Description

Technical Field

[0001] This application relates to the field of shipbuilding technology, and in particular to a windbreak tool for welding hull plates and decks of ships. Background Technology

[0002] Welding the hull plating is a crucial step in shipbuilding. However, due to the limitations of shipbuilding sites, most shipyards or slipways are located near rivers or the sea, where there are significant monsoons for most of the year.

[0003] Excessive wind speed can severely impact the welding of hull plates. High wind speeds disperse the CO2 produced during carbon dioxide shielded welding, failing to provide effective gas protection for the weld and thus affecting weld quality.

[0004] Therefore, it is necessary to protect the welding area from wind during welding. In traditional ship hull plating welding, the tooling used has large gaps and is made of soft material, which can lead to welding spatter that can burn others and insufficient wind protection.

[0005] Regarding the aforementioned technologies, the inventors believe that traditional windproof measures are insufficient to effectively block strong winds, thus affecting the quality of welding. Summary of the Invention

[0006] In order to effectively prevent employees from being burned by welding spatter while ensuring welding quality, this application provides a windproof tooling for welding the outer plate and deck of a ship.

[0028] Welding the hull plating is a crucial step in shipbuilding. However, due to the limitations of shipbuilding sites, most shipyards or slipways are located near rivers or the sea, where there are significant monsoons for most of the year.

[0029] Excessive wind speed can severely impact the welding of hull plates. High wind speeds disperse the CO2 produced during carbon dioxide shielded welding, failing to provide effective gas protection for the weld and thus affecting weld quality.

[0030] Therefore, it is necessary to protect the welding area from wind during welding. In traditional ship hull plating welding, the tooling used has large gaps and is made of soft material, which can lead to welding spatter that can burn others and insufficient wind protection.

[0031] Regarding the aforementioned technologies, the inventors believe that traditional windproof measures are insufficient to effectively block strong winds, thus affecting the quality of welding.

[0032] In order to effectively prevent employees from being burned by welding spatter while ensuring welding quality, this application provides a windproof tooling for welding the outer plate and deck of a ship.

[0033] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a windbreak fixture for welding hull plates and decks of ships. (Refer to...) Figure 1 , Figure 2 A windproof fixture for welding the outer plate and deck of a ship includes a side enclosure 1, which is a rectangular hollow frame structure that encloses a rectangular windproof space, allowing operators to perform operations inside the windproof space.

[0037] A bottom enclosure 2 is fixedly connected to the bottom of the side enclosure 1. The bottom enclosure 2 is horizontally positioned, while the side enclosure 1 and the bottom enclosure 2 are vertically positioned. The bottom enclosure 2 can shield the bottom of the side enclosure 1 from the welding surface. Both the side enclosure 1 and the bottom enclosure 2 are made of aluminum alloy, which can withstand the high temperatures and welding spatter generated during welding, and can meet the needs of welding in multiple positions on the hull.

[0038] Multiple magnets 21 are provided on the bottom enclosure 2. A protective cover 22 is provided on the outside of the magnets 21. The protective cover 22 is a hollow shell with an opening at the bottom, and the magnets 21 are located inside the protective cover 22. The protective cover 22 is fixedly connected to the bottom enclosure 2. The limiting effect of the protective cover 22 reduces the occurrence of magnets 21 falling off when the tooling is moved.

[0039] In some embodiments, the side enclosure 1 includes two first enclosure plates 11 and two second enclosure plates 12 arranged opposite to each other. The first enclosure plates 11 and the second enclosure plates 12 are arranged sequentially along the circumferential direction, and the first enclosure plates 11 and the second enclosure plates 12 are fixedly connected.

[0040] The first enclosure 11 includes a first hinge portion 111 and a second hinge portion 112 arranged opposite to each other. The first hinge portion 111 and the second hinge portion 112 are independent plate structures. The end of the first hinge portion 111 facing away from the second hinge portion 112 is fixedly connected to the second enclosure 12, and the end of the second hinge portion 112 facing away from the first hinge portion 111 is fixedly connected to the second enclosure 12 on the other side.

[0041] The bottom enclosure 2 is also divided into two parts according to the first hinge part 111 and the second hinge part 112: the first bottom section 23 which is fixedly connected to the first hinge part 111 and the second bottom section 24 which is fixedly connected to the second hinge part 112.

[0042] In some embodiments, the first hinge portion 111 and the second hinge portion 112 are staggered along the length direction, such that the outer sidewall of the first hinge portion 111 abuts against and slides relative to the inner sidewall of the second hinge portion 112, thereby enabling the first hinge portion 111 and the second hinge portion 112 to generate a relative rotation angle, which facilitates adaptive adjustment when the welding surface is arc-shaped.

[0043] Reference Figure 1 , Figure 4 In some other embodiments, the first hinge portion 111 and the second hinge portion 112 are arranged opposite to each other, and the first hinge portion 111 is vertically provided with a hinge groove 113 on the side near the second hinge portion 112. A hinge plate 114 is fixedly connected to the second hinge portion 112 near the hinge groove 113 of the first hinge portion 111. The hinge plate 114 has an arc-shaped structure and is located inside the hinge groove 113 and is slidably connected to each other. Thus, the first hinge portion 111 and the second hinge portion 112 can generate a relative rotation angle, which facilitates adaptive adjustment when the welding surface is arc-shaped.

[0044] Reference Figure 1 , Figure 3 A first locking plate 13 is fixedly connected to the side wall of the first hinge portion 111, and a second locking plate 14 is fixedly connected to the side wall of the second hinge portion 112 at a position relative to the first locking plate 13. A first bolt hole 131 is horizontally opened on the side wall of the first locking plate 13, and the first bolt hole 131 completely penetrates the first locking plate 13. A second bolt hole 141 is opened on the side wall of the second locking plate 14. The second bolt hole 141 is an oblong hole along the height direction. The length of the second bolt hole 141 along the height direction is greater than the length of the first bolt hole 131 along the height direction. Along the horizontal direction, the horizontal projection of the first locking hole is located inside the horizontal projection of the second bolt hole 141.

[0045] Bolts are inserted into the first bolt hole 131 and the second bolt hole 141, and the other end of the bolts is fixed to the first locking plate 13 and the second locking plate 14 by a nut. When the nut is tightened, the first locking plate 13 and the second locking plate 14 are arranged in parallel. At this time, the first hinge part 111 and the second hinge part 112 are in a planar working state, which can adapt to working on a horizontal surface. When the nut is loosened, the first locking plate 13 and the second locking plate 14 have space for relative rotational displacement, which can rotate the first hinge part 111 and the second hinge part 112, so that the first bottom stop 23 at the bottom end of the first hinge part 111 and the second bottom stop 24 at the bottom end of the second hinge part 112 form a relative angle, which can adapt to working on a curved surface.

[0046] A connecting plate 115 is fixedly connected to the end of the first hinge portion 111. The connecting plate 115 is hinged to the second hinge portion 112 on the side opposite to the first hinge portion 111, so that when the first hinge portion 111 and the second hinge portion 112 rotate, they can rotate about the hinge point between the connecting plate 115 and the second hinge portion 112 as the axis, and the first hinge portion 111 and the second hinge portion 112 are connected through the connecting plate 115.

[0047] A handle is fixedly connected to the side wall of the first enclosure 11. The handle includes a first handle 15 located at the first hinge 111 and a second handle 16 located at the second hinge 112. There is space between the first handle 15 and the second handle 16 for movement.
