[0002] In the coal conveying power plant, the belt conveyor is an important equipment for material conveying, and is widely used in long-distance transportation of coal. Its main function is to convey coal from the storage area to the boiler or other processing equipment, ensuring the continuity and stability of fuel supply. However, due to the long conveying distance and complex operating environment, the belt conveyor is easily disturbed by external factors during operation, such as load change, tension fluctuation, wear of roller and support roller, etc., resulting in deviation of the conveying belt.

Therefore, how to design a limiting structure that can be flexibly adjusted, so that it can prevent the deviation of the conveying belt while having good adaptability and return function, is a problem to be solved in the current technical field.
