Definitions

  • the invention relates to a crane winch according to the preamble of claim 1.
  • the invention further relates to a method for lifting and lowering an element, in particular a soil treatment device, by means of a crane with a supporting cable, according to the preamble of claim 9.
  • a generic crane winch which comprises a winch body with a holder for connecting this winch body with a crane suspension rope via a hook attached to the suspension cable end.
  • an electrically driven cable drum is rotatably mounted, around which a winch rope can be wound, at the other end of a winch hook is attached.
  • a portion surrounded the winch rope is formed, which defines the discharge point of the rope.
  • perpendicular to the cable direction there is a channel in which there are two unlockable snap-in pins opposite each other, which can engage in a ring slot on the upper part of the winch hook.
  • a portable winch device which is securable for operation on a log.
  • An internal combustion engine drives a hydraulic motor via a hydraulic pump circuit, which rotates a winch spool via a gearbox.
  • the winch coil in turn drives a shaft via a gearbox rotating, which shifts a Verschiebekulisse parallel to Windenspulenachse.
  • the roll-up cable is guided through a provided with horizontal and vertical rollers passage in the Verschiebekulisse so that the rope can be wound cleanly on the winding coil or unwound from her.
  • the passage in the sliding backdrop leads to a variable drainage point of the rope.
  • From the EP-A-1 154 078 is a drilling device with a drilling tool, rotary and feed drives and hydraulically actuated clamping devices for fixing the drilling device to a well casing known.
  • the drilling device together with the various drives is suspended by means of a carrying cable to a boom or mast of a crane device. Since the drilling device in addition to the drilling tool also has the various drives, this is correspondingly heavy and the rope load in the supporting cable correspondingly high.
  • stinger rope lifting devices For lifting and lowering comparatively heavy tillage equipment also known as “stinger rope” lifting devices are known. These lifting devices have a supporting rope of fixed length, which can be designed in particular as a single rope. This single rope is hung, for example on a standard rope bottle, on a boom. In “stinger-rope” lifting equipment, the drilling depth is limited by the length of the boom: Especially for large drilling depths, the crane devices must be designed accordingly large because of the necessary large boom lengths.
  • the object of the invention is to provide a crane winch and a related method, which are particularly versatile at relatively high loads and in particular allow the use of comparatively little complex crane devices.
  • a crane winch has a frame, a cable suspension arranged thereon for connecting the frame to a carrying cable, a cable drum mounted on the frame for receiving a winch cable, a winch drive for driving the cable drum and a winch rope drainage device disposed on the frame below the rope suspension and defining a drainage point of the winch rope.
  • a basic idea of the invention is to provide a crane winch which can be suspended in the carrying cable of a crane device.
  • the crane winch invention must therefore not be provided in particular for direct attachment to a substructure of the crane device or on the boom.
  • the crane winch can be an independent construction, which in principle does not have to be adapted to the crane device.
  • the crane winch according to the invention can be provided both on a support cable of fixed length and on a driven suspension cable. Due to the fundamental independence of the crane winch according to the invention of the crane device carrying it crane winch invention is particularly versatile.
  • the maximum load of the crane winch can only be given by the design of the crane winch itself and its suspension and not by the maximum load of a winch possibly provided on the crane device.
  • the up and downable length and thus the drilling depth basically only by the execution of the crane winch itself, not determined by the dimensions of the crane device crane devices can particularly low boom length can be used. This may be advantageous in particular when using crane devices which are mounted on a floating body, for example a pontoon, since a small boom length leads to a slight change in the extent of the boom when the float is damaged.
  • any device can be understood, by means of which the frame is connectable to the support cable.
  • the cable suspension for direct attachment to the support cable which can be basically designed as a single rope or as a multiple rope, be educated.
  • the cable suspension can also be provided for attachment to a hook, in particular a cable bottle, which can be arranged on the supporting cable.
  • the cable suspension may have an eyelet arranged in particular in the frame for receiving the hook.
  • the cable suspension may also include one or more suspension cables extending between the support cable and the frame.
  • the winch drive according to the invention can be provided for example on the frame or in the cable drum itself. He may in particular have a motor gear.
  • the cable drum according to the invention preferably has grooves for guiding the recorded winch cable.
  • the carrying cable and / or the winch rope are suitably designed as steel cables.
