Definitions

  • the invention relates to a bridge underside device with a chassis, an intermediate support attached to the chassis, a guide member rotatably mounted on the intermediate support about a horizontal axis of rotation, a lifting tower accommodated by the guide member and movable vertically to its axis of rotation with four corner spars, and one on the lifting tower about its longitudinal central axis rotatably mounted lower part of the lift tower and a work platform attached to it.
  • the intermediate carrier is a carriage which can move transversely on the chassis.
  • the lifting tower has a square cross section.
  • the disadvantages are the high space requirement, which makes it difficult to close the device tightly during transport, and the unfavorable weight distribution due to the symmetrical lifting tower cross section.
  • the invention has for its object to propose a compact and versatile self-assembling underside bridge device with increased stability.
  • this object is achieved according to the invention in that the guide member has a flat shape and is in sliding engagement only with the two adjacent corner bars of the lifting tower, and that these corner bars are designed for a higher load capacity than the other two Corner pillars.
  • Racks can also be attached to the loaded corner spars, which work together with a rack and pinion drive on the guide element to drive the lifting tower.
  • the guide member is preferably mounted on the intermediate carrier by means of a turntable, which is preferably also flat and plate-shaped.
  • the guide member In order to extend the lifting tower close to its free end, the guide member preferably has a shorter section with respect to its axis of rotation to the free end of the lifting tower and a longer section facing the work platform.
  • the intermediate carrier be mounted on the chassis by means of a lever parallelogram that can be pivoted about vertical axes and consists of at least two levers.
  • the unit which is folded up during transport and consists of the lifting tower and the work platform, loads parallel to itself above the edge of the bridge and then swings around the horizontal Set up the axis of rotation.
  • the parallel levers are preferably telescopic.
  • a third, preferably slightly higher, parallel lever can also be provided. If these three parallel levers can be individually telescoped and detached from the intermediate carrier, columns or masts arranged on the edge of the bridge can be bypassed by alternately pulling back the parallel levers with the bridge underside device installed. In the swung-out state, the parallel levers only have to be so far apart from one another that the mast in question finds space between them.
  • a major advantage of this design is that the work platform can be folded out of the lift tower from a work position parallel to the bridge and can accordingly be transported lying on the lift tower with the floor up.
  • the intermediate girder be attachable to the narrow side of a mobile portal scaffold. It can be the same intermediate carrier that is otherwise articulated on the parallel levers of the chassis. Instead, it is connected to length-adjustable cantilevers of the portal scaffolds, which are expediently attached to a carriage that can be moved in the vertical direction on the portal scaffold. To bypass lampposts or the like, three cantilevers which are arranged at horizontal intervals and can be individually length-adjusted and detached from the intermediate carrier can also be provided here.
  • a further proposal amounts to taking the load-bearing portal on the same road transport vehicle as the rest of the device.
  • the portal frame is preferably horizontal and transverse to Direction of passage telescopic and provided with castors. It has an opening for a road vehicle on one narrow side, onto which a structural unit consisting of the intermediate carrier, the guide element, the lifting tower and the work platform is loaded. Suitable connecting elements are provided for this purpose in order to additionally accommodate the portal scaffolding on this road vehicle.
  • the receiving devices for the intermediate carrier and the other components of the device are attached.
  • the device according to Figures 1 to 6 is built on a five-axle semi-trailer, which also serves as a transport and operating chassis. With the help of the air pressure suspension device of the three central axles, the chassis 1 is raised so far during road transport that the wheels 2 and 3 of the unsprung outer axles stand out from the road.
  • the lifting tower 4 has a rotatable lower part 5 of the lifting tower.
  • the work bridge 7, which has a telescopic additional bridge 8, is articulated about a folding axis 6.
  • the lifting tower 4 is guided in a longitudinally movable manner on an elongated flat guide member 9 with its corner spars facing this guide member.
  • the reinforced bars have a corresponding cross-sectional profile and, in the case of a rack and pinion drive, a rack.
  • the guide member 9 is rotatably mounted on a flat intermediate support 11 about a horizontal axis of rotation 12 by means of a turntable 10. Precautions have been taken to ensure that a rotational movement of at least 270 ° is possible in both directions.
  • the intermediate carrier 11 is mounted on the chassis 1 by means of two parallel levers 13 and 14.
  • the chassis-side joints are located on a bearing block 15. The joint axes run perpendicularly, so that the intermediate carrier 11 and with it all other parts can be lifted laterally from the chassis parallel to itself in their transport position.
  • Fig. 4 shows the completed unloading movement at the edge of a bridge 16.
  • a third parallel lever 18 is shown here to demonstrate the avoidance of lampposts 17 or the like at the edge of the bridge the other two and is arranged slightly raised. By swiveling the parallel levers a little more than 90 °, the parts of the device that were still folded were raised beyond the edge of the bridge, where they are initially still in a horizontal position.
