Description

Technical Field

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

[0002] Belt conveyor systems are used in almost all coal mines and coking coal washing production lines. In belt conveyors, the material landing point is not in the middle of the belt section; the head, tail, guide roller, intermediate frame, etc. are not installed correctly; the belt joint is not perpendicular to the belt centerline; the tension inside the belt is uneven; the roller is not flexible; the roller wear is inconsistent; there is material between the roller and the belt, etc., which can cause the belt to deviate. Belt deviation can cause material spillage, the belt conveyor cannot run at full load, and the belt is worn; it can cause accidents such as belt tearing and emergency stop. For example, a belt deviation correction device of the Chinese utility model with patent number CN218641768U cooperates with a roller and an arc track. When the roller frame rotates, the roller slides on the arc track. The roller and the support rod support the roller frame, increase the support points when the roller frame rotates, make the rotation of the roller frame more stable, and the roller cooperates with the arc track to share the force borne by the rotating shaft, so that the rotating shaft is not easy to deform and fail, and ensure the working effect of the device. Through the cooperation of the slot group and the slot, the rotating shaft can be directly placed in the slot, so that the rotating shaft is mounted on the side bracket and the connecting bracket. The slot group and the slot limit the rotation of the rotating shaft, the main roller and the auxiliary roller can rotate relative to the rotating shaft, and the installation of the main roller and the auxiliary roller is completed. When the main roller or the auxiliary roller is worn out and needs to be replaced, the rotating shaft can be directly taken out from the top of the slot for replacement, which greatly reduces the maintenance time and improves the work efficiency.

The correction roller and the belt cannot fit tightly. At this time, the correction effect of the device is affected, reducing the correction efficiency and easily causing the correction angle to deviate, causing secondary damage to the conveyor.
