Deck ladder for follow-up horizontal ship

Abstract

The invention relates to a deck ladder for a follow-up horizontal ship, which belongs to the field of ship supply equipment, and comprises a deck ladder framework, a safety guardrail and a rolling wheel component which is arranged at the bottom part of the deck ladder framework, wherein a group of upward boarding steps are arranged on the deck ladder framework, and the safety guardrail is installed on the deck ladder framework at the two sides of the boarding steps; the rolling wheel component at the bottom of the deck ladder framework comprises a rubber rolling wheel assembly and a universal wheel component, the rubber rolling wheel is installed at the bottom of the deck ladder framework, which is close to one side of an accommodation ladder springboard, and the universal wheel component is installed at the bottom of the deck ladder framework, which is far away from the side of the accommodation ladder springboard; and the deck ladder framework and the accommodation ladder springboard are hinged onto a rolling wheel hinge pin of the rubber rolling wheel assembly. 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 [0001] The invention relates to a follow-up horizontal marine deck ladder, which is especially suitable for a place where a supply ship is far away from a wharf, where the tidal range fluctuates greatly and the supply environment is harsh, and belongs to the technical field of ship supply equipment. Background technique [0002] The marine gangway is a widely used equipment in the ship supply facility, which provides the channel for the crew to get on and off the ship for the surface ship. It is mainly composed of a platform at the dock end, a springboard and a deck ladder, and is built between the dock and the receiving ship to form a passage for the crew to get on and off the ship. Because the replenishment environment varies widely, in order to ensure the safety of the crew’s life and property, the structure of the marine gangway strives to be safe and reliable, while simplifying the operation of the replenishment operation, shortening the time for disemba...
