Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0021] Such as figure 1 Shown, a kind of marine inclined ladder door / cover installed between the upper and lower decks A and B. The inclined ladder door comprises a ladder frame 1 composed of two mutually parallel bottom ladder frames 11 and a face ladder frame 12, between the bottom ladder frame 11 and the face ladder frame 12, there are multiple stages of pedals 2 parallel to each other hinged longitudinally, The face ladder frame 12 is provided with handrails 4 . The top of the ladder frame 1 is hinged with the upper deck A, and the bottom end of the ladder frame 1 is against the lower deck B.

[0022] The ladder frame 1 can freely rotate around the hinge point between it and the upper deck A. With the rotation of the ladder frame 1, the bottom ladder frame 11 and the face ladder frame 12 will be displaced relatively, and the angle of the peda...

Abstract

The invention discloses a marine inclined ladder door / cover, and belongs to the technical field of ships. The marine inclined ladder door / cover is mounted between an upper deck and a lower deck, and characterized by comprising a ladder assembly; the ladder assembly comprises a bottom ladder frame and a surface ladder frame which are parallel to each other; multi-stage parallel steps are vertically hinged between the bottom ladder frame and the surface ladder frame; the top end of the ladder assembly is hinged to the upper deck; the bottom end of the ladder assembly is propped against the lower deck; the ladder assembly can upwards rotate around the hinge point between the ladder assembly and the upper deck to seal the opening of the upper deck. The marine inclined ladder door / cover is simple in structure, convenient to operate and dual in purpose, and has the advantages that not only can people on a ship be protected when necessary, but also additional building cost is avoided.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship inclined ladder door / cover. Background technique [0002] Now the inclined ladders for ships are all steel structures with both ends fixed on the upper and lower decks. It is very convenient to use as a fixed passage, and the structural form is very mature. In order to pass through, the upper end must overlap the edge of the upper deck, or open a hole in the upper deck. Due to the limited deck area on the ship, there are many ways to install inclined ladders through deck openings. [0003] During the actual ship navigation, many ships need to consider the facilities to prevent pirates. It is mainly to prevent pirates from entering control places such as living areas or cabs. However, the existing inclined ladder passage and deck openings do not have any safety facilities for preventing pirates from entering. There are also some ships that separately set a grille cover or...
