Description
Technical field
The present invention relates to a kind of gangway ladder.Specifically, be the not used time folding gangway ladder peculiar to vessel that to be recoverable in cabin, can to decontrol when using.
Background technology
All know in shipbuilding field no matter be on ship for civil use or military boats and ships, be all furnished with gangway ladder, to go ashore on people during boats and ships landing pier.At present, gangway ladder boats and ships are equipped with is all the traditional gangway ladder be separated with boats and ships of regular length.Length due to this gangway ladder is fixed and is separated with boats and ships, during use, by manpower transport, when being especially used in the heavier or boats and ships stop position of bearing load and water depth comparatively far field closed, not only require that the length of gangway ladder will be grown, but also require that the intensity of gangway ladder wants high.And the length one of gangway ladder is long, take up space just many.And being the requirement of strength meeting gangway ladder, the weight of gangway ladder is just heavy.Therefore, this gangway ladder needs multi agent cooperation just can operate, and makes the labour intensity of operating personal larger.Again because the length of this gangway ladder is fixed and is separated with boats and ships, during use, rely on personnel's manual operations completely, not only folding and unfolding degree of automation is low, and there is safety hazard.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of retractable collapsible gangway ladder peculiar to vessel.This retractable collapsible gangway ladder peculiar to vessel, takes up space less, folding and unfolding degree of automation is high, safe and reliable.
For solving the problem, take following technical scheme:
Retractable collapsible gangway ladder peculiar to vessel of the present invention comprises gangway ladder, be characterized in also comprising gangway ladder room, this gangway ladder room is on the deck near gun wale edge, and the gangway ladder room room wall adjacent with ship side has aperture of door and door-plate, door-plate vertical be hinged on the correspondence of aperture of door vertical on.Described gangway ladder contains epimere and hypomere, and the neighboring terminal of upper and lower section by hinge together.All there is the first key seat the middle both sides of epimere, and all have the second key seat near the hypomere both sides of pin jointed end, under gangway ladder relieving state, described first key seat and the second key seat are all in the upside of gangway ladder.Epimere and intersegmentally have the first hydraulic actuating cylinder down, the first hydraulic actuating cylinder two ends be hinged on respectively on the first key seat and the second key seat.The non-articulated end both sides of epimere are all connected with lower protruding block, deck inside door there are two the 3rd key seats, this two the 3rd key seat is corresponding with two lower protruding blocks respectively, the outer end of two lower protruding blocks is hinged on the upper end of two the 3rd key seats respectively, have two the second hydraulic actuating cylinders between the non-articulated end of epimere and the 3rd key seat, the two ends of the second hydraulic actuating cylinder are hinged on the non-articulated end of epimere and the lower end of the 3rd key seat respectively.Aperture of door has winch inside top, and the roll shaft of winch is parallel with aperture of door top, has two steel ropes between winch and gangway ladder, and one end of two steel ropes is connected on the roll shaft of winch, and the other end is connected to the two ends of bearing pin.
Further improvement of the present invention scheme is, the deck in gangway ladder room has two for when gangway ladder is regained to gangway ladder position first hook.
Further improvement of the present invention scheme is, has the 3rd hydraulic actuating cylinder automatically opened or closed for door-plate between the hinged limit of aperture of door and door-plate, on the hinged limit that the two ends of the 3rd hydraulic actuating cylinder are hinged on aperture of door respectively and on the door-plate medial surface on contiguous hinged limit.
Further improvement project of the present invention is, under gangway ladder relieving state, all has detachable and determine handrail on the upside of gangway ladder both sides.
Take such scheme, have the following advantages:
As can be seen from the above scheme, due to containing gangway ladder room, this gangway ladder room is on the deck on gun wale edge, and the gangway ladder room room wall adjacent with ship side has aperture of door and door-plate, door-plate vertical be hinged on the correspondence of aperture of door vertical on.Described gangway ladder contains epimere and hypomere, and the neighboring terminal of upper and lower section by hinge together.All there is the first key seat the middle both sides of epimere, and all have the second key seat near the hypomere both sides of pin jointed end, under gangway ladder relieving state, described first key seat and the second key seat are all in the upside of gangway ladder.Epimere and intersegmentally have the first hydraulic actuating cylinder down, the first hydraulic actuating cylinder two ends be hinged on respectively on the first key seat and the second key seat.The non-articulated end both sides of epimere are all connected with lower protruding block, deck inside door there are two the 3rd key seats, this two the 3rd key seat is corresponding with two lower protruding blocks respectively, the outer end of two lower protruding blocks is hinged on the upper end of two the 3rd key seats respectively, have two the second hydraulic actuating cylinders between the non-articulated end of epimere and the 3rd key seat, the two ends of the second hydraulic actuating cylinder are hinged on the non-articulated end of epimere and the lower end of the 3rd key seat respectively; Aperture of door has winch inside top, and the roll shaft of winch is parallel with aperture of door top, has two steel ropes between winch and gangway ladder, and one end of two steel ropes is connected on the roll shaft of winch, and the other end is connected to the two ends of bearing pin.During use, open door-plate, first overhanging by the piston rod of the second hydraulic actuating cylinder, the gangway ladder of folded state is first shifted out outside aperture of door around the hinge-point of its epimere and the 3rd key seat, make epimere by the overhanging of the second hydraulic cylinder piston rod and winch again and intersegmentally to rotate to being in a straight line in deployed condition around bearing pin outward, thus realize the expansion of gangway ladder and put down.During withdrawal, first shunk by the piston rod of the first hydraulic actuating cylinder, make their hinge-point of hypomere spaced winding be rotated upwardly to rugosity, then by the retraction of the second hydraulic cylinder piston rod and the contrarotation of winch, the gangway ladder of folded state is moved in aperture of door.As can be seen here, do not need manual operations, just can realize retractable operation, not only degree of automation is high, and without safety hazard.Again owing to not needing manual operations, just can realize retractable operation, greatly can reduce the labour intensity of operating personal.In addition, because gangway ladder can fold, take empty less, useful space on naval vessel can be saved.
