Description

Technical Field

[0001] This utility model belongs to the technical field of tubular belt conveyors, and specifically relates to an abnormality detection device for the conveyor belt of a tubular belt conveyor. Background Technology

[0002] In the field of modern material handling, tubular belt conveyors, as a new type of conveying equipment, have demonstrated significant advantages due to their unique structural design and have become an important choice for material transportation in many industries. Their core feature is that materials can be completely sealed inside the cylindrical belt. This characteristic fundamentally solves the problems of dust and spillage that easily occur during material transportation with traditional conveyors, greatly improving the environmental performance of the conveying process and meeting the stringent requirements of current society for green production. At the same time, tubular belt conveyors have the advantage of long conveying distances, adapting to long-distance material transportation scenarios, reducing intermediate transfer links, and improving transportation efficiency.

[0003] Furthermore, its ability to be flexibly arranged along terrain curves makes it far more adaptable to complex terrain conditions than traditional conveyors. Whether in mountainous areas, hilly terrain, or urban building complexes, it can achieve efficient and stable material transport. Due to these outstanding advantages, tubular belt conveyors have been widely used in various industries such as mining, chemical, power, and building materials, playing an increasingly important role in optimizing production processes and reducing transportation costs. However, in actual production and operation, tubular belt conveyors are prone to various problems affecting their safe and stable operation due to the limitation of their tube diameter. If these problems are not effectively resolved, they will severely restrict their efficiency. Specifically, foreign objects longer than the tube diameter are easily punctured by the belt during the process of being wrapped by it; when a large flow of material enters the bag, it will cause the tube to expand, which will damage the belt and idlers. If these accidents are not detected and handled in time, they may cause serious failures such as large-area tearing and belt breakage of the tubular belt conveyor, which will not only lead to production interruption, but also cause huge economic losses and even endanger the safety of on-site operators.

[0004] To ensure the safe operation of tubular belt conveyors, existing technologies have implemented corresponding solutions to address the aforementioned issues. These include using variable frequency precise feeding to eliminate the impact of large material flows, employing iron removers to remove sharp iron debris, limiting large material flows before the conveyor belt forms a tube using limiting gates and switches, and adding multiple video monitoring systems to detect anomalies and promptly shut down the machine. While these safety measures have reduced the occurrence of belt tearing accidents to some extent, tubular belt conveyors still experience situations such as foreign object tearing and sudden large material flows causing tube expansion. Timely feedback is often impossible. When these anomalies occur, the lack of effective real-time detection methods prevents rapid warnings and appropriate interventions, leading to the continued development of the anomaly and potentially causing more serious equipment damage and production accidents. Therefore, there is an urgent need for a conveyor belt anomaly detection device for tubular belt conveyors. Utility Model Content

[0005] To address some or all of the technical problems existing in the prior art, this utility model provides a conveyor belt abnormality detection device for a tubular belt conveyor, comprising a vertical roller abutting against the outer periphery of the conveyor belt and a fixed base disposed below the vertical roller, wherein: A sleeve is hinged to the fixed base, and a connecting rod is connected between the sleeve and the vertical roller. One end of the connecting rod is fixedly connected to the bottom of the vertical roller, and the other end is hinged to the top of the sleeve. A swing arm is fixedly connected to the bottom of the sleeve, and a sensor module is provided below the swing arm. The sensor module is connected to a limit switch and an alarm module. A trigger rope is connected between the sensor module and the swing arm. The vertical roller is tilted at a preset angle to the horizontal plane.

[0006] Furthermore, in the above-mentioned abnormal detection device for the conveyor belt of the tubular belt conveyor, the trigger rope is a steel wire rope.

[0007] Furthermore, in the above-mentioned abnormal detection device for the conveyor belt of the tubular belt conveyor, an anti-slip layer is provided on the outer periphery of the vertical roller, and the anti-slip layer is made of rubber.

[0008] Furthermore, in the above-mentioned abnormal detection device for the conveyor belt of the tubular belt conveyor, the preset angle between the vertical roller and the horizontal plane is 85°~89°.

[0009] Furthermore, in the above-mentioned abnormal detection device for the conveyor belt of the tubular belt conveyor, the alarm module is connected to an indicator light.

[0010] Furthermore, in the above-mentioned abnormal detection device for the conveyor belt of the tubular belt conveyor, the alarm module is connected to a buzzer.

[0011] The conveyor belt anomaly detection device for the tubular belt conveyor of this utility model has the following advantages and beneficial effects: This device uses vertical rollers that abut against the outer periphery of the conveyor belt. When the conveyor belt experiences a large material flow or foreign object causing the tube diameter to expand, the vertical rollers will be subjected to radial force and become unstable. This will then cause the sleeve to rotate via a connecting rod, which will cause the swing arm to pull the trigger rope to trigger the sensor module, thereby triggering the limit switch and alarm module. This will allow the conveyor to stop running in time and issue an alarm, making it easier for personnel to handle the fault promptly. This effectively avoids serious equipment damage and production accidents caused by the continued development of abnormal situations, and ensures the safe and stable operation of the tubular belt conveyor.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0015] like Figure 1As shown, this utility model discloses a conveyor belt anomaly detection device for a tubular belt conveyor. The device includes a vertical roller 1 abutting against the outer periphery of the conveyor belt 100 and a fixed seat 4 disposed below the vertical roller 1. The main function of the vertical roller 1 is to sense changes in the state of the conveyor belt 100. A sleeve 3 is hinged to the fixed seat 4, and the sleeve 3 can rotate around the hinge point. A connecting rod 2 connects the sleeve 3 and the vertical roller 1. One end of the connecting rod 2 is fixedly connected to the bottom of the vertical roller 1, and the other end is hinged to the top of the sleeve 3. This connection method allows the movement of the vertical roller 1 to be transmitted to the sleeve 3 through the connecting rod 2. When the vertical roller 1 changes position, it will drive the connecting rod 3. The movement of rod 2 causes sleeve 3 to rotate around the hinge point on fixed seat 4. A swing arm 5 is fixedly connected to the bottom of sleeve 3. The swing arm 5 moves synchronously with the rotation of sleeve 3. A sensor module 7 is set below the swing arm 5. The sensor module 7 is connected to a limit switch 8 and an alarm module 9. The limit switch 8 is used to control the operating status of the tubular belt conveyor. When the sensor module 7 is triggered, the limit switch 8 is activated, which can stop the operation of the conveyor in time to prevent the abnormal situation from deteriorating further. The alarm module 9 is used to issue an alarm signal to remind the personnel that an abnormal situation has occurred. A trigger rope 6 is connected between the sensor module 7 and the swing arm 5. The vertical roller 1 is inclined at a preset angle to the horizontal plane.

