Definitions

  • the invention relates to a mounting rail arrangement for monorails, cranes or the like.
  • a self-supporting mounting rail optionally composed of several rail pieces, and associated connecting, suspension and / or fastening elements
  • the mounting rail having an essentially 1-shaped cross-sectional shape with a hollow upper and has a hollow lower belt and the treads for the wheels of the monorail or crane vehicles carrying two belts are connected to one another by a flat web running in the central plane of the belts, the running surfaces being perpendicular to the central plane and lying on both sides of the central plane.
  • a carrier rail In a carrier rail arrangement known from DE-A-25 45 907 in the form of a conveyor track with a cat running on a rail, a carrier rail is used which is described in detail in DE-B-23 42 777 and in which each belt is on its own Top side has a horizontal tread for wheels and vertical guide surfaces for guide rollers of the monorail vehicles on both opposite outer sides.
  • the cavity of each belt is accessible from the outside via a longitudinal slot running outside the tread and the guide surface, the two longitudinal slots of the belts being arranged in the vicinity of the web to which the belts are connected via inclined surfaces.
  • Such a mounting rail is fundamentally only suitable for top chords. They can only be attached by means of brackets which are screwed or otherwise fastened to the web and which are anchored to a ceiling or other structural parts at the other ends.
  • brackets which are screwed or otherwise fastened to the web and which are anchored to a ceiling or other structural parts at the other ends.
  • there are applications in which such a lateral attachment or suspension of the mounting rail is unsuitable because, for example with regard to the running gear, the web should remain free on both sides or should be available for receiving power supply rails, target control elements or the like.
  • a support rail arrangement as described in US Pat. No. 3,155,207, and whose support rail is designed in the form of a solid I-profile rail, is intended for lower belt chassis.
  • the I-profile rail can be hung or supported on its flanges or belts, but holes must be drilled into the flanges or belts at the suspension or support points, which is complex and expensive for assembly.
  • such an I-profile rail which is made of solid material, is very heavy, so that for this reason alone it is out of the question for many applications, such as lighter monorail systems.
  • the object of the invention is therefore to provide a mounting rail arrangement for monorails, cranes or the like. Which is optionally suitable both for use with upper and lower belt trolleys and is characterized by simple suspension or fastening options of the mounting rail with a high load-bearing capacity and low weight .
  • both belts of the mounting rail are formed by tubular hollow bodies which are rectangular in cross section and which bear treads on the side adjacent to the web, that a belt is closed and also on the side facing away from the web Has treads, and that the other belt on its side facing away from the web is provided with a longitudinal slot running symmetrically to the central plane, can be used in the suspension elements for hanging the mounting rail with the top longitudinal slot or fastening elements of the mounting rail with the bottom longitudinal slot.
  • the mounting rail of this mounting rail arrangement is distinguished by a high load-bearing capacity because of the closed cavity of the one belt, which acts like a support tube stiffened by the web.
  • the mounting rail arrangement can be used optionally for upper or lower belt trolleys, while on the other hand the symmetrical longitudinal slot of the slotted belt opposite the web and leading to the outside offers a simple, effective fastening or suspension option for the mounting rail without using brackets or consoles that extend laterally from the web would have to be, but in special cases, where they are desired, can also be attached optionally.
  • the closed belt seen transversely to the median plane, can be narrower than the other belt because its width is only in consideration of the running.
  • the closed belt viewed in the direction of the web, can also be lower than the other belt. It is advantageous if all pairs of outer surfaces running parallel to each other, at least the closed belt, are designed as guide surfaces, and that the belt with the longitudinal slot also has running surfaces on its side facing away from the web, so that the same mounting rail can be used for the most varied of drives can.
  • At least one row of holes extending in the longitudinal direction is formed in the web, which eliminates the time-consuming and cumbersome drilling of holes during the mounting of the mounting rail arrangement and for attachment from the side the web arranged power supply and control devices. It can also be used to screw down brackets or other construction elements.
  • the row (s) of holes can be provided according to the respective requirements, but it is generally expedient if a row of holes is arranged on the longitudinal axis of the mounting rail.
  • connection means can - if the web is provided with at least one row of holes - be formed by hollow rivets inserted into holes in the row of holes, but spot welding of the wall parts is also conceivable.
  • the mounting rail can be cold rolled from sheet metal.
  • Adjacent rail pieces of the mounting rail arrangement can be connected to one another at the abutment points by elongated connecting elements which are inserted into and fastened to the belts, of which the connecting elements provided in the slotted belt are arranged to the side of the slot, so that the belt has a longitudinal groove which opens along the slot is provided, which is not interrupted by the connecting elements.
  • At least one retaining plate can also be arranged which overlaps the slot and is connected to a fastening element which projects through the slot and is fastened to the belt.
  • the holding plate can in turn be screwed to a flat holding part resting on the slotted belt by means of the fastening element.
  • This holding part can be a console or the like. however, it can also be formed by a simple counterplate if the mounting rail is held by the fastening element designed in the manner of a tie rod.
  • the holding plate can be formed in the region of the slot with a ball socket in which a corresponding ball of the fastening element designed as a tie rod is mounted.
  • the holding plate can be screwed to a correspondingly designed counterplate placed on the outside of the belt.
  • a flexurally rigid profiled rail which is at least continuous over a part of the mounting rail length is placed on the slotted belt and is rigidly connected to the belt by means of the fastening elements.
  • This profile rail can advantageously be U-shaped or C-shaped in cross section.
  • holding elements for current collectors, target control elements or the like can be anchored to the row of holes, which can also be latched to the assigned holes in the row of holes.
  • the holding elements can be spring clips, for example, which are suspended at one end in a corresponding hole in the row of holes and at the other end in the slot of the slotted belt under pretension.
  • a slider or driving element for hanging cables or the like is guided in a longitudinally movable manner on the slotted belt, which is arranged in the belt , Has bearing element mounted on both sides of the slot, to which a narrow web projecting through the slot is fastened, to which the hanging cable or the like is fastened.
  • the arrangement can also be such that such a sliding or driving element for hanging cables or the like is guided in a longitudinally movable manner on one of the belts, the sliding or driving element being a bearing element which laterally grips around the belt and is mounted on the running surfaces adjacent to the web having.
  • the new mounting rail arrangement and the mounting rail used can be used universally for both lower and upper belt trolleys, the associated electrical conductor lines of which can be easily attached to the web at any point in an easily accessible manner.
  • the mounting rail can be used with the closed belt pointing downwards or upwards, which results in a large number of possible combinations, particularly in the area of overhead traveling cranes, crane runways and crane bridges, and single or double-girder overhead traveling cranes.
  • brackets can be screwed on for fastening separately routed power supplies (conductor rail or cable trolley track); with a slot at the bottom, the mounting rail can be screwed directly onto brackets or supports as a crane runway rail, while, as already explained, with a slot at the top, it can be hung with ball joint brackets and threaded rods and similar tie rods. It can also be screwed or clamped directly onto an existing building structure.
  • the components of the mounting rail arrangement can also be used for the construction of portal, semi-portal, console and slewing cranes, to mention only a few further possible uses.
  • the lower closed belt 8 is, seen transversely to the central plane 9, narrower than the upper belt 7; it is also, seen in the direction of the web, lower than the upper belt 7.
  • the outer surface 14 opposite and parallel to the treads 12 is also designed as a tread, while in the slotted belt 7 the surfaces 15 running parallel to the treads 11 can also be used as treads, although they are in the Usually serve as mounting and contact surfaces.
  • the mounting rail 3 is made in one piece from sheet metal in the embodiment shown, i. H. made of cold rolled steel.
