EP3299244B1 - Track-bound freight wagon for transporting stand-alone transport vehicles - Google Patents

Description

The invention relates to a freight wagon for the track-bound transport of at least one self-sufficient transport vehicle, in particular a truck with a semi-trailer or the like load transporter, according to the preamble of claim 1.

Different solutions have long been known for the realization of a combined transport system based on the "roll on - roll off" concept for the combined use of road and rail. According to DE 38 38 268 A1 Such a method is proposed for the relocation of road-bound HGV units for track-bound transport. In this case, the intermediate space between a loading area of the freight car and the platform level bridging loading ramp is used, such that by means of a provided on the road vehicle transverse landing gear, in particular the loading of a semi-trailer can be achieved.

In DE 41 20 906 A1 A piggyback system for trucks on railways is proposed whereby a train entering the station is automatically disassembled with wagons and then the individual wagons or platforms are moved so as to allow trouble-free simultaneous loading and unloading of the road vehicles. This computer-controlled system is constructed in such a way that a reduction of the loading times can be achieved.

Also in DE 41 23 339 C2 a system is proposed for loading and unloading of land vehicles for their transport on the rail trawl, with only low-floor wagons being usable on a known system. Here, a stationary, remotely controllable multi-function unit for fine positioning of low-floor cars, for unlocking and locking the loading platform of the low-floor car and for swinging and swinging the loading platform is provided below the railway track. In this case, the system has a disadvantageously high-building construction on the low-floor wagons realizing a piggy-back structure.

In a combined load transport according to DE 44 06 461 A1 a system is used in which a parallel transhipment track is to be arranged at a small distance to a through-track in the area of a transhipment station. In this system, a movable handling unit is integrated, which is used for temporarily receiving the load to be loaded on a freight train or to be unloaded by this load transporter. The load transporter is transferred from the transhipment unit to the freight train or vice versa with the help of an additional pallet.

In a solution according to DE 44 30 118 A1 A low loader railroad car is used for "roll on - roll off" traffic, and this specific low - loader railroad car - corresponding to the low - floor - wagons - is provided with a rotatable bridge that can be moved sideways around a central pivot point so that the truck can access this bridge ascend by means of loading ramps or can leave the vehicle with its own power.

In a cargo system with rotating bridges for loading and unloading of motor vehicles on trains according to DE 195 46 300 C1 a bridge, which can be swiveled between two low-floor chassis, is also used. This bridge is provided centrally with a swivel foot and has a lifting device in the region of the front and rear chassis, so that the end-side connector of the bridge can be released from a transport position and then the one-piece bridge can be pivoted. Although a secure fixing of the pivotable bridge is possible with this lifting device in the region of the two chassis, but this has a constant installation height in the area of the swivel base, so that the application of this bridge construction is limited to a system of a Eurolastzuges. In this case, the train must be solved in total in this system to realize the loading and unloading. This is associated with a disadvantageously high expenditure of time.

A system with a loading bridge is also used in a solution according to DE 100 10 782 A1 proposed, this system is adapted to the specific conditions of container transport and a respective truck trailer with container in the transverse direction can be moved to the transport car.

In a system for loading and unloading of land vehicles for their transport by rail according to DE 199 49 201 C2 The loading platforms are operated by low-floor vehicles by means of a multi-functional element in the center of a Gleistraverse. This system is designed to be in a change position positioned low-floor wagon can be pivoted about its central support axis by means of a Gleistraverse and thus the raising and lowering of land vehicles on the low-floor wagon is possible. An extension of this system is in DE 101 18 510 C1 shown, in which case only a structural adaptation of the system described above is proposed.

Also in DE 20 2009 008 233 U1 a system for a low-floor car is shown, wherein between the front bogie and the rear bogie the lowered frame part can be displaced so that a fixation on the end bogies is possible. In this case, a special lifting system with a rotary and a lifting cylinder is arranged on the base, so that the safety during loading and unloading of transport vehicles is improved by a synchronization of the support cylinder for the loading area. In this case, a system known as TALBOT frame is used, so that the high-building construction similar DE 41 23 339 C2 arises; with the disadvantages regarding height, maximum speed and load capacity of the freight car.

DE 41 12 995 A1 shows a railway car for the transport of trucks with frictionally suspended tray, which is lifted for loading and unloading by means of a located in the track stationary lifting device from the car. Such a car can only be driven on a head ramp, resulting in long loading and unloading.

