Description

无扭矩钻机
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矩钻机。
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矩,此扭矩都是靠钻杆来平衡的,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。
发明内容
本发明弥补了以上缺点,提供了一种无扭矩钻机。
本发明是通过如下技术方案实现的:
一种无扭矩钻机,钻杆两侧分别连有左软管和右软管,左软管的左端连于左钢管的上端,右软管的右端连于右钢管的上端,左钢管下端以及右钢管下端均连于圆钢管;钻杆下端固定有底杆,底杆左端固定一轴销,轴销上设有能绕轴销转动的左齿轮,左齿轮上固定有左凸轮,底杆右端亦固定一轴销,轴销上设有能绕轴销转动的右齿轮,右齿轮上固定有右凸轮;主齿轮由电机驱动,主齿轮啮合于左齿轮,左齿轮亦啮合于右齿轮;左凸轮上端设有左横杆,左横杆固定于左钢管的右边,右凸轮上端设有右横杆,右横杆固定于右钢管的左边;左钢管下端固定于圆柱锤左端,右钢管下端固定于圆柱锤右端。
本发明具有以下有益效果:
无扭矩钻机通过圆柱锤在重力的作用下落下,同时,水嘴喷水,水夹杂着泥土由冒水孔冒出造孔,无扭矩产生,可以省掉钻杆或钻杆做的很小。
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剖视图。
图中:1、钻杆,2、接头,3、左软管,4、右软管,5、左套,6、右套,7、左杆,8、右杆,9、主齿轮,10、电机,11、配重块,12、左横杆,13、右横杆,14、左钢管,15、右钢管,16、左齿轮,17、右齿轮,18、左凸轮,19、右凸轮,20、底杆,21、圆柱锤,22、圆钢管,23、水嘴,24、冒水孔,25、挡圈,26、轴销。
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1两侧分别连有左软管3和右软管4,左软管的左端连于左钢管14的上端,右软管的右端连于右钢管15的上端,左钢管下端以及右钢管下端均连于圆钢管22;钻杆下端固定有底杆20,底杆左端固定一轴销26,轴销上设有能绕轴销转动的左齿轮16,左齿轮上固定有左凸轮18,底杆右端亦固定一轴销,轴销上设有能绕轴销转动的右齿轮17,右齿轮上固定有右凸轮19;主齿轮9由电机10驱动,主齿轮啮合于左齿轮16,左齿轮亦啮合于右齿轮;左凸轮上部设有左横杆12,左横杆固定于左钢管的右边,右凸轮上部设有右横杆13,右横杆固定于右钢管的左边;左钢管下端固定于圆柱锤左端,右钢管下端固定于圆柱锤右端。
左钢管上设有一只左套5,左套通过左杆7固定于钻杆,右钢管上设有一只右套6,右套通过右杆8固定于钻杆。
圆钢管为一圆形,设于圆柱锤内,圆钢管下部设有多个水嘴。
圆柱锤为一圆柱体,其上设有多个冒水孔。
本发明工作时,电机的主齿轮驱动左齿轮顺时针旋转,左齿轮驱动右齿轮逆时针旋转,由此驱动左凸轮绕左边的轴销顺时针旋转,右凸轮绕右边的轴销逆时针旋转,左凸轮在顺时针旋转过程中,向上推动左横杆带动圆柱锤的左端向上移动,同时,右凸轮在逆时针旋转过程中,向上推动右横杆带动圆柱锤的右端向上移动,当左凸轮和右凸轮转过一定角度时,左横杆脱离左凸轮,右横杆脱离右凸轮,圆柱锤在重力的作用下落下,同时,水嘴喷水,水夹杂着泥土由冒水孔冒出,流到孔外置换。
