[0015] The technical solution of the utility model is further described below through the accompanying drawings and embodiments.

[0016] Example

[0017] like Figure 1As shown, an intelligent electronic deviation correction device for a belt conveyor is arranged on a frame 1, and a fixed beam 2 is arranged on the frame 1. The deviation correction device includes a belt deviation correction mechanism and a deviation detection mechanism, and the belt deviation correction mechanism includes a rotating support bracket 4, a belt roller, and an electric push rod 16. The belt roller is arranged above the rotating support bracket 4, and the rotating support bracket 4 is arranged above the fixed beam 2 and is rotatably connected to the fixed beam 2. A transmission shaft 20 is arranged in the middle of the bottom surface of the rotating support bracket 4, and the bottom end of the transmission shaft 20 passes through the fixed beam 2 downward and is rotatably connected to the fixed beam 2.

[0018] like Figure 2 As shown, a push rod box 3 is provided on the side of the fixed crossbeam 2, an electric push rod 16 is provided on the side of the fixed crossbeam 2 and is linked with the rotating support bracket 4, the electric push rod 16 is provided in the push rod box 3, and a traction plate 18 is provided below the fixed crossbeam 2, one end of the traction plate 18 is fixedly connected to the end of the transmission shaft 20, and the other end of the traction plate 18 is hinged to the connecting shaft 19, and the connecting shaft 19 passes through the movable groove 17 on the bottom surface of the push rod box 3 and is linked with the electric push rod 16. When the electric push rod 16 is started, it pushes the connecting shaft 19 to move in the movable groove 17, so that the traction plate 18 rotates, and drives the rotating support bracket 4 to rotate through the transmission shaft 20. The rotation amplitude of the rotating support bracket 4 is affected by the pushing distance of the electric push rod 16.

[0019] The belt rollers include a horizontal roller 6, a left roller 5 and a right roller 7. The horizontal roller 6 is arranged in the middle of the upper part of the rotating support frame 4. The left roller 5 and the right roller 7 are arranged on both sides of the horizontal roller 6. The left roller 5 and the right roller 7 are arranged at an angle respectively. The left end of the left roller 5 and the right end of the right roller 7 are respectively provided with a material stopper 8 with a gradually increasing diameter. The belt rollers rotate synchronously with the rotating support frame 4. The belt rollers can bear the belt, and the material stopper 8 has a certain function of preventing the belt from deflecting.

[0020] The deviation detection mechanism includes a control box 15 and two detection units arranged opposite to each other. The detection units are respectively fixed on both sides of the frame 1. The control box 15 is electrically connected to the detection unit and the electric push rod 16. The detection unit includes a detection fixing frame and a detector 14. The detection fixing frame includes a bottom flat connecting plate 9, a vertical connecting rod 12 and an inclined mounting plate 13. The detector 14 is fixed on the top of the inclined mounting plate 13. The two detectors 14 are respectively arranged on both sides of the belt. When the belt tilts in a certain direction, the detector 14 in that direction is triggered. The inclined mounting plate 13 is fixed on the top of the vertical connecting rod 12. The vertical connecting rod 12 is fixed on the top of the bottom flat connecting plate 9. The bottom flat connecting plate 9 is fixedly connected to the frame 1 through a plurality of U-shaped bolts 10 and nuts. The top of the U-shaped bolt 10 passes through the bolt mounting slot 11 on the bottom flat connecting plate 9, and the bottom of the U-shaped bolt 10 bypasses the frame 1. Different from the traditional fixing method of punching and positioning, the U-bolt 10 will not cause damage to the frame 1, and can realize flexible adjustment of the installation position of the detection fixing frame on the frame 1; compared with welding fixation, it has lower cost, higher installation efficiency and less impact on the frame 1.

[0021] The control box 15 is fixed on the outside of the frame 1 . A controller and a touch panel are arranged in the control box 15 . The touch panel, the electric push rod 16 and the detector 14 are all electrically connected to the controller. When the detector 14 is triggered by the skewed belt, a deviation degree signal is generated. After receiving the deviation degree signal, the control box 15 issues a pushing distance signal to the electric push rod 16. After receiving the pushing distance signal, the electric push rod 16 starts to rotate the rotating support bracket 4, and the belt roller forces the belt to return to the center, completing the first-level deviation correction action; if the detector 14 in the same direction is triggered again after completing the first-level deviation correction action, it means that the rotation angle of the rotating support bracket 4 is not enough, and the control box 15 commands the electric push rod 16 to push out a larger stroke, so that the rotating support bracket 4 rotates at a larger angle, completing the second-level deviation correction action; if the detector 14 in the opposite direction is triggered after completing the first-level deviation correction action, it means that the rotation angle of the rotating support bracket 4 exceeds the required angle, and the formation of the electric push rod 16 is manually fine-tuned through the touch panel at this time; if the detector 14 in the same direction is triggered for the third time after completing the second-level deviation correction action, it means that the deflection degree of the belt is too large, exceeding the operating range of the deviation correction device, and the control box 15 instructs the belt conveyor to stop and alarm, and the site is manually inspected. The controller, detector and electric push rod all adopt existing finished components, and the relevant circuit adopts the existing mature circuit layout.

[0022] Therefore, the utility model adopts an intelligent electronic deviation correction device for a belt conveyor with the above-mentioned structure, which detects the deviation degree of the belt through a detection unit and sends a deviation degree signal to the control box 15, and sends a pushing distance signal to the belt deviation correction mechanism through the control box 15. After receiving the pushing distance signal, the electric push rod 16 drives the rotating support bracket 4 to rotate through the connecting shaft 19 and the traction plate 18, thereby correcting the belt deflection, which can timely and effectively protect the operation safety of the belt and the entire machine, and reduce the edge wear caused by the belt deviation.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
