Definitions

  • the invention relates to a device for fastening and adjusting the height of a component on a rail vehicle.
  • a component is also understood to mean an assembly or a functional unit that is composed of several individual parts. Examples of such components are, for example, the transmitter coil of a punctiform train control system (PZB). Such a punctiform train control system was formerly referred to as inductive train protection (INDUSI).
  • PZB punctiform train control system
  • INDUSI inductive train protection
  • Other components that can be named as examples are, for example, the brake magnet of a magnetic rail brake, a sanding device, a device for lubricating wheel flanges or a rail clearer.
  • these components In order for them to work properly, these components must be arranged vertically at a defined distance from the tracks or rails.
  • a height-adjustable suspension device for a brake magnet of a magnetic track brake is known.
  • a first vertically arranged clamping plate is attached to the bogie.
  • This clamping plate has horizontally running longitudinal grooves which form a toothing with correspondingly shaped horizontally running ribs of a second clamping plate and result in a form fit.
  • the braking magnet is attached to the second clamping plate.
  • the height of the brake magnet above the rail can be adjusted by inserting the ribs of the second clamping plate into the shaped grooves of the first clamping plate at the desired height.
  • This suspension device allows a height adjustment only in discrete steps, the increments of these steps corresponding to the spacing of the longitudinal grooves in the vertical direction from one another. Thus, an exact height adjustment is not possible.
  • a height-adjustable housing fastened to a rail is known. If necessary, the stationary housing can be adjusted in height by screwing a threaded bolt, which supports the housing, more or less deeply into the horizontal section of a console fixed to the rail.
  • Another disadvantage of this system is that for moving the second clamping plate from one longitudinal groove of the first clamping plate to another longitudinal groove, the second clamping plate and with it the entire brake magnet must be raised or held. Due to the not inconsiderable weight of the brake magnet, this is a very strenuous and accident-prone job. This work must also be carried out by at least two people, since the first person is required to move the second clamping plate and the second person opens the associated clamping screws and then closes them again.
  • a device according to the preamble of claim 1 is known.
  • the object of the invention is to provide a fastening device which avoids the disadvantages of the solutions known from the prior art.
  • a stepless height adjustment should be made possible.
  • the fastening device should be able to be actuated by one person and the risk of accidents should be reduced.
  • the adjusting screw according to the invention which extends in the installed state of the fastening device in the vertical direction, firstly makes it possible to steplessly adjust the height of the clamping plate. As a result, the height of the component above the rails can be adjusted very precisely. Furthermore, the adjustment screw supports the weight of the clamping plate and the component attached to it during the adjustment process. As a result, the height adjustment can be carried out by one person. In addition, the risk of accidents at work when adjusting the height is drastically reduced. In addition, there are considerable economic advantages due to the saved working time.
  • the fastening device according to the invention enables stepless adjustment, it is also possible to fully utilize the limits for height adjustment and thereby reduce the number of adjustments. This also results in a further economic advantage.
  • clamping surfaces are designed as smooth and non-profiled surfaces, which has an advantageous effect on the manufacturing costs. These clamping surfaces are also insensitive to dirt. This means that the height adjustment can also take place without restrictions if the fastening device according to the invention is dirty as a result of the operation of the rail vehicle.
  • the clamping surface comprises a plurality of partial surfaces, that the partial surfaces are arranged at a distance from one another and that a clamping screw is provided on each partial surface.
  • the distance between the force application points of the clamping forces transmitted between the two partial surfaces results in a better and more secure fixing of the clamping plate and the component attached to it.
  • a particularly advantageous embodiment of the device according to the invention provides that at least one through opening for the at least one clamping screw is provided in the clamping surface.
  • This through-opening can be formed, for example, as an elongated hole and thereby enables the height adjustment of the clamping plate on the one hand and a limitation of the height adjustment of the clamping plate on the other hand.
  • the clamping surface has at least two partial surfaces and that the adjusting screw is arranged between the two partial surfaces.
  • the structure of the fastening device according to the invention is essentially symmetrical, so that the clamping plate hangs approximately horizontally on the adjusting screw and is held in this position by the latter, even when the clamping screws are loosened.
  • it is firstly not necessary to align the clamping plate and the component attached to it horizontally during the adjustment process. This is done automatically by the weight of the clamping plate and the component attached to it.
  • Another advantage of this design is that the fastening device remains functional even if a clamping screw fails, since the adjusting screw essentially absorbs the entire weight of the clamping plate and the component attached to it and the second remaining clamping screw takes over the fixing of the clamping plate.
  • two adjusting screws are to be provided, the two adjusting screws being spaced apart from one another in the direction of the clamping surface. In this case it is sufficient to provide a clamping surface between these two adjusting screws. Because the two adjusting screws are spaced apart from one another in the direction of the clamping surface and in the direction of travel of the rail vehicle, it is possible to align the component fastened to the clamping plate exactly horizontally.
  • the front part of the component in the direction of travel is to be raised slightly, this can be done by turning the adjusting screw located at the front in the direction of travel clockwise. The same applies to the rear end of the component in the direction of travel. As a result, a very precise and nevertheless simple alignment of the component in a horizontal orientation can be achieved.
  • the clamping surface is arranged between the adjusting screws. Even then, there is a symmetry in the structure and a redundancy in relation to the failure of an adjusting screw. In this case, the clamping connection acting between the clamping plate and the clamping piece and the remaining adjusting screw take over the fixing and positioning of the clamping plate and the component attached to it relative to the rail vehicle.
