[0002] Overhead contact line system with fixing device and method for reducing a lateral contact wire deviation of an overhead contact line system by means of a fixing device

[0003] The invention relates to an overhead line system with at least one fixing device and a method for reducing a lateral contact wire deviation of an overhead line system by means of at least one fixing device.

[0004] In known overhead line systems for a traffic system, such as railways, the contact wire is arranged above a track intended for the vehicles of the traffic system, and is connected to supporting devices of the overhead line system, for example masts fixed in the ground or, preferably in inner-city areas, also structures such as houses, noise barriers or similar. While in motion, the vehicles are in sliding contact with the contact wire in order to draw the necessary traction energy from the contact wire. The contact wire is usually laid in a zigzag pattern in order to achieve even wear on the contact surface of the contact strip(s). The maximum possible longitudinal span between the supporting devices, for example masts, of the overhead line system is crucial for the installation costs and also for the functionality of the overhead line system during operation.

[0005] The maximum possible longitudinal span, i.e. the maximum possible mast spacing, is determined by the usable contact rail width of a pantograph of a vehicle in question, the maximum wind downforce of the overhead line and the route geometry. The maximum possible longitudinal span is therefore determined as a sum of the maximum permissible lateral contact wire deviation from a route center, e.g. the track center. For frequently occurring interoperable operation, i.e. for vehicles with different usable contact rail widths, the smallest contact rail width determines the lateral permissible contact wire deviation from the route center and thus the maximum possible mast spacing or the maximum possible longitudinal span.

[0006] If the maximum assumed wind force is increased or if a switch to a smaller contact strip width is made, e.g., by installing a new vehicle, the permissible contact wire deviation from the centerline is reduced. To achieve the reduced contact wire deviation, new contact line masts with different spacing or a new overhead line system with reduced longitudinal spans might have to be erected. This is economically unviable and therefore generally not done.

[0007] EP 3 676 125 A1 discloses an advantageous solution for free sections of tracks with overhead contact line systems while maintaining the existing mast spacing, by means of which the laterally permissible contact wire deviation from the track centre can be reduced in an existing overhead line with re-tensioned contact wire.

[0008] In addition to open track sections, there are many other sections on existing lines, particularly in stations, where the overhead line is not attached to individual pylons, but to so-called cross-supporting structures. For interoperable operation, a reduction in the permissible lateral deviation of the overhead wire from the track center is generally necessary for interoperable operation, using an existing cross-supporting structure with a re-tensioned overhead wire of an existing overhead line system. However, this is usually not readily possible and is therefore frequently omitted for economic reasons.

[0009] The invention is based on the object of specifying an overhead contact line system with a fixing device and a method for reducing a lateral contact wire deviation of an overhead contact line system by means of a fixing device, with which reductions in the laterally permissible contact wire deviation from the track center can be easily realized, especially in the area of ​​transverse support structures.

[0010] The problem is solved by the features of independent patent claims 1 and 12. Further developments and refinements of the invention are found in the features of the dependent patent claims.

[0011] For this purpose, the overhead line system according to the invention has at least one fixing device which fixes the contact wire at least in the region of the at least one transverse support structure substantially transversely to the longitudinal direction, wherein the fixing device is connected at least by means of a suspension point to the at least one supporting cable, by means of at least two spaced-apart transverse connection points to the lower transverse cable of the transverse support structure and by means of at least two spaced-apart longitudinal connection points to the contact wire.

[0012] The solution according to the invention has the advantage that, in a simple manner, by connecting the supporting cable, the cross-supporting structure and the contact wire to one another, mutual or opposing movements are restricted and thus a reduction in the lateral deviations of the contact wire from the center of the track is achieved, particularly in the area of ​​cross-supporting structures, without the construction of additional support devices being necessary. The invention is therefore also very well suited to conversions, since existing overhead line systems can also be easily converted using the invention in order to achieve a significant, reduced lateral deviation of the contact wire from the center of the track. In this way, the costs for a new overhead line system can be saved or the costs for the conversion of an existing overhead line system can be significantly reduced.The overhead line design adapted according to the invention therefore makes it easy to use narrower pantograph widths, for example in new vehicles, particularly in the area of ​​transverse support structures. According to a preferred embodiment of the invention, the at least one fixing device of the overhead line system comprises at least one suspension, at least one frame, and at least two side supports.

