Expansion type expanded-head bearing plate variable-diameter cage and anchor rod or pile foundation
The invention relates to an expansion type expanded-head bearing plate variable-diameter cage, which comprises an expansion type expanded-head bearing plate and a cage framework, and specifically comprises a release mechanism, at least two ring-shaped fixers, a plurality of connecting ribs, a plurality of vertical ribs, a central rod, a bearing plate, an expansion rod and a pin shaft; the lower end of the central rod is fixed with the bearing plate, a ring-shaped fixer sleeves the central rod and can slide, and one end of the release mechanism fixes a ring-shaped fixer and can enable the ring-shaped fixer to slide under the action of acting force; a number of vertical ribs surround the central rod, the first set of movable connecting ribs are movably connected with the upper ends of the vertical ribs and the joint on the circumference of the first ring-shaped fixer respectively, and the second set of movable connecting ribs are connected with the lower ends of the vertical ribs and the joint on the circumference of the second ring-shaped fixer respectively. A group of expansion rods surround the central rod, the lower ends of the expansion rods are movably connected with pin shafts around the bearing plate, the expansion rods are contracted and close to surround the central rod, and the expansion rods are opened to form an angle of 30 to 120 degrees with the central rod.
一种拓展式扩大头承压板变径笼，包括拓展式扩大头承压板和笼骨架，具体构件为释放机构、起码二个圈状固定器、若干连接筋条、若干竖筋、中心杆、承压板、拓展杆、销轴；中心杆下端与承压板固定，一个圈状固定器；套在中心杆上能够滑动，释放机构一端固定住一个圈状固定器并能使此圈状固定器在作用力作用下滑动；若干竖筋环绕中心杆，第一组若干活动连接筋条分别活络连接若干竖筋的上端与第一圈状固定器圆周的关节，第二组若干活动连接筋条分别连接若干竖筋的下端与第二圈状固定器圆周的关节；一组拓展杆环绕中心杆，且拓展杆下端与承压板周围销轴活络连接，拓展杆的收缩靠拢环绕中心杆，拓展杆的张开与中心杆成30‑120度角。
