    • PURPOSE: An apparatus for changing a steam generator of a nuclear power plant is provided to improve the efficiency and the reliability of a steam generator changing by changing the steam generator without incising a wall of a hangar building. CONSTITUTION: An overhead crane(10) moving along a guiding rail(12) is installed on a ceiling of a containment building(100) and provided with a lifting beam(13). The overhead crane(10) is coupled to a working arm(14) that rotates a steam generator(120) when a trolley operates. A supporting unit(20) is provided on a side of the containment building(100) and maintains the steam generator(120) in horizontal when the lifting beam(13) of the overhead crane(10) and the working arm(14) operate. A conveying crane is installed on an upper of a supporting frame and moves along a guiding rail. The conveying crane is coupled to a working arm that holds the steam generator(120) to convey it to a following process. A control unit outputs an operation signal to the overhead crane(10) and the conveying crane to control a lifting of the lifting beam(13), a rotation of the working arm(14), and an operation of the trolley.
    • 目的:提供一种用于更换核电站蒸汽发生器的设备,以提高蒸汽发生器的效率和可靠性,通过改变蒸汽发生器而不会改变机库建筑物的墙壁。 构成:沿着导轨(12)移动的架空起重机(10)安装在容纳建筑物(100)的天花板上并且设置有提升梁(13)。 桥式起重机(10)联接到当手推车操作时使蒸汽发生器(120)旋转的工作臂(14)。 当架空起重机(10)和工作臂(14)的提升梁(13)操作时,支撑单元(20)设置在容纳建筑物(100)的一侧并将蒸汽发生器(120)维持在水平状态 。 输送起重机安装在支撑框架的上部并沿导轨移动。 输送起重机联接到工作臂,该工作臂保持蒸汽发生器(120)将其传送到后续过程。 控制单元向顶置起重机(10)和输送起重机输出操作信号,以控制提升梁(13)的提升,工作臂(14)的旋转以及手推车的操作。
