Definitions

  • the present invention relates to an implement according to the preamble of patent claim 1.
  • Such an implement is described for example in GB-A No. 1537771.
  • the telescopic boom is flagged and lowered into a horizontal position during road transport.
  • the carrier and the work platform can be swiveled either diagonally forwards in the direction of travel, namely over or next to the lying boom or in the extension thereof to the rear. If the jib is part of a larger pneumatic crane, this will exceed the maximum permissible transverse or longitudinal dimensions of the working device for road transport, so that special rules and special routes must be observed for moving it on public roads, since driving under bridges or driving through tunnels or other restrictions is only possible to a limited extent.
  • US-A No. 3196979 discloses a working device in which a working platform is suspended in a hanging manner by means of a pivoting lever at the end of the jib of a pneumatic crane. In the transport position in which the jib is retracted and lowered, the working platform is placed on top of the lying jib, which increases the transport height of the implement and makes it difficult to move it on public roads.
  • the object of the present invention is to improve a working device of the type mentioned at the outset in such a way that the working platform can remain on the boom during road transport without the longitudinal or transverse dimensions of the vehicle being changed significantly and displacement on public roads being made more difficult.
  • reference numeral 1 denotes the telescopic boom of a self-propelled pneumatic crane known per se, at the ends of which the two deflection rollers 2 and 3 for the crane cable (not shown) are attached.
  • the axes of rotation 4 of the deflecting rollers 2 and 3 projecting laterally above the crane boom 1 are flattened at the top and bottom and penetrated with bores 6 for receiving plug pins 7 for connecting a support T.
  • An adapter 8 of the carrier T has two pairs of arms 9 arranged one above the other and a support frame 10.
  • the arms of each pair of arms reach on opposite sides past the end of the boom and, with their forked ends, overlap or underlap the laterally protruding ends of the axes of rotation 4 of the deflecting cranks 2 and 3 and are provided with the bores 6 corresponding, kaachsiale bores.
  • the adapter 8 is fastened to the boom 1 by means of plug pins 7 inserted into the bores. If the plug pins 7 are pulled out on one side of the bracket, the adapter 8 can be pivoted backwards about a first pivot axis 5, formed by the pins 7 of the other side of the bracket, like a door leaf.
  • each pipe clamp bearing 11 has a lower half shell firmly connected to the supporting frame 10 and an upper half shell which can be pivoted away.
  • two coaxially aligned pipe clamp bearings 13 are arranged, which serve to receive a pipe section 14.
  • the tube pieces 12 and 14 are connected by a strut 15 fixed to one another, are located at the upper and lower joint strut 16 and 1 7 is articulated.
  • the other ends of the articulated struts 16 and 17 are articulated on a pivot bearing housing 18, which forms a second pivot axis 19.
  • a pivot shaft 20 is rotatably mounted, which is firmly connected to tabs 21 at the top and bottom.
  • a frame 22, to which a work platform 23 is fastened, is also firmly connected to the tabs 21.
  • the work platform 23 is fenced by the frame 22 and by two side railings 24 and a front railing 25.
  • the side railings 24 are releasably connected to the front railing 25 at 26 (see FIGS. 3 to 5) and articulated on the frame 22 such that they can be pivoted against the frame 22 and in its plane parallel to the axis 19.
  • the front railing 25 is articulated at 27 on the work platform 23 and, as FIGS. 4 and 5 show, against the work surface form 23.
  • the work platform 23 is in turn articulated to the frame 22 at 28 and can be pivoted together with the front railing 25 into a position parallel to the frame 22 (FIG. 5). If the railings 24 and 25 and the working platform 23 are folded in the manner described, the frame 22 can be pivoted about the axis 19 by 90 ° so that it lies parallel to the articulated struts 16 and 17. If the plug pins 7 are pulled out on one side of the boom 1, the articulated struts 16 and 17 together with the frame 22 can be pivoted rearward about the first axis 5 into a position parallel to the boom 1, as shown in FIG. 6. In this transport position of the working platform 23, it can be transported on the boom 1 without any special measures.
  • the two hinge struts 16 and 17 are articulated by a cross strut 29 which divides the upper hinge strut 17 into two parts, one part 30 of which is telescopically adjustable in length and consists of a hydraulic cylinder piston unit 30.
  • the inclination of the work platform 23 can be changed by adjusting the length of the articulated strut part 30.
  • the inclination of the articulated struts 16 and 17 can be adjusted by means of a hydraulic cylinder piston unit acting on the strut 15 on the one hand and on the articulated strut 16 on the other hand.
  • the work platform 23 By actuating the cylinder piston units 30 and 31 (with the crane boom 1 fully retracted), the work platform 23 can be lowered to the floor in a horizontal orientation, which makes it easier for a work trail to enter the work platform 23.
  • the fixed bearing shell halves are arranged horizontally, whereas the fixed bearing shell halves 33 of the lower pipe clamp bearings 13 are arranged in an upright position.
  • the work platform 23 can be attached to the adapter 8 in a simple manner by first inserting the upper pipe section 12 into the lying, fixed bearing shell halves 32 with the work platform slightly raised (FIG. 7) and then pivoting the entire support downwards until the pipe section 14 lies in the lower, fixed bearing shell halves 33.
  • the movable half-shells can then be closed and screwed to the fixed half-shells.
  • the side railings 24 'at 26' are pivotally articulated about an axis on the front railing 25 'and can be firmly locked at the free end by a pin 35 to the frame 22', the pin being provided by correspondingly coaxial eyelets on the side railing 24 'and on the frame 22 'is inserted.
  • the side railing 24 ' can be pivoted about the axis 26' against the front railing 25 ', the pivot axis 26' being offset from the plane of the front railing 25 'to such an extent that the pivoted side railing 24' lies flat against the front railing 25 ', ie comes to lie with its inside on the inside of the front railing 25 '.
  • the two side railings 24 ' can be pivoted about the axis 27 ', their distance from the working platform 23 being selected such that the side railings 24 'lie evenly on the upper side of the platform with its outside, so that the working platform 23', the side railings 24 'and the front railing 25' touch one another in parallel alignment.
  • the working platform 23 ' is then pivoted 90 ° about the axis 37 against the frame 22', the offset of the axis 37 again being chosen such that the front railing 25 'comes to lie parallel to the frame 22' with its outside.
  • the working platform 23 ', the frame 22', the side railings 24 'and the front railing 25' lie on top of one another like plates in a packet-like manner and without a gap, so that the working platform, when pivoted into the transport position shown in broken lines in FIG. 2, occupies a minimum of space.
