Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyor equipment, and specifically relates to a belt correction device for a mining belt conveyor. Background Technology

[0002] Mining belt conveyors are used to transport materials such as ore, mineral powder, and iron concentrate. The complex transportation environment often leads to belt misalignment. Existing belt correction devices commonly employ mechanical rollers and hydraulic systems. The general principle is to adjust the belt tension to return it to its correct running track, ensuring stable material transport and reducing belt wear and material spillage.

[0003] Most existing belt alignment devices are welded to the frame of the belt conveyor. During use, it has been found that their adjustment effect is unsatisfactory, requiring disassembly and re-welding during subsequent maintenance. Furthermore, belt misalignment varies with changes in materials or different material discharge points, resulting in a lack of targeted effectiveness from the alignment devices. Additionally, most alignment devices only offer single-sided adjustment and lack dual-sided adjustment capabilities.

[0004] For example, utility model patent CN203889490U discloses a conveyor belt correction device. An upper column is fixed above the left end of a connecting rod, and a lower column is fixed below it. The right end of the connecting rod is fixed to a right column. A lead screw is located in the shaft hole of the right column, and an upper nut is screwed onto the lead screw. The upper nut is fixed to the lower end of an upper corner rod, which extends from the upper elongated slot of the right column and is hinged to the right end of a roller bracket. The left end of the roller bracket is hinged to the upper end of the aforementioned upper column, and a roller is hinged to the roller bracket. The upper end of the lead screw extends out of the right column and is fixed to the right column via a thrust bearing. A drive handle is located at the upper end of the lead screw. By adjusting the drive handle, the belt is subjected to force and returned to the correct running track, reducing belt wear and material spillage. Utility Model Content

[0021] Example 1

[0022] A belt correction device for a mining conveyor belt includes a rotating mechanism 2 and two symmetrically arranged adjusting mechanisms 3.

[0023] The rotating mechanism includes a rotating box 21 fixedly connected at both ends to the belt frame of the conveyor belt by brackets, a bidirectional threaded rod 22 disposed inside the rotating box with one end rotatably connected to the inner wall of the rotating box and the other end passing through the rotating box, two symmetrically arranged fixing blocks 23 threadedly connected to the bidirectional threaded rod, a rotating rod 24 located outside the rotating box and fixedly connected to the bidirectional threaded rod, and a rotating component 1 fixedly connected to the rotating rod.

[0024] The adjustment structure includes an adjustment base 31 that is hollow inside and fixedly connected to the fixed block at the bottom, a sliding block 33 that is inserted into the adjustment base and has gaps between its two sides and the base, a threaded post 32 that is located outside the adjustment base and inserted into the sliding block at the other end and threadedly connected to the sliding block, a rotating disk 35 that is fixedly connected to one end of the threaded post, a support plate 34 that is fixedly connected to the top of the sliding block, an adjustment assembly 36 that is connected to the support plate, two springs 38 that are fixedly connected to the adjustment assembly at one end, a limiting rod 37 that is fixedly connected to the adjustment assembly and located inside the springs, a connecting plate 39 that is connected to the other end of the springs, and a rotating roller 301 that is located between the two connecting plates and is at the same height as the outer edge of the conveyor belt.

[0025] In this embodiment, rotating the handle of the rotating component drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod causes the two fixed blocks to move in opposite directions, thereby changing the distance between the two rotating rollers. This facilitates belt alignment for different sizes and enhances the practicality of the device. Rotating the rotating disc drives the threaded column to rotate, allowing for fine-tuning of the adjustment device's position, and subsequently, fine-tuning the position of the rotating rollers to align the conveyor belt, further simplifying the device's use. Springs cushion the rotating rollers, preventing direct impact between the rollers and the belt from causing damage.

[0026] Example 2

[0027] A belt correction device for a mining conveyor belt includes a rotating mechanism 2 and two adjusting mechanisms 3.

[0028] The rotating mechanism includes a rotating box 21 fixedly connected at both ends to the belt conveyor frame of the belt conveyor via brackets, a bidirectional threaded rod 22 disposed inside the rotating box with one end rotatably connected to the inner wall of the rotating box and the other end passing through the rotating box, two symmetrically arranged fixing blocks 23 threadedly connected to the bidirectional threaded rod, a rotating rod 24 located outside the rotating box and fixedly connected to the bidirectional threaded rod, and a rotating component 1 fixedly connected to the rotating rod. The rotating component consists of a turntable and a handle. One end of the handle is fixedly connected to the outer edge of the outer surface of the turntable, and the center of the inner surface of the turntable is fixedly connected to the rotating rod.

[0029] The adjustment structure includes an adjustment base 31 that is hollow inside and fixedly connected to the fixed block at the bottom, a sliding block 33 that is inserted into the adjustment base and has gaps between the sliding block and the base on both sides, a threaded post 32 that is located outside the adjustment base and inserted into the sliding block at the other end and threadedly connected to the sliding block, a rotating disk 35 that is fixedly connected to one end of the threaded post, a support plate 34 that is fixedly connected to the top of the sliding block, an adjustment assembly 36 that is connected to the support plate, two springs 38 that are fixedly connected to the adjustment assembly at one end, a limiting rod 37 that is fixedly connected to the adjustment assembly and located inside the springs, a connecting plate 39 that is connected to the other end of the springs, and a rotating roller 301 that is located between the two connecting plates and is at the same height as the outer edge of the conveyor belt.

[0030] The adjustment assembly includes a semi-circular adjustment box 363, with several bolt through holes evenly distributed near the outer periphery of the adjustment box, a connecting column fixedly connected at one end to the semi-circular surface of the adjustment box and hinged at the other end to the support plate, a bolt 361 and a nut 362 threadedly connected to the bolt through holes, and a fixing through hole provided on the support plate threadedly connected to the bolt; the spring and the limiting rod are fixedly connected to the side wall of the adjustment box.

[0031] In this embodiment, by changing the hole on the adjusting component 363, the tilt angle of the rotating roller 301 can be changed by using the stud 361 and nut 362 to fix it to the support plate 34, which facilitates the correction of belts with different appearances and enhances the practicality of the device.

[0032] The method of using this utility model device is as follows:

[0033] 1. Fix both ends of the rotating box to the belt conveyor frame of the conveyor belt using brackets, and make the rotating roller level with the outer edge of the conveyor belt;

[0034] 2. By rotating the rotating component, the bidirectional threaded column is driven to rotate, which in turn drives the two fixed blocks to move in opposite directions, thereby driving the two rotating rollers on the adjustment structure to move, thus adjusting the distance between the rotating rollers; then by rotating the rotating disk, the distance between the rotating rollers is finely adjusted until the distance between the rotating rollers is the same as the width of the belt.

[0035] 3. Insert the stud into the hole on the adjusting component, then insert it into the fixing through hole of the support plate, and connect the nut and bolt. By inserting the stud into different holes, the tilt angle of the rotating roller with the adjusting component as the center can be changed. By screwing the nut in a certain distance, the angle between the adjusting component and the support plate can also be adjusted, thus changing the tilt angle of the rotating roller. The angle of the rotating roller can be adjusted to the optimal position to adapt to the angle of the belt.

[0036] 4. After the belt returns to its normal position, rotate the rotating component to move the fixed block in the opposite direction, causing the rotating roller to disengage from the belt. When the belt deviates again, repeat steps 2 and 3 to correct the belt alignment.
