China has abundant wind energy resources, and the development space of wind power generation in China is huge. The main equipment of wind power generation is a wind turbine generator, and the wind turbine generator has the characteristics of large size (the diameter of a fan blade wheel is more than 140 meters), heavy equipment (the weight of an engine room is more than 70 tons) and large height (the height of a fan tower barrel is more than 90 meters), so that the transportation and installation of the wind turbine generator in the construction of wind power engineering are important difficult points. The transportation of the wind power equipment mainly depends on the existing road network outside the wind farm and the newly built road in the wind farm. The installation mainly depends on hoisting equipment to hoist and install in the hoisting place.
The wind turbine generator hoisting scheme is divided into two modes of assembling three blades on the ground, hoisting the whole impeller at high altitude, assembling the three blades on the ground or assembling two blades, and finally hoisting a single blade at high altitude according to the assembling sequence of the fan blades. The hoisting mode of the blade ground assembly is simple in process and low in assembly cost, but the hoisting platform is required to have the size enough for assembling the blade, and the earth surface obstacle in the range of the blade is located. The hoisting process for high-altitude assembly of the blades is complex, the requirement on the size of a hoisting platform is relatively low, the cost is high, and the construction progress is often influenced by weather.
In actual engineering, in order to guarantee the construction progress, the wind power engineering is carried out the fan blade and then is lifted by crane at the wheel hub height position after assembling on ground for many choices, but this kind of hoisting platform size often is great, and needs to clear up the earth's surface attachment in near hoisting platform blade sweep-out range.
