[0033] When welding, grinding and painting the side of the ship 10, operators are usually required to climb up to perform the work. In the prior art, operators generally need to build scaffolding to perform the work. The traditional scaffolding is troublesome to build and dismantle, inefficient, and has poor protection effect and poor safety, and there are safety hazards such as falling from a height.

[0034] To this end, this embodiment provides a side cage that can meet the support platform requirements for welding, grinding, painting and other works on the side of the hull 10, and is easy to assemble and disassemble, safe and reliable, and has a significant effect on shortening the shipbuilding cycle.

[0035] Specifically, Figures 1 to 3 As shown, the side hoist cage provided in this embodiment includes a ladder body 1, an anti-slip hook 2, a protective cage 3 and an anti-fall plate 5. The anti-slip hook 2 is fixedly connected to the top of the ladder body 1. A groove 21 is provided in the anti-slip hook 2. The anti-slip hook 2 can be hooked on the top of the side 10 of the hull through the groove 21. The protective cage 3 is fixedly connected to the ladder body 1 and together with the ladder body 1 forms an operating space 4. The anti-fall plate 5 is fixed to the bottom of the ladder body 1 and is located in the operating space 4.

[0036] When in use, the entire side hanging cage can be directly hooked on the top of the side 10 of the hull through the groove 21 of the anti-drop hook 2. It is easy to assemble and disassemble, and the construction workers can stand on the ladder body 1 and work in the operating space 4. Among them, the ladder body 1 is used for construction workers to climb and stand to work, and the protective cage 3 is fixedly connected to the ladder body 1 to protect the safety of the construction workers. It is used in conjunction with the anti-fall plate 5 at the bottom of the ladder body 1. When the construction workers accidentally fall from the ladder body 1, the protective cage 3 is used for protection of the surrounding side, and the anti-fall plate 5 can provide a standing position for the construction workers, thereby preventing the construction workers from falling from a high altitude. It can be seen that the side hanging cage is easy to assemble and disassemble, safe and reliable, can ensure the personal safety of construction workers, is convenient for welding, grinding, and painting of the side 10 of the hull, can speed up construction efficiency, and has a significant effect on shortening the shipbuilding cycle.

[0037] Specifically, Figure 1 As shown, the ladder body 1 includes two parallel and spaced longitudinal beams 11 and a plurality of cross beams 12 welded between the two longitudinal beams 11. The plurality of cross beams 12 are evenly and spaced along the length direction of the longitudinal beams 11, and the anti-drop hooks 2 are welded to the longitudinal beams 11. The cross beams 12 are used for workers to climb and stand. In order to ensure the structural strength of the ladder body 1, the longitudinal beams 11 and the cross beams 12 can be selected as angle steel or round steel pipes. The specific number of the cross beams 12 is not specifically limited here, and can be flexibly set according to actual needs.

[0038] In this embodiment, two anti-slip hooks 2 are provided on one side of the top of the ladder body 1, and the two anti-slip hooks 2 are respectively welded to the corresponding longitudinal beams 11, and the two anti-slip hooks 2 can be hooked on the top of the hull side 10 at the same time. By setting two anti-slip hooks 2 to be hooked on the hull side 10 at the same time, the force balance of the ladder body 1 can be ensured, no deflection occurs, and the connection is stable, ensuring stability and safety during operation. In other optional embodiments, the number of anti-slip hooks 2 can also be set to three, four or more evenly arranged along the width direction of the ladder body 1, which can be flexibly set according to actual needs, and no specific limitation is made here.

[0039] Furthermore, combined with Figure 2 and Figure 3 The protective cage 3 is a steel frame structure extending in the longitudinal direction, specifically including a plurality of surrounding beams 31 spaced apart in the longitudinal direction and at least two connecting beams 32 extending in the longitudinal direction, the plurality of surrounding beams 31 are connected to the ladder body 1, specifically, the two free ends of the surrounding beams 31 are welded and fixed to the longitudinal beams 11 on both sides, so as to form the above-mentioned operation space 4, and at least two connecting beams 32 are fixedly connected to the plurality of surrounding beams 31. The surrounding beams 31 can be used as safety guardrails, mainly for protection, and the connecting beams 32 are used to connect the surrounding beams 31 together, mainly for reinforcement, so as to Figure 1 From the front view, the surrounding beams 31 and the cross beams 12 are arranged alternately.

