摘要:

为解决我国煤矿巷道领域类矩形隧道全断面一次掘进成型及快速掘进难题,针对宽6 m、高4.2 m的类矩形隧道,开展全断面掘进机切割机构研究。通过分析多种隧道成型技术方案特点,确定了一种由左右三臂刀盘和上下截割滚筒组成的切割机构技术方案;结合煤矿巷道实际需求,设计了类矩形隧道成型形状;开发设计了刀盘、截割滚筒结构,进行了截齿选用、布置;采用SolidWorks软件分别建立了三臂刀盘和截割滚筒三维模型,利用ANSYS软件分别对三臂刀盘和截割滚筒做了模态分析和静力学分析。结果表明: 1)采用圆形刀盘与截割滚筒组合式切割机构,能够实现全断面类矩形隧道的掘进成型; 2)切割机构能够满足强度及刚度的要求且不会发生共振现象; 3)实际煤矿巷道掘进应用表明,切割机构具有较高的掘进效率,在煤矿巷道类矩形隧道领域具有较好的应用前景。

Abstract: To realize onetime tunneling and forming as well as rapid excavation of a quasirectangular fullface tunnel in the field of coal mine roadway in China, the cutting mechanism of the tunnel boring machine is investigated for a quasirectangular tunnel with a width and height of 6 m and 4.2 m, respectively. First, the characteristics of multiple tunnelforming technical schemes are analyzed to select a cutting mechanism. The selected mechanism is realized by arranging triplearm cutterheads on the right and left and cutting drums on the top and bottom of the machine. Second, the forming shape of the tunnel is designed according to the actual demands of coal mine tunnels. Third, the structures of the cutterhead and cutting drum are designed, and the cutting picks are selected and arranged. Finally, threedimensional models of the triplearm cutterheads and cutting drums are constructed using SolidWorks, and modal and static analyses are then performed using ANSYS. The following results are obtained. (1) The proposed cutting mechanism can realize onetime tunneling and the formation of a quasirectangular fullface tunnel. (2) This cutting mechanism meets the strength and stiffness requirements of the tunnel without the occurrence of resonance phenomenon. The application results demonstrate that the recommended cutting mechanism has high tunneling efficiency and good application prospects for constructing a quasirectangular tunnel for coal mine roadway.
