Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0035] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0036] The embodiment of the present invention discloses a conveyor belt breakage detection device, which can solve the technical problem that the existing capture method easily causes secondary tearing of the belt.

[0037] The technical solution of this application is described in detail below through specific embodiments:

[0038] See Figure 1 and Figure 2 The embodiment of the present application discloses a conveyor belt break detection device, which includes a frame 100, a detection unit 200, a lifting unit 300, a capture unit 400, and a guide unit 500. The detection unit 200 includes a detection wheel 210 and a trigger box 220. The detection wheel 210 is rotatably connected to the frame 100 and supported below the belt. The trigger box 220 is used to monitor the rotation direction of the detection wheel 210. The lifting unit 300 includes a weight 310, a first connecting rope 320, a second connecting rope 330, and a lifting roller 340. The weight 310 and the lifting roller 340 are both slidably matched with the frame 100. The two ends of the first connecting rope 320 are respectively connected to the trigger box 220 and the weight 310, and the two ends of the second connecting rope 330 are respectively connected to the weight 310 and the lifting roller 340. The capture unit 400 includes a third connecting rope 410 and a damping capture head 420. The damping capture head 420 is located above the belt. The ends of the third connecting rope 410 are connected to the damping capture head 420 and the trigger box 220, respectively. The guide unit 500 is located on the connecting line between the detection unit 200 and the capture unit 400. When the detection wheel 210 rotates in the reverse direction, the trigger box 220 releases the restraints on the first and third connecting ropes 320, 410, causing the weight 310 to drop, driving the lifting roller 340 upward, causing the belt to rise, and the damping capture head 420 to squeeze the belt.

[0039] In this embodiment, see Figure 1 and Figure 3 The normal transmission direction of the belt is from left to right. The detection wheel 210 is in contact with the belt. The belt will drive the detection wheel 210 to rotate when it moves. The rotation direction of the detection wheel 210 when the belt moves from left to right is the positive direction, and the rotation direction of the detection wheel 210 when the belt moves from right to left is the positive direction.

[0040] The conveyor belt breakage detection device disclosed in this embodiment adopts a damping capture method, which uses the deadweight of the belt and the material to minimize the downward force of the belt, avoiding secondary tearing damage to the belt and increased peeling between material layers caused by direct capture, thereby extending the service life of the belt.

[0041] In one embodiment, the detection wheel 210 is supported below the belt, which can avoid affecting the goods conveyed by the belt. In this case, see Figure 1 When the belt works normally (from the seat to the right), the detection wheel 210 rotates counterclockwise.

[0042] In another embodiment, the detection wheel 210 can be placed above the belt. In this case, a certain position on the belt needs to be reserved for the detection wheel 210 to cooperate with it. For example, the two sides of the belt can be reserved. That is, when the belt is working and goods are placed on both sides, when the detection wheel 210 contacts the positions on both sides of the belt, the belt can also drive the detection wheel 210 to rotate. However, when the belt is working normally, the detection wheel 210 rotates clockwise.

[0043] See Figure 1 、 Figure 2 and Figure 3 In one embodiment, the detection wheel 210 includes a rubber wheel 211 and a ratchet 212. The ratchet 212 is coaxially arranged with the rubber wheel 211, and the diameter of the ratchet 212 is smaller than the diameter of the rubber wheel 211. A trigger head 221 is provided on the trigger box 220. The trigger head 221 is slidably connected to the trigger box 220, and the trigger head 221 cooperates with the ratchet 212, and the first connecting rope 320 and the third connecting rope 410 are clamped between the trigger head 221 and the trigger box 220. When the detection wheel 210 rotates in the reverse direction, the ratchet 212 drives the trigger head 221 to move and releases the restrictions on the first connecting rope 320 and the third connecting rope 410.

[0044] The design of rubber wheel 211 allows detection wheel 210 to better contact the belt, adapting to the belt's movement and reducing detection errors caused by uneven or slightly offset belt surfaces. The toothed structure of ratchet wheel 212 helps to more accurately determine the direction of rotation, reducing the possibility of misjudgment.

[0045] The trigger head 221 is slidably connected to the trigger box 220 and engages the ratchet 212. This design allows the ratchet 212 to quickly move the trigger head 221 when the detection wheel 210 rotates in the opposite direction, thereby releasing the first and third connecting ropes 320 and 410. This rapid response mechanism ensures that the protection mechanism can be quickly activated in the event of a belt breakage, improving safety. The sliding connection between the trigger head 221 and the trigger box 220 also increases system reliability, reducing the risk of trigger failure due to mechanical jamming or wear.

[0046] Of course, the use of the ratchet 212 structure to determine the forward and reverse rotation is only one implementation in this embodiment. In other implementations, it is also possible to use sensors or other auxiliary means to make the determination.

[0047] In one embodiment, a winding roller is disposed within the trigger box 220, around which both the first connecting rope 320 and the third connecting rope 410 are wound. When the trigger head 221 is in the initial position, the trigger head 221 restricts the winding roller, preventing it from rotating. At this point, the first connecting rope 320 pulls the weight 310, causing it to suspend in mid-air. When the third connecting rope 410 pulls the detection wheel 210 in the reverse direction, the ratchet 212 drives the trigger head 221 to move, releasing the restrictions on the first and third connecting ropes 320, 410, causing them to suspend above the belt.

