Definitions

  • a universal tam g per comprises a track leveling and hn- [58'] Field of Search 7 7 105/393 ing tool mounted between the front and rear axles of [56] t (ed an elongated machine frame. The distance of the front e erences axle from the track correction tool and the rear axle is UNITED STATES PATENTS variable.
  • the tamper has a reference system for the f r v track correction.
  • the present invention relates to a mobile track correction and tamping machine, preferably usable for track leveling and lining.
  • Machines of this type have been built with an elongated machine frame supported for mobility on the track on a front and rear axle or running gear, the distance between the front and rear axles providing a long. wheel base.
  • Track tamping as well as correction means including track lifting and preferably lining means may be mounted on the machine frame between the front and rear axles, and a reference system is provided for the track correction.
  • the track tamping and correction means were usually mounted about equidistant between the machine axles or running gears.
  • the machine frame had to have a certain minimum length to make it'possible to lift the track sufficiently by track lifting means mounted on theframe and without counter-support on the ballast because the maximal lifting stroke is necessarily determined by the distance of the machine axles, i.e'. the distance of those track points which are pressed downby the heavy weight of the machine from the track point where lifting is effected therebetween.
  • Howevenan excessive length of the machine frame has certain disadvantages, such as'a wrong position of the track correction means in track curves, sagging of the longframe between the axle supports, and a difficult maneuverability of the machine.
  • the track lifting means in track tamping-leveling machines on a front portion of the machine frame freely overhanging the track section to be leveled'or graded. Since the track section being lifted is free of any weight in such machines, the lifting stroke is in no way limited as long as the track lifting means is sufficiently spaced from the front axleof the ⁇ machine whence the overhanging machine frame portion extends.
  • this type of tamper has various disadvantages compared to the first-described type of machine.
  • the tamping and track correction means mounted on the machine frame between the axles thereof, the weight of the machine is better and more evenly distributed over the track section to' be corrected, thus avoiding excessive correction movements of the track which may be produced in a freely moving track section and are prevented when this track section is pinned down, as it were, at its end points determined by the two machine frame axles.
  • Track deformations due to the correction movement are particularly prevalent at high temperatures which make the rails more flexible.
  • the track correction means is mounted between the axles, the track rails cannot move ahead or behind the correction point, and a more accurateand longer-lasting track correction is made with such a machine.
  • front and rear designate a position in relation to the working direction of the machine along the track elongation.
  • the track tamping means is mounted on the machine frame closer to'the rear than the front axle or running gear so that, as in'the machine type with the overhanging machine frame front portion, the track immediately behind the tamping is held down firmly by the machine weight resting on the rear axle.
  • the distanceof the front axle from the rear axle and the track correction means may be varied in different ways.
  • the front axle- is longitudinally adjustably mounted on the machine frame for this purpose.
  • it may be structurally simpler to provide a second front axle longitudinally spaced from the first mentioned front axle.
  • At least one of the front axles may then be vertically adjustable out of engagement with the track so that only a selected front axle supports the frame for mobility on the track, the distance between the front and rear axles depending on which front axle has been selected.
  • Either the foremost or the other front axle may be vertically adjustable. It is essential in either case that the selected front axle is an axle capable of bearing the load of the machine frame, and carries this load when selected to engage the track.
  • means is preferably provided for mechanically retaining the vertically adjusted front axle in an adjusted vertical position.
  • a double acting hydraulic jack constitutes a useful vertical adjusting and retaining means.
  • FIG. 1 is a schematic side view of one embodiment of a machine according to this invention
  • FIG. 2 is a top view of FIG. 1;
  • FIGS. 3 and 4 are views similar to that of FIGS. 1 and 2 of another embodiment.
  • FIG. 5 is a schematic side view, on a smaller scale, of yet another embodiment.
  • FIGS. 1 and 2 there is shown an elongated machine frame 1 supported-for mobility on the track by two of three axles or running gears, i.e rear axle 2 and a selected one of front axle 3 or 4, front axle 4 constituting the foremost axle of the machine.
  • a schematically indicated, vertically adjustable tamping unit 7 for tamping a tie is mounted on the frame 1 immediately in front of the operators cab 6 and closer to the rear axle 2 than to either one of the front axles.
  • a track correction means 7 is mounted on machine frame 1.
  • the track correction means includes a conventional unit of two pairs of roller clamps 8 per rail, the roller clamps moving directly under the head of the rails and gripping the same glidingly at two points.
  • the unit of rail engaging roller clamps is operated for track lifting by a hydraulic jack 9 and for track lining by a hydraulic jack 10, as is conventional.
  • the machine includes a conventional reference system for leveling and for lining the track.
  • This system comprises a light beam 14 controlling the track. leveling, the sender ll of the light beam being mounted on the track in the region of the front axle of the machine and the light beam receiver 12 being mounted in the region of the rear axle on a previously corrected track section.
  • a light masking or intercepting stop 13 is mounted on the track in the region of the track correction.
  • Two tensioned chords 14 and 15 are part of the reference system for controlling the track lining by the well known two-chord lining system.
  • the shorter wire 15 and the longer wire 16 constitute chords in an arcuate track section and serve as reference lines for the lining.
  • Short chord 15 extends between bogies l7 and 18, and long chord 16 extends between bogies l7 and 21, the bogies moving on the track with the machine and the distance between bogies l7 and 18 being fixed.
  • the front bogie 21 is arranged in the region of the front axle and is movable independently thereof, at a fixed distance from the other bogies.
  • the rear bogie 17 is connected to the machine frame by a telescoping spacing rod 19 so that its distance from the machine may be varied.
