Description

Technical Field

[0001] The present invention relates to the technical field of aramid core conveyor belt monitoring, and particularly to an aramid core conveyor belt monitoring and repairing device and method. Background Art

[0002] In recent years, aramid core conveyor belts have begun to be widely used in fields such as mines, gradually replacing traditional steel wire core conveyor belts for underground mining operations in mining areas. Compared with other traditional conveyor belts, aramid core conveyor belts have the advantages of light weight, impact resistance, corrosion resistance, and long service life, and can complete transportation work more efficiently and for a longer period of time;

[0003] Aramid core conveyor belts used in mines are used in harsh environments for a long time, which will gradually cause problems such as conveyor belt surface corrosion and conveyor belt scratches. When the conveyor belt surface is damaged to a certain extent, it will cause a belt breakage fault, resulting in a belt breakage accident. Therefore, it is necessary to conduct long-term monitoring of the aramid core conveyor belts inside the mine and always pay attention to the damage of the conveyor belt;

[0004] However, when the conveyor belt detects slight damage (faults such as slight scratches on the belt surface that do not affect the overall operation), it will not stop for repair, which will seriously reduce work efficiency; but if the belt surface is not treated, the damage area will expand later, causing irreparable losses; at the same time, when the repair personnel arrive, they cannot accurately find the damage area and cannot repair it in time, and cannot solve the safety hazard;

[0017] S1: Conveyor belt area monitoring; in this step, the electromagnetic detection device continuously detects a partial area of the conveyor belt, emits and receives electromagnetic waves, and simultaneously generates a detection area image to detect internal damage of the conveyor belt; continuously monitors a small area to prevent waste of energy caused by large-area comprehensive continuous monitoring;

[0018] S2: When an abnormal state occurs, the conveyor belt is processed. In this step, when the image exported by the electromagnetic detection device shows an abnormality, it is initially judged that it is caused by dust accumulation or debris accumulation on the conveyor belt, and an instruction is issued to make the first driving member drive the first electric push rod to extend, and the cleaning device moves downward through the top plate, and the cleaning plate contacts the conveyor belt; when the first electric push rod moves downward, the piston connecting rod is squeezed, and the first telescopic tube extends through the first communication cavity, so that the clamping block extends outward, and the clamping block clamps and fixes the conveyor belt; the connecting device moves along with the conveyor belt, driving the first elastic rod to extend, and the cleaning plate is restricted by the fixed rod, and the fixed cleaning plate brushes the surface of the moving conveyor belt to remove the debris on the belt surface, preventing abnormal display in the monitoring image due to debris accumulation or serious dust accumulation on the conveyor belt;

[0019] S3: If the abnormality still exists, start comprehensive detection of the area. In this step, when the abnormal area damage detected by the electromagnetic detection device still exists after being cleaned by the cleaning device, it is judged that the belt surface is damaged at this time, and the electromagnetic detection device starts to perform a large-area comprehensive detection on the abnormal area and the surrounding area;

[0020] S4: Determine the area and position where the damage appears. In this step, through the comprehensive detection by the electromagnetic detection device, it is judged which area of repair area one or repair area two the damage area is specifically in;

[0021] S5: Issue corresponding instructions according to the damage situation. In this step, when the electromagnetic detection device determines that damage appears in repair area one or repair area two, the damage area is repaired by the repair device:

[0022] When the damaged area is in Repair Area 1 and Repair Area 2, the two areas are detected separately, and the corresponding areas are repaired to prevent the damaged area from expanding due to subsequent work, and a warning is issued to prompt the maintenance personnel to come for repair; the repaired area facilitates the maintenance personnel to determine the damaged area.

[0023] When the damaged area exceeds the scope of Repair Area 1 and Repair Area 2, it is determined that the belt surface is damaged on a large scale. At this time, the machine is stopped and an alarm is issued to prevent subsequent safety accidents.

[0024] Advantages of the present invention:

[0025] 1. Stabilizing devices are arranged on both sides of the connecting device of the present invention. Stabilizing wheels are arranged at the upper and lower ends of the stabilizing devices. The stabilizing wheels clamp the conveyor belt, which can smooth out the fluctuations generated by the conveyor belt and prevent problems such as the conveyor belt shaking and falling off.

[0026] 2. The electromagnetic detection device of the present invention can continuously monitor some areas. When the image in the monitored area appears abnormal, the damaged area of the belt surface is cleaned by the cleaning device to prevent abnormal images caused by dust accumulation and debris accumulation on the belt.

