Wind power blade transport cart of improved turnover plate mechanism

Abstract

The invention discloses a wind power blade transport cart of an improved turnover plate mechanism. The wind power blade transport cart comprises a main beam, an L-beam turnover plate, a hinge part and a lifting mechanism; the L-beam turnover plate comprises a horizontal section and a vertical section, the horizontal section and the vertical section of the L-beam turnover plate are provided with a connecting part, and a turnover plate balance weight is arranged on the vertical section of the L-beam turnover plate; the two ends of the lifting mechanism are connected with the main beam and the L-beam turnover plate respectively, the lifting mechanism is arranged vertically or slantly relative to the main beam, the lower surface of the horizontal section of the L-beam turnover plate is in contact with the upper surface of the main beam, and the L-beam turnover plate is connected with the main beam through the hinge part; and a certain distance is reserved between the hinge part and the connecting part of the horizontal section and the vertical section of the L-beam turnover plate. A hinged support of the wind power blade transport cart is forwards moved relative to a traditional tool supporting point and is not located under the vertical section of the L-beam turnover plate, a certain distance is reserved between the hinged support and the position under the vertical section of the L-beam turnover plate, and the distance between the hinged support and the turnover plate balance weight is obviously increased; and when lifting is carried out, jacking can be completed only through the turnover plate balance weight with small weight, energy sources are saved, and the balance and the 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...
