Embodiment

[0019] see figure 1 A turning device for wind power generation blades comprises a horizontal ground 1 , a ground groove 2 and a blade 3 . In order to prevent the blade 3 from colliding with the ground groove 2, the ground groove 2 is a cuboid with a length of 80 meters, a width of 12 meters and a depth of 1 meter.

[0020] see figure 2 and image 3 , the turning device also includes a base 4, several anchor screws 5, a motor 6, a pin shaft (not shown in the figure), a transmission shaft 7, a chuck 8, a mandrel (not shown in the figure show). The base 4 is fixed on the right end of the horizontal ground 1 by several anchor screws 5 to prevent the base 4 from moving. The motor 6 is placed on the base 4, the motor 6 is connected to the transmission shaft 7 through the pin shaft, the transmission shaft 7 is rotationally connected to the chuck 8, and the chuck 8 passes through the The mandrel is engaged with the tail portion 31 of the blade 3 , and the centerline of the chuck...

Abstract

The invention discloses a turnover device for a wind turbine blade. The turnover device for the wind turbine blade comprises an operating platform and a base with a motor; the operating platform comprises a groove which is used for accommodating the wind turbine blade; the motor is in rotary connection with a tail portion of the wind turbine blade; a chuck comprises a mandrel which is used for being snapped to the wind turbine blade. The turnover device for the wind turbine blade has the advantages of solving the problem that the wind turbine blade is difficult to turn over, being simple in structure, easy to operate, low in manufacturing costs, greatly reducing labor costs and improving the working efficiency.

Description

technical field [0001] The invention relates to a turning device for wind power generation blades, in particular to a turning device for wind power generation large megawatt blades. Background technique [0002] The length of the blades of wind turbines varies according to the power. The 3 MW blades are 58 meters long, the 5 MW blades are 68 meters long, the 6 MW blades are 75 meters long, and the maximum chord length of the blades is 4 to 8 meters. , when the blade is painted, polished, etc., it is difficult to turn over due to the large volume of the blade, which is time-consuming and laborious, and is very inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a turning device for wind power generation blades in order to overcome the time-consuming, laborious and difficult defects of turning over wind power generation blades in the prior art. [0004] The present invention solves the above technical pr...