In DE 601 29 958 T2 discloses an oblique loading system for wagons in a rail and rail transport combined railway station. A arranged between the bogies of a car support structure is lifted and pivoted by provided outside of the car engine means. The position of the wagon relative to the motor means here is precisely determined and must be adjusted via a centering device. The centering process and the associated maneuvering of the train lead to long loading and unloading times. A similar concept is in WO 93/18951 shown.

The EP 1 348 603 A1 . EP 0 463 283 such as CN 105 584 492 A show freight wagons with a pivotable about a central axis, drivable area. For the displacement of the respective surface-providing components lifting-swivel systems are provided, which are either integrated stationary in the track bed or indeed are part of the car, but must be supported by herabsenkbare supports on the tracks. In these systems, the train must be solved in total or static-dynamically interrupted in order to realize the loading and unloading. This is associated with a high amount of time.

The FR 1 141 612 A shows a freight car with a pivot platform arranged on a lifting platform. The means for lifting and pivoting are supported in the region of the carriage frame, which has a functional cutout into which the lifting platform can be lowered. The pivot point of the swivel platform is not centrally located, so that time-consuming maneuvers in the backward direction must be performed during loading and unloading.

The invention is concerned with the problem of creating a track-bound transport of at least a self-sufficient transport vehicle freight cars, with the transfer and removal of the transport vehicle is largely possible without stationary Umstellaktivitäten in the loading station and its optimum transport position with little effort to the specific Load compartment dimensions of a standardized tensile composite can be adjusted.

The invention solves this problem with a freight car with the features of claim 1. Further advantageous embodiments will become apparent from the claims 2 to 10.

In general, it can be assumed that special freight wagons are known for the track-bound transport of at least one self-sufficient transport vehicle. In this case, in particular, a displaceably held bridge part can be used as a usable usable area of the freight wagon, so that thus the load transporter can be transferred from road traffic to rail traffic and back.

An improved freight car for this track-bound transport is now provided with a bridge part, which is formed according to the invention as a base frame formed with a central functional cutout. This compact base frame is designed in the area of the functional section, which can be optimized in size, so that a "free space" is given and thus one - a movable one Effective area - forming support structure can be effectively integrated as an additional component in the system. The new "roll on roll off" freight wagon thus has a special multipart subassembly, so that previous solutions can be improved with this combined structure.

It is provided that by means of at least partially displaceable in the functional section in a lowered position of use support structure adapted at least one positionable on this transport vehicle to respective defined for rail transport dimensions of the usable transport space and thus the overall space utilization is improved. With this concept, it is achieved that the transport space available in terms of railway technology - with regard to transport costs - can not only be optimally utilized, but also maximally exploited, at least in the transverse and vertical directions. In addition, with the new component combination, it is possible to take loads of up to 80 tonnes with the base frame support structure system. This is possible when using a standard bogie with high speed approval - for example greater than 150 km / h.

It is further provided that the lowerable in the functional section of the base frame and liftable from this supporting structure by means of a variably adjustable actuator is continuously or stepped displaced, wherein the cooperating with the support structure actuator is formed by at least one integrable in the multi-part assembly hub-swing system , It is also provided that the hub-swivel system is supported in the region of the base frame.

Based on these - by moving the positioned on the support structure - transport vehicles provided for their handling design component is designed so that the loading and unloading process can be performed efficiently with a controllable component assembly and the corresponding service times are minimized.

During the loading process, the load transporter, which has in particular automatically moved onto the displaceable support structure, is moved in such a way that it can additionally be adapted to a rail-specific clearance profile during this loading phase. This means that even load transporters with varying loading volumes can be fixed and transported in a well-positioned position on the freight wagon. It is likewise provided that respective length dimensions of variably executable support structures can be adapted to a respective standard length of transport vehicles, so that maximum length utilization is possible. It is also conceivable that an optimal utilization of the length of the freight car is achieved for example by multi-part support structures.

The setting concept of the support structure provides that, in addition to the vertical displacement or adaptation to the transport space of the freight wagon, a construction is provided which permits an at least partially pivotable displacement of this new support structure. It is envisaged that the support structure in addition to the vertical displacement is at least partially pivotally held about a central vertical axis, as has already been realized in the prior art.

The extensive automation of this hub-swing system provides that this can be provided with a - the resting transport vehicle largely self-contained or solving from the transport position - locking device.

