Definitions

  • the invention relates to a guideway rail according to the preamble of claim 1.
  • a guideway rail has obviously been used in advance by the company AEG-Magnetbahn GmbH in the local transport system magnetic railway in Berlin.
  • the obviously pre-used mass transit system magnetic railway primarily uses elevated guideways, which are composed of individual prefabricated guideway elements. These guideway elements are designed as single-field girders or multi-field girders.
  • the vehicles of this local transport system drive safely against derailment, based on the following functional principle: permanent magnets, which are attached to height-adjustable magnetic carrier strips on both longitudinal sides of a rectangular chassis frame, largely transfer the vehicle weight as a surface load via the guideway rails to the supporting structure of the guideway .
  • a residual load of the vehicle weight is transferred via guide and 5 spacer rollers, which run on the guideway rails.
  • the distance or air gap between the surfaces of the perma demagnetize the chassis and the guideway rails or the surfaces of the long stator attached to the guideway rail is regulated depending on the respective vehicle weight Q (static and dynamic loads).
  • the vehicle is driven (linear motor drive) in the interaction of the permanent magnets of the chassis with the electric traveling field of the long stator on the track side.
  • the route elements consist of two mutually parallel route supports 21 which are connected to one another via cross connectors 12.
  • the cross connectors 12 are
  • the track rails 13 are fastened on both sides in the longitudinal direction on the track supports.
  • the guideway rails 13 form a functional component of the guideway and are used for
  • the guideway is designed as a complete welded construction, in which an upper chord 131 is welded at right angles to the ends of each guideway beam 11, on the end face of which a specially designed
  • N wound and fixed support and guide angle rail 132 is welded. For reasons of support and drive function, driving comfort and wear of the guide and
  • Spacer rollers must be high on the structure
  • the top chords 131 are burned out of steel plates with high accuracy.
  • the angle rails 132 are relatively thin and therefore flexible, so that they give way at their ends under the vehicle load, which leads to comfort-reducing impacts and impairs the service life of the guide and spacer rollers.
  • the object of the invention is to provide a guideway rail of the type mentioned at the outset which, despite high tolerance requirements for the supporting structure, is simpler and cheaper to produce and, moreover, with comparable weight, in particular in the area of the rail joints, has less elastic deformations due to the vehicle load.
  • the invention is based on the consideration, in view of a rational industrial prefabrication of the complete guideway rails with the components top chord, side guide profile and long stator, of providing a guideway construction which allows a manufacturing transition from the usually relatively coarse supporting structure to a precise construction unit.
  • the invention dispenses with a complex, technically problematic special angle rail and instead uses the one that already exists Upper chord of the guideway rail, which is supplemented by a side guide profile attached to the underside of the upper chord as a vertical running rail.
  • the long stator is preferably attached to the underside of the upper chord against the previously welded connection with the aid of a screw connection.
  • the screw-on long stator has considerable advantages, above all for the sake of a better repair and maintenance option for the operation of a local transport system.
  • the entire guideway element need not be replaced. If necessary, it is also possible to dispense with the encapsulation of the long stator, which is required in the conventional welded long stator fastening in order to avoid crevice corrosion.
  • the sufficient strength of the top chord used as the guideway rail allows a simple, form-fitting connection to be made at the joints with the help of sliding bolts which are inserted into the respective top of the abutting top chords, which means that the ends of the guideway rails are also of the same height and therefore free of bumps Ensures transition.
  • the guideway rails which are preferably fastened as deeply as possible in the guideway girder, result in high stiffening of the guideway construction, which in turn results in a reduction in driving and drive noise due to reduced vibration.
  • the design with a low-lying track profile brings considerable advantages for the implementation of a simple, low-cost switch, which, for compatibility with the existing local transport system, may have a drive-passive switch center piece (heart) that carries the vehicle via magnetic forces. is equipped.
  • This switch consisting of two constructionally connected track rails middle piece is mounted around a fulcrum or displacement point.
  • the switch center piece is set with a conventional switch drive according to the desired direction of travel.
  • the reduction in the route height due to the low-lying route profile leads to considerable material savings, in particular in the case of embedded route sections in tunnels or on bridges.
  • FIG. 2 shows a cross section through a low-lying travel path profile of a magnetic rail transport system
