Description

拱形隧道挖掘机
技术领域
本发明涉及一种隧道挖掘机，特别是一种隧道施工机械的拱形隧道挖掘机。
背景技术
目前，隧道挖掘机都是通过驱动一个刀盘旋转切削来完成的，刀盘旋转切削时只能形成一个圆形隧道。
发明内容
本发明弥补了以上隧道挖掘机的缺点，提供了一种拱形隧道挖掘机。
本发明是通过如下技术方案实现的：
一种拱形隧道挖掘机，电机左端设有主动齿轮，主动齿轮啮合从动齿轮，主动齿轮左端连有一轴，从动齿轮左端连有二轴，一轴左端连有一拐轴，二轴左端连有二拐轴，一拐轴通过一杆销连一臂右端，二拐轴通过二杆销连二臂右端，一臂的左端销连拱形体上部，一臂的中间销连挡土板，二臂的左端销连矩形体下部，二臂中间销连挡土板；一臂为并列的两根，左端通过两个一销座销连拱形体，右端连接为一体，二臂的形状与一臂的形状等同。
本发明具有以下的特点：
本发明可挖掘拱形隧道。
附图说明
下面结合附图对本发明作进一步的说明：
图1为本发明的结构示意图；
图2为图1的A—A向视图；
图3为图1的B—B剖视图；
图中：1、支撑，2、电机，3、主动齿轮，4、从动齿轮，5、轴承座，6、一轴，7、二轴，8、一拐轴，9、二拐轴，10、一杆，11、二杆，12、三杆，13、四杆，14、一臂，15、二臂，16、三臂，17、四臂，18、挡土板，19、一销座，20、二销座，21、三销座，22、四销座，23、拱形体，24、矩形体，25、刀头。      
具体实施方式
附图为本发明的一种具体实施例，该实施例电机2左端设有主动齿轮3，主动齿轮啮合从动齿轮4，主动齿轮左端连有一轴6，从动齿轮左端连有二轴7，一轴左端连有一拐轴8，二轴左端连有二拐轴9，一拐轴通过一杆10销连一臂14右端，二拐轴通过二杆11销连二臂15右端，一臂的左端销连拱形体23上部，一臂的中间销连挡土板18，二臂的左端销连矩形体24下部，二臂中间销连挡土；一臂为并列的两根，左端通过两个一销座销连拱形体，右端连接为一体，二臂的形状与一臂的形状等同。
四杆13下端销连二臂，四杆上端销连四臂17右端，四臂左端销连矩形体上部，四臂中间销连挡土板；三杆12上端销连二臂，三杆下端销连三臂右端，三臂左端销连拱形体下部，三臂中间销连挡土板。
一轴通过两个轴承座固定于上边支撑，二轴通过下边两个轴承座固定于下边支撑。
主动轮和从动轮是大小和形状都一样的两个齿轮；拱形体的横截面形状为拱形，矩形体的横截面形状为矩形。
本发明工作时，电机驱动主动轮同时带动从动轮旋转，由此通过一轴驱动一拐轴正转，通过二轴驱动二拐轴反转，两拐轴在转动过程中分别推拉一臂和二臂的右端，拱形体和矩形体便相对运动，拱形体和矩形体上的刀头便挖掘成拱形隧道。
