Driving device driving determines that pulling block is determined around the space point radius of gyration, then by guy rope driving device around this point and radius angle of rotation
Degree, so that it is determined that the spatial position of pulling block.Load-carrying pulley: pass through guy rope driving device, cable drive device, load-carrying rope driving dress
Common driving is set, its vertical position is determined by reeling for load-carrying rope driving device.Load-carrying pulley is with pulling block identical vertical
On direction.
The utility model has the advantages that compared with prior art
1, it can inhibit loads along boom direction and perpendicular to the shaking in boom direction.Maritime environment is usually changeable and answers
It is miscellaneous, and traditional anti-shake mode can only inhibit loads along the shaking in boom direction, by load-carrying rope acting device and wing-shaped
The spatial position of two guy rope acting device co- controlling pulling blocks on support frame, reduces loads shaking amplitude quickly, from
And it reduces complicated sea situation bring and lifts by crane difficulty.
2, high frequency, inhibit to shake to high dynamic response.Traditional anti-shake mode inhibits the reaction shaken slower, and relies on actively
The mode of control can be realized high-frequency, high dynamic response loads be inhibited to shake.
3, load is big, lifting spatial domain is wide.Lifting loads is increased by the double-slider structure of pulling block and load-carrying pulley
The biggest lifting capacity, load become much larger.Under some more complex lifting environment, lifting space becomes relatively narrower sometimes, by
It is changeable in the traction angle of rope, it will lead to rope and wipe and encounter cargo or container, and the design separated using pulling block with suspension hook,
Make the triangle that the angled rope in part is constituted on pulling block to control the horizontal position of weight, is controlled by the rope of part under pulling block
The position of weight vertical direction processed keeps pulling block higher in lifting by adjusting the speed of related movement of load-carrying rope and drag-line
Position can solve the problems, such as that narrow lifting space exists.