Detailed implementation manners

[0052] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that it is easy for those with ordinary skills in the prior art in the field to which the present invention belongs to implement these embodiments; however, the present invention can also be implemented in various different forms, so the present invention is not limited to the embodiments described below; in addition, in order to more clearly describe the present invention, components not connected to the present invention will be omitted from the drawings.

[0053] First embodiment:

[0054] In this embodiment, a monitoring and repairing device for an aramid core conveyor belt is shown;

[0055] As Figure 1As shown, the conveying device 1 is located in the mine. The conveying device 1 is arranged at one end of the conveyor belt 11 for transporting coal mines. While avoiding affecting the transportation work, it continuously monitors the starting position of the conveyor belt 11. Inside the conveying device 1, the driving motor 13 drives the conveying roller 12 to rotate, thereby driving the conveyor belt 11 to perform a transportation movement.

[0056] Above the conveying device 1, there is a connecting device 2. One side of the connecting device 2 is connected to the upper inner wall of the conveying device 1 through an elastic rod 21. The elastic rod 21 itself has a certain elasticity and can be stretched. When not under external force, it is always in a contracted state.

[0057] On the other side of the connecting device 2, there is an electromagnetic detection device 3. The electromagnetic detection device 3 can emit and receive electromagnetic waves to detect the surface and inside of the conveyor belt 11. Finally, an image is obtained through image data processing (as shown in Figure 18 、 Figure 19 ).

[0058] On both sides below the connecting device 2, there are stabilizing devices 4. The stabilizing devices 4 clamp and roll the conveyor belt 11 through the stabilizing wheels 43, so that the conveyor belt 11 can run smoothly and prevent problems such as fluctuations of the conveyor belt 11 and shedding of the belt surface.

[0059] Above the connecting device 2, there is a repair device 6, which can repair a small area of the damaged area of the conveyor belt 11 to prevent the damaged position from continuously expanding later and causing more serious safety accidents.

[0060] On both sides of the repair device 6, there are driving parts 7. The driving parts 7 are fixedly arranged above the connecting device 2 and are connected to both sides of the repair device 6 through the electric push rods 71. The driving parts 7 can drive the electric push rods 71 to extend, thereby driving the repair device 6 to perform a certain degree of lifting movement.

[0061] As Figure 2 shown, the driving motor 13 is arranged on one side of the conveying device 1 and drives the conveyor belt 11 to move by driving the conveying roller 12.

[0062] As Figure 3As shown in the figure, the stabilizing device 4 is arranged on both sides of the connecting device 2 to clamp and roll the conveyor belt 11; an electric push rod 42 is arranged above the stabilizing device 4, and the electric push rod 42 is connected to a driving member 421. The driving member 421 is fixedly arranged above the connecting device 2. The driving member 421 can drive the electric push rod 42 to perform telescopic movement, so as to squeeze the upper end surface of the stabilizing device 4; a pushing plate 422 is fixedly arranged on the electric push rod 42. When the electric push rod 42 performs telescopic movement, the pushing plate 422 will follow and move up and down; the other end of the pushing plate 422 is inside the pushing groove 55 of the cleaning device 5. When the pushing plate 422 moves downward, it will drive the cleaning device 5 to move downward for a certain distance;

[0063] As Figure 4 shown in the figure, a stabilizing wheel 43 is arranged inside the groove of the stabilizing device 4 to continuously roll the conveyor belt 11; clamping blocks 48 are arranged on both sides of the stabilizing wheel 43; a piston connecting rod 44 is arranged on one side above the stabilizing device 4. The piston connecting rod 44 is below the electric push rod 42. When the electric push rod 42 extends driven by the driving member 421, it will squeeze the piston connecting rod 44 to move into the stabilizing device 4;

[0064] As Figure 5 、 Figure 6 shown in the figure, the middle part of the lower part of the piston connecting rod 44 is connected to the inside of the stabilizing device 4 through an elastic rod 442. Two groups of pistons 441 are arranged on both sides of the lower part of the piston connecting rod 44. The pistons 441 are inside the piston chamber 45. When the piston connecting rod 44 moves downward, the pistons 441 squeeze the piston chamber 45. Through the communication chamber 46, the telescopic tube 47 extends, so as to drive the clamping blocks 48 to extend outwards to clamp the conveyor belt 11, so that the stabilizing device 4 and the connecting device 2 move synchronously with the movement of the conveyor belt 11;

