The invention provides a special lifting appliance for a high-speed railway prefabricated box girder reinforcing mesh and a lifting method, and the special lifting appliance comprises an upper lifting beam, a lower lifting beam, a lower lifting beam, an upper lifting beam and a lower lifting beam, wing beams are correspondingly hinged to the two sides of the middle hanging beam in the width direction; the lower lifting beam is located below the middle lifting beam, the width of the lower lifting beam is smaller than that of the middle lifting beam, and the lower lifting beam is connected to the upper lifting beam through a lifting driving piece; and the plurality of claws are correspondingly distributed on the middle hanging beam, the wing beams and the lower hanging beam so as to hang and take the reinforcing mesh. The railway prefabricated box girder reinforcement cage is decomposed into a plurality of reinforcement meshes and a plurality of steel belt meshes, the reinforcement meshes and the steel belt meshes are hoisted through the middle hoisting beam, the lower hoisting beam and the wing beams, and mechanical intelligent component mesh machining, automatic splicing, mechanical manual replacement and automatic manual reduction are achieved. And the bridge box girder reinforcement cage is automatically assembled.
本发明提供一种高速铁路预制箱梁钢筋网专用吊具及吊运方法,包括:上吊梁,上吊梁上设有两个吊耳,用于连接起重设备进行起吊;中吊梁,中吊梁宽度方向的两侧对应铰接有翼梁;下吊梁,下吊梁位于中吊梁下方,其宽度小于中吊梁,并通过升降驱动件连接在上吊梁上;钩爪,多个钩爪对应分布在中吊梁、翼梁和下吊梁上,以挂取钢筋网片。将铁路预制箱梁钢筋骨架分解成多个钢筋网和多个钢带网,通过中吊梁、下吊梁和翼梁进行吊运,实现机械智能化部品网片加工、自动化拼装,机械化换人、自动化减人,通过本申请的专用吊具形成铁路预制箱梁钢筋骨架装配式建造生产线,进行桥梁箱梁钢筋骨架的自动化拼装。
