Description

Technical Field

[0001] The invention belongs to the technical field of conveyor belts, and in particular relates to a conveyor belt inclination detection device and a detection method thereof. Background Art

[0002] Conveyor belt systems are widely used in industrial production, especially in long-distance material transportation. The stable operation of conveyor belts is crucial to improving production efficiency and reducing equipment maintenance costs. However, in actual applications, conveyor belts often deviate, especially in long-distance transportation, the deviation of conveyor belts tends to increase significantly with the increase of transportation distance. Conveyor belt deviation not only reduces material transportation efficiency, but also may cause abnormal wear of conveyor belts and related components, thereby increasing maintenance costs and equipment downtime.

[0003] In order to solve the problem of conveyor belt deviation, various solutions have been proposed in the prior art. For example, some conveyor belt systems are equipped with horizontal adjustment devices to avoid deviation by manually adjusting the position of the conveyor belt; however, such devices are usually covered by protective covers, and the running status of the conveyor belt cannot be directly observed, making it difficult to detect and correct deviation in time. In addition, some conveyor systems have introduced automatic deviation correction devices, which use sensors to detect the position of the conveyor belt and automatically adjust it, but such devices are expensive and complex, and are not suitable for occasions with high economic requirements.

[0004] Guide rollers are also a common solution, which use their guiding function to keep the conveyor belt running track. However, guide rollers will increase friction and wear on the edge of the conveyor belt, and when the conveyor belt deviates at a large angle, the guide rollers are difficult to effectively play a corrective role. Therefore, existing deviation solutions have problems such as high cost, lack of flexibility, and untimely detection and correction, which cannot fully meet the needs of conveyor belt systems in industrial production.

[0005] Based on this, there is an urgent need for a device that can timely and accurately detect the inclination state of the conveyor belt, and the device has low cost, simple structure, high reliability, and can effectively solve the problem of conveyor belt deviation. Summary of the invention

The H-shaped bracket is arranged at an angle, and the tensioning roller connected to one end of the H-shaped bracket is against the lower surface of the conveyor belt, and the H-shaped bracket is located below the tensioning roller and is installed with a cleaning mechanism for cleaning the tensioning roller.

[0011] As an optimal technical solution, the detection mechanism includes a fixed seat slidably mounted on a fixed rod, the fixed seat is fixed by a locking bolt, the side of the fixed seat is fixedly connected to a support rod, the support rod includes a horizontal section and a vertical section, a bearing is installed on the upper end of the vertical section, a fixing ring is fixedly connected to the outer circumference of the outer ring of the bearing, a cylindrical pressure block is also slidably inserted on the vertical section, the lower end of the cylindrical pressure block is provided with an embedding groove matching the fixing ring, a spring is connected between the cylindrical pressure block and the fixing ring, the upper end of the spring abuts against the cylindrical pressure block located in the embedding groove, the other end of the spring abuts against the fixing ring, and the lower end face of the cylindrical pressure block is provided with a plum blossom-shaped tooth.

[0012] As a preferred technical solution, the upper end surface of the cylindrical pressing block is arranged in an arc shape, and arc grooves are evenly opened on the arc surface of the cylindrical pressing block, and a limiting plate is connected to one end of the cylindrical pressing block close to the arc.

[0013] As a preferred technical solution, the vertical section is located below the bearing and is rotatably connected to a turntable, a circle of impact bumps is provided on the outer circumference of the turntable, the outer ends of the impact bumps are circular, and a slot matching the plum blossom-shaped teeth is provided on the top of the turntable.

[0014] As an optimal technical solution, a mounting seat is fixedly installed on the horizontal section, a metal sound tube is fixedly connected to one side above the mounting seat, a spring is fixedly connected to the other end of the metal sound tube, and a sound-emitting component matching the impact bump is fixedly connected to the other end of the spring. The sound-emitting component includes a metal block arranged in a semicircular shape, a side of the metal block close to the impact bump is in an arc shape, and a cavity structure is provided on the side of the metal block close to the metal sound tube. When the impact bump hits the sound-emitting component, the sound-emitting component produces a "ding ding" sound, which is convenient for the staff to promptly detect the inclination of the conveyor belt.

