Description

[0001] Device and method for producing a ramp between rail sections of different groove depths and use of this device

[0002] The invention relates to a device and a method for producing a ramp between grooved rail sections of different groove depths.

[0003] In track superstructures, it is regularly necessary to connect track sections with different groove depths via ramps, for example, in the area of ​​shallow groove crossings or switches. An overflow frog for a shallow groove switch is described, for example, in EP 2520711 A2. The increased interconnection of tram and railway networks, also known as "tram-train," to create direct connections between tram and railway lines without changing trains, which frequently use different groove depths, is also increasingly leading to the need to connect track sections with different groove depths. The ramps, also known as "approach or exit ramps," ensure that the groove depth between a track section with a deep groove and a track section with a shallow groove is equalized.

[0004] Guidelines for ramping the groove base in shallow grooves are contained, for example, in VDV publication 600 “Superstructure guidelines and additional guidelines for railways within the scope of BOStrab” published by the Association of German Transport Companies (see VDV 600:2018-08, Chapter 10.3.2.4.6).

[0005] The approach ramps between deep-grooved and shallow-grooved tracks are subject to increased wear due to contact between the grooved track and the wheel flange of the flanged wheels running on them, necessitating appropriate maintenance and repair work. Currently, the approach / departure ramp in shallow-grooved tracks is repaired using a rail-guided grinding machine after welding. The grinding machine is manually moved back and forth over the shallow-grooved track, while the height of the grinding head is manually adjusted along the Z-axis using a handwheel or hand crank to grind the ramp to the specified incline of, for example, 1:100. Currently, the correct incline can only be verified by manual visual inspection.With this conventional repair method, the precise creation of a correct ramp is therefore not possible, especially in curves. This can result, for example, in the entry / exit ramps on adjacent rails of a track not running parallel to each other or being uneven in height. Poor and inaccurate repair of entry / exit ramps causes damage to the wheel rims or flanges of the rail vehicles, as well as to the flat grooved track systems themselves. The resulting downtime, as well as shortened repair intervals and downtimes of the flat grooved track systems, result in increased costs.

[0006] The object of the present invention is to enable or at least facilitate the production, in particular the repair, of an on-ramp / off-ramp between grooved rail sections of different groove depths with a specified incline, in particular one that complies with guidelines. In particular, the invention aims to enable the reliable production of a correct on-ramp / off-ramp using a simple device.

[0007] To achieve the object, the invention provides a device for producing a ramp of length Lr between a first grooved rail section of a grooved rail with a first groove depth TI and a second grooved rail section of the grooved rail with a second groove depth T2 different from the first groove depth RI, wherein the ramp comprises at least a first ramp section of length Lrl with an inclination Sri, wherein the device

[0008] - extends in a longitudinal direction from a first end to a second end,

[0009] - comprises a support surface and a surface opposite the support surface with at least a first surface portion, wherein the first surface portion extends in the longitudinal direction of the device at least over a length Lol which corresponds to at least a part of the length Lrl,

[0010] - is composed of a plurality of pivotally connected members forming the surface, and

[0011] - flattens in a wedge shape in the longitudinal direction from its first end to its second end at least in the region of the first surface section over the length Lol, so that the surface in the region of the first surface section has an inclination Sol corresponding to the inclination Sri with respect to the support surface.

[0012] The device according to the invention enables the simple and reliable production of a ramp with the correct incline between two grooved rail sections with different groove depths, for example, a grooved rail section with a deep groove and a grooved rail section with a shallow groove. The device according to the invention can advantageously be used as an aid to continue using the previous production method using a rail-guided grinding machine, albeit with significantly improved precision and reliability. The device can also be designed to produce two- or multi-stage ramps. Thanks to the articulated links, the device can also be used in curved sections. The device is robust, simple to manufacture and use, and can be easily assembled or disassembled as needed.It's easy to transport and store, saving space, and requires little maintenance or upkeep.

[0013] The core idea of ​​the invention is to provide a mechanical device that is easy to manufacture and use as an aid for producing a ramp with a predetermined inclination between two grooved rail sections with different groove depths in order to improve the existing methods of ramping the groove bottom by means of grinding and / or welding and to make them more reliable.The device according to the invention is in principle itself a portable, wedge-shaped ramp which, in order to adapt to rail areas with curvatures or curves, can be bent or curved in the transverse direction to the longitudinal direction, if necessary by means of the articulated members, and which, on the one hand, can be placed with its support surface on the rail head or a plane or surface running parallel thereto and, on the other hand, can be driven over by a milling, welding or grinding machine on the surface opposite the support surface.The inclination of the surface of the device according to the invention corresponds to the inclination of the ramp or a ramp section to be produced, so that the milling, welding or grinding head of a milling, welding or grinding machine moved thereon can be set to a constant vertical distance and the inclination of the surface of the device can be transferred to the groove bottom by means of the milling, welding or grinding head in the area of ​​the ramp or the ramp section.

