Definitions

  • drive motors are provided for automatically adjusting the [58] Field of vertical position of each beam transmitter independently.
  • the drive motors are operated in response to any deviation of the track from the horizontal, taking into account the different between the actual and the desired superelevation.
  • Known apparatus of this type comprises vertically adjustable radiated energy beam transmitters associated with the respective track rails, each transmitter emitting a reference beam, for instance of visible or infrared light above the respective rail, and means for surveying the superelevation of the track associated with the transmitters.
  • a radiated energy beam receiver is associated with each rail and is mounted thereabove at a constant distance therefrom, each receiver being arranged to receive a respective referencebeam, and radiated energy beam stop means is arranged in the path of each reference beam a shortand constant distance from each receiver, each stop means being associated with a respective rail and being mounted thereabove at a constant distance therefrom.
  • the reference plane defined by the two reference beams is always substantially parallel to the track plane, including in superelevated track curves, so that the reference beam stop means and receivers, which are positioned in the corrected track section, require no vertical adjustment, such adjustment being limited to the transmitters which are positioned on a front bogie in the uncorrected track section.
  • Each automatic means includes a drive motor for effectuating the vertical distance adjustment, a control means operatively connected to the drive motor for actuating the motor in response thereto, and means indicating the desired superelevation of the track.
  • the control means is responsive to the superelevation surveying means and is operatively connected to the desired superelevation indicating means whereby the drive motor automatically adjusts the vertical distance of the transmitter associated therewith in response to the desired superelevation and automatically takes into account the difference between the surveyed and desired superelevation.
  • the transmitters emit the reference beams without the occurrence of any superelevational errors at the track section where the transmitters are positioned, the required vertical adjustment means being simple and assuring high accuracy as well as maximal operational speed.
  • This au' tomatic positioning control of the transmitters eliminates not only the emission of incorrect control signals for the grading operation, i.e., the raising of the track, but also reduces the grading control steps executed by the machine operator, thus increasing the efficiency of the operation.
  • the deviation of the track from the horizontal may be indicated, i.e., the superelevation of the track may be surveyed, by means of a pendulum which swings in a vertical plane transverse to the track, and the control means comprises contacts indicating the extent of the deviation arranged in the path of the swinging pendulum.
  • a control circuit connects a respective contact to a respective drive motor for actuating this motor when the pendulum contacts the respective contact.
  • an adjustment means is operatively connected to the means for indicating the desired superelevation to set this means to a selected superelevation.
  • a control circuit leads from the operating and control stand in a corrected track section to the adjustment means for remote control thereof.
  • a superelevation indicator at the control stand is operatively connected to the remote controlled adjustment means for adjusting the desired superelevation in relation to the indicated superelevation so that the set values of the desired superelevation in the uncorrected track section may be compared with those of the indicated superelevation in the corrected track section.
  • FIG. 1 is a schematic top view of the essentialparts of a mobile track surfacing apparatus according to the present invention
  • FIG. 2 is a schematic transverse section along line "-11 of FIG. 1;
  • FIG. 3 is a perspective view of the essential parts of the apparatus in diagrammatic fonn.
  • FIG. 4 is a schematic transverse section along line IV--IV of FIG. 3, the front bogie being diagrammatically shown somewhat similarly to FIG. 2.
  • the generally conventional mobile track surfacingapparatus is shown to include a main carriage l, a front bogie 2 and a spacing rod 3 coupling the front bogie to the main carriage at a constant distance therefrom, the working direction of the apparatus being indicated by arrow 4 as the apparatus advances on rails 5, 5
  • the front bogie 2 supports radiated energy beam transmitters 6, 6' associated, respectively, with rails 5, 5 and emitting reference beams 14 and 14' or 14''.
  • Independent automatic means 9, 9 for adjusting the vertical distance of each of the transmitters from the associated rail independently of each other include drive motors 7, 7' rotating spindles 8, 8 for moving the transmitters up and down.
  • Useful motor-driven vertical adjustment means for this purpose are shown, for in stance, in our U.S. Pat. No. 3,198,135, dated Aug. 3, 1965, which is arranged to operate in response to a sensed su perelevation.
