Telescopic expanded end type anchor rod core cage
The invention discloses a telescopic end-expanding type anchor rod core cage which comprises an axial rod, a movable rib is further included, a power spring piece which elastically stretches out and draws back in the axial direction of the axial rod is movably arranged on the axial rod, one end of the movable rib is movably connected with the free end of the power spring piece, and the other end of the movable rib is movably connected with a positioning disc arranged on the axial rod. The power spring piece is movably provided with a power piece for driving the adjustable rib to move from the folding position to the expanding position. According to the anchor rod core cage, through the arranged combined structure of the power spring pieces and the adjustable ribs, the adjustable ribs are driven by a power room to move from the guard position to the expansion position, so that an expansion structure is formed at the end of the anchor rod, the contact area between the anchor rod and a rock-soil body is increased, and therefore when the anchor rod is subjected to pulling force and pulling force, the anchor rod is prevented from falling off. The resistance borne by the expanded portion of the anchor rod is larger, the bearing capacity of a single anchor of the anchor rod is improved, the cost of the equal-diameter anchor rod is reduced, and meanwhile the construction efficiency of the anchor rod is improved.
本发明公开了一种可伸缩扩端式锚杆芯笼，包括轴向杆：所述轴向杆上活动设置有沿其轴向弹性伸缩的动力弹簧件，还包括活络筋条，所述活络筋条的一端与动力弹簧件的自由端活动连接，另一端与设置在轴向杆上的定位盘活动连接，所述动力弹簧件上活动设置有驱动活络筋条由收拢位置运动到扩展位置的动力件。本发明中，该锚杆芯笼通过设置的动力弹簧件和活络筋条的组合结构，使其在动力间的驱动下使得活络筋条从守龙位置运动到扩展位置，使得锚杆端部会形成一个扩展结构，增大了锚杆与岩土体的接触面积，从而在受到拉力和拔力时，锚杆的扩大部位受到的阻力更大，提高了锚杆单锚的承载力，降低了等直径锚杆的成本，同时提高锚杆的施工效率。
