Description

Bolt dismounting sleeve Technical Field The disclosure relates to the technical field of mechanical equipment overhauling, in particular to a bolt dismounting sleeve. Background In mechanical equipment, bolts are one of the most widely used connecting pieces, and the convenience and efficiency of the disassembly and assembly operation directly influence the assembly and maintenance progress and quality of the mechanical equipment. Particularly in a crystallizer of a continuous casting machine, the structure of the crystallizer copper plate component has the particularity that the crystallizer copper plate and a supporting plate are connected through a double-thread bolt, one end of the double-thread bolt penetrates through a screw hole of the supporting plate and is fastened in a wire sleeve on the copper plate, a sealing piece, a flat pad and a disc spring are sequentially arranged at the other end of the double-thread bolt, the double-thread bolt is fastened by a nut, and the nut is screwed by a set moment to realize the stable connection of the copper plate and the supporting plate and the sealing of copper plate cooling water.