[0065] As Figure 7 shown in the figure, this figure is a schematic diagram of the state when the electric push rod 42 pushes the piston connecting rod 44 downward and the clamping blocks 48 extend outwards through the communication chamber 46;

[0066] As Figure 8As shown in the figure, a cleaning plate 51 is provided below the cleaning device 5, and a brush structure is provided at the bottom of the cleaning plate 51, which can scrape the surface of the conveyor belt 11 to clean the impurities and dust accumulated on the conveyor belt 11; elastic rods three 52 are provided on both sides above the cleaning device 5. The elastic rods three 52 are composed of a disc structure with a larger diameter at the upper end and an elastic structure at the lower end. The cross-section of the elastic rods three 52 is "T" shaped, and the lower ends of the elastic rods three 52 have a certain elasticity and can be stretched to a certain extent. When the elastic rods three 52 are not subject to external forces, the elastic rods three 52 are in a contracted state; one side of the cleaning device 5 is connected to the conveying device 1 through a fixing rod 53. One end of the fixing rod 53 connected to the cleaning device 5 is located in the fixing chute 54 of the cleaning device 5, and the other end of the fixing rod 53 is fixed to the conveying device 1. The fixing rod 53 can slide up and down inside the fixing chute 54 of the cleaning device 5; rectangular groove-shaped pushing grooves 55 are provided on the side surfaces at both ends of the cleaning device 5. The pushing grooves 55 can contact the pushing plate 422 on the stabilizing device 4. When the pushing plate 422 moves downward, by squeezing the lower end surface of the pushing groove 55, the cleaning device 5 is driven to move downward;

[0067] As Figure 9 , Figure 10 shown in the figure, the "T" shaped upper end disc structure of the elastic rod three 52 of the cleaning device 5 is located inside the cleaning chute 22 of the connecting device 2. When the elastic rod three 52 moves along the cleaning chute 22 to one side, the disc structure will be restricted by the cleaning chute 22 and will not protrude from the cleaning chute 22; the rear of the connecting device 2 is connected to the conveying device 1 through an elastic rod one 21;

[0068] When the driving part one 421 drives the electric push rod one 42 to extend, the pushing plate 422 squeezes the lower end surface of the pushing groove 55, causing the cleaning device 5 to move downward, and the cleaning plate 51 contacts the conveyor belt 11; as the electric push rod one 42 extends, it squeezes the piston connecting rod 44, and through the communication cavity one 46, the clamping block 48 extends out. The clamping block 48 clamps the conveyor belt 11, so that as the conveyor belt 11 moves, the stabilizing device 4 drives the connecting device 2 to move synchronously in the moving direction of the conveyor belt 11. The cleaning device 5 is restricted by the fixing rod 53 and does not follow the movement, and brushes the surface of the moving conveyor belt 11. The elastic rod three 52 of the cleaning device 5 slides inside the cleaning chute 22 and is restricted by the "T" shaped upper end surface of the cleaning chute 22 on the elastic rod three 52, and the elastic rod three 52 will not recover. The cleaning plate 51 of the cleaning device 5 always contacts the conveyor belt 11;

[0069] After the abnormal handling of the conveyor belt 11 is completed, the driving member 421 drives the electric push rod 42 to contract. The piston connecting rod 44 is restored under the action of the elastic rod 442. The clamping block 48 contracts through the communication chamber 46, separating the connecting device 2 from the conveyor belt 11. The connecting device 2 is restored under the action of the elastic rod 21. The elastic rod 52 loses the restriction of the cleaning chute 22, and the cleaning device 5 is restored under the action of the elastic rod 52.

[0070] As Figure 11 shown, the lower part of the driving member 421 is connected to the top push plate 422 through the electric push rod 42. One end of the top push plate 422 is inside the top push groove 55 of the connecting column 41 of the connecting device 2 through the stabilizing device 4.

[0071] As Figure 12 shown, the cleaning device 5 is inside the receiving groove 56 of the connecting device 2. When the cleaning device 5 drives the electric push rod 42 to extend through the driving member 421, the bottom of the top push groove 55 is squeezed by the top push plate 422 to drive the cleaning device 5 to move downward. As the connecting device 2 moves with the conveyor belt 11, the cleaning device 5 does not move under the restriction of the fixed rod 53. The elastic rod 52 of the cleaning device 5 moves toward the other side inside the cleaning chute 22, and the cleaning device 5 cannot be restored due to the lower restriction of the connecting device 2. When the connecting device 2 is restored, the cleaning device 5 will enter the receiving groove 56 under the action of the elastic rod 52.

