Description

Technical Field

[0001] This utility model relates to the field of inspection equipment technology, and in particular to an inspection equipment for a tubular belt conveyor. Background Technology

[0002] In the coking industry, the application of electrical automatic control technology is becoming increasingly widespread. Among them, the application of electrical automatic control technology in pipe machinery systems has improved production efficiency and the production environment.

[0003] A tubular belt conveyor, also known as a tubular belt conveyor, is a device that uses a conveyor belt wound into a tubular shape to transport materials. It offers advantages such as long conveying distances, small footprint, and the ability to transport materials in curved areas. Because tubular belt conveyors typically operate in complex corridor environments, they are subjected to long-term friction, impact, and environmental factors. Components such as the conveyor belt, rollers, and bearings are prone to wear, loosening, and overheating. Failure to detect and address these issues promptly can lead to equipment downtime or even safety accidents.

[0004] Inspection is a crucial means of ensuring the safe and stable operation of tubular belt conveyors. Current inspection methods largely rely on manual labor, which is not only labor-intensive and inefficient, but also poses significant safety hazards and makes it difficult to achieve all-weather, high-precision monitoring. Some automated inspection equipment suffers from poor adaptability, and the angle and position adjustment of monitoring components are limited, making it difficult to comprehensively capture equipment operating status information, resulting in a low rate of fault identification.

[0005] Therefore, this utility model provides a tubular belt conveyor inspection device to better inspect and detect the operating status of the conveyor. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the prior art by proposing a tubular belt conveyor inspection device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: The tubular belt conveyor inspection equipment includes an inspection vehicle, which is equipped with a liftable mounting frame. An arc-shaped rail is rotatably mounted on the mounting frame, and a high-definition camera, an infrared thermal imager, and a sound pickup device are mounted on the rail.

[0008] Preferably, the mounting bracket has a mounting plate fixed at its end, and the mounting plate has multiple sets of guide structures. Each set of guide structures includes two spaced-apart guide wheels. The multiple sets of guide wheels are arranged along the arc-shaped rail frame. The inner and outer rings of the rail frame are provided with concave annular grooves. The two guide wheels of each set of guide structures are respectively embedded in the annular grooves on both sides.

[0009] Preferably, the rail frame is provided with a semi-circular arc gear, which meshes with a drive gear rotatably mounted on the mounting plate. The drive gear is driven by a drive motor fixed on the mounting plate.

[0010] Preferably, the end face of the arc-shaped gear is fixed with multiple brackets at intervals. Each bracket has a plane, a vertical plane, and a facet for mounting the high-definition camera, infrared thermal imager, and microphone. This ensures that the image-capturing and sound-receiving ends of the high-definition camera, infrared thermal imager, and microphone are perpendicular to the axis of the track frame.

[0011] Preferably, the guide wheel is wrapped with a rubber ring.

[0012] Preferably, the inspection vehicle is equipped with a turntable, on which an electric telescopic rod is fixed, and the extended end of the electric telescopic rod is fixedly connected to the mounting frame.

[0013] Compared with the prior art, this utility model provides an inspection device for a tubular belt conveyor, which has the following advantages: 1. This utility model utilizes a high-definition camera to capture real-time images of the conveyor belt surface and surrounding environment, clearly recording conveyor belt wear, loose joints, and other conditions; an infrared thermal imager continuously monitors the temperature of components such as rollers and bearings; and a sound pickup device collects the sound of the equipment during operation, capturing abnormal noises. These three monitoring data points complement and coordinate with each other, providing a more comprehensive reflection of the equipment's operating status. This enables multi-directional, high-precision inspection of the tubular belt conveyor, effectively improving inspection efficiency, reducing manual labor intensity and safety hazards, promptly detecting equipment faults and providing early warnings, and ensuring the safe and stable operation of the tubular belt conveyor. 2. Compared to manual inspections which require segment-by-segment checks and are time-consuming, this equipment can move quickly along the entire conveyor and perform multi-dimensional monitoring, significantly shortening the time for a single inspection. For key areas such as conveyor belt joints and roller connections, multi-angle key monitoring can be achieved through the rotation of the rail frame, improving inspection efficiency while reducing repetitive work.

