[0002] Rigging refers to equipment used in conjunction with ropes and cables, such as hooks, tensioners, cable clamps, ferrules, shackles, etc., collectively known as rigging. In marine engineering, hooks are often needed to connect chain tools. When carrying out marine construction operations, the transported materials are basically large plates, etc., which are heavy. However, after most hooks are installed with chain tools, the position of the chain tools cannot be adjusted according to the position of the chain tools distributed inside and the area occupied, which makes it easy for the chain tools to cause greater friction inside the hook when moving materials. At the same time, the fixing structure of most hooks is relatively simple, which is easy to fall off or loosen due to external forces, which is not conducive to safe use;

[0003] There is a kind of high-strength rigging CN214087326U for marine engineering, which includes a hook, the inner surface of which is provided with a chain, the left and right sides of which are both connected with a limiting mechanism, the front of which is connected with a rotating assembly, the outer surface of which is connected with a limiting block, the surface of the limiting block overlaps the surface of the stopper, and the lower surface of the stopper is fixedly connected with the upper surface of the hook. The high-strength rigging for marine engineering, by providing a rotating assembly, a limiting block, a stopper, a spring, a sliding rod, a limiting ball, a valve and an air pipe, enables the device to lock the position of the chain to avoid large-area friction of the chain on the surface of the hook, and the device can keep the limiting block and the stopper firmly combined by elastic force to reduce the possibility of them falling off due to external force, so that the device can ensure the purpose of double safety use by locking the chain and firmly combining the limiting block and the stopper;

[0004] However, the existing device has a complex structure and numerous components during use, which is inconvenient to replace or repair. In order to solve the above problems, a lifting rigging for marine engineering construction is proposed. Utility Model Content

[0006] Furthermore, the motor and the controller are respectively located on both sides of the lower surface of the mounting plate, the connecting block is fixedly connected to the mounting plate, and the motor is controlled by the controller;

[0007] Furthermore, the connection block is fixedly connected to the hanging ring, the hanging ring is U-shaped, a blocking block is fixedly arranged at the end of the hanging ring, the pressure plate is located in the middle of the hanging ring, and the electric push rod is located on the inner wall of the hanging ring;

[0010] Beneficial effects of the utility model:

[0011] The utility model puts the chain from the blocking block into the hanging ring and places it on the pressure plate. The pressure sensor on the pressure plate transmits a signal to the controller. The controller controls the motor to drive the two electric push rods to extend, and then drives the limit plate to move inward to clamp the chain to prevent the chain from shaking.
