[0029] In order to solve the technical problems in the background art, such as Figure 1-4As shown, this application provides a technical solution: a heavy-duty belt conveyor lower correction device, characterized as follows:

[0030] Mounting frame 1 serves as the basic support structure for this device, constructed from high-strength steel to ensure sufficient load-bearing capacity. A bearing seat 2 is located at the center of mounting frame 1. Bearing seat 2 is precision-cast and houses a high-performance bearing to reduce frictional resistance during rotation. Bearing supports 3 are equidistantly positioned on both sides of bearing seat 2, with a drive shaft 4 installed inside each support 3. Mounting holes are provided on the side walls of drive shaft 4 for connecting subsequent L-shaped connecting rods 13. Protective plates 5, made of moderately thick steel plates, are located on both sides of mounting frame 1 and have fixing holes for connecting the alignment device to the belt conveyor. Protective plates 5 are fixed to mounting frame 1 by bolts or welding, providing protection and support while preventing external debris from entering the device. A rotating shaft 6 is housed within bearing seat 2, with a mounting plate 7 connected to its top. Mounting plate 7 is made of high-strength alloy material and has an inverted V-shaped bracket 8 connected to it. The inverted V-shaped bracket 8 is designed to rotate under the drive of the rotating shaft 6, thus achieving the alignment function. A limiting plate 9 is mounted on the mounting frame 1, with one end extending towards the inverted V-shaped bracket 8. The end of the limiting plate 9 is inverted V-shaped and has an inclined surface 10 parallel to the inner wall of the inverted V-shaped bracket 8. This inclined surface 10 is designed to contact the inner wall of the inverted V-shaped bracket 8 when it rotates, thereby effectively limiting the rotation range of the inverted V-shaped bracket 8 and ensuring the stability of the device operation. Idler roller brackets 11 are located at both ends of the inverted V-shaped bracket 8 and are made of high-strength steel, on which horizontal idler rollers 12 are mounted. The horizontal idler rollers 12 are made of wear-resistant material and can withstand the huge pressure during the operation of the belt conveyor, while also providing support and guidance. One end of the L-shaped connecting rod 13 is installed in the mounting hole of the drive shaft 4, and the other end is connected to the vertical roller bracket 14. The vertical roller bracket 14 has a mounting groove 16 for accommodating the vertical roller 15. The vertical roller 15 is installed vertically and is located on both sides of the horizontal idler roller 12. The vertical roller 15 contacts the side wall of the belt. The design of the vertical roller 15 further ensures stable belt operation and prevents belt deviation. The transmission plate 17 is located at the bottom of the mounting frame 1 and is connected to both the rotating shaft 6 and the drive shaft 4. The transmission plate 17 rotates with the rotation of either the rotating shaft 6 or the drive shaft 4. The three transmission plates 17 are of equal length and parallel to each other, and their ends are connected by a connecting plate 18, forming a parallel linkage structure. This structural design effectively transmits power and ensures that all components of the device work in a coordinated manner.

[0031] In use, the inverted V-shaped end of the limiting plate 9, with its inclined surface 10 parallel to the inner wall of the inverted V-shaped bracket 8, allows for real-time detection of belt misalignment. When belt misalignment occurs, the contact position between the limiting plate 9 and the inverted V-shaped bracket 8 changes, triggering a correction action. The drive shaft 4, via the L-shaped connecting rod 13, moves the vertical roller bracket 14, adjusting the position of the vertical roller 15, thereby correcting the belt misalignment. The drive plate 17 is connected to the rotating shaft 6 and the drive shaft 4, forming a parallel linkage structure to ensure the stability and synchronization of the transmission.

[0032] Furthermore, the limiting plate 9 is L-shaped. The L-shaped design allows the limiting plate 9 to restrict the object in two directions, effectively preventing displacement. The bottom of the limiting plate 9 is connected to the mounting bracket 1 by bolts or other fixing methods. This connection method ensures the stability and reliability of the limiting plate 9, enabling it to withstand the force generated when the belt deviates from its intended path.

[0033] It should be noted that the mounting groove 16 is elongated and positioned on the vertical roller bracket 14. This design allows the vertical roller 15 to be adjusted within the mounting groove 16 along its length to accommodate belts of different widths. The vertical roller 15 is secured to the mounting groove 16 with bolts or pins. By loosening the bolts or pins, the vertical roller 15 can be moved along the length of the mounting groove 16 to adjust its position to accommodate belts of different widths. After adjustment, the bolts or pins are retightened to ensure the vertical roller 15 is firmly in place.

[0034] It is worth noting that the mounting frame 1 adopts an inverted U-shaped structure. This design not only provides sufficient space to accommodate the transmission plate 17 and the connecting plate 18, but also enhances the structural stability of the entire device. The inverted U-shaped mounting frame 1 effectively protects the internal transmission components and reduces the impact of the external environment on them. The transmission plate 17 is located at the bottom of the mounting frame 1 and is connected to the rotating shaft 6 and the transmission shaft 4, respectively. The three transmission plates 17 are of equal length and parallel to each other, and their ends are connected by the connecting plate 18 to form a parallel linkage structure. This design ensures the stability and synchronization of the transmission, improving the operating efficiency and reliability of the device.

[0035] It should be noted that the ribs 19 are in the form of a grid and are set on the guard plate 5. This design not only enhances the structural strength of the guard plate 5, but also provides additional support, ensuring that the guard plate 5 can withstand greater external forces during operation and reducing deformation and damage.

[0036] It should be noted that the angle of the inverted V-shaped bracket 8 is designed between 60 and 90 degrees. This angle range ensures that the bracket provides sufficient support while allowing it to rotate flexibly with the shaft 6, adapting to different belt misalignment conditions. The specific angle can be optimized according to actual working conditions and belt characteristics. The 60-90 degree angle range provides a good balance, ensuring both the structural strength of the inverted V-shaped bracket 8 and its flexibility during operation. A smaller angle can provide greater support, suitable for heavier belts or larger misalignment forces; a larger angle provides greater flexibility, suitable for lighter belts or smaller misalignment forces.

[0037] It is worth noting that the two L-shaped connecting rods 13 are symmetrically arranged about the radial axis of symmetry of the horizontal idler roller 12. This design ensures that the vertical roller supports 14 on both sides are subjected to uniform force, improving the stability and symmetry of the entire device and reducing vibration and wear caused by asymmetrical force. The symmetrical arrangement of the L-shaped connecting rods 13 ensures that the vertical rollers 15 on both sides remain synchronized when adjusting their positions, thus better accommodating belts of different widths. This design not only improves the ease of adjustment of the device but also ensures the flatness and stability of the belt during operation. The symmetrical arrangement also reduces device skew caused by uneven force on one side, extending the service life of the device and improving operating efficiency.

[0038] It is worth noting that the width of the mounting plate 7 is designed to be greater than the opening width of the inverted V-shaped bracket 8. This design ensures that the mounting plate 7 can stably support the inverted V-shaped bracket 8 and provide sufficient contact area, enhancing the stability and reliability of the overall structure. The wider design of the mounting plate 7 can effectively reduce deformation and damage caused by uneven stress on the inverted V-shaped bracket 8, ensuring the smoothness of the rotating shaft 6 during rotation. The wider mounting plate 7 can also provide better support, reduce vibration, and extend the service life of the device.

[0039] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