[0013] Particularly preferably, the at least one suspension of the fixing device is connected to the at least one frame of the fixing device and by means of the suspension point to the supporting cable and each of the at least two side holders of the fixing device is each connected to the frame of the fixing device and by means of one of the at least two longitudinal connection points to the contact wire, wherein the frame of the fixing device is connected to the lower cross cable of the cross support structure by means of the at least two cross connection points.

[0014] The fixing device thus consists of simple or commercially available components, which in turn ensure an equally flexible and effective fixing device with regard to reducing lateral contact wire deviations from the center of the track, so that both the construction and the cost expenditure are manageable and the solution according to the invention is therefore comparatively inexpensive.

[0015] Preferably, the at least one frame of the fixing device has a plurality of rod-shaped connecting parts, wherein two connecting parts are directly connected to one another.

[0016] The frame is therefore flexible and easy to manufacture and can be individually adapted to almost any geometric shape according to local requirements. As a result, it has a corresponding number of rod-shaped connecting parts. The rod-shaped connecting parts, for example hollow or solid tubes, also make the frame stable, particularly against the effects of the weather, such as wind and storms. The frame is preferably designed to be closed, but can also be designed to be open if necessary. Depending on requirements, the stability of the frame can be further increased by welding the rod-shaped connecting parts together, which is particularly effective with a closed frame design.

[0017] Particularly preferably, the interconnected, rod-shaped connecting parts of the at least one frame of the fixing device are connected to one another in an articulated manner. This makes the frame more mobile while simultaneously maintaining the desired or necessary stability, whereby mutual movements of the individual components of the fixing device connected to the frame, for example due to vehicle traffic and / or environmental or weather influences, etc., can advantageously be compensated for flexibly and automatically, at least to a large extent.

[0018] According to a further preferred development of the invention, the at least one suspension of the fixing device has a plurality of cable-shaped connecting parts, wherein the cable-shaped connecting parts are bundled at one end in the suspension point and the fixing device is fastened to the supporting cable at the suspension point by means of the cable-shaped connecting parts, and wherein the cable-shaped connecting parts are connected at the other end, at a respective connection point, to at least one rod-shaped connecting part of the at least one frame of the fixing device. The fastening or integration of the fixing device on or in existing overhead line systems is thereby particularly easy.

[0019] The use of rope-shaped connecting parts, for example, movable yet stable ropes made of suitable conductive or non-conductive materials, as suspension for connection to the frame also ensures the necessary mobility of the fixing device. The number of rope-shaped connecting parts required for suspending the fixing device is fundamentally independent of the number of rod-shaped connecting parts used to form the frame of the fixing device and is essentially determined by the requirements of the local conditions where one or more fixing units are used.According to a further particularly preferred development of the invention, the at least one frame of the fixing device has three rod-shaped connecting parts and is substantially triangular in shape, wherein each of the three corner points of the frame is designed as a connecting point for connection to one of the rope-shaped connecting parts of the suspension of the fixing device.

[0020] Preferably, the at least one suspension of the fixing device has three rope-shaped connecting parts, wherein the fixing device is fastened to the supporting cable at the suspension point by means of the three rope-shaped connecting parts and each of the three rope-shaped connecting parts of the suspension connects the supporting cable to one of the three connection points of the frame of the fixing device.

[0021] Thus, only three rod-shaped and rope-shaped connecting parts are required, and at the same time, two connecting parts of the frame are each connected to a rope-shaped connecting part of the suspension by means of a corner or connection point.

[0022] As a result, the fixing device can be designed to be particularly stable and flexible as well as material- and thus cost-saving due to the simple geometric basic shape of the frame, whereby a significant reduction in the lateral contact wire deviation from the center of the track can be achieved particularly easily and effectively.

