Description

The present invention relates to a railroad work vehicle having a chassis carried chassis and working equipment carried by the chassis.

Work on railway tracks is carried out as far as possible by rail, as this can minimize the impact on rail traffic and the burden on the environment. Used for this are rail-mounted working vehicles such as tamping machines, ballast plows, Schnellumbauzüge, ballast bed cleaning machines, subsurface renovation machines, tarmac improvement machines, recycling planing improvement machines and the like, but also machines for demolition, replacement or re-production of railways. Furthermore, combination machines such as ballast bed cleaning processing machines are used.

In the course of the work carried out by the work vehicles, material transport within the vehicle is required. For example, in a ballast bed cleaning machine, ballast must be transported from the receiving location of the machine to the cleaning facility of the machine and from there to the replacement site. In a railway track rebuild machine, all material, such as gravel, sand, cement, sleepers, iron, etc., must be transported to the appropriate workstation on the machine. Accordingly, in a machine for the dismantling of railways Material be removed from the corresponding workstations of the machine. Also, the transport of a complete track grid away from the workplace or to the workplace may be desired in track construction work.

The EP 1 775 190 A2 discloses a system for transporting ballast as part of a ballast bed cleaning. The ballast is conveyed in this system either on conveyor belts or in bulk containers along a train of railway cars.

The FR 0 089 076 A1 discloses a track construction machine for track renewal or new construction which includes one or more threshold conveyors and a gantry crane.

In the WO 2008/154986 A1 discloses a track construction machine with a pick-up device for iron. The receiving device is composed of two conveyor tracks and a subsequent conveyor belt.

The invention has for its object to provide an advantageous transport option for materials within the work vehicle.

This object is achieved in that below and / or above the working equipment at least one transport path is provided, on which transport containers for objects along the work vehicle can be moved.

According to the invention for transporting materials within the work vehicle so transport body is used in the form of transport containers along the transport path or the transport paths of the work vehicle are movable. This has, inter alia, the advantage that any materials can be transported by the same means within the work vehicle, so in particular bulk material, such as sand, cement, gravel, gravel and the like, but also iron, sleepers, liquids such as fuels, water and whatever else is needed or must be disposed of, so should be transported. Even a transport of general cargo such as rails, sleepers or a complete track grid is possible in a suitably designed transport path. In this case, for example, the track grid itself forms a transport body within the meaning of the invention. The invention also has the advantage that the transport body can be used not only for transport within the work vehicle, but also for the transport of Material over the work vehicle away. For example, fuels on one side of the work vehicle can be transported by appropriate rail vehicles and transported across the work vehicle to a rail vehicle located on the other side of the work vehicle, for example to the drive unit of a supply train.

An advantage of the use of transport bodies instead of conveyor belts is also that there is no segregation of the bulk materials and the pollution is less. Furthermore, different materials can be transported simultaneously on one and the same transport path by being transported in each case in a separate transport body. It is also possible to work flexibly since the transport containers can each be moved individually in each direction as long as the transport path is free in the corresponding direction. But it can also be provided for transport body two or more transport paths. The transport is thus even more flexible. In addition, this makes it possible to reorder the transport body by replacing transport body between the transport paths. In addition to these advantages, the use of transport bodies also increases transport process reliability.

The provision of two or more parallel transport paths allows a continuous supply and / or removal of material by the transport body moved on a transport path to a loading or unloading and filled or unloaded there and loaded or unloaded on another transport path be driven away again from the loading or unloading. It is also preferred if the transport body can be moved on the transport paths in both directions, in particular also individually. The system is special flexible. Incidentally, the transportation lanes may be formed, for example, as lanes, roller conveyors, slideways, suspension railways, overhead conveyors, conveyor belts, conveyor chains or the like.

The use of transport bodies also has the advantage that the work vehicle can easily be formed so that the train traffic on a neighboring track remains possible during use. It is also relatively easy to comply with the work vehicle a predetermined clearance profile during use and / or transport of the work vehicle.

Preferably, the transport body on the transport path without additional Verlademittel such as cranes are movable. Furthermore, the transport body are preferably moved directly on the transport path. Furthermore, the transport path is preferably substantially horizontal. The complex and costly provision of gantry cranes or the like can be avoided.

