Description

Technical Field

[0001] This invention relates to an angle guide plate for securing a rail of a rail vehicle to a sleeper, comprising: a guide surface for lateral support on the bottom of the rail; a support surface arranged opposite to the guide surface for lateral support on the sleeper; two oppositely arranged end faces; a central axis extending perpendicularly to the guide surface; a through opening for screws extending from the upper side to the lower side of the angle guide plate; grooves for supporting two support sections of a tensioning clamp to be mounted on the angle guide plate in a final assembly position; two recessed surfaces for supporting the central ring portion of the tensioning clamp to be mounted on the angle guide plate in the final assembly position; and two receiving portions for supporting two spring arms of the tensioning clamp to be mounted on the angle guide plate in a pre-assembly position, wherein the central axis and the receiving portions are spaced apart in the longitudinal direction, and wherein the central axis and the end faces are half a length apart in the longitudinal direction.

[0002] The present invention also relates to a fixing system for securing the track of a rail vehicle to a sleeper, comprising: at least one corner guide plate, an elastic intermediate layer for placing on the sleeper below the track, and at least one tensioning clamp. Background Technology

[0003] The fixing of tracks and sleepers must meet many requirements. In its fixed state, the track must be able to withstand all static and dynamic loads exerted on it over a long period by parked or traveling rail vehicles and environmental influences (such as temperature fluctuations), while maintaining the required gauge. However, track fixing must also be quick and economical, as even relatively short lines require hundreds or even thousands of fixing points. When fixing the track, the track type and sleeper material (such as concrete or wood) must also be considered, which may lead to different fixing methods.

[0004] It has been found that single fasteners are insufficient to meet the increasingly stringent requirements for track fixing. Therefore, for many years, fixing systems comprising multiple components, such as tension clamps, corner guides, and elastic intermediate layers and / or gaskets, have been adopted. Many of these fixing systems can be pre-assembled (e.g., pre-fixed to concrete sleepers), so that the track can be simply inserted into the fixing system and secured.

[0005] An important component of this type of securing system is the so-called corner guide plate (sometimes also called "guide plate"). These are used to hold the rail in the correct position laterally by contacting the rail base, thus maintaining the rail in the correct track position. Another function of the corner guide plate is to support the tension clamp, both in the pre-assembled state and (in a changed position) in the final assembled state, i.e., in the working state where the rail is fixed. Therefore, the tension clamp must be held in a defined position in both the pre-assembled position and (different from) the final assembled position of the corner guide plate. Corner guide plates are installed on both sides of each rail, so typically four corner guide plates are used per sleeper.

[0006] Angle guide plates are known, for example, from EP 0 401 424 A1 or DE 102 54 679 A1. Further developments are described, for example, in EP 2 672 007 A1, WO 2010 / 003817 A1 and WO 2012 / 010269 A1.

[0007] What these corner guides have in common is that they are optimized for use with ω-shaped or W-shaped tension clamps, whose spring arms (at both ends) point inward (i.e., toward each other). These "ω-clamps" have gained international recognition and are widely used.

[0008] A new generation of tension clips has been developed, involving tension clips in which the spring arms point outward (opposite to each other). These tension clips are also known as "M-clamps" due to their shape, and are described, for example, in WO 2018 / 091351 A1. Tests have shown that this new tension clip exhibits excellent characteristics (higher natural frequency, greater spring travel). However, it has been found that the change in the direction of the spring arms makes pre-assembly of the new tension clip difficult, thus requiring significant modifications to other components of the fixing system, especially the corner guide plates. Summary of the Invention

[0009] Against the background described above, the object of the present invention is to design and improve the corner guide plate mentioned at the beginning and described in more detail above, as well as the fixing system mentioned at the beginning and described above, so that it can also be used for tensioning clamps with spring arms pointing outward (i.e., opposite to each other).

[0010] In the corner guide plate of the preamble of claim 1, this objective is achieved by the ratio of the distance between the receiving portion and the central axis to half the length being at least 0.5, preferably at least 0.6, at least 0.7 or at least 0.8.

