Abstract
Description
Technical Field
[0001] The present invention relates to a method for material machining, post-processing, and / or treatment of rails laid in a roadbed, including grooved rails for railway vehicles for long-distance and short-distance traffic, including subway, surface railway, or industrial railways used as tools arranged on at least one vehicle. When a non-parallel alignment of the device with respect to each rail is detected using a control unit, In particular continuously, lateral distance measurements are carried out by a plurality of side-following elements that abut against different longitudinal portions of the same rail in the state of use, and the device is moved laterally depending on the lateral variance value of the distance measurements between different side-following elements assigned to the same rail. This device is moved translationally or displaced using at least one carrier for adjustment or change of the distance of each device from the assigned rail.
Background Art
[0002] Such a method is used, in particular, for machining and / or repairing laid rails, but also for measurement, in which case the device is arranged on a railway vehicle, and this railway vehicle moves along the rail to be machined throughout the machining, post-processing, or treatment.
[0003] Rather than following the existing inaccuracies and inhomogeneities in the rail, but rather correcting them, It is possible to carry out the machining significantly more precisely by means of side-following elements in such a way that the tracking of the device takes place in a plurality of degrees of freedom and, advantageously, also in separate delivery axes, and to achieve as a result an even and precise rail profile.
[0004] The objective is to ensure that the machine tools of the apparatus follow the rail profile as accurately as possible during machining, post-machining, and / or processing, in order to achieve optimal results with the least possible material removal, and with the best possible surface quality or dimensional stability, with respect to the longitudinal or transverse profile of the rail.
[0005] To avoid misalignment during machining and to ensure a consistent cutting depth, In material stripping processes, precise tool positioning and alignment relative to the rail should be accurately controlled, both vertically and horizontally, by using a small depth of cut.
[0006] In principle, lateral tracking elements for guiding machining tools, particularly milling tools, are already known in rail machining and belong to the known art. For this purpose, the relative position of the support for the machining tool is adjusted laterally with respect to the main extension of the rail by the lateral tracking elements.
[0007] The side-following element, however, cannot be brought into contact with the side of the rail below the axis of the machining tool or in a plane there, because there is not enough space available.
[0008] Accordingly, the side-following element abuts against the side at the front or rear of the machining tool, which induces only small, negligible machining errors at long wheelbases of vehicles, but conversely, induces problematic errors at short wheelbases of vehicles.
[0009] Position-adjustable guide elements for forcibly guiding a machining tool to correct its direction or adjust its position are known, for example, from Patent Documents 1 and 2.
[0010] In Patent Document 3, for a side-following device on a laid rail, contact elements for the inside of the rail head and for the inside of the built-in structure within the track passage are configured to reciprocate and to be variable in width.
[0011] Patent Document 4 provides a known apparatus having an end-face milling machine for processing rails, in which multiple guide rollers are used, and these guide rollers are rotatable about a vertical axis. The multiple guide rollers are mounted on a slider and are in contact with both sides of the rail.
[0012] Furthermore, suitable measuring means for post-adjustment of machining tools, such as contact elements or non-contact measuring elements, are disclosed in Patent Document 5 or Patent Document 6.
[0013] In a rail processing apparatus according to Patent Document 7, a side-tracing device having two measuring points offset in the longitudinal direction is rotated until the two sequentially positioned measuring points obtain the same measurement result with respect to the inner edge of the rail. The side-tracing device ensures the precise position of the cross slider of the processing tool relative to the inner edge of the rail. This is related to the time-consuming kinematic conditions, and these kinematic conditions, in particular, the series combination of multiple pivot axes, the Z-axis and X-axis, and a carrier configured as a cross table for introducing different translational movements, practically induce significant tolerances. In particular, such mobility with multiple degrees of freedom, as a result of lever action, practically leads to insufficient rigidity with respect to the forces generated during machining and processing. In such cases, the resulting forces are practically difficult to control and induce the influence of undesirable tolerances.
[0014] From Patent Document 8, in addition, one apparatus can be read, which is used for reshaping at least the running surface of the rail by outer perimeter milling. The rail profile milling machine is intended to produce the desired profile in a single outer perimeter milling step. Additionally, the apparatus is equipped with a polishing device, which enables the subsequent polishing of the running surface. In this case, one device is provided, which generates relative movement between the rail and the polishing disc. The axis of the polishing disc is bearing in one direction, which deviates from a plane set perpendicular to the longitudinal direction of the rail. At that angle, the polishing disc is aligned with the rail; the angle of the polishing disc depends, in this case, on the condition of the rail prior to polishing.
