Description

Technical Field

[0001] The present invention relates to the technical field of ship assembly, and in particular to a hull module guiding and positioning structure and method. Background Art

[0002] The hull usually adopts a modular design and is divided into multiple prefabricated modules, such as cabins, decks, and sides, which are convenient for production, inspection, and assembly in the factory. During production, the hull modules are usually made of steel, aluminum alloy, or composite materials. The finished hull modules are completed as a whole in the slideway area and directly lifted onto the main hull of the project using a large floating crane. In order to ensure the smooth lifting of the modules, the hull module assembly needs to be positioned.

[0003] In the prior art, for example, the patent with publication number CN102180229B discloses a detachable modular ship and a connection method of its hull modules. Above the main deck, it includes two modules, namely, a cab and an operating instrument operating room synthesis module, and an air compressor integrated container module. Below the main deck, it includes a left living water supply and drainage system module at the bow, a right living room module, a left main engine, a gear box, a tail shaft, a propeller propulsion system and a rudder system module at the stern, and six detachable modules, namely, a right main engine gear box, a tail shaft, a propeller propulsion system and a rudder system module. The six modules are connected to each other longitudinally and transversely through connecting blocks between longitudinal and transverse bulkhead plates and decks and bottom plates to form a whole.

[0004] The above structure divides the hull into several modules, which are then assembled into an integral ship after arriving at the destination. During the assembly process, when a floating crane is used for lifting, it is difficult to guide the hull modules, resulting in poor accuracy of the docking position between the modules and a long service life of the floating crane. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose a hull module guiding and positioning structure and method to solve the problem that when using a floating crane for lifting, the guidance between hull modules is relatively difficult, resulting in poor docking position accuracy between modules and long use time of the floating crane.

[0006] Based on the above purpose, the present invention provides a hull module guiding and positioning structure and method, including a main hull and a deck module, wherein a plurality of keel frames are arranged inside the main hull, a plurality of structural beams are arranged inside the deck module, a plurality of positioning members are arranged between the keel frames and the structural beams, and the plurality of positioning members are respectively arranged on both side edges and inside of the main hull and the deck module;

[0007] The positioning member includes a load-bearing column, a top column is fixedly installed on the top of the load-bearing column, and the top column is clamped between two groups of adjacent structural beams. A reinforcing plate is fixedly installed on one side of the load-bearing column, and a pad is fixedly installed on the bottom of the load-bearing column. Side panels are evenly distributed outside the pad, and the tops of multiple groups of side panels are fixedly installed on the outside of the load-bearing column, and the side panels and the keel frame are clamped together.

[0008] Preferably, the multiple groups of keel frames are arranged in a cross shape, and the multiple groups of structural beams are arranged in a staggered shape.

[0009] Preferably, the side panel comprises a plurality of groups of positioning plates fixedly mounted on the outside of the bearing columns, outer sides of the plurality of groups of positioning plates are fixedly mounted with peripheral plates, and inner sides of the positioning plates are fixedly mounted with inner lining plates.

[0013] Keel installation: First install the keel frame on the main hull to ensure the horizontal and vertical position of the main load-bearing structure of the main hull. Prepare welding materials, connectors and positioning parts according to the keel frame design drawings of the main hull;

[0014] Deck module installation: After the main hull bottom structure is assembled, the internal structure of the deck module is installed. According to the structural design requirements of the drawings, the structural beams are installed in the deck module frame to ensure the horizontal and vertical position of the main structure. After completion, the hull module is guided and positioned;

[0015] Guided positioning: In accordance with the structural design requirements of the drawings, three sets of positioning points are set on the edges and inside of the deck module and the main hull, and marked. The positioning pieces are determined according to the positioning points. The bearing columns and top columns in the positioning pieces are first clamped into the structural beams in the deck module. The deck module is directly hoisted by the floating crane and moved toward the main hull.

[0016] Welding connection: According to the setting of three groups of positioning points, when the three-point fixed module is guided to the main hull, the inner plate of the positioning piece smoothly clamps the positioning point part of the main hull to ensure the smooth lifting of the module, keep the docking position between the modules accurate, ensure that all the joints of the modules are aligned, cut off the side plate below the pad, and check the docking angle and position of the welding joint, and use the welding process to weld the modules together to ensure the firmness of the structure;

[0017] Leveling and correction: After completing the guiding and positioning assembly of the main hull and deck modules, overall leveling and correction are carried out to ensure that the shape of the hull is consistent with the design requirements, and then a comprehensive inspection is carried out on the welding quality, structural stability and sealing to ensure the assembly quality.

[0018] Preferably, during the welding connection, reinforcing ribs and other components are added when necessary to ensure the load-bearing capacity and stability of the hull.
