Roll changing device for cleaning section of hot dip galvanizing unit

Abstract

The invention discloses a roll changing device for a cleaning section of a hot dip galvanizing unit. The device comprises a base with walking function, a lifting framework with lifting function, a sliding clamp part for changing a roll and a bracket for supporting the roll, wherein the sliding clamp part is arranged at one end of the upper surface of the lifting framework, and is in sliding connection with the lifting framework. The roll changing device clamps a shaft head of a sink roll through a concave hole of a clinch ear, detaches the roll to the bracket through a sliding trolley, and supports the roll through the bracket. Therefore, the device can realize convenient and quick roll changing, greatly reduce labor intensity and improve operation efficiency, is independent of the influence of a cement platform above, and avoids potential safety hazard.

Description

technical field [0001] The invention relates to roll changing equipment, more specifically, to a roll changing device in the cleaning section of a hot-dip galvanizing unit. The roll changing device can facilitate the replacement of the sinking roll under the cement platform in the cleaning section of the hot-dip galvanizing unit. Background technique [0002] The hot-dip galvanizing line is the production equipment for the important products of cold-rolling enterprises, and is responsible for the production of cold-rolled high value-added products. Several tanks with different functions are installed under the cement platform of the cleaning section at the entrance of the hot-dip galvanizing unit, and sinking rollers are installed at the bottom of the tanks for turning the strip steel, so as to remove the emulsion, dust and other impurities on the surface of the strip steel Rinse or electrolytic rinse. When these sinking rollers are used for a certain period of time, they n...

AI Technical Summary

Problems solved by technology

The whole process requires a large number of operators, high labor intensity, time-consuming and labor-intensive. Due to the high requirements for the continuity of the production of the hot-dip galvanizing unit, each roll change will greatly increase the downtime and seriously affect the production efficiency. In addition, in the long-term During the roll changing process, oil stains stuck to the working platform, and when the operator stood on the platform to work, the soles of his feet were easily slipped and fell, causing safety accidents

[0003] So far, the replacement of such sinking rollers is still completely done manually, and the problems of high labor intensity, long operation time, time-consuming, labor-intensive, low production efficiency and potential safety hazards have not been better resolved.
