Description

半圆隧道挖掘机
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半圆隧道挖掘机。
背景技术
半圆隧道由于其巨大的交通能力而逐渐被人们接受，但是，全断面掘进的半圆隧道挖掘机的制造技术非常复杂。
发明内容
本发明弥补了以上缺点，提供了一种简单的能全断面掘进的半圆隧道挖掘机。
本发明是通过如下技术方案实现的：
一种半圆隧道挖掘机，减速机固定在底架上，减速机向左输出中轴，中轴的左端固定主动轮，主动轮上偏心固定一只边轴，边轴上套有矩形体，矩形体固定在扇形刀盘上，扇形刀盘是由多个辐条成放射状组成的形状为扇形的刀盘，扇形刀盘的底端中心铰接于底轴，底轴的右端固定于底架的左端，扇形刀盘上设有多把滚刀。
本发明具有以下的特点：
本发明扇形刀盘在绕底轴左右摆动的过程中，多把滚刀将隧道的断面切削成半圆断面。
附图说明
下面结合附图对本发明作进一步的说明：
图1为本发明结构示意图；
图2为图1的A—A视图；
图3为图1的B—B视图；
图中：1、底架，2、减速机，3、中轴，4、主动轮，5、边轴，6、矩形体，7、底轴，8、扇形刀盘，9、滚刀。
具体实施方式
附图为本发明的一种具体实施例，该实施例减速机2固定在底架1上，减速机向左输出中轴3，中轴的左端固定主动轮4，主动轮上偏心固定一只边轴5，边轴上套有矩形体6，矩形体固定在扇形刀盘8上，扇形刀盘是由多个辐条成放射状组成的形状为扇形的刀盘，扇形刀盘的底端中心铰接于底轴7，底轴的右端固定于底架的左端，扇形刀盘上设有多把滚刀9。
本发明工作时，减速机通过中轴驱动主动轮左转半圈、然后右转半圈如此往复，由此通过矩形体驱动扇形刀盘绕底轴左右摆动，扇形刀盘左右摆动的幅度正好是一个半圆，因此，多把滚刀将隧道的断面切削成半圆断面。
