Definitions

  • MOBILE TRACK CORRECTING MACHINE Fil ed Jan. 12, 1966 Sheet 2 of 5 I N VEN TORS 5 PM).
  • the frame of a mobile track liner carries a means for exerting a lateral thrust against a selected rail, and an elongated element extends between the rails to receive the back pressure of the lateral thrust.
  • One end of the thrust receiving element is connected to the machine frame and its other end to a truck arranged on the track at a point spaced from the machine frame.
  • the present invention relates to mobile track correcting machines, particularly the type of mobile track tamper carrying means for lifting the track and laterally moving the same so that the machine may be used for track lining and grading.
  • a track section is continuously graded and/or lined by moving the machines along the track section.
  • the machine has a front and a rear axle, with a front portion of the machine frame preferably extending forwardly of the front axle and thus overhanging a track section to be corrected while the heavy machine itself rests with its front and rear axles on a previously corrected track section.
  • support jacks on this front portion laterally outside the track and designed to support the front portion on the ballast 'bed while the track is lifted and/or laterally moved.
  • the front axle of the above-described type of machine lies relatively closely to the track correction point and the lateral thrust on the track may be so large that the track under the front axle and even as far back as the rear axle may be moved thereby, thus disturbing the previous correction of this track section. If the track is corrected at a point between the machine axles, this difficulty is avoided but, on the other 3,425,360 Patented Feb.
  • the thrust exerting means is mounted on the machine frame and the thrust receiving means is an elongated element extending between the track rails, with the thrust exerting means positioned between one of the track rails and the elongated element.
  • One end of the elongated element is preferably pivotally connected to the machine frame and the other end of the elongated element is preferably pivotally and detachably connected to a truck arranged on the track at a point spacedfrom the machine frame.
  • the lateral thrust is exerted against a selected one of the rails for moving the track in a desired lateral direction.
  • the back pressure of the lateral thrust is not transferred indirectly to the ballast bed by the support jacks which constitute a labile support for the heavy front portion of the machine frame but this pressure is transmitted by the elongated element to the track, with which the truck and the machine solidly connect it, and from the track to the ballast bed on which the track rests.
  • This transmittal of thrust takes place at points sufficiently removed from the track correction point to remain uninfluenced by the correction operations, the elongation of the thrust receiving element being such that its ends are relatively far removed from the track correction point. Best results will usually be obtained if the lateral thrust exerting means is mounted about centrally between the ends of the thrust receiving element although variations of the spacing may be effected, according to individual operating conditions.
  • the lateral thrust exerting means may be arranged nearer the latter than the former end.
  • the one endjof the elongated thrust receiving element may be connected to the machine frame at its front portion, near the front axle of the machine or even between the axles of the machine but, under all circumstances, the element must be long enough so that its other end is sufficiently far removed from the track correction point to remain uninfluenced by its movements.
  • a spatial framework which may include a lower and an upper truss.
  • FIG. 1 schematically shows a side view of a mobile track correcting machine according to one embodiment of this invention
  • FIG. 2 is a top view of FIG. 1;
  • FIG. 3 is a schematic front view, partly in section, of the track lifting and aligning means

  • FIGS. 1 to 3 there is shown a mobile track correcting machine including a frame 1 mounted on truck 2 carrying the front axle and truck 3 carrying the rear axle of the machine.
  • An elongated thrust receiving element 5 has a pivot 6 at one end and a pivot 8 at the other end, the pivot 6 pivotally connecting the one end to a front portion of the machine frame 1 for pivoting the element about an axis extending perpendicularly to the track and in a plane extending substantially parallel thereto, and the pivot 8 being forwardly spaced from the frame 1 and pivotally connecting a truck 7 to the other end of the elongated element for pivoting the truck 7 about a like axis and in a like plane.
  • Lateral thrust is exerted upon the track 4 in the direction of selected rail 18 by a hydraulic motor 9 mounted on the front portion of the machine frame on each side of the thrust receiving element and arranged to bear against the element 5 as well as rail engaging clamps 10, 10, to which the rails 18 of the track may be mechanically or magnetically clamped in any conventional manner, so that selective operation of the one or other hydraulic motor will cause the track to be moved laterally in the one or the other direction.
  • the track includes ties 19 and, as best shown in enlarged FIG. 3, the illustrated rail clamps are mechanically operated jaws carrying rollers continuously engaging the rails and clamping the same therebetween while the machine advances along the track.
  • the hydraulic motors 9 constitute lateral track moving means and are linked to the element 5 and to the rail clamping means.
  • Equally conventional hydraulic motors 11, 11 are linked respectively to the front portion of the machine frame 1 and rail engaging clamps 10, 10 for lifting the track so that the track may be graded as well as laterally aligned during the correction operation.
  • the corrected track is fixed in position -by track tampers 12, the track tamping means being mounted vertically adjustably in a known manner in the front portion of the machine frame extending forwardly of the front axle of the machine.
  • Grading is effected in a known manner in relation to reference line 13 extending above each rail from a point forwardly of, and spaced from the machine in an ungraded track section to a point backwardly of the front axle in an adjacent, previously graded track section.
