Definitions

  • the present invention relates to improvements in grading a track in relation to a reference line which is established from a previously graded track section to a track section to be graded, and which extends with a front end to a front station, this reference line being adjustable in relation to a longer control reference line extending with a front end to a stationary observation station remote from the front station.
  • track grading by means of two reference lines of different length produces a very smooth track grade over long distances, and prevents relative short successive track sections graded in relation to the short reference line to abut at angles. This is avoided by ad justing the height of the front end of the shorter reference line in relation to a control line which is much longer and whose front end lies in a track section to be corrected and which is remote from the front station of the shorter reference line, thus adjusting the position of the shorter reference line in relation to a long track section and producing smooth abutments of adjacent track sections being graded in relation to the shorter reference line.
  • the longer control line is constituted by a sight line established from a telescope at the stationary observation station towards a point, such as a horizontal marker on a spot board, fixed in relation to the previously graded track section on which the wheels of the track grading and tamping machine stand.
  • a front bogie runs ahead of the machine and carries the front station of the shorter reference line, and the vertical distance of the front station from the track rail is constantly controlled and adjusted by an operator at the observation station according to the present invention, while the front bogie moves towards the observation station.
  • the front end of the shorter reference line may be constantly adjusted in height if the front bogie travels over a low or high point of the track section to be graded.
  • Tracking grading systems of this general type make use of high points in the track section to be graded, where the front bogie is stationed so that the track grading machine 'may grade the track while advancing from a previously graded track section to this high point over the track section to be graded.
  • the front bogie is stationed so that the track grading machine 'may grade the track while advancing from a previously graded track section to this high point over the track section to be graded.
  • it happens occasionally that a high point in the track section .to be graded is reached by the front bogie relatively close to the track grading machine.
  • FIG. 1 is a side view of a track grading arrangement according to this inventon;
  • FIG. 2 is a top view of this arrangement, as indicated by arrow II in FIG. 1;
  • FIG. 3 illustrates the operation of this arrangement in grading a track section
  • FIG. 4 is a schematic front view of the track grading and tamping machine used in the arrangement of the invention, on an enlarged scale;
  • FIG. 5 is a schematic front view of the front bogie used in this arrangement, on the same scale.
  • a generally conventional mobile track grading and tamping machine N is shown arranged for movement on track G over a track section to be graded.
  • the track tamping and grading machine includes a frame 1 mounted on wheels 2 running on a previously graded track section immediately adjacent the track section to be graded.
  • a track lifting mechanism 5 mounted on the machine frame.
  • the lifting stroke is determined by a stop 6 which is mounted at a fixed distance from each track rail and cooperates with a reference line 7 spaced from each track rail by distance A.
  • the reference lines may be constituted in a preferred embodiment by a beam of electromagnetic waves, such as a light ray, and in a manner well known per se, the lifting of the track by hydraulically operated mechanism 5 may be discontinued when the stop 6 interrupts the light ray.
  • Each reference beam 7 runs from a rear station 8, which is mounted at fixed distance A above the previous ly graded track section, to a front station 9 mounted on the front bogie. If a beam is used as the reference line, either one of the stations may be constituted by a beam sender while the other station is a beam receiver. All of the above structures and their operations being well known, a further description thereof is not required for those skilled in the art to enable them to understand the same.
  • the front stations 9 of the reference lines 7 are mounted on the front bogie for vertical movement thereon, scales 9' being hung from each station to make it possible to read the vertical position of the stations above the track.
  • a spot board 10 is arranged at a fixed distance a from each stop 6, the spot boards being preferably mounted on a carrier arm extending downwardly from each stop.
  • Each spot board may be sub-divided by a horizontal line into a white and a black half, and the dividing line of the spot boards forms the back end of a second reference line which is much longer than the lines 7.
  • the front end of the longer reference line 11 is constituted by a surveying instrument, such as a telescope 12, which is vertically adjustably mounted on a portable or mobile support 13.
  • the front stations 9 of the shorter reference lines 7 are mounted on a carrier 20 which is supported for vertical movement in relation to bogie 14 by means of a vertical rod 20 which glides in guide 20".
  • a scale 15 is provided on the vertical rod in fixed spatial relationship to the front stations 9, and the rod forms part of a hydraulic motor 21 which may be operated by remote control by an operator at the observation station 12, 13 to raise or lower the front stations of shorter reference lines 7.
  • the front bogie 14 may be self-propelled, for instance by means of a motor which may be operated by remote control.
  • each front station 9 is individually vertically movable on the carrier 20 by means of hand wheels 18, their position being determinable by reading scales 19 associated with each front station. In this way, one rail may be lifted higher than the other rail of the track.
  • a fixed marker 15' is mounted on the front bogie in association with vertically movable scale 15.
  • Fixed marker 15 has a contact 22 and movable scale 15 has a contact 22, the two contacts forming a switch in an actuating circuit operating a signal.
  • the signal may be audible or visible, for instance, the preferred signal being a warning lamp 17 which lights up when the two contacts engage, i.e. when the zero marker scale 15 is below marker 15', which indicates the distance of the front stations of shorter reference lines 7 from the track.
  • the operator at the surveying instrument moves self-propelled front bogie 14 by remote control slowly into the adjacent track section to be graded. While he moves the bogie, he carefully watches through the telescope that the predetermined markers on pendulum scales 9' are in constant horizontal alignment with the horizontal sub-dividing line of the associated spot boards 10 so that the front stations 9 properly position the shorter reference lines 7. Since the track section over which the front bogie is moved is ungraded, this requires a constant control and adjustment of vertically movable carrier 20 by means of remote-controlled hydraulic motor 21.
  • warning lamp 17 lights up, the operator being thus informed of a high point of the track section even if he is fully occupied with watching the spot board 11 through telescope 12.
  • An audible signal may have the same effect.
  • the front end of the longer reference line 11, i.e. the telescope 12 may be vertically moved on support 13 until the telescope, the zero markers of the scales 9' and the horizontal dividing lines of spot boards 10 are in alignment when the carrier 1 20 with the front stations 9 of the shorter reference lines 7 has been vertically adjusted so that the marker 15 and the zero marker of scale 15 are in alignment and the latter zero marker is not below marker 15.
  • the vertical position of telescope 12 in relation to track G may vary within predetermined limits.
  • a method of grading a track rail in relation to a reference line extending vertically above the track rail comprising the steps of (1) establishing a first reference line from a previously graded track section to a track section to be graded and extending with a front end to a front station,
  • the longer reference line is a sight line established from the observation station towards a point fixed in relation to the previously grade track section, and the vertical distance of the front station is constantly controlled and adjusted in dependence of the sight line by an operator at the observation station.
  • a track-grading arrangement for grading a track rail comprising (1) a track grading machine with wheels movable on a previously graded track section,
  • a warning signaling device operative when the front station has reached a high point in the track section to be graded, which is above said plane.
  • the track grading arrangement of claim 4 further comprising means for vertically moving the front station on the front bogie, and the warning signaling device is mounted on the front hogie.
  • the vertical moving means includes a front station carrier vertically movably mounted on the front bogie, a scale and an associated marker making the vertical position of the front station carrier determinable, one of the scale and the marker being movable with the carrier and the other one being fixed in relation to the front bogie.
  • the track grading arrangement of claim 6, further comprising contacts connected to the scale and to the marker respectively, and electrical actuating circuit for actuating the warning signaling device, and said contacts forming a switch in said circuit for closing the same, the contacts being so positioned that the switch is closed when a zero marker on the scale is below the said marker.
  • warning signaling device is a lamp which lights up when the circuit is closed by said switch.
