Description

Technical Field

[0001] The present 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, playing an irreplaceable role in long-distance material transport. Stable conveyor belt operation is crucial to improving production efficiency and reducing equipment maintenance costs. However, in practice, conveyor belts often deviate, especially over long distances, where the amount of deviation increases significantly with increasing transport distance. This deviation not only reduces material conveying efficiency but can also cause abnormal wear on the conveyor belt and related components, increasing maintenance costs and equipment downtime.

[0003] To address the problem of conveyor belt deviation, various solutions have been proposed in the prior art. For example, some conveyor belt systems are equipped with leveling devices that manually adjust the belt's position to prevent deviation. However, these devices are often covered by protective covers, preventing direct observation of the belt's operating status, making it difficult to detect and correct deviations in a timely manner. Furthermore, some conveyor systems incorporate automatic deviation-correcting devices that use sensors to detect the belt's position and automatically adjust it. However, these devices are expensive and complex, making them unsuitable for applications requiring high economic efficiency.

[0004] Guide rollers are another common solution, leveraging their guiding function to maintain the conveyor belt's trajectory. However, these rollers increase friction and wear on the belt's edges, and they are unable to effectively correct the belt's deviation when it deviates significantly. Consequently, existing deviation solutions suffer from high costs, limited flexibility, and delayed detection and correction, failing to fully meet the demands 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 tilt state of the conveyor belt, and the device is low-cost, simple in structure, and highly reliable, and can effectively solve the problem of conveyor belt deviation. Summary of the Invention

[0006] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide a conveyor belt inclination detection device and a detection method thereof to solve the problems raised in the background technology.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: A conveyor belt inclination detection device comprises a frame and a conveyor belt mounted on the frame, the frame comprising an integrally connected fixing portion and a supporting portion, the supporting portion being connected above the fixing portion and close to the outside, a supporting cross plate and a roller cantilever beam being fixedly mounted on the side of the supporting portion, a pull rod assembly being connected between the supporting cross plate and the roller cantilever beam, a tensioning mechanism for adjusting the tension of the conveyor belt being fixedly mounted on the side of the roller cantilever beam by bolts, a detection mechanism for detecting the inclination of the conveyor belt being mounted on the pull rod assembly, and an adjustment mechanism for adjusting the height of the outer end of the roller cantilever beam being mounted on the lower end of the pull rod assembly.

[0008] As an optimal technical solution, the pull rod assembly includes an L-shaped connecting rod, the two ends of the connecting rod are integrally connected with an inward-bent folded edge A, a fixed rod is connected between the two folded edges A, the detection mechanism is installed on the fixed rod, the lower end of the connecting rod is integrally connected with an outward-bent folded edge B, and the adjustment mechanism is installed on the folded edge B.

[0009] As an optimal technical solution, the tensioning mechanism includes two groups of L-shaped fixing brackets fixedly installed on the side of the roller cantilever beam by bolts, an H-shaped bracket is installed between the two groups of L-shaped fixing brackets, both ends of the H-shaped bracket are rotatably connected to the tensioning roller, a plurality of positioning holes are opened on the side of the H-shaped bracket, and the L-shaped fixing bracket is slidably connected with a positioning pin matching the positioning holes. 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.

[0010] As an optimal technical solution, the detection mechanism includes a fixing seat slidably mounted on a fixing rod, the fixing seat is fixed by a locking bolt, the side of the fixing seat is fixedly connected to a support rod, the support rod includes a horizontal section and a vertical section, the upper end of the vertical section is equipped with a bearing, a fixing ring is fixedly connected to the outer periphery of the outer ring of the bearing, and a cylindrical pressure block is also slidably inserted into 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 rests on the cylindrical pressure block located in the embedding groove, the other end of the spring rests on the fixing ring, and the lower end face of the cylindrical pressure block is provided with a plum blossom-shaped latch.

[0011] 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. The end of the cylindrical pressing block close to the arc is connected to a limiting plate.

[0012] As an optimal 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. A slot matching the plum blossom-shaped teeth is provided above the turntable.

[0013] 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 the other end of the spring is fixedly connected to a sound-generating component that matches the impact bump. The sound-generating component includes a metal block arranged in a semicircular shape, the side of the metal block close to the impact bump is arc-shaped, 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-generating component, the sound-generating component produces a "ding ding" sound, which is convenient for staff to promptly detect the inclination of the conveyor belt.

[0014] As an optimal technical solution, the adjustment mechanism includes a screw rod threaded through and connected to the folded edge B, one end of the screw rod rests on the lower side of the roller cantilever beam, and the other end of the screw rod is provided with a screw cap.

