Description

Technical Field

[0001] This utility model relates to the field of coal conveyor belt inspection technology, and in particular to an intelligent coal conveyor belt inspection device. Background Technology

[0002] In industrial production, coal conveyor belts are core equipment for transporting bulk materials such as coal and ore, and their operating status directly affects production efficiency and safety. To ensure the stable operation of coal conveyor belts and promptly detect problems such as belt misalignment, tearing, and equipment malfunctions, intelligent inspection equipment has emerged. One type of intelligent coal conveyor belt inspection equipment achieves comprehensive, all-weather monitoring of the coal conveyor belt through automated movement and multi-sensor detection. This significantly reduces the labor intensity of manual inspections and improves the timeliness and accuracy of fault detection, making it an indispensable key piece of equipment in modern coal conveying systems.

[0003] In existing technologies, coal conveyor belt inspection equipment mostly adopts a track-type mobile structure. Its mechanical structure typically includes fixed tracks laid along both sides of the coal conveyor belt, a mobile vehicle carrying the detection device, and a simple drive system. Technically, movement is generally achieved through the friction between the drive wheels on the vehicle and the track surface, while fixed guide wheels on both sides of the vehicle limit lateral displacement to ensure the equipment runs along the track. The detection device is usually directly mounted on the vehicle and collects the operating data of the coal conveyor belt through components such as cameras and temperature sensors, transmitting the data to a backend for analysis and processing.

[0004] However, existing inspection equipment has significant shortcomings in practical applications. Due to the complex environment at coal conveying sites, the tracks experience wear and tear, installation errors, or slight deformation due to belt vibration after long-term use. The guide wheels of existing equipment are fixed in position and cannot be adjusted according to the track condition. Furthermore, the fit between the drive wheels and the track lacks an effective buffering and adjustment mechanism, making the equipment prone to deviation during operation due to uneven track or vibration, and even derailment or slippage. This severely affects the stability and reliability of inspections. Therefore, an intelligent inspection device for coal conveying belts is proposed to address these problems. Utility Model Content

[0036] Example 1: An intelligent inspection device for coal conveyor belts, referring to... Figures 1-5 This utility model provides an embodiment of an intelligent inspection device for a coal conveyor belt, comprising a circular track 1. The track adopts a segmented splicing structure for easy installation and maintenance. The circular track 1 provides a closed-loop inspection path for the device, achieving full coverage of the coal conveyor belt. A dust collection trough is provided at the bottom of the circular track 1 to reduce the impact of dust on the transmission components. A vehicle body 2 is provided on the side wall of the circular track 1. The vehicle body 2 is used to carry various functional components, serving as a load-bearing and connecting component. A robotic arm 11 is rotatably connected to the bottom of the vehicle body 2. The robotic arm 11 adopts an articulated structure and can automatically expand or contract according to the width of the belt. A protective cover 12 is rotatably connected to one end of the robotic arm 11. The protective cover 12 is used to protect the internal sensors from interference from dust, coal slag, and other debris, serving a protective function. An adaptive component is provided on the side wall of the vehicle body 2 to ensure the stable operation of the vehicle body 2 on the circular track 1 and improve the device's ability to adapt to complex working conditions. A cleaning component is provided on the upper surface of the protective cover 12 to remove dust from the surface of the transparent screen 24, ensuring the clarity of sensor detection.

[0037] The adaptive component includes a guide wheel 5 and a drive wheel 6. The guide wheel 5 limits the lateral displacement of the vehicle body 2, preventing it from shifting laterally along the track. The guide wheel 5 is slidably connected to the inside of the vehicle body 2. The drive wheel 6 is located above the vehicle body 2 and is covered with an anti-slip rubber layer. The drive wheel 6 contacts the bottom of the circular track 1 and, together with the drive gear 4, provides auxiliary support and friction to the vehicle body 2, enhancing operational stability. An adjusting screw 9 is rotatably connected inside the vehicle body 2. A slider 10 is threadedly connected to the side wall of the adjusting screw 9. The slider 10 transmits the rotational motion of the adjusting screw 9 as linear motion, driving... The guide wheel 5 moves laterally. The slider 10 is fixedly connected to the side wall of the guide wheel 5. The bottom of the drive wheel 6 is fixedly connected to the damper 7. The damper 7 is used to suppress the reciprocating vibration of the spring 8 and prevent the car body 2 from bumping due to vibration. One end of the damper 7 is fixedly connected to the top of the car body 2. The bottom of the drive wheel 6 is provided with a spring 8. The spring 8 is used to absorb the impact force generated by uneven track or vibration through elastic deformation, and plays a buffering role. One end of the spring 8 is fixedly connected to the bottom of the drive wheel 6, and the other end of the spring 8 is fixedly connected to the top of the car body 2. Through the above structure, the effect of adaptive belt support height change can be achieved.

[0038] The protective cover 12 is equipped with an infrared thermal imager 13, which is used to detect abnormal temperatures of the coal conveyor belt and surrounding equipment, and to detect overheating faults in a timely manner. The protective cover 12 is also equipped with a laser rangefinder 14, which is used to measure the distance to the surface of the coal conveyor belt, and to determine whether the belt is misaligned or has abnormal thickness. The protective cover 12 is also equipped with a vibration sensor 15, which is used to collect vibration signals from the surrounding equipment of the coal conveyor belt, and to identify whether the equipment has faults such as bearing wear or loosening. The protective cover 12 is rotatably connected to a door panel 23, which is used to facilitate the inspection and maintenance of the sensors inside the protective cover 12, and to improve the convenience of equipment maintenance.

