Abstract

The invention discloses a three-degree-of-freedom offshore gallery bridge device with motion compensation capability, which comprises a telescopic gangway ladder and a three-degree-of-freedom stable platform, and the three-degree-of-freedom stable platform is movably connected below the telescopic gangway ladder. According to the device, three servo electric cylinders are adopted to control the pose of an upper stabilized platform of a three-degree-of-freedom stabilized platform in real time, and when a ship is subjected to complex disturbance generated by wind, wave and flow loads, main motion compensation control is carried out on an offshore gallery bridge device through real-time control over the three servo electric cylinders; so that the upper stable platform is kept in a horizontal state all the time, and then the gangway ladder is kept in the horizontal state, and therefore pose control over the offshore gallery bridge is achieved; furthermore a telescopic column is added on the three-degree-of-freedom stabilized platform for limiting torsion of the stabilized platform, rolling bearings are arranged on eight surfaces of the telescopic outer column and the telescopic inner column and are used for overcoming friction force generated in a platform movement process, so that the platform can quickly and stably operate.

Description

technical field [0001] The invention relates to the technical field of marine corridor bridge devices, in particular to a three-degree-of-freedom marine corridor bridge device with motion compensation capability. Background technique [0002] The development of marine engineering is inseparable from offshore platforms. Offshore drilling platforms can exploit and store oil and gas, and offshore wind power platforms can provide a large amount of wind energy. Offshore platforms need regular personnel maintenance and personnel replacement. The staff board the offshore platform and use the ship as a means of transportation. The situation at sea is more complex and changeable than that on land, and the hazards caused by severe weather are inevitable. In the process of transporting personnel and materials, high sea conditions generate wind, waves, and current disturbances, and collision accidents between ships and offshore platforms are prone to occur. In severe cases, the equipme...
