株洲二线船闸闸门及启闭机优化设计

株洲二线船闸人字门为超大型闸门,控制闸门的变形量是设计的重点和难点,船闸启闭机集中布置在闸首上部,需充分考虑吊装及检修方便。闸门门体结构进行多方案布置,分别进行结构计算,研究结构本身抵抗变形的能力,对闸门的附件进行优化设计。启闭机布置采用两种方案,并进行优缺点比选,重点考虑吊装、检修、通行、美观等因素。结果表明,闸门采用多主横梁+八隔板+水平次梁的方案刚度最好,防护系统及人行桥优化设计后更趋合理,启闭机布置采用空箱+吊物孔电动盖板方案,实现了吊装检修和通行方便。

Optimal design of gate and hoist for Zhuzhou second ship lock

The mitre gate of Zhuzhou second ship lock is a super-large gate.The deformation control of the gate is a key and difficult point in the design.The lock hoist is centrally arranged on the upper part of the lock head,and the convenience of hoisting and maintenance should be fully considered.The structure of the gate is arranged by various schemes,and the structural calculations are carried out separately.The ability of the structure itself to resist deformation is emphatically studied,and the accessory of the gate is optimized.The hoist is arranged by two schemes,and the advantages and disadvantages are compared,the factors such as lifting,overhaul,passage and beauty are mainly considered.The results show that the stiffness of the main beam+eight partitions+horizontal secondary beam of the gate is the best,and the protection system and the pedestrian bridge are more reasonable after optimizing design.The hoist is arranged with the scheme of empty box structure+lifting hole electric cover plate,which achieves convenient lifting,overhaul and access.
