[0055] According to the present invention, there is provided a marine foldable protective tooling, which includes a protective component 10 and a limiting component 20.

[0056] Hereinafter, the specific structures of the above components of the marine foldable protective tooling according to the present embodiment will be described.

[0057] In the present embodiment, as Figures 1 to 5 shown, the limiting component 20 is connected to the vertical rod 81 and is used to fix the protective component 10 in the unfolded or folded state. The limiting component 20 includes a connecting member 21 and a limiting member 22 respectively disposed on both side portions of the vertical rod 81, that is, the connecting member 21 and the limiting member 22 are disposed on both side portions of the vertical rod 81 facing the opening. The limiting component 20 is disposed on both side portions of the vertical rod 81 by means of connection methods such as welding or screw connection.

[0058] It should be noted that the unfolded state means that the opening on the ship deck 70 is open, and the protective tooling is in the use mode and needs to be disposed above the opening; the folded mode means that the opening on the ship deck 70 is closed and blocked by a covering, and the protective tooling does not need to be used, and it can be stored on the side wall of the fence 80.

[0059] In the present embodiment, as Figures 1 to 5As shown, the protection component 10 includes a protection member 11 for enclosing an opening and a sleeve member 12 sleeved on the outer wall of the protection member 11. The protection member 11 is preferably formed as a hollow tubular structure to reduce its own weight; the protection member 11 can be formed into structures such as a round tube or a square tube. The sleeve member 12 is preferably formed into a structure adapted to the outer wall of the protection member 11, such as a circular ring or a square ring; the protection member 11 can be deployed (set at an angle to the vertical rod 81, and in the deployed state, the protection member 11 forms a cantilever structure) or folded (set parallel to the vertical rod 81). The sleeve member 12 can slide on the outer wall of the protection member 11, and the sleeve member 12 is rotatably connected to the connecting member 21 (during the process of the protection member 11 changing from being deployed to folded or from being folded to deployed, the protection member 11 changes from horizontal to vertical, causing the sleeve member 12 to rotate 90° relative to the connecting member 21); in a preferred embodiment, the sleeve member 12 and the protection member 11 form a clearance fit, thus preventing them from being too loose and affecting the deployment effect of the protection member 11.

[0060] In order to ensure that the protection member 11 can be stably arranged above the opening in the deployed state, in this embodiment, as Figures 1 to 5 shown, in the deployed state of the protection member 11, its end can abut against the limiting member 22, so that the protection member 11 is set at an angle to the vertical rod 81 and encloses above the opening. In a preferred embodiment, the deployed protection member 11 is horizontally arranged above the opening to improve the effectiveness of the protection tooling, and the limiting member 22 can prevent the protection member 11 from overflipping and make the protection member 11 horizontally arranged.

[0061] In this embodiment, as Figures 1 to 5 shown, the connecting member 21 protrudes towards the direction where the opening is located, so that the protection member 11 can be folded on the side of the connecting member 21, thus ensuring that the protection member 11 in the folded state does not affect the overall structure of the ship, avoid causing interference, and also does not affect the aesthetics of the ship.

[0062] In order to facilitate the rotational connection between the connecting member 21 and the sleeve member 12, in this embodiment, as Figures 8 to 12 shown, a connecting portion 121 protruding towards the connecting member 21 is formed on the side wall of the sleeve member 12, and the connecting portion 121 is formed as a tubular structure; the connecting member 21 is formed with a connecting hole 211 extending towards the connecting portion 121 and penetrating through its main body. Either the inner wall of the connecting portion 121 or the connecting hole 211 is formed as a threaded hole; a fixing member 30 is used to fixedly connect the connecting hole 211 and the connecting portion 121. The outer wall of the fixing member 30 is formed with an external thread adapted to the threaded hole, and the fixing member 30 can be selected as a bolt structure.

[0063] In a preferred embodiment, as Figures 8 to 12As shown, the connecting hole 211 is formed as a threaded hole, and the fixing member 30 is screwed into the connecting hole 211 and extends to the connecting portion 121, so that the inner wall of the connecting portion 121 of the tubular structure overlaps the fixing member 30, so as to fix the positional relationship between the connecting member 21 and the sleeve member 12 to prevent the protective assembly 10 from moving downward; the limiting member 22 is preferably arranged above the connecting member 21, so that the limiting member 22 can abut against the top of the protective member 11, thereby limiting the upward displacement of the protective member 11; in this way, the protective member 11 is clamped into a horizontal expanded state.

