[0024] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0025] like Figure 1-Figure 6 As shown, the mine tunnel deformation measuring device provided in this embodiment includes a frame 1 and a plurality of measuring rods 2. The frame 1 is provided with a plurality of mounting grooves 8 which cooperate with the measuring rods 2. The measuring rods 2 penetrate the frame 1 through the mounting grooves 8. A spring 9 located on the outside of the measuring rod 2 is installed inside the mounting grooves 8. A limiting plate 10 which cooperates with the spring 9 is installed on the outside of the measuring rod 2. A warning light 3 and an alarm 4 are installed on the front of the spring 9. A plurality of mounting plates 5 are installed on the inner side of the frame 1. Infrared switches 6 which cooperate with the warning light 3 and the alarm 4 are installed on the plurality of mounting plates 5. By setting the measuring rod 2, infrared switch 6, warning light 3 and alarm 4, the frame 1 can be installed in the tunnel when in use. When the tunnel is deformed, the measuring rod 2 will be squeezed and the measuring rod 2 will move toward the inside of the frame 1. At this time, when the measuring rod 2 blocks the infrared light emitted by the infrared switch 6, the warning light 3 and the alarm 4 will be activated to remind the underground workers. At the same time, the workers can also know the deformation of the tunnel according to the distance moved by the measuring rod 2. The device can be installed inside the tunnel for long-term measurement work, and can also promptly remind the underground workers through the warning light 3 and the alarm 4.

[0026] The warning light 3 and the alarm 4 are symmetrically installed on the front side of the frame 1. The mounting plate 5 includes a plate body 501. Through holes 502 are provided at the four corners of the plate body 501. The plate body 501 is installed on the inner side of the frame 1 through the through holes 502 and bolts. A plurality of evenly distributed screw holes 503 are provided in the middle of the plate body 501. The infrared switch 6 is installed on the plate body 501 through screws and screw holes 503. When in use, the plate body 501 can be conveniently installed on the inner side of the frame 1 through the through holes 502 and bolts. Through the setting of a plurality of screw holes 503, the position of the infrared switch 6 can be conveniently adjusted in conjunction with the screws, thereby adjusting the sensitivity of triggering the warning light 3 and the alarm 4, which is convenient for flexible adjustment and use according to different lane environments.

[0027] The outer side of the measuring rod 2 and the inner side of the limiting plate 10 are both provided with threads 11, and the measuring rod 2 and the limiting plate 10 are movably connected through the threads 11. The limiting plate 10 is slidably installed on the inner side of the mounting groove 8, and the outer diameter of the limiting plate 10 is larger than the outer diameter of the spring 9. When in use, the spring 9 can cooperate with the limiting plate 10 to provide support for the measuring rod 2 to prevent the measuring rod 2 from falling under the action of its own weight and causing false triggering of the alarm. Moreover, the limiting plate 10 connected to the measuring rod 2 through the threads 11 can flexibly adjust the position of the limiting plate 10 on the measuring rod 2 during use, thereby adjusting the length of the measuring rod 2 that passes through the frame 1, so as to adapt to the uneven position of the inner wall of the tunnel.

[0028] The frame 1 is installed in the tunnel through a plurality of anchor rods 7. The arrangement of the anchor rods 7 can facilitate the frame 1 to be fixed inside the tunnel.

[0029] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
