[0039] Figure 1This diagram illustrates the structure of the hatch cover protection fixture provided in an embodiment of the present invention. Figure 2 Show Figure 1 A magnified view of a section marked A in the middle; Figure 3 This diagram shows a partial structural schematic of the hatch cover protection fixture provided in an embodiment of the present invention. Figure 4 A schematic diagram of the internal support mechanism provided in an embodiment of the present invention is shown. (Refer to...) Figures 1-4 This embodiment provides a hatch cover protection fixture with good anti-welding deformation performance, which can effectively protect the hatch cover 10 throughout the entire shipbuilding process. The hatch cover protection fixture includes an inner support mechanism 100 and multiple locking mechanisms 200. The inner support mechanism 100 is disposed inside the hatch cover 10, and the locking mechanisms 200 provide a reliable connection between the support mechanism 100 and the hatch cover 10. In this embodiment, the hatch cover 10 is a cuboid structure with openings at both ends and a hollow interior.

[0040] Specifically, refer to Figure 3 and Figure 4 The inner support mechanism 100 includes multiple support frames spaced apart along the height direction of the hatch cover 10, each support frame including multiple support rods 110 arranged in a cross pattern. The locking mechanism 200 is detachably connected circumferentially to the wall of the hatch cover 10, and the ends of the corresponding multiple support rods 110 along the height direction of the hatch cover 10 can be connected to one of the locking mechanisms 200. In other words, the inner support mechanism 100 can reliably support the wall of the hatch cover 10 from within, ensuring the structural stability of the hatch cover 10 and effectively preventing welding deformation. The locking mechanism 200 can fix the inner support mechanism 100 to the wall of the hatch cover 10, fixing the support position of the inner support mechanism 100 and further improving the support performance of the inner support mechanism 100 on the wall of the hatch cover 10.

[0041] Reference Figure 4 The internal support mechanism 100 provided in this embodiment includes three support frames arranged at intervals along the height direction of the hatch cover 10, and each support frame includes four support rods 110 arranged in a grid pattern.

[0042] Figure 5 This diagram illustrates the structure of the locking mechanism provided in an embodiment of the present invention. Figure 1 , Figure 3 and Figure 5 The locking mechanism 200 includes a portal frame 210 and a fastener 220. The upper edge of the enclosure of the hatch cover 10 can be inserted into the portal frame 210, such as... Figure 3 As shown. The fastener 220 is screwed through the side of the portal frame 210 away from the interior space of the hatch cover 10, and the end of the fastener 220 can abut against the outside of the enclosure of the hatch cover 10.

[0043] Specifically, the fastener 220 is a bolt, and the portal frame 210 has a connecting screw hole on the side away from the interior space of the hatch cover 10. The fastener 220 is a rod-shaped structure with external threads. That is, the fastener 220 is screwed into the connecting screw hole. By rotating the fastener 220, the length of the fastener 220 within the interior space of the portal frame 210 can be adjusted until the end of the fastener 220 abuts against the outside of the enclosure of the hatch cover 10. At this point, the portal frame 210 is reliably connected to the enclosure of the hatch cover 10. In other words, the fastener 220 can fix the portal frame 210 to a suitable position on the enclosure of the hatch cover 10.

[0044] Preferably, the locking mechanism 200 further includes a pad 240. The pad 240 is disposed at the end of the fastener 220 and can abut against the outside of the hatch cover 10's enclosure. The size of the abutting surface of the pad 240 is larger than the cross-sectional size of the end of the fastener 220. In this embodiment, the pad 240 is a circular steel plate, welded or bonded to the end of the fastener 220. The pad 240 increases the contact area between the fastener 220 and the enclosure of the hatch cover 10, improving the fixation of the portal frame 210.

[0045] Preferably, there are multiple fasteners 220. In this embodiment, three fasteners 220 are provided on a portal frame 210. The three fasteners 220 are arranged at intervals along the height direction of the portal frame 210. With the above arrangement, the fixation of the portal frame 210 on the enclosure of the hatch cover 10 can be further guaranteed.

[0046] More specifically, the locking mechanism 200 also includes threaded connecting rods 230. Multiple threaded connecting rods 230 are fixedly arranged at intervals along the height direction of the portal frame 210, and the ends of multiple support rods 110 corresponding to each other in the height direction of the hatch cover 10 are also provided with multiple threaded connecting rods 230. In this embodiment, there are three threaded connecting rods 230. The end of the support rod 110 is a threaded section, and a connecting sleeve 120 is screwed onto the threaded section. The threaded connecting rod 230 can be screwed into the connecting sleeve 120 from the end away from the threaded section, thereby connecting the corresponding support rod 110 and the threaded connecting rod 230.

[0047] More specifically, in this embodiment, two locking mechanisms 200 are provided on one wall of the hatch cover 10. The number of locking mechanisms 200 is corresponding to the number of cross-arranged support rods 110.

