Definitions

the invention relates to a device for use in inspection and renovation work or the like on bridges with a cable car system with at least two ropes tensioned along the bridge and at least one work platform which can be moved by means of these ropes.
the object of the invention is to provide a device for use in inspection and refurbishment work or the like on underside of the bridge, which is inexpensive and does not constitute a traffic obstruction.
this object is achieved in a generic device in that for inspection and renovation work or the like the lower cableway system in the area of the lower bridge view, that the at least two cables of the cable car system are anchored to the bridge abutments, and that the work platform is at least one working platform suspended from the cables and extending transversely to the bridge. Since the working platform now hangs under the supporting structure, no structural structures are required to support the working platform on the carriageway, and the installation of a cable car system under the supporting structure is easy to carry out.
the device is characterized in that the ropes are supporting ropes which are braced on the bridge abutments and which are supported by rope shoes which are attached to the supporting structure of the bridge.
the suspension cables can be easily stretched between the bridge abutments and, depending on the length or the radius of the curve of the bridge, supported by any number of rope shoes to minimize the sag of the suspension cable to the required extent and the course of the suspension cable to the curvature to adapt the bridge in the curve area.
the working platform can then have rope pulleys according to the invention, by means of which it can be moved on the supporting ropes.
the ropes are carrying ropes that support the working platform and are connected to them, which are deflected at the bridge abutments and guided over support rollers, which, compared to the previously described embodiment, may possibly be different. can be more advantageous.
base plates are fastened to the bridge abutments and to the structure of the bridge.
the base plates on the bridge abutments have known rope anchorings and the base plates on the supporting structure have the rope shoes.
the base plates with the cable anchorings or the cable shoes can be left after the work on the bridge, however can also be removed.
the base plates can be left on the bridge abutments or on the supporting structure and the rope anchorings and the rope shoes can be removed.
suspension cables or the ropes are guided past any supports. This offers the advantage that the transfer of the working platform from a field of the bridge into a further field which is separated from this field by a support can be carried out very simply in a manner which will be explained later.
At least one traction rope is tensioned between the bridge abutments, by means of which the working platform can optionally be moved via a winch on the supporting cable.
At least one, preferably two, cable winches are arranged on the working platform, by means of which the working platform can be moved vertically by means of holding ropes, by means of which the working platform is suspended from the supporting cables or the driving cables, then the distance between the working platform and the bottom view of the structure can be adjusted as required and it is also possible that the abutments and the support surfaces are accessible from one and the same working platform.
a structure 2 of a bridge is shown in cross section.
the structure 2 is a concrete structure in the present form, but the device according to the invention can also be used for structures in steel construction or other structures.
three support cables 6, 7 and 8 are arranged on the bottom view of the supporting structure 2, which run approximately in the direction of the longitudinal extension of the bridge, and on which a working platform 1 is suspended.
three support ropes 6, 7 and 8 are used, but the number of support ropes is essentially dependent on the width of the supporting structure or the shape of the work platform, which can be adapted to the shape of the bottom view.
the work platform 1 consists of a horizontal lower part 9, an inclined part 10 and a part 11 projecting over the edge of the supporting structure 2, so that the inspection and the loading of equipment, tools and required material is possible directly from the road surface.
the work platform may be inspected or loaded by means of an independently movable access scaffold part to the side of the supporting structure.
the anchoring of the supporting cables 6, 7 and 8 takes place as in the embodiment of the device according to the invention shown in FIGS. 2 and 3 on the abutments 3 and 4 of the bridge, the anchoring being able to be carried out, for example, with the cable anchoring shown in FIG. 4.
the supporting ropes 6 to 8 are shown by rope shoes 11, which are shown in FIGS. 5 and 6 are supported.
the cable anchor 12 is detachably connected to a base plate 13, as shown in Fig. 4, which e.g. is screwed to the abutment 3 via dowels. After completion of the work, the base plate 13 can remain on the abutment 3 and be used again for new work.
a tensioning device is fastened to the rope anchorage 12 and consists of a pulley 23, a tensioning rope 14 guided around a deflection roller 21 and a weight 15.
the attachment of the suspension cable can be done using a conventional cable attachment, such as a wedge lock, attached to the rope anchor 12.
rope shoes 11 are shown, by means of which the supporting rope is supported between the abutments 3 and 4, the rope shoe 11 shown in FIG. 5 being screwed directly to the supporting structure 2, whereas the rope shoe shown in FIG. 6 11 is fastened to the supporting structure 2 by means of a base plate 16 which is firmly connected to the supporting structure 2 and is left after the work on this has been completed.
the work platform 1 is suspended via cable rollers 17, which are mounted on a roller holder 18, and holding cables 19 on the supporting cables 6 to 8, and can be moved (FIG. 6).
a stationary cable 20 is tensioned parallel to the supporting cables 6, 7, 8, on which a gripping pull attached to the working platform 1 engages.
a traction rope can be provided that is coupled to the work platform 1 (or can be coupled if required).
Rope winches which are well known in the prior art and are not shown for this reason, are fastened to the work platform 1, by means of which the holding ropes 19 can be wound up and down.
the work platform 1 can be raised and lowered vertically, so that the distance between the work platform and the bottom view can be adjusted as required, but also a vertical positioning of the work platform along the bridge abutment and any existing supports is possible.
Another very important advantage of the device according to the invention is that the transfer of the work platform 1 from one work (bridge) field into another can be carried out very simply in the following way:
the work platform 1 is lowered over the cable winches and the holding cables 19 along a support to the floor and then dismantled to such an extent that it can be moved to the other side of the support.
the support rollers can then easily be moved to the correct position in the new structure field on the other side of the support on the support cables.
the work platform is then reassembled in the new field and can be raised.
suspension cables are arranged so that they are guided past the supports from abutments to abutments.
a winch preferably operated by hand, can be used for this purpose, which winds up or unwinds one or, if necessary, two pulling ropes, which are anchored to the abutments or the supports.
driving cables guided over deflection pulleys can also be used, in which case the holding cables 19 of the working platform 1 are clamped to the driving cables by suitable devices.
the stage is moved by the movable ropes, which can be driven by a common or separate drive.
the base plates 13 and 16 can also be attached to the structure by means of bolts which are guided through bores in the concrete parts, for example the webs and the base plate, and possibly screwed in with the interposition of tabs.
