AI Technical Summary

Technical Problem

Existing emergency separation devices suffer from problems such as incomplete separation, slow response speed, low reliability, poor safety, and limited applicability, failing to meet the safe, efficient, and reliable emergency separation requirements of modern industrial production.

Method used

The dual separation method combines electromagnetic cancellation and mechanical pushing. By using a combination of a strong magnetic coil and a rubber bladder, the electromagnet generates a reverse magnetic field to cancel the magnetism of the strong magnetic coil, and the mechanical pushing force of the rubber bladder pushes the strong magnetic coil completely into the inner hole, thus achieving complete separation of the workpiece.

Benefits of technology

It achieves complete separation of workpieces, with fast response speed, simple and reliable structure, wide range of applications, high safety, and can work stably in a variety of harsh environments, with a separation effect of 100%.

Abstract

This invention discloses a fault emergency separation device and its usage method, belonging to the field of mechanical emergency separation technology. The device includes an adsorption frame, a top mounting frame, and an auxiliary frame connecting the two. The lower surface of the adsorption frame has a rubber bladder with grooves and an internal skeleton, and a slidable strong magnetic ring is located inside. The lower surface of the top mounting frame has an electromagnet plate. The auxiliary frame contains an electromagnet and an iron sheet, and is surrounded by a pump body and an inner tube communicating with the rubber bladder. During normal operation, the strong magnetic ring extends to achieve stable adsorption; when the electromagnet is energized, it generates a reverse magnetic field to counteract the magnetism of the strong magnetic ring, while the pump body fills the rubber bladder with a medium, completely pushing the strong magnetic ring into the second inner hole to achieve thorough separation. This invention solves the problems of incomplete separation, slow response, and low reliability in existing technologies, and has the advantages of dual separation protection, rapid response, safety, and durability. It is widely applicable to emergency separation needs in fields such as industrial automation, robotics, and lifting and transportation.
