Description
本发明涉及巷道掘进设备技术领域，更具体涉及一种大倾角小转弯半径圆形全断面模块化掘进机。
全断面掘进机(TBM)是一种集机械、液压、电子、激光导向、传感技术于一体的地下工程装备，它可以实现高效破岩，连续出渣、快速支护、通风除尘、供排水多道工序同步作业，具有安全、高效、环保、综合效益高等优点。TBM***组成通常包括刀盘掘进***，输送***，支护***，勘探***及相应配套***，在TBM掘进过程中，刀盘掘进***负责巷道掌子面岩体破碎，输送***负责将破碎的岩石运输出去，支护***负责对成型的围岩进行及时支护，勘探***负责定期对前方地质情况进行勘探。
目前TBM多用于隧道建设，其隧道成型多为直线型或大半径曲线型，因此传统的隧道TBM无需突破小半径转弯及大倾角掘进技术，而煤巷掘进为了后续煤矿开采，因此煤巷成型特点不同于隧道，其成型多为小半径曲线型，因此将TBM用于煤巷开挖则需克服小半径转弯及大倾角掘进技术难题，而要解决该技术难题，则需要解决两方面技术难点：TBM小半径转弯掘进问题，TBM小半径转弯岩渣连续输送问题。
有鉴于此，有必要对现有技术中的掘进机予以改进，以解决上述问题。
