AI Technical Summary
Technical Problem
When disassembling the rolls of a short-stress rolling mill, the gap between the rolls and the ground is too small, making it impossible to install the electromagnetic induction heater and posing a safety hazard.
Method used
Design a disassembly aid device including a V-shaped plate and a station plate. The V-shaped plate with a preset angle is stably connected to the station plate and the pull plate to stably support the roller and provide sufficient clearance for the electromagnetic induction heater to heat the bushing and labyrinth.
Benefits of technology
This achieves stable support for the rolls, prevents roll rolling, improves disassembly efficiency, and reduces safety risks.

Abstract
The utility model relates to the technical field of rolling mill rollers, in particular to a short-stress rolling mill roller dismounting auxiliary device which comprises a V-shaped plate and standing plates vertically connected with the bottoms of the two opposite sides of the V-shaped plate respectively to form a door-shaped structure, the bottoms of the other two opposite sides of the V-shaped plate are vertically connected with first pulling plates, and the two sides of each first pulling plate are connected with the two standing plates respectively. The bottom face of the V-shaped plate is further connected with a vertical second pulling plate, the bottom face of the second pulling plate is flush with the bottom face of the standing plate so as to make contact with the ground, and the bottom face of the first pulling plate is higher than the bottom face of the second pulling plate. The V-shaped plate with the preset angle is stably connected with the stand plate and the first pulling plate, so that short-stress rolling mill rollers with different diameters can be stably borne, the short-stress rolling mill rollers are stably supported to form large gaps with the ground, and the dismounting operation of a rolling mill roller shaft sleeve and a labyrinth is assisted.
