Track clearer having aerodynamic guide plates

Abstract

A device for removing obstacles from a travel path of a vehicle includes clearing blades being mutually aligned in the form of a wedge and each having a wedge tip end facing the other clearing blade and a free end facing away from the wedge tip end. A fastening device or fastener fastens the device to the vehicle and a device for reducing a pileup generated by the clearing blades reduces pressure fluctuations at the vehicle tip without the need for providing the clearing blades with passages, apertures, or the like. The device for reducing the pileup has at least one vertical guide plate disposed in the vicinity or region of the free end of a clearing blade so that an air stream generated by the clearing blade flows past the vertical guide plate.

(2) FIG. 1 has an exemplary embodiment of the inventive device and the inventive rail vehicle in a perspective representation,

(3) FIG. 2 has a further exemplary embodiment of the inventive device and the inventive rail vehicle,

(4) FIG. 3 has a further exemplary embodiment of the inventive device and the inventive rail vehicle,

(5) FIG. 4 has a further exemplary embodiment of the inventive rail vehicle and the inventive device and

(6) FIG. 5 has a further exemplary embodiment of the inventive rail vehicle and the inventive device.

DESCRIPTION OF THE INVENTION

(7) FIG. 1 shows a first exemplary embodiment of the inventive device 1, which is provided for removing obstacles from a travel path of a locomotive 2 as a rail vehicle. To this end, the device 1 is fastened to the locomotive 2 by a mount (not shown in more detail). The device 1 has two clearing blades 3 and 4 which are aligned in the form of a wedge with respect to each other, which each have a wedge tip end 5 and 6 which face one another. Moreover, each clearing blade 3, 4 has a free end 7 or 8, which faces away from the respective wedge tip end 5, 6.

(8) The clearing blades 3 and 4 extend both in the direction of travel, which is referred to here below as longitudinal direction, and also in the transverse direction, wherein the device 1, which is connected to the locomotive 2 by a fastening device 21, extends in the transverse direction almost across the entire width of the locomotive 2 and thus across almost the entire width of the guideway. A vertical direction, in which in practice the height is plotted, extends at right angles to this longitudinal and transverse direction which runs in parallel to the travel path, which is also referred to here as horizontal plane. In the region of the free ends 7 and 8 of each clearing blade 3 or 4, a vertical guide plate 12 or 13 is arranged in each case as a means for reducing the pileup. Each vertical guide plate 12 or 13 is connected to the respectively assigned clearing blade 3 or 4 by way of a horizontal guide plate 14 or 15. Each vertical guide plate 12, 13 here has a section with a surface 16, which extends in the vertical direction, in other words at right angles upwards in respect of the horizontal. Here the intended longitudinal axes of the surfaces 16 and 17 can have a point of intersection with one another like the clearing blades, as indicated in FIG. 1. Conversely, the longitudinal axes of the surfaces 16 can also be aligned in parallel with the longitudinal direction so that the intended axes do not have a shared point of intersection. The surface 16 of the said section of the vertical guide plate 12, 13 is then aligned in parallel to the side wall 19 of the body of the locomotive 2 which is supported on the chassis 20.

(9) FIG. 2 differs from the exemplary embodiment shown in FIG. 1 in that the vertical guide plates 12 and 13 have an inflow side 17 at their end pointing in the direction of travel, which therefore faces the wedge tip 9, which, in the transverse direction, is therefore curved toward the other clearing blade in each case. The aerodynamics of the device 1 or of the rail vehicle 2 are improved still further in this way. Moreover, design aspects can be taken into account.

(10) FIG. 3 shows a further exemplary embodiment of the inventive device 1, which differs from the exemplary embodiment shown in FIG. 1 in that the horizontal guide plates 14 and 15 are not connected centrally with the vertical guide plate 12 or 13, for instance welded, but are instead molded to the respective vertical guide plate. Here the respective horizontal guide plate 14, 15 serves to connect the vertical guide plate 12, 13 to the respective clearing blade 3, 4, wherein a curvature 18 results on the top side of the respective vertical guide plate 12 or 13.

(11) FIG. 4 shows a further exemplary embodiment of the inventive device 1, wherein a number of vertical guide plates 12 or 13 are arranged on a clearing blade 3 or 4 in each case. Here the respective vertical guide plate 12, 13 is likewise embodied in one piece with the respective horizontal guide plate 14, 15.

(12) FIG. 5 shows a further exemplary embodiment of the inventive device 7, which differs from the exemplary embodiment shown in FIG. 1 again by the embodiment of the means for reducing the pileup, in other words by the respective vertical guide plate 12 or 13. The respective guide plate 12 or 13 thus here comprises an inflow side 17, which is curved both toward the respective clearing blade 3 or 4 and also in respect of the horizontal, which is defined for instance by the lower edges of the clearing blades 3, 4, in other words is sloped upwards or downwards, so that the displaced air is deflected upwards while the locomotive is traveling.