[0016] A detection method for a conveyor belt inclination detection device comprises the following steps:

[0017] S1: The tension roller is subjected to downward pressure from the conveyor belt, causing the outer end of the roller cantilever beam to tend to deform downward. When the conveyor belt is conveying heavy objects, the outer end of the roller cantilever beam is forced to tilt downward, and the tension roller also tilts, causing the conveyor belt to deviate;

[0018] S2: The detection mechanism is set at the outer end of the roller cantilever beam. When the conveyor belt deviates, the outer side of the conveyor belt is suspended from the tensioning roller, causing the outer end of the conveyor belt to move and press on the arc surface of the cylindrical pressing block. As the conveyor belt continues to move, the conveyor belt will drive the cylindrical pressing block to rotate;

[0019] S3: When the cylindrical pressing block is squeezed, the cylindrical pressing block moves downward along the vertical section of the support rod, and at the same time, the cylindrical pressing block is in a rotating state, and the plum blossom-shaped teeth at the lower end of the cylindrical pressing block will be stuck in the slot of the turntable, thereby driving the turntable to rotate;

[0020] S4: When the turntable rotates, the impact bumps on the turntable will hit the metal block, causing the metal block to make a "ding ding" sound, thereby reminding the staff to promptly discover the problem of the conveyor belt's tilting and deviation, and then adjust the height of the outer end of the roller cantilever beam through the adjustment mechanism.

[0021] In summary, the present invention mainly has the following beneficial effects:

[0022] The structural design of the conveyor belt inclination detection device in the present application enables the conveyor belt inclination state to be effectively detected at the first time, especially through the arc surface of the cylindrical pressure block contacting the outer end of the conveyor belt. When the conveyor belt is tilted, the outer side will press on the cylindrical pressure block, and the cylindrical pressure block will rotate accordingly. The cylindrical pressure block can trigger the rotation action when the conveyor belt is slightly tilted, thereby improving the detection sensitivity. Compared with the solutions in the prior art that rely on manual observation or monitor the conveyor belt status through guide rollers, the detection device of the present application can effectively avoid the hysteresis and error problems in traditional detection methods, ensuring that the conveyor belt inclination problem can be discovered in time. In addition, the rotation of the turntable drives the impact protrusion to hit the metal block, producing a clear "ding ding" sound, which not only provides an audible alarm signal, but also avoids the disadvantage of requiring continuous manual monitoring, further improving the practicality and ease of operation of the device. This design reduces the impact of serious deviation of the conveyor belt on equipment and material transportation.

[0023] When the conveyor belt deviates briefly but the roller cantilever beam does not tilt, the cylindrical pressure block contacts the conveyor belt, but the pressure it exerts is insufficient to overcome the elastic force of the spring, so the cylindrical pressure block will not start the turntable and will not trigger the sound component. This design can effectively reduce the occurrence of false alarms, avoid unnecessary operations caused by false alarms, and improve the reliability and practicality of the system.

DETAILED DESCRIPTION

[0038] The invention of this application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In order to clearly and completely describe the technical solution, the following embodiments are selected for illustration; based on the contents recorded in this application, other embodiments obtained without creative work are all within the scope of protection of the present invention.

[0039] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of clearly describing the present embodiment, rather than indicating or implying that the device or element referred to must have a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0040] The following is combined with Figure 1-13 This application is described in further detail. Example

[0041] Conveyor belts are important equipment widely used in industrial production for continuous material transportation. However, in actual applications, conveyor belts often have systematic deviation problems during operation. This phenomenon is particularly obvious in long-distance conveying equipment, and the deviation of the conveyor belt increases with the increase of the equipment length. Deviation problems not only affect the conveying efficiency, but may also cause excessive wear of the conveyor belt and related components, increasing equipment maintenance costs and downtime.