[0011] The corner guide plate according to the invention is used to secure the track of a rail vehicle to sleepers, such as concrete sleepers. In the context of this invention, the concept of "sleeper" also includes so-called "ballastless track" (feste Fahrbahn), where the track foundation is not composed of ballast but rather a track superstructure composed of a solid support layer, such as a concrete layer. The corner guide plate first includes a guide surface for laterally supporting the rail base. This guide surface allows for the transfer of force laterally between the corner guide plate and the rail base to keep the track "on track." On the other side of the corner guide plate, i.e., on the side opposite the guide surface, the corner guide plate has a support surface through which the corner guide plate is laterally, i.e., laterally, supported on the sleeper. In this way, the lateral force introduced to the corner guide plate via the guide surface can be borne by the sleeper through the support surface. The corner guide plate also includes two oppositely arranged end faces and a central axis extending perpendicular to the guide surface, which preferably divides the approximately symmetrical corner guide plate into two equal-sized and axisymmetric halves. To simplify fixing to the sleepers, the angle guide plate also has a through-hole for screws, extending from the upper to the lower side of the angle guide plate. The angle guide plate also includes grooves for supporting two support sections of the tensioning clamp to be mounted on the angle guide plate in the final assembly position. These grooves serve as counter-supports for the support sections of the tensioning clamp. The angle guide plate also includes two recessed surfaces for supporting the central ring of the tensioning clamp to be mounted on the angle guide plate in the final assembly position. These recessed surfaces act as a stop for the tensioning clamp, particularly its central ring, when tightening the screws. The angle guide plate also has two receptacles for supporting two spring arms of the tensioning clamp to be mounted on the angle guide plate in the pre-assembly position. The central axis and the receptacles are spaced A apart in the longitudinal direction. L The central axis and the end face are half the length of each other in the longitudinal direction.

[0012] In order to also be able to use tensioning clamps with spring arms pointing outwards (i.e., opposite to each other), the present invention proposes that the distance A between the receiving part and the central axis be... LThe ratio to half the length is at least 0.5, preferably at least 0.6, at least 0.7, or at least 0.8. According to the invention, the two receiving portions of the spring arm are arranged very far from the central axis of the corner guide plate when viewed in the longitudinal direction, so that the two receiving portions are arranged as far apart from each other as possible in two opposing edge regions of the corner guide plate. A ratio of at least 0.5 means that the distance from the receiving portion to the central axis is at least 50% of half the length of the corner guide plate, thus the receiving portion is arranged in the edge region of the corner guide plate, which occupies a maximum of 50% of half the length of the corner guide plate. A ratio of at least 0.6 means that the distance from the receiving portion to the central axis is at least 60% of half the length of the corner guide plate, thus the receiving portion is arranged in the edge region of the corner guide plate, which occupies a maximum of 40% of half the length of the corner guide plate. Finally, a ratio of at least 0.7 or at least 0.8 means that the distance from the receiving portion to the central axis is at least 70% or at least 80% of half the length of the corner guide plate, thus the receiving portion is arranged in the edge region of the corner guide plate, which occupies a maximum of 30% or at most 20% of half the length of the corner guide plate. Therefore, the edge area where the receiving portion is located should occupy only the smallest possible portion of the length of the corner guide plate; in other words, the receiving portion should be arranged as close as possible to the edge of the corner guide plate. The increased distance between the receiving portions also allows for the accommodation of two tensioning clamps with a large spring arm spacing, such as tensioning clamps with spring arms pointing outwards (i.e., opposite to each other). Preferably, the receiving portion is designed so that the ends of the spring arms of the tensioning clamp can even extend beyond the end face of the corner guide plate, thus allowing the use of tensioning clamps longer than the corner guide plate. The advantage is that the length of the corner guide plate can remain constant, thus eliminating the need to adjust the width of the sleeper. Another advantage of the larger distance between the two receiving portions is the greater support width, which provides better anti-overturning stability of the tensioning clamp in the pre-assembled position.

[0013] According to one design of the corner guide plate, the receiving part has a generally horizontally extending placement surface and an adjacent slope that rises from the placement surface toward the guide surface. The rising slope restricts the lateral movement of the tensioning clamp toward the track in the pre-assembly position, keeping the "track channel" required for track insertion unobstructed, thus eliminating concerns about collisions with the tensioning clamp during track insertion.

