broken and sieved by Bre residues exempt. The broken and cleaned gravel can then, if necessary, together with additional new material used as a new bedding.

Another option is to go through the removed material Sieving, breaking and mixing into material for a base layer of a fe refurbish most of the road. For example, an unbound or a hydraulically bound base layer using this mate rials are made. In particular to achieve the requirements A screening line for these base materials can also be required here if necessary, new material is added.

The material supply and / or removal to the construction site is preferably in Ar viewed from both the forward and the forward direction track bound at the back. This makes the transport options so full constantly used as possible.

The expanded and not recycled bedding and possibly Substructure material is preferably viewed forward in the working direction dissipated. Also seen preferably in the working direction  Removal of old sleepers and the addition of new sleepers from behind. This is due to the workflow and portability forth advantageous.

It is also advantageous if the supply of new bedding material and, if necessary, new substructure material and the supply of new material for the production of a base course for a solid carriageway seen from the front in the working direction.

The old bedding and possibly the substructure are removed preferably track-bound. In particular, the old track after the end construction of the bedding and, if necessary, the substructure on the substructure or filed the reason. This is advantageous in terms of process technology.

Another option is to replace the old track after it has been removed the bedding and, if necessary, the substructure on refurbished bed storage material. In this case the bedding becomes immediate processed after removal from the track bed and back into the Track system introduced. An intermediate storage of the track on the Un This makes superstructure unnecessary.

According to a further embodiment of the invention, the rework tion excess bedding material temporarily stored and later reused if necessary. Removal is therefore unnecessary. In addition, this material does not have to be transported in later.

The creation of a new drivable track is particularly important achieved by having the old rails detached from the old sleepers and exposed laterally, the new bedding leveled and compacted, the installed new sleepers, installed rails in front and on  the new sleepers are fixed and that the new track is straightened and stuffed with bedding material. This will be appropriate the future new track system has already been largely manufactured.

If the track system is converted into a permanent carriageway, this will be old tracks prefer on the manufactured base course for the solid carriageway filed. The old track can then be removed in a later step builds and a new track can be installed.

The old sleepers and the new sleepers will be transported before moves longitudinally to the track system. It can also be used for longer periods Thresholds adversely affect the operation on the neighboring track be avoided.

A device for performing the method according to the invention comprises according to one embodiment of the invention several in a row arranged, largely track-driveable parts including a part to Removal of the bedding, a part for the removal of bedding and if necessary substructure material, a drive part or one on the other parts distributed drive, if necessary a part to the transportation of new material, a part to remove the old sleepers and to promote the new sleepers, a track change part as well on the one hand a part for the production of a new bedding and a part for ballasting and stuffing the new track or on the other hand Part for producing a base course of a solid carriageway.

The device according to the invention for renewing a track system is thus largely identical to the device according to the invention device for converting a track system into a permanent carriageway. Difference Lich is only the use of a part to produce a base layer  a solid track instead of the parts to make the new one Bedding and for ballasting and stuffing the new track at the Er innovation of a track system. In the manufacture of such a device this can save costs. When converting the track system in however, unlike renewal, a solid carriageway will not all parts used at the same time. Rather, the part becomes Removal of the old sleepers and promotion of the new sleepers and the track change part only used in a separate operation.

Preferably, the device according to the invention additionally comprises a part for removing the substructure, part for refurbishing the bedding and / or the substructure material, means for breaking and screening the Bedding and / or substructure material, part of the intermediate like the refurbished bedding material, means for stocking and Transport of material for the base course of a solid carriageway and / or a part for mixing the base material. By inte Gration of the parts and resources mentioned, the corresponding Ver driving steps are advantageously carried out on site. In order to recycling of materials is made possible and waste and Transport of material restricted.

It is particularly preferred if the parts of the device at least are partially interchangeable. A device for Renewal of a track system can be done in a cost-effective manner a conversion train for converting a track system into a solid carriageway be rebuilt and vice versa. Essential parts can be taken and do not have to be manufactured separately.  

