Description

Technical field:

[0001] The present invention relates to the field of design of a pile fixing frame structure for a lifting platform, and in particular to a pile fixing frame structure for a self-elevating platform and a wind power installation platform thereof. Background technology:

[0002] In the "CCS Rules for Classification of Offshore Mobile Units 2020 Edition", the second part 1.2.1.7 freeboard deck is defined as: the highest open-air full-length deck of the platform, all open-air openings on it are equipped with permanent closing devices, and all external openings below it are equipped with permanent watertight closing devices. 1.2.1.8 bulkhead deck is defined as: the continuous deck reached by each watertight transverse bulkhead. In the "CCS Rules for Classification of Steel Seagoing Ships 2021 Edition", the second part 1.1.2.6 upper continuous deck is defined as: the highest full-length deck of the hull.

[0003] However, in some ships or offshore platforms with special structures, the design of this full-length deck does not meet the structural requirements of the design, especially in large ships or offshore platform equipment similar to wind power platforms, which have a pile foot structure. The design of this type of structure will form a different load mode from the overall structure of the offshore platform equipment, so the continuous deck design in the prior art will have problems.

[0004] There is an urgent need for a self-elevating platform pile frame structure, which helps to solve the technical problem that there is a lack of a continuous deck applicable to a ship or offshore platform with a pile frame in the prior art. Summary of the invention:

[0008] At least one longitudinal side bulkhead is longitudinally arranged along the edge of the vacant area, so that the deck of the pile fixing frame area is connected to the edge of the vacant area and is isolated by the longitudinal side bulkhead.

[0009] In one embodiment, a main structural longitudinal bulkhead is provided at the bottom of the main deck, and the main structural longitudinal bulkhead is a continuous deck.

[0010] In one embodiment, the main deck welding edge and the main structure longitudinal bulkhead are provided with flashes, and the distance between the flashes is greater than 100 mm.

[0039] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0040] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to determine the true intent based on the user's historical operations and to avoid unnecessary or redundant details that make the present application unclear.

[0043] like Figures 1 to 6 As shown, in one embodiment, the present invention provides a self-elevating platform pile frame structure, the self-elevating platform pile frame structure includes a pile frame area deck 1 and a main deck 2, and at least one longitudinal side bulkhead 3;

[0044] The main deck 2 has a vacant area 21 connected to the deck 1 in the pile frame area;

[0045] The longitudinal side bulkhead 3 is longitudinally arranged along the edge 31 of the vacant area 21 , so that the pile frame area deck 1 is connected to the edge 31 of the vacant area 21 and is isolated by the longitudinal side bulkhead 3 .

[0046] In this embodiment, a specific implementation of a pile frame structure of a self-elevating platform is provided. The pile frame is used to provide support for the upper and lower sliding tracks, which is also the biggest difference between this type of equipment and other equipment that can apply a continuous deck. In order to ensure that the stress of the pile frame is in a good state, it helps to solve the technical problem in the prior art that there is a lack of a continuous deck that can be used on ships or offshore platforms with pile frames.

[0047] Specifically, Figure 1 The continuous deck in the multi-layer deck is a continuous deck design. If we simply understand the continuous deck as a horizontal horizontal plate, then the wall plate is a longitudinal support plate. The so-called continuous deck is a continuous horizontal plate structure that can be welded together by multiple plates, but the whole is not broken and needs to be continuously spliced. Figure 2 The connection between the connecting deck and the pile frame includes three parts. The first part is the connecting member between the pile frame and the platform, the surrounding well structure, and the connection between the continuous deck and the pile frame. Generally, welding is used for connection. However, we found that the moving parts of the pile frame move in the up and down direction, while the strength of the continuous deck is guaranteed in the horizontal direction, so stress concentration will occur. Due to the huge force of the moving parts, this stress will eventually easily cause the weld of the deck to crack. Therefore, similar to the prior art, Figure 1 and Figure 2 situations such as Figure 3As shown, in the present invention, the design of the continuous deck is abandoned, and the longitudinal side bulkhead 3 located near the pile frame is ensured to be able to extend out of the main deck 2. In this way, the movement of the moving parts is in the same direction as the longitudinal side bulkhead 3, so it will not affect the main deck, at least it will greatly reduce the impact on the horizontal up and down stress, thereby avoiding stress concentration on the main deck 2.

