Description

Technical Field

[0001] The invention relates to the technical field of offshore cranes, and in particular to an offshore crane with a windproof and high-stability structure. Background Art

[0002] Offshore crane is a kind of lifting equipment specially used in marine engineering. It has a large lifting capacity and working radius, which is convenient for various lifting operations. The stability of offshore crane is effectively controlled by setting the installation platform structure and lifting ship parts. When the lifting equipment used by offshore crane is in use, the stability of lifting is controlled by setting different lifting equipment to prevent the sea breeze from affecting its lifting.

[0003] The windproof and high-stability structure used in offshore cranes can effectively control the stability of hoisted objects and the safety of offshore cranes according to the usage conditions through the installed hoisting equipment;

[0004] During use, it is inconvenient to control the stability of the sling, which affects the safety of the device. It is easy to cause the high-hanging materials to tilt, and it is easy to cause the lifting sling to tilt and cause the goods to fall off;

[0005] In order to overcome the above-mentioned defects, the prior art (Chinese patent with application number CN202411230391.6 and application date 2024-09-04) is a high-stability bottom-supporting suspended offshore crane, which uses a suspension hook to lift the cargo body, and then lifts the cargo body to a high place by winding the main lifting rope through a winch, and at the same time, the telescopic cylinder contracts and uses the second guide wheel at its top to pull the auxiliary pull rope, so that the auxiliary pull rope lifts the bottom support plate upward, supports the bottom of the cargo body, reduces the overall force of the suspension hook, and the bottom support plate can stabilize the cargo body to prevent it from loosening; further, the auxiliary pull rope uses friction to drive the first guide wheel to rotate during the tightening process, so that the first guide wheel drives the active bevel gear to rotate synchronously, and at this time, the driven bevel gear meshing with the active bevel gear drives the transmission screw to rotate, and under the action of the transmission screw, the positioning plate installed with threads passing through its outside moves to the middle position, thereby pushing the cargo body to the middle position to prevent its center of gravity from shifting;

[0006] There is also prior art (Chinese patent with application number CN202223553543.5 and application date 2022-12-28) a pulley assembly, a lifting mechanism and a crane, which can be selectively connected to the first bracket or the second bracket through the fourth pulley block. When the crane is working, the ratio of the pulley assembly can be selected according to the actual working conditions. For example, when the lifting weight is large, the fourth pulley block is connected to the second bracket. At this time, the rope hoists the second bracket through the third pulley block and the fourth pulley block. Since the rope is wound around the fourth pulley block, the second pulley block, the first pulley block and the third pulley block, the pulley assembly can have a larger ratio. When the lifting weight is small, the fourth pulley block is connected to the first bracket. At this time, the rope hoists the second bracket through the third pulley block. Since the rope is wound around the fourth pulley block, the second pulley block, the first pulley block and the third pulley block, the pulley assembly has a smaller ratio.

[0007] And the prior art (Chinese patent with application number CN201921157621.5 and application date 2019-07-22) self-decoupling lifting row for cargo transfer, which can realize the connection between the cargo lifting assembly and the cargo bag by passing the two slings of the cargo lifting assembly through a cargo bag respectively and then connecting them with the hook during operation, and then connecting the lifting assembly to the lifting equipment, and starting the lifting equipment to lift the cargo bag for transfer of the cargo bag. Since multiple groups of cargo lifting assemblies are arranged longitudinally on the upper edge of the lifting beam assembly, each group of cargo lifting assemblies can lift two cargo bags at the same time, so the self-decoupling lifting row can lift multiple cargo bags at a time, thereby greatly increasing the number of cargo transferred in a single time and effectively improving the transfer efficiency; after the cargo bag is transferred to the designated position, the driving assembly drives the rotating longitudinal beam to rotate, which can drive the hook to rotate accordingly, so that the hook is disengaged from the sling, and automatic decoupling is achieved, thereby realizing automatic unloading, thereby reducing manual operation links and further improving the transfer efficiency;

[0008] Although the existing technology can be hoisted and adjusted, it is not convenient to independently control the stability of the hoisting rope during operation, and it is not convenient to independently control the stability of the top positioning device, and it is not convenient to adjust the stability of the hoisting device connection, and in windy weather, the bottom plate will shake too much.
