Abstract

A system for the rail-bound transport of objects comprises a plurality of coupled-together railway carriages, each of which has at least one transport track provided on a support structure, on which the objects can be moved along the railway carriages and which is designed such that the transport tracks of coupled-together railway carriages adjoin one another, wherein transport bodies are provided for the objects which are designed to be movable along adjoining transport tracks from railway carriage to railway carriage. The support structures of at least two coupled-together railway carriages rest on a common Jakobs bogie in their coupling area.

Description

The invention relates to a system for the rail-bound transport of objects, in particular for the transport of material to and from railway work vehicles, with a plurality of coupled railway carriages, each of which has at least one transport track provided on a support structure, on which the objects can be moved along the railway carriages and which is designed such that the transport tracks of coupled railway carriages connect to one another, wherein transport bodies are provided for the objects which are designed to be movable along adjoining transport tracks from railway carriage to railway carriage.

Work on railway tracks is carried out on the tracks as far as possible, as this minimizes the impact on rail traffic and the impact on the environment. Rail-mounted work vehicles are used for this, such as ballast bed cleaning machines, sub-surface rehabilitation machines and the like, but also machines for dismantling or rebuilding rail tracks. In practically all cases, material must be transported to and/or removed from the work vehicles. For example, with ballast bed cleaning machines, waste from old ballast and sub-surface material must be removed.

By using transport bodies, materials can be transported to and from the construction site in a particularly efficient and pollution-free manner. In addition, there is virtually no segregation of the materials. Another advantage is that all types of materials, in particular water, small iron parts, sleepers and fuel can be transported alongside road material and ballast. However, a system of this type can be used not only for transporting material to and from railway work vehicles, but also for transporting objects on railway lines in general.

The design of the transitions between the railway carriages, especially the transitions between the transport tracks, is complex and costly. A particular problem is the vertical and horizontal offset of the supporting structures and transport tracks in the transition area, which impairs the reliability of transport and reduces the loading volume.

It is an object of the invention to improve transport safety in a transport system of the type mentioned above using simple means.

The problem is solved by a system having the features of claim 1.

According to the invention, the support structures of at least two coupled railway carriages rest on a common Jakobs bogie in their coupling area. As a result, there is no significant vertical offset between the successive support structures. The horizontal offset is also minimized because both support structures can be attached to the same structural element. This improves the mobility of the transport bodies from railway carriage to railway carriage. Since the transition can be made comparatively short due to the Jakobs bogie, a transport system according to the invention also requires relatively little space.

A Jakobs bogie generally has a rail chassis and is designed to support two consecutive wagon frames. The resting of the support structures on the Jakobs bogie refers to the operating state of the system. The coupling area corresponds to the transition area between two wagons, with the detachable coupling generally taking place between the wagon frame of one of the railway wagons and the Jakobs bogie.

The support structures can rest on the Jakobs bogie directly or via at least one adapter element, for example an adapter plate. The adapter element can, for example, be designed for a particularly detachable attachment to one of the support structures. To couple two railway carriages, the support structure with the mounted adapter element is then simply hung in the Jakobs bogie. The adapter element helps to increase stability.

Preferably, the wagon frames of the railway wagons are formed by the supporting structures. This means that the railway wagons are preferably formed by the supporting structures and the Jakobs bogies and do not have any additional wagon frames. A railway wagon of the system can also have one or more additional axles and/or a standard bogie.

One embodiment of the invention provides that the supporting structures of all coupled railway carriages rest on a common Jakobs bogie in the respective coupling areas. In this embodiment, successive Jakobs bogies are each connected by a supporting structure, which is particularly space-saving.

Preferably, coupling means are provided for the detachable coupling of the Jakobs bogie with the supporting structures resting on it. The railway carriages of the system can thus be reassembled quickly and easily.

The coupling means can have pins and pin receptacles that interact with them, which are provided on the one hand on the top of the Jakobs bogie and on the other hand on the support structures or on adapter elements connected to the support structures. To couple two railway carriages together, the free end of a support structure can be lifted with an excavator or the like and placed on the Jakobs bogie in such a way that the pin slides into the pin receptacle. For additional fixation, the pin can snap into the pin receptacle.

