[0002] Belt conveyors, as a commonly used material conveying equipment, play an important role in industrial production and mining transportation. However, conveyor belts often deviate during operation, which not only affects the normal transportation of materials but can also cause damage to the conveyor belt and equipment failure. Therefore, belt conveyor deviation correction devices are particularly important.

[0003] When using the existing active deviation-correcting device for belt conveyors, it is necessary to use a mounting frame to install the deviation-correcting device on the belt conveyor. Since the mounting frame of the current deviation-correcting device is integrally formed by welding, the width of the mounting frame cannot be adjusted. Therefore, during installation, belt conveyors of different widths need to be welded with corresponding mounting frames before the deviation-correcting device can be installed on the belt conveyor. This affects the installation efficiency of the deviation-correcting device. Therefore, it is necessary to design an active deviation-correcting device for belt conveyors. Summary of the Invention

[0028] The utility model is further described below with reference to the accompanying drawings and specific embodiments:

[0029] refer to Figures 1 to 4 The active deviation correction device of the belt conveyor includes: a fixed cylinder 1; a moving rod 2, which is slidably installed inside the fixed cylinder 1; a mounting plate 3, which is fixedly connected to the end of the moving rod 2; an adjusting mechanism 7, which is arranged at the lower end of the fixed cylinder 1; a support seat 9, which is fixedly connected to the middle position of the upper end of the fixed cylinder 1; a rotating shaft 10, which is rotatably connected to the inside of the support seat 9; a roller frame 5, which is installed on the upper end of the rotating shaft 10; an idler 6, which is rotatably installed inside the idler frame 5; a power mechanism 4, which is arranged at the front end of the fixed cylinder 1.

[0030] Specifically, the distance between the two mounting plates 3 is first adjusted according to the width of the belt conveyor. When adjusting, the adjusting mechanism 7 can be used to drive the two moving rods 2 to move inside the fixed cylinder 1. As the moving rod 2 moves, the distance between the two mounting plates 3 can be changed. This makes it convenient to adapt to belt conveyors of different widths, improves the practicability of the device, and makes it convenient for workers to install the correcting device, thereby improving the installation efficiency. After the mounting plates 3 are fixed on the belt conveyor, when the conveyor belt deviates, the power mechanism 4 works. Under the action of the power mechanism 4, the rotating shaft 10 can be driven to rotate inside the support seat 9, thereby driving the roller frame 5 to rotate. When the conveyor belt deviates to the left, the roller frame 5 rotates clockwise around the rotating shaft 10 by a certain angle, so that the roller frame 5 is not perpendicular to the running direction of the conveyor belt. The friction force of the roller 6 on the conveyor belt has a right component, and the conveyor belt is forced to move to the right and return to its original running position, thus achieving the purpose of active correction.

[0031] When the handle 703 is turned, the two threaded blocks 704 are respectively fixed to the movable rod 2, and the internal threads of the two threaded blocks 704 are opposite. When the handle 703 is turned, the two threaded blocks 704 can be driven to move under the action of the two-way threaded rod 702. As the two threaded blocks 704 move, the movable rod 2 can be driven to slide inside the fixed cylinder 1, thereby facilitating the change of the distance between the two mounting plates 3, which is conducive to the installation of the correction device.

[0032] A square hole 8 is provided on the lower end surface of the fixing cylinder 1 , and the upper end of the threaded block 704 is located inside the square hole 8 and is slidingly connected to the square hole 8 . During operation, the square hole 8 is provided to facilitate the movement of the threaded block 704 under the action of the square hole 8 .

[0033] The power mechanism 4 includes a rotating seat 401, a hydraulic telescopic rod 402 and a connecting rod 403. The front end of the fixed cylinder 1 is fixedly connected to the rotating seat 401, and the hydraulic telescopic rod 402 is rotatably connected inside the rotating seat 401. The protruding end of the hydraulic telescopic rod 402 is rotatably connected to the connecting rod 403. The connecting rod 403 is fixedly connected to the rotating shaft 10. When working, the hydraulic telescopic rod 402 works, and with the cooperation of the rotating seat 401 and the connecting rod 403, it can drive the rotating shaft 10 to rotate, thereby facilitating the rotation of the roller frame 5.

[0034] The circumferential surface of the support seat 9 is fixedly connected with a fixed plate 11, and a limiting hole 12 is provided on the upper end surface of the fixed plate 11. A limiting rod 13 is slidably connected inside the limiting hole 12, and the upper end of the limiting rod 13 is fixedly connected to the roller frame 5. When working, by setting the limiting hole 12 and the limiting rod 13, the limiting hole 12 and the limiting rod 13 can prevent the roller frame 5 from rotating excessively under the cooperation of the limiting hole 12 and the limiting rod 13.

[0035] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
