Problems solved by technology

[0003] The utilization of offshore energy in existing technologies includes the use of offshore wind power towers for wind power generation operations and offshore oil platforms for oil exploration operations. However, after a period of operation of facilities and equipment such as offshore wind power towers and offshore oil platforms, parts need to be repaired, and even Replacement requires the use of ships to transport maintenance personnel and materials to offshore wind power towers or offshore oil platforms. The effect of tide and tide makes the distance between the ship and the fixed offshore structure change in several directions at any time. When the maintenance personnel board/leave the fixe

Abstract

The invention discloses a gangway bridge with rotating, pitching and extending-retracting functions, and belongs to the field of marine engineering. The problem that maintenance personnel of a marinefixed structure and materials needed for maintenance cannot be stably conveyed and transferred to a structure platform from an operation and maintenance ship is solved. The gangway bridge comprises arotating seat, a gangway bridge base, a fixed bridge ladder and a sliding bridge ladder; a rotating mechanism is mounted on the rotating seat; the gangway bridge base makes 360-degree rotating movement under the effect of the rotating mechanism; a pitching hydraulic oil cylinder is mounted on the upper end face of the gangway bridge base; the fixed bridge ladder is hinged to the gangway bridge base and connected with the pitching hydraulic oil cylinder, and the fixed bridge ladder makes vertical pitching movement under the effect of the pitching hydraulic oil cylinder; a gangway bridge telescopic transmission device is mounted at the bottom of the fixed bridge ladder; the sliding bridge ladder is sleeved with the fixed bridge ladder; and the sliding bridge ladder makes telescopic movementunder the effect of the gangway bridge telescopic transmission device. According to the gangway bridge, under the effect of the three degrees of freedom, the gangway bridge can be effectively overlapped to the marine structure, and thus the operation and maintenance personnel and the materials are safely and quickly conveyed.

Description

technical field [0001] The invention relates to a special step bridge for transporting personnel and materials between marine equipment, which belongs to the field of marine engineering. Background technique [0002] The vast sea contains rich resources, and there is truly inexhaustible marine energy. With the continuous advancement of science and technology, marine energy has received extensive attention and promotion from various countries. [0003] The utilization of offshore energy in existing technologies includes the use of offshore wind power towers for wind power generation operations and offshore oil platforms for oil exploration operations. However, after a period of operation of facilities and equipment such as offshore wind power towers and offshore oil platforms, parts need to be repaired, and even Replacement requires the use of ships to transport maintenance personnel and materials to offshore wind power towers or offshore oil platforms. The effect of tide an...
