Description

Technical Field

[0001] This utility model relates to the field of advanced detection during coal mine excavation and exploration, specifically a convenient mobile device for advanced detection during coal mine excavation and exploration. Background Technology

[0002] As coal mining progresses towards deeper and more complex geological conditions, traditional seismic exploration techniques face new challenges. Traditional seismic exploration typically relies on explosive sources, which not only requires halting tunneling operations but also carries significant safety risks and low efficiency. Furthermore, the low vibration frequency of explosive sources makes it difficult to achieve precise detection of complex geological structures.

[0003] In recent years, seismic wave advance detection technology based on the noise source of tunnel boring machine (TBM) rock breaking has gradually attracted attention as an emerging exploration method. This method uses the vibration generated when the TBM cuts the rock as the source, without the need for an additional excitation device, and can conduct geological exploration in real time during normal tunneling. Although this technology has high efficiency and safety, the existing equipment layout and sensor installation methods have some shortcomings, namely: cumbersome sensor layout, time-consuming equipment movement and reinstallation, and unreasonable use of space in the tunnel, which limit the application effect of the on-demand exploration technology. Therefore, in order to address the above problems, a convenient mobile device for mine on-demand exploration advance detection is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as cumbersome sensor placement, time-consuming equipment relocation and reinstallation, and unreasonable utilization of space within tunnels, which limit the application effectiveness of on-demand exploration technology, this utility model proposes a convenient and easily movable on-demand exploration advanced detection device for mining.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a convenient moving device for advance detection in mining while excavating, including an overall structure of the convenient moving device. The overall structure of the convenient moving device includes an anchor rod and a special anchor rod long nut. The anchor rod and the special anchor rod long nut are threaded together. The side of the special anchor rod long nut is provided with a Y-direction fixing device, an X-direction fixing device and a Z-direction fixing device. The top of the special anchor rod long nut is provided with a roller. The roller track is installed on the side wall of the roadway. The anchor rod is movably connected to the roadway wall. An acceleration sensor body is installed at the end of the Y-direction fixing device, the X-direction fixing device and the Z-direction fixing device away from the special anchor rod long nut. Multiple overall structures of the convenient moving device are electrically connected through sensor data connection lines. A wire take-up assembly is installed in the middle of the sensor data connection lines.

[0006] Preferably, each of the multiple accelerometer bodies has a sensor tail cone at one end near the long nut of the special anchor rod. The ends of the multiple sensor tail cones away from the accelerometer bodies are fixedly connected to coupling bayonets. The multiple coupling bayonets are threadedly connected to the Y-direction fixing device, the X-direction fixing device, and the Z-direction fixing device, respectively. A data transmission module is provided on the side of the accelerometer body away from the sensor tail cone. A cover plate is fixedly connected to the side of the data transmission module away from the sensor tail cone. A level is installed on the side of the cover plate. The data transmission module is telecommunicationly connected to the overall architecture of the convenient moving device via a data transmission line.

[0007] Preferably, the cable take-up assembly includes an upper cover, a lower cover fixedly connected to the lower end of the upper cover, a fixing post fixedly connected to the middle of the lower cover, a limiting post fixedly connected to the side of the fixing post, and a torsion spring provided in the middle of the lower cover, one side of the torsion spring engaging with the limiting post and the other side engaging with the sensor data connection line.

[0008] Preferably, the lower cover is provided with two inner cable outlet slots that match the sensor data connection lines, and the inner cable outlet slots are in a skewed "Z" shape.

[0009] Preferably, the upper cover has an external cable channel that matches the sensor data connection line and the internal cable channel.

[0010] Preferably, a motor is mounted on the side of the roller away from the long nut of the special anchor bolt.

[0011] The advantages of this utility model are:

[0012] 1. This utility model comprises a convenient moving device overall structure, anchor bolts, special anchor bolt long nuts, rollers, Y-direction fixing devices, X-direction fixing devices, Z-direction fixing devices, and a motor. The convenient moving device overall structure is made of lightweight, high-strength materials to ensure sufficient durability and stability during tunneling. The anchor bolts and special anchor bolt long nuts are threaded together, enabling rigid connection with anchor bolts already coupled to the tunnel wall, ensuring good signal quality. The rollers' slide rails are arranged along the sidewall of the tunnel wall, supporting smooth movement of the device within the tunnel. The accelerometer sensor main body fixing device is designed for Y-direction fixing. The device features a three-directional modular structure consisting of an X-axis fixing device and a Z-axis fixing device. This allows the accelerometer to acquire signals from three directions. The rollers move along the slide rails, and the control system is integrated into the overall architecture of the easy-to-move device. The speed and direction of the motor and rollers can be controlled remotely. The device is equipped with a wireless data transmission module, which can transmit the acquired seismic data to the ground server in real time. The key to the design of this device lies in its convenience and efficiency. Through modular design and rapid installation, the equipment can be flexibly moved and adjusted as the tunneling machine advances, ensuring the continuity and accuracy of the detection process.

