Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the cord of a section of track which is, in the known machine, formed by a laser beam in a fan or scanning in a vertical plane.
  • This cord extends between the emitter which is on the director rail or axis of the track and the point of intersection of the beam with the director rail or axis of the track.
  • the measurement interval for which the transmitter remains fixed while the machine approaches it step by step is identical to the rope, i.e. the initial measurement in a measurement interval begins at the point of intersection of the beam with the director rail or track axis.
  • This measurement interval corresponding to the rope is limited in length by the condition that the largest arrow must not be greater than the possibility of lateral movement of the receiver on the machine, because this receiver must adjust to the point of impact of the beam, the value of the possible lateral displacement out of the chassis of the machine being generally limited by the prohibition to enter the gauge of the parallel rail so as not to hinder traffic on this rail.
  • the receivers for shifting and leveling are installed on a front measurement carriage which defines the front point of a relative measurement base constituted by a reference line; the position of this reference line is used to determine, by means of the adjustment data of these receivers, the correction values of the channel which is directly displaced under the reference line, at the working point which is behind said point before. Under these conditions, the machine operator only knows the correction values when the track is moving, and an obstacle may prevent any movement or require a specific movement of the track.
  • the present invention provides a device for controlling a machine for repairing a track which avoids the aforementioned drawbacks.
  • the device according to the invention is characterized by the features of claim 1.
  • Figure 1 shows, schematically in side view, the laser transmitter with the receiver for leveling and, in phantom, the horizontal beam, and in dotted lines the vertical beam.
  • Figure 2 shows the same view as Figure 1, but in plan, with the receiver for shifting, the vertical beam being drawn in dashed lines while the horizontal beam is drawn in dotted lines.
  • FIG. 3 schematically represents the laser receiver either for shifting or for leveling with the adjusted laser beam.
  • FIG. 4 schematically represents a transverse view of the track with the leveling and shifting receivers.
  • Figure 5 is a schematic perspective view illustrating the principle of the device with the two beams and the two receivers.
  • FIG. 6 schematically represents a top view, on a curved section of the track, the deviation from the theoretical curve indicated in phantom has been exaggerated for better understanding, and on which several points have been represented to illustrate the shifting.
  • Figure 7 shows an enlarged partial view of the curved section of the track, according to Figure 6, at a working place.
  • Figures 8, 8a, 8b show block diagrams of the device for three different methods of controlling channel corrections.
  • Figure 9 shows, schematically, a cross section of the track at the level of the receiver for shifting, showing the deflection calculation system, and below, the path traveled by this receiver on its support during the measurements at the different measurement points .
  • FIG. 10 schematically represents a top view of a preferred embodiment of the device according to the invention.
  • Figures 11 and 11a show schematically a transverse and lateral view of an arrangement preferred of the two receivers.
  • FIGS. 1 to 5 The operating principle of a machine making it possible to carry out the process according to the invention will firstly be described by means of FIGS. 1 to 5 for its application to the straight sections of the rails, with a view to explaining the shifting and leveling.
  • a machine is moreover described in patent EP No. 90098.
  • a single laser transmitter 1 is therefore provided, placed in front of a leveling and ripping machine on a railway track, advancing along the arrow (fig. . 1) and shown diagrammatically in the drawings by a main chassis 2.
  • This transmitter 1 is suitable for emitting a fan-shaped or sweeping beam either horizontally for leveling (beam Fn), and after a rotation of 90 ° or vertically for the shifting (beam Fr), a leveling receiver Rn and a shifting receiver Rr being both mounted on the machine, that is to say on a front measuring carriage (not shown) of the machine.
  • Figure 1 showing a side view of the leveling control device is illustrated by line 3 the old way which must be corrected, the faults of this way were naturally very exaggerated for the understanding of the figure, in dotted lines is illustrated the portion of this old channel which has just been corrected, line 4 represents the new corrected channel and the line in phantom 4 'represents the desired channel which is defined by the axis of the laser which is adjusted, at the start of work, parallel to this desired path.
