[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model provides a detachable tunnel deformation monitoring device. Figure 1-4 As shown, the detachable tunnel deformation monitoring device includes: a mounting plate 1, which is fixedly mounted on one side of the wall inside the tunnel; a mounting groove 2, which is opened on the mounting plate 1; a mounting block 3, which can be arranged in the mounting groove 2; a laser ranging sensor body 4, which is fixedly mounted on a side of the mounting block 3 outside the mounting groove 2, and the laser ranging sensor body 4 can be used to monitor the deformation of the tunnel structure; a mounting mechanism, which is arranged on the mounting plate 1, and is used to install the mounting block 3 in the mounting groove 2; a disassembly mechanism, which is arranged on the mounting plate 1, and is used to quickly disassemble the mounting block 3 from the mounting groove 2; a positioning mechanism, which is arranged on the mounting plate 1, and is used to control the state of the mounting groove 2.

[0022] In this embodiment, during the tunnel construction and operation process, the laser distance measuring sensor is difficult to be quickly disassembled for maintenance after being fixedly installed. Through this device, real-time and continuous monitoring of tunnel structure deformation can be achieved, while improving maintenance efficiency.

[0023] The device consists of several key components, each of which carries a specific number and plays an indispensable role:

[0024] Mounting plate 1: Fixedly installed on one side of the tunnel wall, serving as the basic supporting structure of the entire monitoring device.

[0025] Mounting groove 2: It is provided on the mounting plate 1 and is used to accommodate and position the mounting block 3 to ensure that the laser ranging sensor body 4 is accurately installed.

[0026] The mounting block 3 can be arranged in the mounting groove 2 as a fixing carrier of the laser ranging sensor body 4 to realize the connection between the sensor and the mounting plate.

[0027] Laser ranging sensor body 4: fixedly mounted on one side of the mounting block 3 outside the mounting slot 2, used to monitor the deformation of the tunnel structure. The sensor body can obtain real-time data on changes in the tunnel structure, providing data support for timely warning of potential structural problems and safety hazards.

[0028] Mounting mechanism: It is arranged on the mounting plate 1 and is used to firmly mount the mounting block 3 in the mounting groove 2. The design of the mounting mechanism ensures the stability of the sensor body during operation and prevents displacement or falling off due to vibration or external force.

[0029] Disassembly mechanism: It is also provided on the mounting plate 1 and is used to quickly disassemble the mounting block 3 from the mounting groove 2. The introduction of this mechanism greatly improves the maintenance efficiency. When the laser ranging sensor body fails, the maintenance personnel can quickly disassemble and replace the new sensor, reducing the maintenance time and cost.

[0030] Positioning mechanism: It is arranged on the mounting plate 1 and can control the locking and unlocking states of the mounting slot 2 to ensure the accuracy and convenience of the mounting block 3 during the installation and removal process.

[0031] In a further preferred embodiment of the utility model, the mounting mechanism includes limit grooves 5 opened on the upper and lower sides of the mounting block 3, and compression grooves 6 are opened on the upper and lower sides of the mounting groove 2. A limit block 7 is slidably provided in the compression groove 6, and the limit block 7 can be slidably extended into the limit groove 5.

[0032] In this embodiment, the mounting mechanism includes limit slots 5 provided on the upper and lower sides of the mounting block 3 and compression slots 6 provided on the upper and lower sides of the mounting slot 2. Limit blocks 7 are slidably provided in the compression slots 6, and these limit blocks 7 can slide and extend into the limit slots 5.

[0033] The advantage of this design is that when the mounting block 3 is placed in the mounting groove 2, the limiting block 7 in the compression groove 6 slides into the limiting groove 5, thereby limiting the vertical direction of the mounting block 3. This limiting effect ensures the stability of the mounting block 3 in the mounting groove 2, thereby preventing the laser ranging sensor body 4 from being displaced or falling off due to external force or vibration.

[0034] This mounting mechanism is not only simple in structure, but also easy to operate. When the laser distance measuring sensor needs to be installed or removed, the installation block 3 can be easily installed or removed by simply performing appropriate operations on the stop block 7.

[0035] In a further preferred embodiment of the utility model, the disassembly mechanism includes a sliding sleeve 8 slidably mounted on the outside of the mounting plate 1, and a pull rope 9 is fixedly mounted on one side of the limit block 7 located in the compression groove 6, and one end of the pull rope 9 extending outside the mounting plate 1 is fixedly connected to the sliding sleeve 8.

[0036] In this embodiment, the disassembly mechanism includes a sleeve 8 slidably mounted on the outside of the mounting plate 1. At the same time, a pull rope 9 is fixedly mounted on one side of the limit block 7 in the compression groove 6, and the end of the pull rope 9 extending outside the mounting plate 1 is fixedly connected to the sleeve 8.

