Problems solved by technology

If the gangway is still arranged on the main deck, first of all, because the gangway is long, the space occupied by the storage is relatively large. In order to reduce the volume as much as possible, a telescopic inclined ladder is required, which is inconvenient to use. Secondly, after the gangway is lowered, In order to achieve the ballast draft, the length of the gangway will be relatively long, and it can reach about 35m for ultra-large container ships. Because people walk around when boarding the ship, it will cause the gangway to shake naturally, which is prone to resonance
In order to ensure the safety of boarding personnel, the number of people boarding at the same time is generally controlled, which causes great inconvenience in use

Abstract

The invention discloses a reinforcement structural form of an embedded accommodation ladder of an ultra-large type container ship. The reinforcement structural form comprises two local reinforcing frames, an open hole, accommodation ladder transmission shafts and rotary supporting plates, wherein the two local reinforcing frames are arranged in a warehouse of the ultra-large type container ship, each local reinforcing frame comprises a vertical-direction girder and a local toggle plate, the local toggle plates are close to the areas of boardsides, and the vertical-direction girders are arranged on one sides, back to the local toggle plates, of the local reinforcing frames; the open hole is formed in an outer plate of the ultra-large type container ship, and the open hole penetrates into the warehouse of the ultra-large type container ship; the accommodation ladder transmission shafts are arranged in the open hole in the length direction of a ship body of the ultra-large type container ship, and the accommodation ladder transmission shafts are located on one sides, facing the vertical-direction girders, of the local toggle plates; and the rotary supporting plates are rotatably connected to the accommodation ladder transmission shafts, and the rotary supporting plates support an accommodation ladder. According to the reinforcement structural form of the embedded accommodation ladder of the ultra-large type container ship, the form of the open hole of the outer plate is optimized through the reasonable design, and the requirement for fatigue strength is met; and in addition, the positions of the local reinforcing frames are arranged, the sizes of the local reinforcing frames are optimized, the strength of the open hole position of the outer plate of the ship body is met, the passing requirements of the personnel are met, and meanwhile the mechanical operation of the accommodation ladder is guaranteed.

Description

technical field [0001] The invention relates to the technical field of ultra-large container ships, in particular to the technical field of a reinforced structure form of a built-in gangway of an ultra-large container ship. Background technique [0002] The gangway of a container ship is generally stored in the side area of ​​the main deck. When in use, it is lowered by a steel cable, which can ensure the safety of people boarding the ship when the ship is at various drafts. For ultra-large container ships, due to the higher molded depth, the main deck is farther from the waterline. If the gangway is still arranged on the main deck, first of all, because the gangway is long, the space occupied by the storage is relatively large. In order to reduce the volume as much as possible, a telescopic inclined ladder is required, which is inconvenient to use. Secondly, after the gangway is lowered, In order to achieve the ballast draft, the length of the gangway will be relatively lo...
