Precise three-dimensional positioning device and method for hoisting and closure of steel box girder
The invention discloses a precise three-dimensional positioning device and method for hoisting and closure of a steel box girder. According to the technical scheme, the device comprises an adsorption component, a transverse moving assembly, a longitudinal moving assembly and a lifting assembly, and the adsorption component is used for stably fixing the device to a steel box girder; the transverse moving assembly is fixed above the adsorption part and comprises a base and a transverse pushing jack installed on one side of the base. The longitudinal moving assembly comprises a positioning support connected with the transverse pushing jack and connected with the base in a sliding mode, and the longitudinal pushing jack is installed on one side of the positioning support. The lifting assembly comprises a lifting beam connected with the positioning support in a sliding mode, a center hole jack is installed at the end of the lifting beam, and the center hole jack is detachably connected with a butt joint lug plate used for fixing the closure section steel box girder. The transverse, longitudinal and vertical three-dimensional positioning functions of the steel box girder are integrated, the problems that the steel box girder is difficult to position and close accurately, and a large number of positioning stacking plates need to be welded can be solved at the same time, positioning is accurate, and repeated use can be achieved.
本发明公开了一种钢箱梁吊装合龙精准三维定位装置及方法，其技术方案为：包括吸附部件、横向移动组件、纵向移动组件和升降组件，吸附部件用于将装置稳定固定在钢箱梁上；横向移动组件固定于吸附部件上方，包括底座和安装于底座一侧的横推千斤顶；纵向移动组件包括与横推千斤顶相连、并与底座滑动连接的定位支座，所述定位支座一侧安装纵推千斤顶；升降组件包括与定位支座滑动连接的提升梁，所述提升梁端部安装穿心千斤顶，穿心千斤顶与用于固定合龙段钢箱梁的对接耳板可拆卸连接。本发明将钢箱梁横向、纵向和竖向三维定位功能集成为一体，可以同时解决钢箱梁难以精确定位合龙、需要大量焊接定位码板的问题，定位准确、可重复使用。
