Belt-broken protector

The utility model relates to a belt-broken protector, which utilizes the frictional force generated by the gliding of the rubber belt along the incline direction as the driving source to accomplish the multiple-point brake on the rubber belt to prevent the great economic loss caused the broken rubber belt after a rubber belt is broken. The belt-broken protector can be also matched with the existing vertical roll to prevent the rubber belt from being bonded. The belt-broken protector is composed of a friction wheel, a driving member, a bracket and a brake block, etc. The belt can be broken at any position along the line of a conveying machine, the belt-broken protector can efficiently and reliably brake the rubber belt on a heavy-load section. The belt-broken protector is chiefly used for an uphill/downhill rubber belt conveyor of a mine, and can be also used for a ground rubber belt conveyor for conveying granular materials with a big inclination angle in a long distance.