According to yet another embodiment of the invention, a device for mechanical transfer of transport bodies between the work vehicle and another work vehicle or a transport vehicle is provided at least at one end of the work vehicle, with which material for the work vehicle and / or transported away. Thus, a quick and easy supply and disposal of the work vehicle can be guaranteed.

In principle, it is also possible to provide a lateral loading and unloading possibility for the transport body. As a result, transport bodies can also be removed from the side and exchanged for other transport bodies, for example a transport body filled with discharge material to replace it with an empty transport body, to exchange an empty transport body with another supply with supply material or to take up an old track rust and then to deposit a new track grid. This loading and unloading possibility can also consist solely in that the working vehicle provides access for a loading and unloading device such as an excavator or a lifting vehicle.

The transport bodies can be designed as open or closed containers or as plate-like carriers. Open containers are easy to load while closed containers provide good protection for the transported goods. Plate-like carriers are particularly suitable for bulky goods.

For the loading operation, the transport bodies may be removable from the transport path, e.g. by lowering. In this way, a transport path operation is also possible during the loading process.

To move the transport body along the transport paths may be provided on this a drive, such as driven rollers. However, a drive can also be provided on the transport bodies themselves or elsewhere in the work vehicle, for example laterally of the transport paths. A drive on the work vehicle has the advantage that the transport body can be designed very simple, for example, as a simple transport boxes.

The drives are preferably designed so that with them a cornering of the transport body according to the track curve of the track can be generated and / or that a method of transport body is also possible in gradients, descents and elevations of the track.

This makes it possible to move the transport body on any route.

More preferably, the transport body can be individually and / or in groups and / or moved together. This further increases the flexibility of the work vehicle. Among other things, it is possible to move at slopes less than all transport body at the same time to keep the necessary power and the necessary energy consumption low. The joint mobility allows a fast loading and / or unloading. The Einzelverfahrmöglichkeit facilitates reordering of the transport body.

According to a further embodiment of the invention, the transport bodies can be coupled to one another mechanically and / or by appropriate control. As a result, two or more transport bodies can be moved together in a simple manner.

According to a further embodiment of the invention, the transport body relative to a transport path or the Eisenbahnarbeitsfahrzeug be locked. This can prevent that the transport body move when driving the railway work vehicle by itself.

According to a further embodiment of the invention, the transport body are provided with a machine-readable coding. As a result, the loading and / or unloading process can be automated. Also, according to a further embodiment of the invention, a remote control of the loading and / or unloading of the transport body and the movement of the transport body is possible.

The railway work vehicle can also be designed with an additional loading and / or conveying option for goods such as liquids or gases, in particular pipes which can be coupled to one another. Thus, for example, a supply of necessary water and / or fuel and / or disposal of wastewater can be made possible.

The railway work vehicle according to the invention may be open or have a roof and / or side walls. When providing a roof in particular open transport body are protected against the weather. In addition, the required electrical insulation against a traction current line is guaranteed. By sidewalls weather influences can be further kept away and the aerodynamics of the work train are improved during transfer trips. In addition, the noise pollution decreases.

The railroad work vehicle may also be equipped with a traction drive for running on a track. A locomotive can thereby be dispensable.

The railway work vehicle according to the invention can have a rail and / or ground chassis, in particular a crawler chassis. This is a driving the work vehicle under different conditions possible. Rollers, wheel suspensions, walking gears or other suitable running gears can also be used as a ground running gear. Depending on the amount of support load to be removed such suspensions may include caterpillars, rubber tracks or rubber wheels. The advantage of a walking mechanism is in particular that it requires only a relatively small height. Furthermore, a walker can be easily performed with a relatively large footprint so as to keep the specific surface pressure low. Walking works also allow a comparatively stiff support. In addition to the chassis mentioned above, an auxiliary landing gear for removing additional loads can be provided.

According to a particularly preferred embodiment of the invention, the work vehicle according to the invention consists of two or more modules, each with at least one working device, preferably a group of work equipment for a complete operation such as ballast cleaning, track dismantling, track installation, track renewal, turnout, excavated soil or soil, construction of drainage systems and Lifting, straightening and tamping work. The individual modules can be put together as needed. This effort and cost of a labor input can be kept low. A problem with common work vehicles is that there is a largely rigid structure that allows changes in functionality only limited. A modular design significantly increases flexibility.