[0048] Figure 6 This diagram illustrates the structure of the side protection mechanism provided in an embodiment of the present invention. Figures 1-3 as well as Figure 6 The hatch cover protection fixture also includes a side protection mechanism 300. This side protection mechanism 300 includes a side protection frame body 310 and a side protection connecting assembly 320. The side protection frame body 310 is detachably connected to the locking mechanism 200 via the side protection connecting assembly 320. The side protection frame body 310 extends away from the hatch cover 10. This side protection frame body 310 provides enhanced protection throughout the entire construction process of the hatch cover 10, preventing damage to the hatch cover 10 during overlapping construction work.

[0049] Specifically, the side protection frame body 310 includes a side crossbar 312 and two connecting rods 311. The side crossbars 312 are spaced apart on the wall of the hatch cover 10, and the installation height of the side crossbars 312 is higher than the upper surface of the hatch cover 10. The two connecting rods 311 are respectively connected between the side crossbars 312 and the side protection connection assembly 320. The end of the connecting rod 311 is provided with a connecting sleeve 313, which is movably sleeved on the side crossbar 312 and can be adjusted in position along the length direction of the side crossbar 312. A fastening hole is opened on the side wall of the connecting sleeve 313, and a stop bolt 314 is screwed into the fastening hole. The end of the stop bolt 314 can abut against the side of a part of the side crossbar 312 that passes through the connecting sleeve 313, thereby fixing the connecting sleeve 313 to the side crossbar 312.

[0050] More specifically, the side protection connection assembly 320 is fixed to the end of the connecting rod 311 away from the side crossbar 312, and is detachably connected to the fastener 220. (Refer to...) Figure 6 The side protection connection assembly 320 includes a first connecting frame 321 and a first rotating shaft bolt 322. The first connecting frame 321 has a gate-shaped structure, and the end of the connecting rod 311 away from the connecting sleeve 313 is fixed to the top of the first connecting frame 321. The first rotating shaft bolt 322 is rotatably connected to one end of the first connecting frame 321, and a first mounting groove 323 is provided on the other side of the first connecting frame 321. A rotating bearing seat is provided at one end of the first connecting frame 321, and a first mounting groove 323 is provided on the other side of the first connecting frame 321. The first rotating shaft bolt 322 has its rotating shaft located in the aforementioned rotating bearing seat, meaning that the first rotating shaft bolt 322 can rotate. When the first rotating shaft bolt 322 rotates and opens the bottom opening of the first connecting frame 321, the fastener 220 can enter the first connecting frame 321 through the bottom opening. Then, the first rotating shaft bolt 322 rotates and is engaged in the first engaging groove 323, sealing the bottom opening of the first connecting frame 321. At this time, the head of the fastener 220 with a larger cross-sectional area is located outside the first connecting frame 321, and the rod part of the fastener 220 with a smaller cross-sectional area is located inside the first connecting frame 321, thus achieving the connection between the side protection connecting assembly 320 and the fastener 220.

[0051] As a preferred embodiment of the hatch cover protection fixture provided by the present invention, there are multiple side protection frame bodies 310, and multiple side protection mechanisms 300 are evenly distributed on the periphery of the hatch cover 10, providing protection for the enclosure of the hatch cover 10 from multiple angles and ensuring the effectiveness of protection.

[0052] Figure 7 A schematic diagram of the fall protection mechanism provided in an embodiment of the present invention is shown. (Refer to...) Figure 5 The hatch cover protection fixture also includes a fall arrest mechanism 400. This fall arrest mechanism 400 includes a fall arrest pedal 410, which is slightly smaller than the opening size of the hatch cover 10 and is positioned above the inner support mechanism 100. The fall arrest pedal 410 prevents personnel from stepping into the hatch cover 10 and falling in, thus improving construction safety.

[0053] Specifically, the fall arrest mechanism 400 also includes a fall arrest connection assembly 420. The fall arrest connection assembly 420 is fixed to one side of the fall arrest pedal 410 and can be engaged with the support rod 110. The fall arrest connection assembly 420 includes a second connecting frame 421 and a second pivot bolt 422. The second connecting frame 421 has a door-shaped structure, and its top is fixed to the side of the fall arrest pedal 410 facing the inner support mechanism 100. The second pivot bolt 422 is rotatably connected to one side of the bottom opening of the second connecting frame 421, and a second mounting slot 423 is provided on the other side of the bottom opening of the second connecting frame 421. The second pivot bolt 422 can be rotatably engaged with the second mounting slot 423 to seal the bottom opening of the second connecting frame 421, or rotatably open the bottom opening of the second connecting frame 421 to facilitate the engagement of the support rod 110 into the second connecting frame 421.

[0054] More specifically, there are multiple fall arrestor connection components 420, and these multiple fall arrestor connection components 420 are arranged in a rectangular array on the fall arrestor pedal 410, such as... Figure 7 As shown. The aforementioned multiple fall arrestor connection components 420 can ensure the stability of the fall arrestor pedal 410 above the inner support mechanism 100, thus ensuring the fall arrest effect.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