[0042] In the prior art, a variety of solutions have been adopted to deal with the problem of conveyor belt deviation, such as:

[0043] Horizontal adjustment device: Some conveyor belt systems are equipped with horizontal adjustment devices, which can be used to adjust the balance of the conveyor belt when the conveyor belt deflects. However, the outside of the conveyor belt is usually covered with a cover that completely covers the conveyor belt. Although this is beneficial to safety and environmental protection, it also brings new problems: the staff cannot directly observe the running status of the conveyor belt and it is difficult to find deviation problems in time; due to the inability to directly observe, the deviation problem may not be discovered until it causes serious wear.

[0044] Automatic deviation correction device: Some advanced conveying systems use automatic deviation correction devices, which detect the position of the conveyor belt through sensors and automatically adjust it. However, this type of deviation correction device is expensive.

[0045] Guide rollers are used to control the direction of the conveyor belt. However, guide rollers may increase friction and wear on the sides of the conveyor belt and cannot fundamentally solve the problem of conveyor belt deviation. In some cases, they may not be able to effectively handle large angle deviations.

[0046] Therefore, it is necessary to develop a low-cost device that can promptly detect and correct conveyor belt deviation. In order to solve the above problems, the present application discloses a conveyor belt inclination detection device, a frame 100, a conveyor belt 200 installed on the frame 100, a pull rod assembly 300, a tensioning mechanism 400, a detection mechanism 500 and an adjustment mechanism 600.

[0047] The frame 100 includes an integrally connected fixing portion 110 and a supporting portion 120, the supporting portion 120 is connected above the fixing portion 110 and close to the outer side, a supporting cross plate 130 and a roller cantilever beam 140 are fixedly installed on the side of the supporting portion 120, and a tie rod assembly 300 connects the supporting cross plate 130 and the roller cantilever beam 140. The tensioning mechanism 400 is fixedly installed on the side of the roller cantilever beam 140 by bolts, and is used to adjust the tension of the conveyor belt 200. The detection mechanism 500 is installed on the tie rod assembly 300, and is used to detect the inclination state of the conveyor belt 200. The adjustment mechanism 600 is installed at the lower end of the tie rod assembly 300, and is used to adjust the height of the outer end of the roller cantilever beam 140.

[0048] The detection mechanism 500 is installed at the outer end of the roller cantilever beam 140, and can timely capture the tilt state of the conveyor belt 200, solving the problem in the prior art that it is difficult to visually observe the running state of the conveyor belt.

[0049] The adjusting mechanism 600 can adjust the height of the outer end of the roller cantilever beam 140, thereby correcting the inclination of the conveyor belt 200, which is lower in cost and more flexible and accurate than the automatic deviation correction device in the prior art.

[0050] The whole device has a simple structure and low cost, and is more economical than expensive automatic deviation-correcting devices.

[0051] The device also reduces friction and wear on the sides of the conveyor belt, avoiding the problems that may arise from the use of guide rollers.

[0052] The pull rod assembly 300 includes an L-shaped connecting rod 310, both ends of the connecting rod 310 are integrally connected with an inwardly bent edge A311, a fixed rod 312 is connected between the two folded edges A311, the detection mechanism 500 is installed on the fixed rod 312, the lower end of the connecting rod 310 is integrally connected with an outwardly bent edge B313, and the adjustment mechanism 600 is installed on the folded edge B313. The L-shaped structural design of the connecting rod 310 enables the pull rod assembly 300 to connect the supporting cross plate 130 and the roller cantilever beam 140, and provide an installation position for the detection mechanism 500 and the adjustment mechanism 600, with a compact structure and high structural strength.

