Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine installation equipment, and in particular to a wind turbine tower installation equipment. Background Art

[0002] As a clean and renewable energy acquisition method, wind power generation has been rapidly developed and widely applied globally. As an important part of wind power projects, the research and optimization of wind turbine installation equipment are particularly important.

[0003] Currently, during the construction and installation of wind turbines, large hoisting machinery is mainly used to hoist each part of the wind turbine into place one by one. However, with the continuous progress of wind power technology, the single-unit capacity of wind turbines is increasing continuously, and the installation height is also rising continuously. This poses higher requirements for hoisting machinery, including higher load-bearing capacity and higher technical requirements for hoisting workers.

[0004] Traditional hoisting machinery is difficult to meet the installation requirements of existing wind turbines, and the equipment rental cost is expensive. Therefore, a new wind turbine tower installation equipment and construction method are urgently needed to be studied. Summary of the Invention

[0011] As a preferred solution, 8 load-bearing support mechanisms are arranged around the installation position.

[0037] 1. The tower barrel tray of the present invention can move back and forth, left and right on the loading platform, making the installation of the tower barrel more accurate.

[0038] 2.

[0039] 3. The present invention can remove the wind turbine tower barrel by slightly modifying the reverse operation of the installation steps, with reasonable design.

[0040] Note: The hoisting and tower barrel connection involved in the present invention are all prior arts and will not be elaborated here. Description of the Drawings

[0052] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the invention, then the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly. In addition, "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0053] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0054] As shown in the figure, a wind turbine tower barrel installation device includes a load-bearing support mechanism 2, a shrinking mechanism 3, a load-carrying lifting platform 4, and a tower barrel conveying platform 5. The load-bearing support mechanism 2 is arranged around the installation position, and the installation position is used to connect the tower barrel 1. The shrinking mechanism 3 is installed on the top of the load-bearing support mechanism 2.

[0055] As a preferred embodiment, the tower barrel 1 includes three support rings, namely, an upper support ring, a middle support ring, and a lower support ring.

[0056] As a preferred embodiment, eight load-bearing support mechanisms 2 are arranged around the installation position. Among them, six load-bearing support mechanisms 2 are evenly divided into two groups and are respectively evenly distributed in two adjacent 120° regions around the installation position. The remaining two load-bearing support mechanisms 2 are arranged in the remaining 120° region, and there is an opening between the two load-bearing support mechanisms 2. The tower barrel tray 43 can slide from the opening to the tower barrel transfer platform 5.

Then, the pressing block 3234 presses the first telescopic arm 321 to realize the fixed length of the contraction mechanism 32.