  • the front bogie 2 also carries a pendulum means 23 for surveying the superelevation of the track.
  • a control means 10 for actuating the drive motors is operatively connected to the motors and comprises two contacts constituting means indicating the desired superelevation and being arranged in the path of the swinging pendulum, and an electric control circuit-connecting the contacts to the drive motors for actuating a respective motor when the pendulum contacts a respective contact so that it may be vertically moved by rotation of the spindle either in the direction of arrow 11, 11 or 12, 12'. This adjustment takes into account the difference between the desired set superelevation and the sensed superelevation.
  • the main carriage 1 supports receivers 15, 15 sensitive to reference beams 14, 14 to produce operating signals used in a conventional manner for raising the track by means of jacks 16, 16, each receiver being associated with a respective track rail and being mounted thereabove at a constant distance therefrom.
  • stop means 17, 17' are arranged in the path of each reference beam in the region of the track raising and tamping point, i.e., a short and constant distance from each receiver and substantially closer to the receivers than the transmitters, movement of a stop means into the path of the associated reference beam discontinuing the operating signal and thus terminating the track lifting, as is well known.
  • An adjustment means 18 is mounted on the main carriage l at an operating and control stand and is operatively connected by means-of electrical control circuit 19 to the contacts of control means 10 for a remote control setting of the desired superelevation x which is determined by the setting of the contacts.
  • the combined track tamping and leveling machine incorporating the structure of the present invention advances over a track curve in the direction of arrow 4 from a previously graded track section 20 having a desired superelevation into a curve section 21 to be graded.
  • the main carriage 1 moves on the graded track section while the front bogie2 moves in the track section to be graded.
  • the track is lifted until the upper horizontal edge of stops 17, 17', which are mounted on the track at a constant distance therefrom, moves into the reference beams 14, 14 forming a reference plane which is substantially parallel to the plane of the track.
  • thestops prevent the reference beams from reaching the beam receivers, and as is well known in this type of track grading operation, actuation of the track lifting means is interrupted so that the graded track point assumes the position of the previously graded track section.
  • the free swinging pendulum 23 will contact one or the other of the set contacts 24, 24', which indicates the desired superelevation, thus closing the control circuit to drive motor 7' to rotate spindle 8 as long as the circuit remains closed to move the transmitter 6 vertically until such time as the pendulum no longer makes contact with the set contact 24 or 24', i.e., until the desired superelevation has been reached.
  • the contacts have been set beforehand by adjustment means 18 to the desired superelevation x.
  • the desired superelevation x is set in advance of entering the curve by remote control from the operating stand, and is constantly compared with the actual superelevation in the curve by means of pendulum 23, advantageous superelevation surveying means useful for this purpose being described in the above-mentioned US. Pat. No. 3,448,522.
  • the operator may use an additional control consisting of superelevation indicator 25 at the operating stand, which is preferably operatively connected to adjustment means 18.
  • the adjustment or setting of the desired superelevation indicating means 24, 24' at the reference beam transmitters may be constantly supervised by the actual superelevation indicated in the previously graded curve section 20.
  • the present invention has been described in connection with a combined tamping and grading machine wherein the frontbogie supporting the reference beam transmitters is arranged at a constant distance from the main carriage during the grading operation since it is of particular advantage in such asystem.
  • the structure of this invention in' connection with a self-propelled front bogie whose advance may be controlled so asto maintain the desired distance between the reference beam transmitter and receiver means.
  • this structure in connection with the type of machine which has a common frame moving on two running gears, with the tamping and track lifting means being mounted thereon between the running gears, the reference system being supported on the rails by rollers or the like.
  • the invention is not limited to any particular type of reference beam or plane or any particular transmitter and/or receiver means.
  • the particular arrangement of the superelevation indicating and surveying means on the front bogie may be varied.
  • the surveying means may be spaced from the indicating means in the direction of track elongation.
  • the transmitters may be so arranged that the desired superelevation may be indicated by manually setting the height of one of the transmitters associated with the grade rail while the-height of the other transmitter is then automatically adjusted in relation to the set transmitter.