[0037] This design makes the disassembly process simpler and more efficient. When the installation block 3 needs to be disassembled, the maintenance personnel only need to slide the sleeve 8 inwards. Due to the connection of the pull rope 9, the limit block 7 will be pulled and moved into the compression groove 6, thereby disengaging from the limit groove 5. Once the limit block 7 is completely disengaged from the limit groove 5, the installation block 3 can be easily removed from the installation groove 2.

[0038] This disassembly mechanism is not only easy to operate, but also can quickly respond to maintenance needs. When the laser distance sensor body 4 fails, maintenance personnel can quickly use the disassembly mechanism to disassemble and replace it, thereby shortening maintenance time and reducing maintenance costs.

[0039] In a further preferred embodiment of the utility model, the positioning mechanism includes a fixing groove 10 opened on one side of the top of the sliding sleeve 8, a fixing plate 11 is slidably provided in the fixing groove 10, a guide groove 12 is opened on the top of the mounting plate 1, the sliding sleeve 8 covers the guide groove 12, one end of the fixing plate 11 located outside the sliding sleeve 8 extends into the guide groove 12 and slides in contact with the inner wall of the guide groove 12, a supporting groove 13 is opened on one side of the guide groove 12, and the fixing plate 11 can extend into the supporting groove 13.

[0040] In this embodiment, the positioning mechanism includes a fixing groove 10 provided on one side of the top of the sliding sleeve 8, in which a fixing plate 11 is slidably provided. At the same time, a guide groove 12 is provided on the top of the mounting plate 1, and the sliding sleeve 8 covers the guide groove 12, so that the end of the fixing plate 11 located outside the sliding sleeve 8 can extend into the guide groove 12 and slide in contact with the inner wall of the guide groove 12. In addition, a supporting groove 13 is provided on one side of the guide groove 12, and the fixing plate 11 can extend into the supporting groove 13.

[0041] This design enables the positioning mechanism to accurately control the state of the mounting groove 2. When the sleeve 8 is in the initial position, the limit block 7 is in a state of extending in the mounting groove 2. At this time, the mounting block 3 can be locked in the mounting groove 2 by the limit block 7 and cannot be removed. When the mounting block 3 needs to be removed, the maintenance personnel first slide the sleeve 8 outward. At this time, the pull rope 9 will pull the limit block 7 to move into the compression groove 6, thereby releasing the lock on the mounting block 3. Then, the maintenance personnel can continue to slide the sleeve 8 so that the fixed plate 11 extends into the guide groove 12 and slides along it. When the fixed plate 11 falls into the support groove 13 under the action of gravity, the position of the sleeve 8 is fixed. At this time, the limit block 7 is located in the compression groove 6, and the mounting block 3 can be smoothly removed from the mounting groove 2.

[0042] This positioning mechanism is not only easy to operate, but also accurate in positioning. The sliding of the fixing plate 11 in the guide groove 12 and the support groove 13 ensures the stability and reliability of the sliding sleeve 8 during the movement, thereby preventing the limiting block 7 from entering the limiting groove 5 again during the disassembly of the mounting block 3, thereby affecting the disassembly process.

[0043] In a further preferred embodiment of the utility model, a pair of support rods 14 are fixedly installed in the support groove 13, and the same support plate 15 is slidably installed on the two support rods 14. The fixed plate 11 can contact the support plate 15, and a first spring 16 is sleeved on the support rod 14. The two ends of the first spring 16 are fixedly connected to the inner wall of the support groove 13 and the support plate 15 respectively.

[0044] In this embodiment, a pair of support rods 14 are fixedly installed in the support groove 13, and a same support plate 15 is slidably installed on the two support rods 14. When the fixed plate 11 slides to the position of the support groove 13, it can contact with the support plate 15 and be supported by the support plate 15. This design makes the position of the fixed plate 11 in the support groove 13 more stable and less likely to shake or move.

[0045] In addition, in order to provide sufficient supporting force and ensure stable sliding of the support plate 15 on the support rod 14, a first spring 16 is sleeved on the support rod 14. The two ends of the first spring 16 are respectively fixedly connected to the inner wall of the support groove 13 and the support plate 15, so that when the fixed plate 11 contacts the support plate 15, the first spring 16 will be compressed to generate a certain rebound force, further enhancing the supporting effect of the support plate 15 on the fixed plate 11.

[0046] This optimally designed positioning mechanism not only improves stability, but also enables the sliding sleeve 8 to be automatically locked after being moved into position, without the need for additional locking operations. When the mounting block 3 needs to be removed, the support plate 15 can move upward to push the fixing plate 11 upward so that the fixing plate 11 can enter the track of the guide groove 12, thereby loosening the fixing of the sliding sleeve 8, and then the mounting block 3 can be easily removed. This design simplifies the operation process and improves maintenance efficiency.

[0047] In a further preferred embodiment of the utility model, a pressing groove 17 is opened on the front side of the mounting groove 2, and pressing rods 18 are fixedly installed on both sides of the pressing groove 17. The same pressing plate 19 is slidably installed on the two pressing rods 18. The mounting block 3 can contact the pressing plate 19, and a pull rope 20 is fixedly installed on one side of the top of the pressing plate 19. One end of the pull rope 20 extends into the support groove 13 and is fixedly connected to the support plate 15.

