The invention belongs to the technical field of cranes, and relates to a rope traction type nuclear ring crane, in particular to a special ring crane responsible for hoisting various kinds of heavy equipment in a nuclear island. Nuclear ring suspension bridge type design is changed into supporting rod design, one end of each supporting rod is fixed to the top of a dome of a nuclear power station containment vessel, and the other end of each supporting rod is erected on a walking mechanism running on an annular rail. The span of the nuclear ring crane is reduced, and the structural strength is improved; horizontal movement of a trolley on a bridge frame is changed into variable-amplitude movement of a pulley block under traction of a steel wire rope, and the structural weight and the geometric dimension of the nuclear ring crane are reduced; and the weight and the size of the novel nuclear ring crane structure are reduced, the steel wire rope is adopted to bear variable-amplitude movement of the nuclear ring crane, and therefore the anti-seismic property of the nuclear ring crane can be effectively improved.
本发明属于起重机技术领域,涉及一种绳索牵引式核环吊,具体是一种负责吊运核岛内各种重型设备的特殊环形起重机。本发明将核环吊桥式设计改为撑杆设计,撑杆的一端固定在核电站安全壳穹顶顶部,另一端架于在环形轨道上运行的行走机构上。本发明减小了核环吊的跨度,增加了结构强度;将小车在桥架上的水平运动变为滑轮组在钢丝绳牵引下的变幅运动,减小了核环吊的结构重量、几何尺寸;本发明的新型核环吊结构重量、尺寸的减小以及采用钢丝绳承担核环吊的变幅运动能有效提升核环吊的抗震性能。
