Device for handling of ropes and use thereof

Abstract

A device is described for handling of a line that is coiled onto a rotary drum, where the line that is coiled is led through a breaking body ( 20 ) that gives a firm and approximately constant tightening in the stretch of the line towards the drum so that the coils of the line around the drum are lying sufficiently tightened. The device is characterised in that the breaking body ( 20 ) comprises breaking units ( 21,22,23 ) that offer resistance against the coiling of the drum ( 11 ) of the line, said breaking body ( 20 ) comprises a number of line guiding discs ( 21,22,23 ) via which the line is set up to be led and form a loop, said disc guide groves ( 36 ) offer said breaking effect against the hawser up to the drum ( 11 ). According to the invention, the device can be used in the handling of hawsers for anchor handling that are loosely coiled onto storage drums from the supplier, with the hawser from the storage drum being transferred into a considerably tightened state by being coiled onto a winch drum with such force that it lies compact and taut on the drum. According to another application, it is used for the tightening of wires, cables, fibrous hawsers, and the like on winch drums in connection with cranes.

         9 . A method for coiling a slack hawser onto a winch drum comprising the steps of
 providing a storage drum with a hawser coiled thereon;   providing a winding drum for coiling of the hawser from said storage drum thereon;   running the hawser in a slack condition from the storage drum to and about at least one guiding wheel located between said storage drum and said winding drum; and   conducting the hawser from the guiding wheel to and through a braking body including a plurality of hawser guiding discs, each of said discs having a guiding groove with frictional surfaces for frictionally guiding the hawser thereon, at least one of said discs including braking means for imparting a tightening creating moment on the discs to tighten the hawser conducted therearound and extending to said winding drum; and   running the hawser from said braking body to said winding drum with a tension sufficient to coil the hawser on said winding drum in successive layers without a hawser part in an outer layer of said layers sinking down between hawser parts in an underlying layer of said layers.   
     
     
         10 . A method according to  claim 9  wherein said discs are disposed relative to each other to conduct the hawser thereover with the hawser frictionally contacting about 270° of the circumferential surface of the guiding groove of each respective disc. 
     
     
         11 . A method according to  claim 10  wherein said discs number three. 
     
     
         12 . A method according to  claim 10  wherein each frictional surface of each respective disc has a coating of rubber thereon for contacting the hawser. 
     
     
         13 . A method according to  claim 10  wherein the guiding groove of each respective disc has a V-shape. 
     
     
         14 . A method according to  claim 9  further comprising the step of conducting the hawser from the braking body over a second guiding wheel to said winding drum. 
     
     
         15 . An apparatus comprising
 a winding drum for coiling of a hawser from a storage drum thereon;   at least one guiding wheel for conducting a hawser from the storage drum therearound in a slack condition; and   a braking body including a plurality of hawser guiding discs for receiving the hawser from said guiding wheel in a slack condition and conducting the hawser to said winding drum in a taut condition, each of said discs having a guiding groove with frictional surfaces for frictionally guiding the hawser thereon, at least one of said discs including braking means for imparting a tightening creating moment on said discs to tighten the hawser conducted therearound and extending to said winding drum whereby to coil the hawser on said winding drum in successive layers without a hawser part in an outer layer of said layers sinking down between hawser parts in an underlying layer of said layers.   
     
     
         16 . An apparatus according to  claim 14  wherein said discs number three and are disposed relative to each other to conduct the hawser thereover with the hawser frictionally contacting about 270° of the circumferential surface of the guiding groove of each respective disc. 
     
     
         17 . An apparatus according to  claim 14  wherein each frictional surface of each respective disc has a coating of rubber thereon for contacting the hawser and said guiding groove of each respective disc has a V-shape. 
     
     
         18 . An apparatus according to  claim 14  wherein said brake body includes a motor for rotating at least one of said guiding wheel and said discs. 
     
     
         19 . An apparatus according to  claim 14  further comprising a second guiding wheel for conducting the hawser in said taut condition from said braking body to said winding drum.
