Inhaul cable device for whole-hole span-by-span construction of reinforced concrete composite beam
The invention discloses an inhaul cable device for whole-hole span-by-span construction of a reinforced concrete composite beam, and belongs to the technical field of bridge construction. The inhaul cable device comprises a pier, a beam box is erected at the top end of the pier through a bridge girder erection machine, and at least three groups of inhaul cable mechanisms for pulling flanges at thetwo sides of the top end of the beam box are arranged on a cross beam of the bridge girder erection machine; and each inhaul cable mechanism comprises a winding device with a rope and a hook connected with the free end of the rope through a connecting block, and limiting mechanisms for positioning the hooks are arranged at the bottom end of the cross beam of the bridge girder erection machine. According to the inhaul cable device, the telescopic ends of hydraulic air cylinders are rotationally connected with the connecting blocks at the hooks on the inhaul cable mechanisms, so that the hydraulic air cylinders located at the two sides of the hooks can limit the hooks on the ropes during winding and unwinding, it is guaranteed that the hooks cannot swing drastically during vertical positionadjustment, and connection between the hooks and hanging rings is facilitated; and meanwhile, it is guaranteed that the beam box cannot be staggered on the pier in the horizontal direction, and the traction effect of the inhaul cable mechanism is improved.
本发明公开了一种用于钢混组合梁整孔逐跨施工的拉索装置，属于桥梁施工技术领域，包括桥墩，所述梁箱通过架桥机架设在桥墩的顶端，所述架桥机横梁上设有个数至少为三组且用于牵拉梁箱顶端两侧翼缘的拉索机构，所述拉索机构包括带有绳索的收卷装置、通过连接块与绳索自由端连接的挂钩，所述架桥机横梁的底端设有对挂钩进行定位的限位机构。本发明通过液压气缸伸缩端与拉索机构上挂钩处连接块的转动连接，使位于挂钩两侧的液压气缸可对收放卷时绳索上的挂钩进行限位，以保证挂钩在上下位置调整时不会大幅度摆动，以方便挂钩与挂环的连接，同时也保证了梁箱在桥墩上不会发生水平方向的错位，提高拉索机构的牵拉效果。
