Self-adaptive fine adjustment folding method for steel truss girder
The invention discloses a self-adaptive fine adjustment folding method for a steel truss girder. The method comprises the following steps that S1, point cloud information of rod pieces at the two ends is scanned under the same folding temperature condition; a target spot is arranged on the rod piece; according to the point cloud information, obtaining a first relational expression reflecting a target spot, a plug group and a centroid relationship; s2, measuring coordinates of a target point of the rod piece; obtaining the deviation between the rod pieces at the two ends according to the target point coordinates and a first relational expression; adjusting the positions of the rod pieces according to the deviation until the frames at the two ends are basically consistent; s3, any end is fixed as a fixed end, and the other end is a free end; measuring the centroid relative position relation between the rod pieces at the same end and the target coordinates of the free end and the fixed end, and obtaining the target increment of the free end in combination with the first relational expression; and S4, adjusting the free end according to the target increment of the free end to complete folding of the two ends.
本发明公开了一种钢桁梁自适应精调合拢方法，包括以下步骤：S1、在合拢同温条件下扫描两端杆件的点云信息；在杆件上设置靶点；根据所述点云信息得到体现靶点、栓群和形心关系的第一关系式；S2、测量杆件靶点坐标；根据所述靶点坐标和第一关系式得到两端杆件间的偏差；根据所述偏差调整杆件位置至两端框架基本一致；S3、将任一端固定为固定端，另一端为自由端；测量同端杆件间形心相对位置关系、自由端及固定端靶点坐标，结合第一关系式得到自由端靶点增量；S4、根据所述自由端靶点增量对自由端进行调整，完成两端合拢。
