Pipe disassembling and assembling tool for direct-current transformer valve side sleeve

The invention belongs to the technical field of transformer manufacturing processes, and particularly relates to a direct-current transformer valve side sleeve pipe disassembling and assembling tool which comprises a shackle. The end part of the shackle is connected with a connecting belt in a sliding manner; the top ends of the pair of connecting belts are fixedly connected with a convex block and a concave block respectively; the convex blocks and the concave blocks can be spliced with each other; a limiting plate is hinged to the top end of the concave block; a first limiting groove is formed in the top end of the protruding block. The limiting plate is inserted into the first limiting groove. By means of the splicing effect of the convex blocks and the concave blocks, the valve side sleeve can be fixed, and the phenomena that the valve side sleeve slides in the carrying process, the valve side sleeve falls off, equipment is damaged, and workers are harmed are reduced. 本发明属于变压器制造工艺技术领域，具体的说是一种直流变压器阀侧套的管拆装工
