    The invention relates to a rail-mounted drive device, in particular for a maintenance device, which can be moved along a rail in a direction of movement, with a drive unit, wherein the drive unit has at least one impeller which is drivable via at least one preferably electric drive.
    In many areas of technology large-area surfaces, such as steel, have to be examined and processed. In particular, hulls at regular intervals must be protected against corrosion, this old paint removed and new must be applied. Maintenance devices are used for this task, as described for example in EP 2 651 754 B1 of the Applicant. These
    Maintenance equipment is usually moved on rails along these hulls in the docks where the ships are inspected and overhauled. However, since the hulls have different shapes and lengths, these rails are usually laid freely on the ground of the dock system, in order to be able to be easily removed after completion of the maintenance work. A fixation of the rail, for example by means of screw connections on the ground here is usually not.
    The moving on rails maintenance devices usually have a high weight, Furthermore, they have due to their mostly crane-like structure during maintenance, a constantly shifting towards the rail, which is usually located at a great distance from the ground. However, this causes a large moment of force on the freely laid rail, so there is always the risk of displacement or lifting of the rail. This leads in the further consequence to an instability of the maintenance device, in particular if it is moved along the rail.
    It is therefore an object of the invention to provide a rail-mounted drive device, which allows a repeatable and controlled moving a load, such as a maintenance device along a particular free-laid rail.
    This object is achieved by a rail-mounted drive device of the type mentioned in that at least one Anpresseinheit is provided which is in communication with the drive unit, wherein the at least one Anpresseinheit has at least one loading roller which is pressed against at least one spring element to the rail and / or a fixing device is arranged on the driving unit, wherein a fixing roller is provided, which cooperates with the rail.
    The rail-bound drive device according to the invention is adapted to increase the friction between a non-positively anchored rail and its ground when driving with a heavy load, in particular a Instandahltungsvorrichtung.
    The pressing unit according to the invention has the task to press the rail section before and after the drive unit (seen in the direction of movement) on the ground and to prevent lifting or moving the rail. The at least one spring element in this case presses the load roller onto the rail surface, which runs parallel to the ground. Thus, the pressing unit acts vertically on the rail to ensure the required stability of the rail in the immediate vicinity of the rail-mounted drive device.
    On the drive unit, a fixing device is additionally or alternatively arranged, wherein a fixing roller is provided, which cooperates with the rail for directional fixing of the rail-bound drive device according to the invention. This fixing device acts essentially in a plane parallel to the ground and is in particular in contact with a rail flank. A significant advantage of the fixing device according to the invention is that it prevents a twisting or twisting of the rail due to high shear forces by the load arranged on the rail-bound drive device according to the invention.
    In order to stabilize the position of the pressing unit on the rail, it is provided in a preferred embodiment of the invention that the at least one pressing unit is in contact with the rail via at least one, preferably two guide rollers. These guide rollers are arranged in a plane parallel to the ground and are in frictional contact with the edge of the rail.
    The at least one pressing unit is preferably in articulated connection with the drive unit. When the rail-bound driving device according to the invention is moved along the rail, the pressing unit is arranged either in front of the rail-bound drive device or after it, depending on the direction of movement. Since the laid on the ground rail is usually not straight, but for example, the ship contours following, allows the articulated connection between the drive unit and Anpresseinheit a flexible method of the device according to the invention along a rail with a curved course.
    This movement of the rail-mounted drive device according to the invention on the rail is further improved in a further embodiment of the invention, when the at least one pressing unit is connected to the drive unit via a pivot arm with one, preferably two pivot axes.
    Controlled and secure movement of the load applied to the rail-mounted drive device is further improved in that in a preferred embodiment of the invention the drive unit is additionally in contact with the rail via at least one, preferably two guide rollers, the axis of rotation being at least one, preferably two Guide rollers is aligned substantially normal to the axis of rotation of the impeller of the drive unit. Thus, the impeller of the drive unit is in frictional contact with the rail surface, while the at least one guide roller of the drive unit is in contact with a rail flank.
    The operation of the fixing device according to the invention is further improved if it has at least one, preferably two pivotable stabilizing rollers, which cooperate with the rail.
    In this case, it is particularly preferably provided that the at least one, preferably two pivotable stabilizing rollers can be pressed against the rail via an adjusting device, preferably via at least one hydraulic cylinder. Depending on the direction of movement, that stabilizing roller which precedes the fixing roller is pressed against the rail flank in order to improve the stability of the rail-bound drive device according to the invention on the rail.
    The rail-bound drive device according to the invention is provided for receiving loads and moving them over a rail system. For this purpose, it is provided in a particularly preferred variant that the rail-mounted drive device has a load bearing, preferably a kingpin. This type of load bearing is particularly suitable for the connection of the rail-mounted drive device according to the invention with a crane-like maintenance device, because a kingpin provides an additional rotation axis that allows rotation of the maintenance device with respect to the rail-mounted drive device according to the invention. Thus, for example, the maintenance device can be optimally aligned with the surface to be processed, for example a ship's hull.
