[0016] Combination Figures 1 to 8 As shown, this utility model proposes a roadway surrounding rock deformation monitoring device, which can monitor the deformation of the surrounding rock in the roadway to ensure safe production in coal mines. The device mainly includes structural components such as a base 1, a support column 2, a roof plate 3, a drive mechanism, an electric push rod 4, a laser rangefinder 61, and a panoramic camera 62.

[0017] Combination Figures 1 to 3 As shown, base 1 is the supporting foundation of the entire device. It is made of high-strength alloy steel and has good compressive and deformation resistance, ensuring that the structure remains stable under long-term pressure and the weight of the equipment, thus guaranteeing the accuracy of the monitoring results.

[0018] Combination Figures 1 to 3As shown, support feet 11 are located at the corners of the base 1. The bottom of each support foot 11 has anti-slip protrusions. This design significantly enhances the friction between the device and the roadway floor, effectively preventing the equipment from sliding or shifting due to external forces during monitoring, thus ensuring the accuracy and continuity of the monitoring data. Simultaneously, multiple casters are also provided at the bottom of the base 1. This design allows the device to be easily moved when monitoring points need to be relocated, greatly improving the flexibility and efficiency of the monitoring work.

[0019] Combination Figure 1 As shown, the support column 2 is vertically positioned at the center of the base 1. As a key component connecting the base 1 and the top plate 3, it is made of high-strength steel pipe and has excellent load-bearing capacity and stability. The top of the support column 2 is fixedly connected to the top plate 3, providing a stable support frame for the entire device.

[0020] Combination Figure 2 and Figure 3 As shown, the top plate 3 serves as the upper structure of the device, supporting key monitoring equipment such as the electric push rod 5, the laser rangefinder 61, and the panoramic camera 62. The top plate 3 is made of lightweight, high-strength materials, which ensures the stability of the structure while reducing the overall weight of the device, facilitating transportation and installation.

[0021] Combination Figure 1 As shown, a rotating disk 46 that can rotate relative to the top plate 3 is provided above the top plate 3. An electric push rod 5 is provided on the top of the rotating disk 46. This design enables the monitoring equipment to rotate 360° in the horizontal direction, thereby realizing all-round monitoring of the surrounding rock area.

[0022] Combination Figure 4 As shown, the rotating disk 46 is equipped with a drive mechanism that enables the rotating disk 46 to rotate relative to the top plate 3. The drive mechanism mainly includes a drive motor 41, a drive wheel 42, a transmission belt 43, a driven wheel 44, and a rotating connecting shaft 45. The cylinder end of the drive motor 41 is fixedly connected to the bottom of the top plate 3, and the output end of the drive motor 41 is connected to the middle position of the drive wheel 42. The drive wheel 42 is connected to the driven wheel 44 via the transmission belt 43, and the middle position of the driven wheel 44 is connected to the bottom end of the rotating connecting shaft 45. The rotating connecting shaft 45 is vertically arranged, and its top end extends out of the top plate 3 and is fixedly connected to the middle position of the rotating disk 46. The monitoring device of this utility model uses the drive motor 41 to provide power to drive the drive wheel 42 to rotate, and the transmission belt 43 drives the driven wheel 44 to rotate, thereby driving the rotating connecting shaft 45 and the rotating disk 46 to rotate synchronously. This transmission system has a compact design and high transmission efficiency, ensuring the stability and accuracy of the rotating disk 46 during rotation.

[0023] Combination Figure 4As shown, the drive pulley 42, transmission belt 43, and driven pulley 44 are all housed inside the top plate 3. This built-in design not only optimizes the overall structure of the device, making it more compact and aesthetically pleasing, but also effectively protects the transmission components from the harsh environment of dust and moisture in the tunnel, thereby extending the service life of the equipment and reducing maintenance costs. Simultaneously, sufficient space is reserved inside the top plate 3 for heat dissipation, ensuring that the drive motor 41 maintains good working condition during long-term operation and preventing performance degradation or malfunction due to overheating.

[0024] Combination Figures 5 to 7 As shown, the bottom of the cylinder end of the electric push rod 5 is fixedly connected to the top of the rotating disk 46. Supports 52 are arranged opposite each other on both sides of the top of the cylinder end of the electric push rod 5, and the two supports 52 are connected by a rotating shaft with a gear 53 mounted on it. A rack is provided on one side of the telescopic rod 51 of the electric push rod 5, and the gear 53 meshes with the rack to form a rack and pinion transmission structure. When the telescopic rod 51 of the electric push rod 5 extends or retracts, the rack moves synchronously, thereby driving the gear 53 to rotate, achieving flexible adjustment of the monitoring angle. Furthermore, the drive mechanism drives the rotating disk 46 to rotate, enabling multi-angle laser ranging and panoramic imaging of the surrounding rock in the tunnel, thus obtaining more comprehensive and accurate data on the deformation of the surrounding rock. This design allows the monitoring device to dynamically adjust the position and angle of the laser rangefinder 61 and the panoramic camera 62 according to the actual deformation of different tunnels, ensuring no blind spots in monitoring and greatly improving the accuracy and reliability of the monitoring.

[0025] Combination Figure 5 As shown, a laser rangefinder 61 and a panoramic camera 62 are connected to one side of the gear 53 via a fixing plate 60. The laser rangefinder 61 can accurately measure the distance change from the surrounding rock surface to the monitoring point, providing crucial data for analyzing surrounding rock deformation. The panoramic camera 62 can capture real-time images of the surrounding rock, intuitively reflecting the deformation trend and crack propagation, providing a direct basis for mine safety decisions.

[0026] In addition, combined Figure 2 and Figure 3 As shown, a warning light 72 and a controller 71 are also installed on the top of the top plate 3. The warning light 72 can immediately trigger an audible and visual alarm when abnormal deformation is detected, reminding staff to take timely countermeasures. The controller 71, as the control center of the device, is connected to the control terminals of the warning light 72, drive motor 41, electric push rod 5, laser rangefinder 61, and panoramic camera 62 via data cables, realizing automated control and data recording and analysis of the entire monitoring process.

[0027] In summary, this utility model proposes a tunnel surrounding rock deformation monitoring device that achieves comprehensive, dynamic, and precise monitoring of tunnel surrounding rock deformation. In practical applications, the laser rangefinder 61 and the panoramic camera 62 work together to acquire real-time distance changes and deformation images of the surrounding rock surface, providing detailed and reliable data support for analyzing surrounding rock stability. The cooperation between the drive mechanism and the electric push rod 5 allows the monitoring device to flexibly adjust the monitoring position and angle, effectively covering different tunnel cross-sections and avoiding monitoring blind spots. Simultaneously, the integrated application of the warning light 72 and the controller 71 further enhances the device's safety and intelligence, enabling timely alarms when abnormal deformation is detected, and recording data and analyzing deformation rates through the controller 71, providing a scientific basis for mine safety decisions. Furthermore, the support feet 11, the anti-slip protrusions, and the bottom rollers enhance the device's stability and mobility in complex tunnel environments, significantly improving monitoring efficiency and applicability.