  • chords pass a measuring bogie 12' in the region of receiver 12 so as to determine the actual ordinate of the track by means of long chord l6 and to transpose it into the desired ordinate for the lined track by means of short chord l5, chord probes being provided at the measuring point in the manner fully described in our U. S. Pat. No. 3,314,373.
  • the track lining unit 8 at the front end of the short chord 15 moves the track laterally until the actual ordinate at this point corresponds to the desired ordinate determined by the long chord 16, at which time operation of jack 10 is stopped. At this point, the track is also lifted by operation of jack 9 until the mask 13 intercepts the light beam 14 to produce a light reference line parallel to the desired track level, which line produces a control signal at receiver 12 to interrupt operation of jack 9. Since the track leveling and lining reference system is known, it has been described herein only sketchily.
  • the light beam sender 11' may be mounted in alignment with the center line of the track and emit two divergent light beams received at a pair of receivers 12, 12 each associated with a respective track rail.
  • sender 11' may be associated with each track rail.
  • Each sender may then cooperate with a respective receiver or, in track curves, only the sender and receiver associated with the grade rail are operated.
  • the distance of the front axle or running gear supporting the machine frame 1 for mobility on the track from. the track correction means 8 and the rear axle or running gear 2 is variable.
  • this distance variation is effected by two. front axles 3 and 4 longitudinally spaced from each other so that they have different distances from the track correction unit 8 and the tamping unit 7.
  • the foremost front axle 4 is vertically adjustable on the machine frame by means of a double-acting hydraulic jack 4'.
  • the axle When moved down into engagement with the rail, the axle willsufficiently lift the frame to disengage axle 3 from the rail, as shown, so that the frame rests solely on axle 4 which is retained in the adjusted vertical position by means of a mechanical stop 4" so that the machine frame 1 solidly rests on track 5 with the front axle 4 when the same is vertically adjusted into engagement with the track while the track correction means is operated.
  • the distance of the foremost front axle 4 from the unit 8 and rear axle 2 may be further varied by mounting the foremost axle 4 on a longitudinally extending guide rail 20 on an extension of the frame 1 for movement of the axle 4 in the direction of track elongation, as indicated by the double-headed arrow.
  • the frame When the foremost axle 4 is vertically retracted out of engagement with the track, the frame rests solely on front axle 3, which becomes the foremost axle, and whose distance from the unit 8 and rear axle 2 is less than the distance therefrom of front axle 4 which, when in engagement with the track, .solely supports the frame.
  • the sender ll of the light beam forming part of the reference system may be mounted on the foremost front axle 4 for longitudinal movement therewith.
  • the anchor 21 of the longer chord 16 must remain fixed in relation to the other anchor of this chord so that the length of the chord remains constant, which is a condition for the two-chord lining system.
  • FIGS. 3 and 4 show. another embodiment for the distance variation of the foremost front axle supporting the machine frame 1 for mobility on the track.
  • the front axle or running gear 3 between the foremost front axle or running gear 4 and the track correction unit 8 is vertically adjustably mounted on the machine frame into and out of engagement with the track, this adjustment being effected by double-acting jack 3'.
  • the front axle 3 is retracted, the machine frame 1 is supported solely by the foremost front axle 4.
  • a carrier 28 for the foremost front axle 4 which carrier is telescopingly mounted on the front end of the machine frame 1 for extension in the direction of track elongation.
  • the front axle 4 is mounted for longitudinal movement on guide rails on the-carrier 28.
  • the reference system for lining the track comprises only a single reference line 22 extending alongside the track at one side thereof, this reference line consisting of a light beam extending between a sender (or receiver) 23 and a receiver (or sender) 24.
  • a light beam mask or stop 23 is laterally movable with the track into the path of the light beam 22 to control the lining in a manner similar to the level control ;by mask 13.-
  • the light beam end station 24 is mounted on a bogie 26 which is inountedon the outer end of longitudinally adjustable carrier 28 so that its distance from the machine frame may be varied;
  • FIG. '5 ' shows a modification of theembodiment of FIGS. 3 and 4 but uses'an independently driven front carriage'29 supporting the front end of the leveling and lining reference system.
  • the frontcarriage 29 may be driven by remote control, for instance by control signals generated by lining reference light beam 22 or leveling reference light beam 30. In this manner, the front carriage 29'may be driven to so-called high points in the uncorrected track section to 'provide good reference points for the track correction operation in a manner well known per se.
  • the remote control'of the front carriage drive makes it possible to send the front carriage a long way ahead of the track correction and tamping machine to obtain long reference lines which are advantageous in compensating for errors in the position of the end points of the reference lines.
  • the remote control may also be used, of course, to drive the front carriage close to the machine at the end of the track work, for instance.
  • reference light beam30 extends between a receiver (or sender) 31 on the machine frame 1 and a sender (or receiver) 27 on the front carriage 29, which reference line 30 serves to control the vertical position of sender ll of light beam 14 which serves as leveling reference. Provision of the added reference line 30 avoids faulty positioning of the end station 11 of reference line 14 because of a faulty level of the track section at this point. Thus, the accuracy of the leveling operation will be considerably increased.
  • a mobile track correction and tamping machine comprising 1. an elongated machine frame;
  • a front and a rear axle supporting the frame for mobility on the track, a a. the distance between the front and rear axles providing a long wheel base, and
  • track correction means including track lifting means mounted on the machine frame between the front and rear axles,
  • the mobile track correction and tamping machine of claim 1 further comprising afront and a rear bogie supporting the reference system, the bogies' being movable on the track with the machine frame and being connected thereto at a variable distance.
  • a mobile track correction and tamping machine comprising 1. an elongated machine frame;
  • first front axle a first front axle, a second front axle and a rear a. the second front axle being longitudinally spaced from the first front axle,
