Novel static loading test device with distributive girder type structure for large-scale wind turbine blade

The utility model discloses a static loading test device with a distributive girder type structure for a large-scale wind turbine blade, which comprises distributive girders, fixed pulleys, a movable pulley and a winding rope which form a whole, wherein a pulley block comprising the fixed pulleys and the movable pulley is arranged on the distributive girder and takes place of a dowel bar in the prior device; resultant force loaded to the distributive girders is proportionally divided into two component force which are loaded to a loading point for testing a blade; the length of the distributive girder and the position of the loading point can be changed along with the distribution of the test load; and the arbitrary proportion distribution of the loading force is realized through increasing the number of the pulleys on the distributive girders. The device has the advantages that during the static loading process, not only the test load is distributed to all loading positions on the blade proportionally, the distributive girders are always in the horizontal position, and the loading force transmitted to the blade through the winding rope is always in the vertical upward direction to obtain reasonable and real testing data, so that the multi-point loading testing effect is achieved.
