Definitions

  • the present invention relates to improvements in measuring bogies used in surveying and/or correcting the position of a track.
  • Measuring bogies of this type comprise a running gear with a transversely extending carrier, a track surveying element fixedly mounted on the carrier, and two substantially coaxially mounted flanged wheels supported on the carrier, with each of the flanged wheels running on a respective one of the track rails and the flanges of the wheels in contact with the rails.
  • a remotely controllable drive such as a pneumatically or hydraulically operated cylinder-piston motor, presses the carrier by means of one of the flanged wheels transversely against a selected one of the rails serving as grade rail whereby the track surveying element on the carrier is held at a constant distance from the grade rail.
  • This object is accomplished in accordance with the present invention with a running gear of the indicated type, wherein the flanged wheels and the carrier are transversely movable in respect of each other, and the remotely controllable drive for pressing the carrier against the grade rail is connected, on the one hand, with the carrier and, on the other hand, with the other flanged wheel running on, and in contact with, the other rail for moving the other flanged wheel.
  • FIG. 1 is a schematic side view of a conventional track lining machine in connection with which the measuring bogies of the invention may be used;
  • FIG. la is a similar view of a conventional track leveling, lining and tamping machine whose reference system may make use of these measuring bogies;
  • FIG. 2 is a front view, partly in section, as seen in the direction of arrow II of FIG. 3, of a running gear used as a measuring bogie according to the invention.
  • FIG. 3 is a top view of the running gear.
  • a mobile track liner 1 which may operate in either direction, as indicated by the horizontal arrows, along track 2.
  • the machine frame runs on the track on wheels 3 and carries a track lining tool 4 intermediate the wheels, the lining tool engaging the track rails and being transversely movable to line the engaged track.
  • the reference system for the lining includes a reference line 5 extending between end stations 6, 6 connected to the respective ends of the liner frame by means of spacing rods 6', 6", respectively, the reference line passing intermediatestation 7 and measuring station 8 at the point of lining.
  • the reference line must be located at a constant distance from the track, i.e., its grade rail, for which purpose the running gears described hereinafter are positioned at stations 6, 7,
  • running gears are useful in any lining operation and regardless of the number of reference lines, the reference system and the lining operation will not be further described. As shown in FIG. la merely by way of further explanation, such running gears may also be used in other types of mobile track working machines or in any type of operation requiring a survey of the track position.
  • the combined track tamping, leveling and lining machine of FIG. la comprises a mobile frame 1' moving on track 2 by means of wheels 3', track lining tools 4 being mounted on the frame between the wheels. Lining is effected in relation to reference line 5'. A fixed point for the reference system is located at station 7' and the measuring station 8' is located at the track lining point. An overhanging portion of the frame carries track tampers 9 and track lifting tools 10, the track leveling operation being controlled by a reference system including a receiver 11 for a reference beam 12. The receiver rests. on on the previously leveled track and is carried by vertically movable rod 13 to indicate the desired level to which the tools 10 are to lift the track, leveling operations of this type being well known and requiring no further description for the purposes of the present invention.
  • the running gear of this invention may be used in this type of track correction apparatus to survey the track position and thus to form a part of the reference system for the lining operation.
  • FIGS. 2 and 3 A preferred embodiment of such a running gear is shown in FIGS. 2 and 3. It comprises a transversely extending carrier 18 provided with guide means consisting of guide sleeves 17, 17 for glidably mounting the stub axles 16, 16' of flanged wheels 14, 14 which are at least substantially coaxially supported on the carrier 18 and run on a respective track rail 15, 15', with the flanges of the wheels in contact with the rails. In this manner, the flanged wheels and the carrier are transversely movable in respect of each other.
  • a bracket 19 carrying a track surveying element 30 is fixedly mounted on carrier 18.
  • the track surveying element consists of a pulley and a tensioned wire 5 serving as a reference line is trained over the pulley 30. Since the reference line serves as the datum for the track position, the end point 30 thereof must be held at a constant distance from the selected grade rail.