[0023] According to a particularly preferred embodiment of the invention, one of the three corner points of the frame is connected to the lower cross cable of the cross support structure as one of the at least two cross connection points, and the rod-shaped connecting part of the frame opposite this corner point is connected approximately centrally to the lower cross cable as the second of the at least two cross connection points of the cross support structure, wherein the contact wire crosses the lower cross cable between the at least two cross connection points below the lower cross cable of the cross support structure. The fastening of the fixing device to the cross support structure, in particular to the lower cross cable, the so-called lower guide cable, of the cross support structure is thus particularly simple and quick, thereby effectively supporting and further improving a reduction in the lateral contact wire deviation from the center of the track.

[0024] According to a further preferred embodiment of the invention, each of the two corner points of the rod-shaped connecting part of the frame, which is opposite the corner point of the frame which is connected to the lower cross cable as one of the at least two cross connection points, is connected to one end of the at least two side holders of the fixing device and each of the at least two side holders of the fixing device is connected to the other end by means of one of the at least two longitudinal connection points to the contact wire.

[0025] On the one hand, side supports are common and readily available components and, moreover, are a long-standing, proven means of achieving fixation transverse to the longitudinal direction of the contact wire. Since side supports in the standard design are movable both vertically and longitudinally along the contact wire, they complement the inventive properties of the fixation device in a highly advantageous manner in combination with the other components, the frame and suspension.

[0026] Particularly preferably, the center of gravity of the fixing device is located approximately vertically below the suspension point on the supporting cable. This ensures self-centering and, consequently, correspondingly advantageous mechanical properties with regard to stability and mobility of the fixing device.

[0027] A further aspect of the present invention relates to a method for reducing a lateral contact wire deviation of an overhead line system, which has at least one contact wire, a supporting cable and a plurality of hangers, by means of which the at least one contact wire is suspended from the at least one supporting cable, wherein the at least one contact wire and the at least one supporting cable run substantially in the longitudinal direction of a track, as well as a plurality of supporting devices connected to a floor, and at least one transverse supporting structure, wherein the at least one transverse supporting structure comprises at least one transverse supporting cable and a lower transverse cable, and wherein the at least one transverse supporting structure is connected to at least one supporting device transversely to the track running in the longitudinal direction on one side of the track, wherein at least one fixing device is arranged in such a way thatthat the contact wire is fixed at least in the region of the at least one transverse support structure substantially transversely to the longitudinal direction and wherein the fixing device is connected at least by means of a suspension point to the at least one supporting cable, by means of at least two spaced-apart transverse connection points to the lower transverse cable of the transverse support structure and by means of at least two spaced-apart longitudinal connection points to the contact wire.

[0028] The previously described embodiments of the invention and in particular their advantages are transferable to the said method and therefore also apply to the said method.

[0029] Preferred embodiments of the invention are explained in more detail below with reference to the drawings. They show:

[0030] Fig. 1 A schematic representation of an embodiment of an overhead line system according to the invention with a fixing device and

[0031] Fig. 2 is a schematic representation of the embodiment of an overhead line system according to the invention with a fixing device from Fig. 1 in a perspective view from above.

[0032] In Figures 1 and 2, identical parts are designated by the same reference numerals. The embodiments may differ from one another. The corresponding support structures, such as masts, buildings, etc., that hold the transverse support structure 10 laterally, as well as the track itself, are not shown in either figure for reasons of clarity.

[0033] Fig. 1 shows a schematic representation of an embodiment of an overhead line system 1 according to the invention with a fixing device 20 in a side view looking diagonally from below upwards. The overhead line system 1, shown here in detail, for a track running in a longitudinal direction consists of a contact wire 2, a supporting cable 3 and a plurality of hangers 4, by means of which the contact wire 2 is suspended from the supporting cable 3. The contact wire 2 and supporting cable 3 run essentially along the track, not shown here. The overhead line system 1 according to Figure 1 further has a cross-supporting structure 10 which comprises a cross-supporting cable 11, an upper cross cable 13, which is also referred to as the upper guide cable, and a lower cross cable 12, which is also referred to as the lower guide cable.The transverse support structure 10 runs transversely to the longitudinally extending route and is - shown here only partially for reasons of clarity - connected on each side of the route to at least one support device, for example to individual masts, buildings, etc. connected to a floor.

