三峡工程齿轮齿条爬升式升船机设计

The design of gear rack climbing type ship lift of Three Gorges Project

三峡升船机具有提升重量大、升程高、上下游通航水位变幅大、水位变率快等特点,是目前世界上规模和技术难度最大的升船机。经过方案比选,三峡升船机最终确定采用齿轮齿条爬升式,其设备构造复杂,制造、安装及土建结构施工精度要求很高,并首次采用中德联合设计方式。概要介绍了三峡工程齿轮齿条爬升式升船机的总体布置、以及塔柱结构、重要设备的设计方案与关键技术。

The Three Gorges ship-lift is the largest and the most difficult one in the world with the charac-teristics of large lifting weight, high lift range, big fluctuation of water stage between upper and lower reaches and quick variation of navigable water level. After scheme comparison, the gear-rack climbing type ship-lift is selected, which is characterized by complicated structure of facilities and high precision requirements of manufacture, installation and construction. Meanwhile the Sino-German co-design method is first adopted. The general layout of gear-rack climbing type ship-lift, as well as the design schemes and key techniques of tower structure and important equipment are briefly introduced.
