Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining machinery and equipment technology, specifically to a device for detecting the operating status of a coal mine vertical shaft guideway. Background Technology
[0002] As a crucial component of the mine transportation system, the structural stability and operational status of mine guideways directly impact the overall production safety of the mine. Mine guideways not only undertake the task of transporting minerals but also play a guiding and supporting role in the mine's operation. Therefore, ensuring the reliability of guideways is of paramount importance to mine safety. The inspection of guideway operational status primarily focuses on whether there are defects such as cracks, weld defects, slag inclusions, or incomplete penetration at guideway joints or connections; whether bolt connections are loose, missing, corroded, or broken; and measuring the wear depth, width, and uniformity of the contact surface between the guideway and the guide lugs (or rollers).
[0003] Currently, the main methods for inspecting mine shaft guideways rely on regular manual inspections and timed checks. Manual inspections require personnel to go deep underground for visual and tapping inspections, which is not only inefficient and lacks accuracy, but also poses safety risks such as mine collapses and gas explosions. While timed checks can be conducted at certain intervals, they cannot detect sudden damage to the guideways in real time.
[0004] Therefore, this utility model proposes a device for detecting the operating status of a coal mine vertical shaft guideway. Utility Model Content

[0025] This invention proposes a device for detecting the operating status of a coal mine vertical shaft guideway. The device utilizes an industrial camera to photograph and inspect the wear condition of the roller guides. By detecting surface cracks and overall wear on the rubber rollers, it determines whether maintenance or replacement is necessary to ensure the safety and operational efficiency of the coal mine. In addition, this invention incorporates vibration and sound sensors to continuously detect the vibrations and sounds generated by the contact between the roller guides (or rollers) and the guideway. When defects or abnormal conditions exist in the guideway, its vibration characteristics and acoustic features will change significantly, thus determining an abnormal operating status. An alarm light is then used to promptly warn workers to conduct timely maintenance, ensuring safe mine operation. This invention, using an industrial camera and multiple sensors to detect the operating status of the guideway, significantly improves the accuracy and efficiency of detection, and provides more scientific and reliable data support for mine guideway status assessment and safety early warning.

This device can detect the operating status of the guideway, effectively improving detection efficiency and accuracy, and ensuring safe production operations in coal mines. The detection device mainly includes structural components such as a guide rail 1, a moving platform 2, a robotic arm 3, and an industrial camera 4.
[0045] Combination Figure 1 and Figure 2 As shown, the guide rail 1 is horizontally set at the bottom of the tank beam b. The moving platform 2 is slidably connected to the guide rail 1, and the moving platform 2 is equipped with a drive mechanism, which is used to drive the moving platform 2 to move laterally along the guide rail 1.
[0046] Combination Figures 7 to 9 As shown, the drive mechanism mainly includes structural components such as a drive motor 211, a first bevel gear 212, a second bevel gear 213, a first spur gear 214, a second spur gear 215, and a roller 216.
[0047] The cylinder end of the drive motor 211 is located inside the moving platform 2. The output end of the drive motor 211 is fixedly connected to the middle position of the first bevel gear 212, which meshes with the second bevel gear 213. The middle position of the second bevel gear 213 is connected to the middle position of the first spur gear 214 via a first connecting shaft. The first spur gear 214 meshes with the second spur gear 215, and the middle position of the second spur gear 215 is connected to the middle position of the roller 216 via a second connecting shaft. The roller 216 is connected to the guide rail 1. This detection device uses the drive motor 211 to provide power to rotate the roller 216, thereby enabling the moving platform 2 to move laterally along the guide rail 1.
[0048] Combination Figure 7 As shown, grooves are provided on both sides of the guide rail 1, and the cross-section of the guide rail 1 is I-shaped. The roller 216 is set in the groove. At the same time, auxiliary wheels 217 are symmetrically arranged on the moving platform 2, and the auxiliary wheels 217 are also set in the groove. The moving platform 2 moves laterally by means of the roller 216 and the auxiliary wheels 217.
[0049] Combination Figure 1 and Figure 2 As shown, limit stops 11 are provided at both ends of the guide rail 1 to prevent the moving platform 2 from moving excessively, avoid damage to its internal components, and extend the service life of the device.
[0050] Combination Figures 3 to 6 As shown, the mobile station 2 is equipped with an alarm light 6, which can provide timely warnings and is controlled by a host computer.
[0051] Combination Figures 3 to 6 As shown, an explosion-proof box 5 is installed at the bottom of the mobile station 2. Inside the explosion-proof box 5, a data acquisition box 51 and a sound sensor 53 are installed. The explosion-proof box 5 is made of high-strength alloy material, which can effectively prevent dust and moisture in the mine from entering. The data acquisition box 51 is used to collect the signals captured by the vibration sensor 52 and the sound sensor 53, and send these signals to the host computer to determine whether an abnormality has occurred and to issue an alarm.
[0052] The sound sensor 53 has its signal output terminal connected to the data acquisition box 51 via a data cable, and its detection terminal extends outside the explosion-proof box 5. The sound sensor 53 can detect abnormal sound frequencies and will issue an alarm when the sound frequency exceeds a threshold.

The vibration sensors 52 can detect abnormal vibration frequencies and will issue an alarm when the frequency exceeds a threshold.
[0053] When the cage / skip is running, the contact between the cage lugs (or rollers) and the cage will generate continuous vibration and sound. When there are defects or abnormal conditions in the cage, its vibration characteristics and acoustic features will change significantly.

Simultaneously, the robotic arm 3 is configured to flexibly adjust the shooting angle of the industrial camera 4, thereby improving the accuracy of the inspection and further ensuring the safety of the coal mine. The robotic arm includes two sets of swing motors and multiple swing arms. The swing motors can drive the swing arms to swing flexibly, thus flexibly adjusting the shooting angle of the industrial camera 4. Two sets of industrial cameras 4 are provided for supplementary shooting, preventing camera malfunctions from affecting the normal inspection process and increasing the redundancy of the inspection.
[0055] Combination Figure 4 As shown, supplementary lights 22 and vision sensors 23 are provided on both the front and rear sides of the mobile stage 2. The supplementary lights 22 can provide sufficient light and a good shooting environment for shooting, thereby improving the accuracy of detection.

This device utilizes an industrial camera 4 to photograph and inspect the wear condition of the roller guide rails. By detecting surface cracks and the degree of wear around the rollers, it determines whether maintenance or replacement is necessary, thus ensuring the safety and operational efficiency of the coal mine. This utility model's detection device combines the industrial camera 4 with a robotic arm 3, flexibly adjusting the shooting angle of the industrial camera 4 to complete the photographic inspection of the roller guide rails, effectively improving the accuracy of the photographic inspection. This invention's detection device continuously detects the vibration and sound generated by the contact between the can ear (or roller) and the can guide by adding a vibration sensor 52 and a sound sensor 53. When there are defects or abnormal conditions in the can guide, its vibration characteristics and acoustic features will change significantly, thereby determining that the can guide's operating status is abnormal. An early warning is issued in a timely manner through the alarm light 6, reminding the staff to carry out maintenance in time and ensuring the safe operation of the mine. This invention uses an industrial camera 4 and multiple sensors to detect the operating status of the can guide, which can significantly improve the detection accuracy and efficiency, and can provide more scientific and reliable data support for mine can guide status assessment and safety early warning.
