Deflection device and arrangement for the protection of a track layout from environmental influences

Description

[0001] The invention relates to a deflector device for protecting a track arrangement from environmental influences such as wind, snow or sand, as well as to an arrangement comprising a track arrangement and a deflector device according to the invention.

[0002] Deflector devices for protecting a track from environmental influences such as wind, snow or sand are known and published in various designs.

[0003] EP 1 740 772 B1, for example, discloses a wind and snow deflector in which two flexible shields protrude in opposite directions from a fastening part, wherein the two shields are formed from groups of bristles. The downwardly projecting bristles of one shield can flexibly deform and thus create a seal against an uneven surface. Such arrangements have long been known as so-called brush seals. The other shield projects upwards with its bristles, thus forming a flexible wind deflector. Brush-shaped wind deflector strips of this type have also long been known.

[0004] In practice, it has now been shown that it can be advantageous not to design the lateral deflectors to be completely sealed, but rather to allow a portion of the airflow, i.e., the wind, to pass through. This improves the flow conditions in such a way that less wind, or less wind-carried snow or sand, hits the track arrangement. A targeted passage of a partial volume flow is not mentioned in EP 1 740 772 B1.

[0005] EP 1 740 772 B1 also discloses an upwardly extending wind and snow protection device formed by a slat, in particular a plurality of membrane segments.

[0006] Such membrane segments are not suitable for allowing a partial volume flow of wind to pass through. Furthermore, slotted bands tend to tear further under mechanical stress, which impairs the effectiveness of these deflectors over time.

[0007] The object of the invention is to overcome the disadvantages of the prior art. In particular, the object of the invention is to create a deflector device that enables efficient, aerodynamically optimized deflection over long service lives.

[0008] The object of the invention is achieved in particular by the features of the independent patent claims.

[0009] The invention relates in particular to a deflector device for protecting a track arrangement and in particular a switch from environmental influences, such as wind, snow or sand, comprising an elongated retaining strip running along a longitudinal direction for attachment to the side next to the track arrangement, wherein a flexible floor apron and a flexible wind shield are attached to the retaining strip, wherein the floor apron, following the elongated contour of the retaining strip, projects from the retaining strip towards the ground, wherein the wind shield, following the elongated contour of the retaining strip, projects upwards from the retaining strip.

[0010] According to the invention, main incisions are provided in the floor apron, each of which extends in a slit-like manner from the outer edge of the floor apron into a functional opening with a rounded shape.

[0011] If necessary, it is provided that secondary incisions are provided in the floor apron, which each extend in a slit-like manner from the outer edge of the floor apron into a functional opening with a rounded shape, but are interrupted in an area between the outer edge and the functional opening.

[0012] If necessary, the floor skirt may include several flexible floor slats to adapt the floor skirt to an uneven surface.

[0013] Where appropriate, the floor slats are formed by the main cuts provided in the floor apron and, where appropriate, by the secondary cuts provided in the floor apron.

[0014] Where appropriate, the windscreen is provided with main cuts which extend in a slit-like manner from the outer edge of the windscreen to a functional opening with a rounded shape

[0015] Where appropriate, the wind shield shall be continuous and uninterrupted.

[0016] If necessary, it is provided that secondary incisions are provided in the windscreen, each of which extends in a slit-like manner from the outer edge of the windscreen into a functional opening with a rounded shape, but is interrupted in an area between the outer edge and the functional opening.

[0017] Where appropriate, the windscreen is provided with several flexible wind vanes and the wind vanes are formed by the main incisions provided in the windscreen and, where appropriate, by the secondary incisions provided in the windscreen.

[0018] Where appropriate, it is provided that the floor skirt and the wind shield comprise a single band-shaped base body made of an elastic material, that the band-shaped base body is connected to the retaining strip in its central region along the longitudinal direction, and that the base body protrudes from the retaining strip on both sides transversely to its longitudinal direction.

[0019] If appropriate, it is provided that the floor skirt and the wind shield each comprise a band-shaped base body made of an elastic material, that the two band-shaped base bodies are connected to the retaining strip along their longitudinal direction, and that the base bodies each protrude from the retaining strip on both sides transversely to their longitudinal directions.

[0020] Where appropriate, the functional openings are designed as through openings with a rounded or circular cross-section.

[0021] Where appropriate, it is provided that the functional openings of the floor skirt and / or the windscreen have a free cross-section of between 0.5 cm 2< and 5 cm 2< , in particular between 0.5 cm 2< and 2 cm 2< .

