The invention discloses a rapid positioning method and device for hoisting of a steel box girder, and relates to the field of steel box girder installing.The device comprises a crane, a fixing plate is installed at one end of the crane, and a supporting column is installed on one side of the fixing plate. According to the device, a hydraulic cylinder works to drive a first fixing rod to move, two second rotating rods rotate along with the first fixing rod, the distance between a first moving plate and a second moving plate can be conveniently adjusted, the steel box girder transversely moves towards the side edge of the embedded part, a positioning block is pushed, the positioning block moves towards a first connecting plate, a spring is compressed, and a laser receiver moves along with the steel box girder; after the embedded part makes contact with the steel box girder, the end of the positioning block abuts against the outer side of the first clamping plate, at the moment, the laser receiver can receive light rays emitted by the laser emitter, the controller receives signals and displays that the position of the steel box girder is installed correctly, the steel box girder can be rapidly positioned conveniently, and the positioning precision of the steel box girder is improved.
本发明公开了一种钢箱梁吊装快速定位方法及装置,涉及钢箱梁安装领域,包括吊车,所述吊车的一端安装有固定板,所述固定板的一侧安装有支撑柱。本发明中,通过液压缸工作带动第一固定杆移动,两个第二转动杆随之转动,便于对第一移动板和第二移动板之间的距离进行调节,使得钢箱梁横向朝预埋件的侧边处移动,定位块被推动,向第一连接板处移动,弹簧压缩,激光接收器随之移动,在预埋件与钢箱梁接触后,定位块的端部抵在第一夹持板的外侧,此时的激光接收器可接收激光发射器发射的光线,则控制器收到信号,显示钢箱梁的位置安装正确,便于对钢箱梁进行快速定位,提高钢箱梁定位的精度。