[0053] The tensioning mechanism 400 includes two groups of L-shaped fixing brackets 410 fixedly installed on the side of the roller cantilever beam 140 by bolts, an H-shaped bracket 420 is installed between the two groups of L-shaped fixing brackets 410, both ends of the H-shaped bracket 420 are rotatably connected with tensioning rollers 430, a plurality of positioning holes 421 are opened on the side of the H-shaped bracket 420, and a positioning pin 440 matching the positioning hole 421 is slidably connected to the L-shaped fixing bracket 410. The H-shaped bracket 420 is inclined, and the tensioning roller 430 connected to one end of the H-shaped bracket 420 is against the lower surface of the conveyor belt 200. The H-shaped bracket 420 is located below the tensioning roller 430 and is installed with a cleaning mechanism 450 for cleaning the tensioning roller 430.

[0054] The inclined setting of the H-shaped bracket 420 enables the tensioning roller 430 to better fit the conveyor belt 200 and improve the tensioning effect. The design of multiple positioning holes 421 and positioning pins 440 makes the tensioning degree adjustable to meet the requirements of different working conditions. The setting of the cleaning mechanism 450 can keep the tensioning roller 430 clean and reduce the problem of conveyor belt deviation caused by the accumulation of pollutants.

[0055] Specifically, the cleaning mechanism 450 includes a U-shaped frame 451 installed on the lower side of the H-shaped bracket 420, and a scraper bar 452 is installed on the U-shaped frame 451. The scraper bar 452 is arranged below the tensioning roller 430, and the scraper bar 452 is close to the tensioning roller 430. When the tensioning roller 430 rotates, the scraper bar 452 is used to clean the contaminants on the surface of the tensioning roller 430. An arc-shaped protrusion 453 is arranged on the side of the U-shaped frame 451 close to the detection mechanism 500.

[0056] Furthermore, the detection mechanism 500 includes a fixed seat 510 slidably mounted on the fixed rod 312, the fixed seat 510 is fixed by a locking bolt, and a support rod 520 is fixedly connected to the side of the fixed seat 510, the support rod 520 includes a horizontal section 521 and a vertical section 522, a bearing 530 is installed on the upper end of the vertical section 522, a fixing ring 540 is fixedly connected to the outer circumference of the outer ring of the bearing 530, and a cylindrical pressure block 550 is also slidably inserted on the vertical section 522, and a groove 551 matching the fixing ring 540 is provided at the lower end of the cylindrical pressure block 550, and a spring 560 is connected between the cylindrical pressure block 550 and the fixing ring 540, the upper end of the spring 560 abuts against the cylindrical pressure block 550 and is located in the groove 551, and the other end of the spring 560 abuts against the fixing ring 540, and a plum blossom-shaped tooth 552 is provided on the lower end face of the cylindrical pressure block 550.

[0057] The upper end surface of the cylindrical pressing block 550 is arranged in an arc shape, and arc grooves 553 are evenly opened on the arc surface of the cylindrical pressing block 550. The end of the cylindrical pressing block 550 close to the arc is connected to a limiting piece 554, and the outer periphery of the limiting piece 554 is upwardly warped.

[0058] The vertical section 522 is located below the bearing 530 and is rotatably connected to a turntable 570 . A circle of impact bumps 571 are arranged on the outer circumference of the turntable 570 . The outer ends of the impact bumps 571 are circular. A slot 572 matching the plum blossom-shaped teeth 552 is arranged on the top of the turntable 570 .

[0059] A mounting base 580 is fixedly installed on the horizontal section 521, and a metal sound tube 590 is fixedly connected to one side above the mounting base 580, and a spring 591 is fixedly connected to the other end of the metal sound tube 590, and the other end of the spring 591 is fixedly connected to a sound-generating component 592 matching the impact bump 571. The sound-generating component 592 includes a metal block 593 arranged in a semicircular shape, and the side of the metal block 593 close to the impact bump 571 is in an arc shape, and a cavity structure is provided on the side of the metal block 593 close to the metal sound tube 590. When the impact bump 571 hits the sound-generating component 592, the sound-generating component 592 makes a "ding ding" sound, which is convenient for the staff to promptly detect the inclination of the conveyor belt 200.

