Sleeve overlapped multi-stroke sliding type anchor rod
The invention discloses a sleeve overlapping multi-stroke sliding type anchor rod which comprises an anchor rod body, the anchor rod body is divided into an inner anchor section and an outer anchor section, and a tray, a tray fixing piece, an energy absorption element and a damper fixing piece are sequentially installed on the outer anchor section rod body in the direction from the inner anchor section to the outer anchor section. The periphery of the inner anchor section rod body is sleeved with an inner sleeve, the end, close to the outer anchor section, of the inner anchor section rod body extends out of the inner sleeve, the end, close to the outer anchor section, of the inner sleeve is sleeved with an outer sleeve, the end, close to the outer anchor section, of the outer sleeve extends out of the inner sleeve, and the extending end of the outer sleeve is connected with the tray through a tray fixing piece. The inner anchor section and the outer anchor section of the anchor rod are both provided with the energy absorption components, on the basis that high anchoring force is guaranteed, the energy absorption components remarkably enhance the deformation capacity of the anchor rod so as to adapt to disasters such as large deformation and power impact of high-stress rock mass, structural resistance increasing sliding is achieved, it is guaranteed that the rod body stroke meets the working condition requirement to the maximum extent, and the service life of the anchor rod is prolonged. And the safety of constructors and production facilities can be protected.
本发明公开了一种套筒叠合多行程滑移式锚杆，包括锚杆本体，所述锚杆本体分为内锚段和外锚段，所述外锚段杆体从内锚段往外锚段方向顺次安装托盘、托盘固定件、吸能元件、阻尼器固定件，所述内锚段杆体外周套有内套筒且内锚段杆体靠近外锚段端从内套筒伸出，所述内套筒靠近外锚段端套有外套筒且外套筒靠近外锚段端从内套筒伸出，所述外套筒伸出端与托盘通过托盘固定件连接。本发明的锚杆内、外锚段均设置吸能构件，在确保高锚固力的基础上，吸能元件显著增强了锚杆的变形能力，以适应高应力岩体的大变形和动力冲击等灾害，实现结构增阻滑移和最大程度保证杆体行程满足工况要求，可保护施工人员和生产设施的安全。
