把需要移入的台车提前移送到台车移入导轨 2上, 需移入台车被移出后 主传动轮 6上形成了两个空齿槽, 当主传动轮 6上的这两个空齿槽转动一定 位置时, 快速移入机构 10的油缸 10】推动推进小车】04移动, 推进小车 104 通过两圆柱 105推动需移入的台车移动,当需移入的台车车轮 302与轨 12011 的外侧接触时, 在台车车轮 302压力的作 下, 轨 12011 向下旋转, 致使上 部可动外曲轨 201发生折叠变形, 当轨 12011 向下旋转到外侧面与台车移入 轨 2上表面重合时, 可动外曲轨 201发生折叠变形达到了极限位置, 也称为 换车位置, 此时轨 12011把台车移入轨 2和内直轨 5连通, 要移入的台车的 车轮 302可进入到内直轨 5上, 当要移入的台车到达一定位置, 要移入的台 车的滚套 301在主传动轮的轮齿的拨动下, 台车向前继续移动, 在要移入的 台车的车轮 302脱离轨 12011外侧面后, 在重锤 2013的作用下, 可动外曲轨 201发生展开变形并回复到初始位置。
实施例 2, 图 13所示。
本实施例是在实施例 1的基础上进行的变化, 不同点在于:
1。将实施例 1中的上部可动外曲轨 201简化, 取消轨 112012, 变成单一 的轨并加长轨 12011, 重锤 2013直接安装在轨 I20U上。
2.在可动外曲轨 201右下角处设有与内曲轨 3外形相吻合的圆弧台阶。 其余, 与实例 1相同, 可参见本说明书和实施例 1的有关说明。
另外, 需要注意的是: 上述实施例是本发明的个案, 它的作用之一是对 本发明起解释的作用, 而不应理解为对本发明做出的任何限制。