[0013] 2. This utility model, through the connection structure design of the cable winding assembly, addresses the issue that during installation, the sensor data connection cable is often long and is typically placed in an arc shape on the wall. Workers, machinery, or debris from such machinery may strike the cable, potentially breaking it. In this case, the sensor data connection cable is passed through the upper and lower covers and secured to the torsion spring. As the torsion spring winds up, both the inlet and outlet ends wind up simultaneously, entering along the upper and lower ends of the inner cable outlet groove. This prevents the sensor data connection cables on both sides of the upper cover from being squeezed together. The spring's elasticity causes the cable to rotate inward, retracting the long cable within the upper and lower covers, preventing workers from tripping and causing short circuits.

[0021] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0022] This application discloses a convenient mobile device for on-demand exploration and advanced detection in mining. (Refer to...) Figure 1 and Figure 2 A convenient mobile device for advanced detection in mining while excavating and exploring, comprising a general structure 14, including an anchor bolt 1 and a special anchor bolt long nut 2, which are threaded together. The special anchor bolt long nut 2 has a Y-direction fixing device 3, an X-direction fixing device 5, and a Z-direction fixing device 6 on its side. A roller 4 is provided on the top of the special anchor bolt long nut 2, and the roller 4 is mounted on a track on the side wall of a roadway wall 16. The anchor bolt 1 is movably connected to the roadway wall 16. An acceleration sensor body 10 is installed at the end of the Y-direction fixing device 3, X-direction fixing device 5, and Z-direction fixing device 6 away from the special anchor bolt long nut 2. Multiple convenient mobile device general structures 14 are electrically connected via sensor data connection lines 15, with a take-up assembly 18 installed in the middle of the sensor data connection lines 15.

[0023] The device consists of a convenient moving device overall structure 14, anchor bolts 1, special anchor bolt long nuts 2, rollers 4, Y-direction fixing devices 3, X-direction fixing devices 5, Z-direction fixing devices 6, and a motor 17. The convenient moving device overall structure 14 is made of lightweight, high-strength materials to ensure sufficient durability and stability during tunneling. Anchor bolts 1 and special anchor bolt long nuts 2 are threaded together, allowing for rigid connection with anchor bolts 1 already coupled to the tunnel wall 16, ensuring good signal quality. The rollers 4 have slide rails arranged along the sidewall of the tunnel wall 16 to support smooth movement of the device within the tunnel. The accelerometer sensor body 10 fixing device is designed in a Y-direction... The device features a three-directional modular structure consisting of a fixed device 3 in the X direction, a fixed device 5 in the X direction, and a fixed device 6 in the Z direction. This allows the accelerometer sensor body 10 to acquire signals from three directions. Rollers 4 move along a slide rail. The control system is integrated within the overall architecture 14 of the convenient moving device. The speed and direction of movement are controlled remotely via a remote controller motor 17 and rollers 4. The device is equipped with a wireless data transmission module, enabling real-time transmission of acquired seismic data to a ground server. The key design features of this device are its convenience and efficiency. Its modular design and rapid installation allow for flexible movement and adjustment as the tunneling machine advances, ensuring the continuity and accuracy of the detection process. Simultaneously, a data processing and transmission system is integrated within the device, supporting real-time analysis and remote monitoring, providing effective technical support for geological hazard prediction in mines. This approach eliminates the need to stop production, improves detection accuracy, reduces costs, and enhances mine safety. It demonstrates excellent adaptability to the complex environment of underground coal mines and represents a significant technological innovation for achieving intelligent and precise coal mining.

[0024] Reference Figure 2 and Figure 3 Each of the multiple accelerometer bodies 10 has a sensor tail cone 8 at one end near the long nut 2 of the special anchor rod. The ends of the multiple sensor tail cones 8 away from the accelerometer body 10 are fixedly connected to coupling bayonets 7. The multiple coupling bayonets 7 are respectively threaded into the Y-direction fixing device 3, the X-direction fixing device 5 and the Z-direction fixing device 6. A data transmission module 11 is provided on the side of the accelerometer body 10 away from the sensor tail cone 8. A cover plate 13 is fixedly connected to the side of the data transmission module 11 away from the sensor tail cone 8. A level 12 is installed on the side of the cover plate 13. The data transmission module 11 is electrically connected to the overall structure 14 of the convenient moving device through a data transmission line 9.