The structural optimization of the displaceable components of the freight wagon provides that, in particular, its support structure is designed as a support trough cooperating with respective connecting parts in the region of the base frame and ready to be prepared as a prefabricated individual part. This support trough can be positioned as a removable component by means of the above-described hub-pivot construction at least partially above and / or next to a track position. Here is a corresponding process of driving or stopping. In a subsequent support phase, the support trough which can be embodied as a removable component is transferred by means of a transfer unit into the driving position on the base frame. It is also conceivable that several support trays to be loaded one above the other in a rack above a rack o. The like. Are fixed.

The optimal design of the support trough provides that this is carried out substantially in one piece and provided in cross section with respective profiles so is that on the one hand for the underside attacking hub-pivot system an optimal support and fixing position is specified and on the other hand at the top of the support trough for the chassis of the truck defined lanes - at least for the range of rolling wheels - are specified.

According to the invention, the functional detail of the assembly in the region of the base frame is provided with at least one support strut which engages under the support structure at least in some areas.

This counter-support strut can be integrated in the manner of a center console extending in the direction of the longitudinal center plane into an overlying profiling of the support structure. This center console forms with low component costs a stiffening structure with which a sufficiently stable support is achieved for heavy transport vehicles for the above-described process of lifting and pivoting.

Preferably, the support structure for further stabilization, in particular during pivoting and / or driving, supported by an arrangement of rollers of a relatively elevated to the track level platform or the like ground. The rollers are in particular arranged at the end and on the underside of the center console, whereby a stable support of the support structure is achieved.

Another design variant in this area provides that the base frame in the area of the center console can be provided with a bottom plate. This is in addition to the central hub-pivot support with respective corner-mounted stroke guide rods, in particular stroke-guide spindles, equipped, so that a ground-parallel height guide is feasible. Such lifting guide rods, in particular lifting guide spindles, can also be arranged directly on the corner regions of the support structure.

In a preferred embodiment of the invention, the base plate is first lifted by the lifting guide rods, in particular lifting guide spindles, up to a level with a raised platform or the like ground relative to the track level. Thereafter, the center console and the support structure are raised slightly by means of the lifting-swivel system and then pivoted, the arrangement of rollers supporting the center support on the ground and thus stabilizing the pivoting movement.

An adapted to the optimization of the transport conditions further development of the freight wagon according to the invention provides that this is provided at least in the complex assembly of base frame and support structure with an overlying the resting transport vehicle at least partially covering shell construction. This envelope construction can form a substantially closed cover unit. This also executable in several parts cover can be connected to the frame of the freight car or the area of the bogies displaced, so that the system is partially covered.

In addition, it is provided that this cover unit can also be made in several parts, so that individually displaceable cover sections can be used in different areas of the freight car. In particular, it is provided that in the wagon body a usable for the driver of the truck transporter residence and / or service compartment is divided by means of a covering section.

From a synopsis of Fig. 1 and Fig. 10 the basic structure of the freight car 1 according to the invention for the carriage of at least one self-sufficient transport vehicle 2 on a respective rails 3, 4 having track system ( Fig. 4 ) clear. As a transport vehicle while a truck is shown with semi-trailer, in which case largely arbitrary structures of transport vehicles for receiving on the freight car 1 are conceivable.

It is known that goods wagons 1 may have a bridge part extending between the front bogie 5 and a rear bogie 6 and being displaceably held as a usable usable area 7. It is understood that the two bogies 5, 6 may be formed preferably symmetrical and component identical to the transverse axis of the freight car 1. With the roll on-roll-off systems designed in this way, it is possible that at least one load transporter 2 to be transferred from road traffic into rail traffic can drive onto or off the freight wagon, although the varying platform edges cause corresponding payload losses on the wagon superstructure.

The improvement according to the invention of this freight wagon system provides that the bridge part which is provided between the front and rear bogies 5, 6 and defines a subframe known per se is now designed as a base frame 8 provided with a central functional cutout F. This cooperates with at least one movable support surface 7 forming a support structure 9 as a multi-part assembly together. With this combination of components is achieved that by means of at least partially in a lowered position of use in the functional section F movable support structure 9, the at least one positionable on this transport vehicle 2 ( Fig. 10 ) to respective dimensions of the usable transport space defined for the web transport (circumferential line T, Fig. 11 ) can be adjusted. In addition to the known pivoting according to arrow S is now a vertical stroke according to arrow A and a vertical lowering according to arrow A 'integrated into the system.

