[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Embodiment 1
[0022] Please refer to Figures 1 to 5, the present utility model provides a technical solution: a deformation monitoring device for road tunnels, comprising: a support frame 1, a position changing mechanism 2 capable of adjusting the monitoring position is arranged between two support frames 1, a swinging mechanism 3 capable of swinging the monitoring position is arranged outside the position changing mechanism 2, and a monitoring mechanism 4 capable of monitoring the inner side of the tunnel is arranged outside the swinging mechanism 3. When in use, by providing the position changing mechanism 2, the monitoring mechanism 4 can be adjusted and moved according to the needs of use, so as to provide the needs for actual use and expand the monitoring range; by providing the swinging mechanism 3, the monitoring mechanism 4 can be swung, so that the monitoring mechanism 4 is located at the center position of the road tunnel, and then the monitoring mechanism 4 is swung and moved along the inner side of the road tunnel for monitoring. Therefore, the institutions provided above can make the monitoring range of the inner side of the road tunnel wider, and the monitoring mechanism 4 provided can ensure the hidden danger of convex deformation on the inner side of the road tunnel, thus providing convenience for people's use.
[0023] The position changing mechanism 2 includes a first fixing plate 21 fixedly connected between two support frames 1. A first sliding groove 22 is opened inside the first fixing plate 21. A first motor 23 is fixedly connected to the bottom of the inner wall of the first sliding groove 22. The output end of the first motor 23 is fixedly connected to a first reciprocating lead screw 25. A first movable plate 24 is threadedly connected to the outside of the first reciprocating lead screw 25 and located outside the first fixing plate 21. When in use, the operation control panel 7 controls the first motor 23 to run and rotate the first reciprocating lead screw 25, so that the rotating first reciprocating lead screw 25 drives the first movable plate 24 to slide outside the first fixing plate 21, and then the monitoring mechanism 4 can be moved to the required monitoring position.
[0024] The swinging mechanism 3 includes a second motor 32 fixedly connected to the top of the first movable plate 24. The output end of the second motor 32 is fixedly connected to a second reciprocating lead screw 33. A rack 34 is threadedly connected to the outside of the second reciprocating lead screw 33. A gear 37 is meshed and connected to the top of the rack 34. A rotating shaft 31 is fixedly connected to the inside of the gear 37. Both ends of the rotating shaft 31 are rotatably connected to fixing blocks 38. Both fixing blocks 38 are fixedly connected to the first movable plate 24. When in use, when swinging and monitoring the inner side of the road tunnel, the second motor 32 is controlled to run and rotate the second reciprocating lead screw 33, so that the rotating second reciprocating lead screw 33 drives the rack 34 to move reciprocally, and the reciprocating movement drives the gear 37 to rotate clockwise and counterclockwise reciprocally. Therefore, when the gear 37 drives the rotating shaft 31 to rotate clockwise and counterclockwise reciprocally in the fixing blocks 38.
[0025] The monitoring mechanism 4 includes a swing plate 41 fixedly connected to the outer side of the rotating shaft 31. A second sliding groove 42 is formed inside the swing plate 41. A first slider 43 is slidably connected to the inner wall of the second sliding groove 42. Two first springs 44 are fixedly connected between the bottom of the inner wall of the second sliding groove 42 and the bottom of the first slider 43. A touch switch 45 is fixedly connected to the bottom of the inner wall of the second sliding groove 42 and located between the two first springs 44. Two connecting rods 46 are fixedly connected to the top of the first slider 43. A fixed seat 47 is arranged at the top of the connecting rod 46. A rolling ball 48 is arranged inside the fixed seat 47. During use, when the swing plate 41 is driven to swing, it will drive the rolling ball 48 to roll inside the road tunnel. When the rolling ball 48 encounters a deformed convex position inside the road tunnel, it will push the fixed seat 47 outside the rolling ball 48 to move, so that the fixed seat 47 drives the first slider 43 to slide inside the second sliding groove 42 through the two connecting rods 46. The moving first slider 43 can compress the first spring 44. When the first slider 43 touches the touch switch 45, a signal is fed back to the control panel 7 through the operation of the touch switch 45.
[0026] Embodiment 2
[0027] As Figures 1 to 4 shown, in the second embodiment, other structures remain unchanged. Different from the first embodiment, two limiting rods 26 are slidably connected inside the first movable plate 24. The two limiting rods 26 are fixedly connected to the support frame 1. When the first movable plate 24 moves, it will slide on the outer sides of the two limiting rods 26. The limiting rods 26 can provide a guiding and limiting force for the first movable plate 24. A limiting plate 35 is fixedly connected to the bottom of the rack 34. A limiting groove 36 matching the limiting plate 35 is formed at the top of the first movable plate 24. By arranging the limiting plate 35 at the bottom of the rack 34, the limiting plate 35 can slide in the limiting groove 36, so as to provide a guiding and limiting force when the rack 34 moves. An alarm 6 is fixedly connected to one side of the support frame 1. A control panel 7 is fixedly connected to one side of the support frame 1. The control panel 7 is electrically connected to the first motor 23, the second motor 32, the touch switch 45 and the alarm 6. By arranging the control panel 7, the operation of the first motor 23, the second motor 32, the touch switch 45 and the alarm 6 can be controlled. Therefore, when the touch switch 45 feeds back information to the control panel 7, the control panel 7 can control the operation of the alarm 6 to monitor and give early warning to the staff. Two mounting mechanisms 5 capable of fixing the position are arranged at the top of the support frame 1. The two mounting mechanisms 5 include mounting frames 51 fixedly connected to the top of the support frame 1. Two bolts 52 are threadedly connected inside the mounting frames 51. By using the bolts 52, the mounting frames 51 can be installed inside the road tunnel, so as to place the device at the center of the road tunnel.
