Retraining device for a cable

Abstract

Retaining device for a cable This consists of a rotary drum ( 2 ) around which at least two cable windings are made, retaining and paying out being possible by means of a motor ( 10 ) that drives the drum. According to the present invention the axis ( 12 ) of rotation for the drive is offset with respect to the axis of the drum, so that in a certain position the axis ( 12 ) of rotation is essentially coincident with the casing face of the drum engaging on the cable.

1 . Winch system comprising a retaining device for a cable, comprising a drum for containing at least two windings of the cable on the casing face thereof, said drum being mounted on bearings such that it can rotate, wherein the distance from the casing face of said drum to the axis of rotation of said bearings varies around the periphery of said drum, said winch system comprises a cable storage having a winding/unwinding drum separate from said retaining device.  
   
   
       2 . Winch system according to  claim 1 , wherein at least one location on the periphery of the casing face is essentially coincident with the axis of rotation of said bearing.  
   
   
       3 . Winch system according to  claim 1 , wherein said casing face is circular cylindrical.  
   
   
       4 . Winch system according to  claim 1 , wherein the drum is driven by a motor.  
   
   
       5 . Winch system according to  claim 1 , wherein grooves for accommodating the cable have been made in said casing face.  
   
   
       6 . Winch system according to  claim 1 , wherein the surface of the casing face is provided with means to obtain more friction between the casing face and the cable.  
   
   
       7 . Winch system according to  claim 1 , wherein said drum is designed to accommodate a stock of cable.  
   
   
       8 . Winch system according to  claim 1  comprising braking means.  
   
   
       9 . Tug having a winch device with a winch system comprising a retaining device for a cable, comprising a drum for containing at least two windings of the cable on the casing face thereof, said drum being mounted on bearing such that it can rotate, wherein the distance from the casing face of said drum to the axis of rotation of said bearings varies around the periphery of said drum, said winch system comprising a cable storage having a winding/unwinding drum separate from said retaining device, wherein the cable release point/pick-up point with respect to said boat can be adjusted over 360° in an essentially horizontal plane.  
   
   
       10 . Tug according to  claim 9 , wherein the axis of said drum in the unloaded state is essentially vertical.
