    The invention relates to a method and a device for grinding rails of a track according to the preamble of claim 1 and claim 7, respectively.
    [02] Such a device is known, for example, from EP 0 427 940 B1, in which a number of grindstones are fastened one behind the other in the rail longitudinal direction on a support. This in turn is height-adjustable connected to a mobile on the track chassis frame and lowered by hydraulic cylinders in a working position. Each grindstone is also associated with a separate plunger which serves to press against the rail or to periodically lift the individual grindstones into a rest position in which the now exposed grinding surface is cleaned by means of a jet of water from the pores of the stone clogging Schieif mud.
    [0001] FR 1 060 027 discloses a similar apparatus which also describes cleaning of the working surface of the whetstones by cold pressurized water, the water at the same time serving to cool the grinding point.
    The object of the present invention is now to provide a method and a device of the aforementioned type, with which an efficient and also inexpensive rail processing is possible.
    [05] This object is achieved with a method and a device of the generic type by the features cited in the characterizing part of claims 1 and 7, respectively.
    [06] A grinding device equipped with these features according to the invention now offers the advantage that contamination of the working surfaces of the grinding stones can be prevented in a very simple way - so that the grinding quality and efficiency are impaired. For this purpose, according to the claimed method, it is only necessary to turn over the grindstones at certain intervals, as a result of which the abrasion is effectively removed from the grindstone by the friction which now takes place in the opposite direction and with only minimal labor and time expenditure. The rotary drive also creates the advantageous possibility of an ergonomically particularly favorable remote operation of the turning operation, which - according to the features disclosed in the further claims - can also be carried out in a particularly efficient manner during the grinding operation without interruption thereof.
    [07] Further advantages of the invention will become apparent from the dependent claims and the drawing description.
    [08] In the following the invention will be described in more detail with reference to an embodiment shown in the drawing. FIG. 1 shows a schematic side view of a rail grinding machine equipped with a device according to the invention, and FIG. 2 shows an enlarged view of the device.
    A machine 1 shown in Fig. 1 is used for grinding rails 2 of a track 3 and is movable on this basis of egg by rail bogies 4 in egg ner indicated by an arrow 5 working direction. The machine 1 is with driving or working cabins 6, a traction drive 7 and a
    Power source 8 to supply the various (to be described) drives equipped.
    In the area below a machine frame 9, two grinding units 10 arranged in succession in machine longitudinal or working direction 5 are provided between the rail carriages 4 for grinding the rails 2, which will also be described in more detail below with reference to FIG.
    [12] Each grinding unit 10 has a frame 11 which extends over the rail 2 to be machined in the machine longitudinal direction and which can be supported on the track 3 via flanged wheels 12 and is height-adjustably connected to the machine frame 9 by means of two hydraulic drives 13. Two further adjusting drives 14 allow a vertical adjustment of the frame 11 relative to the flange wheels 12 and thus relative to a track plane 15 and a rail running surface 16 of the rail second
    On the frame 11 are a number of machine longitudinal direction one behind the other arranged grindstones 17 can be seen, which rest in the (shown here) working position on the rail running surface 16 of the rail 2 and are pulled in a continuous working movement in the working direction 5 on this. Each grindstone 17 has a rotary drive 18 and is designed so that it can be rotated by 180 ° about a vertical axis 19 extending essentially normal to the track plane 15. Furthermore, each grindstone 17 can also be connected to its own height adjustment drive 20, whereby the rotation and height adjustment drive 18 and 20 are expediently arranged coaxially to the vertical axis 19.
    In use, the grinding unit 10 is lowered by means of the hydraulic drives 13 on the rail 2 to be ground. Thereafter, using the adjusting drives 14, the infeed of the grinding stones 17 until they contact the rail running surface 16. If the grindstones 17 are each equipped with their own height adjustment drives 20, the infeed can also be made via these.
    [15] Since the pores of the grindstones 17 are increasingly clogged by the grinding operation and the grinding performance thereby decreases, the grindstones 17 are rotated by 180 ° at certain selectable time intervals. For this purpose, either the entire frame 11 is lifted by means of the adjusting drives 14 relative to the wheel flange wheels 12 and the grinding stones are rotated by means of the rotary drives 18 and then lowered back onto the rail 2. In the case of a second grinding unit 10, in this case, the rail grinding operation can continue without interruption. Alternatively, each equipped with a Höhenverstellantrieb 20 grindstone 17 are also raised and rotated separately, with some of the grindstones 17 remain in the working position, so that the Arbeitsvorfahrt does not have to be interrupted.
    [16] The rotation of the grindstones 17 is expediently carried out by remote control of the rotary drives 18. It would be optional
    It is also possible for the rotation of the grindstones 17 to be triggered automatically when the skid-tening unit 10 stops working.