According to a further embodiment of the invention, the transport paths are designed to form with transport paths of another work vehicle or module or other rail vehicle with corresponding transport paths each having a continuous transport path. This can be done a simple exchange of transport bodies between the mentioned vehicles or modules.

A method for carrying out work on railway tracks is characterized by the use of a railway work vehicle of the type described above. Preferably, modules of the railway work vehicle are assembled as required to carry out the work. The modules can also be temporarily provided to keep the length of the work vehicle as low as possible. Also, the Modules are changed during the execution of the work, for example, to keep a turnout as long as possible for the rest of traffic or to occupy it as late as possible. Thus, a module arranged at the front of the work vehicle can be converted to the end or another location of the work vehicle when approaching a switch. After passing through the other modules of the work vehicle, the module can then be converted back to the front end of the work vehicle if necessary. Of course, this only works with modules that do not technologically presuppose a particular order of operation.

It can also be provided several identical modules, of which a corresponding number is assembled as needed. For example, one or more recycling modules can be assembled according to the desired intensity and the desired scope of the recycling work.

The use of modules, in addition to the flexibility in the arrangement of the modules has the advantage that the components of the railway work vehicle are relatively small in each case. There is thus the possibility of transporting the work vehicle transportable, in particular verschiffbar.

For transferring several modules common transport components such as wheelsets, their suspension or means for braking or coupling the corresponding train may be provided.

By means of a ground undercarriage as described above, a transfer of a module can also take place if the module does not have its own track chassis. For example, the module could by means of the ground gear onto a wagon train from low-loader vehicles or onto one or more trucks.

The modules can be provided for the transfer operation with a suspension, wherein the suspension is preferably mechanically bridged, in order to ensure greater stability during operation.

In addition, the modules may be provided with a device with which the module floor or mounted on the module devices can be maintained even when driving on elevated tracks and / or tracks on slopes or slopes horizontally.

In certain applications, the transfer of the modules may take place using a train of container wagons on which suitable support plates are located as transport bodies. These support plates are equipped with fixed or easily assembled and disassembled working equipment. Preferably, such support plates are compatible with common standard containers as known in the art. Such support plates may be loaded and transported together with the associated work equipment using the containerized infrastructure in place at many locations.

Furthermore, means for supporting the modules can be provided on the floor. Preferably, this support is exclusively on layers that are either still expand or have already been installed and compacted. The support on the pending floor can be avoided. It is favorable to design the support means in such a way that the specific surface pressure is as low as possible. If the specific surface pressure is less than about the pressure under the Shoe of an operator of the working equipment, so is expected by the support no significant impairment of the substrate.

The modules may each have a device for visual and / or audible warning of the operator before train travel or before movements on the transport path.

Furthermore, the modules may have circulation plates which allow the operator to move quickly from module to module without having to dismount for this.

The modules may also comprise fall protection means, e.g. facilitate the use of the relevant work equipment on bridges.

In principle, the modules can be designed in container construction and be separable from the chassis of the associated railway work vehicle. Such working containers can - temporarily parked stationary without associated railroad cars, for example, as part of a stationary ballast recycling plant or a plant for soil washing. If such a system is completely carried out in container construction, it can be particularly easily transported by sea and / or land. The transport takes place here in an advantageous manner, regardless of the track width of the rail carriageway.

By means of the transport path, the transport bodies can be conveyed along the modules, from module to module, and from working modules to other modules, such as pure transport or logistics modules, which are held on one side or both sides of a working module.

For a multi-module arrangement, a common data exchange infrastructure may be provided. In this way, in particular data regarding the supply or discharge and / or the forwarding of appropriately filled or empty transport containers, energy, supplies such as washing water or fuel, or operating supplies such as lubricant, exchanged and / or forwarded. For example, a master computer can receive information regarding the relevant container contents by means of such data transmission.

The modules can be tailored to specific applications in a variety of ways. For example, a track grid expansion module may be provided.

