Description

矩形灌注桩成孔机
一、技术领域
本发明涉及一种成孔机，特别是一种混凝土灌注桩用的矩形灌注桩成孔机。
二、背景技术：
目前，混凝土灌注桩所使用的成孔设备大都是成一圆孔的钻机，有些工程需要建造截面为矩形的混凝土灌注桩，圆孔的钻机就无能为力了。
三、发明内容：
本发明弥补了以上空白，提供了一种矩形灌注桩成孔机。
本发明是通过如下技术方案实现的：
一种矩形灌注桩成孔机，钻杆设于成孔机上部位置，钻杆下端连于框架上端，框架下端通过销轴销接于半月板A和半月板B的中间，液压油缸设于框架内，液压油缸上端销接于框架上端，液压油缸下端销接于连杆A和连杆B的上端，连杆A的下端销接于铰座A，铰座A设于半月板A的左端，连杆B的下端销接于铰座B，铰座B设于半月板B的右端，半月板A、半月板B侧面为半月形，截面为F形，半月板A、半月板B下部均设有数个刀齿。
本发明具有以下的特点：
本发明可成矩形孔。
四、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A—A视图。
图中：1、钻杆，2、框架，3、液压油缸，4、连杆A，5、连杆B，6、铰座A，7、铰座B，8、半月板A，9、半月板B，10、刀齿，11、销轴。
五、具体实施方式：
附图为本发明的一种具体实施例，该实施例钻杆1设于成孔机上部位置，钻杆下端连于框架2上端，框架下端通过销轴11销接于半月板A8和半月板B9的中间，液压油缸3设于框架内，液压油缸上端销接于框架上端，液压油缸下端销接于连杆A4和连杆B5的上端，连杆A的下端销接于铰座A6，铰座A6设于半月板A的左端，连杆B的下端销接于铰座B7，铰座B7设于半月板B的右端，半月板A、半月板B侧面为半月形，截面为F形，半月板A、半月板B下部均设有数个刀齿10。
本发明工作时，液压油缸总是一伸一缩运动，液压油缸运动过程中通过连杆A、连杆B驱动半月板A、半月板B运动，半月板A、半月板B上的刀齿在运动中挖切土层成孔，成孔泥渣由反循环系统置换（反循环系统在图中未标出）。
