Abstract
Description
Technical Field
[0001] The utility model relates to an adjustable supporting beam for turning over steel pipe piles of jacket platforms. Background Art
[0002] In recent years, the offshore wind power industry in China has developed rapidly. It is in large-scale construction from south to north, and the wind farm locations are gradually developing from nearshore to deep sea. Therefore, affected by different marine hydrological conditions and geology, the scales of offshore substation jacket platforms vary, and the diameters of their supporting steel pipe piles are also different.
[0003] Such as Figure 1 shown, in the existing construction of offshore jacket steel pipe piles, a floating crane single hook is generally used in cooperation with two wire rope loops for main hanging and buckling. To ensure the smooth turning over of the steel pipe piles, it is necessary to adjust the piles to be parallel to the main lifting wire rope for turning over through a supporting beam, that is, the steel pipe piles are in a vertical state.
[0004] The diameters of the jacket steel pipe piles in each project are different. Before construction, it is necessary to separately process a supporting beam device suitable for turning over the jacket steel pipe piles of this project. Therefore, there are disadvantages such as a long processing cycle of the supporting beam, inability to be recycled, and high construction cost. Therefore, in view of the above problems, an adjustable supporting beam for turning over jacket steel pipe piles is proposed. Content of the Utility Model
[0005] The purpose of the utility model is to provide an adjustable supporting beam for turning over jacket steel pipe piles to overcome the existing defects, which can be applicable to the turning over construction of jacket steel pipe piles with different diameters.
[0006] The technical solution for realizing the above purpose is: an adjustable supporting beam for turning over jacket steel pipe piles, comprising a seamless steel pipe and supporting components connected to both ends of the seamless steel pipe;
[0007] The supporting components include a pin shaft, an ear plate, a support plate and a shackle; the ear plate and the support plate are connected to the side wall of the end of the seamless steel pipe, and the pin shaft is connected to the ear plate; the shackle is connected to the circular side wall of the seamless steel pipe.
[0008] Preferably, there are two ear plates, which are respectively located on both sides of the end of the seamless steel pipe. Concentric holes are provided on the two ear plates, and the pin shaft is connected in the concentric holes.
[0009] Preferably, the support plate is located between the two ear plates.
[0010] Preferably, the support plate is V-shaped.
[0011] Preferably, the support plate is welded to the seamless steel pipe and the ear plate.
[0012] The beneficial effects of the present utility model are as follows: The adjustable support beam for turning over the steel pipe piles of the jacket has the advantages of being applicable to turning over steel pipe piles of jackets with different diameters compared with the original fixed-condition support beam. It can be transformed using the original support beam, shortening the processing cycle and enabling early construction on site; it is applicable to multiple working conditions, no longer being single, and can be recycled; transforming using the original support beam has a low transformation cost and high economic applicability.

[0018] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. In the description of the present utility model, it should be noted that the orientation or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and should not be construed as indicating or implying relative importance.
[0019] The present utility model will be further described below in conjunction with the accompanying drawings.
[0020] As Figures 2 - 4 shown, an adjustable support beam for turning over the steel pipe piles of the jacket includes a seamless steel pipe 4 and support components connected to both ends of the seamless steel pipe 4; the support components include a pin shaft 1, an ear plate 2, a support plate 3, and a shackle 5; the ear plate 2 and the support plate 3 are connected to the end side walls of the seamless steel pipe 4, and the pin shaft 1 is connected to the ear plate 2; the shackle 5 is connected to the circular side wall of the seamless steel pipe 4. There are two ear plates 2, which are respectively located on both sides of the end of the seamless steel pipe 4. Concentric holes are provided on the two ear plates 2, and the pin shaft 1 is connected in the concentric holes. The support plate 3 is located between the two ear plates 2. The support plate 3 is V-shaped. The support plate 3 is welded to the seamless steel pipe 4 and the ear plate 2.
[0021] As Figure 3 shown, during on-site hoisting operations, one end of the auxiliary wire rope 6 is hung on the hook of the floating crane's lifting ship, and the other end is connected to the supporting beam through a shackle 5; the main hoisting wire rope of the steel pipe pile is passed through both ends of the supporting beam and then hung on the hook of the floating crane's lifting ship. There are two operating conditions for the supporting beam. When the main hoisting wire rope directly acts on the pin shaft 1, it can be applied to the 2.7m jacket steel pipe pile; when the pin shaft 1 is removed and the main hoisting wire rope directly acts on the support plate 3, it can be applied to the 2.5m jacket steel pipe pile. Therefore, by removing the pin shaft 1 on-site, the supporting beam structure can be adapted to the turning-over of 2.5m to 2.7m jacket steel pipe piles.
[0022] This adjustable supporting beam for the turning-over of the jacket steel pipe pile has the advantages of being applicable to the turning-over of jacket steel pipe piles with different diameters compared with the original fixed-condition supporting beam. It can be transformed using the original supporting beam, shortening the processing cycle and enabling early construction on-site; it can be applied to multiple working conditions, no longer being single, and can be recycled; using the original supporting beam for transformation has a low transformation cost and high economic applicability.
