Special-shaped hole grouting reinforcement anchor rod for supporting
The invention provides a special-shaped hole grouting reinforcement anchor rod for supporting. The special-shaped hole grouting reinforcement anchor rod comprises a tunneling mechanism, a reaming mechanism and an anchor tail mechanism, wherein movable blocks and limiting blocks are arranged on a secondary shaft; threads are arranged between the movable blocks and the limiting blocks on the secondary shaft; circular holes with internal spirals are formed in the lower ends of the movable blocks; the secondary shaft penetrates into the circular holes, and the threads on the secondary shaft and the circular holes with the internal spirals in the lower ends of the movable blocks work in a coordinated mode; the four movable blocks are evenly arranged on the front side of a fixed circular ring; four fixed blocks are evenly arranged on the rear side of the fixed circular ring; the fixed blocks are rotationally connected with driven connecting rods through rotating shafts A; the movable blocksare rotationally connected with driving connecting rods through rotating shafts C; and the other ends of the driving connecting rods are rotationally connected with the other ends of the driven connecting rods through rotating shafts B. The secondary shaft rotates to drive the movable blocks to move forwards, meanwhile, the driving connecting rods drive the driven connecting rods to be in a foldedstate, a main shaft rotates to drive the driving connecting rods and the driven connecting rods to rotate in the circumferential direction to form special-shaped holes, and the anchoring acting pointof the anchor rod is firm and reliable through the special-shaped holes and splitting grouting; and the supporting effect is greatly improved.
一种支护用异型孔注浆加固锚杆，包括掘进机构、扩孔机构、锚尾机构组成，在次轴上设置活动块及限位块，次轴上活动块和限位块之间设置为螺纹，活动块下端为带内螺旋的圆孔，次轴穿入圆孔且次轴上螺纹与活动块下端带内螺旋的圆孔协调工作，固定圆环前侧均匀设置四个活动块，固定圆环后侧均匀设置四个固定块，固定块与被动连杆通过转轴A转动连接，活动块与主动连杆通过转轴C转动连接，主动连杆另一端和被动连杆另一端通过转轴B转动连接；次轴转动带动活动块向前移动，同时通过主动连杆带动被动连杆呈现折叠状态，主轴转动带动主动连杆和被动连杆周向转动形成异性孔，依靠异性孔和劈裂注浆确保锚杆的锚固着力点牢固、可靠；大大提高支护效果。