[0016] As a specific implementation, in the conveyor belt abnormality detection device of the tubular belt conveyor of this utility model, the trigger rope 6 is made of steel wire rope. Steel wire rope has the characteristics of high strength, corrosion resistance and not easy to break, and can reliably transmit tension when the swing arm 5 moves, so as to ensure the triggering effect of the sensor module 7.

[0017] As a specific embodiment, in the conveyor belt abnormality detection device of the tubular belt conveyor of this utility model, the outer periphery of the vertical roller 1 is covered with an anti-slip layer. The anti-slip layer is made of rubber. The rubber material has good elasticity and anti-slip performance. On the one hand, it can increase the friction between the vertical roller 1 and the conveyor belt 100, ensuring that the vertical roller 1 can reliably follow the rotation of the conveyor belt 100 and avoid relative slippage that would affect the perception of the state of the conveyor belt 100. On the other hand, the rubber layer can also play a buffering role, reducing the wear caused to the surface of the conveyor belt 100 by the vertical roller 1 during the rotation with the conveyor belt 100, and protecting the conveyor belt 100.

[0018] In one specific embodiment, in the conveyor belt abnormality detection device of the tubular belt conveyor of this utility model, the preset angle between the vertical roller 1 and the horizontal plane is 85°~89°, more specifically, the preset angle between the vertical roller 1 and the horizontal plane is 87°. This angle setting allows the vertical roller 1 to stably abut against the outer periphery of the conveyor belt 100, and when the conveyor belt 100 experiences an abnormal situation of increased pipe diameter, it is easily subjected to radial force and becomes unstable. Of course, the specific preset angle needs to be set according to the working conditions in the actual use process.

[0019] In one specific embodiment, in the abnormal detection device of the tubular belt conveyor of this utility model, the alarm module 9 is connected to an indicator light. The indicator light can emit a conspicuous light signal, which can promptly remind the staff that the abnormality of the conveyor belt 100 has occurred, so that the staff can quickly arrive at the scene to check and handle it.

[0020] In one specific embodiment, in the conveyor belt abnormality detection device of the tubular belt conveyor of this utility model, the alarm module 9 is connected to a buzzer. The buzzer can emit a loud sound signal, which can promptly remind the staff that the conveyor belt 100 has an abnormality, so that the staff can quickly arrive at the scene to check and deal with it.

[0021] The working principle of the conveyor belt abnormality detection device for the tubular belt conveyor of this utility model is as follows: During normal operation of the tubular belt conveyor, the vertical roller 1 rotates along the connecting rod 2 as the conveyor belt 100 moves. At this time, the sleeve 3 and the swing arm 5 are relatively stationary, the trigger rope 6 is not under stress, the sensor module 7 is not triggered, and the limit switch 8 and alarm module 9 are both in normal condition, and the conveyor is operating normally. When a large flow of material or foreign objects enters the conveyor belt 100 or the belt opening, the diameter of the conveyor belt 100 will expand. When the expanded portion of the conveyor belt 100 passes the vertical roller 1, it will exert a radial force on the vertical roller 1, causing the nearly vertically installed vertical roller 1 to become unstable and fall to the other side. This, in turn, drives the connecting rod 2 to move, causing the sleeve 3 to rotate along the hinge point with the fixed seat 4. The rotation of 3 causes the swing arm 5 to move together. The swing arm 5 applies tension to the sensor module 7 by pulling the trigger rope 6, thereby triggering the sensor module 7. After the sensor module 7 is triggered, on the one hand, the limit switch 8 is activated to stop the operation of the conveyor, and on the other hand, the alarm module 9 is activated, the indicator light flashes, and the buzzer sounds to issue an alarm signal. After receiving the alarm signal, the staff goes to the site to check and eliminate the fault. After the accident is dealt with, the staff can reset the trigger rope 6 in the device to restore it to the normal position. At the same time, the limit switch 8 and other components are reset, and the device can be put into use again to continue to detect abnormal conditions of the conveyor belt 100.

[0022] In summary, compared with the prior art, the conveyor belt anomaly detection device for the tubular belt conveyor of this utility model has the following advantages and beneficial effects: This device uses a vertical roller 1 that rests against the outer periphery of the conveyor belt 100. When the diameter of the conveyor belt 100 expands due to a large material flow or foreign objects, the vertical roller 1 will be unstable due to radial force. This will cause the connecting rod 2 to drive the sleeve 3 to rotate, which will cause the swing arm 5 to pull the trigger rope 6 to trigger the sensor module 7, thereby triggering the limit switch 8 and the alarm module 9. This will stop the conveyor in time and issue an alarm, making it easier for personnel to handle the fault in a timely manner. This effectively avoids serious equipment damage and production accidents caused by the continued development of abnormal situations, and ensures the safe and stable operation of the tubular belt conveyor.
