Description

Technical Field

[0001] This utility model belongs to the field of ore mining technology, specifically relating to an ore conveyor belt correction and tension adjustment device. Background Technology

[0002] In ore mining, conveyor belts are typically used to transport ore for easier handling. The main structure of a conveyor belt consists of two drive rollers on a frame that rotate the belt to complete the transport.

[0003] However, after long-term use, the conveyor belt may loosen due to the pressure of the ore weight. A loose conveyor belt will not fit completely with the drive roller, and the conveyor belt will shift on the surface of the drive roller, causing one side of the conveyor belt to rub against the frame, affecting the conveying. Utility Model Content

[0004] This utility model discloses a device for correcting deviation and adjusting tension of an ore conveyor belt, which aims to solve the technical problem that the conveyor belt will deviate after it becomes slack.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for correcting deviation and adjusting tension of an ore conveyor belt includes a base plate, a support frame fixedly connected to the upper surface of the base plate, a conveyor belt installed above the support frame, two support plates fixedly connected to the upper surface of the base plate, a fixed roller rotatably connected to the opposite face of the two support plates, a concave base fixedly connected to the upper surface of the base plate, a threaded rod rotatably connected to the upper surface of the concave base, an L-shaped seat fixedly connected to the upper surface of the concave base, the top end of the threaded rod rotatably connected to the inner top wall of the L-shaped seat, and two threaded rods. A drive motor for driving the threaded rods to rotate is installed on the lower surface of the concave base.

[0007] The threaded rod is threadedly connected to a movable plate. A concave seat is detachably connected to the upper surface of the movable plate. The inner front and inner rear walls of the concave seat are provided with grooves. A circular groove is provided on the inner bottom wall of the groove. A sleeve is fixedly connected to the inner wall of the circular groove. A T-shaped connecting rod is slidably connected to the inner wall of the sleeve. A connecting spring is fixedly connected to the opposite face of the T-shaped connecting rod and the sleeve. A slider that overlaps with the inner wall of the groove is fixedly connected to the top of the T-shaped connecting rod. An overlapping roller is rotatably connected to the opposite face of the front and rear sliders. Mounting blocks are fixedly connected to the inner front and inner rear walls of the concave seat. A proximity switch is fixedly connected to the lower surface of the mounting block. An indicator light electrically connected to the proximity switch is fixedly connected to the front of the support frame.

[0008] By setting up a drive motor, a threaded rod, and a moving plate, the moving plate drives the concave seat to move upward, and the overlapping roller can push the conveyor belt to move upward, thereby tightening the conveyor belt and preventing the conveyor belt from shifting due to slack. When the conveyor belt is slack, the elastic force of the connecting spring will push the T-shaped connecting rod to move the overlapping roller upward and close to the proximity switch, turning on the power of the indicator light for timely reminder.

[0009] In a preferred embodiment, the output end of the drive motor is fixedly connected to the end face of one of the threaded rods, and a sprocket is fixedly connected to the surface of the threaded rod. The two sprockets are connected by a chain drive.

[0010] By setting up a sprocket, the drive motor drives one of the threaded rods to rotate. The transmission of the sprocket and chain enables the two threaded rods to rotate synchronously, which facilitates the lifting and lowering of the moving plate.

[0011] In a preferred embodiment, a connecting strip is fixedly connected to the lower surface of the concave seat, a connecting groove is formed on the upper surface of the movable plate, the surface of the connecting strip overlaps with the inner wall of the connecting groove, T-shaped grooves are formed on both the inner front and inner rear walls of the connecting groove, a T-shaped positioning block is slidably connected to the inner wall of the T-shaped groove, a return spring is fixedly connected to the opposite surface of the T-shaped positioning block and the T-shaped groove, the upper and lower surfaces of the T-shaped positioning block are both arc-shaped, positioning grooves are formed on both the front and back of the connecting strip, the surface of the T-shaped positioning block overlaps with the inner wall of the positioning groove, threaded holes communicating with the inside of the T-shaped groove are formed on both the front and back of the movable plate, a clamping bolt is threadedly connected to the inner wall of the threaded hole, the end face of the clamping bolt overlaps with the surface of the T-shaped positioning block, limit blocks are fixedly connected to both sides of the slider, a limit sliding groove is formed on the inner side wall of the groove, and the surface of the limit block overlaps with the inner wall of the limit sliding groove.

[0012] By incorporating connecting strips, clamping bolts, T-shaped positioning blocks, and return springs, the concave seat can be easily disassembled and assembled on the moving plate, facilitating the inspection and replacement of components on the concave seat.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting up a drive motor, threaded rod and moving plate, the moving plate drives the concave seat to move upward, and the overlapping roller can push the conveyor belt to move upward, thereby tightening the conveyor belt and preventing the conveyor belt from shifting due to slack. When the conveyor belt is slack, the elastic force of the connecting spring will push the T-shaped connecting rod to move the overlapping roller upward and close to the proximity switch, turning on the power of the indicator light for timely reminder.

[0015] 2. Loosen the clamping bolt, move the T-shaped positioning block away from the clamping bolt, and insert the connecting strip into the connecting groove. At this time, the arc surface of the T-shaped positioning block is compressed, and the return spring is squeezed. After the connecting strip is fully placed, the T-shaped positioning block is aligned with the positioning groove. The elastic force of the return spring pushes the T-shaped positioning block into the positioning groove, which can position the connecting strip. Then, reverse the clamping bolt to make the clamping bolt press against the T-shaped positioning block. Similarly, after loosening the clamping bolt, the connecting strip can be pulled out directly, which is convenient for the maintenance and replacement of the parts on the concave seat.

