Hydraulic rotary pile hammer
The invention discloses a hydraulic rotary pile hammer. The nitrogen chamber (3), the cylinder body (4) and the upper box body (5) are fixedly connected through the long bolt (2), the piston (8) reciprocates in the cylinder body (4) to hit the connector (14), and then the pile (15) is driven into the ground; when the piston (8) strikes the connector (14), the hydraulic motor (10) drives the transmission sleeve (13) to rotate through the chain wheel (11) and the chain (12), and then the pile (15) is driven to rotate. Therefore, the pile (15) is made to perform a rotational motion and a feed motion at the same time. And the friction force of the explored geology to the pile (15) is effectively reduced. In addition, if a cutting tool is installed at the front end of the pile (15), rock strata or stones can be drilled and cut.
本发明公开了一种液压旋转打桩锤。长螺栓（2）将氮气室（3）、缸体（4）及上箱体（5）紧固连接，活塞（8）在缸体（4）内往复运动，打击连接头（14），进而将桩（15）打入地下；活塞（8）在打击连接头（14）的同时，液压马达（10）通过链轮（11）、链条（12）驱动传动套（13）转动，进而带动桩（15）转动。使得桩（15）一边做旋转运动，一边做进给运动。有效的降低了被勘探地质对桩（15）的摩擦力。另外，如果在桩（15）前端安装切割刀具，还可对岩层或石块进行钻削切割。
