Description

Technical Field

[0001] The invention relates to the technical field of gangways, in particular to a novel gangway for medical ships. Background Art

[0002] The gangway of a medical ship is a movable ladder installed on both sides of a medical ship for people to get on and off the ship. It is usually made of wood or metal, and its structure includes upper and lower platforms, ladder frames, steps, handrails and hanging ladder devices. When sailing, the gangway will be folded and properly stored on the edge of the deck. As an important equipment for boarding and leaving a medical ship, the gangway of a medical ship is usually able to accommodate multiple people when in use for the escape passage of a medical ship.

[0003] For example, the Chinese patent authorization announcement number is CN118025423A, "provides a ship gangway, a boarding platform installed on one side of the hull, one side of the boarding platform is rotatably connected to a gangway frame, the gangway frame includes two ladder beams arranged opposite to each other, each ladder beam includes a rotating connecting beam and a telescopic connecting beam connected together, the telescopic connecting beam is provided with a telescopic slide arranged along its length direction, and each telescopic slide is slidably connected to a sliding connecting beam; a plurality of staircases distributed along its length direction are connected between the two ladder beams, and both ends of each staircase and the boarding platform away from the boarding platform are rotatably connected to the rotating connecting beam, and each staircase and the boarding platform close to the corresponding ladder beam are slidably connected to the corresponding sliding connecting beam, and a driving motor for driving the staircase to rotate is installed on one side of one of the ladder beams; a support frame is provided on one side of the hull, and a first hydraulic telescopic rod is connected between the support frame and the gangway frame"; In the above-mentioned comparative document, the angle of the stairs can be freely adjusted according to the usage situation to prevent slipping when walking on the stairs.

[0004] However, when the above-mentioned medical ship gangway is used as an escape passage, after the gangway is quickly unfolded, the fences on both sides are too narrow and cannot be adjusted, resulting in the passage being unable to quickly accommodate multiple people to escape, greatly reducing the escape rate. In addition, the fences on both sides of the existing gangway have limited functions. After the fences are installed, they cannot be disassembled. When escaping and rescuing people, the passability of the medical stretcher is poor. Summary of the invention

[0005] The purpose of the present invention is to provide a new type of ship gangway, which can realize convenient assembly and disassembly of the fence after installation, facilitate the escape of multiple people in the escape passage, and enable the stretcher of the rescue personnel to pass smoothly and conveniently.
