Definitions

  • the invention relates to a bridge underside device according to the preamble of claim 1.
  • Bridge underside devices are required for bridges without a built-in working platform, in order to inspect the underside of the bridge and construction parts that cannot be seen from the bridge plate and to carry out maintenance and repair work after the inspection has been completed.
  • such devices are required for concrete bridges, ie preferably for road and highway bridges, which, contrary to the original expectation, require maintenance and repair and therefore generally do not have working platforms installed from the outset. Therefore, these bridge underside devices are portable units that are capable of are to replace the otherwise required scaffolding or to enable the construction of auxiliary scaffolding on the work platform.
  • the frame assembled which includes can be done with a mobile crane, the descent tower allows you to enter and leave the work platform from the bridge slab.
  • the work platform hangs on the descent tower at a distance from the underside of the bridge plate and, if applicable, the box girder that is usual for motorway bridges.
  • each bridge field can be moved along its full length with the working platform swung in.
  • the working platform on the bridge pillars is usually swung out and swung in again after driving over a bridge pillar.
  • the frame is supported on the bridge and supports the various loads and moments acting on the descent tower and the work platform. In general, several elevations are used, which form at least two portals, which are expediently arranged at the ends of the frame.
  • the bridge should remain at least partially usable during the use of such a bridge viewing device.
  • this presupposes that the frame only takes up a fraction of the B width of the bridge plate adjoining the bridge edge.
  • a railing runs directly at the edge of the bridge, and many highway bridges are followed by an inspection walkway, a guardrail and a scratching board.
  • These Devices cannot be removed for the use of the underside bridge device.
  • the frame of the device should also largely be removed from the possible effects of traffic, especially in the event of an accident, so that collisions with accident vehicles do not endanger or even crash the workers working on the work platform.
  • the invention is based on a previously known underside bridge device (DE-OS 31 24 183, FIGS. 4 and 5).
  • the frame is supported with rollers on the edge of the bridge, on the inspection aisle and the scraping board on the top of the bridge, and this support of the frame interacts with rollers which are attached to an extension of the tower and roll on the underside of the bridge.
  • this support requires relatively long gantry beams that connect the gantry stems to roller supports and reach beyond the master corridor to the curb.
  • the rollers must be set up in such a way that they can drive on the treads they use without the descent tower with the attached work platform making excessive vibrations.
  • the invention has for its object to provide a bridge viewer of the type presupposed as known in such a way that the frame parts arranged on the bridge, regardless of the width and height of the obstacles there, claim a much smaller part of the bridge width for themselves and therefore generally behind Impact devices on the relevant bridge edge are withdrawn and thus arranged on the bridge in such a way that the risk of collision is practically excluded, at the same time creating more favorable conditions for driving onto the bridge with the frame or the work platform.
  • the clamps used to brace the frame due to the practically arbitrary clamp forces mean that only a small contact surface, which is directly adjacent to the edge of the bridge, is required for supporting the upper clamp arm.
  • the mobility of the work platform along the bridge plate is ensured on the one hand by the passability of the frame rails with the undercarriage, which supports the work platform via the descent tower, but on the other hand it is achieved by the possibility of moving the frame, which, when the undercarriage is clamped and the frame clamps released, by guiding the frame rails in the Undercarriage rollers or wheels are guaranteed.
  • the rolling properties are considerably cheaper than on concrete surfaces and therefore also enable castors or wheels with a smaller footprint, which ensure the alternating movement of the frame and the chassis along the bridge.
  • the invention has the advantage that the stationary frame represents an absolutely safe suspension of the work platform, which also safely carries off the wind loads and any dynamic loads on the work platform on the bridge, and that, conversely, the work platform remains clamped to the bridge when the undercarriage is clamped, but the frame is safely guided on the chassis.
  • the bridge viewing device according to the invention as a result of bracing instead of mere support with or wheels that can be rolled on the bridge, a practical, i.e. apart from the assembly and disassembly times not impaired traffic routing over the bridge, because neither parts of the roadway nor areas required for traffic, such as any signs of wear, curbs or the like for the frame. to be entitled to.
  • the invention also makes it possible to intercept the work platform on both bridge edges, each with a frame and a descent tower, because the two frames can be implemented synchronously and the trolleys can also be moved and stopped synchronously.
  • stretched arm arms which are arranged directly above the bridge surface and which accordingly do not bridge the railing provided, for example, at the bridge edge with an offset, but reach through between the railing supports.
  • This has the advantage that, due to the low overall height of the stretched clamp arms, the collision possibilities of the frame with crashing accident vehicles are practically eliminated, even if the accident vehicles should overcome the curb and break through the guardrail. Similar considerations also apply, of course, to other obstacles on the bridge wall, such as soundproof walls, which can be installed there.
  • the possibility is created to get by with two rails and positive rails, but which can practically form a structural unit with the running rails, existing simple track for the working platform and to ensure that the center of gravity of the tower is practically in the level of the support of the frame or the chassis, so that favorable conditions are created for the removal of the reaction forces.
  • the bridge generally designated 1
  • the bridge has the box girder 2 customary in prestressed concrete bridges and a bridge cap 3, which is equipped at the edge of the carriageway 4 with a curb 5, which can be supplemented by a guardrail, not shown.
  • the curb 5 and the guardrail then form the bridge-side boundary of an inspection passage 6, which is secured at the B back edge 7 with a railing 8.
