Description

[0002] Belt conveyors are continuous conveying equipment widely used in industries such as mining, metallurgy, chemicals, building materials, electricity, and grain. They use a belt as both a load-bearing and traction element to transport materials from one location to another. A belt conveyor's drive mechanism rotates a drive roller, which in turn drives the belt through friction. Material enters the belt at the inlet and is conveyed to the outlet as the belt moves. Idlers support the belt and material, reducing operational resistance. A tensioner maintains proper belt tension to prevent slippage and deviation.

[0003] The existing conveyor belt tear detection device uses a vibration sensor to detect the tear position of the belt, and detects the tear through the different vibrations generated by the contact between the torn part of the belt and the roller during movement.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] See also Figures 1 to 6The present invention provides a technical solution: a belt tear detection device, comprising a frame 1, a mounting frame 2 is provided on one side of the outer wall of the frame 1, a chassis 3 and a bracket 5 are arranged in parallel at the top of the mounting frame 2, a conveying component is provided in the inner cavity of the chassis 3, a shell 4 is provided on the top of the chassis 3, a feed port 11 is provided between the shell 4 and the chassis 3, a discharge port 12 is provided on the left side of the bottom end of the chassis 3, and the discharge port 12 is located above the belt 10, a specific gravity adjustment component is provided in the inner cavity of the shell 4, a sliding component is provided in the inner cavity of the bracket 5, two inclined adjustment plates 6 are provided at the bottom end of the sliding component, and the adjustment plate 6 is located above the belt 10, a fixed frame 7 is provided on the top of the frame 1, and a roller 8 is rotatably connected to the top of the inner cavity of the fixed frame 7, a vibration sensor 9 is provided at the bottom of the inner cavity of the fixed frame 7, and a belt 10 is supported above the roller 8. The present invention provides a specific gravity adjustment component so that the material falling onto the belt 10 is uniform in size and low in specific gravity, thereby improving the uniformity of material distribution on the belt 10 and avoiding the uneven distribution of force on the belt 10 due to the different sizes of the materials, which leads to irregular vibration. Large pieces of material can also be crushed by the rotating rod 21 to drive the crushing rod 22 to rotate. At the same time, the inclined adjustment plate 6 is used to converge the materials scattered on the belt 10 between the two adjustment plates 6 in the middle of the belt 10, thereby avoiding the uneven distribution of materials on the belt 10, which causes uneven force on the belt 10 and irregular vibration. This solves the problem that the vibration sensor 9 is affected by the uniformity of the material on the belt 10 when detecting the tear of the belt 10, resulting in a high misjudgment rate. By setting the vibration sensor 9, the vibration of the belt 10 during the process of passing the roller 8 can be detected, and the tear of the belt 10 can be detected by analyzing the difference in vibration data.

[0023] In this embodiment, the conveying assembly includes a rotating column 13 and a spiral auger 14. The right end of the rotating column 13 is rotatably connected to the right wall of the inner cavity of the chassis 3, and the spiral auger 14 is fixedly connected to the surface of the rotating column 13. The left end of the spiral auger 14 is rotatably connected to the left wall of the inner cavity of the chassis 3. The outer wall circumference of the spiral auger 14 is adapted to the inner wall circumference of the chassis 3. The motor 15 can drive the rotating column 13 to drive the spiral auger 14 to rotate and convey the material through the transmission action of the two second pulleys 24. While conveying the material, the spiral auger 14 can also stir and mix the material to a certain extent, thereby improving the uniformity of the material and reducing the specific gravity. The material conveying efficiency is sustainable and the material is evenly distributed on the belt 10.

[0024] The two sliders 27 are screwed on the screw rod 25 from the left and right sides respectively. The limiting assembly is arranged on the front wall of the inner cavity of the bracket 5 and is fixedly connected to the two sliders 27. The bottom ends of the two sliders 27 are provided with connecting rods 30. The bottom ends of the two connecting rods 30 are fixedly connected to the top ends of the two adjusting plates 6 respectively. Rotating the knob 26 drives the screw rod 25 to rotate, thereby causing the opposite threads on the left and right sides of the outer wall of the screw rod 25 to generate relative thread rotation force, so that the two sliders 27 slide relative to each other at the same time under the limiting action of the limiting groove 28 and the limiting block 29, thereby causing the two connecting rods 30 to drive the two adjusting plates 6 to slide relative to each other at the same time, thereby realizing the distance adjustment between the two adjusting plates 6.

[0025] In this embodiment, the threads on the left and right sides of the outer wall of the screw rod 25 are arranged relative to each other, so that when the screw rod 25 rotates, the threads on the left and right sides of its outer wall generate relative thread rotation force, causing the two sliders 27 to slide relative to each other at the same time under the limiting action of the limiting groove 28 and the limiting block 29.

