全平衡垂直升船机提升系统研究

主提升系统是全平衡垂直升船机的关键设备,以水口全平衡垂直升船机为例,提出了承船厢运行速度曲线、控制承船厢与挡水门精确停位方法、事故紧急保护原理和关键参数计算方法。通过不同速度的试验,验证速度曲线的实用性。从运动学的角度分析了事故紧急保护的原理、确定关键参数的计算公式和方法。选择多组承船厢水深数据计算制动延迟时间和滑移行程,与现场试验数据基本相同,从理论和实践上验证了其原理的正确性。

Lifting system of full balancing vertical ship lift

The main lifting system is the key equipment in full balancing vertical ship lift.Taking shuikou fully balancing vertical ship lift as an example,we put forward the running speed curve of ship reception chamber,precise stop control method of ship reception chamber and lock heads backwater gate,and accident emergency protection principle and key parameters calculation method.The practicality of the speed curve is verified by the experiment of different speed.From the view of kinematics,the principle of accident emergency protection is analyzed,and calculation formula and method of key parameters are determined.We calculated brake delay time and slide stroke by multiple sets of ship reception chamber water depth datas,which were basically the same with field test data.The correctness of the principle is verified by theory and practice.
