Abstract

The invention relates to a dismounting device and a dismounting method for a shaft. The dismounting device comprises a lengthening bar, a clamping and locking device, a hydraulic lifting part and a mobile supporting seat, wherein the lengthening bar is inserted into a shaft head opening of the dismounted shaft; the clamping and locking device is clamped on the outer surface of the lengthening bar;the hydraulic lifting part is a pressure supporting part, and a piston rod of the hydraulic lifting part is fixedly connected to the clamping and locking device; and the hydraulic lifting part is fixedly mounted on the mobile supporting seat. The dismounting device and the dismounting method for the shaft solve the problem of low maintenance efficiency, relatively high labor cost and low operating safety in the prior art.

Description

technical field [0001] The invention relates to a metallurgical equipment maintenance technology, in particular to a device and method for disassembling and assembling a shaft. Background technique [0002] In recent years, metallurgical manufacturing and related equipment technology have developed rapidly. With the continuous replacement and optimization of the metallurgical industry in the metallurgical market environment, the design technology of metallurgical processes, metallurgical equipment and processing equipment has also been continuously updated. During the construction process, the metallurgical technology, process Requirements and requirements for the quality of metallurgical finished products have also increased, and the disassembly and assembly of shaft parts is one of the problems that needs to be overcome urgently. Hearth rolls are large diameter bottom rolls used in continuous annealing lines. In the prior art, the shell of the cold-rolled annealing furnac...
