Definitions
- the invention relates to a method and a device for the controlled page copy of a device unit for analysis, for material removal or material application on laid rails.
- the method and the device for tracking the device unit is used for traversing rail gaps such as rail joints, points and crossover areas, but also railroad crossings and grooved rails.
- the goal is a device unit tracked as exactly as possible on the rail profile. Such a method is described in claim 1 and dependent claims 2-12, the apparatus in claim 13 and the further dependent claims 14-28.
- Rail processing for laid railway or tram rails is as described e.g. mentioned in patent EP0952255A1.
- the objectives are defined in all rail machining so that at the same time a maximum removal of flaws or cracks depending on the rail condition at the lowest possible material removal, and the best possible surface quality or dimensional accuracy in relation to the longitudinal or transverse profile can be achieved. Grinding applications here are more in the range of low removal rates, milling more in the range of larger delivery depths represented. Furthermore, planing applications for reprofiling rails are known.
- the different track width which is also subject to tolerances, should be considered as a source of error. These deviations can each amount up to a few millimeters and are not acceptable.
- the processing of the rail should be aligned according to the relevant inner edge or the respective track channel of the rail.
- the aim of the present invention is therefore to solve these disadvantages of the existing systems and the associated problems in rail processing and / or rail analysis and to provide a method and an apparatus which optimizes rail processing and / or rail evaluation by a controlled tracking of respective device by means of controlled page copying or controlled page copying in particular by a timely recognition of the rail gap and safe reconnecting after passing through the inclusion of the Radlenker and wing or tongue rail of each track channel in the control.
- At least one side-facing element is arranged in each case on the inside of the respective rail per rail track.
- the page-copy elements are assigned to the rail side surfaces or geometry-part regions of the rail inside and control the respective device associated with the rail unit independently.
- the button or sensor can be fixedly connected to the device unit. In practice, however, a measurement of the travels of the buttons or sensors has been found to be more useful, as programmatically low irregularities are easier to process and tracking the device unit if not desired or useful, can be easily prevented.
- the position detection and tracking via non-contact systems such as optical detection using a camera, laser or capacitive or inductive pickups is possible. Due to the size of larger device units is also also known that due to cramped space or Störgeometrien, such as when determining the rail position, programmatically both page settings depending on each other on both processing units can simultaneously influence.
- the device of the opposite rail track performs independently of the first rail track depending on the requirements of analog or different processes by, for example, at the time of a derailment to determine the rail position a programmatic coupling of both device units of both rail tracks can be done.
- the method according to the invention extends the page-copy elements described above by incorporating the further information from the track channel into the controller.
- This information can be used by the Radlenker, a wing or tongue rail, but also at level crossings or grooved rails for more precise positioning of device units. In this case, only the information from the assigned track channel of the rail to be processed and / or analyzed is primarily obtained.
- the method according to the invention by the information of the track channel also automatically determine the beginning of a switch by the detection of the tongue area, by the tongue rail or rail tongue, the sake of simplicity in sequence as a tongue rail, which is located at a distance from the rail.
- FIG. 1 shows a schematic arrangement of the copy elements during a passage through the passage according to an embodiment of the invention
- Figure 2 is a schematic arrangement of the copying elements during a passage through the passage in a second embodiment according to the invention
- Figure 3 is a schematic side view of a rail head with a hired copy and representation of the y-axis
- Figure 4 is a schematic side view of a rail head and a Radlenkers, wherein the copying element is employed on the Radlenker. It designates:
- feeler elements but also non-contact sensors which mechanically link the position information or forward it electronically to a processing tool, a setting device, an analysis device or a controller.
- the respective position of the sokopierelements (20) can be seen relative to the rail (10) in the y direction.
- a deviation results from a movement in the y-direction during a defined feed of the rail vehicle, which lies outside a certain range of a possible rail curve. If this deviation in the y direction lies above a certain path to be defined, this is referred to as the predefined limit of intervention which can trigger a reaction.
- the page copy serves the device unit for exact positioning to the rail (10).
- This device unit may be an analysis unit for determining the quality of the rail (10), in particular a camera for image acquisition, a sensor for detecting cracks, as well as a sensor for determining the surface roughness and / or ripple.
- the device unit may also be a material application device. Under material order are, for example, welding devices, but also to understand other material application devices. Furthermore, the device unit may be a material removal device. In particular, processing methods such as grinding, milling and planing for material removal are mentioned here.
- Under track channel (12) is the space from the rail side contour in the direction of track center to see. This track channel (12) can be seen in particular in Figures 3 and 4.
- this track channel (12) which extends in a width of up to 150 mm from the rail (10) to the track center at turnouts and crossings, as well as in railway overpasses interesting because here additionally by occurring wing or tongue rails (31, 33), Radlenker (30) and other structural elements information about the track condition can be made.
- the side-copy element (20) in the direction of the rail inner edge (11) is designed such that both the inside of the rail (10) to be processed and the inside of the track channel (12) of the rail side (30th) associated with the rail (10) ) or wing rail side (31), ie in the direction of track center, can be scanned. If there is an increased deviation when passing through the rail track (10) (reaching a defined intervention limit), this is due to an irregularity in the rail track (10). Thus, the side (20) at a rail gap lead to an increased measurement deflection and then deflected in the opposite direction to the track center out that it comes on the Radlenkerseite (30) or wing rail side (31) to the plant. Thus, the page overlay (20) is protected from the next impurity such as the frog tip (32).
