Description

Technical Field

[0001] This utility model relates to the field of land construction of offshore wind turbine monopile foundations, and in particular to a horizontal installation tooling for the internal platform of an offshore wind turbine monopile foundation. Background Technology

[0002] In the European offshore wind power sector, monopile foundations are the most widely used foundation type for offshore wind turbines, and their technological maturity and engineering applicability have been proven through years of practice. This foundation structure not only supports the wind turbine tower but also integrates multiple functional platforms to support various equipment and operational needs. Among them, the bolt platform, inlet platform, and cable platform are responsible for fixing and supporting various components of the wind turbine.

[0003] Currently, the mainstream approach for all the aforementioned platforms is to construct them independently and then hoist them together for installation. The most common method is to use a crane and lifting lugs for vertical hoisting, lifting from the top of the platform and moving it up and down. However, since the overall size of the platform exceeds the inner diameter of the flange at the top of the monopile foundation, the platform needs to be offset as a whole before being hoisted laterally. This vertical hoisting method using cranes and lifting lugs makes it difficult to move the platform laterally and make it difficult to complete horizontal installation. Utility Model Content

[0004] To overcome the above problems, this utility model provides a horizontal installation fixture for the internal platform of an offshore wind turbine monopile foundation. The technical solution adopted by this utility model to solve its technical problems is as follows: A horizontal installation fixture for the internal platform of an offshore wind turbine monopile foundation includes a vertical support frame. Several fixed arms are provided on the left side of the vertical support frame, and each fixed arm has a connector at its end, which is connected to a telescopic boom crane. Several connecting arms are provided on the right side of the vertical support frame, and each connecting arm has a clamping component at its end, which clamps and fixes the platform to be installed.

[0005] Furthermore, the fixed arm is perpendicular to the vertical support frame, and the connecting arm is set at an angle to the vertical support frame, with the angle being greater than or equal to 15° and less than or equal to 90°.

[0006] Furthermore, the clamping assembly includes a U-shaped chuck, each with a fixing hole. Fastening screws are inserted into the fixing holes and, together with fastening nuts, are detachably and fixedly connected to the platform to be installed.

[0007] Furthermore, working platforms are installed on both the front and rear sides of the vertical support frame, and protective railings are installed on the working platforms.

[0008] Furthermore, the vertical support frame is also equipped with a vertical ladder passage, which connects to the work platform.

[0009] Furthermore, the vertical support frame is a vertical square frame structure, and the vertical ladder passage is vertically fixed inside the vertical support frame.

[0010] The beneficial effects of this utility model are: The fixture includes a vertical support frame with several fixed arms on the left side. Each fixed arm has a connector at its end, which connects to a telescopic boom crane. The right side of the vertical support frame has several connecting arms, each with a clamping assembly at its end. The clamping assembly clamps and secures the platform to be installed. In use, the fixture is first connected to the telescopic boom crane via the connectors, then the clamping assembly secures the platform. The telescopic boom crane then uses the fixture to lift the platform into position, similar to lifting a cup. The boom of the telescopic boom crane then extends and retracts to adjust the horizontal position of the platform, facilitating horizontal installation at height. Attached Figure Description

[0013] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the utility model "a horizontal installation fixture for an internal platform of an offshore wind power monopile foundation" is provided in conjunction with the accompanying drawings.

[0014] See Figure 1 and Figure 2In this embodiment, the horizontal installation fixture for the internal platform of the offshore wind power monopile foundation includes a vertical support frame 100. Four fixed arms 101 are welded and fixed on the left side of the vertical support frame 100. Each fixed arm 101 has a butt joint 102 welded and fixed at its end. The butt joint 102 can be detachably and fixedly connected to the telescopic boom crane. Several connecting arms 103 are fixedly welded on the right side of the vertical support frame 100. Each connecting arm 103 has a clamping component 104 welded and fixed at its end. The clamping component 104 can clamp and fix the platform 200 to be installed. When using this tooling, it is first installed onto the boom of the telescopic boom crane via the connector 102, and then the platform 200 to be installed is clamped and fixed via the clamping assembly 104. After that, the telescopic boom crane uses this tooling to lift the platform 200 to the installation position. This tooling allows the platform 200 to be lifted and moved like lifting a cup. Then, the telescopic boom crane extends and retracts its boom, and the tooling is used to adjust the horizontal position of the platform 200 to be installed, making it convenient and easy to achieve the horizontal installation of the platform 200.

[0015] More specifically, in this embodiment, the fixed arm 101 is perpendicular to the left side of the vertical support frame 100, so that the tooling can be easily connected and installed with the telescopic boom crane through the butt joint 102 at the end of the fixed arm 101; the connecting arm 103 is set at an angle to the vertical support frame 100, with the angle being greater than or equal to 15° and less than or equal to 90°, which facilitates clamping and fixing different shaped platforms 200 to be installed.

[0016] Furthermore, in this embodiment, the clamping assembly 104 includes a U-shaped chuck 1041, each of which is provided with a fixing hole 1042. Fastening screws are inserted into the fixing holes 1042 and, together with fastening nuts, are detachably and fixedly connected to the platform 200 to be installed.

[0017] Furthermore, in this embodiment, the vertical support frame 100 is provided with a working platform 105 on both the front and rear sides, and a protective railing 106 is provided on the working platform 105. The working platform 105 remains horizontal throughout the entire process of tooling movement, which facilitates the arrangement of personnel to move to higher places with the tooling for installation work.

[0018] More specifically, in this embodiment, the vertical support frame 100 is also provided with a vertical ladder passage 107, which connects to the work platform 105, making it convenient for workers to move between the various work platforms 105.

[0019] Furthermore, in this embodiment, the vertical support frame 100 is a vertical square frame structure, and the vertical ladder channel 107 is vertically fixed inside the vertical support frame 100 to ensure that the center of gravity of the tooling does not shift. It should also be noted that in this embodiment, the fixed arm 101 and the connecting arm 103 on the vertical support frame 100 are both located on opposite sides, and the working platform 105 on the vertical support frame 100 is also located on opposite sides. This can ensure that the center of gravity of the entire tooling does not shift to the greatest extent and improve the stability of the tooling during the lifting and moving process.
