Definitions

  • a mobile ballast cleaning machine comprises an endless bucket chain and a pair of guide arms mounted laterally of the machine frame and guiding the bucket chain between a first position wherein the bucket chain is immersed in the ballast underneath the track ties and extends widthwise transversely of the track, and a ballast discharge position above the track.
  • the width of the bucket chain in the first position transversely of the track is adjustable.
  • the present invention relates to improvements in a mobile ballast cleaning machine comprising a frame movable on a track including rails mounted on ties supported by ballast.
  • ballast excavating conveyor or bucket chain is mounted on the frame.
  • Guide means carry the bucket conveyor, and the guide means includes a pair of guide arms mounted laterally of the frame and guiding the bucket conveyor between a first position wherein the bucket conveyor is immersed in the ballast underneath the track ties and extends widthwise transversely of the track, and a ballast discharge position above the track.
  • a ballast cleaning screen is arranged to receive ballast discharged at the discharge position whereto it is moved by the conveyor from the first position where it excavates the ballast.
  • such machines may also include track lifting and/or lining mechanisms.
  • the endless bucket chain is guided downwardly along one of the guide arms into the ballast laterally adjacent the track, moves in a course extending transversely of the track through the ballast to excavate the same, and is then guided upwardly along the other guide arm with the excavated ballast to discharge the same onto a ballast cleaning screen.
  • the screened, clean ballast is then usually returned directly to the track bed.
  • the guide arms are mounted for horizontal and vertical pivoting on the frame, horizontal pivoting of the arms selectively changing the angle enclosed between the arms whereby the width of the bucket conveyor or chain may be adjusted in the first position thereof.
  • This mounting makes it possible to adjust the guide arms asymmetrically so that the machine will operate at a switch point where a branch track branches off to one side of the track.
  • Such an arrangement will also adapt the excavating conveyor particularly closely to the ballast configuration.
  • the adjusting means includes a multi-part carrier for the bucket chain at the first position thereof.
  • the carrier extends transversely of the track between the guide arms and has two or more parts. Respective ones of the carrier parts are pivotally connected to a respective one of the guide arms at one end thereof and to each other whereby the distance between the guide arms may be adjusted by pivotal adjustment of the carrier parts at their linking points.
  • Such an arrangement is very simple in structure and additionally provides for effective ballast cleaning.
  • the carrier may, for instance, consist of two carrier parts of equal length and thus forming an equilateral triangle. Where larger widths are required, stability necessitates the use of more than two carrier parts, for instance three, which are linked together and to the guide arm ends, for instance in the shape of a trapezoid.
  • a symmetrical arrangement of the carrier parts is desirable to enable the machine to be used for branch tracks departing from the switch point towards the right or towards the left.
  • an adjustable spacing device for adjusting the distance between the carrier part ends linked to the guide arms.
  • this spacing device is a cable line or tackle which enables the distance to be continuously adjusted during the cleaning operation.
  • a tackle is a very simple device which is light in weight and makes it possible to exert considerable adjusting force with relatively little power input.
  • the pivotal connections between the guide arms and the bucket chain carrier parts may be of particularly simple structure when the portions of the guide arms to which the carrier part ends are linked extend substantially parallel to the plane of the track.
  • the width of the machine will be held to a minimum when the portions of the guide arms adjacent the first position of the bracket chain are inwardly directed towards the track rails.
  • the width of the transverse bucket chain course is usually extended asymmetrically, i.e., only in one direction in which a branch track runs from a switch point, which could cause the machine to tip over sideways if the bucket chain course is too lop-sided. This is avoided where particularly wide track beds are to be cleaned by running two machine frames on adjacent tracks.
  • one of the guide arms for the bucket chain is mounted on one of the frames and the other guide arm is mounted on the other frame.
  • One frame may constitute merely an auxiliary frame mounting the guide arm and the associated guide rollers for the bucket chain while the other frame s that of the ballast cleaning machine proper whereon all ballast cleaning mechanisms are mounted, except that one of the lateral guide arms is not in use and the bucket chain is, in-
  • ballast cleaning machines side by side, interconnecting their bucket chains and guiding them over the respective outer guide arms of the machines while keeping the inner guide arms of each machine out of use.
  • FIG. 1 is a schematic side view of one embodiment of a mobile ballast cleaning machine according to this invention
  • FIG. 2 is a schematic top view of the machine of FIG.
  • FIGS. 3 and 4 illustrate the principle of the bucket chain operation in two operating positions according to the invention.
  • FIGS. 5 and 6 illustrate schematically embodiments of the bucket chain guides for cleaning wide ballast beds.
  • the mobile ballast cleaning machine is shown to comprise machine frame 12 movable on a track including rails 7 mounted on ties 3 supported by ballast 1.
  • An endless bucket conveyor or chain 2 is mounted on the frame for excavating the ballast underneath the track ties in a first position of the bucket chain wherein it is is immersed in the ballast and extends widthwise transversely of the track.
  • the bucket chain is guided by a pair of guide arms 4, 4 laterally of the frame between this first position and a ballast discharge position 5 above the track.
  • a ballast cleaning screen 6 is arranged on the frame to receive excavated ballast discharge at the discharge position 5.
  • Suitable guide rollers on the guide arms guide the endless bucket chain which is carried by the guide arms and trained about the guide rollers.
  • the illustrated machine is self-propelled flat-bed car carrying its own power plant 13 to move the machine along the track slowly while the endless excavator conveyor moves about its guide rollers to excavate ballast continuously as the machine advances.
  • a series of conveyors not further described and forming no part of the present invention, transports the cleaned ballast from the screen to a storage'car or directly back to the ballast bed.
