Marine three-section folding vehicle springboard structure

Abstract

The invention relates to a marine three-section folding vehicle springboard structure, which relates to the technical field of marine vehicle springboards, and comprises a first section of springboard, a second section of springboard, a third section of springboard and a first section of wing plate which are sequentially connected from a roll-on-roll-off deck, rotatable connecting devices are arranged between the roll-on-roll-off deck and the first section of springboard, between the first section of springboard and the second section of springboard, between the second section of springboard and the third section of springboard, and between the third section of springboard and the first section of wing plate. A locking device is additionally arranged between the first section of springboard and the second section of springboard and / or between the second section of springboard and the third section of springboard; when the first section of springboard is folded upwards relative to the roll-on-roll-off deck, the second section of springboard is folded downwards on the lower surface of the first section of springboard, the third section of springboard is folded upwards on the upper surface of the second section of springboard, and the first section of wing plate is folded downwards on the lower surface of the third section of springboard. The use of other layers of decks cannot be affected, the overall arrangement of a ship is guaranteed, and meanwhile better use safety of the vehicle gangplank is guaranteed.

Description

technical field [0001] The invention relates to the technical field of a marine vehicle springboard, in particular to a marine three-section folding vehicle springboard structure. Background technique [0002] For the ro-ro space of the ship, in order to facilitate the entry and exit of ro-ro vehicles, a vehicle springboard is often provided as a set. Since the height difference between the ro-ro deck where the vehicle springboard is located and the wharf plane is a variable, and the downward use angle of the vehicle springboard is generally between 8 and 11 degrees at most, this makes the length of the vehicle springboard often relatively long, such as attached figure 1 shown. [0003] The current vehicle springboard is mostly one section of springboard plus wing board or two sections of springboard plus wing board. When storing, because the length of this section of springboard (or the first section of the two sections of springboard) is longer, the top of the vehicle sp...

Problems solved by technology

[0003] The current vehicle springboard is mostly one section of springboard plus wing board or two sections of springboard plus wing board. When storing, because the length of this section of springboard (or the first section of the two sections of springboard) is longer, the top of the vehicle springboard is much higher than where the vehicle springboard is located. Ro-Ro decks (two decks or even three decks high), affect the use of other decks and affect the appearance, such as attached figure 2 shown

[0004] Especially for ship arrangements with ro-ro spaces (such as multi-purpose ships or research and official ships), it will especially affect the overall arrangement of the ship, such as attached image 3 As shown, the storage vehicle springboard can only partially raise the top deck, but since the top deck has its original functions (such as laboratories, equipment workshops, etc.), local elevation will affect the realization of the original functions
