Description

Technical Field

[0001] This utility model relates to the field of tunnel surrounding rock deformation monitoring technology, and in particular to a tunnel surrounding rock deformation monitoring device based on a water-flooded environment. Background Technology

[0002] As the mining depth of coal and metal mines continues to increase, mine roadways face increasingly complex geological and hydrological conditions, especially in water-flooded environments, where the deformation and stability of the surrounding rock are particularly prominent. Water immersion causes softening, strength reduction, expansion deformation, and uncertainties in the mechanical properties of the surrounding rock, leading to a decrease in the bearing capacity of the support structure or even its failure, seriously threatening the safety and service life of the roadway. Furthermore, traditional surrounding rock monitoring and support methods are mostly designed for dry or unsaturated environments, lacking a deep understanding and effective response to the deformation characteristics of surrounding rock in water-flooded environments. Monitoring data accuracy is low, response speed is slow, and it is difficult to meet the stability requirements of roadways under complex hydrological conditions. Therefore, monitoring equipment is needed to monitor the deformation of the surrounding rock in roadways.

[0003] For example, a monitoring device for full-section deformation of surrounding rock in an underground roadway, with public announcement number CN220489982U, includes a roadway body, surrounding rock on the roadway body, and several anchor bolt bodies on the surrounding rock. One end of each anchor bolt body is connected to a monitoring mechanism, which is installed on one side of the surrounding rock. The monitoring mechanism includes a base, a main body, and a laser rangefinder body, with a laser emission port on the laser rangefinder body.

[0004] In summary, the following technical problems exist in the existing technology: Although the existing technology can monitor the deformation of the surrounding rock in the roadway, the monitoring mechanism needs to be fixed to the anchor rod one by one by tightening bolts with tools. Due to the large number of anchor rods, the installation of the monitoring operation is time-consuming and labor-intensive. Therefore, we propose a roadway surrounding rock deformation monitoring device based on a water-flooded environment. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] Example 1

[0028] Reference Figure 1-6 A roadway surrounding rock deformation monitoring device based on a flooded environment includes multiple anchor rods 2 evenly distributed and installed on the inner side of the roadway surrounding rock 1. One end of each anchor rod 2 penetrates the roadway surrounding rock 1 and is fixed with an anchor rod tray 3. A U-shaped equipment shell 4 is installed on the side of the anchor rod tray 3 away from the anchor rod 2. A monitoring mechanism is installed on the inner side of each U-shaped equipment shell 4. The monitoring mechanism is used to monitor the deformation of the roadway surrounding rock 1.

[0029] The monitoring mechanism includes a motor 5, a main body 6, a laser rangefinder 8, and a laser emitter 9. The motor 5 is fixed at one end of the U-shaped equipment shell 4. The model of the motor 5 is DS3230 digital rotary servo motor. The output end of the motor 5 passes through the U-shaped equipment shell 4 and is fixed to the main body 6. The laser rangefinder 8 is mounted at one end of the main body 6, and the laser emitter 9 is set at one end of the laser rangefinder 8. The monitoring mechanism also includes a rotary output shaft 7. A micro motor, model DS3230 digital rotary servo, is fixed inside the main body 6. The laser rangefinder 8 is a MyAntenna-L2s-40 laser rangefinder sensor. The output end of the micro motor passes through the main body 6 and is fixed to the rotary output shaft 7. One end of the rotary output shaft 7 is fixed to the laser rangefinder 8. During use, when the motor 5 is started, the output end of the motor 5 drives the main body 6 to rotate, thereby adjusting the angle of the laser rangefinder 8. When the micro motor is started, it drives the rotary output shaft 7 and the laser rangefinder 8 to rotate at multiple angles. This allows the position data of various points on the surface of the surrounding rock 1 in the underground roadway to be obtained through the polar coordinate axis system. The shape of the cross-section of the surrounding rock 1 in the roadway can be obtained through computer software processing. By combining the data measured at different times, dynamic monitoring of the deformation of the entire cross-section of the surrounding rock 1 in the underground roadway can be completed. This is a mature existing technology and will not be elaborated further here.