[0072] As Figure 11 shown, lifting plates 66 are provided at both ends of the repair device 6.

[0073] As Figure 12 、 Figure 13 shown, two sets of pressing plates 61 are provided inside the repair device 6. The pressing plates 61 are connected to the driving member 612 through the electric push rods 611. The driving member 612 drives the electric push rods 611 to perform telescopic movements, thereby driving the pressing plates 61 to perform lifting movements.

[0074] Both sides of the repair device 6 are provided with storage bins 621. Repair strips 62 are stored inside the storage bins 621. The repair strips 62 are composed of a wear-resistant rubber layer and a reinforcing layer. The wear-resistant rubber layer has good wear resistance, tear resistance and aging resistance, and can withstand the friction and impact during the operation of the conveyor belt. The reinforcing layer uses high-strength fiber materials such as nylon and polyester to enhance the strength and tensile resistance of the repair strips 62. An upper cover 622 is provided above the storage bins 621, which can be opened to put into or take out the repair strips 62 inside the storage bins 621.

[0075] One side of the repair strip 62 is provided with a pushing member 63. The pushing member 63 is connected to the third driving member 632 through the third electric push rod 631. The third driving member 632 can drive the third electric push rod 631 to expand and contract, so that the pushing member 63 moves inside the storage bin 621 to push the repair strip 62.

[0076] As Figure 14 shown, the pushing member 63 is "L"-shaped. A convex-shaped clamping block 633 is arranged below the pushing member 63. When the pushing member 63 moves towards the other side of the third driving member 632, the clamping block 633 will squeeze the control rod 641 on one side of the second piston 64, compress the fourth elastic rod 642, so that the second piston 64 moves towards one side. Through the second communication cavity 643, the second telescopic tube 644 contracts, driving the baffle 65 to move towards the direction of the third driving member 632.

[0077] As Figure 15 shown, a glue injection device 651 is arranged below the baffle 65. This device is an electronic device with a module for controlling the glue injection amount and opening / closing. It coats the surface of the conveyor belt 11 through the glue injection head 652, facilitating the adhesion of the repair strip 62 to the cleaned conveyor belt 11.

[0078] As Figure 16 shown, this figure shows that the third driving member 632 drives the third electric push rod 631 to extend, and the repair strip 62 is pushed towards the pressing plate 61 through the pushing member 63, facilitating the subsequent adhesion of the repair strip 62 to the conveyor belt 11. At this time, the clamping block 633 of the pushing member 63 does not contact the control rod 641 of the second piston 64, and the baffle 65 closes the outlet to prevent the repair strip 62 from falling off along the outlet.

[0079] As Figure 17 shown, this figure is a bottom view of the repair device 6. Multiple groups of glue injection devices 651 are arranged on the baffle 65 of the repair device 6, facilitating the comprehensive coating of the surface of the conveyor belt 11 to prevent problems such as incomplete adhesion and subsequent detachment of the repair strip 62.

[0080] The basic principle of this embodiment:

[0081] When the electromagnetic detection device 3 detects an abnormal image, the first driving member 421 drives the first electric push rod 42 to extend. The first electric push rod 42 will squeeze the piston connecting rod 44, driving the first piston 441 to move downward. Through the first communication cavity 46, the first telescopic tube 47 extends, driving the clamping block 48 to extend outward. The conveyor belt 11 is clamped by the clamping block 48, so that the connecting device 2 moves along with the conveyor belt 11, stretching the first elastic rod 21.

[0082] When the electric push rod 42 extends downward, it drives the top push plate 422 to squeeze the lower end surface of the top push groove 55, driving the cleaning device 5 to move downward. The cleaning device 5 is restricted by the fixed rod 53 and does not move. As the connecting device 2 moves along with the conveyor belt 11, the cleaning device 5 brushes the surface of the conveyor belt 11 through the cleaning plate 51, preventing abnormal monitoring images caused by dust accumulation or debris accumulation on the surface of the conveyor belt 11.