The or each Jakobs bogie can include a drive, so that a traction vehicle can be dispensed with. In particular, the Jakobs bogie can be equipped with a hydrostatic drive and/or with an electric drive. Electric drives are easy and precise to control - even at low driving or working speeds.

A special embodiment of the invention provides that the or each Jakobs bogie comprises a crawler chassis. This facilitates the use of the transport system on track-free construction sites, such as at the construction site of a new rail track.

The Jakobs bogie can be designed as a standard freight wagon bogie, for example according to the "Y 25" or "Y 27" type. These types are specified by the International Union of Railways (UIC). The corresponding bogies are standard assemblies and are available at low cost. If the transport system is to be used exclusively on construction sites, used bogies can be used, which is particularly cost-effective.

The support structures may be at least substantially 20 feet long. A relatively short design of the rail cars is advantageous in that there is only slight buckling between the support structures in a track curve. In addition, a close arrangement of Jakobs bogies is advantageous in terms of usable tonnage because the car frames have reduced stability requirements due to their short design and can therefore have a comparatively low weight per unit length. This in turn increases the payload.

A container for energy supply components and the like can be attached to the underside of at least one of the support structures, in particular between two end support sections. In this way, the space between two Jakobs bogies can be used advantageously. For example, a tank, batteries, fuel cells, a power generator, a hydraulic unit and/or an electronic module can be accommodated in the preferably box-shaped container.

On the underside of at least one of the support structures, in particular between two end support sections, a vertical extension can be provided downwards between the support sections in order to increase the static usable height with a low wagon frame. In this way, too, the space between two Jakobs bogies can be used advantageously.

The support structure of one of the railway carriages can have a coupling section via which the railway carriage can be coupled to another railway carriage having a support structure with a corresponding coupling section. In this way, several transport systems according to the invention can be coupled to one another.

It can also be provided that the support structure of one of the railway carriages has buffers and/or a coupling for coupling the railway carriage to a conventional railway carriage or a towing vehicle. As a result, a transport system according to the invention can easily be coupled to a conventional railway carriage or a towing vehicle.

The coupling section can also be provided on a cantilever that extends beyond a bogie and, depending on the application, can interact symmetrically or asymmetrically with the other coupling section. The coupling section could also be formed on a coupling frame that is shorter than the other supporting structures and is supported at one end by at least one axle.

Regardless of the presence of a coupling section, the supporting structures can be mechanically coupled to one another in an upper deck area facing away from the Jakobs bogie. This allows the offset of the supporting structures to be mechanically limited.

The invention also relates to a method for carrying out work on an existing or to be constructed rail track by means of a track construction train located on the rail track, which comprises several coupled railway wagons.

A wide variety of rail vehicles are required for track construction. However, the approval of specially manufactured rail vehicles under railway law is not only a very time-consuming process, but also associated with high costs. In addition, each country has its own relevant regulations that must be observed.

According to the invention, the track construction train is assembled at the work site using individually provided railway wagons, wherein the railway wagons are transported to the work site as a whole or in parts away from the railway track by road vehicles or as general cargo on the railway track by separate freight wagons.

Since the railway wagons are used exclusively as rail vehicles on the construction site track and do not take part in regular rail traffic, they do not require any railway approval. This means that work on the railway track can be carried out particularly quickly and cost-effectively.

A track construction train “located on the rail track” is also generally understood to mean a track construction train that is not completely located on the rail track, but has, for example, a section that is supported directly on the ground by means of crawler tracks or the like.

One embodiment of the invention provides that, in order to assemble the track construction train at the work site, wagon frames and Jakobs bogies are provided individually and that the railway wagons are formed at the work site by rerailing the Jakobs bogies and by placing two consecutive wagon frames on a Jakobs bogie. This can be done quickly and easily using an excavator or crane. Bogies are generally easy to transport, for example on a flat freight wagon.

It can be provided that the railway wagons each have at least one transport track provided on a support structure, on which objects can be moved along the railway wagons, wherein the railway wagons are coupled together in such a way that the transport tracks of coupled railway wagons connect to one another, in particular wherein transport bodies for the objects are placed on the transport tracks. A corresponding track construction train has the advantage that, depending on requirements, different materials can be transported to and/or away from the construction site at the same time using the transport bodies.

