Definitions

  • MOBILE TRACK MAINTENANCE APPARATUS [72] Inventors: Franz Plasser; Josef Theurer, both of .lohannesgasse 3, 1010 Vienna, Austria [22] Filed: Oct. 7, 1969 [21] Appl.No.: 864,384
  • ABSTRACT In a mobile track laying apparatus, the forward end of an overhanging portion of a support frame is supported on a full-track running gear extending in the direction of track elongation.
  • the support frame bridges the location where the new ties are laid and supports a plurality of mechanisms for transporting the new ties to this location.
  • the present invention relates to improvements in mobile track maintenance apparatus adapted to move in the direction of track elongation.
  • Conventional apparatus of this type comprises a support frame elongated in this direction and supporting a plurality of track maintenance mechanisms, such as conveyor means for transporting the ties to and from the working location and means for taking up and laying ties at such location.
  • the support frame has a portion overhanging what is normally a section of the track free of rails where the maintenance work is to be performed by these mechanisms, and a running gear supports the overhanging support frame portion, the other end of the support frame being supported on a carrier vehicle which preferably runs on the track rails and may consist of a transport and storage vehicle for the ties.
  • a full-track running gear will not only assure proper weight distribution and stability but, additionally, will aid in flattening and compacting the track-free ballast at the working location, which is advantageous in the subsequent laying of the new track.
  • the full-track running gear is mounted in the center of the right-of-way or track and a pair of auxiliary running gears are provided laterally adjacent the full-track running gear at each side thereof. While the auxiliary running gears have been described and illustrated as wheels, they could also be fulltracks and, if desired, a pair of full-track running gears could be mounted side-by-side symmetrically of the track center line.
  • FIG. 1 is a top view of the apparatus
  • FIG. 2 is a side view taken in the direction of arrow II of FIG. 1 and also showing the rear support;
  • FIG. 3 is a front or sectional view taken along line IlIlIl of FIG. 1.
  • elongated tie conveyor 1 The lower end of elongated tie conveyor 1 is seen adjacent tie turntable 8, pairs of ties 3 being received from the conveyor and deposited on a conveyor band 8' on turntable 8.
  • Sensors 26 at the end of conveyor 1 are activated by the ties moving thereover onto conveyor 8', the sensors being activated to stop movement of the conveyor 1 when a preceding pair of ties remains on conveyor 8' and thus prevents movement of the succeeding pair of ties ofl the conveyor 1. The sensors will thus remain depressed by the ties at the end of the conveyor, causing the endless band of the conveyor 1 to stop.
  • Another pair of sensors 27, 27 at the end of conveyors 8 controls turning of turntable 8.
  • turning of the turntable will be initiated automatically so that the ties on conveyor 8' will be moved through until one of the ties contacts sensor 28 which controls stoppage of the turntable movement while initiating movement of the endless conveyor bands 12, 12 mounted laterally adjacent the turntable to receive the turned ties.
  • the conveyors 12, 12 are lifted from a lowered position for moving the ties off the conveyors 8' and forwardly in the direction of the track (see arrows) to the point at which the ties are to be laid on the ballast.
  • the conveyor pair 12 is lowered again to the level of another, shorter pair of conveyors 13, 13 to deposit the ties on the latter conveyors while actuating another sensor 29 which is also part of the tie transport control system and may be used to initiate the return of the turntable to its original position wherein the turntable conveyor 8' are in alignment with the elongated tie conveyor 1.
  • another sensor 29 which is also part of the tie transport control system and may be used to initiate the return of the turntable to its original position wherein the turntable conveyor 8' are in alignment with the elongated tie conveyor 1.
  • the turntable 8 is not only rotatable but also pivotal for adjustment to the inclination of conveyor 1 so as to facilitate the movement of the ties from conveyor 1 to conveyor 8'.
  • the short conveyors 13 move the ties to a pair of roller conveyors 25, 25.
  • Sensors 30 are associated with the roller conveyors and are actuated by the ties as they move forwardly to control stoppage of the conveyors 13.
  • the roller conveyors being quite short, this control assures the placing of a single tie on the roller conveyors at any one time.
  • Stops 31 are provided at the end of the roller conveyors to position each tie correctly in relation to the track elongation, i.e. accurately perpendicular thereto.