[0014] The design further proposes that the placement surface of the receiving part has a placement height, which represents the vertical distance between the lower side and the placement surface; the corner guide plate has a height in the area adjacent to the receiving part, which represents the distance between the upper and lower sides; and the ratio of the height of the placement surface of the receiving part to the height of the upper side is at least 1.5, especially at least 1.55 or at least 1.6. Therefore, the placement surface of the receiving part should be in an elevated position relative to the conventional height of the corner guide plate, and at least 50% (ratio 1.5), especially at least 55% (ratio 1.55) or at least 60% (ratio 1.6). This elevated position facilitates pushing the tensioning clamp, especially the spring arm of the tensioning clamp, from the receiving part (pre-assembly position) to the rail base (final assembly position). Particularly in the case of the aforementioned "M-clamp," pushing the tensioning clamp between these two positions is challenging because the outward (opposite to each other) pointing spring arms of these tensioning clamps typically also point slightly downward to create a larger placement surface on the inclined rail base. However, this orientation of the spring arm makes it more difficult to push it towards the rail base, as the end of the spring arm can collide laterally with the rail base during pushing. However, if the housing is of sufficient height, the tensioning clamp can be pushed onto the upper side of the rail base without impact by its spring arm. By matching only the height of the housing, rather than the entire corner guide plate, the corner guide plate can be designed to be lighter and more economical.

[0015] According to another design of the corner guide plate, the guide surface and the receiving part are spaced at least 6 mm apart in the lateral direction, preferably at least 7 mm. This spacing is designed to ensure that when the tensioning clamp is supported on the receiving part (i.e., in the pre-assembled position), no part of it encroaches on the track channel. This allows the track channel to remain sufficiently wide in the pre-assembled position so that the track can be inserted from above between the pre-assembled corner guide plate and the tensioning clamp without collision.

[0016] According to another embodiment of the corner guide plate, the slope of the receiving portion has an edge at its upper end, which has an edge height representing the vertical distance between the lower side and the edge, and is at least 21 mm, and particularly at least 22 mm. The upper edge of the slope of the receiving portion constitutes the highest point that the spring arm of the tensioning clamp must cross when pushed from the pre-assembly position to the final assembly position. So far, it has generally been avoided to position this edge too high, as an excessively high edge makes pushing the tensioning clamp difficult. However, it has been recognized that, particularly for tensioning clamps where the spring ends not only face outwards (away from each other) but also point slightly downwards, raising this edge is advantageous, because only when the edge is in a sufficiently high position can the end of the tensioning clamp be pushed onto the rail base without impact. Raising the position of this edge is especially necessary when the placement surface of the receiving portion already has an increased height; otherwise (i.e., when the slope and its upper edge are too low), there is a risk that the spring arm will accidentally slip into the rail passage.

[0017] Another design option for the corner guide plate is to make it from plastic, particularly fiber-reinforced plastic. Using plastic allows for cost-effective production while maintaining light weight. Another advantage of plastic is its electrical insulation and high corrosion resistance. For withstanding high static and dynamic loads, fiber-reinforced plastics, such as glass fiber reinforced plastic, can be used.

[0018] In the fixing system described in the preamble of claim 7, the aforementioned objective is achieved by structurally designing the corner guide plate according to any one of claims 1 to 6. The corner guide plate should therefore be designed according to claims 1 to 6, achieving the advantages already stated above, particularly enabling the use of tension clamps with spring arms pointing outwards (opposite to each other). This fixing system is used to fix rails for rail vehicles to sleepers. The fixing system firstly includes at least one corner guide plate, the construction and function of which have been described above. The fixing system also includes an elastic intermediate layer beneath the rail that contacts the sleeper. This intermediate layer serves, for example, to dampen vibrations (such as those caused by uneven wheels) and ensure electrical insulation. Furthermore, this intermediate layer also enables uniform load distribution. This intermediate layer may be made of an elastomer, such as EPDM (ethylene propylene diene monomer rubber). Finally, the fixing system includes at least one tension clamp. The tension clamp is used to elastically tension the rail base to the sleeper. The tension clamp is made of steel, preferably spring steel.

