The invention relates to a hoisting device for dismantling an overpass railway hollow slab beam and a using method, and belongs to the technical field of bridge construction. The device comprises at least two hoisting devices, each hoisting device comprises a set of brackets and a set of upper hoisting frames, and the two brackets are arranged in a spaced mode and used for supporting a hoisted object; the upper hanging brackets are arranged above the bracket at intervals, the two sides of each upper hanging bracket are connected with the two sides of the bracket through steel plates to form a U-shaped structure, and a limiting frame is arranged between the two hoisting devices. When the overpass railway hollow slab girder is dismantled, the two sides of each set of upper hanging bracket and the two sides of the bracket are connected through steel plates, the bracket is arranged at the bottom end of a hoisted object, the upper hanging bracket is located at the top end of the hoisted object, the hoisting equipment is connected to the upper hanging bracket, and the hoisted object is hoisted through the upper hanging bracket to be dismantled. And the limiting frame is connected between the two hoisting devices and is used for limiting the upper hoisting frame, so that the upper hoisting frame is prevented from sliding towards the longitudinal bridge, and the hoisting construction reliability is ensured.
本申请涉及一种上跨铁路空心板梁拆除用吊装装置及使用方法,属于桥梁施工技术领域。本申请的装置包括至少两个吊装装置,每个所述吊装装置包括一组托架和一组上吊架,两个托架之间间隔设置,用于托起被吊物;上吊架间隔设置于托架上方,且上吊架两侧与托架两侧均通过钢板进行连接,形成“U”形结构,且两个吊装装置之间设置有限位架。在对上跨铁路空心板梁的拆除中,将每组上吊架两侧和托架两侧通过钢板进行连接,托架设置于被吊物的底端,上吊架位于被吊物的顶端,吊装设备连接于上吊架,通过上吊架将被吊物吊起,进行拆除。两个吊装装置之间连接设置有限位架,对上吊架进行限位,防止上吊架朝纵桥方向滑移,保证吊装施工的可靠性。
