起重船在犍为船闸检修中的应用

Application of crane ship in Qianwei ship lock maintenance

针对山区河流大型船闸检修问题,从投资性价比、共用性、便捷性等方面对检修闸门形式和起吊设备进行比较,从而确定犍为船闸“浮式叠梁检修门+起重船”的检修方案。详细描述犍为船闸检修的特殊性,并开展起重船在犍为船闸检修中的吊装工艺流程研究。通过经验总结、边界条件模拟等方法得出起重船在吊装超大型浮式叠梁检修门中的关键控制要素。详细介绍了起重船在山区河流大型船闸中起吊检修闸门的应用,为类似大型船闸检修提供了经验和借鉴。

Aiming at the maintenance of large ship locks in mountainous rivers,the maintenance gates types and lifting equipment are compared from the aspects of investment cost-effectiveness,commonality,convenience,etc.,therefore,it is determined that the maintenance plan of Qianwei ship lock is“floating stacked beam maintenance door+crane ship”.The particularity of Qianwei ship lock maintenance is described in detail,and the research on the hoisting process of the crane ship in Qianwei ship lock maintenance is carried out.Through experience summary and boundary condition simulation methods,the key control elements of crane ship in hoisting super large floating stacked beam maintenance door are obtained.The article introduces in detail the application of crane ships in the lifting and maintenance of gates in large ship locks in mountainous rivers,which provides experience and reference for similar large ship locks.
