摘要：【中文】本申请实施例提供了一种桥梁的上限位活动球型支座，包括：上座板、下座板、球冠和两个限位调节装置；球冠设置在上座板和下座板之间，且与上座板和下座板滑动连接；两个限位调节装置设置在上座板上，沿上限位活动球型支座的纵向，两个限位调节装置位于球冠的两侧；限位调节装置能够沿上限位活动球型支座的纵向调节两个限位调节装置之间的距离，以限制上座板沿上限位活动球型支座的纵向相对于下座板滑动的最大距离。当在桥梁上设置了本申请实施例的上限位活动球型支座之后，可以减少使用钢轨伸缩调节器，由此，可以减小设置钢轨伸缩调节器对高速铁路桥梁的建设带来的不利影响，不仅降低了桥梁的建设成本，还降低了桥梁设计、施工难度。 【EN】The embodiment of the application provides an upper limit activity ball-type support of bridge, includes: the upper seat plate, the lower seat plate, the spherical crown and the two limit adjusting devices; the spherical crown is arranged between the upper seat plate and the lower seat plate and is connected with the upper seat plate and the lower seat plate in a sliding way; the two limiting adjusting devices are arranged on the upper seat plate and are positioned on two sides of the spherical crown along the longitudinal direction of the upper limiting movable spherical support; the limiting adjusting devices can longitudinally adjust the distance between the two limiting adjusting devices along the upper limiting movable spherical support so as to limit the maximum sliding distance of the upper seat plate relative to the lower seat plate along the longitudinal direction of the upper limiting movable spherical support. After the upper limiting movable spherical support is arranged on the bridge, the steel rail telescopic regulator can be reduced, so that the adverse effect of the steel rail telescopic regulator on the construction of the high-speed railway bridge can be reduced, the construction cost of the bridge is reduced, and the design and construction difficulty of the bridge is also reduced.
