Technical Field

[0001] This utility model relates to the field of conveyor belt detection technology, and in particular to a device for monitoring tearing and surface damage of steel wire rope core conveyor belts for mining belt conveyors. Background Technology

[0002] In the mining industry, mining belt conveyors are key equipment for material transportation, and the operating status of their steel cord conveyor belts directly affects production efficiency and safety. Because conveyor belts are prone to tearing, surface damage, and internal steel wire breakage and delamination during long-term operation, real-time and accurate detection is crucial.

[0003] Traditional testing equipment is difficult to adjust flexibly according to different installation heights of mining conveyor belts, resulting in an inability to adapt to diverse on-site working conditions and limiting the application range of the equipment. In terms of angle adaptation, when the mining conveyor belt is set at an angle, existing equipment lacks an effective angle adjustment mechanism, making it impossible to keep the testing components parallel to the inclined conveyor belt, thus affecting the accuracy and comprehensiveness of the testing. To solve the above problems, this application proposes a monitoring device for tearing and belt surface damage of steel wire rope core conveyor belts for mining belt conveyors. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3A monitoring device for tearing and surface damage of steel wire rope core conveyor belts in mining applications includes a base 1. Four support legs are fixedly connected to the bottom of the base 1, each with a locking caster wheel for easy movement and fixation. A hollow column 2 is fixedly connected to the top of the base 1. A sliding column 3 is slidably connected to the top of the hollow column 2. A lifting mechanism is provided between the hollow column 2 and the sliding column 3. The lifting mechanism includes a first worm gear 7 that passes through and rotatably connects to the hollow column 2. A first handle 8 is fixedly connected to the end of the first worm gear 7 away from the hollow column 2 for easy operation. The first worm gear 7 meshes with a first worm wheel 9. A first threaded rod 10 is rotatably connected to the first worm wheel 9, coaxially. The bottom of the first threaded rod 10 is rotatably connected to the top of the base 1. The first threaded rod 10 is threadedly connected to the sliding column 3, causing the sliding column 3 to rise and fall via threaded transmission. An anti-detachment block is fixedly connected to the bottom outer wall of the sliding column 3, located inside the hollow column 2 and slidably connected to it, preventing the sliding column 3 from detaching from the hollow column 2.

[0020] A hollow box 4 is fixedly connected to the top of the sliding column 3. A display panel 11 is fixedly connected to the side wall of the hollow box 4 for displaying the detected data. A fixing frame 5 is provided on the side of the hollow box 4 away from the display panel 11. A rotating mechanism is provided between the hollow box 4 and the fixing frame 5. The rotating mechanism includes a second worm gear 14 that passes through the hollow box 4 and is rotatably connected to it. A second handle 15 is fixedly connected to the top of the second worm gear 14. The second worm gear 14 is engaged with a second worm wheel 13. A rotating rod 12 is fixedly connected to the second worm wheel 13 on the same axis. The rotating rod 12 passes through the hollow box 4 and is rotatably connected to it. The end of the rotating rod 12 away from the hollow box 4 is fixedly connected to the side wall of the fixing frame 5. The self-locking property of the worm wheel and worm gear ensures the stability of the rotating rod 12 after rotation.

[0021] Two movable plates 6 are provided on the side of the fixed frame 5 away from the hollow box 4. The fixed frame 5 is provided with an adjustment mechanism, which includes a lead screw 16 that passes through the fixed frame 5 and is rotatably connected to it. Rotating the lead screw 16 can adjust the position of the movable plates 6. A handle 17 is fixedly connected to the top of the lead screw 16. The lead screw 16 passes through the two movable plates 6 and is threadedly connected to them. The lead screw 16 is provided with two external threads with opposite directions. The two movable plates 6 are respectively fitted on the two external threads with opposite directions. The relative or opposite movement of the movable plates 6 is realized by the reverse threads. Two sliding rods are fixedly connected to the inner wall of the fixed frame 5. Both sliding rods pass through the two movable plates 6 and are slidably connected to them to guide and limit the movement of the movable plates 6.

[0022] Cameras 18 are fixedly connected to the opposite ends of the two movable plates 6 for video monitoring of the mining conveyor belt 20 and for detecting and monitoring belt surface damage and tearing. Two ultrasonic flaw detectors 19 are fixedly connected to the opposite ends of the two movable plates 6 for transmitting and receiving ultrasonic waves to analyze changes in the internal structure of the mining conveyor belt 20 and to detect the steel wire rope core of the conveyor belt. The mining conveyor belt 20 is provided on one side of the fixed frame 5.

[0023] In this invention, when it is necessary to inspect the conveyor belt 20, the operator pushes the device to one side of the conveyor belt 20. Depending on the height of the conveyor belt 20, the operator can hold the first handle 8 and rotate it, causing the first worm gear 7, the first handle 8, and the first threaded rod 10 to rotate. This causes the sliding column 3 to slide on the hollow column 2, thereby causing the hollow box 4, display panel 11, fixing frame 5, and two moving plates 6 to move up and down, positioning the lower layer of the conveyor belt 20 between the two moving plates 6. The operator then holds the handle 17 and rotates it, causing the lead screw 16 to rotate, causing the moving plates 6 on both sides, the camera 18, and the ultrasonic flaw detector 19 to move relative to each other. This allows for adjustment of the camera 18, the ultrasonic flaw detector 19, and... The spacing between the mining conveyor belts 20 can be monitored by camera 18, and ultrasonic waves can be emitted onto the mining conveyor belts 20 by ultrasonic flaw detector 19. By receiving the reflected ultrasonic waves, internal structural changes (such as delamination or wire breakage) can be analyzed. The operator holds the second handle 15 and rotates it to drive the second worm gear 14, the second worm wheel 13, the rotating rod 12, the fixed frame 5, and the two moving plates 6 to rotate around the rotating rod 12 as the rotation center, thereby adjusting the angle of the two moving plates 6. When the mining conveyor belts 20 are tilted, the angle of the two mining conveyor belts 20 can be adjusted according to the tilt angle of the mining conveyor belts 20, so that the two moving plates 6 are parallel to the tilted mining conveyor belts 20 to meet different usage needs.