[0048] In one embodiment, a main structural longitudinal bulkhead 22 is disposed at the bottom of the main deck 2, and the main structural longitudinal bulkhead 22 is a continuous deck.

[0049] In this embodiment, a specific implementation method is provided in which a continuous deck is adopted in addition to the pile frame area and the deck 1 area. In order to ensure the overall structure of the ship, in addition to the pile frame area and the deck 1 area, the design principle of a continuous deck should be maintained as much as possible.

[0050] In one embodiment, the welding edge 31 of the main deck 2 and the main structure longitudinal bulkhead 22 are provided with a flash 23, and the distance between the flash 23 is greater than 100 mm.

[0051] In this embodiment, a flash 23 is provided to overlap and weld with the main structure longitudinal bulkhead 22 to ensure that stress is not concentrated. The continuous part and the discontinuous part are overlapped by the flash 23 to ensure the boundary and strength.

[0052] In one embodiment, a bracket 32 ​​is provided on the top of the longitudinal side bulkhead 3 .

[0053] In this embodiment, a specific implementation method is provided for reinforcing the structure of the longitudinal side bulkhead 3 by means of a bracket 32. The bracket 32 ​​is designed as an integral structure with the longitudinal side bulkhead 3, so as to further enhance the strength in the longitudinal direction and ensure that the moving parts will not cause stress release of the deck and eventually cause cracking.

[0054] In one embodiment, the self-elevating platform pile fixing frame structure includes a pile fixing frame 4;

[0055] The pile fixing frame 4 comprises an upper pile fixing frame 41 and a lower pile fixing frame 42 , and the lower pile fixing frame 42 is embedded in the section of the surrounding well 5 .

[0056] In this embodiment, a pile fixing frame 4 is provided which is an assembly structure of two parts, namely an upper pile fixing frame 41 and a lower pile fixing frame 42. The upper and lower parts are divided into.

[0057] In one embodiment, the distance between the closing opening of the upper pile frame 41 and the lower pile frame 42 and the main deck 2 is 835 mm.

[0058] In this embodiment, a distance between the closing opening of the upper pile frame 41 and the lower pile frame 42 and the main deck 2 is provided to ensure the strength of the overall structure. This design is also to prevent stress concentration, so a predetermined distance is constructed between the closing opening and the main deck 2, and the predetermined distance should be greater than 835 mm.

[0059] In one embodiment, a plurality of supporting structures 12 are disposed at the bottom of the deck 1 in the pile fixing frame area.

[0060] In this embodiment, a specific implementation method is provided for supporting the deck 1 in the pile frame area by multiple support structures 12. A plurality of support structures 12 are arranged at the bottom of the deck 1 in the pile frame area, and the longitudinal wall supports of the support structures 12 are arranged in a staggered manner to provide the deck 1 in the pile frame area with good support force and rigidity.

[0061] In one embodiment, the present invention further provides a wind power installation platform using a self-elevating platform pile frame structure, wherein the wind power installation platform includes the self-elevating platform pile frame structure.

[0062] In this embodiment, a specific implementation of a wind power installation platform using a self-elevating platform fixed pile frame structure is provided. The wind power installation platform has three sets of pile leg structures, and the support of the platform is achieved by the up and down movement of the pile legs, that is, the moving parts. During the up and down movement of the pile legs, the guide rail parts fixed thereto and the connection structure with the platform hull need to be reconstructed through the above-mentioned discontinuous deck method.