[0022] A threaded rod 7 is rotatably connected to the upper surface of the concave base 6, and an L-shaped seat 8 is fixedly connected to the upper surface of the concave base 6. The top end of the threaded rod 7 is rotatably connected to the inner top wall of the L-shaped seat 8. There are two threaded rods 7. A drive motor 9 for driving the threaded rods 7 to rotate is installed on the lower surface of the concave base 6. The output end of the drive motor 9 is fixedly connected to the end face of one of the threaded rods 7. A sprocket 20 is fixedly connected to the surface of the threaded rod 7. The two sprockets 20 are connected by chain drive.

[0023] The threaded rod 7 is threadedly connected to a movable plate 10. The upper surface of the movable plate 10 is detachably connected to a concave seat 11. The inner front wall and inner rear wall of the concave seat 11 are both provided with grooves. The inner bottom wall of the groove is provided with a circular groove. The inner wall of the circular groove is fixedly connected to a sleeve 12. The inner wall of the sleeve 12 is slidably connected to a T-shaped connecting rod 13. The opposite face of the T-shaped connecting rod 13 and the sleeve 12 is fixedly connected to a connecting spring 14. The top end of the T-shaped connecting rod 13 is fixedly connected to a slider 15 that overlaps with the inner wall of the groove.

[0024] Limiting blocks are fixedly connected to both sides of the slider 15. A limiting groove is opened on the inner side wall of the groove. The surface of the limiting block overlaps with the inner wall of the limiting groove. An overlapping roller 16 is rotatably connected to the opposite surfaces of the front and rear sliders 15. Mounting blocks 17 are fixedly connected to the inner front wall and inner rear wall of the concave seat 11. A proximity switch 18 is fixedly connected to the lower surface of the mounting block 17. An indicator light 19 electrically connected to the proximity switch 18 is fixedly connected to the front of the support frame 2.

[0025] The drive motor 9 drives the threaded rod 7 to rotate, the moving plate 10 drives the concave seat 11 to move upward, and the overlapping roller 16 can push the conveyor belt 3 to move upward, thereby tightening the conveyor belt 3 and preventing the conveyor belt 3 from becoming loose and causing deviation. When the conveyor belt 3 is loose, the elastic force of the connecting spring 14 will push the T-shaped connecting rod 13 to drive the overlapping roller 16 to move upward and approach the proximity switch 18, turn on the power of the indicator light 19, and provide timely reminder.

[0026] like Figure 3 and 4 In a preferred embodiment, a connecting strip 21 is fixedly connected to the lower surface of the concave seat 11, a connecting groove is provided on the upper surface of the movable plate 10, the surface of the connecting strip 21 overlaps with the inner wall of the connecting groove, and T-shaped grooves are provided on both the inner front wall and the inner rear wall of the connecting groove, and a T-shaped positioning block 22 is slidably connected to the inner wall of the T-shaped groove.

[0027] A return spring 24 is fixedly connected to the opposite surface of the T-shaped positioning block 22 and the T-shaped groove. The upper and lower surfaces of the T-shaped positioning block 22 are both arc-shaped. Positioning grooves are provided on the front and back sides of the connecting strip 21. The surface of the T-shaped positioning block 22 overlaps with the inner wall of the positioning groove. Threaded holes communicating with the inside of the T-shaped groove are provided on the front and back sides of the moving plate 10. A clamping bolt 23 is threadedly connected to the inner wall of the threaded hole. The end face of the clamping bolt 23 overlaps with the surface of the T-shaped positioning block 22.

[0028] Loosen the clamping bolt 23 to move the T-shaped positioning block 22 away from the clamping bolt 23, and insert the connecting strip 21 into the connecting groove. At this time, the arc surface of the T-shaped positioning block 22 is compressed and the return spring 24 is squeezed. After the connecting strip 21 is fully placed, the T-shaped positioning block 22 is aligned with the positioning groove. The elastic force of the return spring 24 pushes the T-shaped positioning block 22 into the positioning groove, which can position the connecting strip 21. Then reverse the clamping bolt 23 so that the clamping bolt 23 clamps the T-shaped positioning block 22. Similarly, after loosening the clamping bolt 23, the connecting strip 21 can be pulled out directly, which is convenient for the inspection and replacement of the components on the concave seat 11.

[0029] Working principle: Under normal use, the overlapping roller 16 pushes the conveyor belt 3 upwards to a taut state, and the reaction force of the conveyor belt 3 pushes the overlapping roller 16 downwards. At this time, the overlapping roller 16 pushes the T-shaped connecting rod 13 towards the sleeve 12 through the slider 15. The connecting spring 14 is squeezed and contracted, and the overlapping roller 16 moves away from the proximity switch 18. When the conveyor belt 3 becomes slack, the elastic force of the connecting spring 14 will push the T-shaped connecting rod 13 upwards, which in turn pushes the overlapping roller 16 upwards. The overlapping roller 16 approaches the proximity switch 18, at which time the indicator light 19 lights up to remind the user. The drive motor 9 is started, and the drive motor 9 drives the threaded rod 7 to rotate. The moving plate 10 moves, and the concave seat 11 drives the overlapping roller 16 upwards, which can tighten the conveyor belt 3. The overlapping roller 16 is forced to move downwards away from the proximity switch 18, and the indicator light 19 turns off, so that the device can tighten the conveyor belt 3 and prevent the conveyor belt 3 from shifting due to slack.
