[0058] Finally, after completing the turning-over operation of the sheet segment 8, the first lifting device is located directly above the first lifting lug 3, and the second lifting device is located directly above the second lifting lug 5 connected therewith.​

[0059] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with specific examples as follows:

[0060] The main components of the turnover tool include thin plate segments 8, a turnover tool, bolts 10, nuts and shackles 11. The turnover tool includes first lifting lugs 3, cross beams 1, vertical beams 2, legs 7, pads 6, second lifting lugs 5, third lifting lugs 9 and vertical bases 4.

[0061] As shown in the drawings, the main structure of the turnover tool is the cross beams 1, the vertical beams 2, the legs 7 and the vertical bases 4. In order to ensure the strength of the tool, the main structure is made of a box body, including at least two cross beams 1 and two vertical beams 2 arranged vertically, the length and width of which are comparable to the segments, the legs 7 are aligned with the vertical beams 2, and 4-6 legs 7 are provided according to the size of the segments (which is the product of the number of cross beams 1 and vertical beams 2). The first lifting lugs 3 are located at the front end of the cross beams 1 and are used for lifting and hoisting during turnover. The vertical bases 4 are used for temporary storage before the turnover is positioned at 90° and the fastening of the shackles 11 for turnover operation. The cross beams 1 are provided with U-shaped grooves and reinforced structures. The second lifting lugs 5 are arranged in the U-shaped grooves in an embedded manner, and the reinforced structures are used to ensure the strength.

[0062] The third lifting lugs 9 are uniformly arranged below the thin plate segments 8, and the third lifting lugs 9 are one-to-one corresponding to the second lifting lugs 5 provided on the turnover tool. The third lifting lugs 9 are matched with the lug holes of the second lifting lugs 5 of the turnover tool, and after the second lifting lugs 5 and the third lifting lugs 9 are locked and connected, there is still a suitable gap between the thin plate segments 8 and the turnover tool.

[0063] Specifically, the thin plate segments 8 are manufactured in a reverse state, i.e., in a reverse state at the segment site, and need to be turned over by 180° during total assembly or mounting. Before turnover, temporary lifting lugs are uniformly arranged below the thin plate segments 8 to form the third lifting lugs 9. The thin plate segments 8 are moved above the turnover tool, and the third lifting lugs 9 are inserted into the lug holes of the second lifting lugs 5 corresponding to the third lifting lugs 9 on the turnover tool, respectively. As shown in the drawings, the holes of the first lifting lugs 3 and the second lifting lugs 5 need to be aligned, i.e., the first lifting lugs 3 are on the extension line of the second lifting lugs 5 on the same cross beam 1. For easy operation, the second lifting lugs 5 are provided with oblong holes. There are two embedded lug fixing methods. Shackles 11 are installed at positions that need to be coordinated with crane operation during turnover, and bolts 10 can be installed at other positions. The shackles 11 can be replaced before the turnover is positioned.

[0064] The turnover operation includes steps one, two, three and four. The turnover operation needs to be coordinated with double hooks or double cranes. After the turnover is completed, the third lifting lugs 9, the bolts 10 and the shackles 11 can be removed. For details, please refer to the drawings.

[0065] Through the technical scheme, the thin plate segmented turnover tool and the turnover operation method provided by the above-mentioned embodiments improve turnover efficiency and safety, effectively prevent deformation of the segmented plate during turnover, and have flexibility and versatility, and are suitable for turnover operation of irregular segmented plates in various placement states.

[0066] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application, and the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements are also considered to fall within the protection scope of the present application.