In particular, the module for producing a new bedding are opposed also the module for the temporary storage of refurbished bed material and, if necessary, the module for supplying new equipment Bedding and possibly substructure material on the one hand and the module for installing a base course for a solid carriageway, if necessary the module for the supply of base layer material and if necessary the module for mixing base material on the other hand against each other other interchangeable.

Fig. 2 is a plan view of the apparatus of Fig. 1,

Fig. 3 is a side view of a device for converting a track system with ballast bed in a solid carriageway and

FIG. 4 shows a top view of the device from FIG. 3.

The device shown in FIGS. 1 and 2 consists of a number of modules that have been put together for the renewal of a railroad track with ballast. Provided and shown in the working direction I, seen from front to rear, is a disposal module 1 , a supply module 2 , a drive module 3 , an excavation and bed processing module 4 , a buffer module 5 , a small egg module 6 , an equilibrium module 7 , a stuffing module 8 , a threshold supply and disposal module 9 and a further supply module 10 .

The disposal module 1 comprises two material conveying and silo wagons 11 for the removal of excavated material in the illustrated embodiment. These each have a conveyor belt 11a and a transfer belt 11 b, and thus can be successively filled with excavated material. Of course, more or less such material conveying and silo wagons 11 can also be provided if necessary. In addition, other facilities for the removal of materials can be used.

The supply module 2 shown also comprises two material and silo wagons 12 , which are, however, arranged in reverse. The mate rialförder- and silo wagons 12 serve the provision and delivery of additional ballast and the forwarding of excavated material to the disposal module. 1 For this purpose, transition bands 12 c are additionally seen. Here, too, more or fewer than two material conveying and silo wagons 12 or other suitable devices can be used.

The device shown is driven by the drive module 3 , which in the example shown is formed by a locomotive-like drive unit 13 . More drive modules 3 can also be provided, or the drive can be distributed among the other modules.

The excavation and bed processing module 4 is divided into an excavation module 4 b and a bed processing module 4 a. As a result, if required, the bed processing module 4 a can be omitted so that only new material is used. The excavation module 4 b includes in addition to the excavation device 14 for expanding the bedding 15 and optionally the substructure 16 also a track lifting device 17 to raise the track 18 during the removal of the ballast 15 and the substructure 16 . The track 18 is then either placed on the substructure 16 or the ground, or the module 4 b additionally comprises a device 17 a, which can preferably be switched off, for producing a new ballast surface, on which the old track 18 is then placed.

The module 4 a for bed preparation includes in particular a pre-screen, a crusher and a secondary screen for removed ballast and substructure and, like the excavation module 4 b, suitable conveying devices 20 a, all summarized with reference number 20th The stages of pre-screen, crusher and post-screen are preferably adjustable as required.

The intermediate storage module 5 is used for the intermediate storage of excess refurbished ballast 19 , which can later be used in the event of a defect for the production of the new ballast bed 26 . In particular, a wagon 21 designed as a ballast silo is used.

The small iron module 6 is used to protect workers who are integrated into the procedure to loosen the small iron with which the rails 23 are fastened to the sleepers 29 .

The track change module 7 comprises a module 7 a a Schwellenaus- and -einbaumodul provided for removal of the old sleepers 29 and for the installation of new sleepers 30, wherein preferably a device to rotate the thresholds 29, 30, so that it is in longitudinal alignment to Gleisan location can be transported. The module 7 a also includes a device 22 for releasing the old rails 23 . The module 7 b serves the direction of the new sleepers 30 , the insertion of laterally upstream ter new rails 24 and the attachment of the small iron.

The ballast tamping module 8 is used to ballast the new track 25 and to tamp the new bed 26 . The new track 25 will also be fine-tuned. Both modules 7 and 8 also have conveyor belts 35 and 36 to promote old sleepers 29 and new sleepers 30 , module 8 additionally a conveyor belt 37 for feeding supplementary ballast from module 10 .

