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
The present invention's stealthy ladder access peculiar to vessel belongs to boats and ships gangway ladder field.
Background technology
Boats and ships are because the requirement of himself and the regulation of industry standard and rules, its deck has different requirements to the distance (freeboard) of the water surface according to the difference of the navigable zone of boats and ships, and this freeboard depth is in general all than higher, goes ashore on easily for personnel and goods and materials and brings bigger influence.Generally, the internal and international large ship of going up adopts external hanging type gangway ladder or rope ladder, and spitkit adopts the mode of interim overlap joint springboard to solve the access issues of going ashore.There are part yacht and specialized salvage service ship to adopt permanent fixedly ladder access to solve the access issues of going ashore, but this fixedly ladder access has taken bigger floor space, made originally and became narrower and small with regard to limited deck usable floor area, simultaneously the opening on the deck has also brought potential safety hazard to the personnel on the ship, and therefore a kind of convenience and the safety passage of going on board is even more important for spitkit.
Summary of the invention
The purpose of this invention is to provide a kind of stealthy ladder access peculiar to vessel; during folding playback of the corresponding engagement of this ladder access is the part of this deck in ship structure and freeboard; after stealthy ladder access launches; then become from deck in ship structure and stretch the ladder passage that reaches to waterline, effectively protected the deck in ship structure usable floor area, and do not influence the outward appearance of boats and ships; when needs use; launch promptly to form firm passage behind the ladder access, thereby reach the reduction freeboard, make things convenient for the purpose of going ashore on personnel and the goods and materials.
The objective of the invention is to be achieved through the following technical solutions:
The present invention's stealthy ladder access peculiar to vessel, by fixedly ladder access and movable ladder access are formed, movable ladder access and fixedly the ladder of ladder access can be meshing with each other, the two connects by the hinge that is installed on the fixing ladder access, movable ladder access and fixing ladder access are by realizing folding with being connected of hydraulically powered unsteady connecting rod mechanism or launching, when spurred by hydraulic actuating cylinder, movable ladder access and the fixedly folding playback of ladder access, hidden under the deck, in the cabin body of ship side inboard, the bottom surface of its movable ladder access, the back side is respectively as deck in ship structure, the corresponding deck plane of the part of side board face and hull, the side board face coincide and is one; When being subjected to cylinder pushes, when movable ladder access launched, movable ladder access relative fixed ladder access constituted the continuous ladder access of one that extends downward the water surface to the shipboard side of a ship 180 degree that turn up.
Above-mentioned unsteady connecting rod mechanism is made up of unsteady connecting rod and crank, one end of unsteady connecting rod is connected with hydraulic ram through bearing pin, its other end is articulated and connected through the hinge of bearing pin and movable ladder access, one end of crank is connected in the middle of bearing pin and unsteady connecting rod, and the other end then is connected with the fixing hinged-support of ladder access through bearing pin.
Above-mentioned ladder access stepped surfaces is equipped with anti-skidding net
The continuous ladder access of one that above-mentioned movable ladder access launches to constitute is provided with movable hand rail.
The present invention's stealthy ladder access design innovation peculiar to vessel, change normal external hanging type gangway ladder, the rope ladder that adopts of ship domain, or spitkit adopts usual manners such as interim overlap joint springboard, at home and abroad adopt first the connecting rod mechanism that promotes by hydraulic ram drive folding mutually movable ladder access and fixedly ladder access finish and launch and a kind of boats and ships gangway ladder of jackknife action designs, movable ladder access and fixedly ladder access be connected through the hinge, the two ends of unsteady connecting rod are hinged with movable ladder access and hydraulic ram respectively, one end of crank is connected with unsteady connecting rod, its other end and fixedly ladder access is hinged.So the design's movable ladder access and crank have center of gyration separately, movable ladder access rotates around it and the fixing hinge between the ladder access, crank is around the hinge through that is installed on the fixing ladder access, hydraulic ram, connecting rod floats, crank and movable ladder access constitute the lever system of a continuous conversion of the strong point, avoided the stressed dead point of fixed pivot lever overturn system, therefore can by the push-and-pull power of oil cylinder smoothly realization activity ladder access with respect to the fixedly expansion and folding running of ladder access, simple operation, running is stable, after movable ladder access playbacks with fixedly ladder access is folding, hidden under the deck, in the cabin body of ship side inboard, the bottom surface of its movable ladder access, the back side is respectively as deck in ship structure, the corresponding deck plane of the part of side board face and hull, the side board face coincide and is one, ladder access is the part of hull when boats and ships normally navigate by water, do not reduce floor space, do not influence the outward appearance of boats and ships; Need ship time expansion ladder access up and down personnel and goods and materials, form the stable one continuous passage that leads to the water surface, reduced freeboard depth effectively, and safety rail is installed, make things convenient on the personnel and go ashore, the ladder access stepped surfaces is equipped with anti-skidding net, so ladder access is safe and reliable.
