A wind turbine blade transport vehicle with an improved flap mechanism

Abstract

The invention discloses a wind power blade transport vehicle with an improved flap mechanism, which includes a main beam, an L beam flap, a hinge part, and a lifting mechanism. The L beam flap includes a horizontal section and a vertical section, and the L beam flap has a horizontal section. There is a connecting part with the vertical section, and the vertical section of the L beam flap is provided with a flap counterweight. The two ends of the lifting mechanism are respectively connected with the main beam and the L beam flap, and are vertically or inclined relative to the main beam. The L beam The lower surface of the horizontal section of the flap is in contact with the upper surface of the main beam, and is connected to the main beam through a hinge. The position of the hinge is: a certain distance away from the connection between the horizontal section and the vertical section of the L beam flap. The fulcrum of the tooling moves forward, not directly below the vertical section of the L-beam flap, but away from it for a certain distance, and the distance from the flap counterweight is significantly increased. When lifting, only the weight of the flap counterweight with a small weight is required Lifting can be completed, energy is saved, and balance and safety are improved.

Description

technical field [0001] The invention relates to a transportation device, in particular to a wind turbine blade transportation vehicle with an improved turnover mechanism. Background technique [0002] With the country's vigorous development of clean energy, the development and utilization of clean energy is becoming more and more common. Among them, wind energy has received special attention, wind power generation has been rapidly promoted, and high-power wind turbines have appeared, but the size of wind turbine blades They are all relatively large. Taking a 2.5MW wind turbine as an example, the blade itself is 45.3 meters long, 2.5 meters in diameter, and weighs 10 tons. According to the distribution of wind resources in my country, most wind farms are located in plateau mountainous areas with complex terrain. , the road grade is low, the mountain is high and the slope is steep, and the road is rough. When the wind turbine blade transportation equipment is in use, it needs to...
