Definitions

  • the supports - designed as ramps - are articulated on the free ends of the pivotable roadway sections.
  • the ramps fall down. This requires special measures to securely engage the ramps for coupling with the bridge bodies.
  • the locking of the lower straps is only suitable for the transmission of tensile forces.
  • a relocatable bridge is also known, the bridge sections of which are equipped with pivotable roadway sections, on the free end of which are designed as ramps or ramp plates. From this document it is also known to provide foldable carriageway sections at each end of a bridge section and, if necessary, to provide a fixed carriageway section in the middle.
  • the present invention has for its object to improve the bridge sections of a bridge of the type mentioned in such a way that the supports for the foldable lane sections and the associated foldable lane sections are quickly and safely brought into their intended position when laying a bridge without great effort can be.
  • the support is articulated about a transverse axis on the base body Has guide profile and is engaged via the guide profile with a guide element at the free end of the pivotable lane section.
  • the three main components of a bridge section - the bridge base body, the at least one foldable roadway section and the associated support - are constantly connected to one another.
  • the guide profile on the support and the guide element on the assigned roadway section always provide a clear kinematic assignment of the movable parts, which greatly facilitates automatic laying of the bridge sections.
  • the guide profile is designed as a guide groove and the guide element as a bolt engaging in the groove.
  • the guide element can also be designed as a guide roller. The interaction of the guide groove and bolt or guide roller also reliably prevents the foldable roadway section from being lifted off unintentionally.
  • the support In order to be able to use the support universally, it is preferably designed as a ramp wedge, the Guide profile is arranged above the driving surface or top of the ramp wedge.
  • the guide profile - seen in the flat state of the support and viewed from its free end in the direction of the transverse axis - has a course which increases on average, it being advantageous if the guide profile first has one has a short, steep course and then a course with a lower gradient. It is also advantageous if the guide profile has a section with a flat course at its end facing the transverse axis.
  • the base body has a lower chord region and is provided for this with a locking device which can be actuated via a coupling mechanism.
  • the locking device is preferably designed as a pin coupling.
  • the clutch mechanism can be actuated from the outside.
  • bridge sections are coupled to one another only with the support and the carriageway section raised, provision is further made for the support to be connected via a mechanical connection to the coupling mechanism for the locking device in such a way that the support is pivoted upward in the unlocked state of the locking device.
  • a hook coupling is provided for coupling the bridge sections for the foldable road sections.
  • the ends of the bridge are as far as possible from the bank.
  • the supports lockable in their position as ramp wedges in their flat position with respect to the bridge base body.
  • this can be brought about in that the supports have lateral bores which - with the supports in a flat position - lie in the range of movement of the bolts of the locking device of the lower chords.
  • the bridge section A shown in FIG. 1 in the design of a short bridge has a base body 1 with a lower flange 2 and wall elements 3 aligned perpendicularly to the latter tapering contour in the shape of a wedge or ramp.
  • a horizontal transverse axis 6, 6 ' is provided, around which a foldable road section 7 or 7' can be pivoted.
  • the bridge sections A, A1, A2 have two lateral lane elements 10, which - seen in plan view - through in a known manner alternately as tabs 11 and given by two cheeks 12 receptacles 13 for the tabs 11 are formed (Fig. 5 and 9). Both the tabs 11 and the cheeks 12 are provided with bores 14 and 15, respectively, which are provided for penetrating bolts 16, which couple or lock the lower chords 2 of two bridge sections A (A1, A2) when at least one is formed enable two bridge sections existing bridge (see. Fig. 2).
  • shafts 17 are mounted in the horizontal crosswise direction in the lower flange 2, each of which is firmly connected to a corresponding pivotable ramp wedge 18.
  • the length of the ramp wedges 18 - seen perpendicular to the axis of the shaft 17 - is greater than the distance f.
  • the passable length of the ramp wedges 18 is approximately 3.5 f.
  • bores 19 are arranged in the side walls of the ramp wedges, into which the bolts 16 penetrate when the ramp wedges are flat and can lock them relative to the base body 1.
  • the ramp wedge 18 On the upper side or driving surface of the ramp wedge 18 there are guide profiles 20 on each of their sides, which are provided with a guide groove 21 into which guide bolts 22 arranged at the free end of the movable track sections 7 and 7 'engage.
  • the bolts 22 can also be provided with a guide roller (not shown separately), which in turn engages in the guide groove 21.
  • the guide groove 21 has one to the driving surface of the ramp wedges 18 substantially parallel shape. If one considers a ramp wedge 18 in its flat position according to FIG. 3, the guide groove at the beginning of the wedge initially has a short, steep section 21.1, then a long section with a smaller slope and - in the area above the coupling point 9 - a short, flat section 21.3.
  • the steepest position of the ramp wedge 18 is determined by the end of the guide groove 21 (end section 21.1) and the length of the road section 7.
  • the steepest position of the ramp wedge 18 corresponds to the uppermost position of the roadway section 7 or 7 ′, which runs essentially parallel to the lower flange 2 (cf. FIG. 4). In this position, the end section 21.1 has only an extremely slight slope, so that the carriageway section 7 can be supported well even under high loads.
