[0002] Mining ore passes are tubular channels used in mining engineering for vertically or inclined transport of ore and waste rock, and are a crucial link in the mining transportation system. Mine pass inspection is a process of comprehensively examining and evaluating the internal structure, wear condition, and safety performance of the pass using technical means. Its aim is to ensure the safe operation of the pass, prevent accidents such as collapses, blockages, and spalling, and ensure both mine production efficiency and personnel safety.

[0003] Currently, existing detection devices for mine ore passes have some shortcomings. For example, it is difficult to flexibly adjust the detection angle during the detection process, resulting in a limited detection range and an inability to fully obtain information about the inside of the ore pass. At the same time, the stability and control precision of the detection device during the lifting and lowering process need to be improved, which affects the accuracy and reliability of the detection results.

[0004] Therefore, a mine chute shaft inspection device is proposed to address the above problems. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-5 As shown, a mine chute shaft inspection device includes a main body 1. A control and detection device 2 is provided on one side of the main body 1. The control and detection device 2 includes an angle adjustment component 3 and a rotation control component 4. The angle adjustment component 3 includes a mounting frame 21. A protective shell 24 is fixedly installed on the top of the mounting frame 21. A first servo motor 22 is installed on the back side of the protective shell 24. A first worm gear 23 is fixedly installed at the output end of the first servo motor 22. A first worm wheel 25 is meshed with the bottom of the first worm gear 23. The first worm wheel 25 passes through and is fixedly installed at one end of a rotating shaft 26. Two support blocks 27 are movably installed on the outer surface of the rotating shaft 26. The tops of the two support blocks 27 are fixedly installed at the bottom of the mounting frame 21. A connecting chamber 28 passes through and is fixedly installed on the rotating shaft 26.

[0025] During operation, the first servo motor 22 drives the first worm gear 23 at the output end to rotate. The meshing between the first worm gear 23 and the first worm wheel 25 transmits power to the rotation of the rotating shaft 26. When the rotating shaft 26 rotates, the support block 27 supports the rotating shaft 26 and performs corresponding limit movements to ensure the stability of the rotating shaft 26 driving the connecting chamber 28 to perform circumferential movements.

[0026] Furthermore, the main body 1 includes a torque motor 11 with a self-locking function, and a connecting shaft 13 is fixedly installed at the output end of the torque motor 11. A winch 14 is installed through the connecting shaft 13.

[0027] During operation, the drive torque motor 11 works, and the connecting shaft 13 at the conveying end drives the winch 14 to rotate, thereby using the winch 14 to drive the control and detection device 2 to perform lifting operations.

[0028] Furthermore, a motor base 12 is fixedly installed on the top of the torque motor 11, and two support seats 15 are installed through and movably mounted on the connecting shaft 13. A mounting bracket 21 is fixedly installed at the output end of the winch 14.

[0029] During operation, the motor base 12 and the support base 15 support the torque motor 11 and the connecting shaft 13 respectively, and ensure the limit situation during operation, so that the output end of the winch 14 can reliably drive the mounting frame 21 to move.

[0030] Furthermore, the rotation control component 4 includes a seal 29, a second servo motor 31 is fixedly installed on one side of the seal 29, a second worm gear 32 is fixedly installed on the output end of the second servo motor 31, and one side of the seal 29 is fixedly installed on one side of the connecting chamber 28.

[0031] During operation, the sealing element 29 is connected to one side of the connecting chamber 28. When the connecting chamber 28 rotates in a circular motion, it drives the sealing element 29 to rotate synchronously.

[0032] Furthermore, the rotation control component 4 also includes a second worm gear 33, which is installed through and fixedly mounted on the outer surface of the connecting shaft 34, and the back side of the second worm gear 33 is meshed with the second worm 32.

[0033] During operation, there is a self-locking property between the second worm 32 and the second worm wheel 33. When the lead angle of the second worm 32 is less than the equivalent friction angle between the meshing teeth, the mechanism has a self-locking property and can achieve reverse self-locking, that is, only the second worm 32 can drive the second worm wheel 33, and the second worm wheel 33 cannot drive the second worm 32.

[0034] Furthermore, the rotation control component 4 also includes a turntable 35, on the top of which a connecting shaft 34 is fixedly mounted, and a bearing 38 is movably mounted on the top of the connecting shaft 34. The outer surface of the bearing 38 is fixedly mounted to one side of the connecting chamber 28, and the turntable 35 is movably mounted on the bottom of the connecting chamber 28.

[0035] During operation, the connecting chamber 28 and the connecting shaft 34 are connected to each other through the installation of bearing 38. Under the action of bearing 38, the connecting shaft 34 can drive the turntable 35 to rotate inside the connecting chamber 28.

[0036] Furthermore, a camera 36 is fixedly installed at the bottom of the turntable 35, and an LED light 37 is fixedly installed on one side of the camera 36.

[0037] During operation, the camera 36 provides real-time illumination of the surrounding area of ​​the mine to detect and inspect for cracks or other abnormalities inside the mine. The camera 36 is battery-powered and uses wireless transmission. Since there is no light in the mine, LED lights 37 are used to supplement the lighting of the camera 36.

[0038] Working principle: When a depth inspection of a mine chute is required, the winch 14 is first driven by the torque motor 11 to rotate, lowering the control and inspection device 2 to the designated depth within the chute. During the descent, the self-locking function of the torque motor 11 ensures the stability of the winch 14, preventing the inspection device from suddenly sliding down. After reaching the designated depth, the first servo motor 22 is activated according to the inspection requirements. Through the transmission of the first worm gear 23 and the first worm wheel 25, the angle of the connecting chamber 28 is adjusted so that the turntable 35 and the camera 36 are aligned with the direction to be inspected. Then, the second servo motor 31 is activated. Through the transmission of the second worm gear 32 and the second worm wheel 33, the turntable 35 and the camera 36 are driven to rotate 360 ​​degrees, achieving all-round inspection of the chute at that depth. During the inspection, the LED light 37 provides illumination, and the image information captured by the camera 36 can be transmitted to the ground control terminal in real time for analysis by the operators. After the inspection is completed, the inspection device is lifted back to the ground by the torque motor 11, completing one inspection operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