  • the tensioned wire passes from pulley 30 over guide roller 21 to wire tensioning reel 31 which may be turned by handle 23 and, when the wire has been tensioned, may be held against rotation in a known manner to keep the wire under tension.
  • the tensioning reel 31 is mounted on bracket 18a which is fixedly mounted on carrier 18. If desired, brackets 18a and 19 may be integral with the carrier, the brackets in any case forming part of the carrier.
  • the illustrated remotely controllable drive of the present invention consists of two like hydraulically or pneumatically operated motors each consisting of a cylinder 20, 20', a piston 21, 21', a piston rod 22, 22', and a pressure fluid conduit 20a, 20a. Since pressure fluid operated motors of this type are very well known, the structure is only schematically indicated and their operation requires no further description. It is equally obviousthat the two cylinder-piston motors could be replaced by a single double-acting cylinder-piston motor functioning identically. Furthermore, the drive may be a magnetically, electromagnetically, electrically or mechanically operated motor of any suitable type which may be remote controlled.
  • the two separate drives are arranged laterally adjacent the track surveying element 30, and the track surveying element is mounted intermediate the wheels 14, 14.
  • the cylinder of each drive forms a fixed part thereof while the piston rod and piston of each drive constitutes a movable part of the drive.
  • the fixed cylinders are linked to the carrier bracket 18a at pivots 19, 19 while the free outer ends of the piston rods 22, 22' are linked respectively to one end of guide levers 24, 24'.
  • the guide levers are pivoted intermediate their ends to stops 25, 25 respectively, while the other ends of the guide levers are linked to brackets 23, 23, respectively, which are mounted on carrier 18.
  • the stops 25, 25 are constituted by bushings fixedly mounted on, or integral with, stub axles 16, 16 of the flanged wheels, these bushings being laterally adjacent the carrier 18.
  • the present invention is not limited to the illustrated connection of driving parts to the flanged wheels.
  • the drive is connected indirectly, on the one hand, with the end of carrier 18 to be pressed against the grade rail and, on the other hand, with the flanged wheel opposite to this end for pressing the carrierwith its track surveying element against the grade rail while simultaneously holding the opposite flanged wheel in contact with the opposite rail.
  • the position of the drive is indicated in full lines with the assumption that the right outward pressure of the piston rod 22 which is indirectly connected to stop 25 will hold the stop in position so as to maintain the contact of flanged wheel 14 with rail 15, the stop 25, stub axle l6 and wheel 14 forming a unit.
  • the counterpressure of the pressure fluid in the right-hand chamber of cylinder 20 will exert a pressure against the carrier bracket 18a to press the same with the carrier towards the right.
  • Carrier 18 being transversely movable in respect of the stub axles 16, 16, the rightward movement of the carrier will bring its right end into engagement with stop 25' of stub axle 16.
  • the carrier and track surveying element 30 are moved into the position shown in full lines in FIG.
  • any suitable remote controlled drive may be used and the motion-transmitting means from the drive to the flanged wheels and the carrier may take any desired form.
  • a running gear for surveying the position of a track comprising 1. a transversely extending carrier,
  • a remotely controllable drive for pressing the carrier together with one of the flanged wheels transversely in the direction of a selected one of the rails serving as a grade rail, whereby the track surveying element on the carrier is held at a constant distance from the grade rail, and for holding the other wheel in contact with the other rail, and
  • the running gear of claim 1 further comprising a stub axle carrying each of said flanged wheels, substantially coaxial guide means on the carrier for glidably mounting the stub axles on the carrier, and said drive being connected to the stub axles.
  • the'motiontransmitting means comprises a stop fixedly mounted on each of said stub-axles, the stops being laterally adjacent the carrier, the drive pressing the carrier transversely against the'stop on the stub axle of the one flanged wheel while holding the other flanged wheel in contact with the other rail.
