Definitions

  • the invention relates to a device for monitoring the distance between the end faces of rails, for example in the event of dilatation impacts or supporting structures, in which the rails are subjected to multiple axes.
  • Rails and tracks are usually laid on a substructure, for example on sleepers. In the course of the routing, it is sometimes necessary to provide dilatation surges in order to be able to accommodate displacements of rails in their longitudinal direction without deformation of the rails transverse to their longitudinal direction. With such rail joints, the rails are only subjected to a sliding movement in their longitudinal direction with a correspondingly stable substructure, so that the exact spacing of the rails from one another in the area of dilation joints is readily possible.
  • Tracks which are arranged on substructures, which are loaded with multiple axes, cannot be easily monitored with conventional measuring devices.
  • deviations may also occur transversely to the longitudinal direction of the rails, which should be detected in a suitable manner. Irrespective of the detection of further deviations, however, such additional movements of the substructure significantly reduce the measuring accuracy.
  • the distance is to be recorded analogously with inductive proximity sensors, pivoting of the rails would result in the measuring surface being inclined relative to the sensor, which leads to incorrect displays and does not allow precise statements to be made.
  • Precise recording is especially important for bridges and more or less floating floors the exact length of the dilatation joint, irrespective of any additional deviations that may be recorded, is essential in order to be able to correctly monitor the safety of the passability of the tracks.
  • the invention now aims to provide a device of the type mentioned, in which substructures can be used for the laying of the rails, which are themselves multi-axis stressed and can therefore cause additional relative displacements of the rails without the measuring accuracy for the Distance in the dilation joint suffers.
  • the inventive design of the device of the type mentioned essentially consists in that the rail (s) is (are) connected to at least one plate extending transversely to the longitudinal direction of the rail or a damping element that the axis (s) of the (the) measuring sensor (s) is (are) normally oriented on the plate (s) and that the rail (s) near the attachment points for the plate (s) is slidably supported and secured against pivoting from the direction of movement to be measured ).
  • one of the two rails of the rail joint can readily be rigid and fixed on a largely immovable substructure, whereas the second rail can be displaceable in the longitudinal direction of the rail in the event of signs of dilatation.
  • the movable rail as proposed according to the invention, is now connected to a plate extending transversely to its longitudinal direction, an additional lateral displacement of the substructure or of the supporting structure can lead to a bending of the rail, which in itself does not yet definitely mean operational safety would endanger, but would significantly affect the measured values of a measuring sensor, in particular an inductive measuring sensor.
  • the sensors must be provided at a lateral distance from the rail and the size must be correspondingly large lateral extension of the plates extending transversely to the longitudinal direction of the rails, which interact with these sensors to determine the correct distance. Due to the relatively large lever arm, pivoting the rails would result in these plates being pivoted significantly out of their normal position required for the correct measurement, so that exact measured values can no longer be achieved.
  • the axis (s) of the measuring sensor or sensors is (are) normally oriented on the plate, and in order to ensure this normal orientation of the axes of the measuring sensor or sensors, the rail is clamped according to the invention in such a way that which releases the direction of movement to be measured, but certainly prevents movements transverse to this direction of movement in order to prevent the plates connected to the rails from sloping.
  • a corresponding slide bearing is provided near the fastening points for the plates or the damping elements, which is intended to reliably prevent unauthorized pivoting.
  • the design is such that the support is formed by rollers supported on the rail transversely to the direction of movement to be measured, such a roller bearing advantageously being formed by a plurality of rollers which are combined with a common carrier, so that a sufficiently large support length is guaranteed, which prevents the rail from pivoting in the area of the measuring sensors with certainty.
  • the design is such that the rollers are supported against a measuring console on which the measuring sensor (s) is / are arranged in a stationary manner, the rollers with a common support between the corresponding abutment surfaces on the rail and console can be inserted and the rolling path of the rollers in the longitudinal direction of the rails can be limited by appropriate stops.
  • the path over which the rollers can move freely in the longitudinal direction of the rails must be should be chosen sufficiently large so that the dilation, which takes place in the direction of the direction of movement to be measured, is not impeded and actually enables exact statements to be made.
  • inductive analog proximity sensors are preferably used in the device according to the invention.
  • Such inductive proximity sensors must be shielded and wired accordingly to keep them free from the influence of stray fields, especially when using electric locomotives. This usually results in a more or less large distance from the rails, which in turn means that the damping element, which interacts with the sensors, must be dimensioned correspondingly larger.
  • Such measuring sensors generally have a precisely defined measuring range over which the measuring characteristic behaves linearly. Such measurements are therefore preferably used in their linear characteristic range, and in the case of large possible shifts in the measurement direction, it is not readily possible to correctly detect the entire shift with such a measurement sensor.
