Definitions

  • the invention relates to a lifting device having a turntable and two lifting elements for a transfer device for counterweights on jib cranes, in particular mobile telescopic cranes, with a rotatable superstructure, the lifting elements being provided with a vertically extendable member which is retracted into openings in the counterweights and non-positively by means of a rotary movement therewith can be connected.
  • the particular safety of the lifting device according to the invention is due to the fact that the counterweight lifting cylinder can only be rotated in the extended position because the square located at the upper end of the counterweight lifting cylinder is then located within the lower, rotatable cylinder cage. As long as the square is in the upper, fixed cylinder cage, rotation of the counterweight lifting cylinder is impossible. Incorrect operation is therefore completely excluded.
  • a concentrically arranged inductive displacement sensor is provided in the interior of the lifting elements and the piston rod head of each lifting element has a bore through which the cable of the inductive displacement sensor is led out.
  • the lifting device can thus be monitored electronically. The same operations are carried out in the lifting device according to the invention as in the known lifting devices.
  • the crane operator no longer needs to leave the crane cabin on the superstructure for this, but controls the work processes from his instrument panel, to which the cable of the inductive path length sensor is guided.
  • the crane operator can thus also take up the counterweight by lifting the counterweights into the "crane work” position and reversing them, namely placing the counterweights in the "crane driving" position from the crane cabin.
  • the inductive path length sensor always shows the crane operator the exact lifting status of the lifting element on the instrument panel.
  • two pressure switches are arranged on the base plate of the upper, fixed cylinder cage of each lifting element. The positions “open” and “locked” are displayed on the instrument panel via these pressure switches.
  • the piston rod head located in the upper, fixed cylinder cage of the lifting elements is provided with bores through which the piston surface and the annular surface of the lifting elements are supplied with oil.
  • This type of cylinder suspension protects the piston rod against damage, especially when it is ground as usual, and is maintenance-free.
  • both individual and several counterweights can be lifted simultaneously.
  • the jib crane 1 shown in FIG. 1 consists of the undercarriage 2, which is connected to the superstructure 4 by a flexible connection 3.
  • a lifting device 5 is attached to the superstructure 4, which carries the counterweights 6.
  • the lifting device 5 on a rotary table 7 consists of two lifting elements 8R and 8L, which have an upper cylinder cage 9 and a lower cylinder cage 10.
  • the upper cylinder cage 9 is fixedly attached to the turntable 7 by means of a base plate 11, which forms the upper part of a ball swivel connection 12, while the lower cylinder cage 10 is rotatable.
  • a counterweight lifting cylinder 13 is guided, in the lower end of which a cross pin 14 is inserted, which projects on both sides from the lower end of the counterweight lifting cylinder 13.
  • the lifting device is locked and the counterweights 6 are received by the lifting element 8R, while in the position of the lifting element 8L according to the left-hand halves of FIG. 3 and 4 the lifting device is unlocked and the counterweights 6 are placed on the chassis frame 15 (cf. FIG. 4, left half).
  • the lifting elements 8R and 8L are each provided with an actuating cylinder 16.
  • the piston rod 17 of the actuating cylinder 16 is articulated on the lower, expandable cylinder cage 10, while the rear end of the actuating cylinder 16 is connected to the turntable 7 by means of a bolt.
  • FIG. 5 shows a lifting element 8L consisting essentially of the upper, fixed cylinder cage 9 and the lower, rotatable cylinder cage 10 and the counterweight lifting cylinder 13 guided therein.
  • the cylinder cages 9 and 10 have a quadrangular cross section and are connected to one another by the ball swivel connection 12.
  • the upper part of the rotary ball joint 12 forms the base plate 11 of the upper, fixed cylinder cage 9 connected to the rotary table 7.
  • 11 holes 18 are provided on the base plate 11 for connecting the base plate 11 to the rotary table 7 (see FIGS. 2 to 4) .
  • the piston rod 17 of the actuating cylinder 16 (cf. FIGS. 2 to 4) is articulated on the lower, rotatable cylinder cage 10.
  • the counterweight lifting cylinder 13 has at its upper end a square 19 which is slidably guided in the square inner spaces of the cylinder cages 9 and 10.
  • the piston rod head 21 of the piston rod 20 is provided with bores 22 and 23, the bore 22 serving for the oil supply to the piston surface and the bore 23 serving for the oil supply to the annular surface of the lifting element 8L.
  • a concentrically arranged inductive displacement length sensor 24 is provided in the interior of the lifting element 8L .
  • Pressure switches 27 are arranged on the base plate 11 of the upper cylinder cage 9.
  • the square 19 slides downward along the square interior of the upper, fixed cylinder cage 9 and finally reaches the square interior of the lower, rotatable cylinder cage 10.
  • the cross pin 14 has moved through the openings of the counterweights 6. It is located at the end of the stroke within a cavity 28 (see FIG. 2) which is provided in the counterweights 6 and which also serves to center the counterweights 6 with one another.
  • the actuating cylinder 16 can now rotate the lower cylinder cage 10 by means of its piston stroke by means of the piston rod 17.
  • the square 19 causes a simultaneous rotation of the counterweight lifting cylinder 13, so that the transverse pin 14 inserted in its end is rotated into the locking position, that is to say a non-positive connection is established with the counterweights 6 (cf. FIG. 2).
