The invention relates to the technical field of steam turbines, in particular to a lifting device for steam turbine rotor maintenance, which comprises a protection box, a folding assembly arranged in the protection box in a penetrating manner, a pushing assembly movably arranged in the protection box in a penetrating manner, a group of moving and rotating assemblies fixedly arranged in the protection box in a penetrating manner, and a clamping assembly fixedly connected with the moving and rotating assemblies. The protection box has the beneficial effects that the clamping assembly can be protected and stored when the protection box is not used, and meanwhile, the clamping assembly is horizontally arranged in the protection box, so that the section of the protection box can be further reduced, and storage is facilitated; during use, the first air cylinder is started to rotate the clamping assembly to the outside of the protection box, a rotor is clamped through the clamping assembly, on the other hand, in the moving process of the clamping assembly, contraction of the protection box is synchronously achieved, the size of the device is reduced, clamping of the rotor by the clamping assembly is facilitated, and further, the clamping efficiency is improved. The device can be automatically reset through the first air cylinder.
本发明涉及汽轮机技术领域,特别是一种汽轮机转子检修用起吊装置,其包括保护箱、贯穿设置于保护箱的折叠组件、活动穿设于保护箱的推动组件、固定穿设于保护箱的一组移动转动组件,以及与移动转动组件固定连接的夹持组件。本发明的有益效果为在闲置时能对夹持组件进行保护收纳,同时夹持组件在保护箱内部为水平设置,进一步可以减少保护箱的截面大小便于存放;在使用时,通过启动第一气缸将夹持组件转动至保护箱外部,并通过夹持组件实现对转子夹持,另一方面在夹持组件移动过程中,同步实现对保护箱的收缩,减少本装置的体积,便于夹持组件对转子的夹持,进一步的,本装置能够通过第一气缸实现自动复位。
