[0002] Circular tube belt conveyors are widely used in mining, ports, electricity, metallurgy and other fields. Circular tube belt conveyors are usually erected at high altitudes, and during operation, they need to be inspected for rollers, belts and other equipment used to confirm the type of fault. According to a Chinese patent application with publication number CN114313884B, a conveyor belt intelligent inspection robot is disclosed. The robot can adapt to different types of rails, has a safe working environment and a high degree of automation. However, the conveyor belt intelligent inspection robot does not have the technical effect of braking the conveyor after a fault in the conveyor power system. In certain cases where there is a height difference between the upper and lower conveying heights, the material on the conveyor belt is easily reversed under the action of gravity, thereby sending the material back to the conveyor feeding end, causing the material to accumulate at the conveyor feeding end.

[0054] Compared with the prior art, the present invention has the following beneficial effects:

[0055] 1. In the present invention, air is pumped by operating a high-pressure pump, and air is pumped into the interior of each air channel under the connection of a hose. The high-pressure gas pumped into the air channel then enters the interior of the cylinder chamber, pushing the piston head downward, and driving the push rod together with the clamping claw to move downward along the inner wall of the guide groove. The downward movement of the clamping claw drives the upper brake pad to move downward together, forming an upper and lower clamping effect on the edge of the conveyor belt with the lower brake pad. After the conveyor power system fails, the conveyor belt is braked to suppress the conveyor belt from reversing, thereby preventing materials from accumulating at the feeding end of the pipe belt conveyor.

[0056] 2. In the present invention, by sliding the L-shaped brake frame back and forth along the inside of the aluminum channel plate, the lower brake pad and the upper brake pad are adjusted together, so as to be used for pipe belt conveyors of different widths, thereby improving the adaptability of the inspection equipment.

[0057] 3. In the present invention, the upper brake pad moves downward and the connecting action of the push-pull vertical rod drives the loose nut together with the spring to move downward, and then the push-pull horizontal bar is pressed down to move downward together with the trapezoidal slider. The downward movement of the trapezoidal slider drives the pick plate to move together, and further the connecting action of the connecting rod drives the brake shoe together with the friction pad to move downward, so that the bottom of the friction pad is attached to the bottom wall of the I-shaped guide rail, and the inspection equipment is braked on the surface of the I-shaped guide rail, preventing the conveyor belt from flipping and driving the inspection device to slide along the I-shaped guide rail, thereby enhancing the braking effect on the conveyor belt.

[0058] 4. In the present invention, when the inspection equipment moves linearly along the I-shaped guide rail, the rubber airbag on the edge of the guide wheel in the cleaning unit is inflated and abuts against the side wall of the I-shaped guide rail. Therefore, under the action of the rolling friction between the outer wall of the rubber airbag of the guide wheel and the side wall of the I-shaped guide rail, the guide wheel rolls along the side wall of the I-shaped guide rail, and drives the cleaning vertical axis together with the brush head to rotate. The rotation of the brush head cleans the attachments on the bottom wall of the I-shaped guide rail. On the one hand, it can ensure that the inspection equipment can move smoothly along the I-shaped guide rail. On the other hand, it can also ensure that the bottom wall of the I-shaped guide rail and the bottom of the brake shoe are in full contact at all times, thereby ensuring sufficient friction for braking.

The No. 2 brake unit 300 is used for braking the inspection device. The detector 600 is fixedly installed at the bottom of the loading plate 100. The detector 600 is used for inspecting the operating status of the circular tube belt conveyor. The driving unit 500 drives the inspection equipment to move along the I-shaped guide rail, driving the detector 600 to move together, and inspects the circular tube belt conveyor through the detector 600. At the same time, the cleaning unit 400 cleans the bottom wall of the I-shaped guide rail. If the power system of the circular tube belt conveyor fails, the detector 600 detects that the circular tube belt conveyor belt is reversed, and the No. 1 brake unit 200 clamps the edge of the circular tube belt conveyor belt to brake the circular tube belt conveyor belt and suppress the reverse of the circular tube belt conveyor belt. At the same time, the No. 2 brake unit 300 brakes the inspection equipment as a whole to the outside of the I-shaped guide rail to prevent the inspection equipment from moving and better brake the circular tube belt conveyor belt.

