Description

Dismounting device for steel roller of cold rolling mill Technical Field The utility model relates to the technical field of dismounting devices, in particular to a dismounting device for a steel roller of a cold rolling mill. Background When the aluminum strip and the steel strip are processed, a cold rolling mill is needed to be used, after the cold rolling mill is used for a period of time, steel rollers are needed to be replaced, the rollers are heavy, a lifting device is needed to be used for lifting the rollers during installation and disassembly, the rollers and a base are matched precisely, the positions of the rollers need to be adjusted during installation and disassembly, when the positions of the rollers are adjusted, workers can directly adjust the positions of the existing rollers by hands, the hands are easy to be squeezed or crushed, and danger exists. Disclosure of utility model The utility model mainly aims to provide a cold rolling mill steel roller dismounting device, which solves the problems that in the prior art, when the cold rolling mill steel roller dismounting device is mounted and dismounted, a worker directly adjusts a roller by hand, and the hand is easy to be crushed or bruised. The utility model provides a cold rolling mill steel roller dismounting device which comprises a lifting belt for binding steel rollers and an overhead crane for regulating the lifting belt, and further comprises an auxiliary regulating device, wherein the auxiliary regulating device comprises a straight rod, one end of the straight rod is connected with an arc rod, the other end of the straight rod is fixedly connected with a switch, two ends of the arc rod are provided with jacks, inserting rods are connected in a sliding mode in the jacks, one ends, close to each other, of the two inserting rods are fixedly connected with an electromagnet, one ends, far away from each other, of the two inserting rods are connected with nuts through threads, and the electromagnet is connected with the switch and a power supply through a wire.
