The invention relates to the technical field of nuclear engineering equipment, in particular to an underwater gripping device for small-diameter radioactive tubes, and adopts the technical scheme that the underwater gripping device for the small-diameter radioactive tubes comprises a gripping clamp, a hollow connecting rod, a gripping hook body arranged at the lower end of the connecting rod and capable of elastically resetting, a to-be-grabbed pipe can be clamped under the condition that the grabbing hook body is closed; the adjusting platform is provided with a transverse moving mechanism and a longitudinal moving mechanism, the transverse moving mechanism is used for driving the grabbing clamp to move transversely, and the longitudinal moving mechanism is used for driving the transverse moving mechanism to move longitudinally; and a lifting assembly is arranged on a frame body of the lifting frame in a matched mode, and the lifting assembly is used for lifting the grabbing clamp upwards. According to the underwater grabbing device for the small-diameter radioactive pipe, the pipe can be prevented from falling off, and accurate positioning of the grabbing clamp can be achieved; therefore, the small-diameter radioactive tube can be grabbed and transferred underwater at the corresponding depth, and the device has the advantages of being high in action precision and safe to operate.

    本发明涉及核工程设备技术领域,具体涉及一种小直径放射性管材水下抓取装置,技术方案为,一种小直径放射性管材水下抓取装置包括:抓取夹具,设置有中空的连接杆,所述连接杆下端设置有弹力复位的抓钩体,在所述抓钩体闭合的情况能够夹持待抓管材;调节平台,设置有横移机构和纵移机构,所述横移机构用于驱动所述抓取夹具横移,所述纵移机构用于驱动所述横移机构纵移;吊装架,于架体上适配有提升组件,所述提升组件用于向上提升所述抓取夹具。本发明提供的小直径放射性管材水下抓取装置,能够避免管材掉落、能够实现抓取夹具的精准定位;从而能够在水下相应深度抓取小直径放射性管并转移,具有动作精度高、操作安全的特点。