  • the device comprises a laser transmitter 1, emitting a horizontal beam Fn and which is mounted on a carriage 5 stationary in a fixed position, at a location chosen on the old track 3, in front of the machine which is, in the present case, a tamper-grader-ripeuse symbolized by the chassis 2 and which will be hereinafter simply designated by machine.
  • This machine is equipped with a known relative measurement base, formed by the points A, B, C on the track, which are defined in a known way, for example by feelers belonging to measuring carriages rolling on the tracks. independent of the bogies of the machine, and suspended above the main chassis 2 of the latter. Point C defined by the rear measuring carriage is on track 4 already corrected.
  • Point A whose position in Figure 1 has been exaggerated, is on the track not yet corrected, this is why the chassis 2 is tilted forward.
  • the point B represents the working point which is therefore located near the working elements used to position the track and which are constituted, in the known manner, by shifting and leveling clamps. In Figure 1, point B has just been corrected, as point C is also corrected.
  • a laser receiver for leveling Rn which can be adjusted vertically with respect to the chassis of the carriage by means of an adjustment motor Mn.
  • a reference line Ln serves as a relative measurement base for leveling.
  • an element which carries the front end AL of this reference line Ln is fixed to the receiver Rn.
  • This end AL is located above point A.
  • this reference line Ln is assumed to be made by a taut wire on measuring trolleys. This wire is fixed at point CL situated at the height of point C and controls by its position in a well-known manner, via a control device, the position of the leveling clamps, at point BL, situated at the height of point B .
  • the laser receiver for leveling Rn like the laser receiver for shifting Rr which will be discussed below, consists of four photoelectric cells C1 to C4, shown in FIG. 3, and it is designed in such a way that it can be moved to the desired position by means of the adjustment motor Mn as a function of the line of impact of the horizontal laser beam Fn on the cells, the adjustment being carried out as soon as the beam is exactly between the two central cells C2 and C3.
  • this reference line Ln could be formed by any other mechanical means or not, for example a light ray, and the carriages of measurement defining points A and C are not necessarily below the chassis 2 but can be located on small auxiliary carriages which would roll at a fixed distance at the front, respectively at the rear of the chassis 2.
  • FIG. 2 a top view of the shift control device working with a vertical laser beam Fr has been shown in a manner similar to FIG. 1.
  • the shift receiver Rr installed like the receiver Rn, on the carriage front measurement is adjustable relative to this carriage on a transverse guide according to the vertical beam Fr by means of a motor M.
  • a reference line Lr serves as a relative measurement base for the shifting and is, in the example considered and for the shifts carried out on the rectilinear channels, linked to the receiver Rr.
  • the position of the reference line Lr already corrected is shown in FIG. 2 and in dashed lines the reference line L′r to the uncorrected state.
  • position A of the reference point includes the two points AG on the left rail and AD on the right rail.
  • the clamps for the track corrections to the horizontal and vertical planes at point B of the machine are actuated by positioning motors for leveling and shifting, controlled according to the deviations x B , respectively y B determined by the bases of relative measurements as shown in Figures 1 and 2.
  • the reference lines Ln and Lr forming the relative measurement base can also be arranged on the measurement carriages in a fixed manner and therefore independently of the receivers Rn and Rr, for example at the height of the central axis longitudinal of the front (point A) and rear (point C) measuring carriages or at the level of the guide rail.
  • the deviations x B respectively y B which determine the corrections of the channel are determined, from the deviations x A and y A , by the ratios x A / x B and y a / y B which only depend known distances AC and AB .
  • These deviations x A and Y A are given by the position of the receivers Rn and Rr on the basis of measurement relative to point A.
  • FIG 5 there is shown simultaneously, in perspective, the two systems and we see the horizontal beam Fn and vertical Fr and the two leveling receivers Rn which can move vertically and shifting Rr which can move horizontally.
  • the laser transmitter 1 is located on the axis of the track.
  • the rope was chosen as the measurement interval in which the machine moves step by step towards the transmitter without having to change the position of the latter, and the measurement initial was carried out at the intersection of the beam with the guide rail or track axis, in this way there were only the arrows of the rope located on the same side of the rail.
