1.问题的提出作为“六五”计划重点工程的白山电站,水坝采用了弧形的坝体,要求我所为其设计跨度与轮距均为10米,起重量为2×125吨,能沿弧线运行的门式启闭机。启闭机的运行轨道曲率半径如图1所示。我所根据松花江上游水流量小,含沙量少,而库容量较大的特点,认为泄水闸门及冲沙闸门是很少使用的,启闭机年利用率很低,而弧形轨道的曲率半径又较大,因此采用了常
1. Proposal of the Question Baishan Hydropower Station, a key project of the “Sixth Five-Year Plan”, uses curved dams. The design requires that the span and track length of the dam are both 10 meters and the lifting capacity is 2 × 125 tons. The gantry operates along an arc. Hoist running track radius of curvature shown in Figure 1. According to the characteristics of small water flow and less sediment in the upper reaches of the Songhua River and larger storage capacity, I think sewer gates and flushing gates are seldom used, and the annual utilization rate of hoist is very low. However, the arc track The larger the radius of curvature, so often used