[0064] However, the connection portion 121 may also be formed as a threaded hole, and the connection hole 211 may be formed as a smooth hole structure. The fixing member 30 passes through the connection hole 211 and forms a threaded connection with the connection portion 121 , thereby fixing the relative positions of the connection member 21 and the sleeve member 12 .

[0065] In order to form a comprehensive protection around the opening, in this embodiment, Figures 1 to 18 As shown, two groups of limit assemblies 20 are provided, and the two groups of limit assemblies 20 are respectively arranged on two vertical poles 81; the protective member 11 is formed into a bent U-shaped rod-like structure, and the opening direction of the U-shaped rod-like structure is toward the fence 80, so that the protective member 11 and the fence 80 can be arranged around the opening, and correspondingly, two sleeve members 12 are provided, and the two sleeve members 12 are respectively arranged corresponding to the two groups of limit assemblies 20, so that the connecting parts 121 on the two sleeve members 12 can be fixedly connected with the connecting hole 211, so that the force on the protective member 11 is uniform, thereby improving the stability of the protective member 11 in the unfolded state.

[0066] It should be noted that, in a preferred embodiment, the paired limiting components 20, the sleeve member 12, and the supporting member 40 and the positioning member 50 described below are mirror images in the vertical direction.

[0067] In a preferred embodiment, Figures 1 to 5 As shown, the distance between the two vertical poles 81 of the limiting assembly 20 is larger than the size of the opening, so that the opening is completely surrounded by the ring structure formed by the protective member 11 and the fence 80, thereby improving the reliability of the protective tooling.

[0068] In order to further ensure that the protection component 10 and the limiting component 20 are firmly connected in the unfolded state, in this embodiment, Figure 11 and Figure 12 As shown, the protection assembly 10 further includes a clamping member 13 disposed on the end side wall of the protection member 11, such as Figure 8 and Figure 9As shown, a threaded hole adapted to the clamping member 13 is formed at the end of the protective member 11. The penetration direction of the threaded hole is perpendicular to the length direction of the connecting portion 121. The clamping member 13 is threadedly connected to the protective member 11. The clamping member 13 is formed as a stud structure, and an outwardly protruding screwing portion 131 is formed at the head of the stud structure. The clamping member 13 can be a wing bolt.

[0069] In addition, in this embodiment, as Figure 4 and Figure 5 shown, a clamping groove 221 is provided on one side of the limiting member 22 facing away from the protruding direction of the connecting member 21. The clamping groove 221 penetrates through the main body of the limiting member 22 and the groove width is adapted to the radial dimension of the clamping member 13. In the unfolded state of the protective member 11, the side wall of the clamping member 13 extends into the clamping groove 221. The screwing portion 131 and the protective member 11 are respectively arranged at the upper and lower ends of the limiting member 22. Rotating the screwing portion 131 shortens the distance between the screwing portion 131 and the protective member 11 to firmly clamp the limiting member 22, thereby improving the connection stability between the protective member 11 and the limiting member 22, ensuring that the protective assembly 10 and the limiting assembly 20 are firmly connected, and further enabling the unfolded protective member 11 to be firmly connected to the fence 80.

[0070] In order to stably arrange the protective assembly 10 on the side of the fence 80, in this embodiment, as Figures 1 to 5 、 Figure 13 and Figure 14 shown, the marine foldable protective tooling further includes a supporting member 40 arranged on the vertical pole 81. The supporting member 40 and the vertical pole 81 can be connected by welding or screws. The supporting member 40 is arranged below the limiting assembly 20 (i.e., the supporting member 40 and the limiting assembly 20 are arranged on the same vertical pole 81). The supporting member 40 is formed with a supporting portion 41 protruding towards the protective member 11. In the folded state of the protective member 11, the end of the protective member 11 abuts against the supporting portion 41. The supporting member 40 can be formed as an L-shaped plate structure. The L-shaped plate structure forms a fold line. The supporting portion 41 and the vertical pole 81 are respectively arranged at both ends of the fold line. The supporting member 40 can be formed as a vertically arranged plate structure to increase the contact area between it and the vertical pole 81 and ensure reliable connection between the two.

