AI Technical Summary
Existing mine support devices are prone to shifting under mechanical vibration, causing edge ore to fall. There is a lack of devices that can maintain support and enhance friction when shifting.
A temporary support device for tunneling construction was designed. The translation plate and the rotating shaft are fixed by the release rod. The elastic force impacts the edge of the hole to cause the crushed stone to fall off. The falling stone is caught by the airbag. The rotating plate and the extension plate increase the anti-slip effect.
The effective fixing of the rotating shaft and translation plate enhances the friction at the edge of the hole, prevents ore from falling, and improves the stability and anti-slip performance of the support device.
