[0049] As Figures 1 to 9 shown, in one embodiment, the present invention provides a ship service platform, which includes a deck 1, a support frame 2, and a plurality of connectors 3;

[0050] The deck 1 is laid on the hull frame structure 10 of the ship;

[0051] The support frame 2 has a transformer base platform frame 21 and a variable-frequency equipment base platform frame 22. The transformer base platform frame 21 and the variable-frequency equipment base platform frame 22 are arranged at the bottom of the deck 1 and support the corresponding areas on the corresponding deck 1;

[0052] The connecting member 3 is used to connect the transformer base platform frame 21 and the variable-frequency equipment base platform frame 22, and also connect the hull frame structure 10.

[0053] In this embodiment, a specific implementation manner of a ship service platform is provided. The service platform refers to various equipment maintenance operation platforms, connecting platforms, aisle platforms, etc. in areas such as the engine room, pump room, and thruster room. Angle steel or channel steel is used as the frame and legs, and diamond plate is laid on it. Generally, angle steel of L50x50 - L100x100 is used, and the area of a single piece of diamond plate does not exceed 0.8 ㎡. According to the equipment layout in the cabin, the equipment area is determined as the main load-bearing area, and the support structures in these areas need to focus on bearing the maximum equipment gravity, strength, and stability. The above-mentioned equipment has certain frequency and vibration characteristics. If a simple and thin deck structure is adopted according to the existing technology, obvious vibration of the overall deck will occur, which may further lead to hull resonance. On the other hand, the thickness of the deck 1 cannot be increased arbitrarily, which will cause the weight of the hull to increase and not meet the weight requirements. First, we first determine the area positions where the transformer base platform frame 21 and the variable-frequency equipment platform frame 22 are set. The positions of the transformer, frequency converter, braking resistor, frequency conversion cabinet, etc. are related to wire routing and the positions of other equipment, so the specific positions will be designed earlier. The support frames 2 corresponding to the area positions of these equipment are used to increase the thickness and structural strength of the deck 1. In order to improve the overall strength, through the connection between the connecting member 3 and the hull frame structure 10, the strength and stability of the hull and the ship service platform are further improved, which also conforms to the design purpose of determining the equipment area as the main load-bearing area according to the equipment layout in the cabin, and the support structures in these areas need to focus on bearing the maximum equipment gravity, strength, and stability, and helps to solve the technical problem in the existing technology that there is a lack of a technology to reduce the damage to the hull deck by some equipment and reduce the harm to the deck structure.

[0054] In one embodiment, the ship service platform further includes at least one support leg 4;

[0055] One end of the support leg 4 is connected to the support frame 2, and the other end of the support leg 4 is connected to the lower hull frame structure 10.

[0056] In this embodiment, a specific structure of the support leg 4 is provided. Since there is a space between the bottom of the deck 1 and the ship bottom, the support leg 4 can be used to support the above-mentioned support frame 2 and connecting member 3.

[0057] In one embodiment, the transformer base platform frame 21 is supported by profiles 23 at the edge, and the upper end surface 211 and the lower end surface 212 form a planar frame structure by laying planes.

[0058] In this embodiment, a specific structural implementation of the transformer base platform frame 21 is provided. The profile supports 23 are enclosed around the perimeter to form a rectangular frame structure. Thin plates are laid on the upper end face 211 and the lower end face 212 of the rectangular frame structure to form the transformer base platform frame 21. Additionally, the variable-frequency equipment base platform frame 22 also has a similar structure.

[0059] In one embodiment, equipment wiring reserved openings 213 are provided on the planar frame structure.

[0060] In this embodiment, a specific structure in which equipment wiring reserved openings 213 are provided on the planar frame structure is provided, for vertically connecting cable lines.

[0061] In one embodiment, the laying plane uses a checker plate installation grid.

[0062] In this embodiment, a specific implementation of the laying plane is provided, that is, a checker plate installation grid. On the basis of this platform frame, the outfitting section further separates it with angle steel and erects a checker plate installation frame. Finally, according to the grid layout, the sizes of the checker plates in each grid are set to fill all the gaps. The equipment placement positions are set according to the styles of the equipment bases. Support seat plates are provided at the main load-bearing points of the equipment to suspend and support the equipment, facilitating the installation of the equipment and the layout of other outfitting parts below. The entire platform design is completed.

[0063] In one embodiment, a variable-frequency cabinet, a frequency converter, and a transformer are placed in the area.

[0064] In this embodiment, a specific implementation of the area corresponding to the bearing equipment is specifically provided.

[0065] In one embodiment, the profile is provided with a reinforcing T-beam.

[0066] In this embodiment, a specific implementation of providing a T-beam on the profile is provided. In the main load-bearing area, a steel plate platform structure is set as the equipment base platform. T-beams and reinforcing ribs are added below the platform to ensure the strength of the platform. Between each equipment base platform, they are connected into one body through vertical and horizontal I-shaped steel structures and connected to the surrounding bulkheads to form a complete platform frame.

[0067] In one embodiment, the supports are arranged along the longitudinal and transverse frame spaces of the hull frame structure 10.

[0068] In this embodiment, an arrangement implementation of the supports is provided. Below the platform, legs are provided to support the entire platform. The legs also adopt the form of I-beams and are arranged according to the longitudinal and transverse frame spaces of the hull. At the positions where the legs are too high, intermediate horizontal I-shaped steel braces are added to ensure stability.

[0069] In one embodiment, the present invention further provides a ship with a ship service platform. The ship with a ship service platform includes a hull 20 and the ship service platform.

[0070] In this embodiment, a specific implementation manner of a ship with a ship service platform is provided.

[0071] Beneficial effects:

[0072] 1. For the platform plates with plate stiffeners and T-bars, the strength is guaranteed, and the bearing capacity is sufficient to meet the needs of various types of equipment.

[0073] 2. The strength of the I-beam connection structure is much higher than that of angle steel or channel steel under the same span. The entire platform surface (including the connecting angle steel) is integrated with the structure around the main hull to form a stable horizontal plane.

[0074] 3. The vertical I-beam legs have much higher strength than the densified angle steel. Through the cross braces, they are firmly connected to the ship bottom plate, avoiding instability and collapse.

[0075] In the key areas, the combination of steel plate stiffeners, steel plate T-bars and I-beams is used to replace the original angle steel or channel steel frame, improving the stability and strength of the platform structure.

The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention..
