Definitions

  • the invention relates to a running rail for monorails with preferably electrically driven trolleys, which can be fastened to supporting structures by means of receiving arrangements and each has an upper and lower rail head with a U-shaped cross section, including a channel open to the other rail head, and a rail web connecting the rail heads, wherein the web of the upper rail head is designed as a running surface for rollers and idlers and flanges of the rail heads on the outside as guide surfaces for guide rollers of the trolleys.
  • a traveling rail which is fixed to a horizontal bracket arm of a suspended on the supporting structure bracket means receiving arrangements, each of Block parts of a clamping plate and counter plates exist.
  • the block parts are formed on both sides of the bracket arm at its free end and protrude into the essentially omega-shaped space defined by the two rail heads and the rail web for the form-fitting support of the free flanges of the rail heads up to a stop which, from one of the free ones .Flanges on the outside and connecting the two block parts connecting clamping plate is formed.
  • two counter plates are inserted on both sides of the bracket arm, which rest against the free flanges on the channel side and are screwed to the outer clamping plate.
  • Another disadvantage is that very tight tolerances in the manufacture of the running rail and the block parts as well as the holes for the fastening screws have to be observed, since otherwise no positive support of the free flanges of the running rail on the block parts or screwing of the counter plates and the block parts is possible is.
  • each receiving arrangement has at least one receiving element for each rail head, which can be arranged in the respective channel and brought to the web and / or the flanges for play-free contact.
  • the internal dimensions of the channels are larger than the dimensions of the receiving elements, so that the latter can be easily and quickly arranged within the former. This can be done, for example, by inserting the receiving elements fastened to the receiving arrangement from the front side of the running rail or from rail sections into the channels and by subsequently shifting in the longitudinal direction of the running rail to the desired pick-up point. Only after the desired receiving point has been reached is each receiving element brought into the vertical and / or horizontal direction for play-free contact with the respective rail head, as a result of which the rail is reliably fastened to the receiving arrangement and thus to the supporting structure.
  • a running rail is created which can be attached to the supporting structure in a simple, quick and reliable manner at any point along its length.
  • Another advantage is that the production of the receiving elements and / or the channels can be carried out with greater manufacturing tolerances than in the prior art.
  • the receiving arrangement preferably has a U-shaped receiving head that can be fastened to the supporting structure and has an opening that extends normal to the plane of the rail web on flanges on the free ends of the receiving elements can be attached.
  • the omega-shaped space of the running rail can be kept free for accommodating supply and control devices which no longer find space on the other side of the running rail.
  • the receiving arrangement has an essentially U-shaped retaining bracket, one bracket arm of which can be fastened to the supporting structure and the other bracket arm of which the receiving elements or the receiving head can be fastened.
  • the receiving flanges and the web part of the receiving head are preferably detachably attached to one another or detachably on the holding bracket. This makes it possible to exchange mounting flanges or mounting heads to adapt to different load cases, so that, for example, multiple mounting elements with larger or smaller mutual distances or a single mounting element with greater or smaller length measured in the longitudinal direction of the rail can be arranged within each channel.
  • the receiving element assigned to the lower and / or upper rail head is advantageously detachably fastened to the receiving head or the holding bracket.
  • the receiving element arranged in the channel of the lower and / or upper rail head can be braced with the web of the respective rail head. This can be done, for example, by means of an adjustable threaded bolt happen, which connects the receiving element and the receiving head to each other and presses the former with support on the latter against the web.
  • the wedge it is expedient to design the wedge to protrude out of the channel with the point of its smallest height dimension.
  • the wedge can then preferably be designed as a receiving element.
  • the wedge or the receiving element for bearing against the flanges of the respective rail head can be spreadable.
  • the wedge or receiving element can have, in a known manner, through openings with or without cone bushings and expansion screws which can be screwed into them.
  • the receiving element can consist of plastic material with high damping properties with sufficient strength. This is particularly beneficial for improving sound insulation.
  • the transition from the flanges of the rail heads to the rail web connecting them can be designed as a slope that moves away from the plane of the free flanges of the rail heads with increasing approach to the rail web. This makes it possible to record Form elements in the area of the transition from the flanges to the rail web with a contour adapted to the slope, so that the contact surface of the receiving elements on the rail is enlarged.
  • the adaptability of the system created hitherto can be increased further in that the flanges arranged on the same side of the rail heads and the rail web connecting them lie in one plane.
  • Such an arrangement can be developed for very high loads by symmetrical formation of the running rail to the rail web.
  • the outer surfaces of the receiving elements or wedges assigned to the flanges of the rail heads are preferably roughened.
  • this can take the form of knurling.
  • the flanges of the rail heads preferably consist of a material with a lower hardness than the receiving elements or the wedges.
  • Figure 1 shows a receiving arrangement of a rail 3 of a monorail with electrically driven trolleys, not shown here, with their cbe Ren end is attached to a profile beam 1 of a support structure, not shown, and receives the running rail 3 with its lower end.