[0077] For further details, please refer to Figures 7 to 9 As shown:

[0078] The No. 1 brake unit 200 includes an aluminum groove plate 201, an L-shaped brake frame 202, a lower brake pad 203, a guide groove 204, a clamping claw 205, an upper brake pad 206, a cylinder chamber 207, a cylinder chamber 207, a push rod 208, a piston head 209, an air passage 2010, a tooth hole 2011, a fastening bolt 2012, a hand wheel 2013 and a high-pressure pump 2014. The aluminum groove plate 201 is fixedly mounted at the top four corners of the loading plate 100, the L-shaped brake frame 202 is slidably mounted inside the aluminum groove plate 201 and extends to the front and rear ends of the loading plate 100, the lower brake pad 203 is fixedly mounted at the bottom of the L-shaped brake frame 202, the guide groove 204 is opened at the lower part of one side of the L-shaped brake frame 202 close to the loading plate 100, the clamping claw 205 is slidably mounted inside the guide groove 204, and the upper brake pad 206 is fixed It is fixedly installed at the bottom of the clamping jaw 205 and is located directly above the lower brake pad 203. The cylinder chamber 207 is opened at the top of the guide groove 204 and is connected to the guide groove 204. The push rod 208 is fixedly installed on the top of the clamping jaw 205. The center of the push rod 208 is concentric with the center of the cylinder chamber 207. The piston head 209 is fixedly installed on the upper part of the outer wall of the push rod 208. The outer wall of the piston head 209 is slidably connected to the inner wall of the cylinder chamber 207. The airway 2010 is opened at the top of the cylinder chamber 207 and passes through the inner wall of the L-shaped brake frame 202 and extends to the end of the L-shaped brake frame 202 away from the lower brake pad 203. The airway 2010 is connected to the inside of the cylinder chamber 207. The high-pressure pump 2014 is fixedly installed on the top of the loading plate 100, and the output end of the high-pressure pump 2014 is connected to the end of the airway 2010 by a hose.

[0079] Specifically, the driving unit 500 drives the inspection device to move along the I-shaped guide rail, driving the detector 600 to move together, and the round tube belt conveyor is inspected by the detector 600. During the inspection process, if the power system of the tube belt conveyor fails, due to the left and right conveying height difference of the tube belt conveyor, the material on the conveyor belt of the tube belt conveyor is subjected to the action of gravity, and a component force is generated that is obliquely downward along the conveying direction of the conveyor belt, causing the conveyor belt to rotate in the opposite direction, and the material is sent back. After the set detector 600 detects that the material is sent back, the driving unit 500 stops driving, and the inspection device stops at the working position. shaped guide rail, and sends a start command to the high-pressure pump 2014. The high-pressure pump 2014 operates to pump air, and pumps air into the interior of each air channel 2010 under the connection of the hose. The high-pressure gas pumped into the air channel 2010 then enters the interior of the cylinder chamber 207, pushing the piston head 209 downward, and driving the push rod 208 and the clamping claw 205 to move downward along the inner wall of the guide groove 204. The downward movement of the clamping claw 205 drives the upper brake pad 206 to move downward together, forming an upper and lower clamping effect on the edge of the conveyor belt with the lower brake pad 203, braking the conveyor belt, suppressing the conveyor belt from reversing, and preventing materials from accumulating at the feeding end of the pipe belt conveyor.

[0080] For further details, please refer to Figure 7 As shown:

[0081] The thread hole 2011 is opened on the side of the aluminum channel plate 201 and passes through the side wall of the aluminum channel plate 201. The fastening bolt 2012 is screwed into the inside of the thread hole 2011. The end of the fastening bolt 2012 is abutted against the side of the L-shaped brake frame 202. The handwheel 2013 is fixedly installed on the end of the fastening bolt 2012 away from the L-shaped brake frame 202.

[0082] Specifically, if the width of the conveyor belt does not match the distance between the front and rear lower brake pads 203, the fastening bolt 2012 can be rotated by applying force to the surface of the handwheel 2013, and the L-shaped brake frame 202 can be slid back and forth along the inside of the aluminum groove plate 201, driving the lower brake pad 203 and the upper brake pad 206 to adjust to a position suitable for the width of the conveyor belt. After adjustment, the fastening bolt 2012 can be tightened to prevent the L-shaped brake frame 202 from moving again.

[0083] For further details, please refer to Figure 4 、 Figure 7 、 Figure 8 、 Figure 10 as well as Figure 11 As shown:

[0084] The second brake unit 300 includes a push-pull vertical rod 301, a push-pull horizontal bar 302, a trapezoidal slider 303, a lifting plate 304, a trapezoidal slide 305, a connecting rod 306, a brake shoe 307, a friction plate 308, a loose nut 309 and a spring 3010.