[0014] The term "construction" in relation to an on- or off-ramp includes both the construction and restoration of an on- or off-ramp, as well as the repair of an existing on- or off-ramp, not only, but preferably, in situ (on-site). The term "repair" includes all measures to remedy damage to an on- or off-ramp, including the complete or partial replacement or repair of components of the on- or off-ramp.

[0015] The terms “ramp”, “ascent or descent ramp” or “ascent / descent ramp” refer to a connecting piece for compensating for the difference in groove depth between grooved rail sections of a rail with different groove depths, i.e. a ramp-like ascending or descending connecting piece between the groove bottoms of two grooved rail sections with different groove depths T, for example between a deep grooved rail and a shallow grooved rail. When the term “ascent ramp” is used in isolation here, this is not to be understood as meaning only an “ascending” ramp from a deep groove to a shallow groove, unless the context clearly indicates otherwise. Conversely, the term “descent ramp” when used in isolation is not to be understood as meaning only a “descending” ramp from a shallow groove to a deep groove, unless the context clearly indicates otherwise.The term "ramp" encompasses single-, double-, or multi-stage ramps, i.e., ramps with only one, two, or more ramp sections, each with a specific, different gradient. For example, a ramp can consist of a ramp section with a relatively steep gradient ("steep ramp") and a ramp section with a comparatively shallow gradient ("flat ramp," e.g., 1:100).

[0016] The term "inclination" refers to the incline or decline of a ramp, a ramp section, or the plane formed by the surface of the device according to the invention relative to the horizontal and / or the travel plane of the travel head of the rail in its longitudinal direction. A predetermined incline S of 1:100 with respect to a ramp means, for example, an incline or decline of the ramp of 1:100 (rise or fall by one height unit for a length L of 100 length units). A gradient of 1:100 corresponds to an incline of 1% or 0.573°. A gradient of 10.50% corresponds to an incline of 10.5:100 or 5.99°. The term "constant incline" refers to a continuously variable, uniform incline or decline (decline).

[0017] The term "wedge-shaped flattened" in relation to the device according to the invention means that the device is generally wedge-shaped and has two surfaces that converge toward one of the ends of the device. This includes embodiments of the device in which the surfaces converge at an acute angle toward one of the ends of the device, but also includes embodiments in which the tapered end is not pointed but blunt.

[0018] When the term "flat support surface" is used here, it means that the support surface extends in a single plane. However, this does not exclude the possibility that the support surface is "uneven" in the sense that it has profiles, serrations, roughening, or the like, for example, to increase slip resistance.

[0019] When the term “horizontal” is used here, it means a horizontal position, i.e. a position parallel to a flat earth surface.

[0020] As used herein, the term "parallel to," for example, in reference to the movement of a milling, welding, or grinding head, may also imply that the referenced parallel structures coincide and are not spaced apart. For example, a phrase such as that a milling, welding, or grinding head is parallel to a ramp or ramp section implies that the milling, welding, or grinding head lies within the surface of the ramp or ramp section.

[0021] The expression that the device according to the invention is composed of "a plurality of pivotally connected links" means that the device is composed of individual, separate links that are pivotally connected to one another in a chain-like manner. "Pivotally connected" in relation to the device according to the invention means that the links are each mounted for rotation about an axis that runs perpendicular to the support surface. "Chain-like" connection means that the links are arranged one behind the other. Each link, with the exception of the last link, is connected to only one follower link. A "follower link" is understood to be a link that directly follows a specific link in the link chain in one direction, preferably the longitudinal direction, of the device, and is thus downstream of the link and connected to the link.

[0022] The term “in situ” here refers to use on site, i.e. on a track or rail that has already been laid.

[0023] When reference is made here to a length, in particular to the length of a surface area or a ramp area, the length refers to the extent in the horizontal direction. For example, a formulation referring to a length L of a surface area of ​​the device refers to the length of the device in the longitudinal direction within the surface area of ​​the device, not to the length of a line from the beginning to the end of the surface area, which would be greater due to the inclination. In relation to the device, the length corresponds to the distance between two perpendiculars dropped onto the support surface at the beginning and end of the surface area. The same applies to lengths relating to the ramp or ramp sections. Here, the lengths refer to the lengths of the corresponding sections when projected onto the grooved rail travel head.