  • bridge sections A are coupled together to form a bridge.
  • the bridge B2 shown in FIG. 2 consists of the two bridge sections A1 and A2.
  • the foldable roadway sections 7, 7 ' have an upper belt coupling 23, which is constructed as follows: a roadway section, e.g. 7 ', the one bridge section A1 is equipped with bolts 24 with an inclined sliding surface 25.
  • the assigned roadway section 7 of the other bridge section A2 has a T-shaped hook 27 which is pivotably mounted about a horizontal axis 26. The hook 27 is pressed by a tension spring 28 against a stop 29 and held elastically in its basic position suitable for coupling.
  • the T-shaped head part 30 of the hook 27 has a concave inner surface 31 corresponding to the shape of the bolt 24 and a lower sliding surface 32 corresponding to the sliding surface 25 of the bolt 24. Due to its concave design, the inner surface 31 has a depth g as seen in the longitudinal direction of the hook 27 or the roadway section 7.
  • the bolts 16 for the coupling point 9 of the lower chords are in the end part of the base body 1, which is formed by the cheeks 12 of the lower chord, in engagement with a guide link 33.
  • the guide link is - seen from the side - U-shaped, the The plane of symmetry of the U-shape runs in the longitudinal direction of the lower chords 2 and the clear width between the upper and lower legs of the link 33 essentially corresponds to the diameter of the bolts 16.
  • Both legs - seen in plan view - have corresponding V-shaped control grooves 34 into which pins 35 arranged at the top and bottom of the bolts 16 engage.
  • the guide link 33 is pressed against the end of the base body or its lower flange 2 by a compression spring 36 supported on the lower flange 2 of the base body 1 which position (cf. FIG. 9) the points of the control groove 34 which are in engagement with the pins 35 are at a large distance from one another. In this position, the bolts 16, controlled by the pins 35, are in their outer position suitable for coupling.
  • the link 33 can be pulled against the force of the spring 36 by a tension element 37 in the direction of the center of the lower flange 2 or of the bridge body 1. In this position of the link 33, the points of the control grooves 34 which are in engagement with the pin 35 are at a short distance from one another. In this position of the backdrop 33, the bolts 16 are accordingly in their innermost, non-coupling position.
  • the tension element 37 is attached at a point on the circumference of a driving or clutch disc 38 in the form of a circular sector.
  • the clutch disc 38 is fastened on a clutch shaft 39, which can be actuated from the outside by a laying device, which is only indicated with the part 40, via a crank 39 ′ fastened to the clutch shaft 39.
  • Part 40 may e.g. be a coupling cross member.
  • a further clutch or drive plate 41 is fastened on the clutch shaft 39 and is kinematically connected via a tension element 42 to a clutch or drive plate 43 fastened on the shaft 17.
  • the tension element 42 is with the imaginary connecting line or plane of the shafts 17 and 39 "crosswise", ie when the coupling shaft 39 rotates in the sense that the bolts 16 pass into the non-coupling position, the ramp wedges 18 are over the Tension element 42, the drive plate 43 and the shaft 17 pivoted up, at least to the extent that the tips of the ramp wedge 18 lie above the shaft 17, so that a further erection of the ramp wedges when the Bridge elements A1, A2 is possible.
  • the hook 27 slides with its sliding surface 32 over the corresponding sliding surface 25 of the bolt 24 into the coupling position and is held in the coupling position by the tension spring 28.
  • the lower chord coupling (bolt 16) is released first, then the two road sections 7, 7 'are approximated by moving the bridge sections A1, A2 at least by the dimension g to such an extent that the head part 30 of the hook 27 is lifted of the base body 1 of the right bridge section A2 can be lifted over the bolt 25. Then the two bridge sections can be moved apart.
  • the bridge sections A1, A2 are pressed against each other until the ramp wedges 18 have completely erected and the carriageway sections 7, 7 'abut against one another in their highest position.
  • the spring-loaded hook 27 of one section 7 automatically snaps behind the bolt 24 of the other Section 7 '.
  • the crank 39 ' is released and the bolts 16 are pressed into their locking position by the compression spring 36. This locks both the upper and lower flange of the bridge sections.
  • the lower flange coupling is first released with the bolts 16.
  • the adjacent bridge sections 7, 7 ' are moved together by the dimension g.
  • the upper belt coupling is also released and the bridge sections A1, A2 can be separated from one another.
  • the crank 39 ' the bolts 16 are returned to their locking position and the road sections 7, 7' and the ramp wedges 18 are transferred from the "road position" to the "ramp position” in a controlled manner.
  • the hook 27 of the upper belt coupling can also be used individually, e.g. can be actuated by a Bowden cable 45 supported at 44 on the associated carriageway section 7, as a result of which lifting of the entire bridge section is avoided.
  • the other end of the Bowden cable can preferably be supported on the lower chord region 2 of the bridge section and its inner element can be actuated by the coupling shaft 39 in the manner described for the tension element 37.