  • Under a Windenseilablauf coupled invention which can also be referred to as a winding device, such a device can be understood, which leads the running into the cable drum and running from her winch rope on the frame.
  • This winch cable drainage device is preferably designed so that a tilting of the winch during the coil is largely prevented.
  • the drainage point according to the invention can be understood as meaning a point at which the winch cable leaving the crane winch is in contact with the crane winch for the last time.
  • the winch cable drainage device can determine the cable outlet point, in particular with regard to the frame, but in principle also with respect to other devices.
  • a particularly suitable for receiving high rope loads embodiment of the crane winch invention is that the cable drum is disposed between the cable suspension and the cable drain device.
  • the winch cable drainage device has at least one discharge roller which is rotatably mounted on the frame.
  • two discharge rollers are provided which have parallel axes of rotation and between which the winch cable is feasible.
  • the at least one drainage roller is suitably for guiding the Winding cables executed.
  • the cable outlet point of the winch cable can be provided on the at least one discharge roller.
  • a displacement slide is provided which is displaceable on the frame along a guide, and that the displacement slide has at least one pulley for guiding the winch rope.
  • the displacement slide with the at least one pulley can form part of the winch cable drainage device in particular. It is particularly preferred that two pulleys with parallel axes of rotation are mounted on the sliding carriage, between which the winch cable can be passed.
  • a sliding carriage with pulley may be particularly advantageous if a rotatable discharge roller is provided fixed to the frame, then the drain roller can set the expiration of the winch rope on the frame and the slidable with the carriage pulley can ensure a clean tumbling of the winch rope.
  • the pulley suitably also the displacement slide, between the cable drum and the discharge roller arranged.
  • the guide of the sliding carriage is arranged parallel to the axis of rotation of the cable drum, so that the displacement slide back and forth with the at least one pulley parallel to the axis of rotation of the cable drum.
  • the displacement slide along the guide is designed to be freely displaceable. It is particularly advantageous, however, that an actuator for displacing the sliding carriage along the guide is provided. As a result, a particularly precise tumbling of the winch rope on the cable drum can be achieved even at high rope loads.
  • the actuator is designed so that the displacement of the sliding carriage is synchronized with the rotation of the cable drum.
  • a synchronization device can be provided, which is preferably connected both to the actuator and to the winch drive.
  • the actuator may suitably comprise a drive spindle with which the sliding carriage engages.
  • the center of gravity of the crane winch is located approximately on a straight line that runs between the drain point and a point of the support rope on the crane winch, in particular on the frame.
  • the point of application of a carrying force on the crane winch and / or on the frame can be understood in particular as the point of application.
  • the center of gravity of the crane winch may also be sufficient for the center of gravity of the crane winch to lie approximately on a plane on which the point of application and the discharge point lie, wherein the plane may preferably run perpendicular to the axis of rotation of the cable drum.
  • the plane may represent a plane of symmetry of the frame, the cable drum and / or the cable drain device.
  • a device according to the invention for soil cultivation is characterized in that a crane winch according to the invention is arranged on the carrying cable.
  • a crane winch according to the invention is arranged on the carrying cable.
  • the tillage device suspended on the winch cable may in particular comprise a tilling tool, for example a drill and / or a cutting wheel, as well as a drive for the drilling tool, which may preferably be designed hydraulically.
  • an apparatus according to the invention for soil cultivation makes possible an operation in which the inclination of a jib of the crane remains substantially unchanged and the depth position of the soil cultivation device is determined solely by the crane winch.
  • the crane In principle, it is possible to provide the crane with a fixed rope for suspending the crane winch. However, it is particularly preferred that the crane has a further winch for winding and unwinding of the supporting cable with respect to the crane. This additional winch can in particular be permanently connected to the crane. To achieve particularly high loads, it may be provided that the supporting cable is reeved several times and / or that several more winches are provided. The use of another winch in addition to the crane winch invention allows a particularly fast lifting and lowering the winch rope. At the same time, the use of a further winch increases the stroke length of the device.
  • a further advantageous embodiment of the device according to the invention for soil cultivation is that the crane has a hydraulic pressure generating device for supplying the crane winch with hydraulic fluid.
  • the same hydraulic pressure generating device can also serve to supply the actuator and / or the drives of the tillage device suspended on the winch cable.