Finally, the threshold supply and disposal module 9 and the ballast supply module 10 serve for the supply and removal of sleepers and supplementary ballast. The threshold supply and disposal module 9 comprises a transfer carriage 27 and a sleeper carriage 28 for stocking new sleepers 30 and for collecting the old sleepers 29 . In addition, gantry cranes are a 28 is provided for transporting the sleepers 29, 30 and the supplementary ballast which can be moved by means of crane rails and drive-over ramps between Schottersilowagen 31 and transfer carriage 27, which A, B with three conveyor belts 27, c for old ties 29, new ties 30 and supplementary ballast provided is. Of course, several Schwel lenwagen 28 can be provided if necessary.

To renew a track system with ballast bed 15 , the device presented Darge is threaded into the track system and used in working direction I. The supply and removal of largely all materia lia is track-bound, namely, the material conveying and Si lowagen 11 and 12 removed and not recycled material seen in the direction of work I transported forward. The old sleepers 29 removed from the track change module 7 , on the other hand, are conveyed to the rear in the working direction I. For this purpose, the old sleepers 29 are deposited in the carriage 28 and transported away with the latter. The new sleepers 30 are also fed in from the rear, as seen in the working direction I. For this they are transported with the sleeper carriage 28 . He also supplementary ballast can be transported from behind via the ballast wagon 31 .

The ballast 15 removed from the excavation module 4 b is screened, broken and screened in the processing module 4 a. 19 a new gravel subgrade 26 may then be prepared with the module 4 b from the reclaimed gravel. For this purpose, new gravel can also be used, in particular for grain supplementation, which is conveyed from the material conveying and silo carriage 12 in the working direction I as seen from the front. On the other hand, arises during the refurbishment of shot ballast 19 , this is stored in the ballast silo wagon 21 in order to be able to be reused in a later need.

In the track change module 7 , the old rails 23 are laterally suspended, the old sleepers 29 are picked up, new sleepers 30 are deposited on the ballast terplanum, new rails 24 are inserted laterally and finally installed in the new sleepers 30 . In the area in which the old rails 23 are put out and the new rails 24 are inserted, the track change module 7 has one or more pairs of crawlers 32 as floor bogies. Otherwise, the track change module 7, as well as all other modules 1 to 6 and 8 to 10, exclusively have rail carriages 33 .

Following the installation of the new rails 24 in the new sleepers 30 , the new track 25 is ballasted in the tamping module 8 , refined and the new bedding 26 tamped. This creates a drivable track that is suitable for the removal and delivery of sleepers 29 , 30 . This means that essentially the entire delivery and removal of material, including old and new sleepers 29 , 30 , can be track-bound. After the old track 18 has been removed, the new ballast planum 26 is preferably replanned and compacted before the new sleepers 30 are installed. The ballast of the new track 25 is carried out in particular with new ballast from the ballast silo gene 31 , which is transported in buckets from the portal cranes 28 a to the ballast conveyor 37 and is transported by this to the tamping module 8 . When a ballast and tamping of the new track 25 , a Rich direction of the track position also takes place. Suitable lifting and straightening devices are available for this purpose, which are not shown here.

The modular structure of the device shown and described also enables a simple design without a device for processing the removed material, if this should not be desired. In this case, the processing module 4 a is omitted. The remaining modules 1 to 10 can also be partially omitted. For example, the intermediate storage module 5 for refurbished ballast 19 can also be omitted.

Another possibility is to put together a conversion train for converting the track system into a fixed carriageway from appropriate modules instead of a device for renewing a track system with ballast bed 15 . Such a compilation is shown in FIGS. 3 and 4.

This renewal train shown in FIGS. 3 and 4 comprises a first part and a second part II III, which are shown here in common, however, be used separately. The first part II is used first in the working direction I, while the second part III is used subsequently and in the opposite working direction IV.

The first part II comprises, seen in the working direction I, from the front to the back, a disposal module 1 , a supply module 2 ', a drive module 3 , an excavation and refurbishment module 4 and a base layer production module 5 '.

The disposal module 1 corresponds to the disposal module 1 of the device shown in FIGS. 1 and 2. The supply module 2 ', however, now consists of two different sub-modules 2 ' a and 2'b. In the module 2 'a is a silo 12' to the provision of cement and water, and wherein the module 2 'b is a silo 12 "for the provision of supplementary material for manufacturing a supporting layer of a fixed track. Both are provided with suitable conveying means 12 'a and 12'b and equipped with transfer bands 12 ' c.