[0026] In this embodiment, the limit assembly includes a limit groove 28 and a limit block 29. The limit groove 28 is opened on the front wall of the inner cavity of the bracket 5. The two limit blocks 29 can be slidably embedded in the limit groove 28 and are fixedly connected to the two sliders 27 respectively. The cross-sectional shape of the limit groove 28 and the limit block 29 are adapted to each other and are both in a "T" shape. Under the joint action of the limit groove 28 and the limit block 29, the slider 27 can be prevented from rotating with the screw rod 25 when the screw rod 25 rotates, thereby improving the stability of the sliding assembly during use. The inner cavity of the limit groove 28 and the outer wall of the limit block 29 are adapted to each other and are both in a "T" shape, so that one end of the limit block 29 can always remain embedded in the inner cavity of the limit groove 28, thereby improving the stability of the limit assembly during use.

[0027] In this embodiment, the specific gravity adjustment assembly includes a rotating rod 21, a breaking rod 22, a first pulley 23, a motor 15, a rotating shaft 16, a flip rod 17, a pulley 18, a lifting plate 19, and a filter hole 20. The two ends of the rotating rod 21 are respectively rotatably connected to the inner wall of the casing 4, and a plurality of breaking rods 22 are fixedly sleeved and distributed on the outer wall of the rotating rod 21. The two first pulleys 23 are respectively fixedly sleeved on the rotating rod 21 and the output end of the motor 15 and are rotatably connected through a transmission belt. The rotating shaft 16 is located below the rotating rod 21, one end of the rotating shaft 16 is fixedly connected to the output end of the motor 15, and the other end of the rotating shaft 16 is rotatably connected to the inner wall of the casing 4, the flip rod 17 is fixedly sleeved on the outer wall of the rotating shaft 16, and the pulley 18 is rotatably connected to the flip rod 1 At both ends of 7, the lifting plate 19 can be freely lifted and lowered above the rotating shaft 16 and the flip rod 17. A plurality of filter holes 20 are all opened on the lifting plate 19. The motor 15 is started, so that the motor 15 drives the rotating shaft 16 to rotate, and then the flip rod 17 drives the pulley 18 to flip, so that the lifting plate 19 vibrates up and down along a straight line under the limiting action of the telescopic component, thereby realizing the screening of the material, so that large pieces of material remain on the lifting plate 19, and the material entering the chassis 3 is relatively uniform in size and low in specific gravity, which can reduce the vibration data difference caused by the uneven force on the belt 10 due to the uneven size of the material. At the same time, the motor 15 drives the rotating rod 21 and the crushing rod 22 to rotate through the first pulley 23 to crush the large pieces of material.

[0028] In this embodiment, the specific gravity adjustment assembly also includes a telescopic assembly, which includes a telescopic cylinder 31, a telescopic rod 32, a connecting groove 33 and a connecting block 34. The telescopic cylinder 31 is arranged on the inner wall of the casing 4, and the telescopic rod 32 is slidably inserted into the telescopic cylinder 31 and its end is fixedly connected to the bottom of the lifting plate 19. The connecting groove 33 is opened on the inner wall of the telescopic cylinder 31, and the connecting block 34 is slidably embedded in the connecting groove 33 and fixedly connected to the outer wall of the telescopic rod 32. The cross-sectional shapes of the connecting groove 33 and the connecting block 34 are adapted to each other and are both dovetail-shaped. Under the joint action of the telescopic rod 32 and the telescopic cylinder 31, the lifting plate 19 can always slide up and down along a straight line, thereby improving the stability of the specific gravity adjustment assembly during use. Under the joint action of the connecting block 34 and the connecting groove 33, one end of the telescopic rod 32 can always remain inserted into the inner cavity of the telescopic cylinder 31.

[0029] In this embodiment, the end of the rotating column 13 and the output end of the motor 15 are fixedly sleeved with a second pulley 24, and the two second pulleys 24 are rotatably connected by a transmission belt, so that the motor 15 can drive the rotating column 13 to rotate synchronously during operation.

[0030] A working process of a belt tear detection device includes the following steps:

[0031] S1. Start the motor 15. The motor 15, the first pulley 23, and the second pulley 24 respectively drive the rotating shaft 16, the rotating rod 21, and the rotating column 13 to rotate, causing the flip rod 17 to push the lifting plate 19 to vibrate up and down. The material on the lifting plate 19 passes through the filter hole 20 and falls into the bottom end of the inner cavity of the housing 4. Then, it enters the inner cavity of the chassis 3 and is uniformly conveyed by the spiral auger 14, and finally falls onto the belt 10 from the discharge port 12. In addition, the large pieces of material remaining on the lifting plate 19 can be broken by the rotating rod 21 driving the crushing rod 22 to rotate and crush them, avoiding the uneven distribution of force on the belt 10 due to the different sizes of the materials, which would cause irregular vibration.

[0032] S2. According to actual needs, turn the knob 26 to adjust the distance between the two adjustment plates 6. Under the action of the inclined adjustment plates 6, the materials scattered on the belt 10 can be converged between the two adjustment plates 6 in the middle of the top of the belt 10, avoiding uneven distribution of materials on the belt 10, causing uneven force on the belt 10, and resulting in irregular vibration.

[0033] S3. The vibration frequency of the belt 10 during its movement is detected by the vibration sensor 9, and whether the belt 10 is torn is determined by the abnormal frequency.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