[0071] In this embodiment, as Figure 6 、 Figure 7 、 Figure 13 and Figure 14 shown, the marine foldable protective tooling further includes a positioning member 50 arranged on the supporting portion 41. The positioning member 50 is formed as an annular structure for accommodating the protective member 11, so that the end of the protective member 11 in the folded state can extend into the annular structure and abut against the supporting portion 41. The positioning member 50 surrounds the outer wall of the protective member 11, enabling the protective member 11 to be stably and accurately placed on the supporting portion 41. The positioning member 50 can be formed as a circular ring or a square ring and other structures.

[0072] In order to ensure that the support member 40 and the protection member 11 are firmly connected in the folded state, in this embodiment, as Figure 6 , Figure 7 , Figure 13 and Figure 14 shown, the side wall of the positioning member 50 is provided with a positioning groove 51 extending downward from its top, and the positioning groove 51 is correspondingly arranged with the clamping member 13. In this way, without removing the clamping member 13 from the protection member 11, only the threaded side wall of the clamping member 13 needs to be exposed to extend into the positioning groove 51; in the folded state of the protection member 11, the side wall of the clamping member 13 extends into the positioning groove 51, and the protection member 11 and the screwing portion 131 are respectively arranged on the inner and outer sides of the positioning member 50. Rotating the screwing portion 131 shortens the distance between the screwing portion 131 and the protection member 11 to firmly clamp the positioning member 50, so as to firmly connect the protection member 11 and the positioning member 50, and further ensure that the protection assembly 10 and the support member 40 are firmly connected, so that the folded protection member 11 is stably arranged on the side of the fence 80.

[0073] In this embodiment, as Figures 1 to 5 shown, the fence 80 further includes a plurality of horizontally arranged crossbars 82, the limiting assembly 20 is arranged between any two adjacent crossbars 82, and the support member 40 is arranged between the ship deck 70 and the lowermost crossbar 82, so as to prevent the folded protection member 11 from protruding too high relative to the fence 80, making the protection member 11 and the fence 80 approximately form an integral body in the folded state and ensuring the aesthetics of the ship.

[0074] In this embodiment, as Figures 15 to 18 shown, the openings on the ship deck 70 include a lifting opening 61 and a passage opening 62, and a ladder is further arranged below the passage opening 62 for the staff to go up and down.

[0075] The marine foldable protection tooling according to the present invention has a simple structure, can be folded, occupies a small area, can be unfolded during work and folded up after work is completed. The protection tooling in the unfolded state can give obvious warnings to the staff, avoid safety accidents such as high-altitude falls caused by the staff stepping on the air, and guarantee the safety of the staff. In addition, the protection tooling in the folded state does not affect the overall structure and aesthetics of the ship.

[0076] A fall prevention protection method according to the second aspect of the present invention is applied to the implementation of the above marine foldable protection tooling.

[0077] In this embodiment, the fall prevention protection method includes:

[0078] When the opening on the ship's deck is in an open state, deploy the protective member; loosen the clamping member and the fixing member, pull the protective member out of the positioning member and turn it into an unfolded state, so that the end of the protective member abuts against the limiting member, and the clamping member extends into the clamping groove; slide the sleeve member to the end position of the protective member so that the connecting portion corresponds to the connecting hole; tighten the clamping member and the fixing member to complete the deployment.

[0079] After the opening on the ship's deck is closed, fold the protective member, loosen the clamping member and the fixing member; turn the protective member over and insert it into the positioning member so that the end of the protective member abuts against the supporting member, and the clamping member extends into the positioning groove; slide the sleeve member to the middle position of the protective member so that the connecting portion corresponds to the connecting hole; tighten the clamping member and the fixing member to complete the folding.

[0080] The anti-falling protection method according to the present invention is simple to operate, convenient to retract and deploy, guarantees the personal safety of the staff, reduces the incidence of accidents, thus ensuring the smooth progress of the shipbuilding work and improving the efficiency and quality of shipbuilding.

[0081] Finally, it should be noted that the above embodiments are only specific embodiments of the present application, used to illustrate the technical solutions of the present application, rather than limiting them. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: any person skilled in the art within the technical scope disclosed in the present application can still modify the technical solutions described in the foregoing embodiments or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered within the protection scope of the present application.
