本专利属于地质勘探中小口径深井钻进范围。铁砧9位于壳体的上部1,铁砧里面设有推杆10。碎岩工具的转动机构是带有回动弹簧15的轴11。它用带有滚动体的螺旋接头13与壳体下部2连接。而与壳体上部是通过棘轮啮合的离合器20连接,与推杆是通过液动加力器16相连接。此加力器上有上活塞17和下活塞18。当液动冲击器工作时,位于壳体上部的冲击锤6受到推杆10端部的冲击,并把这种冲击向下传送。由于相互撞击,冲锤6的一部分冲力传给铁
This patent belongs to the geological exploration of small-bore deep well drilling range. The anvil 9 is located on the upper part 1 of the housing, and the push rod 10 is disposed inside the anvil. The rocking tool turning mechanism is a shaft 11 with a return spring 15. It is connected to the lower part 2 of the housing by means of a screw connection 13 with a rolling body. And the upper part of the housing is connected with the clutch 20 which is engaged with the ratchet wheel, and the push rod is connected with the hydraulic booster 16. This booster has an upper piston 17 and a lower piston 18. When the hydraulic impactor is in operation, the impact hammer 6 located in the upper part of the housing is impacted by the end of the push rod 10, and the impact is transmitted downward. Due to the collision with each other, a part of the impact of the hammer 6 is transmitted to the iron
