Technical Field

The invention relates to an automatic unhooking device.

Background

At present, when a pulled piece (rolling mill) on a steel rolling production line is replaced, an old pulled piece needs to be pushed out and removed, and then a new pulled piece (rolling mill) needs to be pushed in, and in the process, a pulled piece quick-change device needs to be connected with the pulled piece (rolling mill) to drive the pulled piece (rolling mill) to move. At present, the connection between a quick-change device of a pulled part and the pulled part (rolling mill) mostly adopts a clamping plate connection mode, the pulled part (rolling mill) needs to be stopped after moving in and out, and the pulled part (rolling mill) can be moved again after the clamping plate is jacked open by another set of device. The replacement mode has the advantages of multiple steps, long time consumption, complex equipment and high failure rate.
