Abstract

本发明涉及一种钻井工程中使用的无扭力钻机,钻杆下部固定有十字架,十字架下部固定有销轴,四个液压油缸A、B、C、D的一端分别铰接于十字架的四只腿上,四个液压油缸的另一端分别铰接于四个刀杆A、B、C、D,四个刀杆的内侧端通过四个铰套A、B、C、D销接于销轴,四个刀杆上均设有数个刀齿,无扭力钻机四个刀杆以销轴为圆心两两相向摆动,对外作用力相互抵消,因此钻头不产生扭力,可省去钻杆或钻杆做的很细小。

Description

无扭力钻机
一、技术领域
本发明涉及一种钻机,特别是一种钻井工程中使用的无扭力钻机。
二、背景技术:
目前,钻井工程中所使用的钻机钻头旋转时产生巨大的扭力,此扭力都是靠钻杆传递的,因此,普通钻机所使用的钻杆都做的很粗大,这给施工带来很大的不便。
三、发明内容:
本发明提供了一种无扭力钻机。
本发明是通过如下技术方案实现的:
一种无扭力钻机,钻杆下部固定有十字架,十字架下部固定有销轴,四个液压油缸A、B、C、D的一端分别铰接于十字架的四只腿上,四个液压油缸的另一端分别铰接于四个刀杆A、B、C、D,四个刀杆的内侧端通过四个铰套A、B、C、D销接于销轴,四个刀杆上均设有数个刀齿。
本发明具有以下有益效果:
无扭力钻机四个刀杆以销轴为圆心两两相向摆动,对外作用力相互抵消,因此钻头不产生扭力,可省去钻杆或钻杆做的很细小。
四、附图说明:
下面结合附图对本发明作进一步的说明:
附图1为本发明的结构示意图;
附图2为四刀杆及液压油缸结构视图。
图中:1、钻杆,2、液压油缸A,3、液压油缸B,4、刀杆A,5、刀杆B,6、铰套A,7、铰套B,8、十字架,9、销轴,10、刀齿,11、刀杆C,12、刀杆D,13、液压油缸C,14、液压油缸D。
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下部固定有十字架8,十字架下部固定有销轴9,四个液压油缸A、B、C、D的一端分别铰接于十字架的四只腿上,四个液压油缸的另一端分别铰接于四个刀杆A、B、C、D,四个刀杆的内侧端通过四个铰套A、B、C、D销接于销轴9,四个刀杆的长度相等对地面的角度亦相等,四个刀杆上均设有相同个数大小亦相同的刀齿10。
本发明工作时,液压油缸A、液压油缸B外伸的同时液压油缸C、液压油缸D同步回缩,液压油缸A、液压油缸B回缩的同时液压油缸C、液压油缸D同步外伸,由此驱动四个刀杆以销轴9为圆心两两相向摆动,刀杆在摆动过程中刀杆上的刀齿将地层土切割搅拌造浆,浆液通过反循环系统置换。
