大型钢结构件焊接过程中需要翻转,由于结构件超大、超重,普通桁吊起吊吨位受限而难以完成翻转过程,即使完成也会对地面造成较大的损坏和增加危险性。通过配备专用弧形翻转装置、焊接角度支撑装置,变滑动摩擦为滚动摩擦,侧滑力为向下的压力,并对关键部件弧形翻转装置进行了有限元分析,有效解决了普通桁吊以小吨位完成超大、超重结构件的翻转问题。 Large-scale structural steel parts need to be turned over during the welding process. Due to the oversize, overweight and ordinary tonnage hanging crane, the overturning process is difficult to complete, which will cause great damage and increase the danger to the ground even if completed. Through the special arc-shaped turning device, the welding angle support device, the variable sliding friction is the rolling friction, the sliding force is the downward pressure, and the finite element analysis is performed on the arc-shaped turning device of the key components, which effectively solves the problem of the common truss hanging Small tonnage to complete oversized, overweight structural parts of the flip problem.
