Problems solved by technology
[0005] When working at sea, the hull sways left and right and longitudinally under the action of wind and waves, which makes it difficult for the cables or anchor chains to be locked in the frame structure formed by the two stop pin assemblies. At this time, it is necessary to rotate and adjust the two stop pin assemblies. So that the cable or anchor chain is locked in the frame structure formed by the two stop pin assemblies, but in actual use, each stop pin assembly is usually adjusted separately, and the two stop pins cannot be adjusted at the same time, which affects the operating efficiency

The invention discloses a shark jaw device and belongs to the field of ship devices. The device comprises a box body and at least one shark jaw mechanism. Each shark jaw mechanism comprises a shark jaw assembly, a first stop pin assembly and a second stop pin assembly. The device further comprises a first rotary body, a second rotary body, a rotary oil cylinder and a connecting rod. The first stop pin assembly rotating synchronous with the first rotary body is sleeved with the first rotary body. The first rotary body is hinged to the telescopic end of the rotary oil cylinder. The rotary oil cylinder is fixedly arranged on the box body. The first rotary body and the second rotary body are connected through the connecting rod. The connecting rod is movably connected with the first rotary body and the second rotary body. The second stop pin assembly rotating synchronous with the second rotary body is sleeved with the second rotary body. By the adoption of the shark jaw device, the first stop pin assembly and the second stop pin assembly can be controlled through the rotary oil cylinder at the same time to rotate, the purpose that the two stop pin assemblies are adjusted at the same time is achieved, and the operation efficiency is improved.
Description
technical field [0001] The invention relates to the field of marine devices, in particular to a shark claw device. Background technique [0002] The shark jaw device is mainly installed on the stern deck to realize the towing operation of ships with towing functions such as three-purpose workboats, tugboats, and salvage ships, and plays an important role on commercial ships. The shark claw device usually includes a box body, two retaining pin assemblies and a shark claw assembly. The shark claw assembly and the two retaining pin assemblies cooperate with each other in practical applications to form a shark claw device. [0003] In the prior art, the shark jaws in the shark claw device are arranged behind two stop pins for clamping the cables or anchor chains. The two stop pins are combined into a door frame structure and inserted on the stern deck. To limit the swing range of the cable. [0004] In the process of realizing the present invention, the inventor finds that the...
