一种深孔钻进装置
摘要：
本实用新型涉及一种深孔钻进装置，属于岩体钻孔技术领域，包括大直径钻头、钻杆连接件、减振装置、轻质小直径钻杆，大直径钻头置于顶端用于钻孔，大直径钻头和轻质小直径钻杆之间螺纹连接，钻杆连接件置于轻质小直径钻杆之间可以将其连成一个整体，在适当位置，减振装置替代部分钻杆连接件置于轻质小直径钻杆之间，减振装置直径略小于大直径钻头直径，可以有效的防止轻质小直径钻杆在钻孔中晃动，其减振装置由内嵌式钻杆连接件、轴承结构、锁紧垫片和支撑座组成。此种深孔钻进装置可保证小型钻机配合轻质小直径钻杆在深孔钻机过程中的稳定高效，具有较好的推广前景。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model relates to a deep hole drilling device. The utility model belongs to the technical field of rock mass drilling. The device comprises a large-diameter drill bit, a drill rod connecting piece, a damping device and a light small-diameter drill rod, the large-diameter drill bit is arranged at the top end for drilling; the large-diameter drill bit is in threaded connection with the light small-diameter drill rod; the drill rod connecting piece is arranged between the light-weight small-diameter drill rods and can connect the light-weight small-diameter drill rods into a whole; ata proper position, the vibration damper replaces part of the drill rod connecting piece to be arranged between the light small-diameter drill rods, the diameter of the vibration damper is slightly smaller than that of the large-diameter drill bit, the light small-diameter drill rods can be effectively prevented from shaking in a drilled hole, and the vibration damper is composed of an embedded drill rod connecting piece, a bearing structure, a locking gasket and a supporting base. The deep hole drilling device can ensure that a small drilling machine is matched with a light small-diameter drill rod to be stable and efficient in the deep hole drilling process, and has a good popularization prospect.
