The invention relates to the technical field of fuel overhauling, and discloses a nuclear power new fuel assembly overhauling gripping apparatus and a gripping method thereof.The nuclear power new fuel assembly overhauling gripping apparatus comprises a power mechanism, and the power mechanism further comprises a fixing plate. A fuel assembly needing to be detected is lifted through a lifting appliance and penetrates through an air pressure ring pipe, the fuel assembly is placed at the top of a rotating ring, at the moment, the high-quality fuel assembly presses a pressed plate to move downwards, and air in a pressed air groove enters an air storage box through a conveying air pipe under extrusion of the pressed plate; and gas in the gas storage tank enters the inner wall of the sliding pipe to force the pushing disc to move outwards, in the outward moving process of the pushing disc, the inclined rolling wheel is pushed by the pushing disc to make contact with the outer wall of the fuel assembly, and when the output rod and the inclined rolling wheel extend outwards, the output rod and the inclined rolling wheel are attached to the square shape of the fuel assembly.

    本发明涉及燃料检修技术领域,且公开了一种核电新燃料组件检修抓具及其抓取方法,包括动力机构,所述动力机构还包括有固定板,本发明利用燃料组件自身高质量的特点,在设备内部设置有受压气槽,在工作人员需要检修时,将所需检测的燃料组件通过吊具将组件提起,并穿过气压环管,将燃料组件放置在旋转环顶部,此时高质量的燃料组件压迫受压板向下移动,受压气槽内部空气在受压板的挤压下,通过传输气管进入储蓄气箱内部,而储蓄气箱内部气体进入滑动管内壁,迫使推动盘向外移动,在推动盘外移的过程中,倾斜滚轮受推动盘的推动与燃料组件的外壁接触,其中输出杆与倾斜滚轮在外展时,将贴合燃料组件方正的外形。