  • the running rail 3 consists of butt-assembled rail sections, each of which has an upper rail head 4, a lower rail head 5 and a vertical rail web 6 connecting both.
  • Both rail heads 4, 5 are each formed as a U-profile with a horizontal web 7 and two vertically aligned, mutually parallel flanges and arranged in such a way that the channels 8 enclosed by them are open to the other channel.
  • the sight web 6 connects the flanges 9 shown on the right-hand side of FIG. 1.
  • the free flanges parallel to this are provided with the reference number 10.
  • the flanges 9 have a larger thickness dimension than the flanges 10 and than the rail web 6.
  • the latter is arranged approximately in the vertical center plane of the flanges 9 and connected to them by conical transitions 11.
  • the trapezoidal fin 12 thus formed on the side of the running rail 3 facing away from the channels 8 is provided for receiving busbars 13 for the electrically driven running gears.
  • an essentially omega-shaped space 14 is defined by both rail heads 4, 5 and the rail web 6, the channels 8 being components of this space.
  • the channel-side bevels of the conical transitions 11 are provided with the reference number 15.
  • the surface of the web 7 of the upper Schienenkcpfes 4 serves as a tread 16 for rollers and idlers of the trolleys.
  • the outer sides 17 of the flanges 9 and / or 10 of one or both rail heads 4, 5 serve as Guide surfaces for guide rollers of the trolleys.
  • the receiving arrangement 2 comprises a U-shaped retaining bracket 18 with a vertical bracket web 19, a lower horizontal bracket arm 20 and an upper bracket arm 21 parallel thereto, the upper side of which is expanded to form a horizontally oriented plate 22.
  • Connecting elements in the form of cap screws 23 establish the connection between the plate 22 and a counter plate 24 parallel thereto, which in turn are fastened to the two halves of a lower horizontal flange 26 of the profile beam 1 with fastening means 25 in the form of screwed clamping claws.
  • the bracket 18 has a double-T cross-section.
  • the receiving arrangement 2 further comprises a U-shaped receiving head 27 and receiving elements to be described.
  • the holding head 27 consists of a vertical web part 28 and a lower and a lower holding flange 29 or 30.
  • the vertical web part 28 is welded to the free end of the bracket arm 20.
  • Both receiving flanges 29, 30 extend in the horizontal direction into the omega-shaped space 14 of the running rail 3 and end at a short distance from the rail web 6 near the conical transitions 11. In their corner regions, the receiving flanges 29, 30 have the receiving elements, which in the channels 8 of both rail heads 4, 5 engage.
  • FIG. 3 shows an enlarged sectional view of the design of the receiving elements and their arrangement in the channels 8 of the running rail.
  • this travel rail has two flanges 9, the outer sides 17 of which lie in one plane with the side of the rail web 6 that connects them to the receiving head 27.
  • This rail which is provided with the reference numeral 33, is received on the receiving head 27 with the expandable receiving elements 32 shown in FIG. 2.
  • These each have a cross section of a truncated pyramid 34 with a rectangular base area with a base surface and a cuboid lengthening extending the latter Section 35 on.
  • the height dimension of the receiving element 32 is chosen such that it extends from the web 7 of the respective rail head 4, 5 to the point which, starting from the rail web 6, represents the beginning of the slope 15 of the conical transition 11.
  • the height of the cuboid section 35 corresponds to the vertical dimension of the flange 9, 10.
  • the side surfaces of the truncated pyramid 34 are of the same length as the bevel 15 and fit snugly against it.
  • Each receiving element 32 is expanded with a vertical slot, a bore 36, Mistake.
  • a self-locking conical bushing 37 is arranged in the bore 36 in the region of the cuboid section 35.
  • An expansion screw 38 with a cylindrical thread is screwed into the bore 36 and the conical bushing 37, so that the side walls of the cuboid section 35 rest non-positively on the inside of the flanges 9, 10.
  • the expansion screw 38 passes through the bores 32 in the respective receiving flange 29, 30 and thus simultaneously represents the already mentioned fastening element for the receiving element 32 on the receiving flanges 29, 30.
  • the receiving elements 32 are fastened to the upper receiving flange 30 of the receiving head 27 by means of the expansion screws 38, which, however, are screwed into the internally threaded holes 36 only to such an extent that the receiving element does not expand. It is advantageous here to also provide the bores 31 with an internal thread, so that the receiving elements 32 are prevented from evading when inserted into the channels 8.
  • the lower mounting flange 29 is free.
  • the corresponding receiving elements 32 are already inserted in the channel 8 of the lower rail head 5. Then the rail 3, 33 with its upper rail head 4 or the associated channel 8 is placed on the mounting elements 32 fastened to the upper mounting flange 30 and pressed down until it abuts the web 7.
  • the receiving elements 32 are moved in the channel 8 of the lower rail head 5 until their conical bushings 37 are aligned with the bores 31 in the lower mounting flange 29.
  • the spread screw 38 through these bores 31 into the bores 36 and the conical bushings 37 until they stop.
