[0024] like Figure 1 As shown, the marine drum turning tooling includes three gantry frames 1, each of which is mainly composed of a crossbeam 7 and two legs 8; a leg 8 is provided on the bottom surface of each end of the crossbeam 7. Each gantry frame 1 is welded into a whole. After the three gantry frames 1 are arranged side by side, two arc brackets 2 are arranged on the top surface; each arc bracket 2 is mainly composed of an upper flange plate 9, a lower flange plate 11 and a web plate 10; an arc opening matching the diameter of the drum is opened on the top of the web plate 10, and the upper flange plate 9 is welded on the arc opening. The lower flange plate 11 is installed on the crossbeam 7; the arc curvature of the upper flange plate 9 is consistent with the arc curvature of the drum 6. The arc bracket 2 with the arc-shaped upper flange plate 9 is installed on the gantry frame 1 assembled by the crossbeam 7 and the legs 8, providing a stable support for the drum and making it convenient to assemble the drum.

[0025] The web 10 is welded with a stiffening plate 12, the top edge of the stiffening plate 12 is welded and fixed to the upper flange plate 9, and the bottom edge of the stiffening plate 12 is welded and fixed to the lower flange plate 11. By welding the three sides of the stiffening plate 12 to the upper flange plate 9, the web 10, and the lower flange plate 11, the structural strength of the arc bracket 2 is increased, and the working stability of the tooling is improved.

[0026] like Figure 2 As shown, fixing holes are provided on the upper end surface of the cross beam 7 and the lower flange plate 11, and the cross beam 7 and the lower flange plate 11 are installed and fixed by fixing members 13. In this embodiment, the fixing members 13 are bolts, which are convenient to obtain and easy to assemble. The bolts pass through the fixing holes on the upper end surface of the cross beam 7 and the lower flange plate 11 to connect and fix the two, and the tooling assembly is simple.

[0027] like Figure 3 As shown, one end of the angle steel 3 is welded to the crossbeam 7 of the gantry frame 1, and the other end of the angle steel 3 is welded to the stiffening plate 12 of the arc bracket 2. The gantry frame 1 and the arc bracket 2 are welded into a whole by the angle steel 3, so that the tooling is more firm.

[0028] The upper end surface of the crossbeam 7 is welded to a connecting piece of the hinge 5, and the other connecting piece of the hinge 5 is welded to the long side of the lower flange plate 11. The crossbeam 7 and the lower flange plate 11 are rotatably connected through the hinge 5. After the assembly of the roller 6 and its roller 6 bracket is completed, the welding connection at both ends of the angle steel 3 is broken. The bolt connection between the crossbeam 7 and the lower flange plate 11 is loosened. The arc bracket 2 can be turned around the hinge 5 and lie on the gantry frame 1, and then the tooling is withdrawn to realize the recycling of the tooling.

[0029] like Figure 4 As shown, the turning process of the drum 6. Four lifting ears 4 are welded on both sides of the drum body 6, of which one lifting ear 4 is welded on the driving side and three lifting ears 4 are welded on the non-driving side. When turning over, first use the three lifting ears 4 on one side of the drum 6 to lift the whole drum 6. After it is suspended in the air, release the shackle on one of the lifting ears 4 to form a natural tilt angle. Then use the lifting ear 4 on the other side, fix the shackle, and slowly lift it, and finally make the whole drum body of the drum 6 reach a horizontal state. Place the drum body 6 on the turning tool to complete the whole turning process.