[0015] A detection method for a conveyor belt inclination detection device comprises the following steps: S1: The tension roller is subjected to downward pressure from the conveyor belt, causing the outer end of the roller cantilever beam to deform downward. When the conveyor belt is transporting 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-shaped surface of the cylindrical pressure block. As the conveyor belt continues to move, the conveyor belt will drive the cylindrical pressure block to rotate; S3: When the cylindrical pressing block is squeezed, it moves downward along the vertical section of the support rod. 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, making the metal block make a "ding ding" sound, thereby reminding the staff to promptly discover the problem of conveyor belt tilting and deviation, and then adjust the height of the outer end of the roller cantilever beam through the adjustment mechanism.

[0016] In summary, the present invention mainly has the following beneficial effects: 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-shaped 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 existing solutions 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, generating 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.

[0017] If the conveyor belt briefly deviates but the roller cantilever beam does not tilt, the cylindrical pressure block, while in contact with the conveyor belt, does not exert sufficient pressure to overcome the spring force, preventing the turntable from activating and the sounding component from being triggered. This design effectively reduces false alarms, avoiding unnecessary operations caused by false alarms and improving the reliability and practicality of the system. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The invention of this application is further described in detail below with reference to the accompanying drawings and specific embodiments. In order to clearly and completely describe the technical solution, the following embodiments are selected for illustration; other embodiments obtained based on the contents recorded in this application without creative work are all within the scope of protection of this invention.

[0021] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", "top / bottom", etc., or the like, are based on the terms or the like as shown in the accompanying drawings. They are only for the purpose of clearly describing the present embodiment, and do not indicate or imply that the device or element referred to must have a specific orientation. Therefore, they should not be understood as limiting the present application.

[0022] The following is combined with Figure 1-13 This application is described in further detail. Example

[0023] Conveyor belts are essential equipment widely used in industrial production, ensuring the continuous transport of materials. However, in practice, conveyor belts often experience systematic deviation during operation. This phenomenon is particularly pronounced in long-distance conveying equipment, where belt deviation increases with the length of the equipment. Deviation not only affects conveying efficiency but can also cause excessive wear on the conveyor belt and related components, increasing maintenance costs and downtime.

[0024] There are many solutions available in the prior art to address the problem of conveyor belt deviation, such as: Leveling devices: Some conveyor belt systems are equipped with leveling devices to adjust the belt's balance if it deflects. However, these devices are often completely covered by a belt cover. While this improves safety and environmental protection, it also creates a new problem: workers cannot directly observe the conveyor belt's operating status, making it difficult to detect deviations in a timely manner. Without direct observation, deviations may not be discovered until they have caused significant wear.

[0025] Automatic deviation-correcting device: Some advanced conveying systems use automatic deviation-correcting devices, which detect the position of the conveyor belt through sensors and automatically adjust it. However, this type of deviation-correcting device is expensive.

[0026] 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.

[0027] 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, which includes 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.

[0028] 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 near the outside. A supporting cross plate 130 and a roller cantilever beam 140 are fixedly mounted on the side of the supporting portion 120. The tie rod assembly 300 connects the supporting cross plate 130 and the roller cantilever beam 140. The tensioning mechanism 400 is fixedly mounted 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 mounted on the tie rod assembly 300 and is used to detect the inclination state of the conveyor belt 200. The adjustment mechanism 600 is mounted on 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.

[0029] 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.

[0030] The adjustment 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. It is lower in cost and more flexible and accurate than the automatic deviation correction device in the prior art.

[0031] The entire device has a simple structure and low cost, and is more economical than expensive automatic deviation-correcting devices.

[0032] Furthermore, the device reduces friction and wear on the sides of the conveyor belt, avoiding the problems that may arise from the use of guide rollers.

[0033] The pull rod assembly 300 includes an L-shaped connecting rod 310, and the two ends of the connecting rod 310 are integrally connected with an inward-bent folded edge A311, and a fixed rod 312 is connected between the two folded edges A311. The detection mechanism 500 is installed on the fixed rod 312, and the lower end of the connecting rod 310 is integrally connected with an outward-bent folded 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. The structure is compact and the structural strength is high.

[0034] 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, and 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 to the tensioning roller 430. A plurality of positioning holes 421 are opened on the side of the H-shaped bracket 420. A positioning pin 440 matching the positioning holes 421 is slidably connected to the L-shaped fixing bracket 410. The H-shaped bracket 420 is arranged at an angle, 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.

[0035] The inclined setting of the H-shaped bracket 420 enables the tensioning roller 430 to better fit the conveyor belt 200, thereby improving 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.

[0036] 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 provided on the side of the U-shaped frame 451 close to the detection mechanism 500.

[0037] Furthermore, the detection mechanism 500 includes a fixing seat 510 slidably mounted on the fixing rod 312, and the fixing seat 510 is fixed by a locking bolt. The side of the fixing seat 510 is fixedly connected to the support rod 520, and 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, and a fixing ring 540 is fixedly connected to the outer periphery of the outer ring of the bearing 530. A cylindrical pressure block 550 is also slidably inserted into the vertical section 522. The lower end of the cylindrical pressure block 550 is provided with an embedding groove 551 that matches the fixing ring 540. A spring 560 is connected between the cylindrical pressure block 550 and the fixing ring 540. The upper end of the spring 560 rests on the cylindrical pressure block 550 and is located in the embedding groove 551. The other end of the spring 560 rests on the fixing ring 540. The lower end face of the cylindrical pressure block 550 is provided with a plum blossom-shaped locking tooth 552.

