Definitions

  • the present invention concerns a travelway for a track-guided vehicle, in particular, a magnetically levitated railway, said travelway comprising a carrier and with at least one functional component affixed to the carrier for the guidance of the vehicle.
  • attachments are bound to the carrier by means of shape-fit connections.
  • pins are provided, which can be introduced into corresponding blind borings in the carrier or into a plate thereon.
  • the pins and the blind borings are required to provide exact seating in order to make possible a position-perfect location of the attachment. Accordingly, it is necessary, that the blind borings be precisely drilled. Such an operation is especially expensive in the manufacture of said carrier assembly.
  • a friction-based connection is employed.
  • a console plate is fastened on the carrier. Attachments can then be affixed to the console plate by means of three bolts, which penetrate oval, or extended holes. All forces to which the carrier is subjected are to be overcome by the friction of the said closure. Should one of the friction-based connections fail, the possibility cannot be overlooked, that the attachment in the said oval hole of the console plate would be pushed so far, that travel operation on the corresponding carrier could no longer be possible, or at the best, be executed in only a limited manner.
  • the purpose of the present invention is to create a travelway, which assures a secure operation of the track guided vehicle, even in a case, where the actual fastening means for the attachment fail on the carrier.
  • the attachment has a frictionally based connection in its binding to the carrier, and further contains a redundant system, which, in a case of emergency, can be activated into use.
  • the redundance system is so designed or arranged, that it can detect an erroneous condition, and thus, as soon as possible can release corrective measures as quickly as possible, in order to restore the proper behavior of the connection.
  • consoles are placed on the carrier, onto which the said attachment can be fastened.
  • both the frictionally based connection as well as the redundance system can be very easily installed. Necessary machining of the consoles can be carried out either in their position on the carrier, or before the installation thereon.
  • the redundance system comprises at least one bolt, which is affixed to a console or to the carrier, then the bolt boring should be found in a concentric opening of the attachment of greater cross-section.
  • one bolt can also be fastened to the said attachment in an opening of the carrier and/or of the console.
  • the bolt can displace itself within the concentric opening of greater cross-section up to the end of the bolt play distance. Only when the bolt abuts the wall of the opening, can a shape-fit connection of the attachment onto the carrier or console be established.
  • the cross-sections of the bolt and the opening are circular and exhibit a difference in diameter of about 4 mm.
  • the bolt is then allowed, from a concentric starting point, to have a free movement of about 2 mm.
  • the attachment is held by screws on the carrier or on the console, and if the diameter of the penetrating screw boring is clearly greater, especially 3 mm greater than the diameter of the screw, then a second redundance system has been created. If the non-slidable (i.e. frictional) binding, which is made by screws, fails, then the attachment drops to the end of the bolt play. If the bolt play, for example, is 2 mm, and if the screw play would permit 3 mm, then, in this case, the bolt would seize-up in a shape-fit connection and limit the distance through which the attachment can drop.
  • the bolt play for example, is 2 mm, and if the screw play would permit 3 mm, then, in this case, the bolt would seize-up in a shape-fit connection and limit the distance through which the attachment can drop.
  • a vehicle which travels by means of such a dropped position of the attachment, can detect this sinking and issue a signal, that at this position the actual, frictional binding has released itself and the redundance system is in action. On this account, a maintenance program can be subsequently undertaken. However, the travel operation has not been endangered.
  • the contacting surface of the carrier and/or the console, and/or of the attachment has a friction enhancing surface material, especially an appropriate coating.
  • a frictional coating By means of a frictional coating, the machining work of the contacting surfaces is made as simple as possible. Even in the case of a damaging of the surface before the assembly of the attachment, this surface, under some conditions, can be improved without the necessarily impairing the frictional connection. With such a connective arrangement, it is possible that the installation of a bolt can be omitted.
  • the shape-fit, redundant system would, in this case, be created by the screw connection and/or inserts in the fastening surfaces.
  • FIG. 1 a section through a carrier, a console and an attachment
  • FIG. 2 a section through a connection position in the zone of a bolt
  • FIG. 3 a top view on a connection position in the operational state
  • FIG. 4 a top view of a connection position subjected to action of a redundant system
  • FIG. 5 a connection position in section in the zone of the screw connection in the operational state
  • FIG. 6 a section of the connection position in the zone of the screws when subjected to the action of the redundant system.
  • FIG. 1 In FIG. 1 is shown a section through a portion of a concrete carrier 1 , a console 2 placed thereon to which is connected an attachment 3 .
  • the concrete carrier 1 and the console 2 are, normally, firmly bound together.
  • This binding can consist of a screwed connection, similar to that which is employed between the console 2 and the attachment 3 .
  • the invented connection will be described in relation to the binding together of the console 2 and the attachment 3 .
  • Both the console 2 as well as the attachment 3 possess, respectively, a connection surface by means of which the two components are bound together.
  • the connection of console 2 and the attachment 3 is carried out essentially by screws 4 which penetrate through the said connection surfaces of the console 2 and the attachment 3 .
  • This screwed connection By means of this screwed connection, the two connection surfaces are pressed together, thereby causing the frictional connection.
  • This connection suffices, in general, for the acceptance of the forces acting on the attachment 3 and for the transmission of said forces to the console 2 and the carrier 1 .
