Definitions

  • the present invention relates to improvements in the correction of the position of a track, and more particularly to a novel control for correction. It is particularly useful in such track laying machines or trains replacing the track in an old track section by an entirely new track.
  • a reference system which includes a reference line or plane associated with one of the track rails and which extends in a direction opposite to the working direction of the mobile track working machine towards the track correction station between two end points spaced from each other along the track one in the old track section and the other in the newly laid uncorrected track section.
  • the position of the reference line or plane solely depends on the position of the track in the old track section.
  • any changes in the track level or alignment due to such track working operations as track laying may be corrected immediately during the operation itself so that the track assumes at least an approximately correct position which is good enough, at any rate, to make it possible for trains to pass thereover and which may be, if desired, further corrected to a desired degree of accuracy in a subsequent fine correction operation.
  • the reference plane is fixed at one of the track points in respect of a reference plane perpendicular or parallel to the plane of the track.
  • the necessary parameters required toproduce the desired track position may be more readily determined in respect of such a fixed plane than in relation to a reference line.
  • the position of the reference may be determined solely by the position of its forward end, seen in the working direction. This may be effected by a frame guided along the associated track rail in the old track section on two running gears spaced from each other along the track. The position of such a frame corresponds to that of the old track and the reference determined by this frame position will thus depend solely on the track position in the old track section. lf the frame is of sufficient elongation, any minor unevenness in the old track section will be evened out.
  • an intermediate station is arranged in the old track section in contact with the reference system, and a control for the reference positioning means is operable in dependence on the position of the intermediate station.
  • the intermediate station may be temporary or permanent.
  • the reference line or plane may be positioned by adjusti'ng the forward end of the reference and/or the intermediate station, for instance by pivoting or otherwise moving the forward end of the reference and/or the intermediate station vertically and/or laterally. Such an arrangement makes the reference system readily and rapidly adjustable.
  • suitable and conventional means for determining and/or controlling such superelevation may be mounted either at the forward end of the reference, at an intermediate station or at the track correction station.
  • the reference may be constituted by a beam of electromagnetic radiation, for instance infra-red of light or and in such case, a beam masking means may be positioned at an intermediate station.
  • the beam masking means is supported on the associated track rail and the distance thereof from the rail corresponds to the distance of the reference end from the track.
  • the preferred reference is a laser beam beam defining a reference line or a reference plane. In this case, it is sufficient to mount the laser beam emitter adjustably in dependence on the position of the associated track rail in the old track section, thereby to determine the position of the reference as the laser beam is projected towards the track correction station.
  • tensioned wires and like elongated mechanical elements may also be used as a reference, in which case a mechanical contact element is mounted at an intermediate'station in the old track section to determine the position of the tensioned wire when the same is in contact with the mechanical contact element, such as forked support.
  • the track working machine includes track working tools at the track correction station, and means at the end of the reference closer to the previously corrected track section for determining the difference between the actual and the desired position of the track at the track correction station to survey the track position at the point where it has been changed by the working tools and requires correction.
  • FIG. 1 is a schematic top view of a track laying or renewal machine including two trains for respectively taking up and laying track;
  • FIG. 2 is a schematic side view of a modified track laying and renewal machine
  • FIG. 3 is a schematic side view of yet another modification of such a machine
  • the track working machine partially shown therein is an apparatus for replacing an old track by a new track, such as disclosed and claimed, for instance, in our U. S. Pat. No. 3,330,219 and No. 3,521,565.
  • a machine comprises a forward train, seen in the working direction indicated by the horizontal arrow, and represented only by its last car 1 designed to receive the old ties and from which the new track rails 2 are continuously deposited at the track correction position as the train advances in the indicated working direction.
  • the car 1 carries a means for positioning the reference line 3.
  • this reference could be a rigid rod fixedly mounted on a carrier on the car so that the position of the car on the old track section alone determines the position of the rod in'its extension towards the track correction station, i.e. the point where the new track is laid.
  • the reference is a laser beam 3 which is emitted from an emitter 7 mounted for universal adjustment on car 1.
  • the car 1 is supported on the old track 6 by two running gears 4 and 5 which are spaced along the track in the direction of track elongation.
  • the emitter 7 may be adjusted so as to be parallel with the car and to project the laser beam in the direction of track elongation (or it may be fixedly mounted on the car in this position) so that the laser beam position depends solely on the position of the car on the old track and the laser beam is always parallel thereto.
  • the running gears have flanged wheels whose flanges are pressed against a selected grade rail, thus making the car an accurate reference base.
  • the illustrated means for pressing the car against the grade rail is a pressure fluid motor 8, 9 engaging the old track 6 and operating in a conventional manner.
  • the determination of the desired position of the newly laid track rails 2 is effected by means positioned at the rear end of the reference 3, which is constituted by a laser beam receiver 10 in the illustrated embodiment.
  • the receiver 10 has laterally extending sensors 11 arranged for guidance along the new rails 2, such sensors consisting, for instance, of flanged rollers.
  • a pressure fluid motor 11' is connected to the receiver for pressing the same into a selected lateral direction for engagement of a flanged roller 11 with the selected grade rail of the new track. In this manner, the entire laser beam reference system is accurately positioned in respect of the old and new tracks.
  • the laser beam receiver has photocells or like light or heat-sensitive elements which produce control signals upon impingement of the laser beam to operate the control 12' for the lateral movement of the conventional track lining mechanism 12 which includes rail engaging rollers laterally movable in a selected direction by hydraulic motor 12" to line the new track.
