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 displaceable perpendicular to its axis of rotation with four corner spars, one on the lifting tower around its longitudinal central axis rotatably mounted lower part of the lift tower and a work platform attached to it.
  • the lifting tower has a symmetrical, in particular square, cross-section and the guide element encloses it all around.
  • a guide element with a hollow cross section, which takes up the tower cross section is also referred to as a guide box.
  • 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 corner bars of the lifting tower adjacent to it, and in 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 to 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 from at least two levers.
  • 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 lever with the bridge underside device installed. In the swung-out state, the parallel levers only have to be so far apart from each other 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 arranged at horizontal intervals, individually length-adjustable and detachable 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 a narrow side, on 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 basic idea of the invention also has a favorable effect in a combined device according to the following proposal, which can be used either as a deep working platform, in particular for the cap area of bridges, or as a high working platform.
  • the rotational movement of the guide element and its horizontal axis extend over at least 180 °.
  • the lifting tower can be brought into two vertical positions with opposite orientation, so that the work platform fixed in this case at right angles to the lifting tower is located in one position at the bottom and in the other position at the top, the work platform being designed for double-sided use. It can be turned around its longitudinal axis or can be equipped with a floor that can be used on both sides, additional railings being provided that can be folded around the floor longitudinal edges.
  • the lifting tower assumes the vertical position with the work platform at the top during the transport journey, the railings pointing downward.
  • the intermediate carrier can be on a around a vertical axis pivotable turntable of the chassis. This turntable is preferably so long that the guide member protrudes beyond the chassis outline in each of its positions.
  • the angle of rotation range of the rotary drive of the guide member is at least 270 °, which makes it possible for any bridge underside devices with a work platform that can be folded up onto the lifting tower
  • Hydraulic cylinders or cable winches are usually installed for this purpose. If the direction of rotation is selected correctly, the folding and unfolding of the work platform moves freely in accordance with the rotary movement until the angle lock is reached.
  • FIG. 1 is a side view of a bridge underside device loaded on its chassis for road transport
  • FIG. 2 shows the top view of the device according to FIG. 1,
  • FIG. 3 shows the view of the device according to FIG. 1 in the direction of travel
  • FIG. 4 shows the top view of the device according to FIG. 1 after the parallel arms have been pivoted out

  • Bridge underside device in the loading position on a road transport vehicle
  • FIG. 9 is a plan view on a scale like FIG. 8 with two further intermediate positions during assembly,
  • Fig. 10 is a plan view like Fig. 9 with another
  • Fig. 11 is a side view of a combined portrait
  • FIG. 12 is a view of the device of FIG. 11 in the operating position as a high-work platform
  • FIG. 13 shows the top view of the device according to FIG. 11 when it is provided as a deep working platform
  • Fig. 15 is a side view in the operating position as a deep working platform along the edge of the bridge and Fig. 16 is a view of this device in
  • 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 middle 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 lifting part 5.
  • the work bridge 7, which has a telescopic additional bridge 8, is articulated thereon 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. 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 by a little more than 90 °, the still collapsed parts of the device were raised beyond the edge of the bridge, where they are initially still in the horizontal position.
  • the work platform 7 is at the top and, as also shown in FIG. 3, has its bottom up.
  • 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 withdrawn 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 castors (dash-dotted in FIG. 9) until it assumes a position transverse to the bridge.
  • the truck now 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 joint liquors of the intermediate carrier 11.
  • the assembly is lifted off the truck and the truck can move away.
  • Sections 23 and 24 of the upper part of the portal scaffold are now moved apart until the side part 22 comes to rest on the edge of the bridge and the portal scaffold spans the entire street.
  • 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 at the shorter end of the turntable 31 pointing forward and at 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 can be moved in the longitudinal direction on its corner spars provided with toothed racks.
  • a pinion is attached to the guide member 35.

  • a further lifting tower segment 44 can be attached, which is shown in FIG. 12.
  • the lift tower segments can be accommodated on the trailer 30 and carried to the construction site.
  • the additional web 42 can be extended so that the working web thus reaches its full length. Since, as mentioned, the work platform floor is 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. used for repairs to a gantry bridge or another bridge spanning the roadway across or at an angle.