[0039] A toothed belt 3 is installed inside the circular track 1, and a drive gear 4 is installed on the upper surface of the car body 2. The drive gear 4 is used to mesh with the toothed belt 3 to transmit power to the car body 2, thereby moving the car body 2 along the circular track 1. The meshing of the drive gear 4 and the toothed belt 3 provides stable driving force for the car body 2 and prevents slippage. The guide wheel 5 is slidably connected to the side wall of the circular track 1. The guide wheel 5 slides with the side wall of the circular track 1 to limit the lateral displacement of the car body 2 and ensure that the car body 2 runs along the track direction. The drive wheel 6 is slidably connected to the bottom of the circular track 1. The drive wheel 6 slides with the bottom of the circular track 1 to provide support for the car body 2 and enhances the running stability in conjunction with the drive gear 4.

[0040] The vehicle body 2 obtains power through a contact-type sliding contact line to avoid cable dragging; data transmission adopts a wireless mesh network, and repeaters are set at the track nodes to ensure stable signal transmission; the equipment is equipped with a backup battery to maintain emergency inspection function in the event of a main power failure.

[0041] Example 2: An intelligent inspection device for coal conveyor belts, referring to... Figures 6-7 The cleaning component includes a cleaning roller 22, which is used to remove dust from the surface of the transparent screen 24 to ensure the light transmittance of the transparent screen 24. The side wall of the cleaning roller 22 is in contact with the side wall of the transparent screen 24. The cleaning roller 22 and the transparent screen 24 slide and rub against each other to achieve efficient dust removal and avoid dust obstruction affecting the sensor detection effect. A motor 16 is fixedly connected inside the protective cover 12. The motor 16 is used to provide power to drive the cleaning component to operate. A crank wheel 17 is fixedly connected to the output end of the motor 16. The crank wheel 17 is used to convert the rotational motion of the motor 16 into the reciprocating motion of the rotating bar 18, which plays the role of power transmission and motion conversion. The top of the protective cover 12 is rotatably connected to the rotating bar 18. The rotating bar 18 is used to transmit the power of the crank wheel 17 to the connecting block 21, which drives the connecting block 21 to slide. The side wall of the rotating bar 18 is slidably connected to the side wall of the crank wheel 17. The rotating bar 18 slides and rotates in cooperation with the crank wheel 17, which achieves the effect of smoothly converting the rotational motion into reciprocating linear motion.

[0042] A fixing frame 19 is fixedly connected to the upper surface of the protective cover 12. The fixing frame 19 is used to fix and support the fixing rod 20, ensuring the stability of the sliding path of the connecting block 21. The fixing rod 20 is fixedly connected between the fixing frames 19. The fixing rod 20 is used to provide a sliding track for the connecting block 21 and restrict the movement direction of the connecting block 21. The connecting block 21 is slidably connected to the side wall of the fixing rod 20. The connecting block 21 is used to connect the rotating bar 18 and the cleaning roller 22, transmitting power and driving the cleaning roller 22 to move. One end of the cleaning roller 22 is fixedly connected to the side wall of the connecting block 21. The connecting block 21 cooperates with the cleaning roller 22 to slide synchronously, achieving the effect of driving the cleaning roller 22 to move stably along the transparent screen 24. One end of the rotating bar 18 is rotatably connected to the side wall of the connecting block 21. The rotating bar 18 cooperates with the connecting block 21 to rotate and push, achieving the effect of efficiently transmitting power and ensuring the smooth reciprocating motion of the cleaning roller 22.

[0043] Working Principle: When using this equipment, the circular track 1 is laid along both sides of the coal conveyor belt. The toothed belt 3 inside it meshes with the drive gear 4 on the upper surface of the car body 2. When the drive gear 4 rotates, it drives the car body 2 to move back and forth along the circular track 1 through the meshing transmission with the toothed belt 3, achieving full inspection coverage of the coal conveyor belt. When the adjusting screw 9 inside the car body 2 rotates, it drives the threaded slider 10 to move laterally, thereby adjusting the position of the guide wheel 5. The side wall of the guide wheel 5 is slidably connected to the side wall of the circular track 1. The position adjustment ensures the fit between the car body 2 and the track, preventing derailment during operation. The spring 8 and damper 7 at the bottom of the drive wheel 6 work together. The spring 8 absorbs the impact caused by uneven track or belt vibration through elastic deformation, while the damper 7 suppresses the reciprocating vibration of the spring 8, so that the drive wheel 6 always keeps stably in contact with the bottom of the circular track 1, avoiding slippage. The mechanical arm 11 at the bottom of the car body 2 can rotate flexibly. The mechanical arm 11 adopts an articulated structure and can automatically extend or retract according to the width of the belt. The system is designed to ensure optimal detection distance between the sensor and the belt. A protective cover 12 at the end of the cover provides protection for the sensor. An infrared thermal imager 13 inside the cover 12 detects abnormal temperatures in the belt and surrounding equipment, such as overheating of the idler rollers. A laser rangefinder 14 measures the distance to the belt surface in real time to determine belt misalignment or thickness changes. A vibration sensor 15 collects vibration signals from the idler rollers, motor 16, and other equipment to identify mechanical faults. A transparent screen 24 on the side wall of the cover 12 provides a detection window for the sensor. The door panel 23 on the side wall can be opened for easy sensor maintenance. To prevent dust accumulation on the transparent screen 24 from affecting detection, a cleaning component on the cover 12 operates automatically. The motor 16 drives the crank wheel 17 to rotate. Through the sliding connection between the crank wheel 17 and the rotating bar 18, the rotating bar 18 reciprocates. The rotating bar 18 pushes the connecting block 21 to slide laterally along the fixed rod 20 between the fixed frames 19, causing the cleaning roller 22 on the side wall of the connecting block 21 to reciprocate against the side wall of the transparent screen 24, removing surface dust.

[0044] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
