Multifunctional deck crane for middle cable plane cable-stayed bridge
The invention discloses a multifunctional deck crane for a middle cable plane cable-stayed bridge. Comprising a main truss, a lifting system, a walking walking mechanism, a supporting anchoring system, a stay cable hoisting system, a rear anchoring system and a lifting appliance. Before the bridge deck crane hangs a beam, the two stay cables can be hung on the stay cable hoisting mechanism on the bridge deck crane. When the bridge deck crane hoists the steel beams in place and completes welding of the steel beams, the bridge deck crane drives the stay cables to walk to the hoisting position of the next steel beam, then the stay cable hoisting mechanism starts to work, and the sliding cross beam on the upper portion is driven by an oil cylinder so that the sliding cross beam can move in the bridge direction. The transverse moving mechanism adopts screw transmission, and a sliding support can slide in the transverse bridge direction by manually rotating a screw in the horizontal direction. The jacking mechanism is also in spiral transmission, and the height position of the stay cable can be adjusted by rotating a screw rod in the vertical direction, so that the stay cable enters a mounting position. And then a pin shaft is mounted to fix the stay cable on the anchor pulling plate of the steel beam. The installation of the steel beam is completed, and the hoisting of the next steel beam can be started.
本发明公开了一种用于中索面斜拉桥上多功能的桥面吊机；包括主桁架、起升系统、步履走行机构、支撑锚固系、斜拉索吊装系统、后锚系统以及吊具。本桥面吊机在吊梁前，可以将两根斜拉索挂装到桥面吊机上的斜拉索吊装机构上。当桥面吊机将钢梁吊装到位且完成钢梁焊接后，桥面吊机带动斜拉索走行到下一片钢梁吊装位置，并将后其斜拉索吊装机构开始工作，上部的滑移横梁使用油缸驱动，能使滑移横梁顺桥向移动。横移机构使用螺旋传动，通过手动转动水平方向螺杆，使滑动支座能横桥向滑动。顶升机构也为螺旋传动，通过转动竖直方向的螺杆能使斜拉索的高度位置进行调整，使斜拉索进入安装位置。然后安装销轴将斜拉索固定到钢梁的拉锚板上。这片钢梁的安装就全部完成，可以开始下一片钢梁的吊装。