    The rail-mounted drive device according to the invention has proved to be particularly suitable for use with maintenance devices, because it is a flexible moving of particular automated
    Maintenance devices for processing large, substantially vertical surfaces, such as ship hulls allowed along freiverlegter rails.
    The invention is explained in more detail below with reference to non-limiting exemplary embodiments with associated figures. Show in it
    FIG. 1 shows a perspective view of the rail-bound drive device according to the invention,
    FIG. 2 shows a sectional view of the rail-bound drive device from FIG. 1,
    FIG. 3 shows a sectional view of the pressing unit from FIGS. 1 and 2,
    FIG. 4 shows a second embodiment of the drive unit of the rail-bound drive device in a first perspective view,
    Figure 5 shows the drive unit of Figure 4 in a second perspective view and
    6, the drive unit of Figure 4 arranged in a third perspective view of a rail.
    FIG. 1 shows the rail-bound drive device 100 according to the invention in a perspective view. Here, the rail-bound drive device 100 along a rail 10 in two directions of movement Al, A2 is movable. For this purpose, a drive unit 200 is provided with a drive 210, wherein this drive 210 is formed for example as an electric drive in the form of an electric motor.
    For receiving a load, for example a maintenance device, a connection element 220, which is designed as a kingpin in the present embodiment of the invention, is arranged on the drive unit 200.
    The sectional view of the rail-bound drive device 100 shown in FIG. 2 shows an impeller 230 arranged in the drive unit 200, which is in frictional contact with the rail surface 11 (FIG. 1) and causes the movement of the rail-bound drive device 100 along the rail 10 via the drive 210 , Since the impeller 230 is moved substantially unguided along the rail surface 11, two guide rollers 240A, 240B are provided, which engage in the rail side 12, whose axes of rotation Dl are substantially normal to a parallel to the axis of rotation D2 of the impeller 230. In this way, the two guide rollers 240A, 240B stabilize the position of the impeller 230 on the rail surface 11.
    In this embodiment of the invention, the rail-bound drive device 100 according to the invention has two contact units 300A, 300B, which are in each case connected to the drive unit 200 via a pivot arm 310. Each drive unit 300A, 300B is in this case connected via two pivot axes S1, S2 to the drive unit 200 via the pivot arm 310. Each drive unit 300A, 300B has a loading roller 320 that is in contact with the rail surface 11. The loading roller 320 is in this case pressed by a spring element 330 on the rail surface 11. The spring element 330 is in this case angordnet such that its longitudinal central axis is normal to the ground, so as to ensure maximum power transmission to the loading roller 320 and subsequently to the rail. This contact pressure ensures that the rail 11 is pressed stable and as immovable as possible on the ground. An improved guidance of the pressing unit 300A, 300B is achieved by the two additional guide rollers 340A, 340B, which in turn are in contact with the rail flank 12.
    If, for example, the rail-bound drive device 100 according to the invention is moved along the rail 10 along the rail 10, which is laid on the ground without additional fixing, such as by means of bolts, the pressing unit 300A provides the loading roller pressed onto the rail 10 via the spring element 330A 320 and the contact pressure acting thereby to ensure that the rail 10 remains in its position on the ground and is not displaced due to the arranged on the rail-mounted drive device 100 load, such as a maintenance device, or even at least partially stands out from the ground. The trailing second traction unit 300B in this direction of movement Al also ensures the stability of the rail 10 in the immediate vicinity of the rail-bound drive device 100.
    Due to the pivotability of the pressing unit 300A, 300B via the pivot axes SI, S2, the movement of the rail-bound drive device 100 according to the invention along curved rails 10 is improved.
    A further embodiment of the invention is shown in FIGS. 4 to 6. Here, the rail-bound drive device 100 according to the invention has an additional fixing device 400, which further improves the running stability of the impeller 230 on the rail 10. The fixing device 400 here consists of a fixing roller 410, which is arranged in a plane normal to the roller 230, and is also adapted to be in frictional contact with the rail edge 12. Via a respective hydraulic cylinder 420A, 420B, which is in articulated connection with a rocking lever 430A, 430B, further stabilizing rollers 440A, 440B can be pressed against the rail flank 12.
    The fixing roller 410 of the fixing device 400 and the guide rollers 230A, 230B of the drive unit 200 are each in a plane (Figure 4) and form a (virtual) triangle, in the center of the roller 230 of the drive unit 200 is arranged parallel to the base line of the triangle , The swiveling
    Depending on the direction of movement A1, A2, stabilizing rollers 440A, 440B of the fixing device 400 are pressed against the rail flank 12 in such a way that in each case the leading stabilizing rollers 440A, 440B are in frictional contact with the rail 10 (FIG. 6).
    It is understood that the present invention is not limited to the two embodiments mentioned above. In particular, the arrangement of the various guide rollers on the rail can be different, in particular it can also be provided that the guide rollers and / or wheel and / or loading roller and / or stabilizing rollers engage in special rail profiles. It can also be provided that the rail-bound drive device according to the invention can be moved on a rail track with more than one rail.