  • the work platform 7 is at the top and, as also shown in FIG. 3, has its bottom up.
  • the lower part of the lifting tower 5 initially points to the left.
  • the lifting tower is now turned to the right (arrow in Fig. 5).
  • the work platform 7 hangs freely downwards and detaches from the tower during the further rotary movement. 5
  • the tower has already covered an angle of 150 °.
  • the edge of the work platform on the lower part 5 of the lift tower, designated 19, comes to rest.
  • the work platform no longer moves with respect to the tower.
  • it is horizontal and can be pivoted under the bridge after the lifting tower 4 has been lowered accordingly.
  • the additional web 8 extends. 6 shows this working position as seen from the pillar of the bridge.
  • the device is dismantled in the reverse order and with the direction of rotation in relation to the axis of rotation 12.
  • lampposts 17 can be bypassed in the assembled state of the device.
  • all three parallel levers are telescopic and individually detachable from the intermediate carrier 11.
  • the arrangement is such that two parallel levers alone can carry the bridge inspection device.
  • the figure shows how the parallel lever 13 is released from the intermediate carrier and is retracted as long as the chassis moves to the left until the lamppost 17 is between the parallel levers 13 and 18. In this position, the parallel lever 13 is coupled again and the parallel lever 18 is withdrawn, etc.
  • FIGS. 7 to 10 works with a portal frame that can be moved on castors, consisting of a horizontal upper part 20 and two side parts 21 and 22.
  • the upper part has two telescoping sections 23 and 24, each of which is firmly connected to a side part .
  • These sections can consist of telescopic tubes, lattice masts, a lattice work or the like.
  • a three-axle truck serves as a pure transport vehicle. On the one hand, it carries a structural unit consisting of intermediate support 11, slewing ring 10, guide member 9, lifting tower 4 and work platform 7 as described in the first example and in FIG. 1 and, on the other hand, the portal frame retracted to its shortest position.
  • Legs 25 equipped with castors are folded up at the four corners.
  • the unit is lower than the portal frame with the legs folded up.
  • the two side parts of the portal frame are designed differently.
  • the side part 21 forms a large opening, so that, according to FIG. 8, after the legs 25 have been unfolded, the portal frame stands on the roadway, in particular a bridge, and the truck can extend through the opening of the side part 21.
  • the further assembly process results from FIGS. 9 and 10.
  • the portal scaffold is first unloaded in the direction of travel, ie in the longitudinal direction of the bridge, and then rotated with the aid of its steering rollers (dash-dotted in FIG. 9) until it assumes a position transverse to the bridge. Now the truck also moves in the longitudinal direction of the bridge and thus parallel to the side wall 22 of the portal scaffold.
  • the horizontal, telescopically extendable arm 26 has. These are connected to the hinge eyes of the intermediate carrier 11. By raising the carriage mentioned on the side part 22, the assembly is lifted off the truck and the truck can move away. Now sections 23 and 24 of the portal scaffold upper part are moved apart until the side part 22 comes to rest on the edge of the bridge and the portal scaffold spans the entire street. If necessary, the arms 26 can also be extended further, so that the structural unit is raised above the bridge and initially still held horizontally on the portal frame. This is shown in FIG. 10. The further construction of the device takes place as described in the first example.
  • the device according to FIGS. 11 to 16 consists of a chassis in the form of a trailer 30, on which a turntable 31 is rotatably mounted a little behind the center about a vertical axis 32.
  • a weight 33 on the shorter end of the turntable 31 pointing forward and on the rear end a guide member 35 is rotatably mounted about a horizontal axis of rotation 36 by means of a turntable 34.
  • a lifting tower 37 loads on its corner spars provided with toothed racks move in the longitudinal direction.
  • a pinion is attached to the guide member 35.
  • a square corner segment 39 is rotatably mounted about an axis of rotation 40 by means of a further rotating ring 38, which extends in the direction of the central axis of the lifting tower.
  • a work bridge 41 and an additional bridge 42 pushed into it are fastened to the corner segment.
  • the bottom of the work platform, which can thus rotate in a horizontal plane around the lifting tower 37, is at the top in this transport position.
  • the lifting tower can be raised until its lower end almost reaches the guide member 35.
  • a further lifting tower segment 43 which also contains a rack section, at the bottom, for example by bolting.

  • the additional web 42 can be extended so that the working web thus reaches its full length. Since the work platform floor is, as mentioned, at the top, provision is made according to FIG. 12 to attach foldable additional railings 45 and 46 to the work bridge 41 and to the additional bridge 42.
  • the work platforms can be climbed through the lifting tower 37 and the slewing ring 38.
  • the high-work platform constructed in this way according to FIG. B. for repairs to a gantry bridge or another bridge that spans or crosses the carriageway.
