Definitions

  • the invention relates to a travel path limitation for undercarriages, in particular for hoists, according to the preamble of claim 1.
  • a generic guideway limitation for running gear is known, which is supported on a rail with a flange and a web.
  • the travel path limitation consists of two claw-like side elements which are arranged on both sides of the flange in such a way that they can be pressed against the two flange sides in the assembled state.
  • the pressure is applied by means of a clamping device which connects the two side elements to one another at the same time. Screws are used as clamping elements.
  • the side elements In the assembled state, the side elements have two through openings aligned with one another, through which a tension element loaded under tension projects.
  • buffer elements are provided on the side elements.
  • the buffer elements are always on the inside of the flange. This limitation of the travel path is therefore not usable for running gear in which the guide wheels are arranged in front of and behind the running wheels when viewed in the direction of travel.
  • the two clamping pieces are arranged on each side in such a way that their hypotenuse surfaces abut one another, one of the two clamping pieces being able to be pressed against the outside of the flange by means of the wedge effect, using the wedge effect.
  • the vertical positioning of the other (second) clamping piece during the assembly of the travel path limitation enables an elongated hole through which the tensioning element is passed.
  • This solution has a relatively complicated structure by means of two clamping pieces and requires a relatively complex assembly.
  • this type of guideway limitation for flanges with sloping inner sides cannot be used in either arrangement.
  • the application was based on the task of designing an economical travel path limitation for trolleys, in particular for hoists, which is fastened to a flange with two claw-like side elements each having a through-hole via tensioning elements and a tensioning element which is subjected to tension, so that the limitation is both above can also be used below the carrier.
  • each side element in the assembled state parallel to the first aligned through-openings has a further parallel through-opening with which these can be attached to the flange in a second arrangement are by vertical rotation of the side elements by 180 °, and that the clamping elements supporting the side elements are each supported on the flange and on a support element located in a side element. It is thus possible to fasten the travel path limitation in such a way that the buffer element can optionally be arranged above and below the flange.
  • the buffer element On undercarriages with the front and rear seen in the direction of travel the impellers arranged guide wheels, the buffer element is arranged below the flange, so that the buffering takes place in the event of the impact of a chassis on the housing or frame of the chassis.
  • this travel path limitation can also be attached to the upper flange, so that it can also be used for traveling gears that can be moved on the upper flange.
  • the proposed reversibility of the side elements by vertical rotation consequently enables a more universal use.
  • each side element has a U-shaped groove facing inwards in the assembled state, which in the first and second arrangement encompasses a lateral flange end.
  • the mechanical properties of the travel boundary are improved if the groove has a rectangular cross section.
  • the clamping device is arranged directly opposite the flange outer surface.
  • the travel path limitation as a whole thus encompasses the associated flange of the travel rail.
  • the clamping device is structurally simple if it has the threaded spindle, the end of which can be pushed through one of the two through openings formed in the associated side element and connected to the side elements by means of fastening elements.
  • threaded spindle run parallel to the flange outer surface and transversely to the web.
  • the threaded spindle is expediently arranged at a distance from the flange outer surface, since this is the only way to ensure the required stability.
  • the rotatability of the side elements with high mechanical resilience results if the tensioning elements penetrate one of the two groove side walls arranged parallel to one another perpendicularly and extend transversely into the groove.
  • the solution is stable and structurally simple if the groove side walls run parallel to the flange outer surface.
  • the clamping elements are designed as screws that can be locked against the inner flange surface or the outer flange surface.
  • the side elements are simply attached to the threaded spindle using nuts that can be screwed on at the ends.
  • the travel boundary 1 shows a travel boundary 1 which is fastened to a travel rail 2 with upper and lower flanges 2a, 2b and a web 2c.
  • the travel path limitation 1 prevents it from moving beyond a predetermined area of the travel rail.
  • the running gear can run with its rollers on the upper flange 2a or on the inside of the lower flange 2b.
  • the travel path limitation 1 consists of two side elements 3, 4 arranged on both sides of the lower flange 2b, which are firmly connected to one another by means of a clamping device 5.
  • the tensioning elements 6, 7, which are designed as screws, are used, which are pressed against the outer surface 8 of the lower flange 2b and thus conduct the vertically upward forces into the travel rail 2.
  • the roadway buffer element 9 made of rubber (see FIG. 2) is arranged below the flange 2b and absorbs the impulse forces in the event of a chassis impact.
  • the running rollers of the undercarriage roll on the inside of the flange 10 in this embodiment, i. H. the frame or the housing of the hoist abut against the carriageway buffer element 9.
  • Each side element 3, 4 has a U-shaped groove 11, the cross section of which is essentially rectangular, that is to say the groove side walls 11a run approximately parallel to one another. In the assembled state, each groove 11 faces inwards and runs in the longitudinal direction of the travel rail 2.
  • FIG. 1 shows that the claw-like side elements 3, 4 encompass the lateral flange ends.
  • the clamping device 5 directly opposite the flange outer surface 8 consists of a threaded spindle 12, the ends of which are each inserted through a through opening 13 or 14 formed in the associated side elements 3, 4.
  • the ends of the threaded rod 12 are firmly connected to the side elements 3, 4 by means of the fastening elements 15, 16 designed as nuts 15a, 16a.
  • the bottom 17 of the groove 11 is pressed against a flange side surface.
  • the tensioning elements 6, 7 are required for stabilization, which penetrate the lower groove side wall 11a vertically and are stretched against the flange outer surface 8 and extend transversely into the groove 11.
  • an internal thread is formed in the groove side wall 11a.
  • the two inner flange surfaces 10 run parallel to the outer flange surface 8, so that the lower flange 2b with its inner flange surface 10 is pressed flat against the upper groove side wall 11a by the clamping elements 6, 7. 1 further shows that the threaded spindle 12 runs parallel to the flange outer surface 8 and transversely to the web 2c, namely at a distance from the flange outer surface 8.
  • the clamping elements 6, 7 run transversely to the threaded spindle 12,
  • two further parallel through openings 18a, 18b can be seen on the side of the groove 11 opposite the tensioning element. These two through openings 18a, 18b make it possible for the two side elements 3 , 4 to be fixed by vertical rotation by 180 ° in a second arrangement on the flange 2b.
  • the side elements 3, 4 grip the lateral flange ends with their U-shaped groove 11, the grooves 11 facing one another.
  • the clamping elements 6, 7 are each supported on the inner surface 10 of the flange.
  • FIGS. 4 and 5 show the side view and plan view associated with FIG. 3. It can be seen in FIGS. 4 and 5 that the carriageway buffer elements 9 are now arranged inside the rail 2, so that, according to FIG. Are the side elements 3, 4 z. B. made of cast aluminum, it is useful to cast nuts 19 as support elements in the castings, as shown in Fig. 3.
  • the tensioning elements 6, 7 supporting the side elements 3, 4 are therefore each supported on the flange 2b and on a support element 19, the two support elements 19 each being located in a side element 3, 4, either on the opposite side to which the tension element 12 loaded under tension is located or on the same side as the tension element 12 loaded under tension.
