During the operation and use of the tunnel structure, the convergence deformation of the tunnel section reflects the performance evolution of its structure and is an important basis for judging the safety and stability of the structure and its operation and maintenance.

[0004] However, the above technical solution has the following shortcomings: when using the device to monitor the tunnel, workers need to set up a device for monitoring in multiple locations in the tunnel, so as to ensure that when the tunnel is deformed, the workers are notified to leave the tunnel as soon as possible, thereby increasing the maintenance cost of the tunnel.

[0008] Preferably, a fixed block is slidably arranged on the rolling seat, the connecting shaft is rotatably connected to the fixed block, and a spring is arranged between the fixed block and the rolling seat.

[0009] Preferably, a plurality of detectors are evenly distributed on the rolling seat, and the plurality of detectors are all located at the fixed block.

[0010] Preferably, a control console is provided on the top of the monitoring box for damping rotation, and a control component is provided on the control console.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] When the utility model is used, the worker holds the push handle to push the monitoring box to the tunnel wall and flush with the tunnel, then pulls out two sets of rolling components, allows multiple abutment wheels on the rolling components to abut against the tunnel wall, then fixes the position of the auxiliary arm b by a nut, and then the worker controls the infrared distance measuring instrument to monitor toward the top of the tunnel. When the worker pushes the monitoring box along the tunnel, the distance between the infrared distance measuring instrument and the top of the tunnel is fixed. When the data returned by the infrared distance measuring instrument is abnormal, the worker can warn other workers, thereby reducing the cost required for monitoring tunnel deformation.

[0018] Embodiment 1

[0019] like Figure 1-Figure 3 As shown, a tunnel deformation monitoring device proposed in this embodiment includes a monitoring box 1 and an auxiliary mechanism, wherein a push handle 2 and a moving component 3 are provided on the monitoring box 1, the moving component 3 is located at the bottom of the monitoring box 1, and an infrared distance measuring instrument 71 is rotatably provided on the top of the monitoring box 1; the auxiliary mechanism, which has two groups relatively slidably arranged on the monitoring box 1, and the auxiliary mechanism includes two groups of rolling components slidably arranged side by side on the monitoring box 1, and the rolling component includes an auxiliary arm a8 and an auxiliary arm b9 slidably arranged on the monitoring box 1, a rolling seat 10 rotatably arranged on the auxiliary arm a8 and the auxiliary arm b9, and a plurality of abutment wheels 12 evenly arranged on the rolling seat 10, a plurality of threaded holes evenly distributed on the auxiliary arm b9, and a nut 11 rotatably arranged on the monitoring box 1, and the nut 11 is threadedly connected to the threaded hole.

[0020] When this embodiment is used, the worker holds the push handle 2 to push the monitoring box 1 to the side of the tunnel wall and flush with the tunnel, then pulls out two sets of rolling assemblies to allow the multiple abutment wheels 12 on the rolling assemblies to abut against the tunnel wall, then fixes the position of the auxiliary arm b9 through the nut 11, and then the worker controls the infrared distance meter 71 to monitor toward the top of the tunnel. When the worker pushes the monitoring box 1 along the tunnel, the distance between the infrared distance meter 71 and the top of the tunnel is fixed. When the data returned by the infrared distance meter 71 is abnormal, the worker can warn other workers, thereby reducing the cost of monitoring tunnel deformation.

[0021] Embodiment 2

[0022] like Figure 2 and Figure 3 As shown, a tunnel deformation monitoring device proposed in this embodiment, compared with the first embodiment, in this embodiment, the abutment wheel 12 includes a wheel body 121 and a connecting shaft 122 arranged at both ends of the wheel body 121, and the wheel body 121 is provided with a pressure sensing belt 13 along the outer circumferential surface. When the pressure sensing belt 13 abuts against the wall, it will emit a green light and return the corresponding data of the monitoring box 1. On the contrary, when the pressure sensing belt 13 does not abut against an object, it will emit a red light. A fixed block 14 is slidably arranged on the rolling seat 10, and the connecting shaft 122 is rotatably connected to the fixed block 14. A spring 15 is arranged between the fixed block 14 and the rolling seat 10.

[0023] A plurality of detectors 16 are evenly distributed on the rolling seat 10, and the plurality of detectors 16 are all located at the fixed block 14. When the abutment wheel 12 contacts the wall and a convexity appears on the shape of the wall, the abutment wheel 12 will drive the fixed block 14 to move toward the direction of the spring 15. At the same time, the abutment wheel 12 will contact the plurality of detectors 16 in sequence. According to the number of contacts of the abutment wheel 12, the workers can timely understand the deformation of the tunnel according to the data received by the monitoring box 1, thereby reducing the probability of the workers' personal safety being threatened.

[0024] When this embodiment is in use, the abutment wheel 12 will always be in contact with the wall, and the pressure sensing belt 13 will transmit the corresponding data to the monitoring box 1. When the worker pushes the monitoring box 1, the pressure sensing belt 13 and the detector 16 can be used to understand the deformation condition of the side of the tunnel, thereby increasing the amount of data obtained by the worker in one detection.

[0025] Embodiment 3

[0026] like Figure 1 As shown, a tunnel deformation monitoring device proposed in this embodiment, compared with the first embodiment, in this embodiment, a control console is provided on the top of the monitoring box 1 for damping rotation, and a control component 4 is provided on the control console. A rotating frame 5 is provided on the top of the monitoring box 1, and a motor 6 is provided on the rotating frame 5. The output end of the motor 6 is connected to a rotating table 7, and an infrared distance meter 71 is provided on the top of the rotating table 7. The control component 4 is electrically connected to the motor 6, the infrared distance meter 71, the pressure sensing belt 13 and the detector 16.

[0027] When this embodiment is used, the worker controls the motor 6 through the control component 4 to drive the rotating frame 5 to rotate to the direction of the point the worker wants to detect, and then the worker checks the data returned by the infrared distance meter 71, the pressure sensing belt 13 and the detector 16 through the control component 4. The control component 4 will make a sound when the data is abnormal, thereby reminding the worker to evacuate other people, thereby avoiding workers staying in the tunnel when the tunnel collapses.

[0028] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