[0024] A “grooved rail” is understood here to be a railway rail with a groove provided in the rail head, for example a rolled-in groove. The rail head of such a grooved rail comprises a running rail with a running rail head and a guide rail with a guide rail head as well as a groove formed between the running rail and the guide rail. A “deep-grooved rail” is understood here to be a grooved rail with a comparatively deep groove, for example a rail with a groove depth T of 47 mm. A “shallow-grooved rail” is understood here to be a grooved rail with a comparatively shallow groove, for example a rail with a groove depth T of 14 mm. In the case of flat-grooved rails, the greatest groove depth is smaller than the minimum wheel flange height of the rail vehicles used in the rail system. A “switch arrangement” is understood here to be a rail arrangement for changing the lane in rail-bound means of transport, i.e.Rail vehicles. A switch assembly enables rail vehicles to switch between different tracks without interrupting their journey. A "flat-groove switch" is a switch assembly that includes at least one flat-grooved rail or a section with a flat-grooved rail, i.e., with areas where the flanged wheel of a rail vehicle runs on the flange.

[0025] The term “rail-guided” refers to the presence of device elements, such as flanged wheels or guide rollers, which enable the device, e.g. a milling, welding or grinding machine, to travel on a track or at least one rail thereof.

[0026] When the terms ‘horizontal’ or ‘vertical’ are used herein with reference to the movement of a milling, welding or grinding head of a milling, welding or grinding machine, these terms refer, unless the context clearly indicates otherwise, to the plane of the running surface of the running head of the rail on which the milling, welding or grinding machine is mounted.

[0027] The term "portable" in relation to a device according to the invention means that the weight of the device is within a range that allows the device to be transported as a whole or divided into a maximum of two or three parts by a maximum of two people using muscle power. The weight of the device can, for example, be in the range of 0.2 to 55 kg, preferably in the range of 0.2-50 kg, 0.2-40 kg, 0.2-30 kg, 0.2-25 kg or 0.2-20 kg, or, for example, in the range of 0.5-30 kg, 0.5-25 kg or 1-20 kg. By suitable design and / or use of suitable materials, for example light metals, e.g., aluminum, or suitable plastics, the weight of the device can be kept within a portable range. If necessary, the device can be designed such that it can be divided into two or three composable parts.In a preferred embodiment of the device according to the invention, the device comprises a starting link and an end link, as well as at least one, preferably at least two, three or more intermediate links arranged one behind the other between the starting and end links, or consists of a starting link, end link, and one, two or more intermediate links, wherein at least some of the links, preferably all of the links, are pivotally connected to one another. The starting, end, and intermediate link(s) are connected to one another in a chain-like manner. The starting and end links are not directly connected to one another, so that the device has open ends.

[0028] In a particularly preferred embodiment of the device according to the invention, the device is portable and designed such that it can be placed with the support surface on a travel head of a grooved rail or a plane or surface running parallel thereto, and comprises or consists of a plurality of links connected to one another in a chain-like manner, including a start link, an end link and at least one intermediate link, preferably two or more intermediate links, wherein the links are pivotally connected to one another in such a way that the links can each be rotated about an axis which is perpendicular to the support surface, and wherein the links together form an inclined surface which can be traveled over, for example, by a milling, welding or grinding machine.

[0029] In a preferred embodiment of the device according to the invention, the members are pivotally connected to one another via screw connections. However, the pivotal connections can also be implemented in other suitable ways, for example, by pin or bolt connections.

[0030] In a further preferred embodiment of the device according to the invention, the length Lol of the first surface section corresponds to the full length Lrl of the first ramp section. In this embodiment, the surface section of the surface formed by the plurality of pivotally connected members is as long as the ramp section to be produced. The surface section thus runs parallel to the ramp section to be produced over the entire length. In the case where a single-stage ramp is to be produced, the length Lol of the first surface section preferably corresponds to the total length Lv of the surface of the device and the total length Lr of the ramp.

[0031] The inclination Sol of the surface of the device can be adapted to the respective conditions or the specifications for the inclination Sri of the ramp section and can be, for example, 1:100.