[0048] When the trigger head 221 moves downward, the trigger head 221 releases the restriction on the winding roller, and the winding roller can rotate freely. That is, the first connecting rope 320 loses the restraint on the weight 310, and the third connecting rope 410 loses the restriction on the damping catch head 420. At this time, the weight 310 and the damping catch head 420 can both fall freely.

[0049] The provision of a winding roller within the trigger box 220 is merely one embodiment of this embodiment. In other embodiments, a clamping groove may be provided between the trigger head 221 and the trigger box 220 to clamp both the first connecting rope 320 and the third connecting rope 410 within the clamping groove. When the trigger head 221 is in its initial position, it clamps the first connecting rope 320 and the third connecting rope 410. As the trigger head 221 moves downward, the restraints on the first connecting rope 320 and the third connecting rope 410 are released, allowing the weight 310 and the damping catch head 420 to fall freely.

[0050] In one embodiment, a second elastic member is provided on the trigger box 220, and two ends of the second elastic member are respectively connected to the trigger box 220 and the trigger head 221. The second elastic member is used to drive the trigger head 221 back to the initial position.

[0051] The elastic force of the second elastic member can prevent the trigger head 221 from accidentally moving downward. The trigger head 221 will only move downward when the ratchet wheel 212 is reversed, thereby ensuring the accuracy of detection.

[0052] In one embodiment, a support arm 130 is provided on the frame 100 , and the rubber wheel 211 and the ratchet wheel 212 are respectively located on both sides of the support arm 130 .

[0053] The support arm 130 serves as an intermediate support structure, which can effectively disperse and withstand the force and vibration generated by the rubber wheel 211 and the ratchet wheel 212 during operation, thereby improving the overall stability of the device.

[0054] In one embodiment, the support arm 130 is rotatably connected to the frame 100 , and a first elastic member is provided between the support arm 130 and the frame 100 . The first elastic member is used to drive the support arm 130 to drive the detection wheel 210 to rotate upward.

[0055] During conveyor belt operation, belt tension may fluctuate due to changes in material load, belt expansion and contraction, or ambient temperature. The pivoting connection between support arm 130 and frame 100, coupled with the driving action of the first elastic member, enables detection wheel 210 to automatically adjust its position based on changes in belt tension. When belt tension decreases, the first elastic member drives support arm 130, causing detection wheel 210 to rotate upward, maintaining appropriate contact pressure between detection wheel 210 and the belt to ensure detection accuracy.

[0056] Driven by the first elastic member, the detection wheel 210 can contact the belt with appropriate pressure, avoiding belt wear caused by excessive pressure. This adaptive contact pressure adjustment helps extend the service life of the belt and reduce replacement costs for enterprises.

[0057] In one embodiment, two detection units 200 are provided, spaced apart in a direction perpendicular to the belt conveyor direction. Two first connecting ropes 320 and two second connecting ropes 330 are provided, each corresponding to one of the two trigger boxes 220. The ends of the two first connecting ropes 320 facing away from the trigger boxes 220 are connected to the weight 310. One end of each of the two second connecting ropes 330 is connected to the weight 310, and the other ends of the two second connecting ropes 330 are connected to the ends of the lifting and rolling mechanism, respectively.

[0058] By providing two detection units 200, spaced apart and perpendicular to the belt's direction of travel, comprehensive detection of the belt's operating status can be achieved. This redundant design ensures that even if one detection unit 200 fails or misjudges, the other detection unit 200 can still function normally, thereby improving detection reliability and accuracy.

[0059] In one embodiment, a trigger pulley 110, a lifting pulley 120, and a capture pulley 140 are provided on the frame 100. The trigger pulley 110 is located above the weight 310, the lifting pulley 120 is located above the lifting roller 340, and the capture pulley 140 is located above the damping capture head 420. The first connecting rope 320 is wound around the trigger pulley 110, the second connecting rope 330 is wound around the lifting pulley 120, and the third connecting rope 410 is wound around the capture pulley 140.

[0060] The first connecting rope 320, the second connecting rope 330 and the third connecting rope 410 can be wound along a preset path to avoid direct friction and entanglement of the ropes on the frame 100. This not only reduces rope wear and extends the service life of the ropes, but also improves the smoothness of rope movement.

[0061] See Figure 1 and Figure 4 In one embodiment, a damping catch head 420 is rotatably connected to the frame 100. The friction end of the damping catch head 420 is arc-shaped, and the distance between the first end of the friction end and the rotation axis is greater than the distance between the second end of the friction end and the rotation axis. A third connecting rope 410 is connected to the first end of the friction end.

[0062] The curved friction end can better fit the contour of the belt, increasing the contact area with the belt, thereby improving the friction during the capture. Friction is a crucial factor in the capture process, which directly determines the firmness of the capture.

