The deck ladder can be suitable for the vertical, longitudinal and lateral translations of the ship due to the tiding and other causes, the horizontal stabilities of the deck ladder for the ship and a deck plane are enabled to be maintained during the complete supply operation, the ergonomic environment of a deck end is effectively improved during the accommodation ladder supply operation, so a more reliable and humanized boarding operation function is provided.
Description
Technical field
The present invention relates to a kind of follow-up horizontal deck of ship ladder, be particularly useful for delivery ship far away apart from harbour, tidal range fluctuation is larger, and the place that supply environment is more severe, belongs to supply equipment technology field, naval vessel.
Background technology
Marine gangway is the wider equipment of application in naval vessel supply facility, for surface vessel provides the passage of going ashore on crewman.Mainly formed by harbour end stand, springboard and deck ladder, build at harbour with between being subject to ship, form the passage of going ashore on crewman.Because supply environment varies, for ensureing the safety of crewman's lives and properties, the structure of marine gangway is made every effort to accomplish safe reliable, simplifies the operation of replenishment operation simultaneously, the production time of going ashore in shortening, and the passage of going ashore on accessible, more smooth and easy and safer is provided.But according to the applicant understood,, the most gunnel external hanging type structures that adopt of this type of equipment of most, have omitted harbour end stand and deck ladder, or have adopted the deck ladder structure that is fixed on springboard main body.Particularly for large-scale being subject to naval vessel; because hull own is tall and big; in addition the distance between deck and the harbour causing because of factors such as tidal range variations in naval vessel stop process and diff-H fluctuation; usually can form and harbour between laterally, longitudinally, height direction displacement and be subject to rolling, the pitching to ship self; the variation of these supply environmental parameterss can be followed replenishment operation overall process conventionally, and the impact uncertainty that can aggravate supply environment producing that interacts.Now, can deck of ship gangway ladder provide good feed channel just to seem particularly important.And above-mentioned conventional deck ladder structure obviously cannot adapt to this comparatively severe supply environment completely, the structure of self cannot meet self adaptation and be subject to the requirement that moves and wave to accommodation, can not form safety, feed channel smoothly at deck end by building very easily operation.
Summary of the invention
The object of the invention is to: by changing gangway ladder springboard, deck ladder and being subject to the relation to auxiliary connection between boat deck, be subject to the connection structure to ship and marine gangway from structure optimization, meet and be subject to under the relative harbour drift of ship and jacking conditions, adjust in real time equipment attitude, the requirement of self adaptation supply environment, and ensure all can form reliably under any nourishment condition, feed channel smoothly.
In order to reach above object, the invention provides a kind of follow-up horizontal deck of ship ladder, comprise deck ladder framework, safety barrier and be located at the running roller parts of described deck ladder base of frame, on described deck ladder framework, there is one group of going on board and mark time upwards, on the deck ladder framework of the both sides of marking time of going on board described in described safety barrier is installed on; The running roller parts of described deck ladder base of frame comprise rubber rolling assembly and universal wheel component, described rubber rolling assembly is installed on the deck ladder base of frame near gangway ladder springboard one side, and described universal wheel component is installed on the deck ladder base of frame away from gangway ladder springboard one side; Described deck ladder framework and described gangway ladder springboard are articulated with on the running roller bearing pin of described rubber rolling assembly.
The present invention further limits technical scheme, aforesaid follow-up horizontal deck of ship ladder, described rubber rolling assembly comprises running roller bearing pin, axis pin base, axle sleeve, rubber rolling, nylon jacket and pad, in running roller bearing pin in described deck ladder framework, be installed with successively described rubber rolling, nylon jacket and rubber rolling, two running roller end part of pin shafts in described deck ladder framework outside are equipped with described axle sleeve, axis pin base and pad from the inside to the outside, and are fixed in the end of described running roller bearing pin through spring cotter.
Aforesaid follow-up horizontal deck of ship ladder, described universal wheel component is made up of at least two cardan wheels, and the castor that described cardan wheel is installed on deck ladder framework supports.
Further, aforesaid follow-up horizontal deck of ship ladder, described safety barrier is demountable structure, and described safety barrier front end is provided with the structure of protracting, ensure to be subject to can form at high point and utmost point low spot the complete protection being combined to form by the safety barrier of springboard guardrail and follow-up horizontal deck of ship ladder to ship.
When follow-up horizontal deck of ship ladder operation of the present invention, can directly be placed in and be subject to boat deck, without special anchor fitting, under severe nourishment condition, also can rely on the orderliness on deck auxiliary fixing with rope, be subject to ship structural modification little.Coordinate gangway ladder springboard to be combined to form adaptive structure, provide weather-proof safe feed channel, and it is also comparatively easy to build operation.
Beneficial effect of the present invention: the present invention is connected in the ship end of the gangway ladder of going on board by bearing pin, when operation, be directly positioned over respective regions on naval vessel, fix by being subject to postive stop baffle and safety line to ship, can do among a small circle and move at put area according to field demand, and can adapt to because being subject to ship of causing of the reasons such as tiding is upper and lower, front and back, the translation of left and right, ensure that the omnidistance deck of ship ladder of replenishment operation keeps and the horizontal stability of deck level, effectively improve the human engineering environment of gangway ladder replenishment operation deck end, provide more reliable, the more humane warship operation function of stepping on.The present invention not only novelty simple in structure, workable, implementing process is good, and owing to having adopted adaptive structural principle, Job Operations is more convenient, faster.