[0015] Patent Document 9 describes an apparatus for processing the running surface of a rail by outer perimeter polishing. This apparatus includes a polishing frame, which is adjustable in position relative to the running surface of the rail and is movable along the rail. The polishing frame comprises at least three freely rotatably supported polishing bodies for outer perimeter polishing, the rotational axes of these polishing bodies forming an acute angle with respect to the longitudinal direction of the rail. The first polishing body forms an acute angle with respect to the longitudinal direction of the rail with respect to its rotational axis, and this acute angle is different in notation from that of the second polishing body. The arrangement of the polishing bodies is such that the sum of the lateral forces generated during the movement of the polishing frame along the rail—forces perpendicular to the longitudinal direction of the rail and perpendicular to the position adjustment direction that is perpendicular to the rotation axis of all polishing bodies—is essentially zero, and The polishing frame, perpendicular to the direction of position adjustment, is selected such that the resulting rotational torque is also essentially zero.

Summary of the Invention
Problems to be Solved by the Invention
[0017] The problem underlying the present invention is thus to provide a simple possibility for compensating for the displacement of the device from an alignment parallel to each rail, without such a complex compensation kinematic situation being associated with a plurality of degrees of freedom for the restoration of the alignment parallel to the rail of the device. In particular, the support arm pivotable about an axis in the vertical direction for the support of the device should be omitted.
Means for Solving the Problems
[0018] This problem is solved according to the present invention by a method having the features of claim 1. Further configurations of the present invention can be seen from the dependent claims.
Advantages of the Invention
[0019] The present invention therefore intends a method in which processing, post-processing, and / or treatment are performed. Based on the detected lateral difference value of the side-following element, the device is aligned parallel to the rail with respect to the first working position as the initial position, and then performed or continued at the changed or displaced working position of the device. In this alignment, the device is moved exclusively translationally by a difference in value relative to the first working position, and therefore, at the first working position, the device occupies an alignment that has an angle less than or greater than 90° with respect to the alignment of the device. In that case, the difference value is determined and adjusted depending on the angle of deviation, or the lateral difference value, and other parameters of the device, particularly the length and contour of the contact surface of the device with the rail. In that case, the present invention allows for the restoration of the original working position. This approach starts from the understanding that, as known from prior art, only the differential value from the rail, adapted to each device, is adjusted by the combined position adjustment of a swivel arm and the linked translational movement of the device using a carrier, and is particularly excluded when it is being enlarged or reduced. Indeed, in that case, the device occupies an offset or inclined position where, as a result of the altered alignment state, it forms an acute or obtuse angle with respect to the alignment state of the device in its initial position. However, the machining or processing of the horizontal region of the rail head profile, It was found that the method is either independent of the tilt position or depends on the tilt position to a negligible degree. Machining or processing of non-horizontal regions on the sides can be compensated for by the difference value and, therefore, can be continued without correction of the angular position. In practice, the angle of inclination does not exceed approximately ±5°, and is practically approximately ±2°, resulting in a situation where a processing or treatment surface precedes or follows, which can also be called dragging or inserting processing or treatment (schleppende oder stechende Bearbeitung bzw. Behandlung). In other words, the device already operates in front of or behind the horizontal surface on the rail head profile as a result of the inclination position with respect to this surface. To avoid excessive scraping of the convex rail head profile caused by this pre-cutting or post-cutting engagement, the difference value is adjusted in proportion to the initial position, i.e., the device is moved laterally or centrally, and for the above, practically speaking, translational kinematic conditions in particular are adapted in the most optimal way.
[0020] In accordance with the present invention, the initial position should be understood as the alignment and spacing of the device on the rails along a straight track, where the vehicle is in a centered and normal position on the straight rail section and is not in a state of diagonal travel (Spiessgang). If a vehicle is not aligned with the rails and is instead positioned with a misalignment, maintaining its initial position throughout its journey may require translational movement of the equipment. This new working position, which is shifted from the initial position, is intended in accordance with the present invention when the vehicle and the associated equipment are positioned on the rails at an inclination, i.e., non-parallel, in particular, i.e., in a state of diagonal travel (Spiessgang), in a chordal position (Sehnenstellung) within a track curve, or within the area of a switch.
