[0002] Belt conveyor is a long-distance and large-span transportation equipment, which is widely used in the industrial field. It can efficiently transport materials between two points and has been widely used.

When the belt is displaced, it drives the round roller 9 to rotate in situ. The rotating round roller 9 can reduce the relative friction with the belt as much as possible, thereby reducing the wear on the belt; the outer wall of the U-shaped frame 7 is provided with a guide plate 10, and the guide plate 10 is inserted into the guide hole of the column 6; the center line of the guide plate 10 is aligned with the belt The conveying direction line of the machine 13 is vertical; the function of the guide plate 10 is to provide a guide for the displacement of the round roller 9 to ensure that it can reliably touch the edge of the belt, the axis line of the round roller 9 is a vertical line, and the round roller 9 is in contact with the side of the belt; a hole is provided on the side wall of the column 6, and an infrared rangefinder 8 is embedded in the hole, and the infrared transmitting end of the infrared rangefinder 8 points to the U-shaped frame 7; the infrared rangefinder 8 can monitor the position of the U-shaped frame 7 in real time, and then know the position of the round roller 9.

[0018] Actual use process: During the normal operation of the belt conveyor, the round roller 9 is continuously pressed against the edge of the belt with the cooperation of the spring 12; the infrared rangefinder 8 monitors the position of the belt edge in real time. If the infrared rangefinder 8 finds that the distance between it and the U-shaped frame is too short, it means that the belt is deviating at this time; the reset mechanism corresponding to the infrared rangefinder 8 that detects the shortened distance acts alone, and the motor 4 in the reset mechanism acts to drive the slider 2 to move horizontally, and drives the round roller 9 to move horizontally to the end. During this process, the parameters of the infrared rangefinder 8 are compared and recorded with the data of the pull-rope distance sensor 5, and the pull-rope distance sensor 5 automatically records the most prominent point detected by the infrared rangefinder 8. The data of the most prominent point is the most prominent point; the most prominent point detected by the infrared rangefinder 8 is the place where the belt deviates most seriously, and the motor reverses to drive the slider to move to the place where the deviation is most serious. The position positioning here is coordinated by the pull-rope distance sensor 5; after the round roller 9 moves to the most prominent point, the hydraulic cylinder 11 is actuated to push the U-shaped frame 7 forward, thereby driving the round roller 9 to push the most prominent point of the belt deviation to reset, until the distance parameter detected by the infrared rangefinder 8 is within the normal range, indicating that the belt has been successfully corrected and reset, the hydraulic cylinder is reset, and the round roller 9 continues to touch the edge of the belt for monitoring, waiting for the next deviation.
