Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically a belt conveyor deviation correction device. Background Technology

[0002] Belt conveying is a method of material transport that relies on the friction between the conveyor belt and the drive rollers. Its core components include the conveyor belt, idlers, and drive unit. The conveyor belt carries the material, the idlers provide support and reduce running resistance, and the drive unit provides power. It is widely used in mining, ports, building materials and other fields: transporting ore and coal in mines, transferring bulk cargo in port linkage equipment, and transporting coal in power plants. Its advantages are large conveying capacity, stability and efficiency, low energy consumption and convenient maintenance. Its disadvantages are fixed routes, requirements on material characteristics, limited tilt angles and large footprint. As an important mode of industrial transportation, it occupies a key position in large-scale material transfer due to its reliability.

[0003] Currently, in the use of belt conveyors, self-aligning idlers are needed to correct belt misalignment and prevent the belt from slipping during material transport, which would affect the transport of materials. Self-aligning idlers usually rely on the friction generated by the belt itself when it slips as power to rotate. The self-aligning idlers themselves do not have a power drive device. Therefore, when transporting and transferring self-aligning idlers, workers need to use tools such as straps to fix them to prevent the idler bracket from rotating during transport and transfer, colliding with other objects and causing damage. However, fixing the self-aligning idlers with straps is time-consuming, labor-intensive, and not conducive to the use of self-aligning idlers. Utility Model Content

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a belt conveyor misalignment correction device. It solves the problem that self-aligning idlers typically rely on the friction generated by the belt misalignment itself to rotate, as the idlers themselves lack a power drive. Therefore, during transport and transfer, workers need to use straps or other tools to secure the idlers to prevent them from rotating and colliding with other objects, causing damage. Furthermore, securing the idlers with straps is time-consuming, labor-intensive, and detrimental to their usability.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a belt conveyor deviation correction device, including a self-aligning mounting frame, a roller bracket rotatably mounted on the upper surface of the self-aligning mounting frame, three rollers rotatably mounted on the inner wall of the roller bracket, and a mounting plate fixedly mounted on the front surface of the self-aligning mounting frame; An auxiliary limiting mechanism is installed on the mounting plate. The auxiliary limiting mechanism includes a U-shaped plate and two top blocks. An adjustment groove is opened inside the mounting plate. The U-shaped plate is slidably installed on the inner wall of the adjustment groove. The two upper ends of the U-shaped plate slide through to the upper surface of the mounting plate. The two top blocks are fixedly connected to the two upper ends of the U-shaped plate respectively. A screw is rotatably installed on the inner wall of the adjustment groove. The U-shaped plate is threadedly connected to the screw. An installation groove is also opened inside the mounting plate. The lower end of the screw rotatably passes through the interior of the installation groove.

[0006] Preferably, the auxiliary limiting mechanism further includes two rubber pads, which are respectively fixedly installed on the rear surfaces of the two U-shaped plates.

[0007] Preferably, a rotating rod is rotatably mounted on the front surface of the mounting plate, and the rear end of the rotating rod rotatably penetrates into the interior of the mounting groove. Both the rear end of the rotating rod and the lower end of the screw are fixedly mounted with bevel gears, and the two bevel gears mesh with each other.

[0008] Preferably, a throttle handle is fixedly installed at the front end of the throttle rod.

[0009] Preferably, the mounting plate has an annular groove inside corresponding to the position of the rotating rod, and an annular plate is rotatably installed inside the annular groove, with the annular plate fixedly connected to the rotating rod.

[0010] Preferably, both ends of the self-aligning mounting bracket are fixedly connected to connecting plates.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a belt conveyor belt misalignment correction device, which has the following beneficial effects: This belt conveyor misalignment correction device, by rotating the handle, causes the U-shaped plate to move the two top blocks up and down, which can limit the rotation angle of the idler bracket, prevent free rotation caused by vibration during transportation, and use rubber pads to reduce rigid collisions between metal parts. This makes it easier and faster to limit the movement between the self-aligning idler groups, thereby improving the work efficiency of the staff and the conveying efficiency of the self-aligning idlers.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a new technical solution: a belt conveyor deviation correction device, including a self-aligning mounting frame 1, a roller bracket 2 rotatably mounted on the upper surface of the self-aligning mounting frame 1, three rollers 3 rotatably mounted on the inner wall of the roller bracket 2, and a mounting plate 4 fixedly mounted on the front surface of the self-aligning mounting frame 1. An auxiliary limiting mechanism is provided on the mounting plate 4. The auxiliary limiting mechanism includes a U-shaped plate 5 and two top blocks 6. An adjustment groove 7 is provided inside the mounting plate 4. The U-shaped plate 5 is slidably installed on the inner wall of the adjustment groove 7. Both upper ends of the U-shaped plate 5 slide through to the upper surface of the mounting plate 4. The two top blocks 6 are respectively fixedly connected to the two upper ends of the U-shaped plate 5. A screw 8 is rotatably installed on the inner wall of the adjustment groove 7. The U-shaped plate 5 is threadedly connected to the screw 8. An installation groove 9 is also provided inside the mounting plate 4. The lower end of the screw 8 rotatably passes through the interior of the installation groove 9.

[0016] Furthermore, the auxiliary limiting mechanism also includes two rubber pads 10, which are respectively fixedly installed on the rear surfaces of the two U-shaped plates 5.

[0017] Furthermore, by rotating the throttle 13, the U-shaped plate 5 drives the two top blocks 6 to move up and down, which can limit the rotation angle of the idler bracket 2, prevent free rotation caused by vibration during transportation, and reduce the rigid collision between metal parts by the rubber pad 10. This makes it easier and faster to limit the self-aligning idler group, thereby improving the work efficiency of the staff and the conveying efficiency of the self-aligning idler.

[0018] Furthermore, a rotating rod 11 is rotatably mounted on the front surface of the mounting plate 4. The rear end of the rotating rod 11 rotates through into the interior of the mounting groove 9. Both the rear end of the rotating rod 11 and the lower end of the screw 8 are fixedly mounted with bevel gears 12, and the two bevel gears 12 mesh with each other.

[0019] Furthermore, a throttle 13 is fixedly installed at the front end of the lever 11.

[0020] Furthermore, an annular groove 14 is provided inside the mounting plate 4 at the position corresponding to the rotating rod 11. An annular plate 15 is rotatably installed inside the annular groove 14, and the annular plate 15 is fixedly connected to the rotating rod 11.

[0021] Furthermore, connecting plates 16 are fixedly connected to both the left and right ends of the self-aligning mounting bracket 1.

[0022] Furthermore, during the transportation of this deviation correction device, the idler bracket 2 on the self-aligning mounting frame 1 can rotate freely around its pivot point. Before transportation, its rotation needs to be restricted to prevent component shaking or collision. Turning the handle 13 drives the rotating rod 11 to rotate. The bevel gear 12 at the rear end of the rotating rod 11 meshes with the bevel gear 12 at the lower end of the screw 8, transmitting the rotational motion to the screw 8. When the screw 8 rotates, the U-shaped plate 5 slides upward along the adjusting groove 7. The two upper ends of the U-shaped plate 5 drive the two top blocks 6 and the rubber pad 10 to rise synchronously. When the U-shaped plate 5 rises to its highest position, the rubber pad 10 contacts the front surface of the idler bracket 2, limiting the rotational freedom of the idler bracket 2 through mechanical blocking, thereby limiting and fixing the idler bracket 2 during transportation.
