Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • the transmitter formed by a laser transmitter, is installed on a carriage which rolls on the track and which, during the measurement operation in an interval, is parked on the track in front of the machine near a fixed reference point .
  • the laser beam is divided into a vertical plane serving as a reference base for shifting, and a horizontal plane serving as a reference base for leveling.
  • the receivers automatically adjust to the vertical and respectively horizontal beam.
  • a machine in the form of a tamper-grader-ripeuse by means of which this method can be implemented is known from EP-B-0090098 and EP-A-0207197, both being deposited by the plaintiff.
  • the transmitter which is also parked on the track is preferably made up of a laser transmitter designed so that its beam can be rotated on its axis to emit a fan or scanning beam in a vertical plane and a horizontal beam.
  • This machine advances step by step, from cross to cross, and at each stop or cross we proceed to leveling then, after having turned the laser transmitter by 90 °, to shifting.
  • the machine can also work continuously with stuffing tools.
  • the rope of a section of track which is, in the known machine, formed by a laser beam in a fan or with scanning in a vertical plane, is used as absolute reference line.
  • This cord usually extends between the transmitter which is on the director rail or the axis of the track and the point of intersection of the beam with the director rail or the axis of the track.
  • the position of the reference line is called absolute because the successive positions of the transmitter are determined with respect to points fixed points which were defined during the first track layout and the correct position of the track is determined according to these fixed points.
  • These fixed points are materialized either by topographical markers, or by points located on pylons arranged next to the track.
  • a calculation system makes it possible to give the ray or laser beam the correct direction thus determining the base of absolute reference with respect to which the machine will be guided for leveling and shifting the track.
  • the deflection of the cord materialized by rays or laser beam is measured, it is compared with the known deflection of the desired curve, and the difference is calculated to obtain the value of lateral displacement of the way one way or the other.
  • the rope was chosen as the measurement interval in which the machine moves step by step or continuously towards the transmitter without having to change the position of the latter.
  • the initial measurement was carried out at the intersection of the beam with the director rail or with the axis of the track, 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 lateral travel of the receiver on the machine.
  • the carriage with the laser transmitter In practice, if you are on a section of track that does not have too much curvature, you can position the carriage with the laser transmitter at the start at a distance of approximately 350 to 400 m. of the machine, therefore larger than before, and once it has advanced during work too close to the transmitter, the carriage is again moved at a distance of about 350 to 100 m. of the machine.
  • the laser transmitter With this measurement system, the laser transmitter is placed in the center line of the track or on the director rail and the receiver on a mobile base at the head of the machine. After each length of measurement and work, the transmitter must be advanced to a distance which varies according to the geometry of the track, positioned in the axis of the track or on the directing rail using a measuring device.
  • a device for measuring a railway track comprising a laser transmitter placed next to the track and outside the gauge of free space of cars.
  • This transmitter is installed on a pivot axis, eccentrically with respect to this axis and above it, in such a way that above this pivot axis is a large open space in the area of the point d intersection of the laser beam with this pivot axis, to allow the approach of a deflection measuring device mounted on a riper machine.
  • the purpose of this arrangement is to create a straight line of reference between two fixed points such that said line can be followed by said deflection measuring device without interruption.
  • the object of the present invention is to remedy the drawbacks mentioned relating to known methods, and proposes a method for the repair of a railway track making it possible to reduce the stops of the machine and making it possible during the installation of the transmitter. the use of the section between the transmitter and the machine.
  • the method for repairing a railway track according to the invention is characterized by the characterizing clause of claim 1.
  • the advantages of the process according to the invention are linked directly to having the transmitter no longer on the axis or the guide rail of the track but next to it.
  • having the transmitter next to the track allows, on the one hand to also be able to use the section of the track between the transmitter and the machine, during the installation and adjustment of the transmitter and the start of the work of the machine on the section for intermediate work or the movement of materials, and on the other hand makes it possible to lengthen the length of the measurement and work interval, especially in curves as claimed elsewhere in claim 2.
  • being able to place the transmitter next to the track makes it possible to extend the working interval beyond the rope normally used, since the transmitter can be placed outside of the rope on the secant extending it, and therefore outside the curve.
  • the length of the measuring and working interval is lengthened and the machine stops for moving the transmitter are reduced.
  • the coordinates of the transmitter are measured relative to the fixed point and these values are entered in the calculation system to obtain the values of different points on the track according to the actual position of the transmitter.
  • the transmitter system is positioned maximum distance next to the track which is determined, on the one hand by the available free space, i.e. not encroaching on the possible parallel track and the space which is not intersected by pylons, fences, etc. which could exist alongside the track, and on the other hand with the lateral travel of the sensor system, which is linked to the maximum lateral travel of the shifting machine.
  • the second system of transmitters there are two systems of transmitters so that while the work is being carried out with the first system of transmitters, the second system of transmitters is placed on the track, defining the second interval of work so that when the machine comes close to the first transmitter system the machine is stopped to adjust the second transmitter system with respect to the receiver system.
