Definitions

  • the present invention relates to the continuously progressing replacement of old track by new track by means of a train moving along a right of way consisting of a section of old track, a section of new track and a trackless intermediate section wherein the old track is replaced by the new track on the ballast bed in the intermediate section, and more particularly to the ballast treatment in this section before the ties of the new track are laid thereon.
  • Track replacement apparatus of this general type has been described, for instance, in our U. S. Pat. No. 3,330,219, dated July 11, 1967, and US. Pat. No. 3,521,565, dated July 21, 1970.
  • An improved apparatus of this type has been disclosed and claimed in our concurrently filed application entitled Movable Apparatus for Replacing an old Track by a new Track.
  • Such apparatus includes a first train section of cars moving on the old track rails and a second train section of cars moving on the new track rails.
  • Means on respective cars including vertically and/or laterally moving implements, transport and support the rails and/or the ties of the old and new track, respectively receive and lay the rails and/or the ties of the old and new tracks, and guide without friction the track rails bridging the intermediate trackless section of the right of way. All these implements are controlled and operated in timed sequence during the continuous movement of the train assembly.
  • various means are arranged for movement in the trackless intermediate section of the right of way independently of the movement of the train sections, which sections also move independently of each other.
  • the independently movable means include implements for receiving and/or laying track parts, and for working on the ballast.
  • Sequential portions of the ballast are continuously removed from the trackless ballast section during the continuous advancement, the removed ballast is cleaned, cleaned portions of the ballast are continuously returned to the trackless ballast section, and the cleaned ballast is substantially uniformly distributed and leveled, and preferably compacted, before the ties of the new track are placed thereon.
  • Sequential portions of the rails of the new track are lowered and moved together to assume the gage of the new track substantially without friction, and the lowered rails of the new track are fastened during the continuous advancement.
  • an intermediate train section bridges the trackless intermediate section of the right of way, this intermediate train section is linked respectively to the first and second train sections to interconnect the same for common movement, and the intermediate train section includes means for maintaining the respective linking means at a predetermined distance in the direction of the right of way. Associated therewith are means for removing ballast from the trackless intermediate section, cleaning the removed ballast, and redistributing the cleaned ballast.
  • At least a portion of the cleaned ballast is uniformly distributed in selected cribs of the new track during the continuous advancement and preferably after the rails of the new track have been fastened to the ties of the new track.
  • the contour of the uniformly distributed and leveled cleaned ballast in the trackless ballast section is controlled during the continuous advancement by sensing the height and preferably also the lateral alignment of the ballast bed after removal and redistribution of the ballast, respectively. In this manner, the trackless ballast section is graded and aligned while the continuous track replacement is effectuated.

  • a flat car 3 forms the rear. end of the forward train section and carries a schematically illustrated device, such as a trolley, for transporting the old ties 5 to the cars 1 and to place them on respective ones of these cars as the trolley runs over the flat platforms of these cars.
  • Car 3 also carries a schematically illustrated implement 6 for loosening the rail spikes of old rails 7 which are shown in full lines.
  • a universal pivot 11'' vertically above the running gear 8 of car 3 pivotally'supports a support arm 11 extending towards the intermediate section of the right of way.
  • a support arm 11 extending towards the intermediate section of the right of way.
  • Hydraulic drive means 19" is connected to bucket conveyor 19 of the ballast cleaning machine so that the conveyor may be moved into an operating position in engagement with the ballast even in the lifted position to elongated conveyor 24 which discharges it into chute 25 mounted on first car 26 of the rear train section, whence it is moved rearwardly by conveyor 35, so that the cleaned ballast may be deposited in a crib of the new track immediately behind the point where the rails of the new track have been fastened to the ties of the new track.
  • the frame 16 carries a vertically adjustable ballast leveling device 29 within sight of the operating stand 28 to level the cleaned ballast returned to the trackless intermediate ballast section.
  • a pair of laterally pivotal conveyor bands 30 are arranged to convey portions of the cleaned ballast from screen 21 forwardly, in the working direction of the apparatus, the input end of the conveyor bands 30 being placed below the chute 23.

  • the level as well as thealignment of the ballast bed for the new track is controlled by means of a reference system including a reference line 36.
  • the reference line may be formed by a beam of radiated energy, such as an infrared or laser beam.
  • a beam emitter 37 is mounted in the range of the old track so that the beam extends from the old track in a desired direction into the new track.
  • This beam constitutes a reference line for the positional adjustment of the ballast working implements, more particularly the ballast removal conveyor 19, whose vertical position determines the depth to which ballast is removed, and ballast leveling device 29, whose vertical position determines the grade of the cleaned ballast redistributed over the bed.
  • the reference line cooperates with sensing means constituted by stops 36 cooperating with the reference line to control the positional adjustment of conveyor 19 and leveling device 29 in a manner well known in track reference systems.
