Wind power type offshore embarkation walking bridge

Abstract

The invention relates to a wind power type offshore embarkation walking bridge, and belongs to the technical field of offshore operation and maintenance bridge ladder equipment. A walking bridge base,a cylindrical shell and a conical shell are arranged; the cylindrical shell is located on a rotary base of a motion compensation platform; the conical shell is connected with a rotary cantilever crane through a second rotary base; a hanging lug is arranged at the top end of the conical shell and connected with a hydraulic oil cylinder so as to be connected with a bridge ladder to control pitchingof the bridge ladder. A console and a control cabinet are arranged in the cylindrical shell and the conical shell; the equipment structure can be effectively simplified to reduce the structure weight, and a force transmission mode is optimized; various devices and operation and maintenance personnel in the cylindrical shell and the conical shell are effectively protected; personnel and materialsneeding to be conveyed on the sea surface can be rapidly and safely transferred for multiple times under a sea condition with large stormy waves, the manufacturing and maintenance cost is greatly reduced, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of offshore operation and maintenance bridge ladder equipment, and particularly relates to a wind power type offshore boarding bridge. Background technique [0002] As we all know, the ocean occupies more than 70% of the earth's surface, and various countries attach great importance to the development and utilization of the ocean. [0003] However, whether it is maritime transportation or maritime operations, there are certain risks, including waves, typhoons, tides, etc., maritime vessels and offshore operation platforms will always be in a danger, for the safe transfer of their personnel and materials and rapid The transfer will be very demanding. [0004] At present, most of the equipment for boarding operations at sea has few degrees of freedom and cannot solve the change in the distance between the ship and the fixed structures at sea caused by the action of waves and tides. The application in high sea...

AI Technical Summary

Problems solved by technology

[0003] However, whether it is marine transportation or offshore operations, there are certain dangers, including waves, typhoons, tides, etc., and offshore vessels and offshore operating platforms will always be in danger. For the safe transfer of personnel and materials and the rapid Transfers will have high requirements

[0004] At present, most of the equipment used for sea boarding operations has less freedom, which cannot solve the distance change between the ship and the fixed structure at sea under the action of waves and tides, and its application is very limited in high sea conditions; most of the gangways are non-rotating. The pitch cannot be adjusted actively; some transfer platforms for landing operations are too large, the structural stress state and force transmission process are complex, and the pitching cylinder requires greater pulling force, which will increase the cost; cargo transportation cannot be realized multiple times at sea Fast conveying operations; and most of the hydraulic drive equipment, electrical consoles, control cabinets, etc. are placed in the open air, with high protection requirements and are susceptible to salt and fog corrosion, which indirectly increases the cost of operation and maintenance and rescue, and the efficiency is very low
