Self-stabilizing ship gangway ladder system and control method

Abstract

The invention discloses a self-stabilizing ship gangway ladder system and a control method, and relates to the field of ship berthing gangway ladders. The self-stabilizing ship gangway ladder system comprises a six-degree-of-freedom hydraulic stabilizing platform, a gangway ladder stabilizing controller and a gangway ladder lifting and rotating mechanism. The six-degree-of-freedom hydraulic stabilizing platform comprises a platform stabilizing system. The platform stabilizing system comprises a hydraulic cylinder jacking system, a bearing platform, a PLC, a peripheral circuit, a servo signal amplification processing circuit and an electric servo system. The ship gangway ladder stability controller comprises a main control panel, a ship attitude signal collector and a serial port communication module; the ship attitude signal collector is used for collecting attitude change real-time values of a ship under the action of surges and wind power and sending data to the ship gangway ladder stability controller; and the gangway ladder lifting and rotating mechanism comprises a lifting motor, a rotating motor, a gear meshing device, a steel wire rope winding drum, a first lifting limiter,a second lifting limiter, a first rotating limiter and a second rotating limiter.

Description

technical field [0001] The invention relates to the field of ship berthing gangways, in particular to a self-stabilizing ship gangway system and a control method. Background technique [0002] After the berthing and mooring of large ships is completed, it is necessary to complete the erection of the disembarkation channel as soon as possible, so as to quickly open the passage for people from the wharf to the large ship. Generally, the tonnage of ships is small, and the boarding ladders for people from the wharf to the ship are generally brought by the ship and are responsible for setting up. However, the location of the boarding ladder for large-scale ships is special. The boarding ladder has a large horizontal span and a large number of people. The ship itself cannot carry and build the dock boarding ladder. Therefore, the port must be responsible for providing and building it. The erection and evacuation of passageways for personnel on large ships has become an important ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are several main types of ship gangways. The first type is a purely mechanical simple gangway without any electronic and hydraulic assistance. This type of gangway can only be applied to small ships and under very good sea conditions.

The second type is a gangway with a simple wire rope device, which can be lifted and rotated to complete two-dimensional connection operations. This gangway can adapt to small and medium-sized ships and general sea conditions below 6 / 7 winds. When encountering large ships and Working in bad weather is likely to cause damage to the travel motor and wire rope, and may cause personal safety injuries in severe cases

The third type of track-type gangway, this kind of gangway is composed of main parts such as walking mechanism, main frame, platform, driving mechanism, hydraulic control, floating ladder, etc. It is a little higher than the previous one to adapt to sea conditions and ship grades, but there is also a moving speed Disadvantages such as slowness and large footprint

The above various gangways cannot realize the collection of ship attitude, and the comparison of the current gangway attitude cannot realize multi-dimensional attitude adjustment in real time and quickly.
