[0002] Belt conveyor is a common material transportation method, widely used in coal mines, thermal power plants and industrial production. Coal is transported from one location to another by conveyor belts. It usually relies on electric motors to drive the rollers to drive the belts. It can transport large amounts of coal continuously and at high speed. Compared with other transportation methods, it has lower maintenance costs and can adjust the transportation routes and angles according to the site and needs.

[0003] In the production process of thermal power plants, coal mines and other industries, belts are used to transport raw coal over long distances. During the long-distance transportation of these raw coals, the belts often deviate and scatter coal. When the deviation is serious, it will cause belt damage or cause equipment failure, and even safety accidents, which will pollute the production environment, bring risks to the personal safety of workers, and bring safety hazards to safe production.

[0004] Therefore, we proposed a hyperbolic roller damper for preventing belt deviation in coal transportation, so as to solve the above-mentioned problems. Summary of the invention