The railway wagons can be transported to the work site in a disassembled state to facilitate loading onto freight wagons and road vehicles.

The invention further relates to a system for carrying out work on an existing or to be constructed rail track with a plurality of coupled railway carriages, each of which has at least one work device for carrying out work related to the rail track.

According to the invention, the working devices of at least two coupled railway carriages rest on a common Jakobs bogie in their coupling area.

A work system according to the invention requires relatively little space, since the transition between two work devices can be made relatively short due to the Jakobs bogie. The work devices can be any machine such as cleaning machines, excavation machines, wall-laying machines and the like that are designed to be placed on a Jakobs bogie. These can be assembled at the track construction site in the desired order to form a track construction train.

Further developments of the invention can also be found in the dependent claims, the description and the accompanying drawings.

This in 1 The system 10 shown for the rail-bound transport of objects comprises a plurality of coupled railway carriages 11, of which two complete ones and part of a third are shown as examples. The railway carriages 11 are formed by support structures 13 and Jakobs bogies 15, in such a way that each railway carriage 11 is assigned a support structure 13 and a Jakobs bogie 15. The transitions between two consecutive support structures 13 are to be regarded as coupling areas 17 of the railway carriages 11. As shown, in the operating state of the system 10, the support structures 13 of two coupled railway carriages 11 rest on a common Jakobs bogie 15 and are supported by this on a rail track 19.

Vertical pins 21 are arranged on the top side 20 of the Jakobs bogies 15, which can engage in pin receptacles (not shown) of the support structures 13, so that the support structures 13 can be easily suspended in the Jakobs bogies 15. The pin receptacles can be formed in adapter plates (not shown) which can be detachably mounted on the undersides 22 of the support structures 13.

The support structures 13 can be designed as cuboid-shaped frames made of metal profiles. A lower transport track 26 and an upper transport track 27 are provided on each of the support structures 13, for example in the form of roller conveyors, belt conveyors or the like. Transport bodies 28 can be moved from railway carriage 11 to railway carriage 11 on the transport tracks 26, 27. The transport bodies 28 are preferably transport containers for building materials and the like. The transport bodies 28 can be provided with wheels that roll on the lower transport track 26 and the upper transport track 27. Depending on the application, the transport tracks 26, 27 and/or the transport bodies 28 can be equipped with drives.

Preferably, the lower transport tracks 26 and the upper transport tracks 27 of successive support structures 13 are connected to one another at least substantially without a step and run horizontally. For this purpose, transport track connections could be provided between the support structures 13, which in 1 however, is not shown. Preferably, the support structures 13 and/or the transport bodies 28 are stackable.

The Jakobs bogies 15 can include respective drives so that a traction vehicle for the train of railway carriages 11 can be dispensed with. The Jakobs bogies 15 are preferably designed according to the “Y 25” or “Y 27” type.

At least one of the Jakobs bogies 15 may comprise a crawler chassis to enable use of at least part of the system 10 in a track-free area, which in 1 however, is not shown. It is also possible that at least one of the Jakobs bogies 15 has both a crawler chassis and a rail chassis.

The support structures 13 can have lengths of 10 feet to 80 feet. A length of about 20 feet is particularly advantageous with regard to the resulting payload.

The system 10 according to the invention for the rail-bound transport of objects can be designed as in the 2-7 shown can be composed of several traction units 33. The coupling of two traction units 33 can be carried out by means of special transition modules, for example as in 2 and 3 represented by two short wagons 35, which rest on a Jakobs bogie 15 on one side and are provided with a single axle 37 on the other side, designed for coupling. The sections of the short wagons 35 which project beyond the individual axles 37 are coupled together via couplings 39 in such a way that the vertical and horizontal offset between the transport tracks 26, 27 is minimal. A safe working position for the shunter can be provided for shunting operations.

Alternatively, as in 4 and 5 shown, an asymmetrical coupling of two train units 33 can be provided. For this purpose, an overhanging coupling frame 41 is arranged on an end-side Jakobs bogie 15, which can overlap another end-side Jakobs bogie 15 and be coupled with a coupling plate 43. In the coupled state according to 5 The two Jakobs bogies 15 are located close to each other.

