悬臂式掘进机的改型设计

Modification Design of Boom-type Roadheader

在截割过程中,横轴式可以进行上下左右摇摆截割,方便灵活。可伸缩的截割臂,在解决掘进机掘进面窄的问题上发挥了很大作用,掘进机截割部可伸缩,加大了截割部的长度,从而加大了截割头经过的截割面,提高了掘进效率。

The belt expands and contracts cutting arm, played very major role in solution mechanical boring machine cutting department belt expand and contracted, has increased cutting department length, thus has enlarged cutting surface which a cutting institute passed through, enhanced tunneling efficiency.
