Remote outward-spreading translating gangway ladder

Abstract

The invention discloses a remote outward-spreading translating gangway ladder, comprising a guiding moving mechanism for driving the whole gangway ladder to translate and spread outwardly in relation to the ship side edge, and an outward-spreading traction system which outwardly spreads or inwardly contracts the droop end of the gangway ladder with the aid of a hanging bracket mechanism. The hanging bracket mechanism comprises a hanging bracket rail, a primary suspension arm, a secondary suspension arm, a translational lifting traction system and an outward-spreading traction system. When a ship arrives at a port and docks, the translational lifting traction system is started firstly to drive the gangway ladder to translate, then a steel rope is released and makes the droop end of the gangway ladder descends, and the outward-spreading traction system is started to achieve outward stretching movement of the secondary suspension arm in relation to the primary suspension arm in order to further achieve that the droop end of the gangway ladder hung by the secondary arm spreads outwardly to the dock to support. The droop end of the gangway ladder can spread outwardly and contract inwardly taking the upper platform as the centre such that it brings convenience for people to pass through safely when the ship docks. The invention is installed on the deck on the ship edge and has no interference with the upper layer deck. The invention has a big operation freedom and is convenient and reliable to use.

Description

technical field [0001] The invention relates to a ship deck machine, in particular, the invention relates to a long-distance outreach type translational gangway. Background technique [0002] On June 11, 2009, the International Maritime Organization IMO passed a MSC.1 / cire, 1331 resolution, which requires ships built on or after January 1, 2010 to use gangway and gangway for boarding and disembarking If conditions permit, it should be placed in an unobstructed work area, and the storage area should not store goods or have hanging objects above it. Therefore, the boarding and disembarkation ladders and springboards have been arranged at the stern for newly built ships. The stern of large or ultra-large ore carriers and bulk carriers has a large linear feature. If the middle part of the hull is docked, the side of the stern is about 2m to 6m away from the shore, and the gangway of the conventional structure type cannot reach this position. On the shore, it is not convenient ...

AI Technical Summary

Problems solved by technology

However, the existing technology also exposes some unreasonable structural problems in practical applications

For example, the outrigger gangway moves along the track that rests on the lower deck, and the high installation makes maintenance inconvenient

In addition, the inner hanger of the overhanging track is stored or lowered by pulling the gangway on the deck through the steel cable, which brings unsafe factors to the working area of ​​the gangway