[0034] Figure 1 also shows a fixing device 20 according to the invention as a further component of the overhead line system 1.

[0035] The fixing device 20 consists of a suspension 23, a frame 25, and two side supports 22 and is connected to the support cable 3 at the suspension point 15, or suspended there. By means of an insulator 5, one end of which is also connected to the support cable 3 at the suspension point 15, the support cable 2 and thus also the fixing device 20 are electrically insulated from at least the upper cross cable 13, which is also referred to as the upper guide cable, of the cross support structure 10.

[0036] According to the embodiment shown in Figure 1, the frame 25 of the fixing device 20 is essentially triangular in shape and here consists of three rod-shaped connecting parts 26 which are each articulated to one another at the three corners of the triangle. The three rod-shaped connecting parts 26 are hollow or solid profiles, for example tubular, so that the frame 25 is both correspondingly stable, in particular with regard to the effects of the weather, for example wind and storms, and at the same time correspondingly movable thanks to the articulated connections. As a result, mutual movements of the components of the fixing device 20 or of the overhead line system 1 which are directly and / or indirectly connected to the frame 25, for example due to vehicle traffic and / or the aforementioned environmental or weather influences, etc., can advantageously be compensated for flexibly and automatically, at least for the most part.The frame 25 is, as shown in Figure 1, advantageously a closed triangle for stability reasons, but can also be designed open if necessary. Furthermore, other geometric shapes for the frame 25, such as rectangles, etc., are of course also possible without restriction, depending on requirements.

[0037] The suspension 23, by means of which the fixing device 20 is suspended at the suspension point 15 on the supporting cable 3, consists according to the embodiment shown in Figure 1 of three cable-shaped connecting parts 24, which converge in a bundle on one side at the suspension point 15 and are connected to the frame 25 on the other side.

[0038] As shown in Figure 1, each of the three corner points of the frame 25 is simultaneously a connection point 17 which is connected to one of the three rope-shaped connecting parts 24 of the suspension 23 of the fixing device 20, so that the supporting cable 3 is indirectly connected to one of the three connection points 17 of the frame 25 of the fixing device 20 by means of the three rope-shaped connecting parts 24.

[0039] By using rope-shaped connecting parts 24, for example movable and at the same time stable ropes made of suitable conductive or non-conductive materials, as suspension 23 for connection to the frame 25, the necessary mobility or flexibility of the fixing device 20 is further improved.

[0040] By means of a respective corner or connection point 17, two rod-shaped connecting parts 26 of the frame 25 are connected to one another in each case with a respective rope-shaped connecting part 24 of the suspension 23, whereby the fixing device 20, due to the simple geometric basic shape of the frame 25 in conjunction with the movable suspension 23, is at the same time particularly stable and flexible as well as material- and thus cost-saving and consequently a significant reduction in the lateral contact wire deviation from the center of the track can be achieved particularly easily and effectively.

[0041] As further shown in Figure 1, one of the three corner or connection points 17 of the frame 25 is simultaneously one of two cross-connection points 14 with which the frame 25 is directly connected to the lower cross cable 12 of the cross-supporting structure 10. The second cross-connection point 14 with which the frame 25 is directly connected to the lower cross cable 12 of the cross-supporting structure 10 is located approximately centrally on the rod-shaped connecting part 26, which is opposite the aforementioned corner point 17, the frame 25 being connected to the lower cross cable 12 of the cross-supporting structure 10 in such a way that the contact wire 2 crosses the lower cross cable 12 between the two cross-connection points 14 without touching below the frame 25 and the lower cross cable 12.On the respective outer side of the frame 25, outside the two cross-connection points 14, the lower guide cable 12 has a further insulator 5, so that the fixing device 20 is also electrically insulated from the outside at this point. The two cross-connection points 14 of the lower cross-cable 12 of the cross-supporting structure 10 are thus the two guide points of the overhead line in the transverse direction, in order to be able to continue using the existing overhead line system 1 if the laterally permissible contact wire deviation from the track center is changed to a smaller value.

