Abstract

The invention provides a boarding device for an offshore wind power draught fan. The boarding device comprises a foundation assembly and a tripod, wherein the foundation assembly is arranged on a main deck of a ship; the tripod is arranged on a draught fan bearing platform; the foundation assembly is connected with the tripod through a gangway ladder; the foundation assembly comprises a drum body with an opening at the top; a spherical part of a ball turntable is arranged at the top of the drum body and is supported through a four-point contact bearing; a plane gland is connected with the upper part of the ball turntable; a pedal is arranged on the upper part of the plane gland and can be rotated around a bearing on the plane gland; a counterweight is arranged in the drum body; the top of the counterweight is fixed together with the lowest point of the spherical part of the ball turntable. When a ship swings, the drum body swings following the ship; under an effect of counterweight, the plane gland is kept relatively horizontal, only four-point contact bearing slides along the spherical part of the ball turntable and the gangway ladder is kept relative stable. According to the device provided by the invention, the physical motion of a backswing mechanism is utilized to offset the bumping and swinging caused by huge stormy wave; when personnel use the boarding device for boarding the draught fan bearing platform, personnel has less possibility of being influenced by the stormy wave; the safety risk when the personnel go aboard is greatly reduced.

Description

technical field

[0001] The invention relates to a stage-mounting device for an offshore wind turbine, and belongs to the technical field of offshore berthing equipment. Background technique

[0002] At present, during the maintenance and emergency repair of offshore wind power equipment, the staff is usually sent from the transportation boat to the offshore machine stand, and boarded from the main deck of the boat to the wind turbine cap through the gangway (carrying tools and accessories at the same time). Due to the influence of uncertain factors such as sea wind and waves, the freedom of movement of the traffic boat is large, especially in the sea conditions with strong wind and waves, the up and down and left and right swings of the traffic boat are relatively large, and the bow of the boat is seriously deviated from the gangway of the fan cap. The head fluctuates violently, and it may even collide strongly with the wind turbine cap, causing a great safety hazard for the...
