Multidirectional variable-grade differential stirring drilling machine and construction method thereof
The invention discloses a multidirectional grade-changing differential stirring drilling machine and a construction method thereof, and belongs to the field of foundation treatment equipment. The multidirectional grade-changing differential stirring drilling machine comprises a pile frame, a power system, a drill rod, a transmission system, a drill bit and a fluid director; the power system is installed on a mast of the pile frame or a chassis of the pile frame, the drill rod comprises an inner drill rod and an outer drill rod, the lower end of the drill rod is connected with the drill bit, the upper end of the drill rod is connected with the fluid director, and the transmission system is installed on the mast of the pile frame, is in sliding connection with the mast and enables the inner drill rod and the outer drill rod to be in transmission connection through a gear. The power system drives the outer drill rod to rotate, and the outer drill rod drives the inner drill rod to rotate in the opposite direction through the transmission system. By adopting the middle or lower power system, the equipment center is lowered, and the operation safety of the equipment is improved; by arranging the transmission system, transmission between the outer drill rod and the inner drill rod is achieved, and a traditional top drive motor is replaced.
本发明公开了一种多向变级差速搅拌钻机及其施工方法，属于地基处理设备领域，包括桩架、动力系统、钻杆、传动系统、钻头、导流器；动力系统安装在桩架的桅杆上或桩架的底盘上，钻杆包括内钻杆、外钻杆，钻杆下端与钻头连接，钻杆上端与导流器连接，传动系统安装在桩架的桅杆上，且与桅杆之间滑动连接，传动系统将内钻杆与外钻杆通过齿轮传动连接，动力系统带动外钻杆转动，外钻杆通过传动系统带动内钻杆朝相反方向转动。本发明通过采用中置或者下置动力系统，降低设备中心，增大了设备的运行安全性；通过设置传动系统实现了外钻杆与内钻杆之间的传动，替换了传统的顶驱电机。
