Description

Technical Field

[0001] The present invention relates to the technical field of suction-type catheter rack bobbin assembly, and in particular to a suction-type catheter rack bobbin longitudinal seam vertical assembly process and tooling. Background Art

[0002] As an environmentally friendly and renewable energy source, wind energy has received widespread attention and recognition worldwide. Compared to onshore wind power, offshore wind power resources are more abundant and do not occupy valuable land resources, making it more suitable for large-scale development. Precisely because of these advantages, many countries are continuously increasing their support for offshore wind power projects. In recent years, China has made significant progress in the field of offshore wind power. In 2020, the country's first suction tube jacket was successfully installed offshore, marking the birth of a new type of offshore wind power jacket structure. Suction jackets can adapt to deeper ocean environments, and as jackets move towards deep sea, they have gradually become an important development trend.

[0003] The suction-type jacket is one of the important infrastructures in the offshore wind power field, and is mainly composed of a transition section, a frame, a suction tube and other parts. Among them, the transition section section and the suction tube section are the most difficult to manufacture. Both structures are cylindrical, so the processing methods are basically the same. Taking the suction tube section as an example, the structure has the characteristics of large diameter, thin wall plate and high height. The diameter of the conventional domestic section is about 10 to 13.5 meters, the wall plate thickness is about 35 to 50 mm, and the height is about 10 to 35 meters. The processing of the cylinder structure and ensuring the roundness of the cylinder are technical difficulties. The cylinder is usually constructed by assembling sections, and each section is assembled from several sections. Under normal circumstances, the roller frame is used for binding and then welding. The specific process is as follows:

[0004] Design: According to the project design drawings and technical requirements, determine the diameter, height, wall thickness and other parameters of the cylinder, use computer-aided design software to draw the construction drawings, and carry out the layout of the cylinder.

[0005] Blanking: Cutting, processing and other blanking processes of raw materials to ensure the size and shape required for subsequent processes.

[0006] Roller frame rolling: The material is rolled using a roller frame in sections, and each section of material is welded to form a circular cylinder section.

[0007] Welding: Weld the cylinder section onto the roller frame to form a whole.

[0008] Inspection: Carry out quality inspection on the welded cylinder sections to ensure that they meet the design requirements.

[0009] The disadvantages of the above technology are as follows:

[0010] Disadvantage 1: The cylinder diameter is limited by the maximum roll diameter parameter of the roller frame equipment. The roller frame is the equipment used to build the cylinder, and its maximum roll diameter parameter limits the cylinder diameter. This means that if a cylinder with a larger diameter is required, it may be necessary to replace the roller frame equipment with a larger one, increasing the cost and complexity of the equipment.

[0011] Disadvantage 2: The cylinder's large diameter, thin cladding, and poor rigidity make it susceptible to deformation under its own weight during horizontal construction. During the construction of large cylinders, the large diameter and thin cladding can lead to insufficient rigidity, making it susceptible to deformation under its own weight during horizontal construction. This can impact construction quality and progress, requiring additional measures to ensure the cylinder's shape and accuracy.

[0012] Disadvantage 3: Correcting deformation is difficult. If deformation occurs during construction, correction can be challenging, potentially impacting construction quality and schedule. Therefore, measures must be taken during construction to prevent and control deformation, as well as effective corrective measures after deformation occurs. Summary of the Invention

[0021] Secondly, building the structure of the tooling based on the design of the tooling;

[0022] Next, after the tooling is completed, a center point sample punch mark is made with the center of the tooling as the base point, and then a circle is drawn with the center point sample punch mark as the center of the ground sample line and the designed cylinder section diameter as the diameter. This circle is the cylinder section ground sample line; then, with the cylinder section ground sample line and the designed cylinder section wall panel thickness as reference, inner and outer limit plates are arranged at intervals on the outer edge of the tooling.

