The invention discloses a special lifting appliance for lifting a semi-direct-drive fan main engine, and relates to the technical field of lifting appliances, the special lifting appliance comprises a linear beam, one end of the linear beam is fixedly connected with a first connecting pair, and the other end of the linear beam is in bolted connection with a Y-shaped beam; the Y-shaped beam comprises a fixing rod, a fixing sleeve is nested in the side face of the fixing rod, rotating arms are rotationally connected to the two sides of the fixing sleeve, and a second connecting pair is fixedly connected to the ends, away from the fixing sleeve, of the rotating arms; the two groups of second connecting pairs are connected to one side of the Y-shaped beam, and are matched with the first connecting pair on one side of the linear beam to form three connecting points, so that the overall stability of the lifting appliance can be improved, the lifting appliance consisting of the linear beam and the Y-shaped beam can be completely attached to the structural form of a semi-direct-drive unit, and a double-eye circular lifting belt made of an ultra-high molecular weight polyethylene material can be used for lifting the semi-direct-drive unit. Compared with a traditional glass fiber sling, the glass fiber sling has the strong advantages of being light in self weight, convenient to install and convenient to transport.

    本发明公开了一种半直驱风机主机吊装专用吊具,涉及吊具技术领域,包括一字梁,一字梁的一端固定连接有第一连接副,一字梁的另一端螺栓连接有Y型梁;Y型梁包括固定杆,固定杆的侧面嵌套有固定套,固定套的两侧均转动连接有旋转臂,旋转臂远离固定套的一端固定连接有第二连接副;由于Y型梁这一侧连接有两组第二连接副,配合一字梁这一侧的第一连接副,具有三个连接点,这样可以提高吊具的整体稳定性,并且由一字梁和Y型梁组成的吊具会完全贴合半直驱机组的结构形式、超高分子量聚乙烯材质的双眼圆形吊带,对比传统的玻璃纤维吊带有着自重轻,安装便捷、便于运输的强大优势。
