[0002] Tunnels are key nodes in transportation networks, and their structural health directly impacts traffic safety and project lifespan. Tunnels are particularly susceptible to minor deformations, such as vault settlement and sidewall displacement, particularly under long-term exposure to geological pressure and vehicle loads. To promptly capture these deformations, millimeter-wave radar equipment is typically used for tunnel deformation monitoring.

[0042] The effect and working principle of the entire mechanism are as follows:

[0043] During the installation and maintenance phase, when the radar body 1 needs to be installed directly below the tunnel vault monitoring point, the controller 221 is first connected to the external power supply, and then the mounting column 201 is installed at a suitable position in the tunnel. Then, with the cooperation of another auxiliary hole 203, the radar body 1 is installed on the top of the slide 213, and then the motor 205 is started by the controller 221. At this time, the started motor 205 will drive the round rod 208 to rotate between the inside of the two perforated seats 207 with the cooperation of the support frame 204, the mounting column 201 and the rectangular plate 206, and the rotating round rod 208 will drive both winding wheels 209 to rotate, and at the same time, the two rotating winding wheels 209 will cooperate with the corresponding cylindrical holes 210. , so that the corresponding steel wire ropes 212 are all wound up, and the two steel wire ropes 212 for winding operation will drive the slide plate 213 to move vertically upward under the cooperation of the corresponding cylindrical blocks 214 and the slide groove 202. At the same time, the slide plate 213 for vertical upward movement will drive the radar body 1 and the iron sheet 215 to move vertically upward. When the radar body 1 moves vertically upward to the point where it can no longer move, the tops of the two cylindrical blocks 214 just touch the bottom of the rectangular plate 206, and the controller 221 will directly turn off the motor 205.

At this time, the closed electric push rod 218 will stop the electromagnet 220 from moving horizontally. Then, the controller 221 will start the electric push rod 218 and the motor 205. At this time, the started motor 205 will, with the cooperation of the above-mentioned components, make both steel ropes 212 unwind. At the same time, the started electric push rod 218 will move in the rectangular block 217. , U-shaped frame 216, mounting block 219, started electromagnet 220, iron sheet 215, two unwinding steel ropes 212, two cylindrical holes 210, two auxiliary slots 211, two cylindrical blocks 214 and one of the auxiliary holes 203 cooperate to drive the slide plate 213 to move horizontally, and the horizontally moving slide plate 213 will drive the radar body 1 to move horizontally. When the radar body 1 moves to the point where it can no longer move, the controller 221 will directly turn off the electric push rod 218 and the motor 205. At the same time, the radar body 1 that has stopped moving is just below the tunnel vault monitoring point, and the installation operation of the radar body 1 is completed. When it is necessary to remove the installed radar body 1, directly perform the reverse operation according to the above steps.The radar body 1 is reset and moved until it returns to its original position, and then the radar body 1 is removed from the slide plate 213 by using the cooperation of another auxiliary hole 203;

[0044] During the protection phase, when the controller 221 needs to be used, first loosen the hand-tightening bolt 303, then apply a force to the shell cover 302 to rotate the shell cover 302 around the corner of the front surface of the shell 301 until the shell cover 302 rotates to a suitable angle, and then the controller 221 can be used. When the controller 221 is no longer in use, directly follow the above steps in reverse until the hand-tightening bolt 303 is restored to its original position.
