Definitions

  • the present invention relates to a working device with a mobile and length-adjustable boom, which is pivotable at one end with a vertical plane and rotatably mounted about a vertical axis, with a rectangular work platform attached to the boom end and surrounded by a railing.
  • the mobile jibs are so-called self-propelled tire cranes, which means that the work platform for road transport must be carried on a special vehicle or that the tire crane must be accompanied by special safety organs due to excessive dimensions.
  • the object of the present invention is to improve a working device of the type mentioned in such a way that the working platform can remain on the boom during road transport without the vehicle receiving excessive dimensions.
  • this object is achieved in that at the end of the boom a carrier is pivotally mounted with one of its two ends about a first axis perpendicular to the longitudinal axis of the boom and parallel to the boom pivoting plane, such that the carrier can be pivoted parallel to the side next to the boom so that the carrier on the other End of a second axis parallel to the mentioned first axis forms, around which the work platform is pivotally connected to the carrier, that the railing and the work platform are designed to be foldable in a plane parallel to the second axis and can be pivoted laterally about the second axis next to the boom.
  • 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 rope (not shown) are attached.
  • the axes of rotation 4 of the guide rollers 2 and 3 projecting laterally beyond the crane boom 1 are flattened at the top and bottom and penetrated with bores 6 for receiving plug pins 7.
  • An adapter 8 has two pairs of arms arranged one above the other. 9 and a support frame 10.
  • the arms of each pair of arms reach on opposite sides at the end of the boom and, with their forked ends, overlap or underneath, the laterally protruding ends of the axes of rotation 4 of the deflection rollers 2 and 3 and are provided with the corresponding coaxial holes 6.
  • the '' adapter 8 is fastened to the boom 1 by means of plug pins 7 inserted into the bores. If the socket pins 7 are pulled out on one side of the boom, the adapter can. ter 8 about a first pivot axis 5, formed by the socket pins 7 of the other side of the boom, like a door leaf can be swung backwards.
  • each pipe clamp bearing 11 has a lower half shell firmly connected to the support frame 10 and an upper half shell which can be pivoted away.
  • two coaxial pipe clamps camp 13 arranged, which serve to accommodate a pipe section 14.
  • the pipe sections 12 and 14 are firmly connected to one another by a strut 15 to which an upper and a lower articulated strut 16 and 17 are 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 (see FIGS. 3 to 5) are releasably connected at 26 to the front railing 25 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 on the work platform 23 at 27 and, as shown in FIGS. 4 and 5, can be folded against the work platform 23.
  • the work platform 23 in turn is 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 work platform 23 are described in FIG
  • the frame 22 can be pivoted through 90 ° about the axis 19, so that it lies parallel to the articulated struts 16 and 17.
  • the joint struts 16 and 17 can be put together with the frame 22 to the rear about the first axis 5 in a.
  • Boom 1 parallel position can be pivoted, 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 connected in an articulated manner 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 which acts on the strut 15 on the one hand and on the articulated strut 16 in another way.
  • the working platform 23 can be attached to the adapter 8 in a simple manner, by lifting it slightly Working platform (Fig. 7) first the upper pipe section 12 is placed in the lying, fixed bearing shell halves 32 and then the entire support is pivoted down until the pipe section 14 lies in the lower, fixed bearing shell halves 33. Then the movable halves of the storage rack can be closed and screwed to the fixed halves of the bearing shell.
  • the side railings 24 ' are pivoted at 26' 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 correspondingly coaxially eyelets on the side rail 24 and on the frame 22 'is stuck.
  • the side railing 24 ' can be pivoted about the axis 26' against the front railing 25 ', the pivot axis' 26 'being offset so far from the plane of the front railing 25' that the pivoted side railing 24 'lies flat against the front railing 25', that is, its inside comes to lie on the inside of the front railing 25 '.
  • the two side railings 24 ' have been pivoted against the front railing 25' after the pins 35 have been pulled out, the latter, together with the former, can be pivoted about the axis 27 ', their distance from the working platform. 23 being selected such that that the side railings 24 'lie evenly on the upper side of the platform with its outer side, so that the working platform 23', the side railings 24 'and the front railing 25' touch one another in parallel alignment. Thereafter, the working platform '23' is 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 work platform 23 ', the frame 22', the side railings 24 'and the front railing 25' lie on one another like plates in a packet-like manner and without a gap, so that the work platform, when pivoted into the transport position shown in broken lines in FIG Takes up minimum space.
