The invention discloses a folding rotary gangway ladder, and belongs to the technical field of gangway ladders, the gangway ladder comprises a base, a connecting platform movably connected with the base and a gangway ladder frame movably connected with the connecting platform, and the base is provided with a first telescopic mechanism used for adjusting the pitching angle of the connecting platform; a second telescopic mechanism used for changing the pitching angle of the gangway ladder assembly is arranged on the connecting platform, the connecting platform is parallel or pitching up relative to the base through the first telescopic mechanism, and the gangway ladder assembly is parallel or pitching down relative to the connecting platform through the second telescopic mechanism. The connecting platform and the gangway ladder frame of the gangway ladder can be relatively folded and contracted to the upper part of the base, so that the occupied space during storage is greatly reduced; the folded folding ladder frames are stacked together, so that the occupied space is extremely small; the distance between the lower end of the gangway ladder and the ship is adjustable, and the gangway ladder can be used at different distances from a gunwale to a wharf; the gangway ladder can be stored in a gangway ladder room or behind a gunwale wall, erosion of sea wind and seawater is reduced, and the service life of the gangway ladder is prolonged.
本发明公开了一种折叠回转舷梯,属于舷梯技术领域,该舷梯包括基座、与基座活动连接的连接平台以及与连接平台活动连接的舷梯架,基座上设有用于调节连接平台俯仰角度的第一伸缩机构,连接平台上设有用于改变舷梯架俯仰角度的第二伸缩机构,连接平台通过第一伸缩机构相对于基座平行或上仰,舷梯架通过第二伸缩机构相对于连接平台平行或下俯。本发明舷梯的连接平台和舷梯架可相对折叠并收缩到基座上方,极大地减少收纳时占用空间;折叠后的折叠梯框堆叠在一起,占用空间极少;舷梯下端相对于船舶的距离可调节,在舷边到码头的不同距离上都可使用;舷梯可收纳在舷梯房或者收纳在舷边壁后,减少海风、海水的侵蚀,提高舷梯使用寿命。
