The invention relates to the technical field of inspection after irradiation, in particular to a special lifting appliance and a lifting device for a target piece after irradiation. The special lifting appliance comprises a base body, a first clamping piece, a second clamping piece and a locking piece, the base body is used for connecting hoisting equipment; the first clamping piece is rotationally connected with the base body; the second clamping piece is rotationally connected with the base body; the locking piece is movably matched with the base body; in a working state, the first clamping piece and the second clamping piece respectively rotate to a first position and a second position under the action of self gravity so as to be respectively buckled on a hanging head of an irradiated target piece; the locking piece moves to a third position under the action of self gravity and is matched with the first clamping piece and/or the second clamping piece so as to form rotation limiting on the first clamping piece and/or the second clamping piece. The structure is simple, a stress system is simple, fault/abnormity analysis is facilitated, fault/abnormity elimination is facilitated, and the hoisting device is suitable for hoisting work in the radiation environment.

    本申请涉及辐照后检验技术领域,具体涉及一种用于辐照后靶件的专用吊具及吊装装置。该专用吊具包括基体、第一夹持件、第二夹持件和锁定件;基体用于连接起吊设备;第一夹持件与基体转动连接;第二夹持件与基体转动连接;锁定件与基体活动配合;工作状态下,第一夹持件和第二夹持件分别在自身重力作用下转动至第一位置和第二位置以分别扣接在辐照后靶件的吊头上,锁定件在自身重力作用下活动至第三位置并与第一夹持件和/或第二夹持件形成配合以对第一夹持件和/或第二夹持件形成转动限位。本申请结构简单,受力系统简易,利于故障/异常分析,利于故障/异常排除,适用于辐射环境下的吊装工作。