At the rear end, the specifications and position of the trapezoidal slide 305 correspond to the specifications and position of the trapezoidal slider 303, and the trapezoidal slider 303 is slidably installed inside the trapezoidal slide 305 at the corresponding position, and the connecting rod 306 is fixedly installed on the top of the pick plate 304 in the front and rear distribution, and movably passes through the loading plate 100 and extends to the periphery of its top, the brake shoe 307 is fixedly installed on the top of the connecting rod 306, the friction plate 308 is fixedly installed on the bottom of the brake shoe 307, the lock nut 309 is threadedly screwed on the upper part of the outer wall of the push-pull vertical rod 301, and the spring 3010 is sleeved on the periphery of the push-pull vertical rod 301, and the spring 3010 is fixedly installed between the top of the push-pull horizontal bar 302 and the bottom of the lock nut 309.

[0085] Specifically, the downward movement of the upper brake pad 206 also drives the loose nut 309 and the spring 3010 to move downward through the connecting action of the push-pull vertical rod 301, and then presses down the push-pull horizontal bar 302 and moves downward together with the trapezoidal slider 303. The downward movement of the trapezoidal slider 303 drives the pick plate 304 to move together, and further drives the brake shoe 307 and the friction plate 308 to move downward through the connecting action of the connecting rod 306, so that the bottom of the friction plate 308 fits against the bottom wall of the I-shaped guide rail, and brakes the inspection equipment on the surface of the I-shaped guide rail, preventing the conveyor belt from flipping and driving the inspection device to slide along the I-shaped guide rail, thereby strengthening the braking effect on the conveyor belt.

[0086] For further details, please refer to Figure 12 、 Figure 13 As shown:

[0087] The cleaning unit 400 includes a bearing frame 401, a cleaning vertical shaft 402, a brush head 403 and a guide wheel 404.

The guide wheel 404 is fixedly installed on the upper outer wall of the cleaning vertical shaft 402. A rubber airbag is provided on the edge of the guide wheel 404.

[0088] Specifically, when the inspection equipment moves linearly along the I-shaped guide rail, the rubber airbag on the edge of the guide wheel 404 in the cleaning unit 400 is inflated and abuts against the side wall of the I-shaped guide rail. Therefore, under the action of the rolling friction between the outer wall of the rubber airbag of the guide wheel 404 and the side wall of the I-shaped guide rail, the guide wheel 404 rolls along the side wall of the I-shaped guide rail, and drives the cleaning vertical shaft 402 together with the brush head 403 to rotate. The rotation of the brush head 403 cleans the attachments on the bottom wall of the I-shaped guide rail. On the one hand, it can ensure that the inspection equipment can move smoothly along the I-shaped guide rail. On the other hand, it also ensures that the bottom wall of the I-shaped guide rail and the bottom of the brake shoe 307 are in full contact at all times, thereby ensuring sufficient friction for braking.

[0089] For further details, please refer to Figure 5 As shown:

[0090] The driving unit 500 includes a vertical plate 501, a roller 502, a roller 503, a driven synchronous wheel 504, a positioning shaft 505, an idler wheel 506, a motor flange bracket 507, a servo motor 508, an active synchronous wheel 509 and a synchronous belt 5010. The vertical plate 501 is fixedly mounted on the top of the loading plate 100 symmetrically in front and back. The roller 502 is rotatably mounted on the left and right ends of the interior of the vertical plate 501 through bearings. The roller 502 has two layers, the upper and lower layers. The roller 503 is fixedly mounted on the outer wall of the roller 502 and is located between the front and rear vertical plates 501. The outer wall of the roller 503 is fixedly sleeved with a patterned rubber outer ring, and the bottom height of the roller 503 on the upper layer is the same as the bottom height of the brush head 403. The height of the driven synchronous wheel 504 corresponds to that of the upper part. The positioning shaft 505 is fixedly mounted on the side of one of the vertical plates 501 and on the same side as the driven synchronous wheel 504. The idler wheel 506 is rotatably mounted on the outer wall of the positioning shaft 505. The motor flange bracket 507 is fixedly mounted on the side of one of the vertical plates 501 and on the same side as the idler wheel 506. The servo motor 508 is fixedly mounted on the surface of the motor flange bracket 507. The driving synchronous wheel 509 is fixedly mounted on the output shaft of the servo motor 508. The synchronous belt 5010 is sleeved on the periphery of the driving synchronous wheel 509, the two idler wheels 506 and the two driven synchronous wheels 504.

[0091] Specifically, (as shown in the attached instructions Figure 1 The I-shaped track (as shown) is suspended and fixedly installed on the top of the conveyor, so that the upper and lower layers of rollers 503 are respectively stuck on the bottom and bottom wall of the I-shaped track, thereby installing the inspection device on the I-shaped track, and the output shaft of the servo motor 508 drives the active synchronous wheel 509 to rotate, and further drives the two driven synchronous wheels 504 connected thereto to rotate under the connection action of the synchronous belt 5010. The rotation of the two driven synchronous wheels 504 further drives the two rollers 502 associated therewith to rotate together with the rollers 503, thereby driving the inspection device to move in a straight line along the I-shaped track, and then drives the detector 600 located at the bottom of the loading plate 100 to move together, and inspect along the top of the pipe belt conveyor.

