Description

Technical Field

[0001] This utility model relates to the field of tunnel deformation monitoring technology, specifically a tunnel deformation monitoring device. Background Technology

[0002] With the rapid development of transportation infrastructure construction, tunnel engineering is widely used in railways, highways, and other fields. During long-term use, tunnels are highly susceptible to deformation due to factors such as changes in geological conditions, vehicle loads, and groundwater erosion. If deformation is not detected and addressed in a timely manner, it can lead to serious safety accidents such as collapses, threatening lives and property. Therefore, tunnel deformation monitoring has become a crucial link in ensuring the safe operation of tunnels.

[0003] Currently, commonly used tunnel deformation monitoring devices do not have auxiliary cleaning functions during use. However, tunnel sidewalls are exposed to complex environments for a long time and are prone to accumulating a large amount of dust, mud, water stains, oil stains and other debris. The presence of these debris will affect data acquisition, resulting in inaccurate detection results and failing to meet the requirements. Therefore, we propose a tunnel deformation monitoring device. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a tunnel deformation monitoring device that has the advantage of accurate monitoring. It solves the problem that currently used tunnel deformation monitoring devices do not have auxiliary cleaning functions during use. However, tunnel sidewalls are exposed to complex environments for a long time and are prone to accumulating a large amount of dust, mud, water stains, oil stains and other debris. The presence of these debris will affect data acquisition, resulting in inaccurate detection results and failing to meet the requirements of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tunnel deformation monitoring device, comprising a housing, a protective cover fixedly connected to the right side of the top of the housing, a first motor disposed on the right side of the housing, a housing fixedly connected to the output end of the first motor, a connecting frame disposed on one side of the housing, a roller movably connected to one side of the connecting frame, an electric slide fixedly connected to the central shaft on the back of the housing, an adjusting frame fixedly connected to one side of the electric slide, a second motor fixedly connected to the top of the adjusting frame, and a brush roller fixedly connected to the output end of the second motor.

[0006] Preferably, a third motor is fixedly connected to the left side of the top of the housing, a lead screw is fixedly connected to the output end of the third motor, a threaded sleeve is threaded onto the surface of the lead screw, an adjusting rod is fixedly connected to one side of the threaded sleeve, one side of the adjusting rod is fixedly connected to the first motor, an elastic telescopic rod is fixedly connected to the front side of the inner cavity of the housing, a rectangular plate is fixedly connected to the rear side of the elastic telescopic rod, a pressure sensor is fixedly connected to the rear side of the rectangular plate, a connecting plate is fixedly connected to the rear side of the pressure sensor, a crossbar is fixedly connected to the rear side of the connecting plate, one side of the crossbar is fixedly connected to the connecting frame, and an tilt sensor is fixedly connected to the bottom of the housing.

[0007] Preferably, a sliding rod is fixedly connected to one side of the adjusting frame, and a sliding sleeve is slidably connected to the surface of the sliding rod, with one side of the sliding sleeve fixedly connected to the housing.

[0008] Preferably, a vertical rod is slidably connected to the right side of the inner cavity of the threaded sleeve, and the top and bottom of the vertical rod are fixedly connected to the housing.

[0009] Preferably, the bottom of the lead screw is movably connected to the housing via a bearing, and a rectangular groove is provided on the front side of the housing.

[0010] Preferably, a wireless transceiver, an alarm light, and a PLC controller are fixedly connected sequentially from top to bottom on the left side of the housing. The wireless transceiver is bidirectionally electrically connected to a remote terminal, and an audible and visual alarm is fixedly connected to the output end of the remote terminal.

[0011] Compared with the prior art, the present invention provides a tunnel deformation monitoring device, which has the following beneficial effects:

[0012] 1. When no testing is required, this utility model starts the first motor via the PLC controller, which drives the housing to rotate, causing the connecting frame to rotate. The connecting frame drives the roller to rotate, aligning the roller with the protective cover. Then, the height of the roller is adjusted so that it moves into the inner cavity of the protective cover, preventing debris from adhering to the roller surface. Before testing, the PLC controller controls the electric slide and the second motor to operate. The second motor drives the brush roller to rotate, which in turn drives the adjusting frame to move. The adjusting frame drives the second motor to move, which in turn drives the brush roller to move, cleaning the tunnel sidewall to be tested. Then, the roller is returned to its original position.

[0013] 2. During testing, this utility model uses an inclination sensor to detect the inclination angle. If the inclination is not horizontal, it indicates that the entire tunnel sidewall is tilted. A signal is then transmitted to the PLC controller, which activates the warning lights. Simultaneously, a wireless transceiver transmits the signal to a remote terminal, which activates an audible and visual alarm to alert staff. When the tunnel is horizontal, a third motor is activated. This motor drives a lead screw, which in turn moves a threaded sleeve. The threaded sleeve moves an adjusting rod, which in turn moves the first motor, which in turn moves the housing, causing the rollers to move. As the tunnel sidewall deforms, the rollers move back and forth during their vertical movement, causing the connecting frame to move back and forth. The connecting frame moves the crossbar back and forth, which in turn moves the connecting plate back and forth. The connecting plate presses against the pressure sensor, causing a change in pressure. This signal is then transmitted to the PLC controller, which also activates the warning lights. Simultaneously, a wireless transceiver transmits the signal to a remote terminal, which activates the audible and visual alarm, allowing staff to promptly check and address the issue.