[0025] Data transmission line 9, data transmission module 11, and sensor data connection line 15 are used to transmit the collected data. Level 12 and cover plate 13 ensure the levelness of the device and protect the internal components. Y-direction fixing device 3, X-direction fixing device 5, and Z-direction fixing device 6 are connected to special anchor bolt long nut 2 for precise adjustment of the position and direction of the acceleration sensor. The overall architecture 14 of the convenient moving device integrates all the above components to form an integral structure. It is connected in series by anchor bolts 1 on the tunnel wall 16 to complete the convenient installation of the entire sensor.

[0026] Reference Figure 2 and Figure 4 The cable take-up assembly 18 includes an upper cover 1801, a lower cover 1802 fixedly connected to the lower end of the upper cover 1801, a fixing post 1805 fixedly connected to the middle of the lower cover 1802, a limiting post 1804 fixedly connected to the side of the fixing post 1805, and a torsion spring 1803 provided in the middle of the lower cover 1802. One side of the torsion spring 1803 is engaged with the limiting post 1804, and the other side is engaged with the sensor data connection line 15.

[0027] During installation, because the sensor data connection cable 15 is relatively long, it is usually placed on the wall in an arc shape. Workers, machinery, or debris generated by machinery may hit the sensor data connection cable 15, causing it to break. In this case, the sensor data connection cable 15 is passed through the upper cover 1801 and the lower cover 1802, and then secured to the torsion spring 1803. The spring force of the torsion spring 1803 rotates inward to retract the sensor data connection cable 15, thus retracting the long sensor data connection cable 15 inside the upper cover 1801 and the lower cover 1802, preventing workers from tripping and causing a short circuit.

[0028] Reference Figure 4 The lower cover 1802 is provided with two inner cable outlet grooves 18022 that match the sensor data connection cable 15. The inner cable outlet grooves 18022 are shaped like an oblique "Z". The "Z" shape can divide the inlet and outlet of the sensor data connection cable 15 into upper and lower ends, with the inlet end at the upper end and the outlet end at the lower end. When the torsion spring 1803 is wound up, the inlet end and the outlet end are wound up at the same time and enter along the upper and lower ends of the inner cable outlet groove 18022 respectively, preventing the sensor data connection cables 15 on both sides of the upper cover 1801 from being squeezed together.

[0029] Reference Figure 4 The upper cover 1801 is provided with an external cable groove 18011 that matches the sensor data connection line 15 and the internal cable groove 18022;

[0030] Reference Figure 1 A motor 17 is installed on the side of the roller 4 away from the special anchor bolt long nut 2.

[0031] Working Principle: The device consists of a convenient moving device overall structure 14, anchor bolt 1, special anchor bolt long nut 2, roller 4, Y-direction fixing device 3, X-direction fixing device 5, Z-direction fixing device 6, and motor 17. The convenient moving device overall structure 14 is made of lightweight and high-strength materials to ensure sufficient durability and stability during tunneling. Anchor bolt 1 and special anchor bolt long nut 2 are threaded together, which can rigidly connect with the anchor bolt 1 already coupled to the tunnel wall 16 to ensure good signal quality. The roller 4's slide rail is arranged along the side wall of the tunnel wall 16 to support the smooth movement of the device in the tunnel. The acceleration sensor body 10 is fixed by a design that... The three-directional modular structure of the Y-direction fixing device 3, X-direction fixing device 5, and Z-direction fixing device 6 allows the accelerometer body 10 to obtain signals from three directions. The roller 4 moves along the slide rail. The control system is integrated into the overall architecture 14 of the convenient moving device. The speed and direction of movement are controlled by the remote controller motor 17 and roller 4. The device is equipped with a wireless data transmission module, which can transmit the acquired seismic data to the ground server in real time. The key to the design of this device lies in its convenience and efficiency. Through modular design and rapid installation, the equipment can be flexibly moved and adjusted as the tunneling machine advances, ensuring the continuity and accuracy of the detection process.

[0032] During installation, because the sensor data connection cable 15 is relatively long, it is usually placed on the wall in an arc shape. Workers, machinery, or debris generated by machinery may hit the sensor data connection cable 15, causing it to break. In this case, the wire of the sensor data connection cable 15 is passed through the upper cover 1801 and the lower cover 1802, and then secured to the torsion spring 1803. When the torsion spring 1803 retracts, the inlet and outlet ends retract simultaneously, entering along the upper and lower ends of the inner outlet groove 18022 respectively, preventing the sensor data connection cables 15 on both sides of the upper cover 1801 from being squeezed together. The spring force of the torsion spring 1803 rotates inward to retract the sensor data connection cable 15, shrinking the long sensor data connection cable 15 inside the upper cover 1801 and the lower cover 1802, preventing workers from tripping and causing short circuits.

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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
