SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough of existence among the prior art, providing an vice winding system cross hinge device that plays to rise, prevent to play to rise the emergence of the wire rope condition of jumping the groove, realize playing to rise the horizontal beat by a wide margin of wiring device, adapt to the unrestrained hoist and mount environment of marine strong wind more.

According to the technical scheme provided by the utility model, the auxiliary hoisting and winding system cross hinge device comprises a fixed pulley block and a guide pulley block, a movable pulley block matched with the fixed pulley block is arranged below the fixed pulley block, a steel wire rope clockwise and alternately bypasses the fixed pulleys and the movable pulleys on the fixed pulley block and the movable pulley block, the fixed pulley block is hung below the guide pulley block through a hanger, a pair of guide pulleys parallel to each other is arranged on the guide pulley block, a group of fixed pulley blocks are arranged under each guide pulley, a diverting pulley coaxial with the fixed pulleys is arranged on the fixed pulley block, a driven pulley at one end of the steel wire rope passes through the diverting pulley and then bypasses the corresponding guide pulley and finally is wound on the periphery of a winch to form a starting end, the other end of the steel wire rope passes through the fixed pulley far away from the diverting pulley on the fixed pulley block and extends to the other fixed pulley block to form, the pulley axis on the fixed pulley block is perpendicular to the pulley axis of the guide pulley above, the pulley axis on the fixed pulley block is parallel to the pulley axis of the movable pulley below, and the pulley axis plane of the fixed pulley block is parallel to the pulley axis of the guide pulley above.

Compared with the prior art, the beneficial effects of the utility model are that: the device can be used for assisting a main lifting pile-turning hoisting, the hoisting weight can transversely swing by 30 degrees to the maximum, a steel wire rope cannot have the danger of groove separation, the structure is compact, the occupied space is small, the device is convenient to arrange on an arm support, and the device can adapt to various use occasions needing transverse 30 degrees of swing to the maximum.

The utility model discloses a difference with prior art lies in, the utility model discloses a pulley shaft of a pair of fixed pulley group is parallel to each other for the epaxial fixed pulley one-to-one of a pair of pulley, adjacent fixed pulley is located the coplanar, wire rope and fixed pulley chute wall plane that link to each other between two fixed pulley groups do not have the contained angle, therefore wire rope is stable when the lifting hook is horizontal beat is located the spout of fixed pulley, be difficult for taking off the groove, and among the prior art, wire rope that links to each other between the fixed pulley group passes through the pinch roller and impresses in the spout, wire rope has the contained angle with the chute wall plane of fixed pulley, hold in the palm the risk that the groove still has when.
