Definitions

  • the invention relates to a drive device for winches and / or slewing gear for hoists with a drive motor, a differential gear connected to the drive motor, one shaft of which is operatively connected to the winch or via a pinion to the slewing gear of the hoist, and the other shaft of which a holding device is connected.
  • the purpose of the present invention is also to solve this problem, namely to raise the load without jerking at a point in time when the cable pulling force has reached the weight of the load plus any acceleration force that is currently acting.
  • this solution is to be achieved with little outlay in terms of apparatus and without a complicated control device.
  • the holding device is formed by a sheave wrapped by at least one rope and the one end of the rope is connected to a damping device which is preferably adjustable in terms of its damping behavior, for example a spring and / or piston-cylinder unit is.
  • a damping device which is preferably adjustable in terms of its damping behavior, for example a spring and / or piston-cylinder unit is.
  • a cable drum 3 is driven by a drive shaft 1 driven by a motor (not shown here) and a differential gear 2 having three shafts.
  • the third shaft 4 of the differential gear 2 is connected to a pulley 5.
  • a rope 6 is wound on the rope sheave and attached at its end to it, the other end of the cable 6 is connected to a damping element, which in the exemplary embodiment shown is designed as a piston-cylinder unit. Springs can also be used for such damping devices.
  • the damping characteristic of the damping element 7 can expediently be set so that the drive device can be adapted to different conditions.
  • the dynamic impact stress is limited to the dimension that corresponds to the setting of the damping element.
  • the drive device according to the invention is expediently used in so-called offshore cranes, but is not limited to the application.
  • dynamic impact loads of up to 150% of the load to be lifted are applied to the hoist.
  • this dynamic stress on e.g. the load to be lifted is limited to + 30%, which means that the hoist can be designed and manufactured much more easily and therefore more cheaply.
  • the reduction in dynamic stress also has a favorable effect on the load itself, which is thus protected from damage.
  • the drive device works independently of switching intervention by the operating personnel.
  • the pulley 5 is connected to a rope 6 and an attenuator. If the drive device is used in connection with a slewing gear, two ropes with opposing winding senses are applied to the sheave 5, both ends of which are connected to a damping device 7, so that in this case dynamic shock loads are absorbed and damped in both directions of rotation of the slewing gear can be.