  • a particularly simply constructed and easy-to-use embodiment of the invention provides for forming at least one nut thread for the at least one clamping screw in the clamping piece. This allows the clamping connection to be opened and closed by simply turning the clamping screw. Holding a nut is not required. However, it goes without saying that it is also possible to provide a through hole in the clamping piece instead of the nut thread and to provide a nut with a washer or spring washer on the back of the clamping piece.
  • guide means can be provided in a further advantageous embodiment, which interact with corresponding counterparts, such as springs or guide bolts, on the clamping plate.
  • Such linear guides are generally off known in the prior art and are therefore not shown and explained in the drawings. It goes without saying that the linear guides are arranged parallel to the adjustment screws.
  • FIG 1 part of a bogie 1 with a wheel set 3 is shown.
  • the wheel tire of wheel set 3 rolls on a rail 5 .
  • a transmission coil 7 of a system for punctiform train control (INDUSI) attached to the bogie with the aid of a height-adjustable fastening device 9 .
  • INDUSI system for punctiform train control
  • the transmitting coil 7 it is necessary for the transmitting coil 7 to be at a predetermined distance A from the rail 5 in the vertical direction.
  • the transmission coil 7 should run as parallel as possible to the rail 5, ie in a horizontal direction.
  • the distance A between the transmitter coil 7 and track 5 decreases continuously.
  • the transmission coil 7 must be readjusted by being reattached slightly offset upwards. This task is performed by the height-adjustable fastening device according to the invention.
  • the use of the fastening device 9 according to the invention is not limited to the fastening of transmission coils 7 of a punctiform train control.
  • the application is particularly suitable where components or assemblies of the rail vehicle are arranged at a certain, precisely specified height above the rails and have to be readjusted if the wheel tire wears accordingly, such as the devices for sanding and wheel flange lubrication and the magnetic rail brake mentioned at the beginning.
  • the most important assembly parts of the fastening device according to the invention are a clamping piece 11, a clamping plate 13 and an adjusting screw 15. These components are in figure 2 in an isometric and in figure 3 shown individually.
  • the clamping piece 11 comprises a clamping surface 17, which is divided into two partial surfaces 17.1 and 17.2 in the exemplary embodiment shown.
  • a threaded hole 19 is arranged in each of the two partial surfaces 17.1 and 17.2.
  • the two partial surfaces 17.1 and 17.2 are connected to one another by a crossbar 21.
  • the crossbar 21 is part of the clamping piece 11 and can be attached to the bogie 1 of the rail vehicle, for example by welding. Alternatively, it is of course also possible to fasten the clamping piece 11 to the bogie 1 of the rail vehicle in another way, for example by means of screws (not shown) on the bogie 1.
  • a through hole 22 is provided in the crossbeam 21 in the middle between the partial surfaces 17.1 and 17.2.
  • the adjusting screw 15 is inserted through this through hole 22 and screwed into a nut thread 23 of the clamping plate 13 .
  • the clamping plate 13 is designed in such a way that it rests on the partial clamping surfaces 17.1 and 17.2.
  • two elongated holes 25 are cut out, the lateral spacing of which corresponds to the spacing of the threaded bores 19 in the clamping piece 11.
  • the clamping plate 13 can be adjusted with the help of clamping screws 27 (see figure 2 ), which are screwed into the threaded holes 19, are clamped to the clamping piece 11.
  • the adjusting screw 15 is inserted through the through hole 22 of the crossbar 21 of the clamping piece 11 and screwed into the nut thread 23 in the clamping plate 13 .
  • the height of the clamping plate 13 and a component attached to it is adjusted by turning the adjusting screw 15 and can be carried out very easily and by one person. To do this, the clamping screws 27 (see figure 2 ) solved and the clamping between clamping plate 13 and the Clamp 11 lifted. Then, by turning the adjusting screw 15, the height of the clamping plate 13 is adjusted continuously and very sensitively relative to the clamping piece 11.
  • This adjustment can be easily performed by one person since the weight of the clamping plate 13 and the component 13 attached thereto is borne by the adjustment screw 15 during the adjustment process.
  • the clamping screws 27 are tightened, the weight of the clamping plate 13 and the component attached to it is transferred from the clamping connection between the clamping plate 13 and the clamping piece 11 .
  • the symmetrical structure has the advantage, among other things, that even if one of the clamping screws 27 should be lost, the clamping plate 13 is still held securely. In this case, the weight of the clamping plate 13 and the component attached to it would be borne by the adjusting screw 15 and the second clamping screw 27 . The remaining clamping screw 27 also ensures that the clamping plate 13 does not move relative to the clamping piece 11 .
  • the adjusting device according to the invention still has a redundancy against failure.
  • the two clamping screws 27 would hold the clamping plate 13 and the component attached to it.
  • the missing screw or a broken screw will be discovered and the defective screw can be replaced.
  • FIG 4 a side view of the fastening device is shown again.
  • a sleeve 29, which protects the adjusting screw from water and dirt, can be seen clearly, as can the lock nut 30 for fixing the adjusting screw 15.
  • the figure 5 shows a section along line AA figure 4
  • the figure 6 cut along line BB figure 4 indicates.
  • FIG 7 shows an embodiment according to the invention with two adjusting screws 15 in an exploded view.
  • the two adjusting screws 15 are arranged at a distance from one another.
  • a clamping surface 17 is arranged in the middle between the two adjusting screws 15 .
  • the clamping plate 13 is clamped to the clamping piece 11 with the aid of a clamping screw (not shown).
  • a clamping screw not shown.
  • the two adjusting screws 15 reliably prevent the clamping plate 13 from tilting at one end.
