Reactor pressure vessel automatic checkout equipment's flange strutting arrangement

The utility model relates to an in -service inspection technical field, concretely relates to reactor pressure vessel automatic checkout equipment's flange strutting arrangement. The device includes flange switching part, four guide posts, four direction legs, and the concatenation of flange switching part is a circular ring seat, four fixed upper ends that are located flange switching part of guide post, guide post quartering circular ring seat, four fixed lower extremes that are located flange switching part of direction leg. Through using this strutting arrangement, avoided the check -out set to the sheltering from of threaded holes and seal groove, reached the effect that shortens unit repair time, improves economic benefits. 本实用新型涉及在役检查技术领域，具体涉及种反应堆压力容器自动检查设备的法兰支撑装置。该装置包括法兰转接部件、四个导向柱、四个导向腿，法兰转接部件拼接为个圆环座；四个导向柱固定位于法兰转接部件的上端，导向柱四等分圆环座；四个导向腿固定位于法兰转接部件的下端。通过使用该支撑装置，避免了检查设备对螺纹孔和密封槽的遮挡，达到了缩短机组检修时间、提高经济效益的效果。