  • a bolt 5 is placed in the connection zone of the console 2 .
  • the bolt 5 is securely in threaded connection with the console 2 and is contained in an opening 10 of the attachment 3 , which opening 10 is a boring of specified greater diameter than the bolt.
  • this opening 10 possesses, in comparison to bolt 5 , a play in the boring, which, advantageously, is so dimensioned, that even in a case of failure, that is, if the holding force of the screws 4 have failed, a sinking of the attachment 3 can only continue to an extent which does not endanger the travel operation of the vehicle, during its run over the attachment 3 .
  • FIG. 2 In FIG. 2 is shown a detail view in the zone of a bolt 5 .
  • the console 2 possesses a boring, within which the bolt 5 and its shaft 7 is accommodated.
  • the bolt head 8 is inset into the console by a nut 6 .
  • the console 2 or conversely, the attachment 3 can have a projection integrated into the console 2 or the attachment 3 , which projection engages itself within the said opening of the opposite component. It is particularly advantageous, if the bolt head 8 , is visible in its position in the opening 10 of the corresponding component, in order to be able to carry out a visual assessment of the state of the operational-position.
  • the open clearance 10 relative to the bolt head 8 should be an annular opening.
  • the said open clearance counter to the specified operational position, will show a zero opening at one place and the attachment 3 is directly abutting the bolt head 8 .
  • the contact surfaces between the console 2 and the attachment 3 are provided with a coating ( 9 , 9 ′).
  • the said coating has an alkali-zinc-silicate base in the form of a paint-like material which has proved itself to be very advantageous. This coating causes an especially great frictional resistance at a reasonable cost and is simple as to being restored. If such a coating is used, consideration may be given to the omission of the installation of bolt 5 either partially or entirely.
  • FIG. 3 shows a top view of the boring locations of the console 2 and the attachment 3 .
  • the borings for the screws 4 are found in their operational positions in concentric, axial alignment. The same is true for the borings for the bolts 5 , where again a concentric, axial alignment can be seen.
  • the bolt head 8 possesses a radius R 1 .
  • the opening 10 in which the bolt head 8 is seated, has a radius of R 2 and radius R 2 is greater than radius R 1 .
  • a radius difference of 2 mm has shown itself as being advantageous, since with this dimensioning the travel operation of the vehicle cannot be endangered, as the attachment 3 drops down onto the bolt head.
  • FIG. 4 the said boring clearance is shown when attachment 3 and console 2 are mutually, vertically displaced.
  • the bolts 5 with their heads 8 in this depiction, are now being forced into action.
  • the attachment 3 is sunken to the outer circumference of the bolt head 8 , whereby the clearance, of the otherwise annular opening, is reduced to zero at one point.
  • the holes for the screws 4 are likewise no longer in concentric alignment but are offset from one another. The boring openings, however, still suffice to provide space for the screw shafts which are situation therewithin.
  • FIG. 5 shows a detail view of a connection position in the zone of the screws 4 in their specified operational position.
  • the openings in the console 2 and the attachment 3 are in axial and concentric alignment.
  • the screw 4 by means of a nut 11 , its shaft 12 and the screw head 13 threadedly binds the connection surfaces of the console 2 and the attachment 3 .
  • the contacting surfaces, which have the coating 9 , 9 ′ are securely bound with one another and in this way create the frictional connection between the console 2 and the attachment 3 .
  • the coating 9 , 9 ′ in this embodiment, is also on the contacting surface of the attachment 3 , to bring about a particularly effective frictional connection.
  • Between the shaft 12 and the screw boring 14 is an annular opening of sufficient size.
  • This annular opening is particularly of advantage if it can reach to the extent of a maximum of 3 mm. That is to say, in a concentric coincidence, a diameter difference of 3 mm exists and thus is larger than the annular opening between the bolt opening 10 and the bolt head 8 .
  • the displacement possibility of the screw 4 in the screw boring 14 is so to be designed, that it is indeed greater than the sliding displacement of a bolt head boring 10 .
  • FIG. 6 a failure situation is shown. In this case, the frictional connection became no longer sufficient, so that the attachment 3 was caused to slide along the console 2 downward. In the present presentation of the FIG. 6 the attachment 3 lies against the (not shown) bolt head 8 . Since the annular openings on the bolt head 8 and the opening 10 are less than the annular opening between the screw shaft 12 and the screw-boring 14 , the attachment 3 , in this illustration, does not seat itself on the screw shaft 12 .
  • the vehicle which runs over the damaged binder position, can receive/transmit data in regard to, first the retention of the specified operational state, second the attainment of the first redundant system, and third the achievement of reaching the second redundant system.
  • a reaction to such a signal can be, that by the determination of the occurrence of the first redundant system, a track service group can rework/replace the frictional connection and upon determination of the of the second redundant system, travel operation can be stopped on the basis of safety.
  • the present invention is not limited to the embodiment presented in the description.
  • the first redundant system can be designed in a different manner, for example, individually shaped edges on the console or in the attachment are possible, and these can be so positioned that thereby a shape-fit connection is created.
  • the establishment of the redundant system can again be accomplished by an opening, annular or of a different shape, for instance, a rectangular form.
  • marking and holding elements such as, for example, tensioning clamps or the like can be used.
