  • Machines of this general type have become well known and widely used, and more recently, we have developed such machines with a plurality of tamping tool assemblies spaced along the direction of track elongation for simultaneously tamping a succession of similarly spaced ties in a single operational stage. While such machines greatly increase tamping efficiency, problems have arisen in avoiding excessive weight and commensurate pressure on the machine axles, as well as in the mounting of the heavy, vertically adjustable tamping tool carriers.
  • a track liner wherein means for laterally aligning the track is mounted on the machine intermediate its front and rear trucks.
  • a variety of track surfacing and maintenance tools are mounted on a bridge-like carriage frame whose two ends are supported on trucks for movement on the track, including a preferably vertically adjustable carrier for a plurality of tamping tool assemblies spaced along the track elongation for simultaneously and efficiently tamping a succession of similarly spaced ties.
  • two like machine frames are turned towards each other with their open front ends and are pivotally coupled together to form the bridge-like carriage frame on which the track maintenance tools are mounted centrally of the swivel trucks which support the machine on the track.
  • the two forwardly extending machine frame portions bridge over the track section on which work is done and this construction makes it possible to extend this section over many ties to be covered in a single operational stage, i.e. to level and/or line a comparatively long track section and simultaneously to tamp the leveled and/or lined ties in this one operation.
  • the tamping tool carrier is centrally mounted on a bridge-like carriage frame whose two ends are supported on the track on swivel trucks.
  • a frame may be sturdy enough for the tamping ice tool carrier to be suspended thereon, for instance by hydraulic motors which also serve to adjust the carrier vertically in relation to the track and which may be independently supported on trucks running on the track. In this manner, the track section between the frame ends remains free of interfering support element and may be taken up entirely by track maintenance tools.
  • the entire heavy weight of the tamping and lining machine, which rests on the trucks, is transmitted to the track below the machine so that the previously graded and tamped track is held down firmly and prevented from assuming a wrong grade again during lateral alignment.
  • this location of the track aligning means makes it possible most fully and efiiciently to use the entire length of the machine for the mounting of various operating devices so that the machine can be used for grading, aligning and tamping, such devices including a plurality of tamping tool assemblies, means for compacting ballast in the strips extending laterally of the track, and reference lines in relation to which the track is leveled and/or laterally aligned.

  • At least one tamping tool carrier 6 is vertically adjustably mounted on the bridge-like carriage frame, each carrier being vertically movable along posts 7 which support the carrier in the carriage frame, and each carrier holding a plurality of tamping tool assemblies 5.
  • Track lining and/or grading means is also mounted on the bridge-like carriage frame, the schematically illustrated track position correcting means including a hydraulic jack with a cylinder 8, a vertically movable piston 9 and a track gripping means 10 connected to the piston for movement thereby.
  • the track correcting means may be entirely conventional, as may be the track grading and/ or lining system including reference line 11, in relation to which the track is graded or leveled.

  • the track gripping means 10 includes two track clamping devices which are spaced from each other along the longitudinal extension of the track and which, in a known manner, include rollers glidingly engaging the rails so that the clamping devices may remain engaged with the track rails while the machine moves therealong.
  • each tamping tool carrier 6 holds two tamping tool assemblies for simultaneously tamping a total of four ties.
  • the distance between the tamping tool carriers is such that a pair of ties intermediate the pairs of ties being tamped remains untamped (see FIG. 5).
  • the machine is alternately advanced by a distance of six and two ties so that the two ties, which remain untamped in each tamping stage, are subsequently tamped.
  • the distance between the tamping tool carriers is increased so that four ties intermediate the pairs of ties being tamped remain untamped, two track lifting means being mounted in the space between the tamping tool carriers.

  • a pair of hydraulic motors 106' vertically adjustably mount the tamping tool carrier on the bridge-like carriage frame, each hydraulic motor being independently supported on the track by auxiliary trucks 106" which run on the track.
  • the carrier 106 has track gripping means 110 within the range of the auxiliary trucks to enable the track to be lifted with the carrier.
  • the frame 134 of a track liner is pivotally coupled to the rear truck 102 with a king pin or like pivot joint 134'.
  • the frame 134 carries not only track lining tools 135 but also surface tampers 136 and ballast cleaning devices 137 which may consist of rotary brooms.
  • Grading or leveling of the track is controlled by reference line 111 extending from a front bogie 112 carrying sender 113 to a receiver 113' positioned in the carriage frame 101 rearwardly of the tamping tool assemblies and supported directly on one of the track rails.
  • a grading control system is well known and includes a stop 121 carried by two spaced rods 122, 123 which rest directly on the track so that the stop moves upwardly together with the track when the later is raised.
  • the two stop support rods 122, 123 are arranged adjacent the respective ends of tamping tool carrier 106.

  • FIG. 9 illustrates clearly to what extent the tamping tool carrier 106 must be moved laterally in curved track sections to assure that the tamping tool assemblies are properly associated with the respective track rails.
  • This figure also shows the advantage of using swivel trucks for supporting the ends of bridge-like carriage frame 101 on the track.
  • Various means may be used to make the tamping tool carrier laterally adjustable in relation to the carriage frame.

Furthermore, the two independent hydraulic motors 106, 106 have the advantage that the track may be lifted to different levels at spaced points. Such an arrangement makes it possible to level a relatively long track section accurately, particularly when the control stop 121 is carried by two similarly spaced support rods 122, 123.
