Definitions

  • the present invention relates to a sliding device for rail vehicles.
  • Rail vehicles including in particular individual cars or wagons of railways, trams, subways or the like rail-bound vehicles, but also from such cars or wagons compiled trains to understand, like other vehicles must be maintained regularly.
  • Such maintenance includes, for example, maintenance of the tires, especially works in the course of which tires are replaced and renewed.
  • a sliding device for rail vehicles which is attached with a wedge-shaped arrangement to a wheel tire of the rail vehicle to be moved, wherein a friction wheel is brought into contact with the peripheral surface of the wheel tire and driven to make the wheel tire itself in rotation.
  • a sliding device which is significantly cheaper compared to the special vehicles described above in the purchase and maintenance, but has the disadvantage that it allows a displacement of the rail vehicle only in one direction. If a rail vehicle has to be moved back and forth in the course of maintenance, then the known sliding device for this purpose is time consuming to implement, which takes valuable maintenance time and is associated with considerable physical work and effort for the maintenance personnel. This is even more negative if the rail vehicle to be serviced has to be moved forwards and backwards repeatedly and alternately.
  • the sliding device according to the invention can be realized comparatively small and compact, can be produced inexpensively and still allows movement, so moving a rail vehicle in different directions, ie back and forth.
  • the sliding device is used as follows, the following description thus also describing a method of moving a rail vehicle within the scope of the invention:
  • the pusher is positioned with the tensioning rack on a rail in the region of a wheel tire of the rail vehicle to be moved so that the wheel tire lies in the clamping gap with a roller bearing section in the rail running direction and another roller bearing section opposite behind the wheel tire.
  • the tensioning means is operated to tension the tensioning frame by drawing the roller bearing portions together until the friction rollers disposed in each of the roller bearing portions abut from both sides of the tensioning space respectively at the peripheral surface of the wheel tire to which the sliding device is mounted with sufficient pressure.
  • the rollers of the sliding device lie on the rail, on which rests the wheel tire on.
  • the direction selection means the direction of rotation of the friction rollers is then specified, to be driven in the latter of the drive motor or the torque transmission means.
  • the drive motor is switched on, so that the torque transmission means transmit the torque generated therewith to the friction rollers.
  • the friction rollers rotate in each case in the same sense of rotation, so that a corresponding acting in the opposite sense of rotation torque on the wheel tire, attacking the friction rollers on the peripheral surface, is transmitted.
  • the wheel tire of the rail vehicle begins to rotate in the direction of rotation of the friction rollers opposite direction, resulting in a method of the rail vehicle. Since the wheel tire is "caught" in the clamping gap, the pusher follows the movement of the rail vehicle, rolling on the rollers over the rail.
  • the direction selection means may be, for example, a switching means for changing the direction of rotation of the drive motor or may also comprise a gearbox with which the transmission of the torque generated by the drive motor in always the same direction of rotation can be set with different directions of rotation.
  • the tensioning frame may have a first portion which comprises the first roller bearing portion and a longitudinally connected thereto, which is fixedly connected to it and extending in the longitudinal direction of the tensioning frame.
  • the sliding device further comprises a second portion, which has the second roller bearing portion and a fixedly arranged on this on the longitudinal support and slidable along the same in the longitudinal direction sliding member.
  • a chain tensioning device may be provided, which has displaceable sprockets and is used to obtain a chain tension of the transmission chain, in particular in an adjustment or adjustment of the opening width of the clamping gap.
  • These displaceable sprockets may, for example, be spring loaded in a tensioning direction of the chain. But you can also with appropriate adjusting mechanisms, e.g. Spindle drives or the like., To be designed adjustable.
  • the clamping gap can be open to one side transversely to the longitudinal direction of the clamping frame. This allows a particularly simple placement of the sliding device according to the invention on the rail and positioning with the two roller bearing sections in front of and behind the wheel tire, without requiring a disassembly of the pusher before installation and assembly after positioning the two roller bearing sections would be required.
  • the sliding device can simply be pushed sideways over the wheel tire from one side and positioned on the rail, then the opening width of the clamping gap can be reduced by actuating the tensioning means and the friction rollers can be brought into contact with the circumferential surface of the wheel tire with a selected pressure force become.
  • the one or more roller arms is or are in particular pivotable, so that they can be pivoted to put on and off the slide to or from the wheel to a position in which you do not engage behind the wheel, the retaining rollers not on the front page abut the wheel tire, but can be pivoted to operate in a position in which they engage behind the wheel tire, the stop rollers abut the end face.
  • the drive motor of the sliding device according to the invention may be an electric motor.
  • an electric motor With such an electric motor, the application of sufficient torque for moving such a rail vehicle, even a train formed from several cars, is possible.
  • Such an electric motor can be operated in particular quiet, which is beneficial to occupational safety.