[0063] The first end of the friction end is farther from the rotation axis than the second end. This asymmetric design allows the friction end to generate greater torque when the third connecting rope 410 pulls the first end of the friction end during the capture process, thereby more effectively securing the belt. This design enhances the capture force and capture effect of the capture head.

[0064] In one embodiment, the capture unit 400 further includes a fixed capture head 430. The fixed capture head 430 is located below the damping capture head 420, and the distance between the fixed capture head 430 and the rotation axis of the damping capture head 420 is smaller than the distance between the first end of the friction end and the rotation axis of the damping capture head 420.

[0065] The fixed catch head 430 is located below the damping catch head 420, forming a coordinated catch structure. If the damping catch head 420 is activated during the catch process due to an unexpected situation such as a belt breakage, the fixed catch head 430 can serve as a stable support point, helping the damping catch head 420 to better fix and catch the belt, thereby preventing the belt from slipping or falling off during the catch process and improving the stability of the catch.

[0066] In one embodiment, a plurality of detection units 200 and capture units 400 are provided along the length direction of the frame 100 , and each detection unit 200 cooperates with at least one capture unit 400 .

[0067] By providing a plurality of detection units 200 and capture units 400, the belt can be captured more quickly and accurately, thereby avoiding secondary damage to the belt.

[0068] See Figure 1 and Figure 5 In one embodiment, the guide unit 500 includes a support frame 510, two support rollers 520, and two belt guide pulleys 530. The two support rollers 520 are symmetrically arranged on either side of the support frame 510 and are arranged at an angle, forming a conveying area between the two support rollers 520. The two belt guide pulleys 530 are arranged in a one-to-one correspondence with the two support rollers 520, and are located in the direction of the support rollers 520, and are arranged at an angle to the support rollers 520.

[0069] The two support rollers 520 are symmetrically positioned at an angle, creating a specific conveying zone between them. This design guides the belt along a predetermined path, minimizing belt deviation or wobble during transport. The support rollers 520 not only provide the necessary support for the belt but also guide it through their angled arrangement. This design ensures the belt maintains its correct position and posture during transport, preventing conveyor failures caused by belt slack or deviation.

[0070] In one embodiment, a plurality of guide units 500 are provided, and each guide unit 500 is arranged at intervals along the connecting line between the detection unit 200 and the capture unit 400, and the interval distance between two adjacent guide units 500 is equal.

[0071] By providing multiple guide units 500 and distributing them at intervals along the connecting line between the detection unit 200 and the capture unit 400, the belt can be stably supported and guided throughout the entire conveying path. This design reduces the belt's deviation, shaking, or twisting during conveyance.

[0072] There are various arrangements of the guide unit 500, the detection unit 200, and the capture unit 400. For example, the detection unit 200 and the capture unit 400 may be disposed between two adjacent guide units 500, or one or more guide units 500 may be disposed between the detection unit 200 and the capture unit 400.

[0073] The conveyor belt breakage detection device disclosed in this application works as follows:

[0074] Initially, the weight 310 and the damping catch head 420 are both located above the belt, and the detection wheel 210 and the lifting roller 340 are both located below the belt.

[0075] The belt enters the conveying area under the guidance of the guide unit 500. The two support rollers 520 in the guide unit 500 are symmetrical and angled to form a stable conveying path, ensuring that the belt maintains the correct position and posture during the conveying process.

[0076] When the belt is operating normally, the detection wheel 210 maintains appropriate contact pressure with the belt through the action of the support arm 130 and the first elastic member, ensuring detection accuracy. When the belt is operating normally, the detection wheel 210 moves in the positive direction, and the ratchet 212 causes the trigger head 221 to move upward. At this time, the ratchet 212 can rotate normally, and the trigger head 221 can remain fixed, thereby clamping the first connecting rope 320 and the third connecting rope 410.

[0077] If the belt breaks or experiences an abnormality, it begins to reverse direction, driving the rubber wheel 211 and ratchet 212 in the opposite direction. The ratchet 212 then drives the trigger head 221 downward. As the trigger head 221 moves downward, it releases its grip on the first and third connecting cords 320 and 410.

[0078] After the first connecting rope 320 is loosened, the weight 310 loses its upward pulling force and moves downward under its own weight, and drives the lifting roller 340 to move upward through the second connecting rope 330. The lifting roller 340 lifts the belt to prevent the belt from sliding downward.

[0079] After the third connecting rope 410 is loosened, the friction end of the damping catch head 420 loses its tension and rotates downward under its own gravity. During rotation, the distance between the friction end and the fixed catch head 430 gradually decreases and clamps the belt, thereby preventing the belt from sliding further.

[0080] Through the above-described embodiments, the present application has the following beneficial effects or advantages: The conveyor belt breakage detection device disclosed in the present application adopts a damping capture method, utilizing the weight of the belt and material to reduce the downward force, thereby reducing the impact force on the belt and effectively avoiding secondary damage. Through the mechanical detection and capture device, automatic detection and capture of belt breakage is achieved, reducing the workload and labor intensity of manual maintenance, greatly improving the safety of conveyor equipment, and reducing the risk of accidents caused by belt breakage.
