Definitions

  • the present invention relates to track grading and more particularly to improvements in the type of track grading operations wherein adjacent track sections are continuously graded with a mobile track grading apparatus whose operating movements are fully automated in a generally known manner.
  • a reference line extends preferably above each rail of the track from a point above a previously graded track section forwardly over an adjacent track section to be graded.
  • a support advantageously constituted by a mobile track tamping and lifting machine with wheels arranged for movement on the graded track section carries means forwardly of the wheels for raising the rails of the adjacent track section to a grade determined by the reference line or lines.
  • a control element is supported on the adjacent track section whereby the control element is raised with the raising of the associated adjacent track section rail.
  • the control element usually includes a spotboard having an upper edge and contact between this upper edge and the associated reference line automatically interrupts the raising of the associated rail, thus determining the grade of the adjacent track section rail.
  • the reference line may be constituted by a beam of radiated energy, such as visible light, infrared radiation or other electromagnetic energy, by a tensioned wire, which may be an electrical conductor, or any other suitable means constituting a straight line.
  • the rail raising means may include any suitable jack or a rail gripping mechanism connected to an electrically operated hydraulic motor.
  • contact of the upper edge of the spotboard with the reference line i.e. closing of an electric circuit constituted by the upper spotboard edge and an electrically conductive tensioned reference wire, or interruption of the radiated energy beam by movement of the upper edge across the beam, may instantly stop operation of the hydraulic motor and thus the raising of the rail.
  • each rail is raised independently in respect of an associated reference line until an upper edge of an associated one of the control elements contacts the associated reference line and the superelevation of the track is measured after the rails have been raised, most simply by a transversely extending level.
  • FIG. 1 is a schematic side view of a generally conventional grading apparatus showing only those portions of the apparatus directly cooperating with the improvement of this invention
  • FIGS. 2, 3 and 4 are enlarged side views, partly in section, of three specific structural embodiments of a spotboard useful for the practice of the invention.
  • the mobile track grading apparatus is shown to comprise a support 1 having wheels 2 arranged for movement on rails 3.
  • the wheels move on a graded track section and means is mounted on support 1 forwardly of the wheels for raising the rails of a track section adjacent to the graded track section.
  • One such rail raising means is associated with each rail and each includes rail gripping elements 5 which may be lifted by hydraulic motor 4.
  • the reference line 6 of the illustrated embodiment is a beam of electromagnetic energy, such as a light beam, extending above each of the rails 3 from a point 10 above the graded track section forwardly over the adjacent track section to be graded.
  • a bogie 7 is arranged on the track in advance of the track grading carriage 1 and carries a transmitter 8 of beam 6.
  • a beam receiver 10 constitutes the end point of the reference line 6 above the graded track section and is supported on the other end of the vertically extending support element 9 whose one end is supported on a rail 3 of the graded track section.
  • the element 9 is a rod which is vertically slidably mounted in a bearing on support 1 and rests with a shoe on rail 3.
  • the grading control element includes a horizontally extending support member 11 which is a bar whose one end is movably supported on rod 9 by means of a bearing sleeve sliding on the rod and whose other end supports a spotboard 13.
  • Support means constituted in the illustrated embodiment by vertically extending rods 12, 12" support the forward end of the bar 11 on the rail 3 in the portion of the track section to be graded. In this manner, the control elements 11, 13 is raised with raising of the track section to be graded.
  • the spotboard has an upper edge means and, in a manner well known per se and, therefore, not further described or illustrated, the hydraulic motor 4 is stopped and reds ing of rail 3 is accordingly halted automatically when the upper edge means of spotboard 13 passes through the plane of extension of reference line 6,such contact causing instant stoppage of the motor while the motor operates to lift the rail grippers S as long as the upper edge means of the spotboard is out of contact with the reference line.
  • the hydraulic motor 4 is stopped and reds ing of rail 3 is accordingly halted automatically when the upper edge means of spotboard 13 passes through the plane of extension of reference line 6,such contact causing instant stoppage of the motor while the motor operates to lift the rail grippers S as long as the upper edge means of the spotboard is out of contact with the reference line.
  • FIGS. 2 to 4 illustrate three of the numerous structures useful in accomplishing the object of the invention.
  • Many other structural embodiments will readily occur to the skilled in the art, the only requirement being to lower the contacting upper edge of the control element so that the lowered edge will cause instant continuation of the rail lifting operation without interruption in the continuously proceeding grading operation, as the apparatus advances from tie to tie along the track from the previously graded section into a section to be graded.
  • the errors in superelevation at any one tie will be quite small so that the additional lifting of the one rail and the corresponding extent of the lowering of the control element will be of minor dimension.
  • the error would become important if transferred and thus gradually increased from tie to tie without correction.
  • Such a continuing increase in an erroneously graded track is simply and effectively avoided with the apparatus and method of the present invention.
  • control element is shown to include a spotboard mounted at the forward end of support bar 11 and the upper edge means arranged for contact with reference line 6 includes a fixed upper edge on a first board 13" and a movable upper edge on a second board 13 movably supported on board 13".
  • the movable upper edge extends in a plane above the fixed upper edge in a first position (shown in full lines) of the second board 13'. In this position, the planes of the two upper edges are spaced by a distance x of quite minor length, which is determined by operating experience in the grading of like track sections.
  • the board 13' is mounted on means for moving this board so that the movable upper edge of the spotboard is below the plane of its fixed upper edge (see broken lines), the illustrated moving means being a pivot supporting the second board on the first board.
  • the spotboard 13 is pivoted to a bracket at the forward end of support bar 11, which bracket also carries a solenoid 14 for pivoting the spotboard into selected positions providing desired distances x of the upper edge of the spotboard from its upright position shown in full lines.
  • the selected positions of the spotboard and the corresponding position of the upper edge causing stoppage of the rail lifting operation in response to the contact of the upper edge with the reference line, may be controlled by an adjustable stop 15 also mounted on the bracket.
  • the spotboard 13 is mounted on a vertical guide rod 16 vertically adjustably supported on a bearing 17.
  • the vertical movement of the spotboard may be etfectuated by any suitable means, including solenoid means, hydraulic motor means or mechanical linkage means.
