Boarding ladder for ship

Abstract

The invention discloses a boarding ladder for a ship. The boarding ladder comprises handrails, a boarding ladder body and pedals. Two fixing supporting rods are symmetrically arranged on the boardingladder body and welded through second supporting rods which are arranged from top to bottom at equal intervals. The pedals are welded to rotary shafts correspondingly, rotary discs are rotatably connected to one sides of the ends of the fixing supporting rods, and the other sides of the ends of the fixing supporting rods are rotatably connected with a limiting frame through shaft sleeves. In the boarding ladder for the ship, when the height of the ship is not consistent with the elevation of a dock, the pedals are made to be parallel to the horizontal plane by rotating the rotary discs so thatthe stairway-shaped boarding ladder can be formed; when the height of the ship is consistent with the elevation of the dock, similarly, the pedals are made to be parallel to the horizontal plane so that a horizontal bridge can be formed; and through the structure, the applicability of the boarding ladder can be higher, bridge connection of different positions and heights can be met simultaneously, and convenience is brought to boarding.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to a ship boarding ladder. Background technique [0002] The boarding ladder is a device for loading and unloading operators and crew members to safely and smoothly get on and off the ship when the oil tanker in the modern large oil tanker wharf is docking at the wharf. The traditional boarding device is completed by the gangway carried by the ship itself. During the development of the oil tanker wharf, the modern large-scale oil tanker wharf, especially the unshielded pier type wharf, the wharf surface is not completely continuous, and the elevation is relatively high. High, the ship bumps and swims frequently during the operation, and the range is relatively large. Due to the large fender of the wharf, the distance between the side of the ship docked on the wharf and the shoreline of the wharf is relatively large. The ship-shore connection under this condition is carried by...

Problems solved by technology

[0003] However, the existing boarding ladder has a single function, and its structure is often in a fixed state, so that this boarding ladder can only be used for boarding where the ship's side is inconsistent with the wharf elevation, and in some cases, the ship's side may It will be consistent with the elevation of the wharf, and the ship cannot effectively approach the wharf. In this case, the traditional boarding ladder will not be able to meet the boarding requirements, and a bridging structure is needed to replace it.
