Problems solved by technology

[0003] The existing A-type gantry mainly performs simple heave and wave compensation through the supporting constant tension winch and the retraction and release of the suspension cable, so most of them can only be operated in low sea conditions, which cannot meet the production work needs of people in high sea conditions; There are also some A-type gantry mounts with anti-swing buffer devices on the beams, but they are passive wave compensation, with obvious hysteresis and poor precision, and these devices have a large mass, which increases the load of the system

Abstract

The invention relates to a wave-compensating marine A-type gate crane foundation arranged on the side of a hull and comprising a base, a telescopic frame and a cross beam; the telescopic frame is arranged on the upper surface at one end of the base; an attitude sensor is also arranged on the upper surface of the base; the telescopic frame includes two rockers hinged to the base and symmetrically arranged on two sides of the base, and a moving rack is nested in an inner cavity at the other end of each rocker; the cross beam is connected with the moving racks at the ends far away from rockers; the cross beam is also provided with a connector hanger. The wave-compensating marine A-type gate crane foundation also comprises servo driving mechanism A that drives the moving racks to expand alongthe rockers, servo driving mechanism B that drives the telescopic frame to rock, and servo driving mechanism C that drives the connector hanger to transversely move along the cross beam. The wave-compensating marine A-type gate crane foundation has the advantages that the foundation helps hoist and reclaim equipment safely and stably under terrible sea condition.

Description

technical field [0001] The invention belongs to the technical field of ship engineering, and relates to an A-type gantry for offshore ships, in particular to an A-type gantry base for a wave compensation ship. Background technique [0002] All kinds of unmanned submersibles are important tools for human beings to develop the ocean. As an important supporting equipment, the lifting system plays a decisive role in the efficiency of ocean operations. At present, the application of various retractable systems for offshore ships has become very popular, and the most typical lifting device is the A-type gantry. [0003] The existing A-type gantry mainly performs simple heave and wave compensation through the supporting constant tension winch and the retraction and release of the suspension cable, so most of them can only be operated in low sea conditions, which cannot meet the production work needs of people in high sea conditions; There are also some A-type gantry mounts with an...