[0014] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0024] The following will refer to the appendix in the embodiments of this utility model. Figure 1-8 The technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0025] Example 1: To address the problems existing in the prior art, this example provides a tubular belt conveyor inspection device, including an inspection vehicle 1. The inspection vehicle 1 is equipped with a turntable 2, which is a servo-driven single-axis turntable with only one rotating surface, driven by a servo motor to rotate 360°. An electric telescopic rod 3 is fixed on the turntable 2, and a mounting frame 4 is fixedly installed at the extended end of the electric telescopic rod 3. A mounting plate 5 is fixed to the end of the mounting frame 4, and the mounting plate 5 has multiple sets of guide structures. Each set of guide structures includes two spaced-apart guide wheels 6. The multiple guide structures are arranged at equal angles along an arc, forming two rows of inner and outer rings of guide wheels 6. An arc-shaped rail frame 7 is configured between the inner and outer rings of the rail frame 7. Both the inner and outer rings of the rail frame 7 have concave annular grooves, and the two guide wheels 6 of each set of guide structures are respectively embedded in the annular grooves on both sides. This structural design provides good guidance and limiting for the rotation of the rail frame 7, ensuring that the rail frame 7 rotates stably along a preset arc trajectory, avoiding deviation or shaking, and ensuring that the monitoring components are always aligned with the monitoring target. The track frame 7 is equipped with a semi-circular arc-shaped gear 8, which meshes with a drive gear 9 rotatably mounted on the mounting plate 5. The drive gear 9 is driven by a drive motor fixed on the mounting plate 5. The drive motor is a geared motor and can achieve self-locking. When the drive motor is working, it drives the drive gear 9 to rotate. Through the meshing transmission with the arc-shaped gear 8, the drive gear 9 drives the track frame 7 to rotate around its arc-shaped center, thereby realizing the angle adjustment of the monitoring components around the tubular belt conveyor, so as to monitor multiple axial parts of the tubular belt conveyor. Multiple brackets 13 are fixed at intervals on the end face of the arc-shaped gear 8. Each bracket 13 has a plane 131, a vertical plane 132, and a contour plane 133. A high-definition camera 10 is fixed to the plane 131 with screws; an infrared thermal imager 11 is fixed to the vertical plane 132 with bolts; and a microphone 12 is fixed to the contour plane 133 with bolts. The combination of the plane 131, vertical plane 132, and contour plane 133 aligns the image-capturing and sound-receiving components of the high-definition camera 10, infrared thermal imager 11, and microphone 12 with the vertical axis of the track 7, i.e., the vertical tubular belt conveyor. This installation method ensures that each monitoring component is always directly aligned with the tubular belt conveyor, improving the accuracy of data acquisition. The HD camera 10 features 1080P resolution and above, along with a wide-angle lens and autofocus, enabling it to clearly capture details such as conveyor belt surface wear, loose joints, and material spillage, as well as identify equipment appearance abnormalities, switch status, instrument readings, and indicator light colors. It is also equipped with an auxiliary light strip to support shooting in low-light environments, ensuring clear image acquisition even at night or in dimly lit corridors. The infrared thermal imager 11 can detect the surface temperature of key transmission components such as conveyor rollers and bearings in real time. By setting a temperature threshold, when the temperature of a component exceeds the threshold, it can quickly identify overheating abnormalities, provide timely warnings, and avoid failures caused by high component temperatures. The high-sensitivity sound pickup device 12 can accurately collect abnormal noises during the operation of the conveyor, such as friction noises caused by roller jamming and abnormal noises caused by bearing wear. It complements the images collected by the high-definition camera 10 and the temperature data collected by the infrared thermal imager 11, and comprehensively monitors the operating status of the equipment, improving the comprehensiveness and accuracy of fault identification. The mounting frame 4 is equipped with positioning elements, including but not limited to angle sensors, displacement sensors, and distance sensors. The angle sensors can monitor the rotation angle of the mounting frame 4 and the rail frame 7 in real time, the displacement sensors can detect the extension and retraction of the electric telescopic rod 3, and the distance sensors can measure the distance between the monitoring components and the tubular belt conveyor. Through the coordinated action of these positioning elements, the initial inspection position of the rail frame 7 and the tubular belt conveyor can be accurately matched, ensuring the accuracy and consistency of monitoring. In this embodiment, the guide wheel 6 is wrapped with a rubber ring made of elastic material. On the one hand, the rubber ring can increase the friction between the guide wheel 6 and the rail frame 7 to prevent slippage. On the other hand, it can play a buffering and shock-absorbing role, reducing the vibration of the rail frame 7 during rotation and ensuring the stability of the data collected by the monitoring component. At the same time, it also works with the self-locking property of the drive motor to enhance the locking effect when the rail frame 7 is stationary.

