Expandable supporting type spiral combined ground anchor
The invention discloses an expandable supporting type spiral combined ground anchor which is characterized in that an upper anchor rod with an internal thread is rotatably connected with a supporting rod through a connecting column, and a fixedly-mounted arc-shaped connecting plate and a lower anchor rod are connected to the upper anchor rod through bolts; the pull rod with external threads is in threaded connection and transmission fit with the upper anchor rod with internal threads, the bottom of the pull rod is in contact fit with the upper end of the supporting rod, and the cable rope is wound on a circular shaft on the inner surface of the pull rod through a universal coupling; when the lower end of the pull rod moves to the upper end of the supporting rod, under the acting force of the pull rod 1, the supporting rod starts to rotate clockwise around the connecting column to be unfolded and form an angle theta with the axis of the lower anchor rod, and the larger the axial spiral transmission displacement of the pull rod along the upper anchor rod is, the larger the pretightening force in the cable rope is, and the larger the unfolding angle theta of the supporting rod and the axis of the lower anchor rod is. The ground anchor is reasonable and compact in structure, flexible in operation, stable in operation, high in efficiency, high in applicability and easy and convenient to adjust and operate.
本发明公开一种可展开支撑式螺旋组合地锚，所述地锚在带有内螺纹的上锚杆上通过连接柱可转动的连接支撑杆，固装的弧形连接板和下锚杆通过螺栓连接在上锚杆上，带有外螺纹的拉杆与带有内螺纹的上锚杆进行螺纹连接和传动配合，拉杆底部与支撑杆上端接触配合，缆风绳通过万向联轴器缠绕在拉杆内表面的圆轴上；当拉杆的下端移动到支撑杆的上端时，在拉杆1的作用力下，支撑杆开始绕连接柱顺时针转动，使其展开并与下锚杆轴线成θ角度，拉杆沿上锚杆轴向螺旋传动位移越大，缆风绳中的预紧力越大，支撑杆与下锚杆轴线的展开角度θ越大，提高地锚与土的锚固力，结构合理、紧凑，运行灵活，作业平稳、效率高，适用性强，调节操作简易方便。
