Expansion type anchor rod convenient to assemble
The invention relates to the technical field of anchor rods, and discloses an expansion type anchor rod convenient to assemble, which comprises an anchor rod body, an anchor rod fixing sleeve head, a hole sealing tray and a locking nut, the anchor rod fixing sleeve head sleeves the head of the anchor rod body, the hole sealing tray sleeves the tail of the anchor rod body, and the locking nut is in threaded connection with the tail of the anchor rod body. An expansion piece is installed on the side portion of the anchor rod fixing sleeve head, an expansion supporting piece is connected with the anchor rod body in a clamped mode, an inclined face protruding ring is installed on the outer side of the anchor rod body, and when the anchor rod body moves forwards, the inclined face protruding ring makes contact with the expansion supporting piece, the expansion supporting piece and the expansion piece are folded, the expansion piece expands outwards, and the expansion supporting piece is located between the inclined face protruding ring and the expansion piece. The expansion supporting pieces provide additional support for the expansion pieces, so that the expandable range and strength of the expansion pieces are enlarged, the success rate of one-time fixing of the anchor rod and a rock hole is increased, the anchor rod is pushed into the rock hole all the time instead of being pulled outwards, and initial tensioning force is more conveniently established between the anchor rod and a rock wall.
本发明涉及锚杆技术领域，且公开了一种便于装配的膨胀式锚杆，包括锚杆杆体、锚杆固定套头、封孔托盘和锁紧螺母，锚杆固定套头套在锚杆杆体头部，封孔托盘套在锚杆杆体的尾部，锁紧螺母与锚杆杆体尾部螺纹连接，锚杆固定套头侧部安装有膨胀片，膨胀支撑片与锚杆杆体卡接，锚杆杆体外侧安装有斜面凸环，锚杆杆体向前移动时，斜面凸环与膨胀支撑片接触，膨胀支撑片与膨胀片折叠，膨胀片向外膨胀，膨胀支撑片位于斜面凸环与膨胀片之间，膨胀支撑片为膨胀片提供额外支撑，使得膨胀片的可膨胀范围和强度加大，提高了锚杆与岩孔一次固定的成功率，本方案的锚杆一直向岩孔内推进，而不是向外拔，更加便于锚杆与岩壁建立初始张拉力。