[0022] Optionally, it is provided that the floor slats are strip-shaped and have a width measured along the longitudinal direction of between 1 cm and 5 cm, in particular between 2 cm and 4 cm, and / or that the floor slats are strip-shaped and have a length measured transversely to the longitudinal direction of between 5 cm and 25 cm, in particular between 4 cm and 15 cm.

[0023] Optionally, it is provided that the wind slats are strip-shaped and have a width measured along the longitudinal direction of between 5 cm and 20 cm, in particular between 8 cm and 12 cm, and / or that the wind slats are strip-shaped and have a length measured transversely to the longitudinal direction of between 5 cm and 15 cm, in particular between 5 cm and 10 cm.

[0024] Where appropriate, the wind slats and / or the floor slats shall have a smaller width measured along the longitudinal direction in the areas between the functional openings than in the areas between the slots.

[0025] Where appropriate, it is provided that the incisions, in particular the main incisions and / or the secondary incisions, have a free width measured along the longitudinal direction which is smaller than the free width of the functional openings measured along the longitudinal direction and in particular have a free width measured along the longitudinal direction of 0 cm to 1 cm.

[0026] Where appropriate, it is provided that the wind slats and / or the floor slats and / or the base body(s) are made of a UV-resistant elastomer, such as in particular EPDM or soft PVC, and where appropriate with a reinforcing structure.

[0027] Where appropriate, it is provided that the wind slats and / or the floor slats and / or the base body(s) are formed from a strip with a thickness of 0.2 cm to 0.5 cm and in particular of 0.3 cm.

[0028] If appropriate, it is provided that the windshield and / or the floor apron are designed in multiple layers and in particular have two or more base bodies running parallel to one another, wherein one of the base bodies has a greater rigidity than the parallel base body in order to increase the strength of the windshield and / or the floor apron.

[0029] Where appropriate, the base body of the windscreen is provided with at least one reinforcing bead running along the longitudinal direction.

[0030] Optionally, the invention relates to an arrangement comprising a track arrangement with at least two rails which are connected to one another via superstructure components, such as railway sleepers, and are supported on the track substructure, in particular on the subsurface.

[0031] If appropriate, it is provided that a deflector device according to one of the preceding claims is provided laterally next to the outer side of at least one rail and following the course of the rail.

[0032] If necessary, a holding device is provided via which the holding bar is connected to the track arrangement.

[0033] Where appropriate, the windscreen shall extend to the level of the rail head, or the windscreen shall project upwards above the rail head, and in particular the windscreen shall project upwards above the level of the rail head by 1 cm to 5 cm, preferably by 2 cm.

[0034] If necessary, the gap between the retaining strip and the underlying surface is covered by the flexibly deformed floor skirt.

[0035] If appropriate, it is provided that a deflector device according to the invention is provided on both sides, laterally next to the outer sides of the rails and following the course of the rails, and that the rails and in particular the switch are arranged between the two deflector devices.

[0036] Where appropriate, it is provided that the floor skirt and / or the wind shield is or are connected to the track arrangement via a quick-release fastener, in particular via a fastener that can be operated without tools.

[0037] Where appropriate, provision is made for at least one windscreen running transversely to the track layout, which runs in particular between two rails of a track arrangement and acts as a wind deflector against air movements running along the track layout.

[0038] According to the invention, a floor skirt is provided that extends from a holding part designed as a retaining strip toward the floor. This flexible floor skirt has several notches, in particular so-called main notches, each of which extends in a slit-like manner from the outer edge of the floor skirt into a functional opening.

[0039] The functional openings each have a rounded shape and serve - as their primary function - as a passage opening for the passage of a partial air flow.

[0040] Furthermore, the rounded shape of the functional opening acts synergistically—as a second function—to counteract the tendency of a slotted floor skirt to tear. Narrow slots or cuts tend to tear further under mechanical stress. By terminating the cuts or cuts in a rounded functional opening, this tendency is significantly reduced. By providing several parallel main cuts, each of which preferably leads into a functional opening, floor slats are formed. These floor slats can adapt to an uneven subsurface or surface essentially independently of one another.

[0041] Furthermore, the functional openings have a greater free width than the notches or grooves that lead into them. As a result, the strip-shaped lamellae defined by the notches or grooves are also wider in the area of ​​the notches or grooves than in the area between the functional openings. This creates a kind of joint between the functional openings, again synergistically—as a third function.

