摘要
大型船闸人字闸门通常设置浮箱以改善顶底枢运转件的受力状态,降低门头下垂量。在同等浮力下,先对比矩形、U型、⊥型、L型、J型、T型、Π型等7种不同形式的浮箱,分析顶底枢支反力、门头下垂量、固有频率、通气路径等特性,给出相对合理的浮箱结构形式;在此基础上,再对比1层、1层半、2层、3层、4层等5种不同浮力大小的浮箱,分析并给出相对合理的浮箱浮力控制范围。
At the miter gate of large-scale ship lock, buoyancy tank is usually set to improve the stress stateof operating parts of the top and bottom pivotkinds of different buoyancy tanks of the rectan, angle,d to reduce the drooping volume of gate head. First of all, sevenU type, type, L type, J type, T type and Ⅱtype were comparedunder the same buoyancy to analyze the features of bearing reaction of top and bottom pivot, drooping volume of gatehead, natural frequency and ventilation path, and give a relative reasonable structural form of buoyancy tank.On thisbasis, five kinds of buoyancy tanks of one layer, one and a half layer, two layers, three layers, and four layers withdifferent buoyancy forces were compared to analyze and give aforce of buoyancy tankrelatively reasonable control range for the buoyancy
