The invention relates to a wind power blade single-web lifting appliance. The appliance comprises a fixing part and a clamping part, wherein the fixing part and the clamping part are connected to a support, wherein the fixing part is provided with a fixing end, the clamping part is provided with a free end, spacing between the fixed end and the free end can be adjusted until the spacing is smallerthan a thickness of a single web, the single web is lifted through frictional force and compaction force generated between the fixed end and the free end and the single web. A flange bonded part of the single web plate is not stressed during a lifting process, and the structural integrity of the single web can be ensured. The invention further relates to a wind power blade single-web lifting method. In the lifting process, only the free end needs to be adjusted, parts needing adjusting are few, an adjusting process is simple, so that the lifting process is fast and efficient.
本发明涉及一种风电叶片单腹板吊具,包括连接在支架上的固定部和夹持部,所述固定部具有固定端,夹持部具有自由端,固定端和自由端之间的间距可调节直至小于单腹板的厚度。利用固定端和自由端和单腹板之间产生的摩擦力和压紧力将单腹板起升吊运。单腹板在吊运过程中其粘结法兰部分不受力,能保证其结构完整性。还涉及风电叶片单腹板吊装方法,在吊运中仅需调节夹持部的自由端调节部件少并且调节过程简单,使得吊运过程快捷高效。
