Abstract

The invention provides a unidirectional chain type extendable gangway ladder, which comprises an extendable gangway ladder main body, a gangway ladder extension mechanism, a gangway ladder pitching mechanism, an entire dragging machine frame device and a safety guardrail; the extendable gangway ladder main body comprises at least one section of extendable ladder and one section of fixed ladder; the gangway ladder extension mechanism comprises a rotating shaft, a chain wheel arranged on the rotating shaft, a unidirectional chain of which one end is fixed on the outmost section of extendable ladder and of which the other end is meshed with the chain wheel, and a driving mechanism which is connected with the rotating shaft through a clutch; and the gangway ladder pitching mechanism comprises a rope winding wheel which is connected with the driving mechanism through a clutch and a steel wire rope of which one end is wound on the rope winding wheel and of which the other end is connected with the front end of the fixed ladder. In the invention, the unidirectional chain type extendable gangway ladder is driven by a motor or manually, the extended length and angle of pitch of the gangway ladder can be regulated according to the position relationship between a ship body and a wharf, and the problem of safety channel between small and medium ships and warships and variable wharves and berths is solved.

Description

technical field [0001] The invention relates to a gangway, in particular to a gangway for building a safe passage connecting a ship and a wharf. Background technique [0002] At present, when small and medium-sized warships are docked at the docks, they generally use manually carried fixed-length gangway to overlap the safe passage. The reliability and safety of such gangway are often not easy to guarantee, and its operability is very poor for the situation that ships are moored at a long distance. Based on the above situation, there is an urgent need for a portable simple telescopic gangway that is highly reliable, easy to operate, and highly automated. When designing the one-way chain telescopic gangway, how to realize the stretching and pitching motion of the gangway, and how to simplify the transmission mechanisms of the gangway are the key technical problems encountered in the design of the invention patent. The one-way chain telescopic gangway invented by us through ...