[0060] The impact protrusion 571 on the turntable 570 can also cooperate with the arc-shaped protrusion 453 on one side of the U-shaped frame 451. The impact protrusion 571 hits the arc-shaped protrusion 453 to vibrate the U-shaped frame 451, thereby vibrating the scraper bar 452 to achieve the purpose of vibrating off the residual pollutants on the scraper bar 452.

[0061] When the conveyor belt 200 tilts, its outer side will press on the arc surface of the cylindrical pressing block 550, driving the cylindrical pressing block 550 to rotate. The radius of the arc surface of the cylindrical pressing block 550 is 60mm, which can trigger the rotation when the conveyor belt 200 tilts at a certain angle (the tilt angle of the conveyor belt 200 when triggering rotation is related to the length, width and tension of the conveyor belt), thereby improving the detection sensitivity.

[0062] The cylindrical pressing block 550 moves downward along the vertical section 522 while rotating, and the plum blossom-shaped tooth 552 at the lower end thereof is inserted into the slot 572 of the turntable 570, driving the turntable 570 to rotate. When the turntable 570 rotates, the impact protrusion 571 thereon will hit the metal block 593, producing a "ding ding" sound, reminding the staff that the conveyor belt 200 is tilted. The turntable 570 has a diameter of 90 mm and a thickness of 10 mm. There are no less than 3 impact protrusions 571, and the height of the impact protrusions 571 is 5 mm. The hemispherical design on the top ensures that a clear sound signal can be generated each time the impact occurs.

[0063] However, the present application also takes into account the short-term deviation of the conveyor belt 200 during operation to avoid false detection. For example, when the conveyor belt 200 deviates briefly, but the roller cantilever beam 140 does not tilt, the cylindrical pressing block 550 is in contact with the conveyor belt 200, but because the pressure applied by it is not enough to overcome the elastic force of the spring 560, the cylindrical pressing block 550 will not start the turntable 570, and will not trigger the sound component 592. It can effectively reduce the occurrence of false alarms, avoid unnecessary operations caused by false alarms by staff, and improve the reliability and practicality of the system.

[0064] The arc groove 553 on the cylindrical pressing block 550 is designed to be 3.5 mm wide and 3 mm deep, and a total of several arc grooves are provided. The limiting piece 554 protrudes 10 mm from the upper surface of the cylindrical pressing block 550, which can prevent the conveyor belt 200 from further deflecting, thereby playing a limiting role.

[0065] The provision of the spring 560 enables the cylindrical pressing block 550 to automatically reset after the detection is completed, thereby ensuring the continuous availability of the detection mechanism.

[0066] The metal sound tube 590 is 100 mm long, 20 mm in inner diameter, and 2.5 mm in wall thickness. The metal block 593 with a hollow structure can generate clear sound signals, making it easy for the staff to hear the sound in time.

[0067] The adjustment mechanism 600 includes a screw rod 610 threadedly connected to the folded edge B313 , one end of the screw rod 610 abuts against the lower side of the roller cantilever beam 140 , and a screw cap 620 is provided at the other end of the screw rod 610 .

[0068] When the staff hears the "ding ding" sound, the conveyor belt 200 may be deviated. The staff adjusts the screw nut 620 and the screw rod 610 by turning the screw nut 620 and the screw rod 610. The screw rod 610 rises and falls, and the screw rod 610 rests under the outer end of the roller cantilever beam 140 to adjust the height of the outer end of the roller cantilever beam 140. Example

[0069] This application also discloses a detection method of a conveyor belt inclination detection device, see Figure 11-13 , including the following steps:

[0070] S1: The tension roller 430 is subjected to downward pressure from the conveyor belt 200, so that the outer end of the roller cantilever beam 140 tends to deform downward. When the conveyor belt 200 conveys heavy objects, the outer end of the roller cantilever beam 140 is forced to tilt downward, and the tension roller 430 also tilts accordingly, causing the conveyor belt 200 to deviate;

