斗式提升机一般都采用重力式张紧机构。这种机构具有保持张紧力始终不变的优点,但在日常生产中却经常发生滑板卡死、张紧机构失去应有的作用、张紧力消失的现象。针对这一问题,我们对斗式提升机的张紧装置进行了改造。原机构如图1所示是一个杠杆机构,当配重杆上下运动时,轴承座 Bucket elevator are generally used gravity tensioning mechanism. This mechanism has the advantage of keeping the tension constant, but in daily production, skateboarding often occurs, tensioning mechanism loses its due role, tension disappears phenomenon. In response to this issue, we modified the bucket elevator tensioning device. The original mechanism shown in Figure 1 is a lever mechanism, when the weight bar up and down movement, the bearing seat
