A method for judging the clear space of a ship's inclined ladder passage

Abstract

The invention provides a method for judging the net space of a ship's inclined ladder channel applied in the technical field of ship production and manufacturing. The ship's inclined ladder channel includes a lower platform (1), an upper platform (2), an inclined ladder (3), an inclined ladder The opening (4) is characterized in that: the judging method is: 1) establishing a calculation model of the posture of the personnel getting off the ladder and the net space of the inclined ladder; 2) obtaining a comparison table of the calculated value of the opening size of the inclined ladder mouth; 3 ) to obtain the figure of the person's body posture when going up and down the ladder; 4) to judge. The method for judging the net space of the inclined ladder channel of a ship according to the present invention can quickly determine whether the clear space of the inclined ladder channel meets the requirements, and the judgment standard is unified, the judgment result is reliable, the design quality of drawings is improved, and problems can be found in advance and structural optimization can be carried out , to avoid frequent rework on site, to ensure the design and manufacturing quality of the clear space of the ship's inclined ladder passage, and to meet the needs of the ship.

Description

technical field [0001] The invention belongs to the technical field of ship production and manufacturing, and more specifically relates to a method for judging the clear space of a ship inclined ladder passage. Background technique [0002] On ships with independent engine room and wheelhouse, there are generally inclined ladders to enter the engine room and upper deck. Some large ships have special indoor stairways inside the upper building, and open-air inclined ladders outside the upper building. , to facilitate the passage of the crew between the cabins of the ship and meet the needs of safe escape. Therefore, in the detailed design stage of the ship, it is necessary to correctly arrange the outdoor inclined ladders and indoor inclined ladders of the ship. ) recommended different angles of inclined ladders correspond to the minimum opening width and opening length, and the summary table of opening sizes for inclined ladder openings recommended by the CB standard is as f...

AI Technical Summary

Problems solved by technology

The problem existing in the prior art is that the opening size of some inclined ladders cannot meet the normal passage of the crew up and down the inclined ladder, while the minimum length in the CB standard refers to the clear space for passage, and this size itself is relatively small, so it is necessary for the crew to pass easily And the interior of the inclined ladder passage needs to be decorated, and the size of the structural opening needs to be enlarged according to the requirements of the convenience of passage and the space occupied by the interior decoration.

However, in the prior art, there is no accurate determination method for the minimum net size of the inclined ladder passage, resulting in the need for frequent rework
