TECHNICAL FIELD

[0001] The utility model relates to a conveying device technical field, concretely is a long distance belt conveyor protection device. BACKGROUND

[0002] As a commonly used material conveying equipment, the belt conveyor is widely used in the conveying of materials. The long distance belt conveyor is especially suitable for the transportation of bulk materials, and has the characteristics of long transportation distance, large transportation capacity and continuous transportation. However, with the increase of the conveying distance and the increase of the material load, especially the material with high gravity center, the belt conveyor is prone to deviation and falling during operation.

[0003] The traditional belt conveyor often lacks effective anti-deviation device, and cannot correct the deviation of the conveying belt in time. This leads to the deviation of the conveying belt from the track during operation, and even falling, which seriously affects its safety and stability. With the increase of the conveying length, the risk of material falling also increases. Therefore, a new long distance belt conveyor protection device is needed to provide an effective solution to the defects of the prior art. UTILITY MODEL CONTENT
