Description

Technical Field

[0001] The utility model relates to the technical field of boarding gangways, in particular to a raisable boarding gangway. Background Art

[0002] The history of boarding gangways can be traced back to ancient times, when people had invented various forms of boarding and disembarking tools to board and disembark ships at sea. However, with the development of ships and the advancement of technology, boarding gangways have gradually evolved into a device specially designed for boarding ships. The original boarding gangways may be simple wooden structures, hanging along the side of the ship and operated by the crew on board. With industrialization and technological progress, boarding gangways began to be made of metal materials, and more mechanized and automated functions were introduced, such as manual or electric lifting systems, and anti-slip and safety protection devices. Publication No.: CN204916082U discloses a new type of boarding safety gangway, characterized in that it consists of a gangway main body, a gangway lifting mechanism, a gangway recovery mechanism, an integral moving mechanism, and a gangway inclination angle compensation adjustment mechanism. One end of the gangway main body is placed at the dock end through the integral moving mechanism, and the other end of the gangway main body is erected on the hull deck through the gangway inclination angle compensation adjustment mechanism. The gangway main body is controlled to be pulled by a steel wire rope provided in the gangway lifting mechanism, and the gangway main body is recovered by the gangway recovery mechanism. Made of all-aluminum alloy, it has low material density, light weight, high strength, good anti-corrosion performance, and is suitable for marine climate. It has a compact structure, is highly integrated, and is easy and quick to connect. It is not troubled by strong winds and waves, ebbs and flows, and can adapt to various harsh environments. It has high safety performance, and personnel can move up and down freely with loads at any tide level and any angle. However, as for the above-mentioned boarding ladder, the ladder cannot be raised or lowered. When the ship docks, the ship can only dock at a dock at a specific height, which limits the scope of application of the ship. At the same time, the boarding ladder that cannot adjust the height may affect the operating efficiency of the ship, resulting in an increase in berthing time and an increase in the operating cost of the ship, which needs to be improved.
