Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belt deviation prevention, in particular to a conveyor belt deviation prevention mechanism. Background Art

[0002] Thermal power plants need coal as energy to generate electricity, and the transportation of coal requires conveyor belts. At present, conveyor belts often deviate during operation due to the heavy weight of materials, long service life of conveyor belts, aging deformation, edge wear and other reasons. Once the conveyor belt deviates, it will bring more hazards: 1. Equipment damage: When the belt deviates, it may cause friction and damage to equipment components such as rollers, rollers, and roller frames, and even cause damage and failure of the equipment. 2. Safety hazards: Belt deviation will cause the conveyor belt to leave the track, causing unstable equipment operation, and there are safety hazards such as jamming and collision, which may cause harm to workers and equipment. 3. Production interruption: When the belt deviation causes equipment damage or safety problems, it is necessary to shut down for maintenance or adjustment, which will lead to interruption of the production line and delay of production plan. 4. Reduce equipment life: Frequent belt deviation will cause the equipment to continue to be unevenly stressed, accelerate the wear and damage of the equipment, thereby reducing the life of the equipment and reducing production efficiency. 5. Cause material waste: Belt deviation may cause materials to fall or leak from the conveyor belt, causing material waste and environmental pollution.

[0003] At present, there are structures that use guide rollers or correcting wheels to prevent deviation. When in use, the guide roller is set on one side of the conveyor belt to limit the conveyor belt and prevent it from deviation. However, the installation position of this roller or wheel must meet the limiting requirements, that is, it cannot be too close or too far away from the conveyor belt. Most of the existing anti-deviation structures of this type are installed as a whole, and it is difficult to ensure the position accuracy of the guide roller or the correcting wheel. Therefore, a conveyor belt anti-deviation mechanism with an adjustable wheel position is needed to avoid damage caused by deviation. Utility Model Content