[0042] Each of the two corner points 17 of the above-mentioned rod-shaped connecting part 26 of the frame 25 is additionally connected to one end of the two lateral supports 22 of the fixing device 20, and each of the two lateral supports 22 of the fixing device 20 is in turn connected to the other end of the contact wire 2 by means of one of two longitudinal connection points 16. The two lateral supports 22 and thus the two respective longitudinal connection points 16 are attached to the contact wire 2 at a suitable distance from one another in the direction of the route or track direction, or are connected to the contact wire 2, depending on the requirements of the local conditions.

[0043] The lateral supports 22 are, on the one hand, conventional and readily available components and, moreover, are a long-proven means of achieving fixation transverse to the longitudinal direction of the contact wire. As in the present case, the lateral supports 22 are movable in the conventional design both vertically and longitudinally of the contact wire 2 and thus, in combination with the other components of the frame 25 and suspension 23, extremely advantageously complete the inventive properties of the fixation device 20.

[0044] According to the invention, the fixing device 20 thus connects the supporting cable 3 by means of the suspension point 15, the cross-supporting structure 10 by means of the two spaced-apart transverse connection points 14 and the contact wire 4 to one another by means of the two spaced-apart longitudinal connection points 16 and consequently restricts mutual or opposing movements of the individual components of the overhead line system 1 among one another at this point. At the same time, the distance to the next guide point along the track (longitudinal span of the contact wire) is reduced by the distance between the two guide points 16. This significantly reduces the lateral deviations of the contact wire from the center of the track in the area of ​​the cross-supporting structure 10 without the need to build additional support devices. Overhead lines with re-tensioned contact wires can be easily re-tensioned or extended using the invention using the existing cross-supporting structures 10.be converted, so that the invention is also very well applicable for conversions. Consequently, other areas of the overhead line system 1 can also be easily converted using the invention in order to achieve a significant, reduced lateral contact wire deviation from the track center there as well. The invention thus also easily enables the use of narrower pantograph widths, for example in new vehicles, particularly in the area of ​​transverse support structures.

[0045] Fig. 2 shows a schematic representation of the embodiment of an overhead line system 1 according to the invention with the fixing device 20 from Fig. 1, viewed from above. The individual distances between the components of the overhead line system 1 and the fixing device 20, and the respective dimensions, are not shown to scale to clarify the design.

[0046] Figure 2 clearly shows that the center of gravity of the fixing device 20 is located approximately vertically below the suspension point 15 on the supporting cable 3, which supports the contact wire 2 by means of the hangers 4, and also exaggeratedly shown here that, due to the design, the center of gravity of the fixing device 20 and thus also the supporting cable 3 in the area of ​​the fixing device 20 is located away from the contact wire 2 with respect to the longitudinal direction of the travel route and is thus slightly offset laterally above the contact wire 2.

[0047] The two cross connection points 14 as guide points of the contact line in the transverse direction are each arranged on different, opposite sides of the contact wire 2 on the lower cross cable 12, which runs between the two side holders 22 and thus the longitudinal connection points 16 transversely to the contact wire 2.

[0048] Figure 2 also shows the three rope-shaped connecting parts 24 of the suspension 23, which run from the suspension point 15 to the three corner or connecting points 17 of the triangular frame 25, consisting of the three rod-shaped connecting parts 26 of the fixing device 20, and thus connect them to one another.

[0049] It can also be seen that one of the three corner or connection points 17 of the frame 25 coincides with one of the two cross-connection points 14, that the second cross-connection point 14 is located on the opposite side of the contact wire 2 approximately in the middle of the rod-shaped connecting part 26, which is opposite the aforementioned corner point 17, and that the two side holders 22, starting from the two connection points 17 of this rod-shaped connecting part 26, are connected to the longitudinal connection points 16 and thus to the contact wire 2 and have a suitable distance from one another in the direction of the route or track direction, depending on the requirements of the local conditions.

[0050] Of course, the solution according to the invention is not limited to the embodiments according to Figures 1 and 2, but implicitly also includes all other possible deviations from the embodiments shown in Figures 1 and 2.

[0051] Regardless of the grammatical gender of a particular term, persons with male, female or other gender identity are included.
