构皮滩钢丝绳卷扬下水式升船机受力特性观测分析

构皮滩第1、3级升船机是目前世界上建成的最大的钢丝绳卷扬下水式垂直升船机。通过原型观测分析升船机出入水运行受力特性，验证升船机各项创新设计。结果表明，船厢按设计速度出入水运行平稳收敛，溢流孔风速、附加水动力荷载、船厢应力与变形、卷筒扭矩与应力等参数均在预期和安全范围内稳定变化，船厢排气孔布置、底铺板楔形体等设计取得良好效果；在设计运行速度内，船厢出入水速度对升船机受力特性影响不大，出入水速度尚有一定优化空间。

Observation of mechanical characteristics of wire rope hoist ship lift with chamber entering water in Goupitan

Ship lifts of first step and third step in Goupitan are the largest wire rope hoist vertical ship lifts with chamber entering water built in the world at present. This paper investigates the mechanical characteristics in the processes of chamber getting in and out water by prototype observation, and verifies some innovation designs of the ship lift. The results indicate that the ship lift runs smoothly and stably when the chamber gets in and out of water with design speed. The parameters, such as wind speed of the overflow holes, hydraulic load on the chamber, chamber stress and deformation, rolling drum torque and stress, stably change within the expected and safety range. Good results are achieved in the design of the blow holes and the wedge shape of bottom plate of the chamber. Within the design operation speed, the getting in and out of water speeds of the chamber have little impact on the mechanical characteristics of the ship lift, and there is still some room to optimize the chamber running speed.
