Description

Technical Field

[0001] The utility model relates to the field of power generation tower transportation, in particular to a marine tooling for wind power towers. Background Art

[0002] As a clean and renewable energy power generation method, wind power generation has been increasingly welcomed and valued by people around the world. At the same time, wind power generation is one of the most mature and large-scale development conditions in new energy power generation technologies. Therefore, in recent years, the wind power generation industry around the world has been booming, and the iteration rate of domestic wind turbines is also getting faster and faster, increasing from a diameter of 5 - 6 meters to 8 - 8.5 meters. In order to obtain better wind resources, the height of the wind turbines has also increased to more than 120 meters, and domestic wind turbine products are gradually expanding overseas markets.

[0003] When transporting large wind power products at home and abroad, large cargo ships are usually selected. The tower barrels can be stored in both the cargo hold and on the deck. If placed in a single layer according to the ordinary method of transporting tower barrels, even if two additional decks are added in the cargo hold, a large amount of space in the height direction will still be wasted in the cargo hold, and only one layer can be placed on the deck. Therefore, a tooling that can transport in double layers has been developed to achieve placing twice the amount of tower barrels on the deck of the cargo ship with the same area.

[0004] In the prior art, a marine equipment for double - layer stacking of offshore wind power towers with an application date of October 12, 2022 and an application number of CN202211248674.4 was disclosed. The inventor believes that the existing such marine equipment has the following defects:

[0005] 1. The upper equipment main body and the lower equipment main body are connected by fasteners through fixed pressing plates with mounting holes welded to the columns. The anti - overturning strength of this connection method is insufficient and may break during sea transportation;

[0006] 2. The ladder is set at the central position on the front of the upper equipment main body and the lower equipment main body. This design interferes with the installation of the tower flange and is not easy to operate;

[0007] 3. Docking and installation are required between the upper equipment main body and the lower equipment main body, and the difficulty of hole position docking is large, and the installation difficulty is high.

[0008] Based on this, the present application provides a marine tooling for wind power towers with reliable connection between the upper tooling and the lower tooling, high anti - overturning strength, and convenient docking and installation. Utility Model Content

[0036] Embodiment 1

[0037] This embodiment provides a marine transportation tooling for a wind power tower barrel. As shown in the attached drawings Figure 1 It includes a lower tooling 1 for fixing the lower tower barrel and an upper tooling 2 for fixing the upper tower barrel. The upper tooling 2 is detachably connected to the lower tooling 1; both the upper tooling 2 and the lower tooling 1 are composed of two toolings fixedly installed at both ends of the tower barrel; the lower tooling 1 is in an H shape, including two columns and multiple connecting beams arranged between the two columns. On the side facing the tower barrel, concentric arc-shaped connecting plates 1.1 are welded at its top and bottom respectively. Connection holes 1.1.0 for connecting with the flange of the tower barrel are provided on the arc-shaped connecting plates 1.1, and the flange of the tower barrel is connected to the arc-shaped connecting plate through fasteners; arc-shaped connecting plates 2.1 for connecting with the flange of the tower barrel are also provided on the upper tooling 2, and the arc-shaped connecting plates 2.1 are welded to the two columns of the upper tooling 2.

[0038] The connection method between the upper tooling and the lower tooling in this embodiment is as follows: As shown in the attached drawings Figure 2 to the attached drawings Figure 6As shown, crossbeams 3 connecting the two columns are respectively welded to the top end of the lower tooling 1 and the bottom end of the upper tooling 2. End plates 4 are welded to the top ends of the columns of the lower tooling 1 and the bottom ends of the columns of the upper tooling 2, and are welded to the crossbeams 3. The end plates 4 and the crossbeams 3 are on the same horizontal plane. Multiple bolt holes 3.1 are provided on the flange plates of the crossbeams 3 for fixing between the upper tooling 2 and the lower tooling 1. This design enables the upper tooling and the lower tooling to be fixedly connected by using fasteners through the crossbeams, with a large connection area and high connection reliability, improving the anti-overturning strength of the upper tooling.

[0039] Further, as shown in Figure 2 , Figure 3 and Figure 5 shown, positioning pins 5 are provided on the end plates 4 of the lower tooling 1, and positioning holes 4.1 inserted with the positioning pins 5 are provided on the end plates 4 of the upper tooling 2. This design enables the lower tooling and the upper tooling to be inserted and positioned through the positioning pins and the positioning holes. After being aligned and placed, the bolt hole positions on the crossbeams of the two are aligned, and fasteners can be directly installed without repeatedly adjusting the position during hoisting.

[0040] Embodiment 2

[0041] On the basis of Embodiment 1, as shown in Figure 1 to Figure 6 shown, the columns and the crossbeams 3 in this embodiment are made of I-beams, and the bolt holes 3.1 are provided on the flange plates of the crossbeams 3.

[0042] Preferably, as shown in Figure 2 , Figure 3 , Figure 5 and Figure 7 shown, a slot 5.1 inserted with the web on the column of the upper tooling 2 is provided in the middle of the positioning pin 5, and a guiding groove 5.2 is provided at the top of the slot 5.1. The guiding groove has an automatic alignment function. When the positioning pin passes through the positioning hole, the web of the upper tooling falls into the guiding groove and is automatically aligned under the action of the guiding groove as the upper tooling is lowered.

[0043] In the above embodiments, as shown in Figure 1 to Figure 3 shown, a ladder 6 is further provided on the side of the column of the lower tooling 1, and both ends of the ladder 6 are fixedly installed on the flange plates of the column. This design does not interfere with the installation of the tower barrel and the arc-shaped connecting plate, reducing the installation difficulty.

[0044] In the above embodiments, as shown in Figure 1 to Figure 3 shown, a standing foot 7 is also welded to the bottom end of the column of the lower tooling 1 for stably placing the tooling on the deck.

[0045] In the above embodiments, as shown in the appended Figure 1 to the appended Figure 6 figures, a plurality of lugs 8 are welded on the columns of the upper tooling 2 and the lower tooling 1, including a plurality of lugs welded on the front of the column and a plurality of lugs welded on the side of the column. This design can tighten the tooling to the deck through steel wires, and can also tighten the tooling to form an integral whole.

[0046] During specific implementation, first install the lower tooling on the tower barrel. After hoisting the tower barrel to the set position on the deck, use steel wires to tighten the tooling to ensure the position of the lower tower barrel is fixed; then install the upper tooling on the tower barrel, hoist the tower barrel above the lower tooling, lower it after aligning the positioning holes with the positioning pins of the lower tooling, and install the fasteners of the cross beam to connect the upper tooling and the lower tooling into one body, and then tighten the upper tooling on the deck through steel wires.

[0047] After installing multiple columns of tower barrels, tighten the adjacent two columns of tooling through steel wires to form a stable integral whole.
