摘要
针对绞吸挖泥船在清淤过程中挖深不足的问题和环保施工的要求,对绞吸挖泥船进行适应性改造,具体为将绞吸挖泥船前端绞刀挖掘设备更换为环保清淤设备,实现了绞吸挖泥船的环保清淤功能。为了增加清淤设备的灵活操作性能,开发了一种新型清淤设备,位于桥架和清淤吸头之间。针对水平悬挂、36 m挖深和40 m挖深3种工况,对清淤设备关键部件进行强度分析。结果表明,关键部件最大应力为84.2 MPa、最大变形为2.5 mm,满足强度和刚度要求,优化后关键部件符合施工要求。
In view of the problem of insufficient dredging depth of cutter suction dredger and the requirements of environmental protection construction,the cutter suction dredger is adapted to be reformed,specifically replacing the cutter excavating equipment at the front end of cutter suction dredger with environmental protection dredging equipment,which realizes the environmental protection dredging function of cutter suction dredger.In order to increase the flexibility of the dredging equipment operation performance,a new type of dredging equipment is developed which is located between the bridge and desilting suction head.According to the three working conditions of horizontal suspension,36 m excavation depth and 40 m excavation depth,the strength of key components of dredging equipment is analyzed.The results show that the maximum stress of the key components is 84.2 MPa and the maximum deformation is 2.5 mm,which meets the requirements of strength and rigidity,and the optimized key components meet the construction requirements.
