[0013] The following will be described in detail with reference to the embodiments of the present utility model and the accompanying drawings. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The present utility model will be further described below with reference to the accompanying drawings and embodiments:

[0015] As Figures 1 to 2 shown, a belt anti-deviation idler bracket is installed on a frame. The frame includes a frame side rod 1 and a frame base 2, and includes: an idler bracket 3, on which an idler 4 and two special-shaped idlers 5 are rotatably arranged. The two special-shaped idlers 5 are placed on both sides of the idler 4 and are inclined upward to both sides. The bottom of the frame side rod 1 is fixedly provided with an adjusting seat 6. The two ends of the idler bracket 3 are slidably connected to the adjusting seat 6. Both sides of the bottom of the idler bracket 3 are rotatably connected with a sliding adjusting wheel 7. The two sliding adjusting wheels 7 are coaxial. The sliding adjusting wheel 7 is placed on the frame base 2, and a two-stage deviation switch 8 is fixedly provided at the top of the frame side rod 1.

[0016] Specifically, the sliding adjusting wheel 7 drives the idler bracket 3 to slide horizontally along the adjusting seat 6. When there is an included angle between the moving direction of the idler bracket 3 and the moving direction of the belt, the special-shaped idler 5 generates friction with the belt, causing the deviated belt to move towards the middle direction, realizing automatic anti-deviation of the belt.

[0017] It further includes: a locking splint 9 and an adjusting bolt 10. A horizontal sliding groove is provided on the adjusting seat 6. Threaded holes are respectively provided at both ends of the idler bracket 3. The locking splints 9 are respectively arranged on the outer side of the idler bracket 3 and the inner side of the adjusting seat 6. The adjusting bolt 10 passes through the bolt holes provided on the locking splint 9, the idler bracket 3 and the horizontal sliding groove provided on the adjusting seat 6 to fixedly connect the idler bracket 3 and the adjusting seat 6.

[0018] Specifically, when the belt conveyor is running normally, tighten the adjusting bolt 10 to fixedly install the idler bracket 3 on the frame. When the belt runs off track, loosen the outer nut of the adjusting bolt 10 so that the idler bracket 3 and the adjusting bolt 10 can make horizontal sliding along the horizontal sliding groove on the adjusting seat 6.

[0019] The side surface of the special-shaped idler 5 is a single-sheet hyperboloid, and the outer diameter of the special-shaped idler 5 first decreases and then increases from the inside to the outside.

[0020] The two-stage deviation switch 8 is in contact with the side of the belt, and the signal output end of the two-stage deviation switch 8 is connected to the driving device of the belt.

[0021] Specifically, the two-stage deviation switch 8 is a common device for detecting the deviation of the conveyor belt. Two different action angles can be set. When the first-stage action angle is reached, the two-stage deviation switch 8 emits a set of signals for warning. When the second-stage action angle is reached, the two-stage deviation switch 8 emits another set of signals for stopping the machine.

[0022] The working principle of the present utility model is as follows: Multiple anti-deviation idler brackets are provided on a belt conveyor. The two-stage deviation switch 8 automatically detects the deviation of the belt. When the deviation angle is greater than the first-stage action angle of the two-stage deviation switch 8, a set of signals is emitted for warning. Loosen the outer nut of the adjusting bolt 10, and the sliding adjusting wheel 7 drives the idler bracket 3 to move along the horizontal sliding groove of the adjusting seat 6 under force to realize automatic deviation correction of the belt. When the deviation angle is greater than the second-stage action angle of the two-stage deviation switch 8, another set of signals is emitted to stop the driving device of the belt, and the belt is manually corrected.

[0023] The above has described the present utility model in an exemplary manner with reference to the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various improvements are made by adopting the method concept and technical solution of the present utility model, or directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
