Abstract
The utility model discloses a novel boarding ladder, this boarding ladder include the ladder body, coupling mechanism and deck fixed knot construct, the ladder body includes ladder frame, arc and mark time, railing and lean on the bank wheel, the both ends that the arc was marked time set up respectively on two sides of ladder frame, mutually perpendicular between the direction at railing place and the direction that ladder frame extends, lean on the bank wheel to set up the lower tip at the ladder body, coupling mechanism includes coupling hook and anticreep round pin axle, the upper end fixed connection of coupling hook and ladder body. The utility model discloses special requirement based on LNG filling ship and form, personnel that can be applied to between other boats and ships are refuted. Compared with the common marine wharf ladder, the maximum using angle can reach 55 degrees.
Description
Technical Field
The utility model belongs to boats and ships equipment design and manufacturing field, concretely relates to boarding ladder's structure.
Background
Ship-to-ship docking operations are conventional operations between LNG filling ships and filled ships. Due to the special use of LNG filling vessels, vessel-to-vessel barge operations are very frequent. During barge operation, personnel transport is necessary. Along with the large-scale of the ship, the height difference of the connecting point between the injection ship and the filling ship is often large, and the difficulty of overcoming the height difference in personnel transportation is increased.
The common wharf ladder used at present is directly erected between two ships, does not have an effective fixing device, and has potential safety hazards when the two ships move relatively along with waves. The maximum use angle of the common wharf ladder is only 30 degrees, and in order to meet the requirement of large height difference, the length of the ladder needs to be correspondingly increased. And too long ladders will increase the difficulty of ladder handling.
Disclosure of Invention
An object of the utility model is to provide a more ordinary pier uses angle bigger, safer ladder of stepping on a ship to reduce the length and the weight of ladder, and reduce the influence of boats and ships relative motion to the ladder.
In order to achieve the above purpose, the utility model provides a technical scheme as follows:
a novel boarding ladder, which comprises a ladder body, a connecting mechanism and a deck fixing structure,
the ladder body comprises a ladder frame, arc steps, handrails and shore wheels, wherein two ends of each arc step are respectively arranged on two side edges of the ladder frame, the direction of each handrail is vertical to the extending direction of the ladder frame, the shore wheels are arranged at the lower end part of the ladder body,
the connecting mechanism comprises a connecting hook and an anti-falling pin shaft, and the connecting hook is fixedly connected with the upper end part of the ladder body.
The hook frame is connected with the connecting hook through an anti-falling pin shaft, and the rotating area of the hook frame is connected with the rotating area of the connecting hook through a connecting shaft.
And the arc-shaped steps are provided with anti-skid convex strips.
The rotation area of the connecting hook is in an omega shape, the steel connecting hook can be fully contacted with the hook rack within the working range of 0-55 degrees of the boarding ladder, the anti-falling pin shaft only has a safety protection effect, and the connecting hook is not stressed in the working process
The ladder frame, the arc-shaped steps and the railings are all made of aluminum parts so as to reduce the weight of the whole ladder.
A Teflon gasket is arranged between the connecting mechanism and the ladder body, so that electrochemical corrosion is avoided.
The connecting hook and the anti-falling pin shaft are made of steel.
The hanger frame is provided with a sliding area of the hanger, so that the ladder is allowed to move in the fore-aft direction of the ship to offset relative movement between the two ships.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses more ordinary marine pier ladder, it uses the biggest use angle can reach 55. The omega-shaped special shape of the steel connecting hook rotating area can effectively prevent the connecting hook from loosening from the deck fixing structure. The special design of the deck fixing structure can offset the influence of the relative displacement between ships on the ladder in the filling process. The hanger frame is provided with a section of sliding area of the hanger, which allows the ladder to move in the fore-aft direction of the ship so as to counteract the relative movement between the two ships.
