The invention discloses a variable lifting appliance for a radioactive waste packaging box. The variable lifting appliance for the radioactive waste packaging box comprises a main beam, an auxiliary beam, strut beams and a first adjusting mechanism, wherein the first adjusting mechanism comprises a screw rod, a first rotating hand wheel, a threaded sleeve and a rotating reversing assembly; a first containing cavity is formed in the main beam; one end of the auxiliary beam and one end of the lead screw are both located in the first containing cavity; the other end of the auxiliary beam and the other end of the screw rod are both connected with the strut beams; the first rotating hand wheel is arranged outside the main beam, a wheel handle of the first rotating hand wheel is inserted into the first containing cavity, the screw rod is sleeved with the threaded sleeve, the rotating reversing assembly is connected between the wheel handle and the threaded sleeve, and a fixing piece is further arranged in the first containing cavity and is rotationally connected with the threaded sleeve, so that a structure that the wheel handle rotates to drive the threaded sleeve to rotate and screw rod to move linearly is formed; and lifting hooks are arranged on the strut beams. The adjusting mechanism drives the strut beams located on the two sides of the main beam to move, so that the distance between the lifting hooks is adjusted, the length of the main beam in the direction is changed, and the size requirement of waste packaging boxes is met.

本发明公开了一种用于放射性废物包装箱的可变吊具，包括主梁、副梁、支梁、第一调节机构，第一调节机构包括丝杆、第一旋转手轮、螺套、转动换向组件，主梁内设置有第一容纳腔，副梁、丝杆的一端均位于第一容纳腔的内部，副梁、丝杆的另一端均连接支梁，主梁外部设置第一旋转手轮，第一旋转手轮的轮柄插入到第一容纳腔内，丝杆的外部套设螺套，轮柄与螺套之间连接转动换向组件，第一容纳腔内还设有固定件，固定件转动连接螺套，形成轮柄转动带动螺套转动、使丝杆直线移动的结构，支梁上设有吊钩。通过调节机构带动位于主梁两侧的支梁移动，进而调整吊钩间距，改变主梁方向的长度，适应废物包装箱的尺寸要求。
