Definitions

  • the invention relates to a bridge underside device with a liftable and lowerable lifting tower, on which a work platform is attached, and with a chassis which has a turnable pivotable about a vertical axis, on which a support element is pivotally and adjustably mounted about a horizontal axis, wherein the support element is connected to the lifting tower with the participation of parallel arms.
  • Such a device is known from EP-A-O 156 304.
  • a so-called guide tower of considerable height is provided as the vertical support element.
  • a sliding sleeve (Fig. 8) is guided up and down by means of a lifting cylinder.
  • downwardly pivotable cantilever arms are mounted with horizontal axes, which in their horizontal position are hooked at their free ends to the lifting tower.
  • the sliding sleeve thus forms a rigid structural unit in operation with the cantilever arms and the lifting tower.
  • the height of the sliding sleeves and the cantilever arms alone determines the height of the lifting tower and the work platform.
  • truss bridges the beams on either side of which consist of alternating vertical columns and oblique struts that are connected to one another by horizontal trusses.
  • one is forced to reach with the cantilever arms through the windows formed from the column, strut and truss, above or below the oblique strut.
  • this forces different heights of the work platform, which cannot be tolerated.
  • the invention is based on the object of proposing a self-assembling bridge underside device which overlaps high obstacles at the bridge edge and oblique truss struts and nevertheless permits a change in the height of the work platform, and is simple in construction and easy to use.
  • a generic bridge underside device in that the arms form a double parallelogram and are articulated with one end on the support element and at the other end on a guide member with respect to which the lifting tower can be moved in the longitudinal direction, and that the arms relate allow a center position perpendicular to the lifting tower to swing out on both sides.
  • a relatively low support element in the form of an essentially rectangular frame is provided, on the whole of which at least four arms forming a double parallelogram are articulated directly.
  • the arms are articulated on a guide element on which the lifting tower is guided so that it can be moved vertically.
  • the arms are preferably so long that a height difference of at least about 1.5 m can be achieved between the downward and upward deflected end positions of the guide member.
  • the height of the lifting tower and the work platform carried by it can thus be changed by two mutually independent means, namely on the one hand by moving the lifting tower with respect to the guide member and on the other hand by swinging the arms up and down.
  • This double height adjustment enables the device to be used for truss bridges, because if the arms have to be swung down, the lifting tower can move up accordingly and vice versa.
  • the adjustment range of the lifting tower with respect to the guide member can be relatively small, so that a simple lifting cylinder can be used instead of a telescopic cylinder with considerable cost advantages.
  • the double parallelogram formed by the arms can preferably be actuated by means of at least one lifting cylinder acting obliquely on the arms or on the guide element on the one hand and on the support element on the other hand.
  • the turntable of the chassis and the fact that the support element is pivotably and adjustably mounted on it around a horizontal axis makes installation easier.
  • a slight change in the angular position of the support element allows a possible transverse inclination of the Compensate the roadway or a side inclination of the chassis to the roadway caused by a banquet or the like.
  • the arms can be designed to be variable in length.
  • the pivotability of the arms also has the advantage that the transport height, i. H. the height of the bridge inspection device loaded onto a vehicle for road transport can be kept small.
  • the support element is in a horizontal position and the lifting tower with the guide member is parallel above it. By tilting the arms, the lifting tower can be lowered and the overall height reduced.
  • the device described allows a particularly convenient and safe approach from the chassis to the lifting tower, in that the two lower arms are connected to one another by a floor.
  • the distance between this floor and the upper arms, which are braced transversely to one another, can e.g. B. 2 m, so that you can walk upright on the jumper.
  • Articulated balusters can be attached to the side.
  • the lower arms on the support element and on the guide element can optionally be moved into articulated eyes arranged higher.
  • the height gained reduces the headroom on the bridge. That can be done by a Extension of the support element and be countered by a V-shaped arrangement of the cross struts between the upper arms. Such a V arrangement reduces the risk of head bumping.
  • the bridge underside device described is exceptionally flexible in use. Lake can also be set up if the space above the carriageway, for example in the case of motorway intersection structures, is limited by a further crossing carriageway. It can overlap high obstacles on the road wheel without affecting the height of the work platform. On the other hand, when the arms are inclined downwards, the lifting tower extends extremely deep under the bridge, so that even very high bridge structures can be viewed from below from the work platform.
  • the bridge 1 has a railing 2.
  • a truck 3 which has a turntable 5 that can be rotated about a vertical axis 4, serves as the chassis.
  • a support element 7 is pivotally mounted, which is designed as a square frame through which the operating personnel can climb into the lifting tower 8.
  • a lifting cylinder 9 which is articulated at 10 on the support element 7, the support element 7 of its horizontal transport position, in which it rests on the turntable 5, pivoted into the vertical working position shown.
  • the arms 11, 12 are articulated to a guide member 13 with their left ends.
  • the respective horizontal joint axes of the upper arm 11 are denoted by 14 and 15 and those of the lower arm 12 by 16 and 17.
  • To actuate the arms or the double parallelogram formed by them serve two lifting cylinders 18 which at 19 and 20, d. H. are articulated at the top of the guide element and just below the center of the support element.
  • the guide tower 8, on the lower rotatable part of which a work platform is attached, is only shown with its upper part. Its two corner posts 21 adjacent to the bridge 1 are reinforced and designed as guide rails in which the rollers 22 or corresponding sliding elements of the guide member 13 can move along.
  • the lifting cylinder which moves the lifting tower with respect to the guide member is not shown.
  • the plan view according to FIG. 2 shows in particular the mutual bracing of the two upper arms 11, namely a cross strut 23 and two struts 24 arranged in a V-shape.
  • the vertical bars of the support element 7 are connected to one another at the top by a cross head 25.
  • the guide member 13 is also formed with two legs and braced transversely.
  • the turntable 5 is only partially shown in plan view.
  • the device is dismantled into the transport position as follows: First, the work platform, not shown, is pivoted outwards and then folded up onto the lifting tower. The lifting tower 8 then rises to approximately half the height, ie approximately in its equilibrium position with respect to the arms 11 and 12. Now the support element 7 folds onto the vehicle by retracting the lifting cylinder 9; the arms 11 and 12 are in their central position at right angles to the support element 7 and to the lifting tower 8. As a result of the pivoting movement of the support element 7, the tower rises and swivels away from the bridge with its lower end and into the bridge with the upper end.
  • the turntable 5 already begins to turn during the pivoting movement, the upper end of the tower still being approximately four meters above the carriageway, so that the vehicles beneath it can pass through on the lane 3 running next to the truck.
  • the arms 11 and 12 are pivoted slightly and the guide member 13 is thereby somewhat lowered.
  • the lifting tower 8 now rests on fixed supports on the cab roof and on the rear of the vehicle.
  • the lifting movement which can be achieved by pivoting the arms 11 and 12 takes place only by actuating the lifting cylinders 18 in an exactly vertical direction.
  • the approach to the lifting tower 8 is unproblematic.
  • the arm 12 serves as a bridge or ramp, which can also be easily walked in an inclined position if an appropriately grippable grid is used. For even larger inclinations, stairs with swivel steps can also be used.