The load on the rail due to the tensile stress from the bend has, according to experience, been highest in the region of the last wheel set moving on the rail. By appropriately controlled pressure rollers in this area, the bending line of the rail, and thus the maximum tensile stress in the rail, can be favorably influenced.

The iron can be solved by screwing or by violent destruction. A corresponding device for releasing the iron may optionally be carried out easily replaceable. Thus, the track grid expansion module can be easily adapted to different types of iron. The arrival and removal of the release device can be done in a favorable manner by a suitable for this purpose and suitable for transport on the runway transport body. For example, a small iron release device for rare ironmongery types only needs to be held once for several modules and can easily be exchanged between them.

Optionally, the Gleisrostausbaumodul have a device for processing the recorded rails for subsequent transport. Such processing may e.g. the removal of burrs, welds or rust.

In order to produce a grounding carried out by the machine, it is optionally possible to provide an easily contactable surface by means of appropriate removal of material, for instance on the later travel surface of the rail.

Optionally, a device for cutting the removed rails can be provided. Splitting the rails into small pieces may be required to allow the rails to be received in a container.

Furthermore, the track rust removal module may include means for separating the ribbed panels from the associated timber or concrete sleepers and, optionally, means for removing the head bandages of the wooden sleepers. Thus, e.g. Wooden sleepers should be prepared directly on the track grate extension module for thermal disposal. Also, the removal of the sleepers can be particularly space-saving.

A major advantage of the Gleisrostausbaumoduls is that apart from a relatively short distance during threading completely waives wear-prone roles, such as those used in the rail support tongs of the known ballast bed cleaning machines for use.

The track rust removal module may also include a device for detecting the geometric data of the track prior to removal. This device may be configured to store the acquired geometric data in relation to other geometric data, such as e.g. to set fixed measuring points. This data can be used by a control device or an operator when installing the new track grid.

There may also be provided a device which photographically documents the condition of the track prior to removal. The data thus obtained can serve as the basis for any supplementary claims.

Furthermore, the track grid extension module can have a device which is designed to photographically document the condition of the removed sleepers and / or the removed rails.

According to a further embodiment of the invention, a bulk material removal module is provided. Such a module takes the track bed a layer of gravel and / or a layer Planum. The removal of the bulk material takes place here in an advantageous manner with a spoon as in a wheel loader. Such a Aushublöffel is compared to a commonly used Aushubkette a simple component whose wear is less than the wear of a chain. In addition, a worn spoon can be easily and inexpensively repaired, e.g. by welding. A complete replacement of the spoon is also possible quickly and inexpensively. The exchange of a Aushubkette is in contrast much more complex and expensive.

The attachment of the spoon to the machine can be done with a quick-change lock, which makes it possible that a spoon change partially or fully automatically and in particular on site on the site can. The delivery and removal of the spoon can be done with a special transport container on the transport path of the bulk material expansion module. In this way, in construction site operation, for example, a wide spoon can be easily exchanged for a small spoon, or vice versa. Likewise, a spoon with fangs can be exchanged for a spoon with cutting edge, or vice versa. The spoon could also be exchanged for another implement such as a hammer, a drill or a hammer drill.

A precise guidance of the spoon can be accomplished with a guide device in Hexapodbauweise. Furthermore, a walker can provide the necessary traction to guide the spoon.

The emptying of the spoon can be done by gravity or at least temporarily enforced. Forced evacuation avoids that highly clay-containing material sticks in the spoon.

The spoon can be controlled manually, remotely or automatically depending on the application. Manual control can be carried out by means of a control unit, which can optionally be mobile or permanently installed. A fixed operating unit can be mounted in a control station, either process-oriented in front of the bucket or result-oriented behind the bucket.

Manual control can be assisted by auxiliary functions such as an electronic depth stop. Likewise, a device may be provided which prevents the unwanted penetration of the spoon in the clearance profile of a mile track or more miscellaneous tracks.

Preferably, behind the excavating spoon, there may further be provided a device for detecting metals hidden in the ground such as e.g. Be provided duds.

The bulk solids removal module described above can be easily adapted to other tasks such as pulling side or center trenches.