[0071] S2: The detection mechanism 500 is arranged at the outer end of the roller cantilever beam 140. When the conveyor belt 200 deviates, the outer side of the conveyor belt 200 is suspended from the tensioning roller 430, causing the outer end of the conveyor belt 200 to move and be pressed on the arc surface of the cylindrical pressing block 550. When the conveyor belt 200 continues to move, the conveyor belt 200 will drive the cylindrical pressing block 550 to rotate.

[0072] S3: When the cylindrical pressing block 550 is squeezed, the cylindrical pressing block 550 moves downward along the vertical section 522 of the support rod 520, and at the same time, the cylindrical pressing block 550 is in a rotating state, and the plum blossom-shaped locking teeth 552 at the lower end of the cylindrical pressing block 550 will be stuck in the locking groove 572 of the rotating disk 570, thereby driving the rotating disk 570 to rotate;

[0073] S4: When the turntable 570 rotates, the impact protrusion 571 on the turntable 570 will hit the metal block 593, causing the metal block 593 to make a "ding ding" sound, thereby reminding the staff to promptly discover the tilt and deviation problem of the conveyor belt 200, and then adjust the height of the outer end of the roller cantilever beam 140 through the adjustment mechanism 600.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any slight modification, equivalent substitution and improvement made to the above embodiment based on the technical essence of the present invention should be included in the protection scope of the technical solution of the present invention.

The H-shaped bracket is arranged at an angle, and the tensioning roller connected to one end of the H-shaped bracket is against the lower surface of the conveyor belt, and the H-shaped bracket is located below the tensioning roller and is installed with a cleaning mechanism for cleaning the tensioning roller.

4. A conveyor belt inclination detection device according to claim 3, characterized in that: The sound-generating component includes a metal block arranged in a semicircular shape, and the side of the metal block close to the impact protrusion is arc-shaped. The side of the metal block close to the metal sound tube is provided with a cavity structure. When the impact protrusion hits the sound-generating component, the sound-generating component makes a "ding ding" sound, which is convenient for the staff to detect the inclination of the conveyor belt in time.

5. A conveyor belt inclination detection device according to claim 4, characterized in that: The adjusting mechanism comprises a screw rod which is threadedly connected to the folded edge B, one end of the screw rod is against the lower side of the cantilever beam of the roller, and the other end of the screw rod is provided with a screw cap.

6. A detection method of a conveyor belt inclination detection device, implemented based on the conveyor belt inclination detection device of claim 5, characterized in that: The steps include: S1: The tension roller is subjected to downward pressure from the conveyor belt, causing the outer end of the roller cantilever beam to tend to deform downward. When the conveyor belt is conveying heavy objects, the outer end of the roller cantilever beam is forced to tilt downward, and the tension roller also tilts, causing the conveyor belt to deviate; S2: The detection mechanism is set at the outer end of the roller cantilever beam. When the conveyor belt deviates, the outer side of the conveyor belt is suspended from the tensioning roller, causing the outer end of the conveyor belt to move and press on the arc surface of the cylindrical pressing block. As the conveyor belt continues to move, the conveyor belt will drive the cylindrical pressing block to rotate; S3: When the cylindrical pressing block is squeezed, the cylindrical pressing block moves downward along the vertical section of the support rod, and at the same time, the cylindrical pressing block is in a rotating state, and the plum blossom-shaped teeth at the lower end of the cylindrical pressing block will be stuck in the slot of the turntable, thereby driving the turntable to rotate; S4: When the turntable rotates, the impact bumps on the turntable will hit the metal block, causing the metal block to make a "ding ding" sound, thereby reminding the staff to promptly discover the problem of the conveyor belt's tilt and deviation, and then adjust the height of the outer end of the roller cantilever beam through the adjustment mechanism.
