Movable bridge support
The invention belongs to the technical field of bridge supports, and particularly relates to a movable bridge support which comprises a base, a mounting cavity, an elastic plate, balls, a supporting column, a supporting plate, a moving mechanism and an assisting mechanism. The base is cylindrical, and the mounting cavity is formed in the base; the lower end in the mounting cavity is elastically connected with an elastic plate up and down through a spring; a ball is connected into the upper wall of the elastic plate in a rolling mode; a supporting column is arranged on the upper surface of the ball in a contact manner; the supporting column is cylindrical, the upper end of the supporting column is fixedly connected with a supporting plate, and the supporting column is arranged in the mounting cavity; and when the expansion plate is extruded, internal air pressure of the expansion plate can be conveyed into the elastic pipe, even if the bridge shakes seriously due to an earthquake, the elastic pipe is expanded, then a power assisting plate at the outer end of the elastic pipe is extruded, a friction force between the power assisting plate and the ball is greatly enhanced, limiting of the supporting column is further improved, therefore, the bridge main body and the support can be protected at the same time during the earthquake.
本发明属于桥梁支座技术领域，具体的说是一种活动型桥梁支座，包括底座，安装腔，弹性板，滚珠，支撑柱，支板，移动机构和协助机构；所述底座呈圆柱形，底座的内部开设有安装腔；所述安装腔的内部下端通过弹簧上下弹性连接有弹性板；所述弹性板的上壁中滚动连接有滚珠；所述滚珠的上表面接触设有支撑柱；所述支撑柱呈圆柱形，支撑柱的上端固定连接有支板，支撑柱设在安装腔内；当膨胀板被挤压时还会将其内部气压输送进弹性管中，即使得当由于地震导致桥梁抖动严重时会使得弹性管膨胀，进而对其外端的助力板进行挤压，即极大的增强助力板与滚珠之间的摩擦力，即进一步提高对支撑柱的限位，以便于在地震时对桥梁主体和支座同时进行保护。