[0023] The specific function of this technical solution is as follows: When no inspection is required, the first motor 3 is started by the PLC controller 23, which drives the housing 4 to rotate, thereby causing the connecting frame 5 to rotate. The connecting frame 5 drives the roller 6 to rotate, so that the roller 6 corresponds to the protective cover 2. Then, the height of the roller 6 is adjusted so that the roller 6 moves into the inner cavity of the protective cover 2 to prevent debris from adhering to the surface of the roller 6. Before inspection, the electric slide table 7 and the second motor 9 are controlled by the PLC controller 23. The second motor 9 drives the brush roller 10 to rotate, and the electric slide table 7 drives the adjusting frame 8 to move. The adjusting frame 8 drives the second motor 9 to move, thereby driving the brush roller 10 to move and clean the tunnel sidewall to be inspected. Then, the roller 6 is returned to its original position. Example

[0024] Based on Embodiment 1, this utility model is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a third motor 12 is fixedly connected to the left side of the top of the housing 1. A lead screw 13 is fixedly connected to the output end of the third motor 12. A threaded sleeve 14 is threaded onto the surface of the lead screw 13. An adjusting rod 15 is fixedly connected to one side of the threaded sleeve 14. One side of the adjusting rod 15 is fixedly connected to the first motor 3. An elastic telescopic rod 16 is fixedly connected to the front side of the inner cavity of the housing 4. A rectangular plate 17 is fixedly connected to the rear side of the elastic telescopic rod 16. A pressure sensor 18 is fixedly connected to the rear side of the rectangular plate 17. A connecting plate 19 is fixedly connected to the rear side of the pressure sensor 18. The rear side of the connecting plate 19 is fixedly... A crossbar 20 is connected, with one side of the crossbar 20 fixedly connected to the connecting frame 5. An angle sensor 11 is fixedly connected to the bottom of the housing 1. A vertical rod is slidably connected to the right side of the inner cavity of the threaded sleeve 14, and the top and bottom of the vertical rod are fixedly connected to the housing 1. The bottom of the lead screw 13 is movably connected to the housing 1 through a bearing. A rectangular groove is opened on the front of the housing 1. A wireless signal transceiver 21, an alarm light 22, and a PLC controller 23 are fixedly connected from top to bottom on the left side of the housing 1. The wireless signal transceiver 21 is bidirectionally electrically connected to a remote terminal, and an audible and visual alarm is fixedly connected to the output end of the remote terminal.

[0025] The specific function of this technical solution is as follows: During detection, the tilt angle sensor 11 detects the tilt angle value. If the tilt angle is not detected, it indicates that the entire tunnel sidewall is tilted. At this time, the signal is transmitted to the PLC controller 23, which then controls the warning light 22 to work. Simultaneously, the signal is transmitted to the remote terminal via the wireless transceiver 21. The remote terminal controls the audible and visual alarm to work, alerting the staff. When the tilt angle is detected, the third motor 12 is activated. The third motor 12 drives the lead screw 13 to rotate, the lead screw 13 drives the threaded sleeve 14 to move, and the threaded sleeve 14 drives the adjusting rod 15 to move, which in turn drives the first motor... The movement of machine 3, in turn, moves the housing 4, which in turn moves the roller 6. After the tunnel sidewall deforms, the roller 6 will also move back and forth during its vertical movement, which will move the connecting frame 5 back and forth. The connecting frame 5 moves the crossbar 20 back and forth, and the crossbar 20 moves the connecting plate 19 back and forth. The connecting plate 19 presses against the pressure sensor 18, causing the pressure value to change. The signal is then transmitted to the PLC controller 23, which will also control the warning light 22 to work. At the same time, the signal is transmitted to the remote terminal through the wireless signal transceiver 21. The remote terminal controls the sound and light alarm to work, which is convenient for staff to check and deal with in a timely manner.

[0026] Working principle: When no inspection is required, the first motor 3 is started by the PLC controller 23, which drives the housing 4 to rotate, thereby causing the connecting frame 5 to rotate. The connecting frame 5 drives the roller 6 to rotate, so that the roller 6 corresponds to the protective cover 2. Then, the height of the roller 6 is adjusted so that the roller 6 moves into the inner cavity of the protective cover 2 to prevent debris from adhering to the surface of the roller 6. Before inspection, the electric slide table 7 and the second motor 9 are controlled by the PLC controller 23. The second motor 9 drives the brush roller 10 to rotate, and the electric slide table 7 drives the adjusting frame 8 to move. The adjusting frame 8 drives the second motor 9 to move, thereby driving the brush roller 10 to move and clean the tunnel sidewall to be inspected. Then, the roller 6 is returned to its original position.

[0027] During testing, the tilt angle is detected by the tilt sensor 11. If the tilt angle is not detected, it indicates that the entire tunnel sidewall is tilted. At this point, a signal is transmitted to the PLC controller 23, which then controls the warning light 22 to operate. Simultaneously, the signal is transmitted to a remote terminal via the wireless transceiver 21. The remote terminal controls the audible and visual alarm to alert personnel. When the tilt angle is detected, the third motor 12 is activated. The third motor 12 drives the lead screw 13 to rotate, which in turn drives the threaded sleeve 14 to move. The threaded sleeve 14 then drives the adjusting rod 15, which in turn moves the first motor 3. Moving the housing 4 causes the rollers 6 to move. After the tunnel sidewall deforms, the rollers 6 will move back and forth during their vertical movement, which will cause the connecting frame 5 to move back and forth. The connecting frame 5 will cause the crossbar 20 to move back and forth, and the crossbar 20 will cause the connecting plate 19 to move back and forth. The connecting plate 19 will press against the pressure sensor 18, causing the pressure value to change. The signal will then be transmitted to the PLC controller 23, which will also control the warning light 22 to work. At the same time, the signal will be transmitted to the remote terminal through the wireless transceiver 21. The remote terminal will control the sound and light alarm to work, making it convenient for staff to check and deal with the situation in a timely manner.
