上卧式闸门由于有独特的优点,在许多地方得到了应用。这种闸门升降时门体发生转动,都采用卷扬式启闭机,从而带来如下缺点:一是卷扬式启闭机价格贵,二是钢丝绳浸在水中容易锈蚀,三是启闭机体积和重量大,增加了工作桥和支墩的造价。为克服上述缺点,笔者在去年春天设计滨海县淤黄河节制闸时,选用了2×10T双吊点螺杆式启闭机,来启闭向上游翻的上卧式闸门。为在闸门升降翻转的过程中吊点中心轨迹必须为一铅直线,设计中采用闸门槽下游侧的曲线轨道来相适应。具体设
On the horizontal gate due to the unique advantages, has been applied in many places. This gate movements occur when the gate body are used winch hoist, which brings the following disadvantages: First, winch hoist expensive, the second is immersed in the rope easy to rust, the third hoist Large size and weight, an increase of working bridge and pier cost. In order to overcome the above shortcomings, the author designed 2 × 10T double-point screw hoist to design and implement the Yellow River dam of Binhai County in the spring of last year. To lift the gate in the process of lifting the hanging point center track must be a plumb line, the design of the sluice gate groove on the downstream side of the curve to adapt. Specific design
