根据三峡升船机船厢、上下闸首等设备设施的实际布置和结构特点,针对不同类型的典型船型,研究牵引距离、牵引角度、牵引力等技术指标,提出轨道小车和电动推轮牵引两种三峡升船机船舶进出船厢牵引方案,论证方案的可行性,并结合升船机现阶段通航运行时间和牵引预期耗时对方案进行比选,得出预期全年日均通航时间由 47 min 59 s 缩短至43 min 47 s,较现行船舶通航效率有所提升,为后续的船舶牵引工程实现提供理论支撑.
According to the actual layout and structural characteristics of the equipment and facilities such as the ship chamber and the upper and lower lock heads of the Three Gorges ship lift,the technical indexes such as traction distance,traction angle and traction force are studied for different types of typical ship types.Two traction schemes for ships entering and leaving the ship chamber of the Three Gorges ship lift are put forward,which are rail trolley and electric wheel traction.The feasibility of the scheme is demonstrated,and compared with the current navigation operation time of the ship lift and the expected traction time.It is concluded that the expected average daily navigation time of the whole year is shortened from 47 min 59 s to 43 min 47 s,which is improved navigation efficiency compared with the current ship,and provides theoretical support for the subsequent ship traction projects.