  • the railing has the usual, according to the embodiment three longitudinal spars 9-11 and at certain intervals vertical supports, one of which is drawn at 12 in Fig. 1. Further supports 13-15 can be seen from the illustration in FIG. 3.
  • the bridge underside device generally designated 16, has a frame 17 and a chassis 18.
  • the frame has a clamp 19, 20 at each of its two ends.
  • Each ferrule surrounds the bridge edge 7 assigned to the device 16 and has an upper ferrule arm 21, a vertical ferrule cross-member 22 which runs directly in front of the bridge edge 7 when the ferrule is in place, and a lower ferrule arm 23 which is penetrated by a cylinder 24 of a thrust piston transmission which is on a console 26 is articulated on the underside of the arm 23 and carries a head plate 27 on its piston rod, which is supported on the underside 28 of the cap 3.
  • the upper clamp arm has a buffer 29, which extends in the extended axis through the cylinder 24 of the thrust piston transmission, the piston rod end plate 27 and extends the buffer as drawn at 30 in FIG. 1.
  • the clamp 19 is designed like the clamp 20 and therefore does not require a separate description.
  • Two guide rails 31, 32 connect the two clamps 19, 20 to one another. With clamped clamps 19, 20, they run parallel to the bridge edge 7 and approximately horizontally, i.e. in alignment with the top of the bridge.
  • One of the guide rails 31 is seated on the outside of the vertical clamp crossbar 22, while the other guide rail 32 is fastened to the end face of the lower clamp arm 23.
  • the guide rails have the same profile underneath them. They generally consist of a U-profile connected with its web 33 to the respective support, the respective lower leg 34 of which serve as a raceway for the cylindrical rollers of the chassis-16, while a flange 35 running parallel to the web on the lower leg 34 and the upper one Leg 36 serves as a forced rail for the rollers 37, which are guided safe against derailment. The same rail profile is used for the rollers 38.
  • the track consisting of the two rails 31, 32 is arranged such that the alignment line 30 from the buffers 29 through the piston rod end plates 27 and the cylinders 24 of the clamps 19, 20 is slightly outside the center of the track , but runs between the two rails.
  • the upper clamp arms 21 as well as the lower clamp arms 23 are stretched.
  • the upper clamp arm is pivotally mounted in a joint 40 about a vertical axis, which forms the central axis of the clamp crossmember and is designated by 41.
  • the undercarriage has a undercarriage 43 which, in a structural unit, has parallel stems 44, 45 with the roller carriers 48, 49 arranged on the facing stalk sides 46, 47, and one the crossbar connecting the stems and a likewise pivotable elongated arm 51 connects.
  • a joint 52 is provided in the arm 45 for the arm 51, the joint axis 53 of which coincides with the central axis of the arm 45.
  • the non-rotatable part of a turntable 55 is displaced, the rotatable part of which is connected to the frame of a descent tower 56, on which the work platform 58, generally designated 57, is suspended via a horizontal joint (not shown), the work platform 58 of which is attached to both Long sides with railings 59 and on the transverse side with another railing 60 is secured.
  • the upper arms 21 of the clamps 19, 20 each penetrate the lower space between the railings in the adjacent stems 12, 13, 14, 15 .... and the lower spar 11.
  • the axis 61 of the descent tower 56 is aligned with the axis of rotation of the pass-through slewing ring 55 and this in turn is aligned with the connecting axis 62: which through a cylinder 63 of a hydraulic thrust piston gear 64 mounted on the lower cross arm , the piston rod and the piston rod plate 65, which is supported on the underside 28 of the bridge cap.
  • the underside bridge device 16 is assembled with the aid of a mobile crane. It can move along the bridge in the general direction indicated by arrow 70.
  • the undercarriage 18 is first moved in the direction of arrow 71 on the track consisting of rails 31 and 32 with a drive (not shown).
  • the entire underside 72 of the bridge can then be inspected and, if necessary, renovated from the platform 58.
  • Foldable scaffolding towers (not shown) can be set up on the work platform 58 in order to be able to inspect and process the more distant undersides, such as the underside 28 of the bridge cap.
  • the undercarriage 18 When the undercarriage 18 has reached the end position shown in dash-dotted lines in FIG. 3 next to the clamp 19, the undercarriage 18 is tensioned as shown in FIG. 2.
  • the piston rod extending from the cylinder 63 serves with its head plate 65, which rests on the underside 28 of the cap and the buffer 74, which is fastened on the underside of the arm 51 of the chassis.
  • the piston rods of the thrust piston gears are moved into the cylinders 24 of the clamps 19, 20.
  • the upper clamp arms can be pivoted out of their effective position between the railing supports 12, 13 or next to the railing support 15 and placed approximately parallel to the course of the track from the rails 31, 32.
  • the frame guides with its rails 31, 32 in the rollers 37, 38 of the undercarriage and can be moved in the direction of arrow 80 (right in FIG. 3) until the clamp 20 has arrived on the left side of the undercarriage 16 is.
  • the undercarriage 18 can then be moved again in the direction of arrow 70 along the rails 31, 32 after the clamps of the undercarriage have been released and swung out.
  • the device can drive the entire bridge. If bridge pillars have to be passed, the descent tower 56 in the turntable 55 is pivoted such that the stage 57 is oriented parallel to the bridge. Behind the pillar, it can be swung back into the operating position described in connection with the figures ken. Therefore, the device does not need to be reassembled when passing bridge piers.
