Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In a specific embodiment, the belt deviation online detection device provided by the application comprises a support seat fixed on the side plate 3, a limit switch 11 fixed on the outer end of the support seat, a guide hole seat 8 fixed on the inner end of the support seat and having a guide hole, a guide rod 7 connected in the guide hole and movable along the guide hole, a stop wheel 5 connected to the inner end of the guide rod 7 and rotatable, and an alarm device electrically connected with the limit switch 11. The outward movement of the guide rod 7 can trigger the limit switch 11. The stop wheel 5 is installed between the side edge of the belt 2 and the side plate 3. When the belt 2 drives the stop wheel 5 to move outward to a distance before the stop wheel 5 is tangent to the extension surface of the side plate 3, the outer end of the guide rod 7 triggers the limit switch 11.

[0033] In the above structure, the belt deviation online detection device comprises the support seat, the limit switch 11, the guide hole seat 8, the guide rod 7, the stop wheel 5, and the alarm device.

[0034] The support seat is fixed on the side plate 3, and the support seat is perpendicular to the side plate 3. The limit switch 11 is fixed on the outer end of the support seat, that is, the side away from the belt 2.

[0035] The guide hole seat 8 is fixed on the inner end of the support seat, that is, the side close to the belt 2. The guide hole seat 8 has a guide hole, and the axis direction of the guide hole is along the direction of the support seat. The guide rod 7 is connected in the guide hole and movable along the guide hole.

[0036] The stop wheel 5 is connected to the inner end of the guide rod 7, and the stop wheel 5 is rotatable. The outward movement of the guide rod 7 can trigger the limit switch 11. The alarm device is electrically connected with the limit switch 11. After the outer end of the guide rod 7 triggers the limit switch 11, the alarm device issues an alarm to remind.

[0037] The stop wheel 5 is installed between the side edge of the belt 2 and the side plate 3. When the belt 2 moves outward, the belt 2 moves towards the stop wheel 5. After the stop wheel 5 contacts the belt 2, the stop wheel 5 starts to rotate, and at the same time, the stop wheel 5 drives the guide rod 7 to run in the guide hole seat 8 on the support seat. When the belt 2 drives the stop wheel 5 to move outward to a distance before the stop wheel 5 is tangent to the extension surface of the side plate 3, the outer end of the guide rod 7 triggers the limit switch 11. After the limit switch 11 is in place, the alarm device gives a pre-warning prompt, and the operator checks the actual situation of the belt 2 of the belt conveyor 1.

[0038] The belt deviation online detection device provided by the application can implement online dynamic detection on the operation of the belt 2 of the belt conveyor 1, effectively reduce the labor intensity of the operators and maintenance personnel, optimize the cleaning and maintenance time of the operators and maintenance personnel, reduce the quality hidden danger caused by the deviation and wear of the belt 2 of the belt conveyor 1, ensure the continuous and stable operation of the equipment, and improve the effective operation of the equipment.

[0039] The belt deviation online detection device is only a preferred scheme, and is not limited thereto, and targeted adjustment can be made according to actual needs to obtain different embodiments. In an initial state, the belt 2 has a set distance with the side plate 3, the contact distance between the side wall of the baffle wheel 5 close to the belt 2 and the side of the belt 2, and the anti-deviation distance between the outer end of the guide rod 7 and the limit switch 11. The sum of the contact distance and the anti-deviation distance is smaller than the set distance by a set safety distance.

[0040] In an embodiment, the distance between the belt 2 and the side plate 3 is 35 mm, that is, the set distance is 35 mm. When the belt 2 moves by more than 35 mm on one side, there is a hidden danger of wear. The baffle wheel 5 is installed at a distance of 25 mm from the belt 2, that is, the contact distance is 25 mm. When the belt 2 deviates by 25 mm, the belt 2 starts to contact the baffle wheel 5. The entire guide rod 7 moves in a working displacement of 0-8 mm, that is, the anti-deviation distance is 8 mm. When the belt 2 drives the baffle wheel 5 to move by 8 mm, the guide rod 7 triggers the limit switch 11. When the guide rod 7 triggers the limit switch 11, the belt 2 still has a safety distance from the side plate 3, preventing the limit switch 11 and the alarm device from being insensitive and causing a delay, which causes the belt 2 to contact the side plate 3, and is relatively safe and reliable.

The contact between the outer end of the guide rod 7 and the limit switch 11 is guaranteed by limiting the overall displacement, and the guide rod 7 is prevented from moving too outward to crush the limit switch 11, which is more safe and reliable.
