Supporting force arm type hydraulic expansion anchor rod
The invention discloses a supporting force arm type hydraulic expansion anchor rod which comprises a supporting force arm, a hydraulic oil cylinder, a tie bar, two soil squeezing steel sheets, an anchorage device, an anchoring plate and a fixed hinge support, the two ends of the supporting force arm are hinged to the two soil squeezing steel sheets through the fixed hinge support, and the piston rod end of the hydraulic oil cylinder is hinged to the supporting force arm. One end of the tie bar is connected with the anchoring plate through an anchorage device, and the other end of the tie bar is connected with the supporting arm. According to the force supporting arm type hydraulic expansion anchor rod, due to the action of the force supporting arm, the expansion part of the anchor rod has large soil squeezing pressure on soil while having a large expansion range, the action of the hydraulic oil cylinder can be fully played, and the anchoring force of the anchor rod is remarkably improved.
本发明公开了一种撑力臂式液压膨胀锚杆，包括撑力臂、液压油缸、拉筋、挤土钢片、锚具、锚固板、固定铰支座，所述撑力臂两端通过固定铰支座分别与两片挤土钢片铰接，所述液压油缸的活塞杆端与撑力臂铰接，缸体底部通过固定铰支座与挤土钢片铰接，所述拉筋一端通过锚具与锚固板连接，另一端与撑力臂连接。本发明提供的一种撑力臂式液压膨胀锚杆，其撑力臂的作用，使锚杆的膨胀部分在拥有较大膨胀范围的同时，对土体具有较大的挤土压力，能充分发挥液压油缸的作用，显著提高锚杆的锚固力。
