Definitions

  • the invention relates to a vehicle crane with an undercarriage and a rotatably mounted on this superstructure with a device for receiving ballast.
  • ballast While the ballast is located at the rear of the superstructure during the crane operation, it is removed during the transport journey of the vehicle crane from the superstructure and stored on the undercarriage or on its own transport vehicle to meet the axle loads of the undercarriage.
  • facilities for receiving the ballast known. These generally have at right angles to the superstructure arranged hydraulic cylinder assemblies which are connectable to the respective ballast or ballast pallets to lift them to the superstructure.
  • the object of the invention is to provide a vehicle crane, in which the means for receiving the ballast can be integrated to save space in the superstructure of the vehicle crane possible.
  • the means for receiving ballast consists of at least three vertical up and down movable traction means which are connectable to a ballast carrying pallet or base plate below the overall center of gravity of the ballast, to use the pallet or base plate to the superstructure and to connect with him or leave this.
  • this traction means deposited on a pallet or base ballast can be safely picked up and down even at high center of gravity and it is particularly advantageous that the ballast can also be picked up from the ground here.
  • the traction means can run horizontally in the revolving stage of the superstructure and be sheared several times. Due to the multiple shearing, for example, a double shear, the double stroke movement of the ballast can be performed with appropriate movement of the traction means in the longitudinal direction of the superstructure.
  • At least one hydraulic cylinder can be arranged horizontally or slightly inclined in order to move the traction means up and down by lengthening or shortening. This horizontal or slightly inclined installation in the revolving stage of the superstructure ensures that the revolving stage does not build up.
  • each case form a hydraulic cylinder with the associated ropes, the pulleys and the balance rockers a structural unit, which can be inserted for mounting in the revolving stage and with this verbolzbar.
  • a structural unit which can be inserted for mounting in the revolving stage and with this verbolzbar.
  • four balancing wings usually two units are provided, which are laterally installed between two side walls in the revolving stage.
  • FIG. 2 is a turntable 10 of a vehicle crane shown, in which a turntable 12, a rocking cylinder 14 is formed for the boom not shown here and a hoist winch 16 in the usual manner.
  • a device 18 for receiving ballast is integrated.
  • This unit 18 is designed as a structural unit and can be installed as a whole between two side walls 20 (only one is shown here) of the revolving platform 10.
  • An assembly 18 consists of a hydraulic cylinder 22, which is installed horizontally in the revolving stage shown in the embodiment shown here. Furthermore, here horizontally extending ropes 24 are reeved twice between rollers 32.
  • balancing wings 26 On the ropes are, as in FIG. 2 illustrated balancing wings 26 arranged, here two balancing wings are shown. In total, therefore, when doubling the corresponding ballast receiving devices 18 four balancing wings 26th
  • the balancing wings 26 can be moved up and down by shortening or lengthening the ropes. In the lowered position they are in FIG. 1 shown while in the FIG. 2 are shown in the raised position.
  • the shortening or lengthening of the cables takes place via the hydraulic cylinder 22 FIG. 1 the hydraulic cylinder 22 is fully retracted, so that the ropes 24 and thus arranged on this balancing wings are completely lowered. In this position, they can be bolted to a pallet 27, each receiving ballast plates 27 on its sides.
  • the ropes 24 are pulled up, so that the balancing wings 26 in the position according to FIG. 2 be pulled up.
  • the pallet 27 comes into a position immediately below the revolving stage, in the mounting tabs 30 dive into corresponding recesses of the range and can be bolted there with the pallet. In this position, the ballast is ready for use connected to the superstructure. The ballast is discharged in reverse order.
  • the structure of the ballast receptacles 18 is shown in more detail.
  • a cable guide tray 40 for the lower cables 24 and from the FIG. 4 a cable guide tray 42 for guiding the upper ropes.
  • the hydraulic cylinder 22 is retracted, so that the ropes 24 are pulled out in this position and the ballast plate 27 is moved downward.
  • the ropes 24 are deflected around the rollers 32 and moved along the tracks 40 and 42.
  • the cable guide trough 42 for the upper cables 24 is extendable.
  • the ballast can be safely absorbed even when the center of gravity of the ballast is high.
  • the ballast in the case of the ballast proposed here, can be picked up directly from the ground, so that the placing of the ballast blocks 28 can take place at a low height.
  • the ballast can be placed directly on the transport vehicle without any additional auxiliary crane. At a new job site, the ballast can then be picked up again directly from the transport vehicle. This is particularly advantageous when installing wind turbines.
  • the ropes 24 are broken down into a total of eight band ropes, each of which in turn consists of five individual ropes. This has the advantage that the pulleys 32 can be made very small in terms of their diameter ratio, so that these pulleys or pulleys 32 can be accommodated in the relatively low available height.
  • the ballast When pulling up the ballast 27 to the revolving platform 10, the ballast is self-centering by the ballast under the four attachment points auspendelt.