  • the arrangement is therefore advantageously made in the context of the device according to the invention such that two measuring sensors are arranged coaxially at a distance from one another which is greater than the length of the linear characteristic range of the measuring sensors, and that two mutually parallel plates are arranged at a distance from one another between the measuring sensors are.
  • two measuring sensors at a distance from one another which is greater than the length of the linear characteristic range
  • a correspondingly larger displacement path can be exactly detected by two sensors, each working in their linear characteristic range.
  • the measure of arranging the two sensors at a distance from one another can be used to select this distance so large that the two sensors do not influence one another, so that stray fields from one sensor do not measure the other sensor affect.
  • two mutually parallel plates are arranged at a distance from one another between the measuring sensors, this distance of the two plates from one another being so large that it is actually ensured that the two measuring sensors do not influence one another in any way.
  • the training is advantageously carried out in such a way that separate sensors are provided for relative displacements of the supporting structure and any displacements of the rails transverse to the measuring direction of movement. In this way it is ensured that the measured values for the orientation of the rails and the spacing of the rails required for safe operation are actually recorded independently of the movements of the supporting structure linked to these relative movements via complex relationships.
  • FIG. 1 shows a schematic illustration of a device for monitoring dilatation devices, in addition to a device for monitoring the distance between the end faces of rails, relative displacements of a supporting structure can also be monitored
  • FIG. 2 shows the device according to the invention for monitoring the distance in an enlarged view the end faces of rails according to Fig.1.
  • FIG. 1 shows two rails 1 and 2, the end faces 3 and 4 of which are spaced apart in the region of a dilation joint.
  • the rails are mounted on a supporting structure, which is multi-axis stressed and should be used to correctly determine the The distance between the end faces 3 and 4 of the rails 1 and 2 can only be movable in their longitudinal direction, as will be shown in more detail in FIG.
  • the rail 1 is rigidly clamped and the movable rail 2 is connected to a measuring console 5 with plates or damping elements 6 extending transversely to the longitudinal direction of the rail.
  • Measuring transducers 7 cooperate with the plates or damping elements 6, the axes 8 of which are normally oriented on the surface of the plates 6.
  • the correct values are obtained by combining the measured values obtained from the two sensors 7 Distance between the end faces 3 and 4 determined. Since the maximum distance of the end faces 3 and 4 to be measured from one another generally extends beyond a region of a transducer or measuring sensor 7 that can be detected or at least has a linear characteristic curve, the parallel plates or damping elements 6 are arranged at a distance from one another between the measuring sensors 7, whereby the two measuring sensors 7 are arranged at a distance from one another which is greater than the length of the linear characteristic range of the individual measuring sensors 7.
  • the measured values obtained from the sensors 7 are fed to a central control and evaluation unit 11 which, in addition to a warning device 12, interacts with a printer 13, a data display device 14 and further peripheral units schematically indicated with 15.
  • the deflection of the rails is monitored in a region of the rails which is remote from the end faces.
  • a measuring plate 16 is arranged on a rail, which cooperates with a further sensor 17, a corresponding signal from the sensor 17 being fed to the central evaluation unit 11 when the rail is displaced in the direction of the double arrow 18.
  • 19 connecting rods are indicated between the rails designated 20.
  • the support of a rail transverse to its longitudinal direction is particularly important when measuring the spacing of the end faces of two adjacent rails if the rails are stressed in multiple axes by their mounting on a supporting structure.
  • a monitoring of the relative displacements of a supporting structure is also shown schematically in FIG. 1, four supporting elements 21 which are spaced apart being indicated.
  • One of the supporting structures is connected to a measuring console 22, which, according to the number of displacements or directions of movement to be measured, has damping elements 23 which cooperate with a plurality of sensors 24, the axes of the individual sensors 24 in turn being arranged normally on the damping elements .
  • the relative position of the individual structural elements 21 can be determined by combining the data obtained from the individual sensors 24.
  • the measured values obtained from the mutual spacing or the deflection of the rails are linked, a complete picture can be obtained of the orientation of the rails and the stress on them.
  • FIG. 2 To measure the Distance between the end faces 3 and 4 of two rails 1 and 2 is in turn connected to a measuring console 5 with the rail 2 and has plates or damping elements 6 which extend transversely to the longitudinal direction of the rail in which the distance is to be measured. Measuring transducers or measuring sensors 7 are in turn arranged with their axes 8 normally on the plates 6. In order to prevent the rail 2 from pivoting transversely to the longitudinal direction of the rail, rollers 10 are again provided, which cooperate with the rail web of the rail 2. The rail 1 should in turn be rigidly clamped.
  • rollers 10 of the slide bearing of the rail 2 are fixed on a further measuring console 26, on which the sensors 7 are also arranged in a fixed manner in a manner not shown, the console 26 in a manner not shown on which a rigid bearing surface for the rail 1 forming substructure.
