Marine invisible ladder way

Abstract

The invention provides a marine invisible ladder way, and belongs to the field of accommodation ladder of a ship. The marine invisible ladder way comprises a fixed ladder way and a movable ladder way, wherein, ladders of the movable ladder way and the fixed ladder way can be meshed with each other; the movable ladder way is connected with the fixed ladder way through a hinge mounted on the fixed ladder way; the movable ladder way and the fixed ladder way are folded or expanded through being connected with a hydraulic drive floating connecting rod mechanism, and the operation is convenient and fast and the running is steady; after being folded and restored to the original positions, the movable ladder way and the fixed ladder way are hidden below a deck and in a cabin body on the inner side of a ship board; the bottom surface and the back surface of the movable ladder way of the marine invisible ladder way, which respectively serve as a part of the deck of a ship body and a part of a side board surface of the ship body, coincide with the corresponding deck surface and the corresponding side board surface of the ship body to form a whole and become a part of the ship body, so that the area of the deck is not reduced, and the appearance of the ship cannot be influenced; when the marine invisible ladder way needs to be expanded during ship embarkation and disembarkation, the movable ladder way turns outwards at an angle of 180 degrees towards the side board of the ship relative to the fixed ladder way under the push of a hydraulic cylinder, thereby forming an integrated continuous ladder way extending downwards to the water surface, effectively reducing the height of a freeboard, and facilitating ship embarkation and disembarkation of people.

Description

technical field [0001] The invention discloses an invisible ladderway for ships, which belongs to the field of ship gangway. Background technique [0002] Due to the ship's own requirements and the provisions of industry norms and regulations, the distance (freeboard) from the deck to the water surface has different requirements according to the different navigation areas of the ship, and the height of the freeboard is generally relatively high. The convenient disembarkation and disembarkation of personnel and materials has a relatively large impact. Usually, large domestic and international ships use external gangway ladders or rope ladders, and small ships use temporary overlapping springboards to solve the problem of getting on and off the ship. Some yachts and professional rescue ships use permanent fixed stairway to solve the problem of access to and from the ship, but this kind of fixed stairway takes up a large deck area, making the originally limited deck use area n...

AI Technical Summary

Problems solved by technology

Some yachts and professional rescue ships use permanent fixed stairway to solve the problem of access to and from the ship, but this kind of fixed stairway takes up a large deck area, making the originally limited deck use area narrower, and the deck on the deck Openings also pose a safety hazard to people on board, so a convenient and safe boarding channel is especially important for small ships