[0019] According to one design scheme for the fixation system, the tensioning clamp has two outward-pointing spring arms, roughly in an M-shape. This type of "M-clamp" exhibits improved performance (higher natural frequency, better durability) compared to traditional "W-clamps" or "ω-clamps," but it is more difficult to operate due to its outward-pointing (opposite to each other) and slightly downward-pointing spring arms. The "M-clamp" can also be integrated into the fixation system in a conventional manner using an adapted shape of the corner guide plate.

[0020] Another design for the fixing system specifies that the tensioning clamp has a first natural frequency of at least 800 Hz, particularly at least 900 Hz, and more preferably at least 1000 Hz. The service life of the tensioning clamp depends decisively on its vibration behavior. Tensioning clamps typically have multiple natural frequencies, the lowest of which is also called the "first natural frequency." During use, when a train passes over the track pressed by the tensioning clamp, it excites the clamp to vibrate. To avoid potential resonance and the resulting increase in amplitude in the tensioning clamp's spring arm region, the tensioning clamp's natural frequency should be as far away as possible from the excitation frequency generated by periodic vibrations (e.g., due to uneven wheels or track irregularities). Using a tensioning clamp with a particularly high natural frequency significantly reduces this risk, thereby significantly extending its service life. It has been found that a first natural frequency of at least 800 Hz, particularly at least 900 Hz, and especially at least 1000 Hz is above the frequency range where excitation typically occurs in practice, and therefore, a first natural frequency within this range can provide the aforementioned advantages.

[0021] According to another design scheme for the fixing system, the length of the tensioning clamp in the longitudinal direction of the track is greater than that of the corner guide plate, such that in the final installation position, the two spring arms of the tensioning clamp extend beyond the ends of the corner guide plate. Tensioning clamps with outward-pointing spring arms (“M-clamps”) sometimes have a considerable length (the distance between the ends of the two spring arms). This length cannot be arbitrarily shortened without sacrificing ideal performance (high natural frequency, good durability). On the other hand, for a given width of sleeper, the length of the corner guide plate cannot be arbitrarily increased. Therefore, it is recognized that the ends of the spring arms of the tensioning clamp can protrude outward from both ends of the corner guide plate. In this way, particularly “long” tensioning clamps can be used without adjusting the dimensions of the corner guide plate, and even less so without adjusting the width of the sleeper. This is particularly advantageous when using tensioning clamps with outward-pointing spring arms, since the distance between the ends of the two spring arms typically determines the total length of the tensioning clamp.

[0022] According to further design options, the fixing system can be supplemented with at least one screw, and preferably at least one expansion tube. Using a screw and expansion tube to secure the tension clamp creates a particularly efficient, safe, and durable connection. The screw can be tightened very quickly with an impact wrench, where the desired torque can be set. By matching the geometry of the screw to the geometry of the expansion tube, a particularly strong and long-term reliable connection can be achieved. A particular advantage of using an expansion tube is that it eliminates the need for threads in the sleeper, which is especially simplified for concrete sleepers, as expansion tubes cast into the sleeper can be used (conversely, for wooden or plastic sleepers, expansion tubes can be tightened directly without them; in these cases, the expansion tube can be omitted). The expansion tubes used are preferably made of plastic. Attached Figure Description

[0029] Figure 1 A perspective view shows the corner guide plate 1 according to the invention. The corner guide plate 1 has a through opening 2 in its central region for receiving screws 15 (see...). Figure 4 , Figure 5 The corner guide plate 1 can be threaded onto the sleeper 18 via this screw (see...). Figure 4 , Figure 5 Angle guide plate 1 is located on its lower side 11 (see...). Figure 3 The sleeper 18 has a shoulder 3, which can be inserted into a corresponding groove 19 formed on the upper side of the sleeper 18 (see...). Figure 4 , Figure 5 The outer side (facing away from the track) of the corner guide plate 1 forms a support surface 4, through which the corner guide plate 1 can be laterally (i.e., in a direction transverse to the track 17) supported on the sleeper 18, for example, supported on the shoulder of the upper side of the sleeper 18 (see...). Figure 4 , Figure 5 The inner surface (facing the track) of the corner guide plate 1 is formed as a guide surface 5, which is used to provide lateral support for the rail base 17A (see above). Figure 4 , Figure 5 The corner guide plate 1 also has two opposing end faces 6.