[0032] The device can be used to produce a ramp that has a uniform gradient S over its entire length Lr. However, the device can also be designed to serve as an aid in forming a two- or even multi-stage ramp. For example, it is not uncommon to implement the approach to, for example, shallow grooves with a two-stage ramp, i.e., a ramp with a first and a second ramp section. The first ramp section can be designed as a steep ramp with a steeper gradient, followed by the second ramp section with a lower gradient.In a further preferred embodiment of the device according to the invention, the ramp therefore comprises a first ramp section of length Lrl with an inclination Sri and a second ramp section of length Lr2 with an inclination Sr2, wherein the surface toward the second end of the device comprises a second surface section of length Lo2 with an inclination So2 that is greater than the inclination Sol of the first surface section, and wherein the inclination So2 corresponds to the inclination Sr2. The surface of the device here has two sections that have a different inclination.As an aid for producing, for example, a ramp which has a second ramp section of length Lr2 designed as a steep ramp with an incline Sr2 and a first ramp section of length Lrl designed as a flat ramp with an incline Sri, the surface has corresponding sections with corresponding lengths Lol and Lo2 as well as inclines So2 and Sol, so that with appropriate arrangement of the device on the grooved rail in the area of ​​the ramp to be produced, both the section of the ramp to be formed as a steep ramp and the section to be formed as a flat ramp can be produced in one work process.

[0033] In a further aspect, the invention also relates to an arrangement comprising a) a grooved rail comprising a travel head, a first grooved rail section with a first groove depth TI, a second grooved rail section with a second groove depth T2 that differs from the first groove depth TI, and a ramp arranged between the first grooved rail section and the second grooved rail section and connecting the groove bottoms of the grooved rail sections, wherein the ramp comprises at least a first ramp section of length Lrl with an inclination Sri, and b) a device according to the invention arranged with its support surface on the travel head of the grooved rail, wherein the device is arranged on the travel head of the grooved rail such that the surface with its first surface section of length Lol and inclination Sol runs parallel to the first ramp section of length Lrl with inclination Sri.

[0034] In a preferred embodiment of the arrangement, the ramp comprises a first ramp section of length Lrl with an inclination Sri and a second ramp section of length Lr2 with an inclination Sr2, wherein the device is arranged with its support surface on the travel head of the grooved rail such that the surface with its first surface section with the length Lol and inclination Sol runs parallel to the first ramp section of length Lrl with the inclination Sri, and with its second surface section with the length Lo2 and inclination So2 runs parallel to the second ramp section of length Lr2 with the inclination Sr2.

[0035] In a further aspect, the present invention also relates to a method for producing a ramp of length Lr between a first grooved rail section of a grooved rail with a first groove depth TI and a second grooved rail section of the grooved rail with a second groove depth T2 different from the first groove depth TI, comprising the following steps: a. Placing a device according to the invention, as described above, with its support surface on the travel head of the grooved rail or a flat grooved rail environment running parallel to the grooved rail, so that the surface of the device runs parallel to the ramp to be produced; b.Arranging a milling, welding or grinding machine with a milling, welding or grinding head on the device such that the milling, welding or grinding head moves vertically when the milling, welding or grinding machine moves in the longitudinal direction of the device parallel to the surface of the device and parallel to the ramp to be produced; and c. Milling, welding or grinding the ramp between the first grooved rail section of the grooved rail with the first groove depth TI and the second grooved rail section of the grooved rail with the second groove depth T2.

[0036] In the method according to the invention, an embodiment of the device according to the invention described in more detail above is placed with its support surface on the travel head of the grooved rail for which a ramp is to be produced between the groove bottoms of different depths, or on a suitable area of ​​the rail surroundings adjacent to the grooved rail, such that the surface of the device runs parallel to the ramp to be produced and the inclination of the surface of the device can be easily transferred to the ramp to be produced via the milling, welding or grinding head of a milling, welding or grinding head machine that can be moved on the surface of the device. For example, a ramp or at least a ramp section with an inclination of 1:100 can be easily produced using a device whose surface has an inclination So of 1:100.Once the device has been correctly positioned and, if necessary, adjusted to a rail curvature by adjusting the links relative to each other, the elements of the device can be secured against unintentional adjustment, for example, by tightening the screws provided for this purpose. It is preferred that the device be spaced apart from the groove-facing flank of the travel head to prevent contact between the device and the milling, welding, or grinding head. A suitable spacer can be used for this purpose.

