Detailed Description
The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.
As shown in fig. 1. The utility model provides a rotatable boarding manway, which comprises a support and a straight ladder 14, wherein one end of the straight ladder 14 is hinged to the top end of the support, the connecting end of the support and the straight ladder 14 is higher than a fence of an offshore wind power installation platform, two sides of the support and the straight ladder 14 are respectively provided with a handrail 2 and a safety handrail 6, a connecting chain 4 is arranged between the handrail 2 and the safety handrail 6, the bottom of the support is provided with a support roller 1, and the support and the straight ladder 14 are connected through a steering hinge 8.
The support is in a triangular structure, the stepping 3 is arranged on the inclined plane of the support, the lug plate is arranged at the top of the support, and the lug plate and the steering hinge 8 are used for rotationally connecting the end part of the vertical ladder 14, so that the vertical ladder 14 is stably connected to the support. The support is moved to the stern of the offshore wind power platform through the support roller 1, so that the straight ladder 14 spans across the rail of the offshore wind power installation platform, and then the movable end of the straight ladder 14 is placed on the base platform 13 on the fan jacket 12, so that the connection between the offshore wind power installation platform and the fan working platform is realized, and a constructor can enter the fan working platform.
