Definitions

  • the invention relates to a measuring device for Measurement of geometric data of a track for rail vehicles, with a measuring carriage with on the upper running surfaces of the rail heads the Track rails rolling rollers and with to the insides of the Rail heads adjustable track rollers.
  • the object of the invention is the Kochfahrworth of Interruptions in a rail, in particular in the gap area of the frog a switch, an intersection or the like. Without special intervention of an operator to ensure.
  • This task is solved by the measuring carriage before and behind the track rollers in track longitudinal direction projecting guide bracket whose Length before or after the track rollers of the length of an interruption in one Rail at least corresponds.
  • the Guide bracket can be supported on the inside of the rail section, in the direction of travel of the measuring car behind the interruption in the rail starts before the inside of the rail section in front of the Interrupt rolling track roller reaches the break in the rail.
  • the next rail section then already fitting guide bracket This prevents the following track roll from crossing a relevant dimension is pushed to the rail longitudinal direction in the interruption by the Measuring carriage or the track rollers arranged thereon at least approximately be held and guided in the predetermined by the rails track.
  • the Guide bracket preferably with guide rollers for starting on the insides of the Rails, for example, on the insides of the rail heads or the Inner sides of the rail edges provided. Furthermore, it has to be advantageous proved when the guide bracket to their free ends obliquely inwards in run towards the rail space, for example, by turning it slightly inwards curved are designed.
  • the invention advantageously makes it possible to that the track rollers against the insides of the rail heads under bias can be adjusted, which can be done appropriately by at least one Spring arrangement is provided, which on at least one of the pairs arranged track rollers acts.
  • the arrangement is such that the guide brackets at the front and rear ends of the longitudinal direction located on the measuring carriage on both sides arranged guide skids, to which also the track rollers are mounted, whereby in the form of the guide skids as an assembly of guide brackets and tracking rollers existing arrangement laterally is pressed outwards against the rail inner sides.
  • the location of at least one of the track rollers by means a position sensor be determined.
  • the guide brackets are preferably arranged below the track rollers on the measuring carriage.
  • the way the track roller transverse to the rail longitudinal direction in the gap can be bordered by the assigned, projecting guide bracket is limited, it ensures that the track roller in contact on the front side of the following track section again reliably pressed inwards and on the inside of the Can start the rail head. As soon as the track roller returns to the Inside the rail head rests, are the guide bracket or from These worn guide rollers of the rail inside a piece removed and can not falsify the measurement result.
  • F ig. 1 is a simplified representation of the measuring device according to the invention in its arrangement on the rails of a track in a plan view;
  • Fig. 2 shows the subject of Figure 1 in a section along the line II-II.
  • the measuring device according to the invention in a highly schematic simplification in three different driving positions on the track rails in the region of a rail switch in plan view.
  • FIGS. 1 to 3 shows a guide blade of the measuring device according to FIGS. 1 to 3 in a side view
  • Fig. 5 shows the subject of Figure 4 in a plan view.
  • Fig. 6 shows the subject matter of Figs. 4 and 5 in section along the line VI-VI.
  • the whole in the drawing with 10 designated measuring device is used to measure geometric data of a Track 11 for rail vehicles, in particular for determining the gauge between the rail heads 12 of the two track rails 13.
  • the Measuring device 10 a measuring carriage 14 with on the upper treads 15 of Rail heads 12 rolling rollers 16 on.
  • the measuring carriage 14 is in the Essentially of two approximately U-shaped frame parts 17 and 18 formed with their frame inside projecting frame legs slidable together are connected. Between the frame legs of the two frame parts 17, 18 are preloaded helical compression springs 19 installed, which are the two frame parts Spread apart across the rail longitudinal direction 20.
  • the guide runners 22 project in the longitudinal direction of the track 20 in front of and behind the track rollers 24 via the measuring carriage 14 and form there forward and rear projecting guide bracket 25, where two each Guide rollers are mounted, whose axis of rotation parallel to the axes of rotation of the Track rollers 24 run. It can be seen that the guide bracket 25 to their free Ends 26 converge obliquely inward in the rail space.
  • the Length of the guide bar 25, measured between the at its outer, free Ends 27 mounted outer guide roller and the nearest one Track roller 24, is sized to fit the length of a break or a gap in a rail at least corresponds, as in a switch or a crossing in the track in front of the center of the so-called heart piece occurs where the outer rail of a branching track next to it Crossing rail of the trunk track crosses.
  • Such a gap 28 at the heart 29 of a switch 30 is shown schematically in Figs. 3A to 3C.
  • a arranged on the measuring carriage 14 Transmitter 31 processes the measured values that are not processed by one shown position sensor and which are a measure of the relative position the two frame parts 17, 18 to each other, and determines from this instantaneous gauge between the railheads.
  • Track rolling in the area of the gap 28 at the heart 29 of the switch comes the corresponding track roller due to the prevailing preload usually be pressed transversely to the track longitudinal direction in the gap and upon further movement of the measuring car to the heart center of the Accumulating the heart and thus cause a derailment of the measuring car.
  • This is due to the leading role of the relevant track roller guide bracket 25 and the rotatably mounted guide rollers prevents their way already past the gap 28 to the heart center subsequent track section 13 'have taken before the track roller of the inside of the rail head expires and of the spring in the gap 28th can be pushed in.
  • the two transverse to the rail longitudinal direction Frame parts of the measuring carriage apart-pushing spring force thus causes the guide bracket 25, which of the reaching in the region of the gap Track roller ahead runs, or arranged thereon guide rollers against the Inside the newly starting behind the gap rail section 13 'pressed and thus the track roller 24 if at all only a small piece across Rail longitudinal direction is pressed into the gap 28.
  • the track roller can thus easily back to the Inner side of the rail head of the adjoining rail section 13 ' start up and the measuring process can start immediately at the beginning of the subsequent Rail section to be continued.
  • the one ahead of the track roller Guide bracket with the guide rollers arranged thereon thus prevents Reliable accumulation of the measuring carriage on the heart center of the heart the switch / intersection and thus a derailment of the device.
  • Figs. 4 to 6 show one of the two links and on the right of the measuring carriage arranged guide skids 22 more in detail.
  • the track rollers 24 a slightly larger diameter than the guide rollers and thus have the side of the guide brackets 25th projected leadership roles, thus ensuring that the Guide rollers do not touch the inside of the rails, if those on the front and track rollers stored in the corner areas of the measuring truck all at roll off the insides of the railheads.
  • This ensures that that the guide rollers start only at the rail inside, if with the gauge a gap or interruption of a rail in the area of a Soft or crossing is run over, but otherwise sufficiently far from the Rail are spaced and thus not distort the measurement result can.
  • the Guide bracket provides guide rollers, which are on the insides of the rails can start, but the lateral support of the measuring carriage by the Guide bracket can also by a runner-like design of the guide bracket be achieved, which then sliding in the rail longitudinal direction of the Inside the respective rail or the rail section along move.