Preferably, the bulk material removal module allows the intermediate storage of a certain amount of material removed. As a result, the transport of the transport body on the transport path can be further optimized.

If required, the bulk material removal module can also include a lifting chain or a bucket elevator.

In particular, in a multi-layer expansion, an arrangement of several juxtaposed bulk solids expansion modules may be provided. In principle, however, it is also possible, with a correspondingly slow progress of work, to expand two or more layers with a single bulk material expansion module.

It may also be provided a device for weighing the loaded transport body. This device could also be designed to determine the center of gravity of the loaded transport body.

Furthermore, a bulk material expansion module could have a device for geometric measurement of the ground before and / or after excavation.

A bulk material removal module may further comprise a device for determining the carrying capacity of the ground before and / or after the excavation.

In addition, a device for photographic documentation of the substrate before or after the excavation may be provided.

According to a further embodiment, a bulk material insertion module is provided, which is designed to remove the transport path at least one loaded transport body, to empty it into a storage bunker and then to install the contents of the transport body and optionally to compact.

The bulk storage module may be configured to incorporate one or more layers of geotextile, geogrid and / or polystyrene panels. The material required for this purpose can be conveyed in an advantageous manner by means of transport bodies on the transport path. During emptying of the transport body can be removed from the transport path.

The bulk material insertion module may further comprise a device for chemically strengthening the upper and / or a lateral layer or two lateral layers. For chemical strengthening, in particular a lime layer or a cement layer can be applied.

The bulk material insertion module can also have a device which is designed to compress the edge or the two edges of the built-in layer in front of the head, ie laterally to the left and / or right.

Furthermore, the bulk material installation module may include a device for determining the moisture of the bulk material to be incorporated, a device for the defined moistening of the bulk material to be incorporated, a device for washing the ballast, a device for compacting the ground ballast bed, a device for detecting the compression parameters and / or a device for detecting have the built bulk amount. Incidentally, the bulk storage module may be provided with the same auxiliary and auxiliary devices as described above with respect to the bulk material removal module.

According to a further embodiment, a combined bulk material input and output module is provided which combines the functionalities of the bulk material expansion module with those of the bulk material module. Such a module is preferably placed in the middle of the building tip modules, at their lowest point, in the working configuration. With such a combined module, on the one hand, the length of the deepest section of the construction site can be kept relatively short and, on the other hand, the load transfer on the pending ground can be avoided.

A combined Bulkgutein- and -ausbaumodul may be equipped on the left and / or on the right with a migratory Verbau. The module can be designed in particular separable.

According to a further embodiment, a track-laying module is provided, which removes at least one transporting body with, preferably new, sleepers from the transporting track and, with the addition of rails likewise conveyed, mounted a track grid.

The track rock module may include a device for detecting, monitoring, and optionally recording assembly parameters such as Tightening torque and the angle of rotation of the sleeper screws, a device for photographic documenting the mounted track grid, a device for grinding or milling the rails of the rails, a device for profiling the rail heads by grinding or milling, a device for connecting the rail sections to be installed before installation by means Flash butt welding and / or have a device for measuring the zero voltage temperature.

Optionally, the track frame module may comprise a device which is designed to install the rails with zero voltage. This can be done by warming about by means of inductance or thermal radiation.

A track rock module as described above is capable of laying the new track grid so that it comes to rest relatively significantly relative to the old previously removed track grid. In conventional machines this can be achieved at most a few decimeters offset. By contrast, with a track-laying module as described above, an offset of more than one meter can be achieved. Mechanically, this is accomplished by the steering functionality, which is needed anyway for working in curves. However, the measurement technique must be designed for the large offset.

According to a further embodiment, a ballast supplementing, stuffing and straightening module is provided, which stuffs the deposited track and possibly makes a gravel supplement. If necessary, a compaction of the ballast in front of the head can be carried out parallel to the stuffing process.

The supply of ballast is preferably carried out by tilting the contents of at least one delivered by the transport path transport body. The device for tilting the ballast can optionally be made separable from the stuffing device. If the stuffing module is used in a working configuration with several other modules, a fixed coupling is preferably provided so that the transport path between the two modules is not interrupted. If the tamping module works alone, the ballast supply module can be coupled in such a way that the tamping module can move by a few meters independently of the ballast supply module. If the stuffing module is to be operated in a manner similar to a conventional stuffing machine without ballast feed, it is also possible to dispense with carrying a ballast supply module.