[0038] 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 curved.

[0039] 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 provided on the outer periphery 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 provided on the top of the turntable 570 .

[0040] 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. 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 component 592 that matches the impact bump 571. The sound component 592 includes a semicircular metal block 593, and the side of the metal block 593 close to the impact bump 571 is arc-shaped. 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 component 592, the sound component 592 produces a "ding ding" sound, which makes it easy for staff to promptly detect the inclination of the conveyor belt 200.

[0041] The impact bump 571 on the turntable 570 can also cooperate with the arc-shaped bump 453 on one side of the U-shaped frame 451. The impact bump 571 hits the arc-shaped bump 453 to vibrate the U-shaped frame 451, thereby vibrating the scraper 452 to achieve the purpose of vibrating off the residual pollutants on the scraper 452.

[0042] When conveyor belt 200 tilts, its outer side presses against the arcuate surface of cylindrical pressure block 550, causing it to rotate. The arcuate surface of cylindrical pressure block 550 has a radius of 60mm, triggering rotation at a certain angle of conveyor belt 200 tilt (the angle at which rotation is triggered depends on the belt's length, width, and tension), improving detection sensitivity.

[0043] As cylindrical pressure block 550 rotates, it moves downward along vertical section 522. The plum blossom-shaped teeth 552 at its lower end engage slots 572 in turntable 570, driving the turntable 570 to rotate. As turntable 570 rotates, its impact bumps 571 strike metal block 593, producing a "ding-ding" sound, alerting personnel that conveyor belt 200 is tilted. Turntable 570 has a diameter of 90 mm and a thickness of 10 mm. It has no fewer than three impact bumps 571, each 5 mm high and with a hemispherical top design, ensuring each impact produces a clear audible signal.

[0044] However, the present application also takes into account brief deviations during the operation of the conveyor belt 200 to avoid false detections. For example, when the conveyor belt 200 briefly deviates but the roller cantilever beam 140 does not tilt, the cylindrical pressure block 550, although in contact with the conveyor belt 200, will not activate the turntable 570 because the pressure it applies is insufficient to overcome the elastic force of the spring 560, and thus will not trigger the sounding component 592. This 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.

[0045] The arc groove 553 on the cylindrical pressing block 550 is designed to be 3.5mm wide and 3mm deep, and is provided in a plurality of strips. The limiting piece 554 protrudes 10mm from the upper surface of the cylindrical pressing block 550 to prevent the conveyor belt 200 from further deflecting, thereby playing a limiting role.

[0046] 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.

[0047] 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 easier for staff to hear the sound in time.

[0048] The adjustment mechanism 600 includes a screw rod 610 that is 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 the other end of the screw rod 610 is provided with a screw cap 620 .

[0049] When the staff hears the "ding ding" sound, the conveyor belt 200 may be running off track. 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

[0050] This application also discloses a detection method for a conveyor belt inclination detection device, see Figure 11-13 , including the following steps: S1: The tension roller 430 is subjected to downward pressure from the conveyor belt 200, causing the outer end of the roller cantilever beam 140 to tend to deform downward. When the conveyor belt 200 is conveying 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. 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 press against the arc-shaped surface of the cylindrical pressing block 550. As the conveyor belt 200 continues to move, the conveyor belt 200 will drive the cylindrical pressing block 550 to rotate. S3: When the cylindrical pressing block 550 is squeezed, it moves downward along the vertical section 522 of the support rod 520. At the same time, the cylindrical pressing block 550 is in a rotating state. The plum blossom-shaped teeth 552 at the lower end of the cylindrical pressing block 550 are stuck in the slots 572 of the turntable 570, thereby driving the turntable 570 to rotate. 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.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent replacements, and improvements made to the above embodiments based on the technical essence of the present invention shall be included in the scope of protection of the technical solution of the present invention.

9. A detection method for a conveyor belt inclination detection device, implemented based on the conveyor belt inclination detection device according to any one of claims 1 to 8, characterized in that: The steps include: S1: The tensioning roller (430) is subjected to downward pressure from the conveyor belt (200), causing the outer end of the roller cantilever beam (140) to tend 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 tensioning roller (430) also tilts accordingly, causing the conveyor belt (200) to deviate. 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-shaped surface of the cylindrical pressing block (550). As the conveyor belt (200) continues to move, the conveyor belt (200) will drive the cylindrical pressing block (550) to rotate. 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 teeth (552) at the lower end of the cylindrical pressing block (550) are stuck in the slots (572) of the turntable (570), thereby driving the turntable (570) to rotate; 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 emit a "ding ding" sound, thereby reminding the staff to promptly discover the tilting 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).