  • the reference line 13 is a beam of radiated energy, such as a light beam generated at one of the points and received at the other point.
  • the beam sender (or receiver) 14 is shown mounted on a front bogie 15 while the receiver (or sender) 16 is mounted in the machine frame 1 on a vertical support rod resting on a respective one of the rails.
  • a stop 17 is fixedly mounted on the overhanging front portion of the machine frame in the range of a vertical plane passing through the track lifting means and, as is well known in this type of track grading, when the stop interrupts the light beam 13 upon lifting of the track and the machine resting thereon, the hydraulic motor 11 is halted so as to discontinue lifting of the track.
  • the forwardly extending thrust receiving element 5 may be slightly lifted so that the front bogie 15 may be pulled in and carried on the element when the machine is driven from one place of operation to another, i.e., when it is not working on track correction.
  • FIG. 4 illustrates front bogie 15 carrying three senders (or receivers) 14, 14 of beams of radiant energy.
  • the sender (or receiver) 14 above the inner rail of the track section is used while the central sender (or receiver) 14 is used in straight track sections.
  • the configuration of support element 5 is such that it may be fitted into the frame of bogie 15.
  • the truck 7 may be detached from the forward end of support element 5 and the bogie may be moved onto the support element, being carried thereby while this element is slightly lifted (see broken line position in FIG. 1).
  • the detachable truck 7 may also have a frame fitting over the element 5 so that it may be similarly carried thereby when the machine is not operating but being driven from one operating site to another.
  • FIG. 7 In the modified apparatus of FIG. 5 and as more clearly illustrated in FIG. 7, like referenc numerals designate like parts operating in a like manner to avoid redundancy in the description.
  • Two reference lines 20 and 21 are schematically shown to extend laterally spaced from the track and capable of forming chords of different lengths in an arcuate section of the track to be aligned. Many such curve alignment methods have been developed and the present invention is not concerned with any particular aligning method but may be applied to all of them.
  • the forward truck 7 on element 5 serves as the forward anchor point of the reference lines if element 5 is of sufficient length, thus eliminating the need for special trucks for this purpose.
  • vertically movable truck 23 mounted in a rear portion of the machine frame 1 serves as the rear anchor point of the longer reference line 21, thus establishing a sufficient length of this reference line to assure accurate alignment in respect thereto, the front anchor point lying in a track section to be aligned and the rear anchor point lying in the previously aligned track section adjacent thereto. If the rear truck 23 is vertically movably mounted on the machine frame, it may be raised out of engagement with the track when the machine is not used for track alignment.
  • An intermediate truck 22 is mounted on thrust receiving element 5. It is similar to truck 7 and, when not in use, may be similarly mounted on the element 5 out of engagement with the track.
  • One or more such intermediate trucks may be mounted on the elongated element 5 to constitute intermediate reference or anchor points at which, for instance, the arc height may be measured.
  • various curve aligning methods using chords and are heights are known and the invention is not concerned therewith.
  • the illustrated machine may be structurally modified in many Ways wihout changing the essential function thereof, as described herein.
  • the lateral track moving means 9 may be arranged substantially centrally between the support element ends 6 and 7 whereby the lateral thrust during movement of the track is transmitted to the track equally at both ends of the element 5.
  • This backward extension of the element 5 to the front axle is shown in dotted lines in FIGS. 2 and 5.
  • the track moving and fixing means 9, 11, 12 need not be mounted in an overhanging front portion of the machine frame, as illustrated, and the rear end of the element 5 may extend even beyond the front axle of the machine as far back as its rear axle.
  • FIGS. 6-10 The embodiment of FIGS. 6-10 is similar in many respects to that of FIG. 5, like reference numerals being used to indicate like parts operating in a like manner so as to eliminate redundancy in description.
  • the thrust receiving element 5a includes a hinge means 5, 5" (see FIG. 8) arranged intermediate the ends 6 and 7a of the element so that the forward portion of the element 5a may be pivoted upwardly in the manner shown in broken lines in FIG. 6 about a horizontal axis, thereby making its length extending along the track variable.
  • the element 5a is constituted by a framework and the lower truss of the framework carries the pivot 5 with a horizontally extending fulcrum about which the framework may be swung upwardly.
  • the upper truss of the framework carries a removable bolt 5" to fix the element 5a in its horizontal or upwardly extending position, as indicated in broken lines in FIG. 8.
  • the upper truss carries suitably registering bores in the vertical plane of the pivot 5' to receive the bolt for fixing the support element in its horizontal position.
  • FIG. 10 shows a specific embodiment of front truck 7a wherein rail clamps 7" are movable into engagement with the rails by hydraulic motors 7
  • the shorter chord s, designated 20, and the longer chard S, designated 21 are parallel chords in a circularly arcuated track section extending from a previously aligned section behind front axle 2 to an adjacent track section to be aligned between the front axle and forward anchor point 8.
  • the long chord extends from point 8 to a rear truck 22a which is coupled to the rear end of the machine frame at a chosen distance therefrom.
  • the forward end of the shorter chord is at the point of the track moving means 9, 10, where the track is to be aligned, and this chord extends to the rear truck 23 mounted on the machine frame.