[0042] A further advantage is that, due to its special design, the deflector device according to the invention is less prone to soiling than conventional deflector devices, which are designed, for example, as brushes. Furthermore, the deflector device according to the invention preferably also reduces the amount of gravel flying on gravel substructures.

[0043] In addition, it has been shown in practice that the special design of the deflector device according to the invention can also reduce rodent bites on the switches' lines.

[0044] In addition to the main cuts, additional cuts, so-called secondary cuts, may be provided. These secondary cuts also lead to a functional opening, but may be interrupted in an area between the outer edge and the functional opening, so that two strip-shaped slats separated by a secondary cut are or remain connected in this area. These secondary cuts can further improve and control the flexibility of the floor skirt. In particular, the ends of the slats located between the main cuts and the secondary cuts are free and can therefore adapt to an uneven surface.

[0045] The upwardly facing flexible windshield can also have main cutouts and, if appropriate, secondary cutouts similar to the cutouts in the floor skirt. Preferably, the cutouts of the windshield are spaced further apart along the longitudinal extent or longitudinal direction than the cutouts in the floor skirt, thus making the windshield's wind vanes wider than the floor vanes of the floor skirt.

[0046] Such a deflector device is preferably arranged laterally next to a track arrangement, in particular next to a switch. This protection allows moving parts of the switch to be better protected from environmental influences. In particular, the deflection of wind and snow can also reduce the energy required to heat a switch.

[0047] According to a preferred embodiment, deflector devices according to the invention are provided on both sides of the track arrangement, in particular on both sides of the switch.

[0048] The base skirt of the deflector device extends toward the surface formed, for example, by parts of the track substructure and superstructure, in particular by railway sleepers and ballast. The flexible windshield extends upwards, at least to the level of the railhead, preferably above the railhead, to deflect the wind.

[0049] The functional openings are preferably arranged approximately in the central region of the deflector device, for example in the vicinity of the holding part, which is designed in particular as a holding strip.

[0050] Where appropriate, the floor skirt and windshield may each comprise their own base body. These two base bodies may have different stiffnesses, so the floor skirt and windshield also have different stiffnesses.

[0051] If necessary, it is provided that the wind shield and / or the floor skirt are designed in multiple layers and in particular have two or more base bodies running parallel to one another.

[0052] Optionally, the retaining part for holding the windshield and / or the floor skirt is designed as a retaining strip. Preferably, the windshield and / or the floor skirt are connected to the retaining part, in particular to the retaining strip, via a clamping part.

[0053] In all embodiments, the incisions can be slit-shaped or groove-shaped and have a free width along the longitudinal direction of a few millimeters, or preferably be essentially closed. With closed incisions, the two adjacent slats directly abut one another, at least in sections. However, a free space is preferably maintained in the area of ​​the functional opening. As soon as adjacent slats are bent open to different degrees, openings are also formed, which, however, are essentially open along the longitudinal direction.

[0054] The invention will be further described below with reference to schematically illustrated embodiments of the invention.

[0055] The Figures 1a , 1b and 1c show three different schematic views of an arrangement.

[0056] The Figures 2a, 2b and 2cshow three schematic sectional views of details of three different embodiments.

[0057] Unless otherwise stated, the reference numerals correspond to the following components: track arrangement 1, retaining strip 2, floor skirt 3, wind shield 4, substrate 5, main cut 6, outer edge 7, functional opening 8, secondary cut 9, floor slat 10, surface 11, wind slat 12, base body 13, longitudinal direction 14, rail 15, railway sleeper 16, track substructure 17, outer side (of the rail) 18, retaining device 19, rail head 20.

[0058] The Figures 1a , 1b and 1c show different schematic views of an embodiment of a deflector device according to the invention, which together with a track arrangement 1 forms an arrangement according to the invention. Figure 1a shows a schematic side view from the outside, wherein parts of the track arrangement 1, such as in particular the rail 15, are covered by the deflector device. Figure 1bshows a schematic view or a sectional view, wherein the viewing direction runs essentially along the longitudinal direction 14. Figure 1c shows a schematic view from above.

[0059] The arrangement comprises a track arrangement 1 comprising at least one rail 15 and at least one railway sleeper 16. In particular, the track arrangement 1 comprises two rails 15 and a plurality of railway sleepers 16. In the present embodiment, the track substructure 17 is designed as a ballast bed, which, depending on the definition, also forms the subgrade 5.

