Description

Technical Field

[0001] The utility model belongs to the technical field of wind power operation and maintenance equipment, and relates to a liftable horizontal telescopic station-boarding platform. Background Art

[0002] Wind power operation and maintenance refers to the work of daily maintenance, inspection and management of wind power generation equipment. The harsh offshore environment is one of the main challenges faced by offshore wind power operation and maintenance. Offshore wind farms are often located in areas with strong winds and high waves at sea. Affected by the marine climate, the environment is complex and changeable. In such a harsh environment, it is very difficult to carry out daily maintenance and inspection of wind power equipment. Strong winds and waves will cause the shaking and instability of offshore working vessels, affect the maintenance work, and even pose a threat to the safety of maintenance personnel. At the same time, offshore wind power equipment has been in the marine environment for a long time, and is corroded by seawater and impacted by waves, which is prone to mechanical wear, electrical failure and other problems. Once the equipment fails, it is often necessary to repair and repair it in a timely and effective manner to avoid further expansion of losses and affect the normal operation of the wind farm. Therefore, ensuring the safety and stability of offshore wind power operation and maintenance is a key link in the development of offshore wind power.

[0003] Ships or offshore platforms will experience large ups and downs under the action of waves. Among the six degrees of freedom in space, the heave, pitch and roll movements have the greatest impact on the staff. After using the wave compensation platform to compensate for the ship's movement, it cannot meet the changes in compensation height caused by changes in sea tide levels. For example, because the sea tide level rises, the height required for landing exceeds the height limit that the wave compensation platform can reach. The staff cannot land smoothly and need to mount a lifting platform on the wave compensation platform to compensate for the height difference. Utility Model Content
