Description

双螺旋成槽机
技术领域
本发明涉及一种成槽机,特别是一种地下连续墙成槽用的双螺旋成槽机。
背景技术
目前,建造地下连续墙的成槽机普遍存在结构复杂、造价高等特点。
发明内容
本发明弥补了以上缺点,提供了一种双螺旋成槽机。
本发明是通过如下技术方案实现的:
一种双螺旋成槽机,电机上端连有钻杆,电机下端连有变速箱,变速箱左边设有左旋螺杆,左旋螺杆上设有两个螺旋外套,变速箱右边设有右旋螺杆,右旋螺杆上亦设有两个螺旋外套,四个螺旋外套下端均分别固定有拨叉;四个拨叉下部分别设有四个立杆,每个立杆上端固定有挡轴,下端固定于刀架,中间通过销铰接支撑杆,支撑杆通过连接体固定于变速箱下端,每个刀架下均设有数个刀头。
本发明具有以下有益效果:
本发明通过左右两个螺杆驱动四个刀架相向往复摆动切割地质土成槽,结构简单、可靠。
附图说明
下面结合附图对本发明作进一步的说明;
附图为本发明的结构示意图;
图中:1、钻杆,2、电机,3、变速箱,4、左旋螺杆,5、右旋螺杆,6、螺旋外套,7、拨叉,8、挡轴,9、立杆,10、销,11、刀架,12、刀头,13、连接体,14、支撑杆。
具体实施方式
附图为本发明的一种具体实施例,该实施例电机上端连有钻杆,电机下端连有变速箱3,变速箱左边设有左旋螺杆4,左旋螺杆上设有两个螺旋外套6,变速箱右边设有右旋螺杆5,右旋螺杆上亦设有两个螺旋外套6,四个螺旋外套下端均分别固定有拨叉7;四个拨叉下部分别设有四个立杆9,每个立杆上端固定有挡轴8,下端固定于刀架11,中间通过销10铰接支撑杆14,挡轴8设于拨叉的两个拨臂之间,支撑杆通过连接体固定于变速箱下端,每个刀架下均设有数个刀头12。
本发明工作时,电机通过变速箱驱动左旋螺杆、右旋螺杆同步顺时针方向旋转,使变速箱右边的两个螺旋外套和左边的两个螺旋外套同步向变速箱运动一定距离后,左右两螺杆再逆时针方向旋转,使螺旋外套再反方向运动,如此反复,螺旋外套上的拨叉拨动立杆上端的挡轴左右往复运动,驱动四个刀架相向往复摆动,刀架上的刀头切割地质土成槽,成槽泥浆由循环系统置换。
