Water quenching tank equipment and roller changing device thereof

Abstract

The invention discloses a roller changing device. The roller changing device comprises a roller changing trolley located on one side of a wringing roller assembly, wherein the roller changing trolley is provided with a roller bearing platforms used for bearing wringing rollers, and rolling wheels are arranged at the bottom of the roller changing trolley. During roller changing operation, the roller changing trolley moves to one side of the wringing roller assembly; at the moment, the roller bearing platforms are aligned with a wringing platform in the wringing roller assembly, an operator moves the wringing rollers needing to be changed to the roller bearing platforms, and the wringing rollers are moved away through the roller changing trolley; manual hoisting is not needed in the changing process, so that the changing and transferring efficiency is improved, and the safety risk in the changing process is reduced. The invention further provides water quenching tank equipment comprising the roller changing device. The two ends of wringing rollers in the water quenching tank equipment are arranged in bearing seats, and translation sliding wheels are arranged at the lower parts of the bearing seats and can facilitate movement of the wringing rollers on a wringing platform, so that the changing efficiency of the wringing rollers is further improved. The invention further provides the water quenching tank equipment comprising the roller changing device. The water quenching tank equipment has the advantages.

Description

technical field [0001] The invention relates to the technical field of cold rolling equipment, in particular to a roll changing device. The present invention also relates to a water quenching tank equipment comprising the above-mentioned roll changing device. Background technique [0002] The squeeze roller is set in the water quenching tank behind the annealing furnace, and is used to squeeze the water marks on the surface of the strip. The working condition of this station is high temperature and less water on the strip surface. Dry friction is likely to occur on the surface of the squeeze roll and the surface of the strip, especially the edge of the strip is likely to cause excessive wear on the roll surface. When the squeeze roller is worn to a certain extent, the operator needs to replace it. [0003] In the prior art, the roller changing process needs to be replaced by manual high-altitude hoisting. The operation time of changing rolls is too long, an average repla...
