Sliding pushing system of large-span navigation hole lifting trestle
The invention provides a sliding pushing system of a large-span navigable hole lifting trestle, which comprises a dragging sliding track arranged on the bridge surface of an original trestle on both sides of a river channel and used for supporting a bridge body frame to be pushed; the first power mechanism is used for providing power to enable the bridge body frame to move along the dragging and sliding rail, the first power mechanism comprises a winding device, a first fixed pulley, a movable pulley and a traction rope assembly, the winding device is arranged on the bridge surface of the original trestle, and the first fixed pulley is arranged on a first positioning structure fixed relative to the dragging and sliding rail; the traction rope assembly comprises a first traction rope and a second traction rope; the first traction rope is connected between the movable pulley and the bridge body frame; one end of the second traction rope is connected to a reel of the winding device, the other end of the second traction rope is connected to the first positioning structure, and the second traction rope is sequentially matched with the pulley of the movable pulley and the pulley of the first fixed pulley. According to the construction scheme, participation of large hoisting equipment is reduced, and efficiency is high.
本发明提供一种大跨径通航孔提升栈桥的滑移顶推系统，包括：拖拉滑移轨道，设置于河道两岸的原栈桥的桥面上，用于支撑待顶推的桥体框架；第一动力机构，用于提供动力使桥体框架沿拖拉滑移轨道移动，第一动力机构包括卷扬装置、第一定滑车、动滑车以及牵引绳组件，卷扬装置设置于原栈桥的桥面，第一定滑车设置于与拖拉滑移轨道相对固定的第一定位结构上；牵引绳组件包括第一牵引绳和第二牵引绳；第一牵引绳连接于动滑车与桥体框架之间；第二牵引绳的一端连接于卷扬装置的卷轴，另一端连接于第一定位结构，且第二牵引绳依次配合于动滑车的滑轮以及第一定滑车的滑轮。本发明实现一种减少大型吊装设备参与且效率较高的施工方案。
