Description

Technical Field

[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. 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 with application publication number CN114313884B, a conveyor belt intelligent inspection robot is disclosed, which can adapt to different types of rails, has a safe working environment and a high degree of automation. After the conveyor power system fails, the conveyor belt intelligent inspection robot does not have the technical effect of braking the conveyor. In some cases where there is a height difference between the upper and lower conveying heights, the material on the conveyor belt is easy to reverse the conveyor belt under the action of gravity, thereby sending the material back to the feeding end of the conveyor, causing the material to accumulate at the feeding end of the conveyor.

[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 each air passage through the connection of a hose. The high-pressure gas pumped into the air passage then enters 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 a failure of the conveyor power system, the conveyor belt is braked to suppress the conveyor belt from reversing, and prevent 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 forward and backward along the inside of the aluminum groove 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 tension nut and the spring to move downward, and then the push-pull horizontal bar and the trapezoidal slider are pressed downward to move downward. The downward movement of the trapezoidal slider drives the cantilever plate to move together, and further the connecting action of the connecting rod drives the brake shoe and 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, so as to prevent the conveyor belt from turning over 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 attachments on the bottom wall of the I-shaped guide rail are cleaned by the rotation of the brush head. 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 are in full contact at all times, thereby ensuring sufficient friction for braking.

The second brake unit 300 is used for braking the inspection device. The detector 600 is fixedly installed on the bottom of the loading plate 100. The detector 600 is used for inspection of the running status of the circular tube belt conveyor. 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 circular tube belt conveyor is inspected by 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 conveyor belt of the circular tube belt conveyor is reversed, and the edge of the conveyor belt of the circular tube belt conveyor is clamped by the No. 1 brake unit 200 to brake the conveyor belt of the circular tube belt conveyor to prevent the conveyor belt of the circular tube belt conveyor from reversing. At the same time, the inspection device is braked as a whole on the outside of the I-shaped guide rail by the No. 2 brake unit 300 to prevent the inspection device from moving and better brake the conveyor belt of the circular tube belt conveyor.

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

[0078] Brake unit No. 1 200 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 airway 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 a 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 fixedly mounted at the bottom of the L-shaped brake frame 202. It is fixedly installed at the bottom of the clamp 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 clamp 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 through 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 affected by gravity, and a component force is generated 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, so that the inspection device stops in the working state. 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, inhibiting 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 groove plate 201 and passes through the side wall of the aluminum groove plate 201. The fastening bolt 2012 is threadedly screwed into the inside of the thread hole 2011. The end of the fastening bolt 2012 abuts against the side of the L-shaped brake frame 202. The handwheel 2013 is fixedly installed at one 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 , Fig.10 as well as Fig.11 As shown:

[0085] Specifically, the downward movement of the upper brake pad 206 also drives the locking 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 lifting 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.

The guide wheel 404 is fixedly installed on the upper outer wall of the cleaning vertical shaft 402, and 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 axis 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 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.

[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 installed on the top of the loading plate 100 symmetrically front and back, and the roller 502 is rotatably installed on the left and right ends of the inner side of the vertical plate 501 through bearings. The roller 502 has two layers, the upper and lower layers, and the roller 503 is fixedly installed 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, wherein the bottom height of the roller 503 located on the upper layer is the same as the bottom height of the brush head 403. The driven synchronous wheel 504 is fixedly mounted on one end of the outer wall of two rollers 502 located on the upper layer, 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, and 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 manual) 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, so that the inspection device is installed on the I-shaped track, and the output shaft of the servo motor 508 drives the active synchronous wheel 509 to rotate, and further under the connection action of the synchronous belt 5010, drives the two driven synchronous wheels 504 connected thereto to rotate, and 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 equipment 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 scheme is an intelligent inspection device for detecting the running status of a round tube belt conveyor. When working, first (as shown in the attached manual) Figure 1The 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, so that the inspection device is installed on the I-shaped track, and then the height of the I-shaped track is adjusted to drive the inspection device 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 L-shaped brake frame 202 can be slid forward and backward along the inside of the aluminum groove plate 201 by loosening the fastening bolts 2012, and the lower brake pad 203 and the upper brake pad 206 can be driven to adjust 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, under the connection of the synchronous belt 5010, drives the two driven synchronous wheels 504 connected thereto to rotate. 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 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 inspects 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, and a component force is generated obliquely downward along the conveying direction of the conveyor belt, causing the conveyor belt to move. The material is reversely rotated and sent back. After the detector 600 detects that the material is 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 each air channel 2010 under the connection of a hose. The high-pressure gas pumped into the air channel 2010 then enters 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, and forms an upper and lower clamping effect on the edge of the conveyor belt with the lower brake pad 203, braking the conveyor belt, inhibiting 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 upper brake pad 206 moves downward and 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 to move downward. The trapezoidal slider 303 moves downward and 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 connection effect of the connecting rod 306, so that the bottom of the friction plate 308 fits on the bottom wall of the I-shaped guide rail, and brakes 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-line 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 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.

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