  • the expansion screws 38 which are partially robbed into the receiving elements 32 on the upper receiving flange 30, are also screwed in as far as possible.
  • the cuboid sections 35 are spread apart and for frictional engagement with the respective flanges 9, 10. brought both rail heads 4.5.
  • the side surfaces of the truncated pyramid 34 form-fit the slope 15.
  • the spread receiving elements 32 used in this way can transmit high forces, in particular those which occur in the longitudinal direction of the running rail.
  • the conical bushing 37 can be omitted and, instead of the expanding screw 38 with a cylindrical thread, one with a conical thread can be used. It is easy to see that instead of the expandable receiving elements, those that cannot be expanded can also be used.
  • both types of receiving elements it is advantageous to attach the expandable elements to the upper receiving flange. It is also conceivable to use only one or three or more such elements instead of two receiving elements per receiving flange. For this purpose, mounting flanges or mounting heads of different lengths and with a different number of holes can be used.
  • a running rail 39 is fastened by means of receiving elements 40.
  • These receiving elements 40 correspond to the above-mentioned receiving elements 32 — the same parts are designated by the same reference numerals — but are designed to be cuboidal throughout over their entire height.
  • rail 39 is formed symmetrically to its rail web 6 and has an upper rail head 41 and a lower rail head 42, both of which each have two free flanges 10 and two channels 8.
  • the remaining components are identified by the same reference numerals as the corresponding elements of the rails 3 and 33.
  • the travel rail 39 is held by means of receiving elements 43, which are formed in one piece with a receiving head 44.
  • the latter is screwed with its web part 28 to the free end of the lower bracket arm 20 of the bracket 18.
  • a receiving head 44 Like the receiving head 27, it is U-shaped, but its horizontal receiving flanges 29, 30 are deflected at right angles in the region of the channels 8 of the travel rail 39 to form vertical extensions, which extensions represent the receiving elements 43.
  • These receiving elements 43 are thus of the same length - in the longitudinal direction of the rail - as the receiving flanges 29, 30 and therefore, in contrast to the above-described receiving elements 32, 40, have a greater length than height.
  • the distance between the channel-side inner surfaces of the webs 7 of the two rail heads 41, 42 is greater than the distance between the bearing surfaces of the receiving elements 43 facing these inner surfaces.
  • the bearing surface 45 assigned to the upper rail head 41 (see FIG. 6) is parallel to the inner surface of the scraper 7.
  • the lower contact surface consists of two inclined surfaces 46 which run obliquely in the longitudinal direction, but which are parallel to the inner surface of the associated web 7 in the transverse direction. Both inclined surfaces 46 are symmetrical to one another, ie their apex is halfway along the length of the receiving head 44. They run in such a way that their distance from the upper bearing surface 45 is greater at the apex than at the two end faces of the receiving head 44.
  • each wedge 47 can be provided with a para on its section which projects in the inserted state on the respective end face of the receiving head 44 lel to the rail web 6 continuous longitudinal slot 48 is provided, in which an only schematically indicated spreading arrangement 49 is arranged.
  • This expansion arrangement essentially consists of a slot extension with an inserted conical bushing and a screw-in expansion screw. 5 and 6, the greatest distance between the bearing surfaces 45 and 46 is greater than the distance between the free ends of the flanges 10, so that the receiving head 44 can only be inserted into the channels 8 from the ends of the respective rail sections . Accordingly, the receiving elements 43 and the wedges 47 have little play in the transverse direction with respect to the respective rail head 41, 42.
  • Fig. 7 shows a receiving head 50 for receiving the running rail 39, which corresponds to the above-described receiving head 44 with the exception that the vertical extension 51 of the lower receiving flange 29 has a lower height than the corresponding vertical extension or the receiving element 43 (Fig. 5) and is also provided with a longitudinal groove 53 embedded in the bearing surface 46.
  • the wedges 52 are formed higher than the wedges 47 described above and are additionally provided on their upper side with a longitudinal rib 54 which engages in the longitudinal groove 53 in a form-fitting manner.
  • the boundary lines of the longitudinal rib 54 are drawn for the sake of clarity at a distance from the boundary lines of the longitudinal groove 53.
  • the height dimensions of the wedges 52 are such that they protrude from the channel 8 over their entire length in the inserted state. This means that the receiving head 50 can be inserted into the channels 8 at any point on the rail 39 from the oemega-shaped space 14 and that the wedges 52 take over the function of the lower receiving elements.
  • the vertical extensions 43, 51 rest against the bevel 15 of the conical transition 11 of the running rail 39.
  • These receiving heads 44 and 50 are particularly suitable for receiving the travel rail in the region of the joint between two adjacent rail sections, since they support the travel rail 39 over a relatively large length with their receiving elements 43 or the wedges 47, 52.
  • switch suspensions, sliding transfers and fixing devices of monorail overhead conveyors can also be designed in the manner according to the invention.
  • the recording head can of course also directly without the intermediary of a bracket on the supporting structure, for. B. a vertical wall bracket. If desired, the receiving elements themselves can also be attached directly to such a wall bracket.
