[0004] To achieve the above purpose, the utility model adopts the following technical scheme: A combined ladder for a cargo hold of a cargo ship, comprising:

[0005] A first straight ladder is arranged on the cargo hold bulkhead. A first conversion platform is arranged below the first straight ladder. An inclined ladder is arranged on the side of the first conversion platform. A second conversion platform is arranged on the side of the inclined ladder away from the first conversion platform. A second straight ladder is arranged on the side of the second conversion platform away from the inclined ladder; the inclination angle of the inclined ladder is 30 degrees.

[0006] Preferably, the top of the first straight ladder is flush with the cargo ship deck.

[0007] Preferably, a protective structure is arranged on the side wall of the cargo hold. The first straight ladder, the first conversion platform, the inclined ladder, the second conversion platform and the second straight ladder are all located inside the protective structure; the protective structure is a shell-like structure with a cavity inside.

[0008] Preferably, guardrails are arranged on the first conversion platform, the second conversion platform and the inclined ladder.

[0009] Preferably, observation openings are arranged on the protective structure corresponding to the first conversion platform and the second conversion platform.

[0010] Preferably, the first straight ladder is directly above the first conversion platform.

[0011] Preferably, the side of the second conversion platform away from the inclined ladder is in contact with the side of the second straight ladder.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are as follows:

[0013] 1. A combined ladder for a cargo ship's cargo hold provided by the present utility model. The top of the first straight ladder is connected to the deck, and the bottom of the second straight ladder is connected to the bottom of the cargo hold. Workers can move through the first straight ladder to the first conversion platform, then move from the first conversion platform to the second conversion platform through the inclined ladder, and then descend into the cargo hold through the second straight ladder. According to the depth of the cargo hold, the length or number of the straight ladders can be adjusted to adapt to different cargo holds. The straight ladders are attached to the cabin wall and have no bending angles, so they are simple to manufacture, not easily deformed, and occupy less space.