[0030] An extension rod 10 is fixed to the side of the anchor tray 3 away from the anchor rod 2. A fixed shell 11 is fixed to the top of the U-shaped equipment shell 4. A quick-connect mechanism is assembled between the fixed shell 11 and the extension rod 10. The quick-connect mechanism includes a positioning plate 12, a movable frame 13, a transmission cylinder 14, a lever 15, a handle 16, and a torsion spring 17. The positioning plate 12 is fixed to the inside of the fixed shell 11. The movable frame 13 is rotatably connected to the top of the positioning plate 12. The transmission cylinder 14 is fixed to the bottom of the movable frame 13. The transmission cylinder 14 is rotatably connected to the inside of the positioning plate 12. A torsion spring 17 is sleeved on the outside of the transmission cylinder 14. One end of the torsion spring 17 is fixed to the transmission cylinder 14, and the other end of the torsion spring 17 is fixed to the positioning plate 12. A lever 15 is fixed to one side of the frame 13. An arc-shaped through groove corresponding to the position of the lever 15 is opened on the outer side of the fixed shell 11. The arc-shaped through groove is slidably connected to the lever 15. Multiple pipa handles 16 are evenly distributed and rotatably connected to the inner side of the movable frame 13. The end of each pipa handle 16 away from the movable frame 13 is rotatably connected to the positioning plate 12 through a shaft. The arc-shaped through groove facilitates the user to pull the lever 15. At the same time, it can provide guidance and limit the path of the lever 15 when it rotates.

[0031] One end of the pipa handle 16 is integrally fixed with a cam part, which is rotatably connected to the movable frame 13 through a pin. The cam part and the pin form an eccentric movement, and the protruding end of the cam part is set close to the center of the movable frame 13.

[0032] Example 2

[0033] Further optimizations to Example 1, specifically, such as... Figure 6 As shown, the quick-connect mechanism also includes an arc-shaped protrusion 18. An arc-shaped protrusion 18 is fixed on the outer side of the cam portion. Multiple annular recesses are evenly distributed on the outer side of the extension rod 10. The annular recesses and the arc-shaped protrusion 18 are in transition fit. Through the fit between the arc-shaped protrusion 18 and the annular recesses, the friction between the arc-shaped protrusion 18 and the extension rod 10 can be increased, making the fixation of the extension rod 10 by the cam portion more stable.

[0034] In summary:

[0035] This utility model addresses the technical problem of existing technologies, which, while capable of monitoring deformation of the surrounding rock in tunnels, require individual bolt tightening of the monitoring mechanism onto anchor rods. Due to the large number of anchor rods, installation during monitoring is time-consuming and labor-intensive. The present invention employs the technical solutions described in the above embodiments. Furthermore, the implementation process of the above technical solutions is as follows:

[0036] All electrical components in this device are existing technologies, and their models are only one of them. Any electrical component that can achieve the purpose of this device can be used. Connect all electrical components in the device to their compatible power supply through wires. In addition, a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection between each electrical component should be completed in the order of operation. The detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and will not explain the electrical control.

[0037] During use, when the U-shaped equipment housing 4 needs to be installed, the lever 15 is turned, causing the lever 15 to drive the movable frame 13 and the transmission cylinder 14 to rotate. Because the cam part of the pipa handle 16 is rotatably connected to the movable frame 13 through a pin, and the end of the pipa handle 16 away from the cam part is rotatably connected to the positioning plate 12 through a shaft, when the lever 15 drives the movable frame 13 to rotate, the cam part can rotate eccentrically, thereby causing multiple pipa handles 16 to twist until multiple cam parts gradually release the obstruction of the center of the movable frame 13. Then, the extension rod 10 is inserted into the inside of the movable frame 13, and then the lever 15 is released. At this time, the torsional force generated by the torsion spring 17 drives the transmission cylinder 14 to reset and rotate, thereby causing multiple cam parts to drive the arc-shaped protrusion strip 18 to twist in the direction close to the extension rod 10, until multiple arc-shaped protrusion strips 18 clamp and fix the extension rod 10.

[0038] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects:

[0039] Through the structural design of the monitoring mechanism and the quick-connect mechanism, this utility model enables the device to monitor the deformation of the surrounding rock 1 in the roadway, and at the same time, it can also achieve quick installation between the U-shaped equipment shell 4 and the extension rod 10. This facilitates faster operation during the initial monitoring and allows for convenient disassembly and assembly in the later stages, thus improving the flexibility of the device and making it more convenient to use.
