【摘要】:正 1999年,沐浴水库管理局在水库岸边的自有果园,兴建了灌溉系统,该系统的扬水站选用了缆车式移动提水装置的型式。根据地形情况,扬水站的坡道由不同坡比的4个坡段组成,弯坡有凹角也有凸角。已有的泵车模式缺乏在这种坡道上移动和工作的适应能力。另外传统的保险装置存在构造复杂,操作不便和响应迟钝的特点,而且这些问题在库区移动式扬水站建设中带有普遍

拉动刹车块靠在刹车轮上,当刹车块尖角进人刹车轮凹槽时,刹车块就将刹车轮止住,因刹车轮与车轮、车轴通过键固定在一起,只能滑动,因滑动摩擦力远远大于滚动摩擦力,泵车便不会因失去钢丝绳牵引而快速下滑,从而能使泵车平衡地靠上预先固定轨道的夹板上,防止了泵车冲入水中或倾