  • the transmitter system used until then is loaded on a carriage which brings it to the next position, without hampering the adjustment work with the next transmitter system, since this second transmitter system is found outside the track and its beam is not interrupted by the carriage when it moves on the section which is between this second system of transmitters and the machine.
  • the machine While moving and carrying out the positioning and adjustment of the first transmitter in its new place, the machine, after having carried out the adjustment of the transmitter system in relation to the receiver system and entered the coordinates of the transmitter system in the calculator, can start repair work.
  • the work is stopped just until the final adjustment of the first system of transmitters in its new place relative to the system of receivers while we bring with the carriage the second system of transmitters to its new place and so on.
  • the transport of the transmitter systems is done on a self-propelled trolley with remote control which stops automatically at the point where the transmitter system must be positioned.
  • the invention also relates to a device for fixing the transmitter system next to the track as defined by claims 7 to 8.
  • the current position of the track is measured in relation to an absolute reference base, it is compared by means of a calculation system, to the theoretical coordinates recorded during the laying of the track, and the machine is ordered to correct the position of the track both in height (leveling) and laterally (shifting).
  • the transmitter always next to the track allows, as mentioned previously both during work as well as the positioning and adjustment of the transmitter to a new position, to use the section of the track For transport.
  • Another advantage is that when the repair work is done in a curve of the track the fact of placing the transmitter next to the track lengthens the length of the work interval.
  • the machine 1 advances on track V until the receiver Rr arrives at point A, which is the point closest to the transmitter E1, located at point B, allowing measurements to be made.
  • the first working interval P1 is thus traversed.
  • the second transmitter E2 While the machine 1 is working on the interval P1, the second transmitter E2 is positioned at a point B1, and its coordinates are measured relative to the corresponding fixed point to define the absolute reference base for the second measurement and working interval P2.
  • machine 1 comes to the end of the interval P1, either at point A, it is stopped and the transmitter E1 is loaded on a self-propelled carriage 2 to be driven to a position B2.
  • the final adjustment of the transmitter E2 is made with respect to the receiver Rr and the repair work begins in the second measurement and work interval P2 defined by the points A and A1 even if the carriage 2 is still on the section of the channel V corresponding to this second interval.
  • the time for stopping the machine is reduced only to the final adjustment of the transmitter relative to the receiver, the movement, the positioning and the measurements of its coordinates having been carried out while the machine 1 was working on interval P1.
  • each working and measuring interval P1, P2, P3, etc. depends on the configuration of the terrain and the track so that the rays emitted by the E1 or E2 transmitter are not interrupted by pylons, fences, etc., and in particular, on the curves they are based on the maximum displacement possible from the shift receiver.
  • the two intervals P2, P3 are of different length because as shown in Figure 3, P3 is on a curve.
  • the transmitter is placed on the left or right of the track but in any case in the curves the transmitter is always placed outside the arc (fig. 3)
  • FIG 4 there is shown schematically, the device supporting a transmitter E next to the channel and the different setpoint coordinates and relating to a fixed point F for the determination of the absolute reference base.
  • the device supporting the transmitter E Beforehand, we will describe the device supporting the transmitter E.
  • a base 7 placed on crosspieces 3 and provided at one end with a clamp 8, making it possible to attach it to a file of adjacent rails 5.
  • an axis 9 is arranged to which is articulated a support 10 provided with a column 11.
  • the articulation 9 can be moved in the horizontal plane by means of a screw not shown, making it possible to move the distance meter D as well as the emitter E with respect to the theoretical axis of the channel.
  • the support 10 carrying the distance meter D and the transmitter E which are on the same axis, can be placed vertically using the screw 12.
  • a sliding piece 13 secured to a nut 14 collaborating with a screw 15 parallel to the column 11.
  • the lower end of the screw 15 rests against a thrust bearing 16 secured to the column 11.
  • a piece 17 mounted at right angles to the sliding piece 13 serves to support the transmitter E.
  • the screw 15 is used to adjust the height of the transmitter E.
  • a distance meter D is fixed to the transmitter E. It is obvious that two such supports are used for each of the transmitters E1, E2.
  • the determination of the absolute reference base is carried out as follows (fig. 4).
  • the transmitter E is placed with its support device facing a fixed point F which in the present case is materialized on a pylon 19 next to the platform of the track.
  • a fixed point F which in the present case is materialized on a pylon 19 next to the platform of the track.
  • the value N L must be corrected according to the slope.
  • the theoretical axis 6 rarely coincides with the axis of the track.
  • the values R L and N L are entered into the calculation system which indicates the direction of the beam of the transmitter and will subsequently indicate the corrections to be made taking into account the position of the transmitter E.
  • This carriage 2 includes a bracket 20 with a lifting system 21 provided with a hook 22.
  • This carriage 2 is preferably self-propelled with remote control, automatically stopping at the desired location.