  • a carrier for the bucket chain extends transversely of the track between the guide arms 4, 4 at the first position or transverse course of the chain.
  • This carrier has two parts 8, 8.
  • Each carrier part 8 has one end pivotally connected at 9 to a respective guide arm 4 at one end thereof for pivoting relatively to each other about a vertical axis.
  • the other ends of the carrier parts 8 are also pivotally connected at 10 for pivoting relatively to each other about a vertical axis.
  • the distance between the one carrier part ends may be adjusted transversely of the track, the carrier forming an equilateral triangle whose apex angle is variable. The size of this angle determines the extent of the spread between the guide arms 4, 4, i.e., the width of the bucket chain in the first position transversely of the track or the length of this bucket chain course.
  • the carrier parts 8, 8 are of equal length, i.e., the carrier is symmetrically arranged so that the machine may be operated equally towards a branch track on the right or on the left. However, it may also be useful, under special operating conditions, to arrange the intermediate link 10 off-center.
  • a spacing device is arranged between the joints 9, 9 on the ends of the guide arms, the preferred spacing device being a cable line or tackle.
  • the spacing device may be constituted, of course, by any suitable linear motor, for instance a hydraulic motor whose piston is linked to one guide arm and whose cylinder is linked to the other guide arm. Controlled supply of hydraulic fluid to the motor will thus adjust the spacing between the arms.
  • a tackle has the advantage that its adjustability is substantially infinite.
  • FIG. 3 illustrates the machine in operation on a straight track section when the width of the transverse bucket chain course is relatively narrow to permit traffic on an adjacent track to pass unhindered and/or to permit the machine to pass through tunnels while still making it possible to clean the entire ballast bed under the track.
  • FIG. 4 shows the outer limit of the spread to one side of the machine, this limit being reached when the two carrier parts 8, 8 come to lie almost in a straight line and while the machine is still stable. In the illustrated position, the machine can clean a bed having a width of about 6 meters.
  • FIG. 5 shows how machine cleaning of the ballast may be effected according to the invention under such conditions.
  • an auxiliary frame 18 moves on a track adjacent to the track on which frame 12 moves.
  • the auxiliary frame carries an auxiliary guide arm 4'.
  • the bucket chain 2 is guided over one guide arm 4 on the main frame 12 and the auxiliary guide arm 4 on the auxiliary frame 18, a bucket chain carrier being linked to the lower ends of the guide arms to span the entire width of the bed to be cleaned.
  • a common bucket chain orconveyor 2' is trained over the guide rolls on the pair of guide arms mounted on the two adjacent frames and the multi-part carrier 8' has three carrier parts linked together in the form of a trapezoid, the one ends of the outer carrier parts being pivotally connected to the guide means at joints 9, 9' while their other ends are linked to an intermediate carrier part.
  • Tackles 20 and 21 interconnect the diagonally opposite carrier links while tackle 19 interconnects links 9', 9 on the guide arms.
  • This spacing device determines the spread of the arms and, thus, the width of the transverse bucket chain course immersed in the ballast which may reach about eight meters with this arrangement.
  • This device 22 may consist simply of spring loaded pivoting arms mounted on the respective frames and bearing against the endless bucket chain.
  • FIGS. 5 and 6 may be modified by using two like ballast cleaning machines wherein the inner guide arms are not used (as shown in light lines in FIG. 5), the two outer guide arms of each machine being used to guide a common bucket chain.
  • the machine has been advanced into the switch point from the narrow portion thereof so that the bed progressively widens as the machine advances, necessitating a spreading of the guide arms and a corresponding relaxation of the tackle controlling the spacing between the guide arms.
  • the two guide arms are first spread apart and the tackle is operated to pull the arms towards each other as the operation proceeds towards the narrow portion of the switch point.
  • track lifting and/or lining mechanisms may be mounted on the machine frame, if desired, the illustrated embodiments being generally no more than exemplary of the scope of the present invention as defined in the appended claims.
  • a mobile ballast cleaning machine comprising 1. a frame movable on a track including rails mounted on ties supported by ballast,
  • guide means carrying the bucket chain including a. a pair of guide arms mounted laterally of the frame and guiding the bucket chain between a first position wherein the bucket chain is immersed in the ballast underneath the track ties and extends widthwise transversely of the track, and a ballast discharge position above the track,
  • ballast cleaning screen arranged to receive ballast discharge at the discharge position.
  • the mobile ballast cleaning machine of claim 1 further comprising means for mounting the guide arms for horizontal and vertical pivoting on the frame, horizontal pivoting of the arms selectively changing the angle enclosed between the arms whereby the width of the bucket chain may be adjusted in the first position thereof.
  • the adjusting means includes a carrier for the bucket chain at the first position thereof, the carrier extending transversely of the track between the guide arms, the carrier having two parts, each carrier part being pivotally connected to a respective one of the guide arms at one end thereof and the other ends of the carrier parts being pivotally connected whereby the distance between the one carrier part ends may be adjusted transversely of the track.
  • the mobile ballast cleaning machine of claim 3 further comprising an adjustable spacing device for adjusting the distance between the one carrier part ends.
  • the mobile ballast cleaning machine of claim 1 comprising two of said frames movable on adjacent ones of the tracks, one of the guide arms of the pair being mounted on one of the frames and the other guide arm of the pair being mounted on the other frame.
  • the adjusting means includes a multi-part carrier for the bucket chain at the first position thereof, the carrier extending transversely of the tracks between the guide arms, the carrier parts being linked to each other and to a respective one of the guide arms in four pivotal joints, and adjustable spacing devices extending diagonally between respective pairs of the pivotal joints as well as between one of the pairs of pivotal joints linking respective ones of the carrier parts to the guide arms.