[0037] In a preferred embodiment of the method according to the invention, the ramp to be produced comprises a first ramp section of length Lrl with an inclination Sri and a second ramp section of length Lr2 with an inclination Sr2, and the surface of the device comprises a first surface section with the length Lol and inclination Sol and a second surface section with the length Lo2 and inclination So2. In this embodiment of the method according to the invention, the device is placed on the travel head of the grooved rail in step a such that the surface of the device with its first surface section with the length Lol and inclination Sol runs parallel to the first ramp section of length Lrl with the inclination Sri and the surface with its second surface section with the length Lo2 and inclination So2 runs parallel to the second ramp section of length Lr2 with the inclination Sr2.In step b, the milling, welding, or grinding head of the milling, welding, or grinding machine moves vertically while the milling, welding, or grinding machine moves in the longitudinal direction of the fixture, parallel to the first and second surface sections of the fixture and parallel to the first and second ramp sections of the ramp to be produced. In this way, a two-stage ramp with ramp sections of different inclinations can be produced in a single work step.

[0038] In a further aspect, the present invention also relates to the use of a device according to the invention, as described above, for producing a ramp or a ramp section between a first grooved rail section of a grooved rail having a first groove depth and a second grooved rail section of the grooved rail having a second groove depth different from the first groove depth.

[0039] The invention is explained in more detail below with reference to the attached drawings purely for illustrative purposes.

[0044] Figure 1 shows a preferred embodiment of a device 1 according to the invention in longitudinal section (A) along the dash-dotted line in Figure 1B and in plan view (B). For an enlarged view of the end regions of the device, reference is made to Figure 2. As can be seen from Figure 1A, the device 1 is generally wedge-shaped, i.e. it tapers from its first end 3 to its second end 4. It is composed of links 7, 8, 9 that are pivotally connected to one another. In the embodiment shown here, the device 1 consists of an initial link 8 located towards the first end 3, an end link 9 located towards the second end 4, and fifteen intermediate links 7 in between. The links 7, 8, 9 are pivotally connected to one another via screw connections 10.For this purpose, the links 7 have a projection 12 which can be received in a corresponding recess 13 of a subsequent link 7 and fixed by means of the screw connection 10 such that the links 7 are held together but remain rotatable about the axis of rotation 18 formed here by the screw connection 10. In this embodiment, the initial link 8 has only one projection 12, and the end link 9 only one recess 13. However, pin and / or bolt connections can also be used to pivotally connect the links 7, 8, 9. The device 1 can be completely disassembled into its component parts, i.e., the links 7, 8, 9. The device 1 comprises a support surface 5 and a continuous surface 6 opposite it. In the embodiment shown here, the surface 6 comprises a first surface portion 15 and a second surface portion 16.The surface sections have a different inclination relative to the support surface 5, the first surface section 15 has an inclination Sol, the second surface section 16 has an inclination So2. The links 7, 8, 9 are connected to one another in a chain-like manner such that they form the surface 6 with the surface sections 15, 16. The surface section 15 has a constant inclination Sol of, for example, 1:100 (0.573°) relative to the support surface 5 over the length Lol, in this embodiment from the first end 3 of the device to a start of the second surface section 16, designated here by the reference numeral 14, which is formed here by a partial section 11 of the end link 9, so that the support surface 5 and the surface 6 converge at an acute angle to one another in the first surface section 15.

[0045] In the second surface section 16 of the surface 6, which in this embodiment is formed by a partial section 11 of the end member 9, the device 1 has a different, greater inclination So2 over a length Lo2 than the first surface section 15. As can be seen from Figures 3 and 4, this embodiment of the device 1 according to the invention can be used to produce a two-stage ramp 26, i.e., a ramp with two ramp sections 21, 22. The different inclinations Sol and So2 over the lengths Lol and Lo2 are symbolically represented by black triangles in the upper part of Figure 1.

[0046] The total length Lv of the device in the embodiment shown is, for example, 1540 mm, the length Lol of the first surface section 15 of the surface 6 with the first inclination So1 is, for example, 1340 mm, and the length of the second surface section 16 of the surface 6 with the second inclination So2 is, for example, 200 mm. The length Lvl, i.e. the length from the first end 3 of the device to the center point of the last screw connection 10 connecting the end member 9 to the adjacent intermediate member 7, is, for example, 1280 mm. The distance Lv2 (see right in Fig. 1 A), i.e. the distance between the center point of the last screw connection 10 and the start 14 of the second surface section 16 located towards the second end 4, is here, for example, 60 mm. The lengths Lgl and Lg2 indicated in Figure 1, which here are the distance from the first end 3 to the center point of the first screw connection 10 (Lgl) orThe distance between the centers of the screw connections 10 (Lg2) connecting the individual links 7, 9 is, for example, 80 mm. The height hl of the device at the first end 3 is, for example, 27 mm, and the heights h2 and h3 (see Fig. 1A) are, for example, 14 mm and 13.4 mm, respectively.

