水电站弧门吊装的传统方法水电站弧形闸门是指挡水面为圆柱体的部分弧形面的闸门,由转动门体、埋设构件及启闭设备3部分组成。其支臂的支承铰位于圆心,启闭时闸门绕支承铰转动,启闭力较小,水力学条件好,广泛用于各种类型的水道上作为工作闸门运行。水电站弧形闸门安装时,一般采用履带起重机或缆索式起重机吊装闸门构件,采用此2种吊装方法,具有以下缺点:履带起重机对施
The traditional method of hoisting of hydropower station arc gate The hydropower station arc gate refers to the part of the arc surface of the cylinder whose water blocking surface is a gate. It is composed of the rotating door body, the embedded components and the opening and closing equipment. The supporting hinge of the supporting arm is located at the center of the circle. When the door is opened and closed, the gate rotates around the supporting hinge, the opening and closing force is small, and the hydraulic conditions are good. The utility model is widely used as a working gate for various types of watercourses. When the radial gate of a hydropower station is installed, crawler cranes or cable-type cranes are generally used to lift the gate components. With these two lifting methods, the following shortcomings are achieved:
