Novel expandable shell rock anchor rod device
The invention discloses a novel expandable shell rock anchor rod device which comprises an expandable shell. The expandable shell comprises at least two connecting feet, the connecting feet and a transverse connecting part integrally formed with the connecting feet and located at the front end are connected into a whole, and inclined planes inclining outwards from left to right are arranged on theinner sides of the connecting feet. A conic body is arranged between the two connecting feet of the expandable shell, the outer surface of the conic body inclines outwards from left to right, a threaded hole is formed in the conic body, a screw rod penetrates through the threaded hole of the conic body to form threaded connection, and the front end of the screw rod abuts against the transverse connecting part. When the screw rod is screwed forwards, the screw rod is blocked by the transverse connecting part at the front end, the conic body moves backwards along the thread trend on the screw rod, and the connecting feet are opened outwards in the backward moving process of the conic body. The anchor rod device is higher in integrity, better in firmness and higher in pulling resistance whenanchored into a hole in a rock wall.
本发明公开一种新型可膨胀外壳岩石锚杆装置，包括可膨胀外壳，可膨胀外壳包括至少两连接脚，连接脚通过与其一体成型且处于前端的横向连接部连接形成一体式构成，连接脚内侧具有自左向右向外侧倾斜的斜面，可膨胀外壳的两连接脚之间设置有锥形体，锥形体外表面自左向右向外倾斜，所述锥形体内具有螺纹孔，螺杆穿过锥形体的螺纹孔并形成螺纹连接，所述螺杆的前端顶在所述横向连接部上，拧动螺杆向前的过程中螺杆被前端的横向连接部阻挡，且所述锥形体沿着螺杆上的螺纹走势向后移动，所述锥形体向后移动的过程中向外撑开所述连接脚。该锚杆装置的整体性更强、牢固度更好，在锚固到岩壁上的孔洞内时抗拔能够更强。