[0083] When there are still abnormalities in the exported image of the cleaned conveyor belt 11, the electromagnetic detection device 3 conducts a comprehensive detection of the abnormal area to determine the damaged area and damage area of the conveyor belt 11, and the repair device 6 repairs the damaged area according to the size of the damaged area.

[0084] Embodiment 2:

[0085] In this embodiment, a judgment method and process for monitoring and repairing an aramid core conveyor belt are shown.

[0086] As Figure 18 shown, this figure is a partial area display image of the aramid core conveyor belt obtained after scanning and image processing by the electromagnetic detection device 3. The warp and weft lines of the aramid core inside the conveyor belt 11 can be clearly seen in this image.

[0087] As Figure 19 shown, this figure is an image of the damaged aramid core conveyor belt 11 under the scanning of the electromagnetic detection device 3. The left longitudinal black area and the right circular black area in the image are the damaged areas.

[0088] As Figure 20 shown, this figure is a schematic diagram of the area comprehensively scanned by the electromagnetic detection device 3 for the conveyor belt 11. The upper part is marked as repair area one 8, which is below one set of pressing plates 61 of the repair device 6; the lower part is marked as repair area two 9, which is below the other set of pressing plates 61 of the repair device 6; the circular mark in the figure is a schematic diagram of the position of the damaged area in the image. The damaged area one 91 is in the repair area one 8, the damaged area two 92 is inside the repair area one 8 and the repair area two 9, and the damaged area three 93 is in the repair area two 9.

[0089] As Figure 21 shown, combined with Figure 1 the application scenario of the conveyor belt 11 shown, this embodiment two provides a monitoring method for monitoring and repairing the conveyor belt. The method includes:

[0090] S101, conveyor belt area monitoring;

[0091] In this step, the electromagnetic detection device 3 continuously detects a partial area of the conveyor belt 11, emits and receives electromagnetic waves, and simultaneously generates an image of the detection area (as Figure 13 shown) to detect internal damage of the conveyor belt 11; continuously monitors a small area to prevent waste of energy caused by large-area and comprehensive continuous monitoring;

[0092] S102. When an abnormal state occurs, process the conveyor belt;

[0093] In this step, when the image exported by the electromagnetic detection device 3 is abnormal (as Figure 19 shown), it is preliminarily judged that it is caused by dust or debris accumulation on the conveyor belt 11. A command is issued to make the driving member 421 drive the electric push rod 42 to extend, and the cleaning device 5 moves downward through the top plate 422, and the cleaning plate 51 contacts the conveyor belt 11; when the electric push rod 42 moves downward, the piston connecting rod 44 is squeezed, and the telescopic tube 47 extends through the first communication cavity 46, so that the clamping block 48 extends outward, and the clamping block 48 clamps and fixes the conveyor belt 11; the connecting device 2 moves along with the conveyor belt 11, driving the first elastic rod 21 to extend. The cleaning plate 51 is restricted by the fixing rod 53, and the fixed cleaning plate 51 brushes the surface of the moving conveyor belt 11 to remove the debris on the belt surface, preventing abnormal display in the monitoring image due to debris accumulation or serious dust accumulation on the conveyor belt 11;

[0094] S103. If the abnormality still exists, start comprehensive detection of the area;

[0095] As Figure 20 shown, in this step, when the abnormal area damage detected by the electromagnetic detection device 3 still exists after being cleaned by the cleaning device 5, it is determined that the belt surface is damaged at this time, and the electromagnetic detection device 3 starts comprehensive detection of the abnormal area and the surrounding area;

[0096] S104. Determine the area and location where the damage appears;

[0097] As Figure 22 shown, in this step, through the comprehensive detection by the electromagnetic detection device 3, it is judged which area of the first repair area 8 or the second repair area 9 the damage area is specifically in;

[0098] S105. Issue corresponding commands according to the damage situation;

[0099] In this step, when the electromagnetic detection device 3 determines that damage has occurred in the first repair area 8 or the second repair area 9, the repair device 6 repairs the damaged area:

[0100] If the damaged area is in repair area 1 8 and repair area 2 9, detect the two areas separately, repair the corresponding areas, prevent the damaged area from expanding due to subsequent work, and issue a warning to prompt the maintenance personnel to come for repair; the repaired area facilitates the maintenance personnel to determine the damaged area;

[0101] If the damaged area exceeds the scope of repair area 1 8 and repair area 2 9, it is judged as large-area damage to the belt surface. At this time, stop the machine and issue an alarm to prevent subsequent safety accidents.
