According to the actual working conditions of bolting-shotcrete supporting in coal-mine tunnel,the working mechanism of different buckets was studied,their merits and demerits were analysed,and the double-crank grab bucket with assistant linkage was proved to be an ideal choice of grabbing materials in coal-mine tunnel because its motion trace was definite and symmetric and occupied lesser space.
从巷道锚喷支护中物料抓取的实际作业环境出发,对拟采用的几种抓斗的工作机理进行了分析研究,比较了各方案的优缺点,指出辅助连杆的双曲柄抓斗的运动轨迹确定、对称,且具有在竖直方向上占用空间最小的特点,是井下巷道施工中物料抓取的理想选择,这种设计方法能够为相关抓取装置的设计起到参考作用。