[0047] Figure 2 shows an enlarged view of the two end regions of the embodiment of a device 1 according to the invention shown in Figure 1. The central region of the device 1 is omitted. Figure 2A shows a longitudinal section of the device 1 along the dot-dash line in Figure 2B, and Figure 2B shows a top view. For a detailed description, please refer to Figure 1.

[0048] Figure 3 (see also Fig. 4 for details) shows a longitudinal section through a grooved rail 20 in the area of ​​the groove bottom 25. In the left area of ​​the figure, part of a first grooved rail section 21 with a first groove depth TI is shown, and in the right area of ​​the figure, part of a second grooved rail section 22 with a second groove depth T2. The grooved rail here comprises a deep groove on the left (with TI of, for example, 47 mm) and a shallow groove on the right (with T2 of, for example, 14 mm). Between the two grooved rail sections 21, 22, a ramp 26 is shown, which connects the groove bottoms 26 of the two grooved rail sections 21, 22. The total ramp length Lr can be, for example, 1540 mm. The ramp 26 here is two-stage and comprises two ramp sections 27, 28 with different inclinations, a first ramp section 27 with a length Lrl and an inclination Sri and a second ramp section 28 with a length Lr2 and an inclination Sr2.The inclination Sri of the first ramp section 27 can be, for example, 1:100, and the inclination Sr2 of the second ramp section 28 can be, for example, 10.50%. At the point where the two ramp sections 27, 28 merge, the grooved rail 20 has a groove depth T3 that is smaller than TI but greater than T2 and can be, for example, 26 mm. Since the lengths Lol and Lo2 of the device 1 are adapted to the lengths Lrl and Lr2 of the ramp sections 27, 28 to be produced, the lengths Lrl and Lr2 correspond to the lengths Lol and Lo2 specified above, i.e., 1340 mm (Lrl) and 200 mm (Lr2).

[0049] The embodiment of a device 1 according to the invention, shown in Figures 1 and 2, is arranged with its support surface 5 on the travel head 24 of the grooved rail 20. The device 1, which is shown hatched here, is arranged on the travel head 24 of the grooved rail 20 such that the first surface section 15 is arranged in the region of the first ramp section 27, and the second surface section 16 is arranged in the region of the second ramp section 28. The inclinations Sol, So2 of the two surface sections 15, 16 correspond respectively to the inclinations Sri, Sr2 of the two ramp sections 27, 28, i.e., the inclination Sol of the first surface section 15 corresponds to the inclination of the first ramp section 27 (Sri = Sol), and the inclination So2 of the second surface section 16 corresponds to the inclination of the second ramp section 28 (Sr2 = So2). The lengths of the sections also correspond to one another, i.e.the length Lol of the first surface section 15 corresponds to the length Lrl of the first ramp section 27, and the length Lo2 of the second surface section 16 corresponds to the length Lr2 of the second ramp section 28.

[0050] On the surface 6 of the device 1 according to the invention, a milling, welding, or grinding machine 100, shown here only very simply, is arranged, with a milling, welding, or grinding head 101 that is adjustable at least vertically by means of a handwheel 102. By means of wheels 103, the milling, welding, or grinding machine 100 can be moved along the surface 6 of the device 1 for producing the ramp 26. The milling, welding, or grinding head 101 can be adjusted to the height of the groove bottom 25 in the area of ​​the ramp 26 to be produced, ramp sections 27, 28, or the adjoining deep-groove or shallow-groove sections. A fixed vertical adjustment is sufficient, since the device can be moved along the inclined surface 6 of the device, and its inclination can thus be transferred to the ramp 26 to be produced.

[0051] Figure 4 shows an enlarged view of an arrangement 200 according to the invention, as also shown in Figure 3, without the milling, welding or grinding machine 100. For a more detailed description, reference is made to Figure 3.

[0052] Figure 5 shows a cross-section through a grooved rail 20 in the region of the first grooved rail section 21. Shown here is a grooved rail 20 (e.g. C-105) with a shallow groove of depth T2 of, for example, 14 mm. The device 1 according to the invention is arranged with its support surface 5 on the travel head 24 of the grooved rail 20. The device 1 is spaced apart in the transverse direction to its longitudinal direction 2 with its groove-side flank 17 from the travel head-side groove flank 29, for example by a distance x of 2 mm.