[0092] This solution is an intelligent inspection device for detecting the operating status of a circular belt conveyor. When working, first (as shown in the attached manual) Figure 1The I-shaped track (shown) is suspended and fixedly installed on the top of the conveyor, so that the upper and lower rollers 503 are respectively stuck on the bottom and bottom wall of the I-shaped track, thereby installing the inspection device on the I-shaped track. Thereafter, by adjusting the height of the I-shaped track, the inspection device is driven to adjust its height so that the edge of the conveyor belt is between the top of the lower brake pad 203 and the bottom wall of the upper brake pad 206. It should be noted here that if the width of the conveyor belt does not match the distance between the front and rear lower brake pads 203, the fastening bolts 2012 can be loosened and the L-shaped brake frame 202 can be slid back and forth along the inside of the aluminum channel plate 201 to drive the lower brake pad 203 and the upper brake pad 206 to be adjusted to a position suitable for the width of the conveyor belt. After adjustment, the fastening bolts 2012 are tightened to prevent the L-shaped brake frame 202 from moving again.

[0093] During the inspection process, the output shaft of the servo motor 508 drives the active synchronous wheel 509 to rotate, and further drives the two driven synchronous wheels 504 connected thereto to rotate under the connection action of the synchronous belt 5010. The rotation of the two driven synchronous wheels 504 further drives the two rollers 502 associated therewith to rotate together with the roller 503, thereby driving the inspection equipment to move linearly along the I-shaped track, and then drives the detector 600 located at the bottom of the loading plate 100 to move together, and inspect along the top of the pipe belt conveyor. During the inspection process, if the power system of the pipe belt conveyor fails, due to the left and right conveying height difference of the pipe belt conveyor, the material on the conveyor belt of the pipe belt conveyor is subjected to the action of gravity, generating a component force obliquely downward along the conveying direction of the conveyor belt, causing the conveyor belt to move. The material is reversed and sent back. After the detector 600 detects that the material is being sent back, the servo motor 508 is immediately turned off, so that the inspection device stops on the I-shaped guide rail, and a start command is sent to the high-pressure pump 2014. The high-pressure pump 2014 operates to pump air and pumps air into the interior of each air channel 2010 under the connection of the hose. The high-pressure gas pumped into the air channel 2010 then enters the interior of the cylinder chamber 207, pushing the piston head 209 downward, and driving the push rod 208 and the clamping jaws 205 to move downward along the inner wall of the guide groove 204. The downward movement of the clamping jaws 205 drives the upper brake pad 206 to move downward together, forming an upper and lower clamping effect on the edge of the conveyor belt with the lower brake pad 203, braking the conveyor belt, suppressing the conveyor belt from reversing, and preventing the material from accumulating at the feeding end of the pipe belt conveyor.

[0094] At the same time, the downward movement of the upper brake pad 206 also drives the loose nut 309 and the spring 3010 to move downward through the connection effect of the push-pull vertical rod 301, and then presses the push-pull horizontal bar 302 and the trapezoidal slider 303 downward. The downward movement of the trapezoidal slider 303 drives the lifting plate 304 to move together, and further drives the brake shoe 307 and the friction plate 308 downward through the connection effect of the connecting rod 306, so that the bottom of the friction plate 308 is attached to the bottom wall of the I-shaped guide rail, braking the inspection device on the surface of the I-shaped guide rail, preventing the conveyor belt from turning over and driving the inspection device to slide along the I-shaped guide rail, thereby strengthening the braking effect on the conveyor belt;

[0095] During the straight movement of the inspection equipment along the I-shaped guide rail, the guide wheel 404 in the cleaning unit 400 is also in contact with the side wall of the I-shaped guide rail. Therefore, under the action of the rolling friction between the outer wall of the guide wheel 404 and the side wall of the I-shaped guide rail, the guide wheel 404 rolls along the side wall of the I-shaped guide rail, and drives the cleaning vertical shaft 402 together with the brush head 403 to rotate. The attachments on the bottom wall of the I-shaped guide rail are cleaned by the rotation of the brush head 403. On the one hand, it can ensure that the inspection equipment can move smoothly along the I-shaped guide rail. On the other hand, it also ensures that there is sufficient contact between the bottom wall of the I-shaped guide rail and the bottom of the brake shoe 307 at all times, thereby ensuring sufficient friction for braking.

[0096] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principles and spirit of the invention.