  • FIG. 3 shows a cross section through one of the two guideway rails of the guideway profile according to FIG. 2 according to the invention
  • FIG. 4 shows a cross section through the fastening of the guideway rail according to FIG. 3 to the supporting structure of the guideway.
  • the guideway profile shown there has two mutually parallel guideway supports 21 made of a double-T profile, the lower, inner foot of which is transformed into a box profile 24.
  • Each box section serves as a support for an inventive guideway rail 23 which is connected to the relevant guideway support 21 or its box-shaped section 24.
  • each guideway rail 23 consists of an upper belt 31, at the free end of which projects inwardly into the guideway profile, an upper running surface 311 and a lower running surface 312 for the guide and spacing rollers of the chassis, not shown, of a magnetic levitation vehicle described at the beginning form.
  • a lateral guide profile is preferably attached at a right angle, the surface of which forms the running surface 321 for tracking the chassis with vertical rollers within the magnetic track path.
  • the upper chord 31 consists of at least 30 mm thick, rectangular steel profile of approximately 500 to 600 mm in width and a length adapted to the respective length of the individual structural elements.
  • the upper chord 31 can be straight in its longitudinal direction or can be curved accordingly for horizontal curves. In the transition sections of the route to line gradients or line gradients, the top chord is also concave or convex about the transverse axis.
  • the upper belt 31 is connected to the longitudinal beams 21 of the supporting structure by a welded connection or, as shown in FIG. 4, by a special screw connection.
  • the height of the guideway rail 23 is selected so that a minimum distance from cross connectors 22 (FIG. 2) between the longitudinal beams 21 is maintained.
  • the 5 treads 311 and 312 formed by the upper flange 31 at its free ends and the tread 321 formed by the inner surface of the side guide profile 32 can be reworked in the assembled state to reduce the ripple.
  • the ends of abutting upper chords 31 can be provided with form-fitting connecting elements 0, in particular sliding bolts, which are slidably mounted in the associated longitudinal bores in the end faces of the adjacent upper chords 31.
  • the (19 Installations ⁇ profile 32 for tracking the magnetic levitation vehicles by means of the horizontal rollers of the chassis also has, as 5 Fig. 3, has a rectangular cross-section and is preferably welded at a right angle to the underside of the upper belt 31.
  • a long stator 33 is fastened to the underside of the upper chord 31 between the longitudinal beams 21 of the guideway and the side or guide profile 32 of the associated guideway rail 23, in particular screwed with the aid of angled rails 25 according to FIG. 3.
  • the long stator 33 consists of bundles of laminations bundled in the longitudinal direction, the individual laminations 5 of which are insulated and which are coated as a whole laminated core with an elastic insulating material.
  • the downward facing surface of each long stator 33 must be aligned with high accuracy parallel to the upper running surface 311 of the upper chord 31, so that a uniform air gap between the Q long stator and the permanent magnets of the chassis of the magnetic levitation vehicle, not shown, leading parallel thereto is ensured .
  • the fastening construction illustrated in FIG. 4 between the guideway rail 23 and the concrete guideway girder 21 is preferably suitable.
  • a metallic anchor plate is on a horizontal bracket (which can be part of the box section 24 according to FIG. 2) of the concrete guideway girder 21 41 firmly connected, for example cast in.
  • the anchor plate 41 has a dome-shaped curve on its free upper side and has a length of approximately 150 to 200 mm, for example.
  • the flange-shaped areas on both sides of the dome-shaped curve are welded with fastening bolts 45 which project vertically upwards.
  • An adjustment cradle 43 is placed on the anchor plate 41 and has a dome-shaped depression which corresponds to the dome-shaped rounding of the anchor plate.
  • the cradle 43 has corresponding through bores for the passage of the bolts 45.
  • the adjustment cradle 43 can be inclined on both sides with respect to the anchor plate or the track support 21 due to the dome-shaped mounting on the anchor plate 41, as a result of which deviations from the horizontal can be compensated by the track support 21. By using different thicknesses, the cradle 43 also allows height adjustment of dimensional inaccuracies.

Abstract

Les forces de support et d'entraînement pour des véhicules à lévitation magnétique sont produites par un stator longitudinal sur le rail et des aimants permanents sur le véhicule. Le stator longitudinal (33) est fixé à la face inférieure d'un rail qui possède également deux surfaces de roulement horizontales opposées (311, 312) destinées à des paires de rouleaux d'écartement sur le véhicule et une surface de roulement verticale (321) destinée à des rouleaux de guidage latéral sur le véhicule. Pour permettre l'obtenion d'un rail simple et peu onéreux à fabriquer, les surfaces de roulement horizontales sont formées par la section terminale du rebord supérieur (31) du rail et la surface de roulement verticale est formée par un profilé de guidage latéral fixé à la face inférieure du rebord supérieur.
