Definitions

  • ABSTRACT In track leveling and/or lining with a continuously advancing track tamper, the tarnping tools are continuously moved relative to the continuously advancing machine frame in synchronization with the machine advance in such a manner that the tamping tools are held in respective cribs while they tamp the ballast.
  • the present invention relates to improvements in a method and a mobile track tamping machine for correcting the position of a track in relation to a reference system.
  • the tamping machine comprises a frame, a track moving unit for raising and/or laterally shifting the track, which unit is mounted on the machine frame, and a plurality of ballast tamping tools mounted on the frame for tamping the ballast in the crib between the track ties.
  • the track position can be corrected very precisely and the quality of the tamping may be kept at the highest level to assure long lasting fixation of the track in the corrected position.
  • the tamping time need not be shortened to save time but it may be controlled so as to obtain the necessary tamping under all track conditions without the need for stopping the operation.
  • the above and other objects and advantages of the invention are accomplished by continuouslyadvancing a mobile tamping machine of the above described type along the track in a working direction while maintaining the track moving unit in continuous gripping engagement with the track rails while the machine continuously advances and the track is thus raised and/or lined in relation to the reference system.
  • the track moving unit is continuously operated while it grippingly engages the track rails to maintain the position of the track in a selected relation to the reference system, and the track is fixed in the maintained position by tamping the ballast with the tamping tools.
  • This is accomplished according to the present invention by continuously moving the tamping tools relative to the continuously advancing machine frame to hold respective tamping tools in respective cribs during the tamping of the ballast in the cribs while the machine advances continuously.
  • track correction is combined with track tamping in the continuous method of this invention since track leveling is not effective without tamping, i.e., fixing the leveled track in the corrected position.
  • such a machine comprises a machine frame mounted on the track for continuous advancement therealong in a working direction.
  • a track moving unit designed to raise and, if desired, to line the track is arranged on the frame for continuous gripping engagement with the track rails while the machine continuously advances, and a reference system is associated with the track for correcting the position thereof in relation to the reference system.
  • a control element indicates the position of the track and cooperates with the reference system for operating the track moving unit to maintain the position of the track in a selected relation to the reference system determined by the cooperation of the control element with the reference system.
  • a plurality of vibratory tamping tools are spaced. from each other in the direction of track elongation according to the spacing of the cribs and mounted on the machine frame for relative movement in relation thereto in this direction.
  • Means is provided for continuously operating the track moving unit in response to the control element, and a controlled drive moves the vibratory ballast tamping tools relative to the machine frame.

  • FIG. I shows a mobile track leveling and tamping machine comprising a machine frame 1 of considerable length.
  • the elongated machine frame is supported at its respective ends by running gears 2, 2 for mobility on the track, a machine frame portion of considerable length being suspended over the track section to be leveled and tamped.
  • the running gears may be swivel trucks, if desired.
  • the track consists of rails 3 and ties 4 supported on ballast (not shown).
  • the machine moves forwardly continuously while work is done on the track by the tools supported thereon, the working direction being indicated by the overhead arrow pointing to the right in the drawing.
  • a track lifting unit 5 is mounted on the forward portion of the machine frame in association with each rail 3.
  • the illustrated unit is conventional and comprises cooperating pairs of rollers which engage each rail and thus clamp the rail therebetween while the machine moves and without interference with such movement.
  • a hydraulic motor comprising cylinder 6 and vertically movable piston 7 is connected to these units to move the same vertically, the hydraulic fluid supply to the motor being controlled by a grading reference system in a known manner to lift the track to the desired grade.
  • This reference system which may take any suitable form, is illustrated as a conventional system comprising an emitter 8 of radiation, such as a beam of infrared rays or a laser beam, and a receiver 9 of the emitted beam of radiation, this beam between the emitter and receiver forming a reference 10 over the track section to be leveled or graded.
  • the beam emitter 8 is mounted on a support rod 11 which is vertically movable in a vertical trackway in the front portion of machine frame 1 and rides on rail 3 on a roller, thus to indicate the rail level.

  • the front point 8 of the reference 10 reflects the level of track in an uncorrected track section in advance of the machine while the end point 9 of the reference reflects the level of the corrected track section.
  • a beam emitter 8' is mounted on a self-propelled front bogie 13 which has its own drive 12 and supports the emitter 8 on rod 11.
  • the speed of drive 12 is radio controlled so as to select the distance between the front bogie carrying beam emitter 8 and the machine, which makes the reference system more flexible and adaptable to various track conditions, as is known.
  • emitter 8' may be moved synchronously with the machine frame 1, i.e., at the same speed, so as to maintain a constant distance between the emitter and the machine frame, or the bogie 13 may be moved at a different speed to synchronize its movement with that of the track tamping means (whichmove in a manner to be described hereinafter in relation to the machine frame).
  • the fixed position of the reference system in relation to the track tamping means during tamping, i.e., while the track is fixed in its leveled position, is of advantage for the accuracy of the operation.
  • the radio control of the speed of drive 12 is illustrated by a radiowave emitter 14 mounted on the tamping tool carrier frame 18 for movement in unison therewith and the radiowave receiver 15 fixedly mounted on bogie 13, such radio control being conventional and requiring no further description since it forms no part of the invention, except in the claimed combination.
  • a track correction control element constituted by a stop or beam sensing member 17 is mounted on the frame adjacent the path of the reference beam 10.
  • This stop is also mounted on the frame for free vertical movement and also runs on a roller on the track rail to indicate or reflect the level of the rail at this point which is chosen close to the tamping means where the track is fixed in the leveled position.
  • the stop 17, which moves up with the rail on which it rests, will intersect the beam, thus producing a control signal emanating from beam receiver 9 which terminates the operation of motor 6, 7, i.e., the lifting of the track, and may also be used, if desired, to terminate the operation of the tamping means adjacent the stop 17.

  • the opposing tools of each pair are arranged for immersion in the ballast adjacent one of the ties when the tamping tool carrier is lowered, with the one tie positioned between the opposing tools, and for reciprocation in the direction of track elongation.
