[0002] To meet the diverse functional needs of ships and future upgrades, modular, removable structures and devices are increasingly being used on various types of vessels. To achieve their functionality, these devices typically require rigid mounting to the hull and transfer their loads to the structure. To address this, traditional structures and devices are either welded directly to the hull or mounted on a pedestal welded to the hull, making installation and removal unsuitable for modularity.

[0003] Mooring holes are a commonly used ship mooring facility, usually buried in the hull deck. They can be used to tie down movable equipment and cargo on the ship, freeing them from deck space after they are removed. However, their mooring effect can only limit the displacement of equipment and cargo relative to the hull to an acceptable range, and cannot completely limit the displacement and thus transfer loads. Therefore, how to achieve a rigid connection between a detachable structure or device and the mooring hole while facilitating the disassembly and assembly of the detachable structure or device has become an urgent problem to be solved. Summary of the Invention

[0009] Further, the bolt limiting block is internally provided with a threaded hole matched with the mounting bolt of the detachable structure or device.

[0010] Further, a groove is formed at the opening of the threaded hole on the bolt limiting block to limit the rotation of the bolt head of the mounting bolt.

[0011] Preferably, the expansion locking assembly comprises a cross mounting block, an expansion block, a compression block and an expansion bolt, the cross mounting block is arranged at the lower part of the center of the mooring hole to limit a plurality of bolt limiting blocks, the expansion bolt is arranged at the upper part of the center of the mooring hole and is threadedly connected with the cross mounting block, the expansion block is correspondingly arranged with a plurality of bolt limiting blocks and is uniformly arranged in the circumferential direction of the expansion bolt, and the compression block is arranged between the expansion block and the expansion bolt and is compressed against the expansion block when the expansion bolt is tightened.

[0012] Further, the compression block is a conical block or a wedge-shaped block.

[0013] Further, the side of the expansion block facing the expansion bolt is a conical surface or an inclined surface matched with the compression block.

[0014] Further, the cross mounting block has a "+" shape in cross section, and a threaded hole is arranged at the center of the cross mounting block to mount the expansion bolt.

[0015] Further, the bolt limiting block and the expansion block are arranged in four, and the four expansion blocks are combined to have a "+" shape.