[0060] A deflector device extends at a distance from the outer side 18 of the rail 15, in particular along the longitudinal direction 14. The deflector device is connected to the track arrangement 1 via a holding device 19. In particular, a holding device 19 can be arranged in the area of ​​one or more railway sleepers 16.

[0061] The deflector device comprises at least one holding part, which in the present embodiment is designed as a holding strip 2 running along the longitudinal direction 14. A floor apron 3 and a wind shield 4 are attached to the holding strip 2. The floor apron 3 extends from the holding strip 2 towards the surface 11. In the present embodiment, the surface 11 is formed alternately by the railway sleepers 16 and the track substructure 17, in particular the ballast bed. The floor apron 3 rests on the uneven surface 11 and is adapted in shape to the shape of the uneven surface 11. This adaptation allows coverage to be achieved to the desired extent. In order to achieve improved adaptability of the floor apron 3 to the uneven surface 11, the floor apron 3 has a plurality of incisions, in particular a plurality of main incisions 6.These main incisions 6 each extend from the outer edge 7 of the floor apron 3 into a functional opening 8 of the floor apron 3.

[0062] The incisions, in particular the main incisions 6, delimit or form floor slats 10 which are in particular strip-shaped.

[0063] According to this embodiment, in addition to the main incisions 6, several secondary incisions 9 are also provided. These secondary incisions 9 also extend from the outer edge 7 of the floor skirt 3 into a functional opening 8, with the secondary incisions 9 being interrupted in a region between the functional openings 8 and the outer edge 7. This allows two adjacent floor slats 10 to be connected to each other in their central region.

[0064] The functional openings 8 have a rounded shape and are designed as through-openings in the floor apron 3. In particular, the functional openings 8 have a round shape in the present embodiment.

[0065] This rounded shape prevents the cuts from tearing further under mechanical stress. Furthermore, the functional openings form eight holes through which air, particularly a partial volume flow of wind, can pass.

[0066] Furthermore, the functional openings 8 have a larger free width along the longitudinal direction 14 than the notches. As a result, the floor slats 10 delimited by the notches have a smaller width, measured along the longitudinal direction 14, in the area between the functional openings 8 than in the area between the notches. As a result, the functional openings 8 form a joint.

[0067] According to the present embodiment, the windshield 4 also has a plurality of wind vanes 12, which are defined or formed by incisions in the windshield 4. In particular, a plurality of main incisions 6 are provided, each extending from the outer edge 7 of the windshield 4 to the functional opening 8 of the windshield 4.

[0068] Furthermore, the windshield 4 according to the present embodiment comprises secondary incisions 9 which extend from the outer edge 7 of the windshield 4 into a functional opening 8 of the windshield 4.

[0069] The basic configuration of the wind shield 4 can correspond to the basic configuration of the floor apron 3, wherein in the present embodiment the wind slats 12 have a greater width along the longitudinal direction 14 than the floor slats 10.

[0070] As particularly in Figure 1bAs can be seen, the floor slats 10 are deformed to adapt to the surface 11. Particularly in the area of ​​the railway sleepers 16, the floor slats 10 are bent outward. In the area between the railway sleepers 16, the floor slats 10 are less curved toward the surface 11 and are supported, in particular, on the track substructure 17. Due to this adaptation of the floor apron 3 to the surface 11, the area between the retaining strip 2 and the surface 11 is covered by the floor apron 3.

[0071] To still allow a partial volume flow of the wind to pass through, the functional openings 8 are designed as through-openings. By selecting the size of these openings, the volume flow passing through can be precisely controlled.

[0072] The floor apron 3 and the wind shield 4 can comprise one or more base bodies 13.

[0073] Figure 2ashows, for example, an embodiment in which a single continuous base body 13 is provided, which forms both the floor skirt 3 and the windscreen 4. This base body 13 is connected in its central region between the two outer edges 7 to the retaining strip 2 and projects from the retaining strip 2 on the one hand towards the ground 5 and on the other hand upwards. This base body 13 of the Figure 2a can be formed, for example, by an elastomer band. This relief band is provided with incisions on both sides to form the lamellae. According to the invention, these incisions extend to functional openings 8. These functional openings 8 can, for example, be formed beforehand, before the incisions are formed, by cross-drilling.

