Description

Technical Field

[0001] This invention relates to a base for a fully rotating crane vessel, belonging to the field of ship design and manufacturing technology. Background Technology

[0002] Existing crane vessel bases are generally single-base designs, concentrating loads from multiple directions onto a single base. Furthermore, existing crane vessels typically employ a full-rotation design. When the crane vessel rocks, the base must withstand not only significant static operating loads but also substantial inertial dynamic loads. This places extremely high demands on the vessel's structural strength, resulting in exceptionally high manufacturing costs. Simultaneously, it poses significant safety hazards, potentially leading to capsizing and severely impacting the safe operation of the crane vessel. Therefore, this technical field urgently needs to address the problem of the excessive load borne by a single base on current crane vessels, which affects safe operation. Summary of the Invention

[0003] The purpose of this invention is to solve the technical problem that existing crane vessels have a large load on a single base, which affects safe operation.

[0004] To achieve the goal of solving the above problems, the technical solution adopted by the present invention is to provide a base for a fully rotating crane vessel, including a main beam base that provides support for the main beam and an auxiliary beam base that provides support for the auxiliary beam. The main beam is provided on the main beam base, and the auxiliary beam base is provided on the outside of the main beam base. The auxiliary beam base is provided with a truss-shaped auxiliary beam. The outer frame and internal truss of the auxiliary beam are fitted onto the main beam.

[0005] Preferably, the main beam is perpendicular to the main deck.

[0006] Preferably, the main beam is in the form of a truss.

[0007] Preferably, auxiliary beam bases are provided on both symmetrical sides of the main beam base; a rotating shaft passing through the main beam is provided on the auxiliary beam bases on both sides.

[0008] Preferably, the two ends of the rotating shaft are provided with fixing rods for connecting the auxiliary beam; the fixing rods are perpendicular to the rotating shaft.

[0009] Preferably, the horizontal cross-section of the main beam is a rectangular outer frame, which includes the long side and the short side of the main beam.

[0010] Preferably, the cross-section of the auxiliary beam perpendicular to the axis of the auxiliary beam is a rectangular outer frame, which includes the long side and the short side of the auxiliary beam.

[0011] Preferably, the long side of the main beam and the short side of the auxiliary beam are on the same side, and the short side of the main beam and the long side of the auxiliary beam are on the same side.

[0012] Preferably, the short side of the auxiliary beam and / or the internal truss of the auxiliary beam abuts against the long side of the main beam; the plane containing the short side of the auxiliary beam is parallel to the plane containing the long side of the main beam.

[0013] Preferably, the long side of the auxiliary beam and / or the internal truss of the auxiliary beam abuts against the short side of the main beam; the plane containing the long side of the auxiliary beam is parallel to the plane containing the short side of the main beam.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The crane vessel and its lifting method provided by this invention, through the double-base design of the main beam and auxiliary beam, improve the strength of the main beam on the one hand, and enable the auxiliary beam and the main beam to resist the crane load together on the other hand; at the same time, there are independent reinforcing structures under the main beam base and the auxiliary beam base, which is more conducive to the structural reinforcement design and greatly improves the safety of operation.

[0020] To make the present invention more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings:

[0021] like Figure 1-3As shown, the technical solution adopted by the present invention is to provide a base for a fully rotating crane vessel, including a main beam base 4 supporting a main beam 1 and an auxiliary beam base 3 supporting an auxiliary beam 2. The main beam 1 is mounted on the main beam base 4, and the auxiliary beam base 3 is located on the outer side of the main beam base 4. The auxiliary beam 2 is mounted on the auxiliary beam base 3 in the form of a truss. The outer frame and internal truss of the auxiliary beam 2 are fitted onto the main beam 1. The main beam 1 is perpendicular to the main deck 5; the main beam 1 is in the form of a truss; the auxiliary beam base 3 is located on both symmetrical sides of the main beam base 4; a rotating shaft 32 passing through the main beam 1 is mounted on the auxiliary beam base 3 on both sides. Fixing rods 31 for connecting the auxiliary beam 2 are provided at both ends of the rotating shaft 32; the fixing rods 31 are perpendicular to the rotating shaft 32. The horizontal cross-section of the main beam 1 is a rectangular outer frame, which includes the long side 6 and the short side 7 of the main beam. The auxiliary beam 2, perpendicular to its axial direction, has a rectangular outer frame, comprising the long side 8 and the short side 9 of the auxiliary beam. The long side 6 of the main beam and the short side 9 of the auxiliary beam are on the same side, as are the short side 7 of the main beam and the long side 8 of the auxiliary beam. The short side 9 of the auxiliary beam and / or the internal truss of the auxiliary beam abuts against the long side 6 of the main beam. The long side 8 of the auxiliary beam and / or the internal truss of the auxiliary beam abuts against the short side 7 of the main beam. The rectangular outer frame of the auxiliary beam 2 fits over the outer side of the rectangular outer frame of the main beam 1, abutting against the main beam 1.

[0022] like Figure 1 The image shows a two-way view of the crane vessel base, which includes a main crane beam 1, an auxiliary crane beam 2, an auxiliary beam base 3, a main beam base 4, and a main crane vessel deck 5. The main beam base 4 supports the main beam 1, and the auxiliary beam base 3 supports the auxiliary beam 2.

[0023] like Figure 2 The diagram shows an auxiliary beam 2 and an auxiliary beam base 3, including the auxiliary beam 2, a fixing rod 31, and a drive shaft 32.

[0024] like Figure 3 The diagram shows a schematic of the main beam 1 and the main beam base 4, including the main beam 1 and the main beam base 4. Since the main beam 1 has high requirements for structural strength, the hinged structure is set as few times as possible.

[0025] Except for the axial load along the main beam 1, the auxiliary beam 2 can bear the load in other directions, which can be distributed to the main beam 1. At the same time, the main beam 1 and the auxiliary beam 2 do not share the same reinforcement structure, which is conducive to the separate design of the reinforcement structure under the base. The main beam 1 is a structure fixed on the main beam base. Since the main beam is not overturned, the hinge support mechanism is eliminated, thus improving the strength of the main beam.

[0026] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any form or substance. It should be noted that those skilled in the art can make various improvements and additions without departing from the present invention, and these improvements and additions should also be considered within the scope of protection of the present invention. Any modifications, alterations, and equivalent changes made by those skilled in the art based on the above-disclosed technical content without departing from the spirit and scope of the present invention are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the scope of the technical solution of the present invention.