  • a further control 32 with sensor 32' senses the position of the tie in the direction of its elongation. If the tie is in the correct position, control element 32 initiates the downward pivoting of roller conveyors 25 towards stop 33, as indicated by the arcuate arrow in FIG. 2.
  • the roller conveyors pivot downwardly, the tie remains supported on the arms of a fork 5 arranged between the pair of roller conveyors.
  • the support fork 5 is vertically adjustable and pivotal by pressure fluid operated cylinder 5" so that each tie may be softly deposited on the ballast, the movement of the support fork being initiated by the actuation of stop 33.
  • the entire tie transport and laying mechanism is mounted on support frame 7.
  • the rear end of this support frame is supported on the support carrier 38, such as a tie transport car with wheels 39 running on the newly laid track 40, as more fully illustrated in the above-mentioned patent application.
  • the forward end of the support frame 7, in relation to the working direction of the apparatus indicated by the horizontal arrow in FIG. 2, is supported on a full-track running gear 9 extending in the direction of track elongation.
  • the full-track running gear 9 is positioned in the center of the right-of-way.
  • the length of the full-track support 9 is chosen in relation to the weight to be supported and the flattening pressure exerted upon the ballast.
  • auxiliary running gears 9, 9' mounted on both sides of the full-track running gear 9.
  • the illustrated auxiliary running gears are pneumatic tires which are mounted on a bell-crank lever 35 which is pivotal about the forward axle of the full-crank running gear so that the auxiliary running gears may be brought to different heights according to the superelevation in track curves. If the wheels 9' are driven, it is advantageous to drive them independently so that they may move better in curves.
  • the auxiliary running gear may, of course, consist of pairs or triplets of wheels, or they may also be full-tracks.
  • the running gears are mounted in a frame 37 and the support frame 7 is mounted on frame 37 by means of pivot 36 which permits lateral movement of the frame 7 in relation to frame 37 so that the running gears may be steered.
  • the auxiliary running gears 9 are yieldingly coupled to the support frame 7 at 34.
  • the running gear support frame 37 can be laterally pivoted so as to steer the front of the apparatus by operation of the pressure fluid controlled cylinder 9" which is connected between the support frame 7 and the running gear frame 37 so as to pivot the frame 37 laterally about pivot 36.
  • the support frame 7 has laterally and upwardly extending arms in its bridge-like forward extension supported on the running gears 9, 9, which arms carry guide grooves 7 for track rails 2. As shown, two such guide grooves are provided on each side, one for holding the old rails taken off the bed and the other one containing the new rails to be laid.
  • a mobile track maintenance apparatus adapted to move in the direction of track elongation, comprising a support frame elongated in said direction and supporting a plurality of track maintenance mechanisms including tie conveying means elongated in said direction, said support frame having a forward portion extending in said direction and overhanging a trackless section where track maintenance work is to be performed by said mechanisms, a rear portion supported on a carrier running on the track, and a running gear supporting the overhanging portion of the support frame, the improvement of said running gear including a full-track running gear extending in said direction.
  • the full-track running gear being centered in relation to the track.
  • auxiliary running gears laterally adjacent the full-track running gear for distributing the weight of the support frame portion supported thereon and stabilizing the support of said portion at the outer end thereof.
  • each auxiliary running gear being vertically adjustable.
  • each auxiliary running gear being adjustable in the direction of track elongation.
  • said auxiliary running gears comprising wheels with pneumatic tires.
  • the overhanging portion of the support frame extending bridgelike to the running gear support, and said bridge-like support frame portion having two laterally and upwardly extending support arms defining guides for holding track rails.
  • a mobile track maintenance apparatus adapted to move in the direction of track elongation, comprising a support frame elongated in said direction and supporting a plurality of track maintenance mechanisms including tie conveying means elongated in said direction, said support frame having a forward portion extending in said direction and overhanging a trackless section where track maintenance work is to be performed by said mechanisms, a rear portion supported on a carrier running on the track, and a running gear supporting the overhanging portion of the support frame, the improvement of said running gear including a full-track running gear extending in said direction and being centered in relation to the track, vertically adjustable running gears laterally adjacent the full-track running gear for distributing the weight of the support frame portion supported thereon and stabilizing the support of said portion at the outer end thereof, and a bellcrank lever mounting the auxiliary running gears for vertical adjustment, the bell-crank lever being pivotal about an axle of the central running gear.
