Definitions

  • the invention relates to a cable crane with a cable crane movable under the action of a traction cable and a return cable, along which a lifting cable can be raised and lowered, the cable crane vehicle having a brake acting on the supporting cable, by means of which it can be attached to the supporting cable in its longitudinal direction can be fixed immovably, with three coaxially mounted coaxial, non-rotatable coils on the cable crane wagon, which may be combined to form a coil with three coil compartments, one of which is for receiving the return rope, another for receiving the pull rope and the third for receiving the hoist rope is used, and with a brake assigned to the coils, which can be released and fixed.
  • a cable crane is known with a cable crane wagon that can be moved along the supporting cable under the action of a pulling cable and a return cable, from which a lifting cable can be raised and lowered, the cable crane wagon having a brake acting on the supporting cable, through which it can be fixed immovably on the suspension cable in its longitudinal direction.
  • This cable crane has three coils which are rotatably mounted on the cable crane wagon, are coaxial with one another and cannot be rotated with respect to one another, and which may be combined to form a coil with three coil compartments.
  • One of the coils is used to receive the return cable, another coil to receive the pull rope and the third coil to receive the hoist rope, the compartment for the hoist rope having the same diameter as the compartment of the coil for the pull rope. Furthermore, a brake which is assigned to the coils and can be released and fixed optionally is provided.
  • the invention has for its object to provide a cable crane of the type mentioned, in which the lifting and lowering of the rope and the method of Rope crane carriage along the support rope is possible through the pull rope or the return rope and in which there is no danger that the ropes will collide, which is particularly important for the return rope.
  • this object is achieved in that the return cable is always kept under tension and that the diameter of the coil or the compartment of the coil for receiving the hoist rope is smaller than that of the coil or the compartment of the coil for the pull rope.
  • the crane truck can be moved along the support cable with the aid of the pulling cable or the return cable if the brake assigned to the spools on which the cables are wound is effective.
  • the pull rope and the return rope are kept under tension even if the cable crane wagon is moved by pull on the pull rope, since the return rope is always kept under tension.
  • This "keeping the tension under tension" of the return rope is done in a simple manner by braking the cable winch on which the return rope can be wound up. If the hoist rope is to be lowered, the traction rope is released, the cable crane wagon being fixed on the support rope by actuating the brake provided for this purpose, so that the coils twist while the hoist rope and the return rope are unwound. There is also no danger that the return rope will wrap around the suspension cable when the cable crane truck is stopped or started, since it is always kept under tension.
  • the diameter of the compartment of the spool for receiving the hoist rope is smaller than that of the compartment for the pull rope, a ratio corresponding to the diameter ratio of the spool compartments is achieved, which limits the jerk at the start of the lifting process.
  • An embodiment of the invention provides that the cable winch arranged on the ground for the return cable is coupled to one output of a differential gear, and that the other output of the differential gear can be braked to different extents.
  • an oil pump is coupled with this, which promotes in a closed circuit, and that in the circuit a control element, for. B. a valve is provided.
  • the pull rope and the lifting rope are wound in opposite directions on their spools or their spool compartment, as is known per se, the lifting rope being fully wound when the pull rope is fully unwound.
  • Figure 1 is a rope running on a support rope 1 crane truck 2 can be seen, which is pulled by a pull rope 12.
  • a pull rope 12 On an upper horizontal section of a support frame 4 of the crane truck 2, two rollers 5 are mounted, which are seated on the support cable 1.
  • the pull rope 12 is wound on a triple spool 13, in the middle compartment 14 of the same.
  • a hoist rope 15 is also wound on the triple bobbin 13, specifically in the compartment 16 thereof, and runs vertically downward over a deflection roller 6 to its other end (not shown), with which it can take up a load.
  • the cable crane wagon 2 can be locked against the supporting cable 1 by means of a (radio) remote-controlled locking device (shoe brake 8). This lock is necessary if the cable crane car 2 is stationary and the load is to be picked up or set down.
  • the cable crane car 2 can also be locked by means of a (radio) remote-controlled locking device (ratchet device 9 and stops 10, 11) with respect to the lifting cable 15, this lock being effective when the cable crane car 2 is moved.
  • a (radio) remote-controlled locking device (ratchet device 9 and stops 10, 11) with respect to the lifting cable 15, this lock being effective when the cable crane car 2 is moved.
  • a return rope 18 is wound up.
  • the triple coil 13 is assigned a brake 22 with which the triple coil 13 is fixed, i. H. can be held non-rotatably.
  • the brake 22 is coupled to the pawl device 9 via a hydraulic line (not shown).
  • FIG. 4 shows the overall arrangement of an embodiment of the cable crane according to the invention.
  • the traction cable 12 is guided via a deflection roller 23 to a winch 24, which is guided, for example, on a tractor 25, which is indicated schematically in FIG. 4.
  • the return rope 18 is guided to a winch 26 which is loaded by a drive such that the return rope 18 is kept constantly under tension.
  • a possible embodiment for the cable winch 26 for the return cable 18 is shown in FIG. 3.
  • the cable winch 26 is fastened to an output of a differential gear 27 (“differential”), the differential gear 27 being able to be driven by the PTO shaft of a tractor 28.
  • An oil pump 30 is coupled to the other output 29 of the differential gear 27 and conveys hydraulic medium (oil) in a circuit via a ring line 31.
  • a control valve 32 is provided in the ring line 31 through which the oil pump 30 delivers oil. By adjusting the control valve 32, the resistance in the ring line 31 can be changed and thus the force acting on the cable winch 26 for the return cable 18 can be regulated.
  • pulling rope 12 and the lifting rope 15 are wound on the spool 13 in their compartments 14 and 16 in opposite directions, the rope lengths being dimensioned such that when the pulling rope 12 is fully unwound, the lifting rope 15 is fully wound.
  • the parking brake 8 of the cable crane car 2 is actuated so that it cannot be moved relative to the supporting cable 1 and the brake 22 for the triple coil 13 is released.
  • the lifting rope 15 is lowered and vice versa.
