  • a ballast machine would include any of these types of machines.
  • Railroad ballast consists of rocks or stones which lie between and under the railroad ties.
  • the ballast serves to stabilize the ties upon which the rails are mounted. Also, the ballast allows water to quickly drain away from the rails.
  • ballast gets filled with dust from the ballast and dirt blown in from nearby.
  • the ballast may harden into material similar to cement. It may also lose its ability to drain water. Under such circumstances, it is necessary to replace the ballast with completely new ballast or to remove the ballast, clean it, and put the cleaned ballast back in the roadbed.

  • undercutter mechanisms which either have problems operating in areas with obstructions (near switches, etc.) or the undercutter mechanisms can operate in areas with obstructions, but are less efficient in other areas. Having a type of undercutter for areas with obstructions and a different type of undercutter for other areas disadvantageously requires two machines for undercutting.

Instead, the undercutter would be above the cross tie (tie not shown in Fig. 13) . When the trench is dug, the lifter 14 would be lifted out of it and the undercutter 12F would be lowered therein to remove ballast from under and between the ties.

  • undercutter 12F is mounted to an undercutter carriage 62 which moves up and down relative to assembly 56 by the way sliding along posts or vertical bars 60S and 60T (see Fig. 16) under control of carriage lift cylinder 62C having its upper end fixed to assembly 56 and its rod end fixed to carriage 62.
  • Lifter 14F is mounted to a lifter carriage 64 which moves up and down relative to assembly 58 by way sliding along posts or vertical bars 60F and 60S (see Fig. 16) under control of carriage lift cylinder 64C having its upper end fixed to assembly 56 and its rod end fixed to carriage 64.
  • Lifter 14F is mounted to rotate about axle 14A under control of tilt cylinder 14T. This advantageously allows 14F to move between the near horizontal travel orientation of Fig. 14 and the more inclined working position of Fig. 6. In its near horizontal position, it may readily pass under overhead obstacles or obstructions that lifters made in a wheel shape might be too large to pass under.
  • Fig. 14 shows lifter 14F smaller relative to carriage 64 than it would be in practice. In actual construction, the lifter 14F would, in its working position (refer momentary to Fig. 5) extend up to or above the top of assembly 56. Therefore, its ability to use cylinder 14T to tilt to a more horizontal position will be advantageous in avoiding overhead obstacles. Indeed, the tilt cylinder 14T may allow lifter 14F to assume a wide range of positions for working with lifter 14F at different tilt angles.
  • Cylinder 14C moves lifter 14F in a transverse direction (perpendicular to the rail direction) along shaft or axle 14A (see Fig. 16) relative to the assembly 58. Therefore, this allows transverse positioning of the ' lifter 14F independent of the transverse positioning of the undercutter 12F to achieve the various modes of operation discussed above.

  • Assembly 56 is moved transversely (pependicular to the rail direction) by one or more cylinders 56C (only one shown) . This allows transverse movement of undercutter 12F and lifter 14F in unison in addition to their discussed independent transverse movement.
  • the undercutter 12F is powered by motor 12M and pivotally attached to carriage 62 at pivot axle 12P.
  • Undercutter 12F is rotated about the vertical axis corresponding to 12P by cylinder 12C attached to plate 62P (anchored to carriage 62) and to a vertical bar 12B extending up from the undercutter 14F.
  • Cylinder 12C allows undercutter chain mechanism 12F to move between a position parallel to the rails and a position perpendicular to the rails.
  • Wheels 22R may move from their work position shown to travel position 22R' (Fig. 3A only) by operation of cylinder 22C moving wheel mount carriage 22M to which wheels 22R are mounted.
  • Carriage 22M may slide horizontally relative to main frame 10F by a system similar to that used for carriages 62 and 64.
  • the wheels 22R remove much of the vehicle weight from the area where undercutter 12F is removing ballast. In that fashion, the rails will be deflected downward less than would otherwise be the case.
  • the wheels in their 22R' position are sufficiently close to the rear of the vehicle to have the handling characteristics in normal travel (i.e., when not digging or undercutting) required in some countries and to more evenly distribute the weight between front and rear wheels.

Abstract

Une dégarnisseuse enlève le ballast d'une voie de chemin de fer à l'aide d'une ou plusieurs chenilles de dégarnissage (12F, 12S) et d'un ou plusieurs mécanismes de levage ou de creusement (14F, 14S) à chenille qui peuvent être positionnés de manière indépendante pour permettre différents modes de fonctionnement destinés à éviter différents types d'obstacles. Le mécanisme de levage à chenille utilise une roue supérieure d'entraînement à une extrémité supérieure et trois roues libres à son extrémité inférieure. Un système d'acheminement (16F, 18, 20F, 20S) situé sur le véhicule permet de transporter le ballast usé ou ancien vers l'avant droit, l'avant gauche, le côté ou l'arrière du véhicule.