- the page copy (20) If there is no installation of the page copy (20) and the page copy (20) is deflected to a defined end position in the direction of track center, it is in this case when crossing the rail gap to no track channel crossing as the heart (32) of a switch or for example, the single-heart piece (32) or double-heart piece of an intersection, but due to a failure to reach a run-up contour to a driving over a rail joint gap.
- the page copy (20) can be re-applied to the rail (10).
- the page copy (20) Upon reaching a wing rail (31) or a Radlenkers (30), the page copy (20) each remain up to a predefined limit of engagement at the Spurkanalinnenseite (13).
- the second limit of engagement that is, the side coping at the end of the wing rail (31) moves further to the track center, the rail break has been successfully overrun and thus the side coping (20) can again be securely applied to the inside of the rail (1).
- this position of maximum deflection towards the track center occurs a second time in relation to a defined trajectory resulting from the track and intersection, the double-frog area has just been left behind.
- the page copy (20) is immersed in the track area of the counter track. A provision can also be made again. This is represented by another switchover.
- the page copy (20) is now back to the inside of the rail to be machined (1 1).
- the device can continue to stand in the engaged position, ie in function, or in a retracted position without engagement with the rail (10).
- the track channel (12) is specified at Radlenkern (30) at standard gauge with 38mm, a constructive design of a mechanical Sokopleitersgleitelements (20) with the necessary lateral clearance to a maximum width of about 30mm as appropriate to consider.
- This sliding element (20) can be used separately or in one piece for engagement with the rail inner edge (1 1) and track channel inner edge of the Radlenkers (13) or the wing rail (31).
- the copying element (20) can also be designed as a roll.
- the side-copy element (20) is designed such that the adjustment to the rail head inner side (11) and the adjustment to the inside of the track channel (12) of the wheel link (30) or the wing or tongue rail (31, 33) is represented by two separate or combined sensing elements (20).
- the inner button (20) which is in the undisturbed track (10) without function, deflected in the direction of the associated rail inner edge (1 1). This is to be expected with the passage, for example, a Radlenkers (30) or a wing or tongue rail (31, 33).
- the feeler element (20) on the wheel guide (30) or on the wing rail (31) is deflected again to a predefined dimension in the direction of the track center, the frog area (32) is left safely again and the side lining (20) can be returned to the Inside (1 1) to be processed rail (10) are applied.
- the page copy (20) on the Radlenker (30) and the wing rail (31) is brought into a distant retreat position and only after a traverse of the rail vehicle of about 500 mm employed again.
- the sensing elements (20) on both the rail (10) and the Radlenker (30) or wing or tongue rail (31, 33) are arranged obliquely and also to scan or record a transition region between the side surface and the radius of the rail head profile.
- the sensing elements (20) have in this embodiment only a sliding area and can back in rail gaps in a secured retreat position. In the withdrawn state, the respective adjacent button (20) takes control of the determined measurement results.
- Such an element (20) can scan both sides simultaneously or optically detect and is variable in width.
- the variable width causes, for example in a Radlenker (30), the first engagement takes place in the conical inlet zone, then the width decreases according to the track channel width and the width increases again at the conical outlet.
- the method according to the invention does not require any change to a track channel foreign, e.g. Outside of the rail (10) or opposite rail (10) take place. Furthermore, however, a tongue region (33) of a switch can also be detected automatically and corresponding measures can be initiated on the device.
- the method already described is extended to the effect that an approximate position relative to the rail (0) can also be represented in the region of rail interruptions, in particular in the case of frogs (32).
- This is inventively achieved so that at least two side-copy elements (20) based on the same rail (10) are executed one behind the other.
- the elements of two side coverings bear against the same inner rail edge (11).
- the copy elements (20) can be designed again as described above.
- the positions of the scanning elements (20) in the y-direction are determined on the basis of the actual positions and continuously compared.
- a predefined intervention window can be used to detect immersion in a rail gap. This intervention window results from a corresponding deviation of the y-position at a defined right of way.
- the previously described vertically arranged sensors or buttons for detecting the rail gaps can also be used here.
- the successively arranged side coverings are arranged at a distance from each other so that a maximum gap without loss of the rail inner edge (1 1) can be easily passed over. If a pushbutton (20) is in the position of a rail gap, the control of the device is switched over to the further pushbutton (20) remaining on the inner rail edge (11). Only when the first copy element (20) has been reset to the rail inner edge (1 1), the measurement signal is used again by this for the controller. By detecting the frog tip (32) by the described additional vertical button or sensors can be done early recovery of the first page copy (20). As a result, the distance between the successively arranged side coverings (20) slightly above the max. occurring gap spacing can be selected. This gap is usually at max. 1600 mm.
- three or more side-facing elements (20) are arranged one behind the other per rail track (10) and relative to the same rail inner edge (11).
- the execution and the sequence is carried out as in the variants described above, wherein the page copy (20), which performs the actual position control of the device unit, at least one page copy (20) before and at least one further page copy (20) is connected downstream.
- the page copy (20) which performs the actual position control of the device unit
- at least one page copy (20) before and at least one further page copy (20) is connected downstream.