If two or more stuffing modules are used in a work configuration, they can be supplied by a ballast supply module with supplementary ballast.

The ballast supplementing, stuffing and straightening module may comprise a device for detecting and documenting the stuffing and / or straightening parameters.

Incidentally, the ballast supplementing, stuffing and straightening module can be equipped with the same auxiliary and additional devices as already described above.

According to another embodiment, a soil improvement or rock outcrop module is provided, which is adapted to apply lime and / or cement on the upcoming planum and to mill in this. A milling drum provided for this purpose can also be used for milling out rock.

The material to be introduced can be transported in an advantageous manner by a specially adapted transport body. In order to further optimize the operation on the transport path, the transport body can be temporarily removed from the runway if necessary.

According to a further embodiment, an energy module is provided which supplies additional modules of different types with, in particular electrical, energy.

In addition to generating electricity by means of a diesel engine, a fuel cell or a gas turbine could also be provided for the power supply. Optionally, the supply of electric power can also be done via an existing overhead line.

The refilling of the fuel tank of the energy module can be done with a content of a conveyed on the transport path transport body. If desired, the transport body can be removed during the transfer of the fuel from the transport path. Optionally can thus be dispensed with the fuel tank of the power module, since the supply of the energy module can be done directly from the tank of a transport body.

Furthermore, a control, control and documentation module can be provided in which centrally all work parameters are defined and all measured values are monitored and optionally documented. Optionally, this module can be equipped with means for, preferably chemical, analysis of material or liquid streams.

Viewing windows for viewing the metabolism on the transport path and / or for viewing the long rail transport in a long rail transport device can also be provided.

According to a further embodiment, a bulk material discharge module is provided. If bulk materials such as excavated ballast or expanded tarpaulin material are to be recycled, the bulk material in question is first removed from the transport container. For this purpose, at least one transport body is temporarily removed from the transport path and its content is dumped in a container within the module. In the following, the dumped bulk material with a conveyor such as a belt conveyor is transferred as volume flow to another module.

During the excavation process by means of a lifting chain, a separation of the ballast from the adhering contamination already takes place. It is to be expected that when digging with a spoon, this separation does not take place to the required extent. The ballast transfer module can therefore be optionally provided with a device by means of which this separation process is effected, e.g. by the introduction of mechanical energy.

Optionally, the bulk material discharge module can be equipped with a device for measuring the volume flow and / or the mass flow.

Optionally, a memory for the bulk material to be tipped can be provided. Thus, the movement of the transport body can be easily optimized on the transport path.

Furthermore, a bulk material processing module can be provided, in which a dry, partially wet or wet ballast recycling process takes place.

Furthermore, a bulk goods loading module can be provided which, after or during processing as part of a recycling process, loads the bulk goods in question into transport bodies for removal. Such a bulk loading module preferably loads one e.g. conveyed by a conveyor belt material flow in at least one of the transport path taken transport body.

Optionally, such a bulk material loading module can have a device which passes through a stream or several streams and transfers it to a subsequent module.

All the modules described above preferably operate with a continuous flow of material. However, a batch-wise process may be more suitable for processing small amounts of material, such as those incurred during turnout conversion.

Some of the modules described above can also perform tasks for other modules. Thus, individual modules can include a power supply and thus provide other modules with energy. Also, a drive means may be provided only in one or a part of the modules to move the railroad work vehicle. According to a further embodiment of the invention, the railroad work vehicle may have a weight force management in order to carry out a removal of the weight force over a part of the modules. This has the advantage that individual modules temporarily have to remove any weight. This is especially at the beginning and end of the construction site as well when passing through discontinuities and for maintenance and repair purposes advantageous.

Finally, the transport bodies can also be weighed before and / or after filling and / or after emptying in order to determine and, if desired, document which quantity of which transported goods has been installed or removed at which location.

All variants and embodiments described above are essential to the invention, both individually and in any combination, and thus each form a subject of the invention.
