Large scale wind wheel blade static test of the multi point load side pull test device

A large scale wind wheel blade static test of the multi point load side pull test device is used to fasten the blade to be tested with a fastening base parallel to the ground. On one side of the blade, a plurality of side-pull supporting frames is provided perpendicular to the ground. The number of side-pull supporting frame distributed is corresponding to the number of loading points of the blade. At least one power device is provided. The power device offers static force to the phased testing portions via a number of side-pull supporting frames. The height of the fixed pulley on the side-pull supporting frame can be adjusted according to the height of loading point of the blade. The position of side-pull supporting frame can be flexibly moved according to the loading positions of the blade. This utility model is suitable for testing blades of different sizes. The loading position of the blade and the fixed pulley is at the same horizontal level, so that the force loaded onto the loading point of the blade via drawing ropes remain in the horizontal direction, and true and reasonable testing data can be obtained and effect of multi-point loading static testing can be realized.
