The invention provides a hard rock cutterhead and a cantilever roadheader including the cutterhead, the hard rock cutterhead includes a tapered main structure of the cutterhead, the main structure of the cutterhead includes a head, spokes and flanges, the head is connected with spokes, the spokes are connected with flanges, the head and spokes are provided with detachable cutters, the cantilever roadheader includes the hard rock cutterhead. Advantages of the invention: the cutter head structure is more evenly stressed, has strong resistance to deformation and damage, and can withstand high thrust, high speed and other driving conditions; the cutter head is made of whole plate processing or steel plate welding, with better overall strength and rigidity; the cutter head is in the form of end cover located on the mounting surface of the cutter head, which can improve the rock breaking efficiency; the cutter head center hob can advance when the cutter head swings for cutting It can be retracted to effectively avoid the abnormal damage of the center hob, such as eccentric wear and edge collapse; the interchanged installation of hob and toothed cutter can not only excavate soft soil, but also expand the excavation of hard rock; the cutter head can swing up and down left and right to excavate circular and irregular sections.
【技术实现步骤摘要】
一种硬岩刀盘和包括该刀盘的悬臂掘进机
本专利技术涉及隧道掘进刀盘,特别是指一种硬岩刀盘和包括该刀盘的悬臂掘进机。
技术介绍
随着掘进技术的向前发展,在硬岩地层的施工,不仅要求安全可靠,同时对掘进效率的要求也在不断提高,而在硬岩地层中使用TBM设备则成本过高,若使用钻爆破岩则安全性较低,若使用连续采煤机或掘锚联合机组则掘进效率较低,而作为一种安全有保障、成本较低、掘进效率较高的悬臂掘进机将得到大力发展。而目前悬臂掘进机的掘进头主要是两个左右对称的半球形或滚筒形的截割头(如名称为“一种横轴式掘进机截割模拟实验台”,申请号为201811105636.7的专利技术专利申请),或者是单个圆锥形或圆锥圆柱形的截割头(如名称为“复合式悬臂掘进机”,申请号为201210207419.5的专利技术专利申请),截割头上齿刀是按照一定间距沿螺旋线布置的,在硬岩地层和使用TBM刀盘相比,掘进效率较低。因此对一种能高效掘进的悬臂掘进机掘进机头的追求不断提升。
