Description

Technical Field

[0001] This utility model relates to the field of engineering construction structure technology, specifically to a novel auxiliary tooling for welding scissor braces. Background Technology

[0002] Offshore wind power has become an important area of ​​renewable energy development in recent years. During construction, the offshore wind turbine jacket is a crucial component of an offshore wind farm, primarily used to support and secure the wind turbine generators. It serves as the connection between the underwater pile foundations and the upper tower of the wind turbine. It is mainly used in offshore wind farms with large single-unit capacities, deep water levels, and challenging geological conditions. The jacket supports the weight of the wind turbine, substation, or upper structure, transfers loads from the seabed, and ensures stability in strong winds, rough seas, and corrosive seawater. Structurally, it requires excellent sealing, structural stability, and high strength.

[0003] In the prior art, as shown in Chinese patent application CN 119102247 A, the technical solution described is a jacket foundation and a jacket foundation construction method. The jacket structure includes a main frame and a support structure. The support structure includes multiple support rod groups arranged along the height direction. The support rod groups are connected to the first connecting parts of the two side legs. The first connecting parts have a first grouting space filled with grout. The legs also include two second connecting parts, which are respectively located on the top and bottom connecting sections. The support rod groups also include a third connecting part and two cross-arranged support members. The ends of the support members are connected to the first or second connecting parts. The two support members are connected through the third connecting part, which has a third grouting space filled with grout.

[0004] Under this structure, the installation structure between the first connecting part, the second connecting part, and the third connecting part located in the center cannot guarantee that the scissor brace is located in the center of the jacket, and there are multiple levels of scissor braces in a jacket depending on the position. This state is limited by factors such as welding construction, pipe precision, and manual labor, and obviously cannot guarantee the structural consistency of the jacket. Utility Model Content

[0005] Therefore, this utility model provides a novel auxiliary tooling for welding scissor braces, which solves the problem of insufficient consistency of scissor braces in existing guide frames.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A scissor brace welding auxiliary tooling includes a bracket assembly, the bracket assembly including two rectangular brackets, at least two connecting beams connecting the two rectangular brackets, and several support plates disposed on the rectangular brackets for supporting each pipe.

[0008] The two connecting beams extend from one side edge of a rectangular bracket to one side edge of another rectangular bracket, and are fixed together after being staggered from each other, forming a straight connecting edge and a staggered edge with a broken line; during welding, the center of the scissor brace structure is located at the center of symmetry of the staggered edge.

[0009] Preferably, the support plate is a vertical plate with an arc-shaped surface at the top, and the vertical plate is welded to each rectangular bracket.

[0010] Preferably, the support plate consists of a vertical plate with an arc-shaped top surface and triangular structural plates on both sides of the vertical plate.

[0011] Preferably, the support plate comprises two bottom beams, a crossbeam connecting the two bottom beams, a column located at the connection between the crossbeam and the two bottom beams, a top beam located at both ends of the two columns, and a vertical plate with an arc-shaped top surface arranged on the bottom beam.

[0012] Preferably, vertical reinforcing plates are provided on both sides of the upright plate.

[0013] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0014] This technical solution addresses the external dimensions of the jacket framework by designing a bracket assembly that facilitates positioning and planning of each section's dimensions. The dimensions of each section are adjusted and positioned using this bracket assembly, ensuring that the dimensions of each section meet design requirements. This facilitates welding construction, guarantees consistent welding of the scissor braces, and features a simple structure that is conducive to production. Furthermore, the bracket assembly can be configured in two different shapes to accommodate the production of jacket frameworks of varying sizes, offering high flexibility.

[0023] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Example

[0024] refer to Figures 1 to 7 A welding auxiliary method for scissor bracing involves dividing the outer dimensions of the guide frame from bottom to top into a lower section 1, a middle section, and an upper section 3. The middle section is further divided into a lower-middle section and an upper-middle section 2. Corresponding lower surface 1a, lower-middle surface, upper-middle surface 2a, and upper surface 3a on the guide frame are defined. Each of these surfaces is an isosceles trapezoid with decreasing area. The construction process includes the following steps:

[0025] S1, Welding the lower section of the frame 1:

[0026] Within the area of ​​section 1a (the largest dimension of the lower frame 1), the ends of the welded pipes are cut and shaped, and each pipe is placed in an "X" shape, with the centers of each pipe interconnected. Each pipe is supported by several support plates 4. The support plate 4 structure consists of two bottom beams 41, a crossbeam 42 connecting the two bottom beams 41, a column 43 located at the connection between the crossbeam 42 and the two bottom beams 41, a top beam 44 located at both ends of the two columns 43, and an upright plate 45 with an arc-shaped top surface arranged on the bottom beams 41. Vertical reinforcing plates 46 are provided on both sides of the upright plate 45. This support plate 4 structure has sufficient structural strength for the largest dimension of the lower frame 1, and the number can be flexibly selected according to the size of the lower frame 1 for flexible use.