[0039] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0040] Example 1

[0041] Please refer to Figures 1 to 6 As shown, a suction-type jacket rack bobbin longitudinal seam vertical assembly process includes the following steps:

[0042] S1. Design the cylinder section according to the engineering requirements and design drawings, use computer-aided design software to perform layout, and determine the dimensional parameters of the cylinder section, including the diameter, height, wall thickness and other parameters of the cylinder;

[0043] S2. Cutting, processing and other cutting processes are performed on the materials required for the cylinder section according to the design drawings;

[0044] S3. Using a rolling device, the processed material is processed into two arc-shaped plates of the same size, wherein the cross-section of the arc-shaped plates is a semicircular arc, and the two arc-shaped plates can be assembled and welded to form a cylinder segment;

[0045] S4. First, design an appropriate tooling according to the determined dimensional parameters of the cylinder section. The outer edge of the tooling is a cylindrical structure. The radius of the tooling is smaller than the radius of the designed curved plate, and the difference is between 5 cm and 50 cm.

[0046] Secondly, see Figure 2 As shown, based on the design of the tooling, the structure of the tooling is constructed using materials such as I-beams and angle steels;

[0047] Next, after the tooling is completed, a center point sample punch mark is made with the center of the tooling as the base point, and then a circle is drawn with the center point sample punch mark as the center of the ground sample line and the designed cylinder section diameter as the diameter. This circle is the cylinder section ground sample line; then, with the cylinder section ground sample line and the designed cylinder section wall panel thickness as reference, inner and outer limit plates are arranged at intervals on the outer edge of the tooling. The inner and outer limit plates are used to firmly support the arc plate therein and keep the arc plate in a vertical state;

[0048] S5. Participate Figures 3 to 6 As shown, the two arc-shaped plates are sequentially hoisted into the abutment area between the inner and outer limit plates of the tooling, and the inner and outer limit plates are used to perform detailed precision adjustments on the cylinder segment. The positions of the arc-shaped plates are adjusted so that they are connected end to end, and the joints of the two arc-shaped plates are welded to form a complete cylinder segment.

[0049] S6. Conduct quality inspection on the welded cylinder sections to ensure that they meet the design requirements.

[0050] Example 2

[0051] Reference Figures 7 and 8 As shown, a suction-type jacket rack bobbin longitudinal seam vertical assembly tool 1 includes a tool 1, an inner limit plate 3 and an outer limit plate 4;

[0052] The outer edge connecting line of the entire tooling 1 is a cylindrical structure, and the inner limit plate 3 and the outer limit plate 4 are respectively arranged on the outer wall of the tooling 1 along the circumference of the tooling 1. A circular supporting interval is formed between the inner limit plate 3 and the outer limit plate 4. The supporting interval is used to maintain the vertical state of the multiple arc plates placed therein, and the multiple arc plates are used to assemble and weld to form the cylinder section 2.

[0053] In addition, reference Figure 2 As shown, the number of inner limit plates 3 arranged at intervals around the outer wall of the tooling 1 is more than two circles, so as to ensure that the inner limit plates 3 are evenly stressed when supporting the inner wall of the arc plate. Moreover, the height of the outer limit plates 4 can be determined according to actual needs. The attached figure is only for reference, which can ensure that the arc plate will not flip outward during the support period.

[0054] Among them, one tool 1 can be applied to the design of cylinder sections 2 of various sizes. The requirement that needs to be met is that the diameter of the cylinder section 2 to be designed is larger than the diameter of the tool 1. It is only necessary to remove the existing inner and outer limit plates and redesign the spacing size of the new inner and outer limit plates to meet the design requirements of cylinder sections 2 of other sizes.

[0055] In summary, with the development of larger-scale conductor racks, the diameters of the suction cylinder and transition section cylinder are also increasing, which undoubtedly puts higher requirements on the maximum rolling diameter of the roller rack equipment. In order to meet this processing requirement, manufacturers have to constantly update their equipment, which leads to higher corporate costs. The present invention can meet the processing requirements of the cylinder with a simple tooling structure. Compared with the introduction of new equipment, the present invention can achieve the construction of large-diameter cylinders with a smaller cost investment, thereby effectively solving the problem of insufficient manufacturing capacity and reducing corporate costs. In addition, the cylinder will be deformed due to its own weight during horizontal construction. The present invention can prevent the cylinder from being deformed due to its own weight, and while ensuring the construction accuracy of the cylinder, it reduces the correction work caused by the deformation of the cylinder. In addition, the present invention is not only suitable for the construction of large conductor racks, but also for the manufacture of other large-diameter cylinders. Manufacturers can flexibly apply it according to actual needs, and it has strong applicability.