[0030] Figure 1 The corner guide plate 1 shown also has multiple areas on its upper side 10 for holding the tensioning clamp 14 in a defined position (see...). Figure 4 , Figure 5The corner guide plate 1 has a groove 7 on its upper side 10 in its outer region (away from the track), which is used to support the two outer support sections 21 of the tensioning clamp 14 in the final installation position (see...). Figure 4 , Figure 5 Meanwhile, the end of the spring arm 20 contacts the rail base 17A in the final installation position (see...). Figure 4 , Figure 5 The corner guide plate 1 also has two receiving portions 8 on its upper side 10 in its inner region (facing the track) for supporting the spring arm 20 in the pre-assembled position (see...). Figure 4 , Figure 5 Each of the two receiving portions 8 has a nearly horizontally extending placement surface 8A and an adjacent curved slope 8B that rises from the placement surface 8A toward the guide surface 5. The upper side 10 of the corner guide plate 1 also has two recessed surfaces 9, which serve as stop surfaces for the central ring portion 22 of the tension clamp 14.

[0031] Figure 2 Shown in top view Figure 1 Corner guide plate 1. All combinations Figure 1 The marked area of ​​corner guide plate 1, in Figure 2 The corresponding reference numerals are marked on all the figures. In the top view, the central axis M is visible, which extends perpendicularly to the guide surface 5 and passes through the corner guide plate 1 at the center. From this central axis M, the corner guide plate 1 has a length L / 2 in the longitudinal direction (i.e., along the direction of track 17) to its end face 6, which can be between 50 mm and 60 mm. The longitudinal distance A is also visible in the top view. L This distance represents the distance between the central axis M and the receiving part 8. This distance A L For example, it can be in the range of 40 mm to 50 mm. Therefore, the receiving part 8 is arranged longitudinally at the starting position or the end position of the corner guide plate 1. The lateral distance A is also visible in the top view. Q This distance represents the distance between the guide surface 5 and the receiving part 8. This distance A Q For example, it can be at least 6 mm, especially at least 7 mm, to ensure that the tensioning clamp 14 maintains a sufficient distance from the track channel in the pre-assembled position so that it can be smoothly inserted into the track 17.

[0032] Figure 3 Shown in front view Figure 1 Corner guide plate. All combinations Figure 1 or Figure 2 The area marked with corner guide plate 1, in Figure 3The corresponding reference numerals are marked on all the figures. The front view shows particularly clearly that the corner guide plate 1 has an upper side 10 and a lower side 11, which extend approximately parallel to each other, and the corner guide plate 1 has a height H0 therebetween (H0 may be, for example, between 10 mm and 14 mm). It can also be seen that the placement surface 8A of the receiving portion 8 has a placement height H1, which represents the vertical distance between the lower side 11 and the placement surface 8A. For example, this placement height H1 may be at least 18 mm, especially at least 19 mm; thus, the placement surface 8A is raised relative to the normal height H0 of the upper side 10. It can also be seen that the upper edge 12 of the slope 8B of the receiving portion 8 has an edge height H2, which represents the vertical distance between the lower side 11 and the edge 12, and may be, for example, at least 21 mm, especially at least 22 mm. This upper edge 12 represents the highest point that the spring arm 20 of the tensioning clamp 14 must cross when pushed from the pre-assembled position into the final assembled position of the rail base 17A (see figure). Figure 4 , Figure 5 The edge 12 must have a minimum height so that the spring arm 20 of the tension clamp 14 will not strike the rail base 17A laterally during pushing, but can be pushed to the upper side of the rail base 17A. The guide surface 5 has a notch 5A in its lower region adjacent to the lower side 11, which is used to accommodate the ( ) laid below the rail base 17A.

[0033] Figure 4 A front view of the fixing system 13 with track 17 according to the present invention is shown. The corner guide plate 1 is already integrated... Figures 1 to 3 The marked area is Figure 4 Corresponding reference numerals are also provided in the accompanying drawings. The fixing system 13 is in... Figure 4 The left half shows the pre-assembly position, while... Figure 4 The right half shows the final assembly position. In addition to the two corner guide plates 1 mentioned above, the fixing system 13 also includes two tension clamps 14 and two matching ( Figure 4 (Not shown) Screws 15 for the expansion tube and an elastic intermediate layer 16. Fixing system 13 is used to fix the rail 17 to the sleeper 18. The rail 17 includes a rail base 17A, a rail web 17B, and a rail top 17C.

