摘要： A gripping and lifting device, especially for use with fuel elements and control rod means in a nuclear core reactor in which a carriage having a winch thereon supports a mast beneath the carriage in which is slidable a tubular body within which, in turn, is slidable a housing. Cables lead from the winch to the first body for vertical movement thereof while the housing has limited axial movement in the aforementioned body. On the lower end of the housing are two gripper devices, one for engagement with the control rods and the other for engagement with the fuel element. Separate actuators are provided for the two grippers and sensing devices are included in the structure for sensing the positions of the grippers. A feature of the arrangement is that when the body is elevated and the housing moves downwardly therein to a stopped position, the gripper for the fuel element is locked in its respective position.

摘要： A device for gripping bundles of control bars or rods for extracting the control bars from and introducing the control bars into fuel cells of nuclear reactors in which the control bars are in bundles connected by a spider-like head at the top and the gripping device includes a plate with a perforation through which the head can pass. When the head is released from the fuel cell and lifted upwardly through the plate, the plate provides lateral guidance for the control rods thereby facilitating replacement of the control rods into a fuel cell. The gripping device includes a reciprocable gripper body in a gripper tool detachably connectable thereto and to said head and guided on said plate by guide members projecting from the plate.
摘要翻译：一种用于夹紧控制杆或杆的装置，用于将控制杆从控制杆抽出并将其引入到核反应堆的燃料电池中，其中控制棒通过顶部的蜘蛛状头连接在一起并且夹持装置包括具有头部穿过的穿孔板。当头部从燃料电池释放并且向上提升穿过板时，该板为控制杆提供侧向引导，从而便于将控制杆更换为燃料电池。夹持装置包括可拆卸地连接到其上的夹持器工具中的可往复运动的夹持器主体，并且通过从板突出的引导构件在所述板上引导。