[0040] Among them, the surrounding beam 31 and the connecting beam 32 can be selected as angle steels, and the two are fixed together by welding, so that the structure is stable and firm, and the protection effect is improved.

[0041] In this embodiment, if Figure 2 and Figure 3 As shown, the number of the surrounding beams 31 can be six, and the six surrounding beams 31 are evenly spaced in the longitudinal direction, and the number of the connecting beams 32 can be three, and the three connecting beams 32 are evenly and spaced in the axial direction of the surrounding beams 31, and each connecting beam 32 is fixedly connected to the six surrounding beams 31 at the same time, so as to form a stable and firm protection cage 3. In other optional embodiments, the number of the surrounding beams 31 and the connecting beams 32 is not limited thereto, and can be adaptively set to other numbers according to actual conditions, and no specific limitation is made here.

[0042] In this embodiment, if Figure 3 As shown, the surrounding beam 31 can be selected to be an arc shape. The operating space 4 enclosed by the surrounding beam 31 of this shape is large enough, and compared with the square surrounding beam 31, less material is used, and it is easier to achieve the weight reduction effect. Of course, in other optional embodiments, the surrounding beam 31 can also be selected to be square, so that the enclosed operating space 4 is a rectangular parallelepiped.

[0043] Furthermore, in this embodiment, combined with Figure 2 and Figure 3 The anti-fall plate 5 includes a plate body 51, two first support beams 52 and three second support beams 53. The extension direction of the first support beam 52 is parallel to the thickness direction of the ladder body 1, and the extension direction of the second support beam 53 is parallel to the extension direction of the cross beam 12. The two first support beams 52 are arranged in parallel and at intervals along the extension direction of the cross beam 12, and are fixedly connected to the longitudinal beam 11 on the corresponding side of the ladder body 1. The three second support beams 53 are welded in parallel and at intervals between the two first support beams 52, thereby forming a stable and firm support frame. The plate body 51 covers and is welded to the support frame formed by splicing the first support beam 52 and the second support beam 53, thereby forming a stable and firm integrated anti-fall plate 5, which can play an effective anti-fall role. In order to ensure the overall structural strength of the anti-fall plate 5, the first support beam 52 and the second support beam 53 can be angle steels, and the plate body 51 can be steel plates.

[0044] In other optional embodiments, the number of the second support beams 53 can also be set to two, four or more, which can be flexibly set according to actual needs and is not specifically limited here.

[0045] Alternatively, if Figure 1 and Figure 2 As shown, the anti-fall plate 5 further includes two reinforcing ribs 54, both of which are located below the plate body 51 and are inclined, and one end of each reinforcing rib 54 is connected to the corresponding first support beam 52, and the other end is connected to the corresponding longitudinal beam 11, thereby further improving the overall structural strength of the anti-fall plate 5. In order to ensure the structural strength of the reinforcing rib 54, the reinforcing rib 54 can be selected as angle steel, and is fixed to the first support beam 52 and the longitudinal beam 11 by welding.

[0046] Furthermore, if Figure 2 As shown, one end of the first support beam 52 close to the ladder body 1 can abut against the side 10 of the hull, thereby forming a stable support for the lower part of the entire side cage to prevent it from shaking.

[0047] In this embodiment, if Figure 2 As shown, a rubber protective pad 55 is fixed to one end of the first support beam 52 that abuts against the ship hull side 10. By providing the rubber protective pad 55, it is possible to ensure that the ship hull side 10 is not damaged.

[0048] like Figure 1 and Figure 4 As shown, the top sides of the ladder body 1 are respectively welded with lifting ears 6. The lifting ears 6 are provided with lifting holes, which can be connected with lifting equipment by bolts, so as to facilitate the lifting of the cage to a desired position.

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
