Anti-seismic full-life bridge basin-type ball steel support

According to the anti-seismic full-life bridge basin-type ball steel support, a cylinder is fixedly connected to the middle of a supporting frame, the outer curved surface of the cylinder is movably connected with a movable sleeve in an attached mode, the inner side face of the movable sleeve is fixedly connected with a first spring, and the upper end of the movable sleeve is rotationally connected with a connecting rod; the upper ends of the connecting rods are rotationally connected with platforms. The two ends of the first spring are simultaneously welded to the inner sides of the two movable sleeves which are movably connected with the two sides of the outer curved surface of the cylinder in an attached mode, so that when the first spring is subjected to vibration impulsive force, the first spring can absorb the vibration impulsive force and is compressed and deformed inwards, and when the first spring can absorb the vibration impulsive force and is compressed and deformed inwards, the first spring can be
