Anti-shearing telescopic anchor rod
The invention discloses an anti-shearing telescopic anchor rod, and relates to the technical field of anchor rods, the anti-shearing telescopic anchor rod comprises an anchor rod head, a telescopic rod and a tail end connecting rod which are rotationally connected in sequence, the telescopic rod is of a structure capable of stretching after being pulled, and the rotating center of the telescopic rod and the rotating center of the tail end connecting rod are both perpendicular to the axial direction of the telescopic rod; therefore, when surrounding rock deforms and generates large shearing force, the anchor rod head, the telescopic rod and the tail end connecting rod can generate relative rotation so as to counteract the influence generated by the shearing force. When the surrounding rock deforms to generate large pulling force, the telescopic rod can also extend in a matched mode to offset the influence generated by the pulling force, and therefore the problem that an existing anchor rod cannot effectively prevent shearing and stretching damage is practically solved.
本发明公开了一种抗剪切可伸缩锚杆，涉及锚杆的技术领域，包括依次转动连接锚杆头、伸缩杆和末端连杆，伸缩杆为受拉力后可伸展结构，且伸缩杆和末端连杆的转动中心均与自身轴向垂直；所以当围岩形变产生较大剪切力时，锚杆头、伸缩杆和末端连杆之间将可产生相对转动，以抵消此剪切力产生的影响；而当围岩形变产生较大拉扯力时，所述伸缩杆也能适配伸展以抵消此拉扯力产生的影响，从而切实解决了现有锚杆无法有效防止剪切和拉伸破坏的问题。
