The invention provides a lifting and jacking integrated crown block system. The lifting and jacking integrated crown block system comprises a lifting crown block frame body, a continuous climbing mechanism, a lifting frame body and a lifting appliance, the hoisting crane frame body is arranged on a main truss of the self-climbing crane and moves in the transverse bridge direction; the continuous climbing mechanism is arranged on the hoisting crown block frame body and used for lifting the hoisting crown block frame body in the vertical direction; the hoisting frame body is arranged on the hoisting crane frame body and can move in the length direction of the hoisting crane frame body, the hoisting tool is used for hoisting a bridge structure to be installed, the hoisting tool is connected with the hoisting frame body through a steel wire rope, and the hoisting frame body guides the steel wire rope for hoisting the hoisting tool. According to the lifting and jacking integrated crown block system, self-climbing of the lifting and jacking integrated crown block system is achieved through insertion matching between the lifting stand column and the climbing oil cylinder in the continuous climbing mechanism, the main truss connected with the lifting and jacking integrated crown block system is driven to climb, a crane does not need to be lifted through a tower crane attached to a tower column, and construction is convenient.
本申请提供一种起重顶升一体式天车系统,包括起重天车架体、连续爬升机构、起吊架体及吊具;起重天车架体设于自爬升起重机的主桁架上,并沿横桥向移动;连续爬升机构设于所述起重天车架体上,以用于沿竖直方向提升起重天车架体;起吊架体设于起重天车架体上,且可沿起重天车架体的长度方向移动,吊具用于吊装待安装的桥梁构筑物,吊具与起吊架体之间通过钢丝绳连接,且起吊架体对起吊吊具的钢丝绳进行导向。通过连续爬升机构中的升降立柱及爬升油缸之间的插接配合,来实现起重顶升一体式天车系统的自爬升,并带动与起重顶升一体式天车系统连接的主桁架的爬升,无需使用附着塔柱的塔吊来提升起重机,施工方便。
