The anti-deviation device is installed on the belt conveyor by bolts passing through the through holes in the mounting side frame 2. The belt of the belt conveyor passes over the belt roller 7 and is positioned between the deviation switches 4. When the conveyor belt touches one of the deviation switches 4, the hydraulic electric telescopic rod 8 is activated, pushing the deviation correction bracket 5 and driving the roller adjustment frame 6. Slight angular rotation allows for correction and adjustment. The switch adjustment frame 3 and the idler roller adjustment frame 6 enable manual adjustment of the distance between the belt conveyor's deviation switch 4 and the belt idler roller 7, allowing the anti-deviation device to adapt to belt conveyors with belts of different widths and to adapt to changes in width caused by belt deformation after long-term use.

[0022] In this embodiment, the switch adjustment frame 3 includes a limiting frame 301, a switch outer frame 302, and a first turntable 303.

The front end of the first turntable 303 is inserted into the groove hole on the rear surface of the switch outer frame 302. The misalignment switch 4 is located inside the switch outer frame 302. When adjusting the distance between the misalignment switches 4 according to the belt width of the belt conveyor, the first turntable 303 in the threaded through hole of the limiting frame 301 is rotated to adjust the position of the switch outer frame 302 inside the limiting frame 301. The position of the misalignment switch 4 changes accordingly and is adjusted so that the upright of the misalignment switch 4 contacts the side of the belt.
