The invention is applicable to the field of engineering machinery, and provides a replacement method for updating a tower crane, which comprises the following steps of: S1, stretching a cargo boom to a specified position along the horizontal direction, and calculating the moment M1 of a hoisted object to the center of a tower body; s2, calculating the theoretical distance between the balancing weight and the center of the tower body when the moment is balanced based on the moment M1; s3, the size relation of the theoretical distance and the distance data of the balancing weight and the center of the tower body is judged, and if the theoretical distance is larger than or smaller than the distance data, the step S4 is executed; s4, the moving direction of the balancing weight is set; and S5, moving the balancing weight, and if the distance data is equal to the theoretical distance, stopping moving the balancing weight. The invention further provides a replaceable structure for updating the tower crane. The effective length of the cargo boom can be automatically adjusted, moment balance of the two sides of the tower body is kept, and the advantages of being easy to operate, high in adaptability, high in working efficiency and the like are achieved.
本发明适用于工程机械领域,提供了一种用于塔吊更新的替换方法,包括以下步骤:S1.将起重臂沿水平方向伸缩至指定位置,计算起吊物体到塔身中心处的力矩M1;S2.基于力矩M1计算达到力矩平衡时配重块与塔身中心处的理论距离;S3.判断理论距离、配重块与塔身中心处的距离数据的大小关系,若理论距离大于或小于距离数据,进入步骤S4;S4.设定配重块的移动方向;S5.移动配重块,若距离数据等于理论距离,停止移动配重块。还提供一种用于塔吊更新的替换式结构。本发明可自动调整起重臂的有效长度,并保持塔身两侧的力矩平衡,具有操作简单、适应性强、工作效率高等优点。
