VIBRATION-RESISTANT AND WHOLE-LIFE BASIN-TYPE SPHERICAL STEEL SUPPORT FOR BRIDGE

The present disclosure discloses a vibration-resistant and whole-life basin-type spherical steel support for bridge, wherein: a column is fixedly connected to a middle part of a supporting frame, a movable sleeving fits and is movably connected to an outer curved surface of the column, a first spring is fixedly connected to an inner side surface of the movable sleeving, a connecting rod is in turning connection to an upper end of the movable sleeving, and a platform is in turning connection to an upper end of the connecting rod. In the present disclosure, two ends of the first spring are welded to inner sides of two movable sleevings, which fit and are movably connected to two sides of an outer curved surface of a single column; therefore, when the first spring is subject to the impulse force of vibrations, the first spring will absorb the impulse force of vibrations and compress inwards to be deformed; when the first spring absorbs the impulse force of vibrations and compress inwards to be deformed, an elastic potential energy will be generated by the deformation of the first spring, and will be reversely transmitted to the movable sleeving, thereby driving the movable sleeving to move left and right along the outer curved surface of the column welded at the middle part of the supporting frame, as a result, the role of absorbing the vibration force is played, and the all-round and further effect of vibration resistance is realized.
