Can be returned.

On the other hand, when the return of the belt 23 is delayed because the angle of the roller 611 is not appropriate when the belt 23 occurs in meandering, the user lifts the tip of the roller engaging portion 61 to feed the teeth of the hook member 621. And toothing of toothing member 631 are released.

At this time, the engagement member 631 is rotated toward the outside of the hook portion 62 around the first shaft 632.

Subsequently, in the state in which the roller engaging portion 61 is rotated about the hinge axis so that the roller 611 and the base 50 maintain an appropriate angle, the engagement member is directed toward the hook portion 62 about the first axis 632. The teeth 631 are rotated to engage the teeth of the hook member 621 and the teeth of the fitting member 631 with each other.

At this time, the engagement member 631 is fixed to a fixed position by the stopper 633 while being pressed downward by the load of itself and the load of the roller coupling portion 61 and the hook portion 62.

As described above, the present invention can further simplify the configuration of the meandering prevention device by fixing the hook portion using the engagement member having a simple structure.

Through the above process, the present invention rotates the base about the rotation axis according to the meandering direction of the belt when the meandering of the belt occurs so that the belt, the idler and the roller are kept perpendicular to each other to maintain the belt in its original position. Can be quickly returned.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

The present invention is applied to the technical field to prevent meandering of the belt when conveying a powder or agglomerate material such as coal using a conveyor system.
