Replacement device and force system conversion control method for special-shaped arch bridge space curved surface sling
The invention discloses a replacement device and a force system conversion control method for a spatial curved surface sling of a special-shaped arch bridge, and the device comprises a vertical plane, a first clamp, a second clamp, a lower joist, a first temporary suspender, a second temporary suspender, a first tensioning device, a second tensioning device, a third tensioning device, an inclination angle detection device and a cable force detection device, wherein the vertical plane is the plane where the sling axis is to be replaced and is perpendicular to the cross section of the special-shaped arch where the sling axis is located, and the lower joist is installed on the intersecting line of the vertical plane and the bottom face of the cross beam. According to the replacing device for the spatial curved surface sling of the special-shaped arch bridge and the force system conversion control method, the first tensioning device and the second tensioning device can be driven according to the out-of-plane deflection angle of the vertical plane and the cable force value of the sling to be replaced through hierarchical synchronous unloading, and out-of-plane component force is controlled to be always balanced and equal; and the special-shaped arch structure is prevented from inclining outwards.
本发明公开了一种用于异型拱桥空间曲面吊索的更换装置及力系转换控制方法，该装置包括：竖直平面、第一夹具、第二夹具、下托梁、第一临时吊杆、第二临时吊杆、第一张拉装置、第二张拉装置、第三张拉装置、倾角检测装置、索力检测装置，其中竖直平面待更换吊索轴线所在平面、且与该吊索轴线所在位置的异型拱横断面垂直，下托梁安装于竖直平面与横梁底面的相交线上。本发明公开的一种用于异型拱桥空间曲面吊索的更换装置及力系转换控制方法，可根据竖直平面面外偏斜角度和分级同步卸载待更换吊索索力值驱动第一张拉装置和第二张拉装置，控制面外分力始终均衡相等，防止异型拱结构向面外倾斜。