The excavating and work-up module 4 is also consistent with the module 4 of the first device. However, the sieves and crushers are now set up for processing the bedding and, if necessary, underground material on the base course of the slab track to be produced, that is, on the required grain size and composition of base layer material. And the bedding device 17 a is switched off.

An essential difference consists in the module 5 ', which is now also made up of two sub-modules 5' a and 5'b is, specifically, from a mixing device 5 'a for mixing the material for the support layer of the rigid track and a module 5' b to the incorporation of these Base course. The Mischvorrich device 5 'a is used to mix the base material from the refurbished material and possibly supplied new material as well as cement and water.

With the base layer production module 5 'b, a base layer 34 of a solid carriageway, in particular an unbound or a hydraulically bound lower base layer, is produced. The old track 18 is placed on this base layer 34 .

In the case of the conversion train according to FIGS . 3 and 4, the old track 18 is first placed on the substructure or the ground after the ballast 15 and possibly the substructure 16 have been removed. The removed material is worked up as in the variant of FIGS. 1 and 2, but with a correspondingly different grain size in accordance with the prescribed sieve line for an unbound or a bound base layer 34 . Excess material is also transported forward in the working direction I over the material conveying and silo wagons 11 , 12 . To produce the base layer 34 , the refurbished material is mixed, optionally with new material transported in the working direction I from the front from the module 2 'b, and cement and water from the module 2 ' a in the mixer module 5 'a. The base layer 34 is then produced in the base layer production module 5 'b from the finished base layer material.

In order to enable adequate setting of the base layer 34 , the device 5 'b for producing the base layer 34 has a pair of crawlers 32 as a floor undercarriage. In addition to installation, the base layer 34 is also compressed in the base layer production module 5 ′ b. Immediately after the base layer 34 has been produced , the old track 18 is placed thereon.

The second part III of the device according to FIGS. 3 and 4 comprises a small iron module 6 , a track change module 7 , a sleeper supply and disposal module 9 and a material supply module 10 '.

The small iron module 6 coincides with the small iron module 6 of the device according to FIGS . 1 and 2. Like there, it serves to protect workers who, however, now use the small iron to fasten the new rails 24 to the new sleepers 30 .

The track change module 7 also corresponds to the track change module 7 of the previous device. Only the arrangement is now reversed, according to the changed working direction IV, and in module 7 b the small iron is released.

The Schwellenver- -entsorgungsmodul and 9 also includes a transfer carriage 27, a threshold carriage 28 and gantry cranes 28 a.

Thus, the replacement of the old track 18 in a second Ar beitsgang in the working direction IV with largely the same modules that were used in the device according to FIGS. 1 and 2 in one Ar beitsgang in the working direction I. The completion of the solid carriageway is then carried out in a further operation with a suitable device, for example, a solid carriageway with track grating laid on an asphalt or concrete layer or a firm carriageway with sleepers or plates cast into an upper base layer made of concrete.

Due to the modular construction of the device according to the invention, an existing track system with ballast bedding 15 and sleepers 29 of all types of construction can be skillfully renewed in one work step or prepared for conversion into a solid carriageway using various construction methods up to the production of the lower base layer. When producing a solid roadway, a part of the device can also be used in a second operation to replace the old track 18 with a new track 25 . Due to the modular design, the device can be adapted to the respective needs. As a result, the costs remain comparatively low.

The device according to the invention also has the advantage that the delivery and removal of the materials including the old and new sleepers 29 , 30 can take place at least predominantly on the construction track without affecting operation in the neighboring track. By transporting mainly by rail, construction roads running parallel to the track can be saved and truck traffic can at least be reduced. Fewer construction site facilities are required and the environmental impact is significantly reduced. The processing of the removed materials saves disposal costs for existing materials and corresponding transport services. The track-bound transport also means that there are fewer weather-related interruptions to the workflow.
