The invention discloses a lifting device for steel box girder construction and a construction method thereof, and relates to the technical field of building construction.The lifting device comprises a lifting appliance, the lifting appliance is fixedly connected with a lifting rope of an external crane, the bottom of the lifting appliance is fixedly connected with a double-shaft motor, output shafts at the two ends of the double-shaft motor are fixedly connected with lead screws, and threaded sleeves are in threaded connection with the interiors of the lead screws; the side wall of the threaded sleeve slidably penetrates through the inner side wall of the lifting appliance and is fixedly connected with the side wall of the end, away from the lifting appliance, of the first unfolding frame, the two sets of distance sensors can sense the distance between the steel box girders below the two sets of distance sensors, and whether the steel box girders are parallel to the lifting appliance or not is judged by sensing whether the distance between the steel box girders is different or not. Then the servo motor is controlled to drive the lead screw to rotate, the lead screw drives the sliding sleeves to adjust the height, and the four sliding sleeves can drive the four hooks to adjust the height of the four corners of the steel box girder, so that the steel box girder and the lifting appliance are adjusted to be arranged in parallel, and follow-up installation is facilitated.
本发明公开了一种钢箱梁施工用的吊装装置及其工法,涉及建筑施工技术领域,包括吊具,吊具与外部吊车的吊绳固定连接,吊具底部固定连接有双轴电机,双轴电机两端输出轴均固定连接有丝杆,丝杆内螺纹连接有螺纹套,且螺纹套侧壁滑动穿过吊具内侧壁与第一展开架远离吊具的一端侧壁固定连接,两组距离传感器并可感应与下方钢箱梁之间和之间的距离,并通过感应钢箱梁之间和之间距离是否有差别,并以此来判断钢箱梁是否与吊具平行,随后控制伺服电机带动丝杆转动,丝杆带动滑动套调节高度,四组滑动套并可带动四组挂钩调节钢箱梁四角的高度,以便于调节钢箱梁与吊具平行设置便于后续的安装。
