Tension type locking anchor rod and using method thereof
The invention discloses a tension type locking anchor rod and an using method thereof. The tension type locking anchor rod comprises an anchor rod assembly, a tensioning assembly and an anchor head assembly. The tensioning assembly comprises a sleeve, a supporting tensioning rod, a positioning sleeve and an adjusting nut. The sleeve moves left and right on the left portion of a anchor rod body, the left end of each supporting tensioning rod is rotationally installed on the sleeve, and the right ends of the supporting tensioning rods which are evenly arranged in the circumferential direction are gathered and tightened through the bandage. The adjusting nut is installed on the anchor rod body in a threaded mode. The anchor rod body is sleeved with the positioning sleeve in a sliding mode, and when the sleeve and the positioning sleeve move relatively, the multiple supporting tensioning rods are expanded through the positioning sleeve, and one end of each supporting tensioning rod makes contact with the inner wall of a drill hole. The anchor head assembly comprises a fixing head and a second spring; the left end of the anchor rod body moves left and right and is limited in a blind cavity at the right end of the fixing head; when the second spring is compressed, one end is contacted with the fixing head, and the other end is contacted with the sleeve. According to the tension type locking anchor rod, structure is simple, expansion self-locking of the anchor rod in the drill hole can be effectively achieved, anchoring force is improved, and the tension type locking anchor rod is more stable and reliable.
一种涨紧式锁紧锚杆，包括锚杆组件、涨紧组件和锚头组件；涨紧组件包括套筒、支撑涨杆、定位套和调节螺母；套筒左右移动在锚杆杆体左部，每个支撑涨杆的左端转动安装在套筒上，绑带将多个圆周均匀布置的支撑涨杆的右端聚拢绑紧；调节螺母螺纹安装在锚杆杆体上；定位套滑动套装在锚杆杆体上，套筒与定位套相对移动时，定位套将多个支撑涨杆涨开并使支撑涨杆的一端与钻孔内壁接触；锚头组件包括固定头和第二弹簧，锚杆杆体的左端左右移动并限位设置在固定头右端的盲腔内；当第二弹簧压缩时时，其一端与固定头接触、另一端与套筒接触。本涨紧式锁紧锚杆，结构简单，能够有效实现锚杆在钻孔内涨开自锁，提升锚固力，更加稳固可靠。