  • the maximum rope was of course limited by the condition that the maximum deflection did not exceed the possible travel of the receiver on the machine.
  • a larger measurement interval G ′ is chosen, which exceeds the chord beyond the point of intersection of the beam with the director rail or axis of the track, up to point A0 which represents, in the example chosen, the place of initial measurement and correction.
  • the maximum measurement interval G ′ must of course be chosen so that the sum of the maximum left and right arrows which are, in the example considered, the arrows fm0 + fm4, is compatible with the travel of the receiver Rr which s 'always adjusts to the beam Fr.
  • the machine follows the curve of track 3 and arrives successively after a distance traveled S1, S2, S3, S4 etc, at points A1, A2, A3, A4 etc, while the shift receiver Rr follows the beam vertical Fr of the laser and therefore always moves automatically on its carriage to the point of impact with the beam Fr. This position of the receiver each time determines the current value of the arrow fm1, fm2, etc.
  • the setpoint value of the arrow f1, f2, etc. which corresponds to the theoretical curve 4 ′ is calculated.
  • the calculator UC calculates the setpoint value of the deflection in a known manner for the curves and all the connection curves, as a function of the geometric data, such as the radius R of the curve, the length G ′ of the interval of chosen measurement, data for the variable radius of a connection curve which includes the length L of this curve, etc., and of the path traveled S, and compares it with the arrow measured, therefore the current value of this arrow. From the difference of the two values, the corresponding deviations y1, y2 etc. are calculated.
  • the setpoint value of the arrow f2 is zero, because the receiver is precisely at the point of intersection between the theoretical curve 4 ′ and the beam Fr.
  • the current value of the arrow fm2 is equal to the deviation y2.
  • the arrow f B of the relative measurement base must also be taken into account, as illustrated diagrammatically in FIG. 7 for a working position of the machine.
  • the arrow f B is the distance between the theoretical curve and the reference line forming a chord of this curve.
  • the theoretical curve 4 ⁇ is indicated relative to the relative measurement base with the reference line L ⁇ r not yet corrected; the arrow f B shown therefore relates to this theoretical curve.
  • FIG. 7 and of FIG. 8 shows the block diagram of control and command in a curve.
  • the variable data are introduced: the path traveled S, measured by a unit of measurement UM; the current value of the deflection fm measured by the receiver Rr as well as the tilt angle ⁇ measured in a known manner by a pendulum Pe.
  • the channels to be adjusted are always subject to superelevation faults and, therefore, it is essential to correct the deviation y A , respectively y B , as a function of the superelevation at the measurement points. This is done using a Pe pendulum, installed on the relative measurement base.
  • a reference line Lr adjustable independently of the position of the receiver Rr transversely by a motor Mf (FIGS. 8 and 9).
  • the difference y A appears at point A corresponding to the difference fm - f0, corrected if necessary by a correction depending on the angle ⁇ .
  • This difference y A controls the motor Mf which moves the reference line Lr to point A of this difference y A.
  • This corresponds to a gap y B at the working point B, where a stop, or a reference element, is moved with the reference line Lr defining the desired position or set position of the clamps which correct the rails.
  • the computer UR calculates the deflection f B of the relative measurement base from data S and R, respectively L and from the other data for the variable radius of a connection curve.
  • the calculator UR emits an output signal corresponding to this arrow f B which controls a second motor Mb (FIG. 8). This motor corrects the position of the mentioned stop relative to the reference line Lr by a distance equal to f B , such that the stop is now exactly on the theoretical curve 4 ′.
  • the clamps which engage the rails are moved from the shift correction ⁇ B by a hydraulic drive engaged until the track is at the set position defined by the stop, therefore on the theoretical line 4 ′.
  • the value ⁇ B is equal to the addition of the deviations y B and yf B , yf B representing the distance between the current position of the uncorrected channel 3 and the uncorrected reference line L′r.
  • the output signal y B of the computer UC can be introduced into the computer UR which directly calculates the total displacement y B + f B and gives a signal corresponding to the motor Mb.
