[0002] The hydraulic gangway, also known as a gangway, is a movable ladder installed on both sides of a ship for passengers to get on and off the ship. It is made of wood or metal and consists of upper and lower platforms, ladder frames, ladder steps, railings, handrails, and hoisting devices. When the ship is sailing, it is hoisted up and stored on the deck. When in use, it is lowered and hung on the side of the ship. The gangway device is commonly used on passenger ships and other large and medium-sized ships.

[0003] Publication No. CN218463817U discloses a gangway platform quick fixing device, which includes a gangway body and a platform body. The gangway body is characterized in that: the platform body is arranged at the end of the gangway body, the gangway body and the platform body are mutually attached on one side and fixed with a sleeve rod, the surface of the sleeve rod is sleeved with a sleeve groove, the sleeve groove is arranged at the end of the platform body, the inner wall of the sleeve groove is fixed with an insertion rod, the surface of the insertion rod is sleeved with an insertion groove arranged in the middle of the sleeve rod, the surface of the platform body is fixed with a sliding groove, the inner part of the sliding groove is provided with a sliding block and a spring, the two sides of the spring are respectively abutted on the surface of the sliding block and the inner wall of the sliding groove, the surface of the sliding block is fixed with a connecting rod penetrating through the sliding groove, the end of the connecting rod is fixed with a traction rod, the surface of the traction rod is sleeved with a traction groove arranged in the inner wall of the gangway body, the sleeve groove is arranged as a waist-shaped groove, the sleeve rod is arranged as a waist-shaped block matched with the waist-shaped groove, the opening of the insertion groove is arranged as a horn-shaped opening, and the end of the insertion rod is arranged as an inclined chamfer. The device improves the convenience of fixing the platform body on the gangway body. However, in actual use, the device and existing equipment can only be used after the ship is docked.
