Problems solved by technology

When the hoisting object shakes suddenly and violently, the tension of the wire rope on the tension side increases sharply, which may easily cause damage to the fixed point of the wire rope on the hoisting object, and may also easily exceed the limit value of the wire rope system and cause damage to the wire rope system.

Embodiment 1

[0043]A new type of wire rope system for offshore floating cranes, including two sets of the same wire rope system for wire ropes arranged on the crane: left wire rope system and wire rope system for right wire rope, such as figure 1 As shown, the two sets of systems have the same structure, and both include a reel and its driving mechanism 101, a transition pulley 6, a well roller 102, a shackle and an anti-rotation sleeve 103, and the reel and its driving mechanism 101 are placed on the crane On the turntable under the boom or at the root of the boom, the transition pulley 6 and the well roller 102 are all installed on the boom, and the steel wire rope 4 passes through the transition pulley and the well roller after unwinding from the drum Connect the shackle and the anti-rotation sleeve, and the steel wire rope 4 leaves the arm frame through the well-tac-toe roller to connect with the hoisting object.

[0044] Wherein, the structure of well-tac-toe roller 102 is as Figur...

Abstract

The invention relates to a guy system for an offshore floating crane. The system comprises two identical guy steel wire rope systems arranged on the crane. Each guy steel wire rope system comprises areel, a driving mechanism thereof, a transition pulley, a groined shaft, a shackle and an anti-rotation sleeve, wherein the reel and the driving mechanism thereof are placed on a turntable under a cantilever crane of the crane or at the root position of the cantilever crane, the transition pulley and the groined shaft are installed on the cantilever crane, a guy steel wire rope (4) is unwound fromthe reel, penetrates through the transition pulley and the groined shaft and is connected with the shackle and the anti-rotation sleeve, and the guy steel wire rope (4) is separated from the cantilever crane through the groined shaft and is connected with a hoisted object. Compared with the prior art, the system has the characteristics of being stable in structure, long in service life, applicable to all offshore operations and the like.

Description

technical field [0001] The invention relates to a floating crane system for offshore operations, in particular to a new type of cable stabilization system for offshore floating cranes Background technique [0002] With the development of marine engineering, floating cranes have gradually developed into indispensable lifting equipment for offshore operations. Large-scale floating cranes are widely used in sea salvage, offshore pipe laying, installation and disassembly of offshore platforms, construction of offshore bridges and offshore wind power. [0003] Under the special environmental conditions of offshore operations, the action of sea waves or sea wind causes the hoisting object to shake with the sway of the ship, making the positioning of the hoisting object inaccurate or causing accidents due to large swings. Therefore, floating cranes for general offshore operations will be equipped with a cable stabilization system (such as Figure 10 ). [0004] The traditional ca...
