Definitions

  • the invention relates to a bridge with at least one bridge element, which has a bridge base body with beveled end faces and roadway plates which can be pivoted about an axis arranged in the region of the upper edge of the beveled end faces, ramp plates being articulated on the end of the roadway plates opposite the pivot axis and the carriageway slabs either rest on the sloping end surfaces to form a drive-up position and the ramp plates lie on the embankment base, or the carriageway slabs for connecting two bridge elements to form a bridge are pivoted away from the end surfaces and the ramp plates are pivoted downward into a substantially vertical position and the facing carriageway slabs bridge elements to be coupled can be locked directly to one another, and a lower belt lock is provided with which the lower belts of the bridge elements to be coupled can be locked.
  • the invention further relates to a device for laying a bridge.
  • Layable bridges which are used in particular as pioneer bridges, are designed in such a way that they are pushed and deposited over a river or valley cut with the aid of a vehicle provided with a laying device.
  • the bridges are either in one piece or made of as few parts as possible built in dimensions that allow transport on a land vehicle.
  • the requirement must be met that the individual sections not only can be easily joined together, but must also be designed for relatively high vehicle loads.
  • a generic bridge and a laying vehicle suitable for its laying are known from EP-OS 0 391 149 A2.
  • a bridge element or section is provided with at least one joint having an axis running horizontally and perpendicularly to the longitudinal direction of the bridge, about which a roadway section located in the end region of the section can be pivoted.
  • the roadway and the roadway section can be formed in one piece or as two parallel track lines.
  • the foldable lane sections can either be swung up so that the end thereof can be coupled and locked together with the end of the base body with another bridge element, or the lane sections are folded down on the base body and form a ramp.
  • linear motors in particular hydraulic cylinders, are proposed as adjusting devices for pivoting the roadway sections.
  • the invention has for its object to develop a bridge of the type mentioned and a laying device such that the handling when laying the bridge by the laying device can be simplified and improved without sacrificing flexibility in adapting to existing obstacle widths.
  • the roadway plates can be locked and unlocked by means of a coupling hook that the coupling hook over a Traction means can be actuated by a rotatable coupling shaft and that the lower belt lock is connected to the deck plate lock via a common actuation arrangement.
  • the joint between the roadway plate and the ramp plate is preferably prestressed by means of a spring, a torsion spring in particular having proven itself. This ensures that even in the ramp position of the carriageway slab, the pretension in the torsion spring is still so great that the tip of the ramp slab does not lie below the level of the lower edge of the bridge.
  • the locking of two lower straps is preferably designed as a bolt coupling with bolts which are displaceably guided transversely to the bridge elements, the bolts engaging in the locking position in bores of tabs or cheeks of the lower straps of the bridge elements.
  • the use of the bolt coupling enables the lower chords to be coupled easily and securely, since the connection is capable of absorbing forces occurring in the longitudinal direction of the bridge as well as transverse forces perpendicular thereto.
  • the bolts can be supported on both sides of the tabs, so that there is a favorable load case for them.
  • a coupling shaft serves as a common actuation arrangement for locking the pivotable roadway sections and the lower chords, on which a control disk with guide grooves is fitted, into which a driver pin connected to the tension element for locking the roadway plate and engaging with another, likewise Control disk having guide grooves for the bolts is connected via a linkage.
  • a linkage To optimize the guide groove or grooves, they have an involute shape.
  • crankshaft can be actuated by a clutch lever.
  • the lower belt lock is acted upon by a spring in the sense of a lock.
  • the ramp plates can furthermore preferably be fixed in the vertical position and secured against lateral displacement, adjacent roadway plates of adjacent bridge elements being supported by the relevant ramp plates articulated there.
  • support rails are provided on which the free ends of the ramp plates of two bridge elements can be guided during their movement towards one another, whereby the merging of the bridge elements is made considerably easier.
  • the ramp plates straighten up by themselves without further handling or without additional intervention and transfer the swiveling road sections into their upper coupling position.
  • a holding plate is additionally arranged above the support rail, by means of which a guide is formed with the support rail, into which lateral guide pins of the ramp plates engage.
  • a coupling rail is used in the laying device, the height adjustable, d. H. is adjustable in the vertical direction and through which the clutch lever of the crankshaft of the bridge can be actuated. By moving the clutch rail, both control disks can be actuated synchronously.
  • the bridge section or the bridge element 10 as part of the bridge according to the invention consists of a bridge support or base body 11, which has an upper cover or roof element 12 designed as a roadway and end or sloping end or support surfaces 13 on which to form a drive-up position (right side of FIG. 1) a roadway plate 14 can rest or be supported.
  • the roadway plate is connected to the bridge element 10 via a hinge axis 15, which is arranged in the region of the upper edge of the beveled end surface 13.
  • the carriageway plate has a further joint 16 for a ramp plate 17 arranged at the end.
  • the carriageway plate 14 can rise up to the same height as the carriageway 12 are pivoted so that when the ramp plate 17 is folded down, which is then in the vertical position, a connection end is created for a further bridge element.
  • a transport vehicle 18 with a laying device 18.1 which is largely known according to the prior art, is used.
  • the end slabs 14 are folded down, ie they rest on the beveled end surfaces 13.
  • the frame of the vehicle 18 also has extendable floor support elements 19 which are first extended.
  • the lower bridge element is moved forward by means of a front bridge drive in order to make room for the upper bridge element 10.2 for positioning on the laying device 18.1.
  • the upper bridge element 10.2 is first lowered to the rear (FIG. 2c) and then moved to the right until the end located above the vehicle 18 lies in the area of the opposite end of the bridge element 10.1.
  • the bridge element 10.2 is then lowered to the level of the bridge element 10.1 (FIG. 2e).
  • the two bridge elements 10.1 and 10.2 are moved towards one another and, as shown in FIG. 2f, are coupled to one another, which will be discussed later.
  • the unit formed from the two bridge elements 10.1 and 10.2 is then extended to the front, further support elements 20 being used on the sliding frame of the vehicle 18 (FIG. 2i).
  • the different phases of the bridge storage are shown in FIGS. 2m to 2o, the laying device 18.1 being largely known according to the prior art.
  • Fig. 3 shows a detail according to Fig. 2e and 2f, in which the ramp plates 17.1 and 17.2 of different bridge elements 10.1 and 10.2 are opposite at their free ends.
  • a support rail 21 arranged on the laying device 18.1 and a holding plate 22 arranged above it, thereby forming a guide into which lateral guide pins 17.3, 17.4 engage, which are fastened to the ramp plates 17.1 and 17.2.
  • the coupling lever 25 remains in the "b" position (open) during the entire coupling process, for which purpose a coupling rail 27 adjustable in the vertical direction on the laying device 18.1 is used (FIG. 4).
  • the coupling rail must have at least a length "1" which corresponds to the projected length of the ramp plate 17 or 17.1, 17.2 when viewed in a plan view.
  • the coupling lever 25 is brought into the locking position "a" shown in FIG. 4 by pivoting down or lowering the coupling rail 27.
  • the roadway plates 14 are connected to one another by means of coupling hooks 28. These are connected to a traction means 29 which can be actuated via a crankshaft 30. There are two on the crankshaft 30 Set an upper control disk 31 with guide grooves 32 in involute form, into which a driver pin 33 engages, which is connected to the end of the pulling element 29 opposite the coupling hook 28.
  • the control disk 31 is connected via a linkage 39 to a lower control disk 34, which also has a guide groove 35 in involute form, in such a way that the rotational movement of the upper control disk 31 is transmitted to the lower control disk 34 via the coupling linkage 39.