[0034] The fixing system 13 can be pre-assembled by placing the intermediate layer 16 and two corner guide plates 1 on the sleeper 18. During this process, the corner guide plates 1, with their shoulders 3 on their lower sides 11, are inserted into corresponding shaped grooves 19 on the upper side of the sleeper 18. In this way, the corner guide plates 1 are particularly well supported laterally (i.e., transversely to the track 17) on their support surfaces 4, thus ensuring that the track 17 maintains a precise gauge. The tension clamp 14 can also be pre-assembled by placing it in the pre-assembly position of the corner guide plates 1. The tension clamp 14 is held in its pre-assembly position by slightly tightened screws 15, for which the screws 15 are guided through the central ring 22 of the tension clamp 14 and the through opening 2 of the corner guide plates 1, and tightened together with the sleeper 18—in the case of concrete sleepers, an expansion tube matching the screws 15 is preferred. Figure 4 In this pre-assembly position shown on the left, the two spring arms 20 of the tension clamp 14 are held in the aforementioned receiving portion 8 of the corner guide plate 1, while the two support sections 21 of the tension clamp 14 extend laterally beyond the corner guide plate 1 and are supported on the sleeper 18. This pre-assembly position of the tension clamp 14 ensures that the "track channel" formed between the two opposing tension clamps 14 remains unobstructed, allowing the rail 17 to be inserted into the track channel from above without colliding with the pre-assembled tension clamp 14.

[0035] In contrast, Figure 4 The right half shows the fixing system 13 in the final assembly position. Pre-assembly position ( Figure 4 Left side) and final assembly position ( Figure 4 The main difference on the right side is that the tensioning clamp 14 has been pushed from the outside in (i.e., towards the rail 17), and the two support sections 21 of the tensioning clamp 14 are pulled from the sleeper 18 into the grooves 7 of the corner guide plate 1. Furthermore, during the pushing of the tensioning clamp 14, its two spring arms 20 are pushed out of the receiving portion 8 and onto the rail base 17A. During this pushing process, the spring arms 20 of the tensioning clamp 14 must cross the edge 12. Finally, the screws 15, which were previously only pre-tensioned, are tightened to the specified torque, wherein the central ring portion 22 of the tensioning clamp 14 (in...) Figure 4 The central part of the obstruction is pressed against the recessed surface 9 of the corner guide plate 1 (see...). Figure 5 And the spring arm 20 of the tensioning clamp 14 presses down to tighten the bottom rail 17A.

[0036] Figure 5 Finally, it showed Figure 4 The diagram shows a perspective view of the fixing system 13. The fixing system 13 and its corner guide plate 1 are already integrated... Figures 1 to 4 The marked area is Figure 5Corresponding reference numerals are used in the accompanying drawings. In the perspective view, track 17 is shown in a transparent manner to make some components of the fixing system 13 more clearly visible. The position of the tension clamp 14 in the pre-assembly position (left) and the final assembly position (right) is particularly clear: in the pre-assembly position, the two support sections 21 of the tension clamp 14 are placed on the sleeper 18, while its two spring arms 20 are received in the receiving portion 8 of the corner guide plate 1, wherein the ends of the spring arms 20 may extend beyond the edge of the corner guide plate 1 on both sides longitudinally—that is, along the direction of track 17. In the pre-assembly position (left), the central ring portion 22 of the tension clamp 14 is not in contact with the recessed surface 9 of the corner guide plate; therefore, the central ring portion 22 is “suspended” above the recessed surface 9. Conversely, in the final assembly position, both support sections 21 of the tension clamp 14 are arranged in the grooves 7 of the corner guide plate 1, while the two spring arms 20 have left the receiving portion 8 and are placed on the rail base 17A. In the final assembly position (right side), the central ring 22 of the tensioning clamp 14 is pressed down by the screw 15, so that the tensioning clamp 14 contacts the two recessed surfaces 9 of the corner guide plate 1.