[0021] The present invention, in conjunction with this, When the length or profile of the contact surface of the device with the rail is determined and adapted based on the measured difference values of the side-following device, or the angle of inclination derived from these measured difference values, and other parameters of the device, particularly the engagement length or processing length of the device, Restoring the initial position is not necessary at such an inclined position. They are taking advantage of that.
[0022] Of course, individual processing should not be excluded, but this method is not limited to the processing or treatment of a single track rail within the roadbed. Particularly advantageous is that at least one device is assigned to a first rail, and at least one yet another device is assigned to a second rail, in which case the devices assigned to different rails are each moved centrally or laterally to at least one working position that is offset from a first working position as an initial position. Accordingly, unlike in the prior art in which both devices are moved together for both rails in order to reduce the distance to one of the rails and increase the distance from the other rail for the purpose of returning the initial position to its original state, In accordance with the present invention, each device assigned to a different rail moves inward or outward, thereby adjusting the relative position with respect to the rail, which is shifted from its initial position, as a difference value.
[0023] In that case, it is possible that the translational movement of the device is intended to be kinematically linked. Furthermore, the movement can also be synchronized by a control program.
[0024] Such connections may be useful, in particular, when the measurement of one rail is lacking a lateral tracking device, and when the assistance of the measurement of the other rail extending parallel within tolerance limits, particularly within the area of the switch, based on, for example, the loss or condition of the rail. This allows, in the event of interruption, or for the purpose of inspecting the position detection of the side-following element of one rail, the measurement of the side-following element of the other rail to be used to adjust the changed working position.
[0025] Another, particularly advantageous embodiment of the method according to the present invention is achieved when the curvature radius of the rail is calculated based on the detected measurements of a side-following device assigned to one of the rails. For this purpose, a control unit is used to inspect the alignment of the vehicle on the rails and the alignment of the equipment relative to the rails by comparing the ground radius calculated for each rail, taking into account the wheel track, and in some cases, any possible machining errors are detected in a timely manner. In that case, if the deviation is found to be outside the predetermined tolerance range, then, with prior consideration, other working positions with increased difference values may be set.
[0026] This method, like scraping with geometrically determined or undetermined cutting edges, is used for surface hardening or smoothing, or for measurement. Particularly advantageous is that the material stripping process is carried out by the apparatus with at least one rotating milling tool and / or grinding tool, wherein the axis of the milling tool is basically horizontal and, in its initial position, centered within the cross-section of the rail. Furthermore, at a different working position, the rotation axis of the milling tool forms an acute or obtuse angle with the cross-section of the rail.
[0027] The apparatus may be configured for machining or processing a vertical or horizontally inclined area on the side of the rail head profile. Advantageously, rotating tools are used during machining, post-machining, and / or processing. With at least one first part, with respect to the running surface of the rail, Furthermore, at least one other portion abuts against the side of the rail head profile.
[0028] Each side-following device can use a probe to make contact with the central side of the rail head profile. Other, particularly practically adapted embodiments of the present invention, also achieve the interval measurement using a side-following element by being performed non-contact.
[0029] Advantageously, one or more side-following elements assigned to the rail, The milling tool's axis of rotation determines the position of the cross-section, both in front of and behind the initial position, and is advantageously positioned at different intervals along the longitudinal direction of the rail.
[0030] In an embodiment of the present invention that promises further results, the working positions of various devices assigned to opposing rails are adjusted in a synchronized manner using a control unit.
[0031] The present invention allows for various embodiments. For further clarification of the fundamental principles of the present invention, one embodiment among the embodiments is illustrated in the figures and described below. [Brief explanation of the drawing]
[0032] [Figure 1] This is a front view of a machine for milling rails. [Figure 2] This is a perspective view of the apparatus shown in Figure 1. [Figure 3]This is a plan view of the device in an orientation that is not parallel to the rails and is inclined outward in the direction of movement. [Figure 4] This is a plan view of the device in an orientation that is not parallel to the rails and is inclined inward in the direction of movement. [Figure 5] This is a plan view of the rail having a pre-cut surface, corresponding to the inclined alignment shown in Figure 3. [Figure 6] Figures 1 and 2 show a plan view of a rail having a neutral machined surface corresponding to parallel alignment. [Figure 7] This is a plan view of a rail having a post-machined surface corresponding to the inclined alignment shown in Figure 4. [Modes for carrying out the invention]
[0033] A method according to the present invention for material removal or post-processing of rails 1 laid within a roadbed, using an apparatus 3 equipped with a milling tool 2, will be described in more detail below with reference to Figures 1 to 7. Device 3 is positioned on a railway vehicle not shown, and as a result, the machining of rail 1 is performed while it is moving, and therefore, information on the alignment and position of the milling tool 2 relative to rail 1 is of important significance for the machining result.
