Abstract

The utility model discloses a belt conveyor broken belt protection device, two belt conveyor broken belt protection devices are symmetrically arranged in the transverse direction of a belt, one or more groups of belt conveyor broken belt protection devices are arranged, one group of belt conveyor broken belt protection devices is arranged every 5 meters in the running direction of the belt when the multiple groups of belt conveyor broken belt protection devices are arranged, and an accessory plate is arranged at the bottom of the belt conveyor broken belt protection device. A belt channel is arranged above the accessory plate, and the two sides of the belt penetrate through the belt channel. A cavity is formed in the position, above a belt channel, in the belt conveyor belt breakage protection device, the height of the cavity is increased from low to high in the normal conveying direction of a belt, a rolling body is arranged in the cavity, the diameter of the rolling body is larger than the minimum height in the cavity and smaller than the maximum height in the cavity, and the bottom of the rolling body makes contact with the belt. The rolling body is arranged in the cavity of the broken belt protection device of the belt conveyor, so that when the belt is broken, the downward sliding of the belt can be slowed down or stopped in time, and the risk of casualties of passengers or material loss is reduced.