[0074] Figure 2bshows an embodiment in which several base bodies 13 are provided. Thus, in the area of ​​the floor skirt 3 and the windshield 4, two base bodies 13 run parallel to each other. The floor skirt 3 and the windshield 4 are thus constructed in multiple layers, in particular in two layers.

[0075] This multi-layer structure can be used in particular to adjust the rigidity of the floor skirt 3 or the wind shield 4.

[0076] In particular, the floor apron 3 and the windshield 4 each comprise their own base body 13. As a result, the base body 13 of the windshield 4 can, for example, be designed to be stiffer than the base body 13 of the floor apron 3. The base body 13 of the windshield 4, made of a stiffer material, thus acts as a reinforcement to increase the strength of the windshield 4.

[0077] In the embodiment of the Figure 2bIn addition to the two base bodies 13 with different stiffnesses, there is also a continuous base body 13, as shown in Figure 2a shown. This continuous base body 13 runs parallel to the two other base bodies 13 and, in particular, rests against these base bodies 13.

[0078] Figure 2c shows a further embodiment in which the base body 13 of the windshield 4 is provided with a reinforcing bead. In this embodiment, this reinforcing bead runs along the outer edge 7 of the windshield 4.

[0079] Preferably, the functional openings 8 in all embodiments extend as through-openings through the floor apron 3 and / or the wind shield 4.

[0080] Preferably, in all embodiments, the track arrangement 1 is designed as a conventional track arrangement 1, to which, however, the deflector device is attached according to the invention. Preferably, the deflector device according to the invention is arranged in the region of a switch of the track arrangement 1. Particularly preferably, two deflector devices are arranged on both sides of the track arrangement 1, so that the at least one rail 15, in particular both rails 15 or the switch, is or are arranged between the two deflector devices.

[0081] In all embodiments, it may be provided that the incisions, in particular the main incisions 6 and / or the secondary incisions 9, run essentially perpendicular to the longitudinal direction 14, and in the intended installation position, essentially perpendicular. However, it is entirely conceivable for the incisions to run obliquely to the outer edge 7 or obliquely to the longitudinal direction 14. In the illustrated embodiments, all incisions run essentially parallel to one another. However, it is entirely conceivable for the incisions to run obliquely to one another.

[0082] According to an embodiment not shown, the arrangement comprises at least one windshield that is arranged transversely to the track or runs transversely to the track. This windshield runs in particular between two rails of a track arrangement and thus acts as a wind deflector against air movements flowing along the track. In particular, two such windshields can be provided—for example, at the beginning of a section to be protected and at the end of a section to be protected. The transverse windshield can be designed identically to the longitudinal deflector device and can protrude upwards from a retaining strip.

[0083] If necessary, a floor skirt is also provided on this retaining strip, which runs transversely to the track, to seal it off from the ground.

[0084] If appropriate, the transverse wind shield runs in the area of ​​a sleeper of the track arrangement. If appropriate, the transverse wind shield runs in the area between two sleepers of the track arrangement. Preferably, the wind shield, and in particular the retaining strip of the wind shield, is attached to a transverse sleeper.

[0085] In all embodiments, it can alternatively be provided that the windshield is designed to be continuous and therefore not slit. However, according to this alternative embodiment, functional openings can also be provided that pass through the windshield, so that an air flow is allowed through the windshield. Alternatively, however, these functional openings in the windshield can also be omitted, as long as it is ensured that sufficient air can pass through the functional openings in the floor skirt. According to any embodiment in which the windshield is not slit, i.e. in particular is designed to be continuous, one or more reinforcing beads can be arranged along the longitudinal direction of the windshield. For example, a reinforcing bead as in Fig. 2cIf necessary, at least one further such reinforcing bead can be provided, for example, running in the central region. Such a reinforcing bead improves, for example, the flexural rigidity of the windshield.

[0086] In all embodiments, it is preferably provided that the floor apron and / or the wind shield is or are connected to the track arrangement via a quick-release fastener, in particular via a fastener that can be operated without tools. This allows the deflector device or at least parts of the deflector device to be removed and installed quickly and easily. For example, the retaining strip is provided with mounting openings through which extensions can be inserted. These extensions can, for example, be rigidly or permanently connected to the track arrangement. The position of the retaining strip on these extensions can be fixed, for example, via elements that can be operated without tools, such as a cotter pin, a wing nut, or similar known elements.