  • the calculator UC it is also possible for the calculator UC to send a signal corresponding to the difference y A to the calculator UR which transforms it into a signal corresponding to the difference y B at point B. In this case, the calculator UC must not emit a signal y B.
  • the calculator UR gives a signal corresponding to f B to the calculator UC which emits a signal corresponding to the sum y B + f B as a control signal to the motor Mb.
  • the hydraulic drive of the grippers is therefore indirectly controlled by the UC and UR computers.
  • a position detector is provided which at all times determines the current position of the clamps and therefore of channel 3 and sends a signal relating thereto for the computer UR.
  • This UR computer calculates not only the arrow f B , but also from this arrow f B and from the signal which represents the current position of channel 3, directly the difference yf B ( Figure 7).
  • the clamps are controlled directly by means of the output signal y B of the calculator UC and the output signal yf B of the calculator UR, or else from the signal corresponding to the sum y B + yf B of the UR computer without the need to use a stop or a movable reference element which determines the set position.
  • the block diagrams corresponding to this way of controlling the hydraulic drive of the grippers would correspond to Figures 8, 8a and 8b with the only modifications that the motor Mb shown would represent the hydraulic drive of the grippers and that the output signal corresponding to the arrow f B should be replaced by the signal corresponding to the deviation yf B.
  • the unit EC shown in FIG. 8, 8a and 8b, which receives the signal y A , will be explained during the description of FIG. 10.
  • FIG. 9 shows a sectional view of the track and the front measuring carriage - seen from the front - at point A availability (FIG. 6) and, in phantom, at level of point A3, and this before correction.
  • the shifting receiver Rr is moved to the front end of the relative measurement base on the support 6 of the measurement carriage , at a distance from the central axis La of the measuring device (therefore the central longitudinal axis of the measuring carriages) equal to the value of the current deflection fm0, for example by means of a screw, driven by the motor Mr The vertical beam Fr is centered at the receiver Rr.
  • the front point AL0 of the reference line is moved on the support 7 of the measuring carriage by the motor Mf of the difference y0, therefore of the difference fm0 - f0 at the center of the theoretical way 4′0.
  • the receiver Rr has moved on the support 6 by the value of the measured arrow fm3 smaller than the theoretical arrow f3, making it possible to calculate the difference y3.
  • the front end AL3 of the relative base is moved on the support 7 of the measuring carriage at the center of the theoretical path 4′3.
  • the path of the receiver Rr has been shown on its support 6 during the measurements at points A0 and A4.
  • the maximum width that the transverse support 6 can occupy is generally 3 meters.
  • the effective shift value is stored in the calculation unit UC until the carriage measure 9 arrives at the measurement point A ′.
  • These shifted values (and the leveling values) stored are in the example displayed on an EC display, indicated in FIGS. 8, 8a and 8b, such as a screen, a recorder or other means. This allows the machine operator to intervene 10 to 20 sleepers before the job is done to make any corrections. It is obvious that the leveling system will be designed in the same way.
  • FIG. 11 an arrangement as illustrated in FIG. 11 is proposed.
  • the receiver Rn for the horizontal beam is mounted on the underside of a transverse support 6 along which the receiver Rr for the vertical beam can move, for example on a screw driven by the motor Mr , to perform the shift measurement.
  • the assembly of this support 6 with the receiver Rr and the receiver Rn is mounted on its side on a vertical support 8 along which said assembly can move vertically, for example on screws, driven by the motor Mn, so that the receiver Rn can perform leveling measurement.
  • This makes it possible to use almost the entire distance to the transmitter, as illustrated in FIG. 11a, and therefore to increase the effective interval G ′.
  • the receiver Rr which can naturally also be fixed to the upper face of the support 6, always moves vertically with the receiver Rn and is only at a small constant vertical distance from it.
  • interval of measure G ′ can be chosen wider than hitherto also means that the distances between the fixed markers or stakes installed along the track and defining the theoretical route can be greater and therefore that the number of these markers is reduced.