  • the track lining mechanism is mounted at the forward end of the first car 13 of the rear train of the machine, over which the new ties are transported to the track laying station and which continuously receives the old track rails 6 as they are lifted off the ballast during the continuous forward movement of the entire machine in the manner fully described and illustrated in the aboveidentified patent and patent applications.
  • the reference system illustrated in FIG. 1 operates as follows.
  • the laser beam reference 3 is at least approximately parallel to the elongation of the newly laid track 2.
  • the laser beam receiver 10 runs with its rollers 11, 1 1 on the new rails 2, 2 and tends to follow the laser beam.
  • the receiver has light and/or heat sensitive cells or elements mounted laterally on both sides of the center of the receiver. As soon as the laser beam fails to becentered on the receiver, a lateral deviation will be registered by the impingement of the beam on one of the light and/or heat sensitive cells to produce a control signal which is transmitted by circuit 10' to the control 12.
  • the control 12 correspondingly operates the hydraulic motor 12" to move the track lining mechanism 12 laterally into one or the other direction until the new track is lined in respect of the old track so that the laser beam is again centered on the receiver. In this manner, the newly laid track rail remains aligned with the old track.
  • the track renewal machine of FIG. 2 is the same as that of FIG. 1 and, to avoid redundancy in the description, like structures operating in a like manner have been designated with the same reference numerals.
  • the reference is constituted by a conical light or infra-red beam 16 and the position of the reference line 3' of this beam is again dependent solely on the position of the old track 6 in the uncorrected track section. This is accomplished in the following manner.
  • a rearmost car 1' is spaced along the old track behind car 1, the car 1' also being supported on the track by a pair of spaced running gears 4, 5.
  • a light beam emitter 7' is fixedly mounted on car 1 and a masking means 17, such as a spotboard, is fixedly mounted on car 1' in the path of the beam 16 to determine the direction or position of the reference line 3' which is parallel to the old track.
  • the lower portion of the beam is masked by the spotboard 17 so that only reference line 3' is received by receiver 10', the position of this reference line being dependent solely on the position of the old track. As shown, it ispreferred to center the beam emitter and the beam mask between the running gears of the respective cars 1 and 1.
  • the illustrated machine includes conventional transport mechanisms for removing old ties l4 and laying new ties 15 on the ballast.
  • a ballast leveling machine 18 which determines the level of the new track consisting of new ties 15 and new rails 2.
  • the ballast leveling machine constitutes, in fact, a track position correction tool for the new track.
  • the ballast leveling means consists of an endless ballast moving conveyor 19 extending transversely across the right of way in contact with the ballast to level the same.
  • a hydraulic motor 18' is arranged to move the conveyor 19 vertically to a desired level of the ballast.
  • the hydraulic motor is operated by control 19" in re sponse to a control signal produced by receiver 10' when the reference line 3' impinges on light and/or heat sensitive elements mounted vertically on both sides of the center of the receiver in a conventional manner. In this manner, the reference line 3', whose position depends solely on the position of the old truck, controls the level of the new track. If lateral alignment is also desired, lateral alignment means controlled in the manner of FIG. 1 or 3 may be used with the modification of FIG. 2.
  • a reference line for controlling track alignment is constituted by a tensioned wire 3".
  • One end of the tensioned wire is anchored to a bracket extending laterally from car 1 and another end of the wire is anchored to a bracket extending laterally from a carriage running with flanged rollers 11 on new track 2.
  • An intermediate station which, in conjunction with the forward end 20' of the wire determines its position, is constituted by a forked holder 17 mounted on a laterally extending bracket on car 1 in the path of the wire.
  • This forked holder determines the vertical and lateral position of the'ten'sioned wire 3".
  • the desired position of the reference wire is attained when the wire passes contactfree between the contacts of the holder 17.
  • an electrical control signal is transmitted via relay 17" through electrical circuit 10" to control 12' which, in the same manner as in the embodiment of FIG. 1, operates the hydraulic jack 12" of the lining mechanism 12 to move the new track 2 in either lateral direction, dependent on the control signal from contact fork 17 until the control signal disappears as the wire looses contact with the fork.
  • the tensioned reference wire 3" may be used not only for lining the new track but also to level the same in respect of the level of the old track, with the aid of the ballast level lining machine 18, as described in connection with the embodiment of FIG. 2.
  • the vertically movable ballast leveling conveyor 19 carries a laterally extending bracket 21, which moves up and down with the conveyor.
  • the bracket 21 carries at its outer end a wire sensor in the path of tensioned wire 3" and cooperating therewith, this sensor including a rotary potentiometer 23 and a pivotal contact fork 24 operating the potentiometer upon pivoting of the fork by the wire, the pivoting direction of the contact fork or holder 24 being indicated by a double-headed arrow.
  • this sensor including a rotary potentiometer 23 and a pivotal contact fork 24 operating the potentiometer upon pivoting of the fork by the wire, the pivoting direction of the contact fork or holder 24 being indicated by a double-headed arrow.
  • the bracket 21 carries a conventional pendulum device 22 which indicates the superelevation of the track at this point.
  • the rotary poteniometer operated by the wire holder will transmit a control signal through electrical circuit 25 to operate the hydraulic motor 18 and correspondingly adjust the vertical position of ballast leveling conveyor 19.
  • the vertical position of the ballast leveler and thus the level of the new track will always depend on the vertical position of the reference wire 3" which is determined solely by the level of the old track.
  • FIG. 4 also shows the guide rails for old rails 6 and new rails 2 which are mounted on brackets 26 laterally extending from the ballast leveling machine 18.
  • FIG. 5 illustrates a useful laser beam emitter producing a planar laser beam 3, the emitter being movable in all directions, as indicated by the double-headed arrows.