According to another study published in 6 and 7 In the alternative shown, respective overhanging coupling heads 45 are provided on the two train units 33 to be coupled together. These can be coupled to one another, for example, via an automatic train coupling such as a digital automatic coupling (DAK), whereby a data connection is also established between the train units 33 during the coupling process. The coupling heads 45 can serve as a shelter for a shunter.

In the area of the lower transport tracks 26, no significant lateral offset occurs due to the proximity to the pivot point of the Jakobs bogie 15. In the area of the upper transport tracks 27, however, an undesirable degree of lateral offset could occur, especially on ramps or in the case of poor track conditions. To counteract this, the support structures 13 can be designed as in 8th shown in the area of the upper transport tracks 27. The corresponding coupling devices 47 are preferably designed to be foldable so that they can be folded into the interior of the carriage for conveying the transport bodies 28. Either as in the upper part of the 8th shown two lateral coupling devices 47 or as in the lower part of the 8th shown, a central coupling device 47 can be provided. The central coupling device 47 is preferably designed asymmetrically for the purpose of direction independence.

In the 9 In the railway carriage 11 shown, a box-shaped energy supply container 49 for energy supply components and the like is attached to the underside 22 of the support structure 13, specifically in the free space between the Jakobs bogies 15. Depending on the application, tanks, batteries, fuel cells, power generators, hydraulic units and/or electronic modules are housed in the energy supply container 49.

At least one railway carriage 11 of the system 10 can, as in 10 shown have a flat support structure 53 without an upper transport track. Such a support structure 53 facilitates the loading and unloading of transport bodies 28. In order to increase the static usable height in this embodiment, a vertical extension 55 downwards is provided on the underside 22 of the support structure 53.

A flat support structure 63 can be as in 11 shown with buffers 65 and, if necessary, with a coupling (not shown) to facilitate the coupling of a locomotive or a conventional train.

12 shows a Jakobs bogie 15 in an exemplary embodiment. The Jakobs bogie 15 has a rail chassis 71 and defines a vertical axis of rotation 73. Two adapter plates or elongated supports 74, 75 are provided, each of which is arranged on the rail chassis 71 so as to be rotatable with respect to the axis of rotation 73. As shown, the supports 74, 75 are each equipped with vertical pins 21 at the end, which can engage in associated pin receptacles. The pins 21 here have a flattened cross-section, but could also have a different cross-sectional shape. It is understood that instead of the pins 21, other coupling means such as hooks, latches, screws and the like can be provided.

Since the support structures 13, 53, 63 can be easily removed from the Jakobs bogies 15 and both the support structures 13, 53, 63 and the Jakobs bogies 15 are easy to load, the system 10 according to the invention can be easily assembled where material is to be conveyed by means of the transport bodies 28, for example at a track construction site. At one end of the train there can be a railway work vehicle with work equipment for carrying out work on the rail track 19.

Specifically, when carrying out work on a rail track 19 using a track construction train located on the rail track 19, which comprises several rail cars 11 as described above, the track construction train can be assembled at the work site by coupling together individually provided rail cars 11, the rail cars 11 being transported to the work site away from the rail track 19 with road vehicles or on the rail track 19 with separate freight cars, in particular standard freight cars. For this purpose, the support structures 13, 53, 63 can be equipped with container corner fittings. The rail cars 11 are therefore transported to the work site in a disassembled state.

The supporting structures 13, 53, 63 and the Jakobs bogies 15 are individually attached to the construction site. After the Jakobs bogies 15 have been put on the rails, the support structures 13 are placed on the Jakobs bogies 15 in such a way that the pins 21 engage with the pin receptacles. In this way, a specially adapted track construction train can be formed depending on the requirements on site. Since the railway wagons 11 do not have to take part in regular rail traffic, but are only used in the construction site area, no railway approval is required. A particular advantage of the invention is that defective components of the system 10 can be easily replaced.

Instead of supporting structures 13, 53, 63, work equipment such as excavation equipment or other machines can also be provided, with the work equipment of two coupled railway carriages 11 resting on a common Jakobs bogie 15. For this purpose, the work equipment has respective interface sections that match the Jakobs bogie 15. Preferably, the base frames of the work equipment rest on the Jakobs bogie 15 in a similar way to the supporting structures 13, 53, 63.
