The invention relates to the technical field of ship engineering, and discloses a boarding ladder which comprises a connecting frame, a rotating frame, a plurality of pedals, a connecting rod and a push-pull rod, the connecting frame is detachably connected to one side of a ship body, the upper end of the rotating frame is hinged to the upper end of the connecting frame, and the pedals are sequentially hinged to the rotating frame from top to bottom at intervals; the connecting rod and the rotating frame are arranged in parallel at intervals; one end, close to the connecting frame, of each pedal is hinged to the connecting rod; one end of the push-pull rod is hinged to the connecting frame, and the other end of the push-pull rod is hinged to the connecting rod; when the rotating frame is rotated to the unfolding position in the direction away from the connecting frame, the push-pull rod pulls the connecting rod to move downwards in the direction away from the rotating frame, so that the connecting rod drives the pedals to rotate to the horizontal state, and the boarding ladder is unfolded and kept stable; when the rotating frame is rotated to the folding position in the direction close to the connecting frame, the push-pull rod pushes the connecting rod to drive the pedals to rotate to be in an upward inclining state, and therefore folding of the boarding ladder is achieved.
本发明涉及船舶工程技术领域,公开一种登船梯,包括连接架、转动架、多个踏板、连接杆和推拉杆,连接架可拆卸连接在船体的一侧,转动架的上端与连接架的上端铰接,各踏板从上至下依次间隔铰接在转动架上;连接杆与转动架平行间隔布置,各踏板靠近连接架的一端均与连接杆铰接;推拉杆的一端与连接架铰接,推拉杆的另一端与连接杆铰接;向远离连接架的方向转动转动架至展开位时,推拉杆拉动连接杆向下、向远离转动架的方向移动,从而使得连接杆带动各踏板转动至水平状态,使得登船梯得以展开且保持稳定;向靠近连接架的方向转动转动架至折叠位时,推拉杆推动连接杆带动各踏板转动至上倾状态,从而实现对登船梯的折叠。
