The support rods 81 and the drive rod 82 are both straight rods, and the two support rods 81 and the drive rod 82 are arranged in a triangular shape, so that the hatch is more stable when supported on the cabin body by the hatch hinge structure 8. During assembly, one end of the two support rods 81 and the drive rod 82 can be welded to the hatch frame flange 9 respectively, and then the other ends of the two support rods 81 and the drive rod 82 can be connected to the cabin body. The frame flange 9 is an annular flange. The two support rods 81 are arranged at intervals along the circumference of the frame flange 9 and can be connected to the end face of the frame flange 9.

[0022] Specifically, the fixing rod 1, first diagonal brace 2, and fixing block 3 can be made of carbon steel, which has high rigidity. The fixing rod 1, first diagonal brace 2, and fixing block 3 can be formed separately and then connected together. A fixing rod 1, two first diagonal brace 2, and one fixing block 3 together form a triangular structure, which provides good stability. The length of the fixing rod 1 is determined by the distance between the two support rods 81.

[0023] In this embodiment, the frame flange 9 of the hatch can be connected to the cabin body through the two support rods 81 and the driving rod 82 of the hatch hinge structure 8, that is, one end of the two support rods 81 and the driving rod 82 are respectively used for welding and fixing with the frame flange 9 of the hatch; by designing an anti-deformation tooling for welding the hatch hinge structure 8, and placing the fixing rod 1 of the anti-deformation tooling for welding the hatch hinge structure between the two support rods 81, the first positioning structures 11 at both ends of the fixing rod 1 are respectively positioned and assembled with the two support rods 81 to ensure the relative position relationship between the two support rods 81, and the two ends of the fixing rod 1 are respectively connected to the fixing block 3 through two inclined rods, and the fixing block 3 is used to fix the hatch door.

This arrangement makes the force of the anti-deformation tooling for welding the hatch hinge structure more uniform and the stability better.

[0026] Optionally, the two first diagonal tie rods 2 are symmetrically arranged with respect to the second diagonal tie rod 4 .

[0027] In this embodiment, the two first diagonal braces 2 are symmetrically arranged with respect to the second diagonal brace 4, and both sides of the fixing rod 1 are subjected to uniform force, which can further improve the stability of the anti-deformation tooling for welding the hatch hinge structure and avoid welding deformation.

[0029] In this embodiment, the first straight tie rod 5 and the second straight tie rod 6 are vertically connected to form an L-shaped structure. The lengths of the first straight tie rod 5 and the second straight tie rod 6 depend on the relative position between the fixed block 3 and the fixed rod 1.

[0031] In this embodiment, two third diagonal rods 7 are provided, and one end of the third diagonal rod 7 is connected to the fixed rod 1, and the other end is connected to the end of the first straight rod 5 close to the second straight rod 6, so as to ensure the connection stability between the first straight rod 5 and the fixed rod 1, and make the force on the fixed rod 1 more uniform.

In this way, the fixed rod 1, the two first diagonal rods 2, the second diagonal rod 4, the first straight rod 5, the second straight rod 6 and the two third diagonal rods 7 can constitute a triangular pyramid-shaped anti-deformation tool for welding a hatch hinge structure. The force applied to each rod is relatively uniform and the stability is good. When the tool is used to position the hatch hinge structure 8, the positioning accuracy is high.

[0033] Optionally, the two third diagonal tie rods 7 are symmetrically arranged with respect to the first straight tie rod 5 .

[0034] In this embodiment, the two third diagonal rods 7 are symmetrically arranged about the first straight rod 5, and the two sides of the fixing rod 1 are evenly stressed, which can further improve the stability of the anti-deformation tooling for welding the hatch hinge structure and avoid welding deformation.

[0036] Specifically, the fixed rod 1 can be a quadrangular prism structure with four circumferential side walls, wherein two adjacent circumferential side walls are respectively the first side wall 12 and the second side wall 13. By fixing the first diagonal rod 2 and the second diagonal rod 4 to the first side wall 12 of the fixed rod 1, and fixing the third diagonal rod 7 and the first straight rod 5 to the second side wall 13 of the fixed rod 1, the circumferential force on the fixed rod 1 is made more uniform, thereby improving the overall stability of the tooling.

[0037] Optionally, the fixing rod 1 , the first diagonal tie rod 2 , the fixing block 3 , the second diagonal tie rod 4 , the first straight tie rod 5 , the second straight tie rod 6 and the third diagonal tie rod 7 are welded to each other.

[0038] In this embodiment, the fixed rod 1, the first diagonal rod 2, the fixed block 3, the second diagonal rod 4, the first straight rod 5, the second straight rod 6 and the third diagonal rod 7 can be formed separately and then welded and fixed to ensure the stability of the connection; during welding, a triangular cross-section weld is formed at the interface of the two rods, and the weld foot size is 8-10mm. Under the premise of ensuring that the welding is firm, there will be no material waste or welding deformation due to excessive welding. After the welding is completed, the weld quality can be tested.

The first positioning column is passed through the third positioning hole corresponding to the support rod 81 and the first positioning hole at the end of the fixing rod 1 to achieve the positioning assembly between the support rod 81 and the fixing rod 1.

[0042] Of course, in some cases, the first positioning holes at both ends of the fixing rod 1 can be connected to each other. At this time, a longer first positioning column can be used to pass through the third positioning hole on one of the support rods 81, the first positioning hole on the fixing rod 1 and the third positioning hole on the other support rod 81 in sequence, so as to realize the positioning assembly between the two support rods 81 and the fixing rod 1.

[0043] Optionally, the anti-deformation tooling for welding the hatch hinge structure further includes a second positioning column (not shown in the figure), the second positioning structure 31 is a second positioning hole, and the second positioning column is used to pass through the driving rod 82 and the second positioning hole.