[0027] S2, Welding of the middle section frame:

[0028] The welding of the lower and middle sections of the frame and the welding of the upper and middle sections of the frame are carried out separately. The two ends of the welded pipes are cut and shaped, and each pipe is placed in an "X" shape with the center of each pipe interconnected. Each pipe is positioned by a bracket assembly 5.

[0029] The bracket assembly 5 includes two rectangular brackets 51, two connecting beams 52 connecting the two rectangular brackets 51, and several support plates 4 disposed on the rectangular brackets 51 for supporting each pipe; wherein, the cross section of the connecting beams 52 is I-shaped, which can ensure the structural stability of the connection between the connecting beams 52 and the rectangular brackets 51, and also ensure the external structure of the bracket assembly 5.

[0030] Among them, the upper and middle section of the frame 2 is relatively small in size, and the bracket assembly 5 used has the following connection structure:

[0031] Type a, the two ends of the two connecting beams 52 are respectively fixed to the two ends of one side edge of the two rectangular brackets 51, so that the two rectangular brackets 51 are arranged in parallel on the same horizontal plane to form a rectangular structure. When the pipe is welded, the middle section is located at the center of the rectangular structure; (the upper and lower edges of the upper middle section 2a slightly extend beyond the edge of the bracket assembly 5).

[0032] The lower section of the frame 1 is relatively large, and the connection structure of the bracket assembly 5 used is as follows:

[0033] Type b, the two connecting beams 52 extend from one side edge of a rectangular bracket 51 to one side edge of another rectangular bracket 51, and are fixed together after being staggered from each other, forming a straight connecting edge 53 and a staggered edge 54 with a broken line; when the pipe is welded, the center of the middle section is located at the center of symmetry of the staggered edge 54.

[0034] In this way, during production, type A and type B bracket assemblies 5 can be selected according to different sizes. Since the dimensions of the rectangular bracket 51 and connecting beam 52 of the bracket assembly 5 are clear, the structural dimensions of the produced middle section frame can be easily determined, which is more conducive to production.

[0035] S3, Welding the upper frame section 3:

[0036] The size of the upper section 3 is further reduced compared to the middle and upper section 2. Therefore, a type a bracket assembly 5 of the same size as in step S2 is used, limited to the upper section surface 3a (the upper section surface 3a is entirely within the range of the two bracket assemblies 5). The ends of the welded pipes are cut and shaped, and each pipe is placed in an "X" shape, with the centers of each pipe interconnected. When the pipes are welded, the upper section surface 3a is located at the center of the rectangular structure. This technical solution designs a bracket assembly 5 for easy positioning and planning of the dimensions of each section of the jacket frame, based on the external dimensions of the jacket frame. The dimensions of each section of the jacket frame are adjusted and positioned by the dimensions of the bracket assembly 5, ensuring that the dimensions of each section of the jacket frame meet the design requirements, which is beneficial for workers to weld and ensures the welding consistency of each section of the scissor brace. The structure is simple and conducive to production. The bracket assembly 5 can be modified into two different shapes according to the dimensions of the jacket frame to be suitable for the production of jacket frames of different sizes, which is highly flexible.

[0037] During construction, steps S1, S2, and S3 can be performed separately. Furthermore, during the welding of each pipe section, tie rods 6 are installed for auxiliary support. This further ensures that the welded sections of the frame are at the same level and provides auxiliary support during the welding process, preventing displacement.

[0038] Structurally, in steps S1, S2, and S3 above, each pipe has a triangular reinforcing plate 7 located between the pipes and distributed horizontally, as well as a longitudinal reinforcing plate 8 connecting at least two pipes at the welding connection position. The triangular reinforcing plate 7 ensures that the angle of the "X" shaped structure is maintained, while the longitudinal reinforcing plate 8 is located at the upper and lower ends of the pipes, further improving the strength of the connection structure.

[0039] In actual production, the structure of the support plate 4 can be flexibly selected according to requirements, simplifying the support plate 4 as follows:

[0040] ① It is a vertical plate with an arc-shaped surface at the top;

[0041] ② The supporting plate 4 is composed of a vertical plate 45 with an arc-shaped surface at the top and triangular structural plates on both sides of the vertical plate 45.

[0042] This makes it easier to fix the support plate 4 onto the rectangular bracket 51, facilitating construction.

[0043] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