[0034] For this purpose, in a self-known manner, The lateral difference value is determined using a plurality of side-following elements 15 and 16 arranged sequentially in the longitudinal direction of the rail, which abut against the side surface 4 of the rail head profile 5 with a spacing a1 in the direction of movement V at the front of the device 3, and abut against the rear of the device 3 with a larger spacing a2 in the direction of movement V. From these lateral difference values, the amount and direction of the recognizable tilt position in Figures 3 and 4 can be derived using a control unit not shown.
[0035] In Figures 1 and 2, the neutral position of the milling tool 2, which is aligned parallel to the rail 1, can be recognized. At this time, the rotation axis 6 of the milling tool 2 is located within the cross-section of the rail 1 and, consequently, at an angle of 90° with respect to the longitudinal axis 7 of the rail.
[0036] Figures 3 and 4 show the inclined positions of the milling tool 2, which are oriented by a 2° deviation from a plane parallel to the longitudinal axis 7 of the rail. Specifically, in the direction of vehicle movement V, the inclined positions of the milling tool 2 have an angle α of 92° outward or to the side with respect to the center of the roadbed in Figure 3, and an angle β of 88° inward or towards the center in Figure 4.
[0037] It is easy to understand that the engagement of the contoured milling tool 2 changes depending on this inclined position. The first peripheral portion 8 of the milling tool 2 shown in Figure 1, which is used for machining the horizontal running surface 9 of the rail head profile 5 of rail 1, achieves a constant scraping result, whereas, The inclination position of the contoured second portion 10 of the milling tool 2, which is used to machine the side surface 4 of the rail head profile 5, which is inclined horizontally and curved in a convex shape, requires a lateral spacing adjustment to achieve a consistent machining result. This is because, depending on the inclination position of the milling tool, otherwise, without appropriate countermeasures, an undesirable increase or decrease in material removal on the side surface 4 will occur within this second portion 10.
[0038] In accordance with the present invention, this additional scraping does not remove the inclined position, but rather, The milling tool 2 is prevented from moving to a second working position by translational movement in a direction 11 parallel to the rotation axis 6, by a predetermined difference value D derived from the measurement values detected by the side tracing device, as controlled by the control unit. This difference value D is clearly shown in Figures 3 and 4 in relation to the milling tool 2, which is only symbolically illustrated, in an aligned state parallel to the rail, and it should be emphasized that this does not release or reduce the inclined position of the milling tool 2. The required difference value D is derived from the calculated angles α and β of each displacement and various parameters of the milling tool 2.
[0039] Figures 5 and 7 clearly illustrate the effect of the inclination position on the work results. As shown in the inclined positions in Figures 3 and 4, the abrasion and size of the machined surface 12 on the running surface 9, which is machined by the first peripheral portion 8 of the milling tool 2, remain at least essentially unchanged.
[0040] In relation to the above, as can be seen in Figure 5, based on the positive inclination position shown in Figure 3, the engagement of part 10 of the milling tool 2 results in a situation where the machined surface 13 is cut in the direction of movement V, and this engagement precedes the neutral position of the milling tool 2 shown in Figure 6. As a result of the set difference value D, however, the scraping and the contour of this scraping remain unchanged when compared to the neutral position of the milling tool 2.
[0041] In a similar manner, as can be seen in Figure 7, based on the negative inclination position shown in Figure 4, the engagement of part 10 of the milling tool 2 results in a machined surface 14 being cut in the direction of movement V, and this engagement is retrograde to the neutral position of the milling tool 2 shown in Figure 6. In this case as well, the scraping on rail 1, and the outline of this scraping, remain unchanged when compared to the neutral position of milling tool 2, as a result of the set difference value D.
[0042] Therefore, according to the present invention, the deviation of the rotation axis 6 from the cross-section of the rail 1 is detected. While the tilt position is certainly not corrected, rather, The action of the machined surfaces 13 and 14 to be cut before or after is adapted to the initial position or neutral position parallel to the rail by the translational movement of the milling tool 2, which is inclined and upright, inward or outward, by the difference value D of the milling tool 2. Therefore, the machining process continues in this altered working position. This is continuously inspected and, if necessary, corrected based on the measurements of the side-following elements 15 and 16.