  • the electric motor with advantage in reduction gear downstream, in order to suppress the high speeds of the electric motor and so at the same time to increase the transmittable torque.
  • the sliding device according to the invention behaves particularly stably if, as provided according to a further advantageous development of the invention, at least one respective roller is arranged in the roller bearing sections next to a respective friction roller.
  • These rollers can be mounted on arranged between two side plates axes.
  • These side panels may be formed as part of an open bearing housing, e.g. a cross-sectionally U-shaped bearing housing with a connecting plate at the bottom. They serve for the stability and secure storage of the rollers arranged in the roller bearing sections, wherein between these housings the clamping gap is advantageously designed to be open to one side (see above).
  • a sliding device for rail vehicles is generally designated by the reference numeral 1. It comprises a tensioning frame 2 with roller bearing sections 3 and 4 arranged thereon. In each of the roller bearing sections 3 and 4, a respective friction roller 5 or 6 is arranged. These friction rollers 5, 6 are aligned leaving a clamping gap 7 formed between them with mutually parallel axes of rotation 8, 9 and opposite peripheral surfaces.
  • a longitudinal member 10 the two roller bearing sections 3, 4 are interconnected. In this case, an upwardly and downwardly open housing of the first roller bearing section 3 bounded by two side walls 12, 13 is firmly connected to the longitudinal member 10.
  • a carriage 17 which is slidably mounted on the longitudinal member 10, so that the distance between the two roller bearing sections 3, 4 and thus the Opening width of the clamping gap 7 can be adjusted or adjusted.
  • a stabilizing strut 18 is firmly formed, which is slidably mounted in sliding bushes 19 which are fixedly connected to the longitudinal member 10 in the longitudinal direction of the longitudinal member 10.
  • roller bearing sections 3, 4 two rollers 20 are arranged in each case, sit in the use of the sliding device 1 on a rail on the tread and roll on this, so as to move the sliding device 1 along the rail.
  • An electric drive motor 22 which is coupled to a reduction gear 27 via a toothed belt, which is not shown here and runs on toothed belt pulleys 21, is seated in the first roller bearing section.
  • This drive motor 22 together generates a required for the displacement of a rail vehicle Torque which is transmitted at the output of the reduction gear to a chain drive assembly.
  • various sprockets 24 are arranged, which are part of the chain drive assembly and one of which is driven directly by the combination of drive motor 22 and reduction gear 27, the other are involved on the circulating transmission chain with and the leadership of the transmission chain and the power transmission serve.
  • sprockets 24 are arranged in the region of the second roller bearing section 4 between the local side wall 15 and a boundary wall 25. Finally, in a first end of the longitudinal member 10 remote from the first roller bearing section 3, there are further sprockets 24 which serve to deflect the circulating transmission chains.
  • two sprockets can be seen parallel to each other per axis.
  • a composed of double links power transmission chain 26 (see. Fig. 4 ) around.
  • the torque generated by the drive motor 22 and converted by the reduction gear 27 is transmitted to the friction wheel 5 arranged in the first roller bearing section 3 and the second friction wheel 6 in the second roller bearing section 4 such that both friction wheels 5, 6 rotate in the same direction of rotation.
  • the direction in which the friction wheels rotate, and thus the feed direction for the rail vehicle by specifying the direction of rotation of the drive motor 22 can be selected.
  • a (not shown) remote control is available.
  • a mechanism not shown in detail is further provided, which allows a clamping of the clamping frame 2 to reduce the opening width of the clamping gap 7 and thus pressing the peripheral surfaces of the friction wheels 5 and 6 to a wheel tire of a rail vehicle.
  • retaining rollers 29 each fixed to a pivoting arm 28 are shown, which can rotate freely about the longitudinal axis of the respective pivoting arm 28.
  • the pivot arms can be pivoted between a in Fig. 3 shown position and a position in which you release the clearance between the roller bearing sections 3 and 4.
  • the pivot arms lock the clamping gap 7, and the retaining rollers are then on an end face of a wheel tire, when it is received in the clamping gap and the friction rollers 5, 6 engage on its peripheral surface.
  • the return rollers roll on the front side of the wheel tire and prevent the sliding device 1 is released from the wheel tire and tilts in the direction of the clamping frame 2 of the rail on which it is placed.
  • Fig. 4 is shown enlarged the leadership of the power transmission chain 26 in the region of the first roller bearing section. 3
  • Fig. 5 illustrates how the sliding device 1 is attached to a wheel R of a rail vehicle with already tensioned clamping frame 2.
  • the sliding device 1 can be easily placed from the front side in the figure with open clamping frame 2 on the rails over the tire R, Subsequently, the clamping frame 2 is clamped by means of the clamping means not shown here while reducing the opening width of the clamping gap 7, to, as in the FIG. 5 shown, the friction rollers 5 and 6 both abut with their peripheral surfaces on the circumference of the wheel tire R.