[0026] In this embodiment, the wrap angles of the rail frame 7 and the arc gear 8 are both no more than 180°, and their diameters are both larger than the external dimensions of the tubular belt conveyor, so as to facilitate the detection of displacement without interference.

[0027] In this embodiment, the inspection vehicle 1 is equipped with multiple cameras and radars around it to capture images of the environment from multiple angles, so as to obtain the real-time status of the inspection environment and use the background control to perform obstacle avoidance and other operations.

[0028] Based on the above technical solution: The inspection vehicle 1 conducts inspections along the conveyor corridor according to a predetermined trajectory. During the inspection, it obtains initial positioning data through the positioning element on the mounting frame 4, controls the rotation of the turntable 2 and the extension and retraction of the electric telescopic rod 3, so that the monitoring components on the rail frame 7 are aligned with the conveyor, and determines the initial monitoring angle and height. After initialization, the inspection equipment is activated, and inspection vehicle 1 begins to move along the side of the tubular belt conveyor under the command of the control system. Simultaneously, high-definition camera 10, infrared thermal imager 11, and audio pickup device 12 work together: high-definition camera 10 captures images of the conveyor surface; infrared thermal imager 11 scans components such as rollers and bearings in real time, transmitting temperature data to the backend system via Bluetooth; when the temperature exceeds a set threshold, the system immediately issues an overheat warning; audio pickup device 12 collects the operating sounds of the equipment, filters ambient noise, identifies abnormal sounds, and records them. All collected data is transmitted in real time to the remote monitoring center, allowing staff to view the conveyor's operating status in real time. When it is necessary to focus on monitoring specific areas of the conveyor (such as conveyor belt joints and roller connections), the control system controls the drive motor to start, and the drive gear 9 drives the arc gear 8 to rotate, so that the rail frame 7 rotates along the trajectory of the guide wheel 6, adjusts the angle of the monitoring components, and performs multi-angle shooting, temperature measurement and sound recording of the key area to ensure comprehensive capture of the operating status of the area. Similarly, at the same detection point, the axial circumferential detection of a single point on the conveyor can also be performed by adjusting the angle of the detection components.

[0029] When inspection vehicle 1 reaches the end of the conveyor, it completes one inspection task. It can then be controlled to return along the original path or wait at a preset stopping point for the next inspection instruction. Through the coordinated operation of all components of the machine, automated, all-round, and high-precision inspection of the tubular belt conveyor is achieved, greatly improving inspection efficiency and fault identification capabilities, and providing strong support for the safe and stable operation of the equipment.

[0030] When the testing vehicle is in a static standby state, the servo motor of the turntable 2 starts, driving the rail frame 7 to move above the testing vehicle, and the electric telescopic rod 3 is also in a retracted state, which reduces the space occupied by the equipment. By extending and retracting the electric telescopic rod 3, the mounting frame 4 can be raised and lowered, thereby adjusting the height of each monitoring component on the mounting frame 4 to adapt to the corridor laying state of the tubular belt conveyor; the turntable 2 can drive the mounting frame 4 and the monitoring components to rotate as a whole, which facilitates the adjustment of the monitoring direction and also enables the unfolding and storage of the testing components.

[0031] A high-definition camera 10 captures real-time images of the conveyor belt surface and surrounding environment, clearly recording conveyor belt wear, loose joints, and other issues. An infrared thermal imager 11 continuously monitors the temperature of components such as rollers and bearings. A sound pickup device 12 collects the sound of the equipment during operation, capturing abnormal noises. These three monitoring data complement and coordinate with each other, providing a more comprehensive reflection of the equipment's operating status. This enables multi-directional, high-precision inspection of the tubular belt conveyor, effectively improving inspection efficiency, reducing manual labor intensity and safety hazards, and promptly detecting and warning of equipment malfunctions, thus ensuring the safe and stable operation of the tubular belt conveyor. Preferably, a bracket can be installed at the output end of the electric telescopic rod 3, and another set of horizontal electric telescopic rods 3 can be configured on the bracket, with the extended end of the electric telescopic rod 3 connecting to the mounting frame 4. This allows for adjustment of the horizontal distance between the detection component and the detection vehicle. By adjusting the vertical and horizontal distance of the detection component through the two sets of electric telescopic rods 3, it is possible to better avoid the installation frame of the tube machine, and various operations are more flexible.