The concept of the displaceable support structure 9 is advantageously geared to ensuring that a load transporter 2 accommodated on the goods wagon 1 (FIG. Fig. 11 ) in a driving plane E ( Fig. 6 . Figure 11 ) can drive onto the system, then the pivoting movement S is executable and then a lowering movement according to A '(travel) is executable so that the transport truck located in the transport T 2 ( Fig. 10 ) is integrated optimally at its access height ZH into the maximum height HG of the freight car 1. It is understood that while the length LG of the freight car 1 ( Fig. 10 ) and its width BG can also be utilized to the maximum.

To realize the above-described loading and unloading processes, the concept provides that the support structure 9, which can be lowered into the functional cutout F of the base frame 8 and can be raised therefrom, can be moved by means of a constructionally variably executable actuator (FIG. Fig. 4 to Fig. 9 ) can be relocated. In principle, it is conceivable that a stepless or stepped increase or decrease of the system components takes place by means of the actuator.

Based on this improved utilization of the novel wagon construct enabling stroke displacement A, A 'is provided that the support structure to be adapted thereto 9 also uses a well-known from the prior art pivotal movement according to arrow S for the loading process. For this purpose, it is provided that the support structure 9 is held pivotably in the region of the base frame 8, at least in one of its subregions (not shown in more detail). It is understood that the illustrated one-piece support structure 9 in particular about a central vertical vertical axis C is pivotable.

The design of the freight car 1 is directed to the application of a hub-swing system, wherein the co-operating with the support structure 9 actuator is provided as an integral part of this component combination. The hub-pivot system is supported only in the area of the base frame 8. In the area of the support structure 9, the lifting / swiveling system can then also be provided with a locking device (not shown) which automatically detects or releases the resting transport vehicle 2.

The constructive development of the inventive concept of the frame carrier combination having freight car 1 provides that the specific design of the support structure 9 is directed to a cooperating with respective connecting parts in the region of the base frame 8 and providable as a ready-made item support tray 12. This formed in the manner of a variably dimensionable and also executable multi-part charging tray support trough 12 can be moved with the above-described individual components of the hub-pivot system be that from the schematic diagrams according to Fig. 4 to Fig. 9 apparent operating positions are accessible.

It is also conceivable that a plurality of individual support trays (not shown) to be loaded one above the other or one behind the other in a cooperating with the base frame 8 frame (also not shown) can be set.

An optimal design of the support trough 12 - from the viewpoint of a rigid and highly resilient construction - provides that the substantially one-piece support trough 12 in cross-section with respective profiles 13, 13 '( Fig. 4 ).

For the preferred embodiment of the freight car 1 with the system-integrated support of the movable components is provided that the base frame 8 in the region of the functional section F, the support structure 9 at least partially under cross and arranged in the manner of a center console 14 Gegenhaltestrebe ( Fig. 3 ) having. This center console 14 is designed so that it is overlapped by a central profiling 15 of the support structure 9 and thus the required space can be minimized.

A further embodiment of this stable support system provides that the base frame 8 can also be provided with an additional base plate 16 in the region of the center console 14. In the area of this bottom plate 16 is expediently in the Fig. 3a shown lifting guide 17 in the form of lifting guide rods, in particular lifting guide spindles, o. The like. Driven elements provided. In this case, this lifting system is provided in the respective corner regions of the bottom plate 16. It is also conceivable that such a lifting system is arranged on the support structure 9 (not shown) in order to stabilize the lifting movements A, A '. In any case, a ground-parallel stroke displacement of the rigid bottom plate 16 can take place. The structural parts of this system integrated structure are also from the respective sectional views in Fig. 4 to 9 can be seen, in which not all of the reference numerals are completely given for clarity.

A further embodiment of the above-described freight car 1 for improving the transport conditions is in 10 and 11 illustrated, wherein the freight car 1 is provided at least in the region of the assembly of the base frame 8 and support structure 9 with an overlying the resting transport vehicle 2 at least partially covering Hull construction. This envelope construction K thereby forms a substantially closed cover unit, which could possibly also be displaced from the illustrated closed position. From the side views in 10 and 11 It is clear that the cover unit K has a plurality of cover sections with a front part and a rear part. These cover sections can be embodied such that a residence and / or service room AR is created for a user intended to operate the transport vehicle 2, and thus rapid implementation of the vehicle 2 can be achieved when a loading station is reached.