[0048] In this embodiment, a pressing groove 17 is provided at the front side of the installation groove 2, and pressing rods 18 are fixedly installed on both sides of the pressing groove 17. The same pressing plate 19 is slidably installed on the two pressing rods 18, and when the installation block 3 is placed in the installation groove 2, it can contact the pressing plate 19.

[0049] In addition, a pull rope 20 is fixedly installed on one side of the top of the pressure plate 19, and one end of the pull rope 20 extending into the support groove 13 is fixedly connected to the support plate 15. This design forms a linkage mechanism between the pressure plate 19, the pull rope 20 and the support plate 15. When the mounting block 3 is placed in the mounting groove 2 and contacts the pressure plate 19, the pressure plate 19 will be subjected to downward pressure, and the support plate 15 will be pulled downward on the support rod 14 by the pull rope 20. As the support plate 15 slides, the first spring 16 will be compressed. At this time, the sliding sleeve 8 is in the initial state, and the limit block 7 extends in the mounting groove 2, so that it can be locked in the mounting groove 2 by the limit block 7 as the mounting block 3 gradually enters.

[0050] When it is necessary to remove the mounting block 3, the maintenance personnel only need to slide the sleeve 8 inward and outward, and the fixing plate 11 can be driven to slide along the guide groove 12 and gradually enter the support groove 13. At this time, the position of the sleeve 8 is fixed, and the limit block 7 remains in the state of being located in the compression groove 6, and then the mounting block 3 can be pulled outward. As the mounting block 3 is pulled out, the pressure of the pressure plate 19 is gradually relaxed. Under the rebound force of the first spring 16, the support plate 15 will automatically slide upward, so that the fixing plate 11 can be pushed upward to the track of the guide groove 12. At this time, the limit groove 5 has left the bottom of the compression groove 6, and the limit block 7 can no longer enter the limit groove 5, so that the mounting block 3 can be easily taken out from the mounting groove 2.

[0051] This improved design not only simplifies the installation and disassembly process and improves the convenience of operation, but also ensures the stability and reliability of the mounting block 3 in the mounting groove 2 through the linkage mechanism. At the same time, due to the use of a mechanical locking and unlocking mechanism, no additional electrical or pneumatic components are required, which reduces the cost and maintenance difficulty of the device.

[0052] In a further preferred embodiment of the utility model, a compression rod 21 is fixedly installed in the compression groove 6, a sliding groove 22 is opened in the limit block 7, the compression rod 21 extends into the sliding groove 22 and slides in contact with the inner wall of the sliding groove 22, and a second spring 23 is sleeved on the compression rod 21, and the two ends of the second spring 23 are respectively fixedly connected to the inner wall of the compression groove 6 and the limit block 7.

[0053] In this embodiment, a compression rod 21 is fixedly installed in the compression groove 6, and a slide groove 22 is provided in the limit block 7. The compression rod 21 extends into the slide groove 22 and slides in contact with the inner wall of the slide groove 22. This design ensures that the limit block 7 can move stably along the compression rod 21 during the sliding process, and is not prone to deviation or shaking.

[0054] In addition, in order to provide sufficient restoring force and ensure that the limit block 7 can smoothly slide into or out of the compression groove 6, a second spring 23 is also sleeved on the compression rod 21. The two ends of the second spring 23 are respectively fixedly connected to the inner wall of the compression groove 6 and the limit block 7, so that when the limit block 7 is moved into the compression groove 6 by an external force, the second spring 23 will be compressed and store energy; and when the external force disappears, the second spring 23 will release energy and push the limit block 7 to move out of the compression groove 6, thereby restoring to the initial position.

[0055] The optimized compression groove 6 and the limit block 7 not only improve the stability and sliding smoothness, but also make the whole disassembly mechanism more reliable and durable. When disassembling the installation block 3, the limit block 7 can be easily pulled into the compression groove 6 by using the sliding sleeve 8 and the pull rope 9, thereby releasing the lock of the installation block 3; and during the installation process, the installation block 3 only needs to be placed in the installation groove 2, and the limit block 7 will automatically slide into the limit groove 5 under the action of the second spring 23, completing the locking of the installation block.

[0056] In summary, compared with the related art, the detachable tunnel deformation monitoring device of the utility model achieves the purpose of convenient installation and disassembly, and improved stability and reliability as a whole. By optimizing the design of the installation mechanism, disassembly mechanism and positioning mechanism, the installation block 3 can be stably installed in the installation groove 2 and can be easily disassembled when needed, thereby improving maintenance efficiency. At the same time, by adding a linkage mechanism and improving the structure of the compression groove 2 and the limit block 7, the stability and sliding smoothness of the device are further enhanced. These improvements make the device more reliable and efficient in tunnel deformation monitoring, and provide better technical support for the construction and operation of the tunnel.
