Abstract

The invention discloses a whole passive broken belt protection device and method for a belt conveyor. It is composed of wedge and turning linkage mechanism. The conveyor belt is controlled by the turning linkage mechanism set between the upper and lower turning mechanisms. When the conveyor belt is running normally, the turning mechanism maintains balance under the action of the counterweight and the pressing force of the conveyor belt; when the conveyor belt breaks , because the conveyor belt pressure disappears and the balance is broken, the counterweight plate and the counterweight block deflect to generate torque, so that the upturning and downturning mechanisms respectively form self-locking with the upper and lower self-locking wedges, and the broken belt is clamped and braked. The invention has the advantages of simple structure, convenient use, rapid response, simple reset, reliable capture, and convenient maintenance, and is especially suitable for integral binding of belt conveyor belts in underground mines, and is also suitable for other belt conveyors.

Description
