Roll-changing device of horizontal type continuous annealing furnace and using method of roll-changing device

Abstract

The invention relates to a roll-changing device of a horizontal type continuous annealing furnace. The roll-changing device of the horizontal type continuous annealing furnace comprises a cylindrical clamp, one or two handles and a machine tool, wherein a roller way is fully distributed on the machine tool, the cylindrical clamp is arranged on the roller way of the machine tool, one end of the cylindrical clamp is provided with the handles, the other end of the cylindrical clamp is provided with a groove with convex cross section, three fastening bolt holes are formed in the bottom of the groove and are perpendicular to the axis of the cylindrical clamp, included angles among the three fastening bolt holes are 120 degrees, a lifting mechanism is arranged at the bottom of the machine tool, an anti-collision spacer is arranged at one end of the machine tool, the roller way is formed by one row of rollers, and each roller is of a structure which is thin in middle and thick at two ends. Compared with the prior art, the roll-changing device of the horizontal type continuous annealing furnace has the beneficial effects that the roll-changing device has the characteristics of simple structure, convenience for use, scientific principle and practicality, and effectively avoids centering difficulty in direct manual changing of the roller and clamping operation of a crane, the roller with certain temperature on the horizontal type continuous annealing furnace is rapidly disassembled and assembled, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of continuous annealing furnaces, in particular to a roller changing device for a horizontal continuous annealing furnace and a method for using the same. Background technique [0002] There are more than 140 furnace rollers in the horizontal continuous annealing furnace, including: water-cooled rollers, carbon sleeve rollers and steel rollers. Although the materials are different, the geometric dimensions are equivalent. Can be replaced with a unified roll changer. At present, the unified roller changer relies on the crane to hang the sling (counterweight) for replacement. Since the clamp is in the air and moves with the crane during the replacement, it is difficult to align and affect the working time. Sometimes when the rolls are changed uniformly, in order to save time, people often use the method of carrying them on the shoulders or pulling them by hand to replace them manually, which is very dangerou...

Problems solved by technology

At present, the unified roller changer relies on the crane to hang the spreader (counterweight) for replacement. Since the clamp is in the air and moves with the crane during the replacement, it is difficult to align and affect the working time.

Sometimes when the rolls are changed uniformly, in order to save time, people often use the method of carrying them on the shoulder or pulling them by hand, which is very dangerous.

In addition, if you encounter a roller with high temperature, you will be helpless
