Technical Field

[0001] The utility model relates to the technical field of tunnel deformation detection, in particular to a tunnel deformation detection device. Background Art

[0002] Tunnels are advanced transportation facilities used by roads and railways when they pass through special terrains such as mountains and riverbeds. Their emergence solves the problem of vehicles having to take detours due to the obstruction of mountains and rivers. During the use of tunnels, the passage of vehicles or geological movements will inevitably cause stress to certain parts of the tunnel, causing it to deform. If these deformed parts are not handled in time, they will cause serious damage to the tunnel structure over the years, causing it to break or even collapse.

[0003] However, in the existing technology, the existing tunnel detection methods mostly rely on personnel to use handheld detection equipment to detect the flatness of the tunnel wall. This method leads to an increase in the workload of the staff. At the same time, since the staff operate the instrument handheld, it cannot be guaranteed that the instrument always fits the tunnel wall. Therefore, there is a large error in the detection of the flatness of the tunnel wall, and the work efficiency is slow.

[0004] Therefore, we need a tunnel deformation detection device to solve the problem of detecting the deformation of the inner wall of the tunnel by the existing manual handheld detection instrument, and also to detect the deformation of the inner wall of the tunnel to avoid missed detection.

[0009] Preferably, the surface of the vertical plate is fixedly connected to the base of the motor, the end of the power output shaft of the motor is fixedly connected to the surface of the driving gear, the teeth of the driving gear mesh with the teeth of the driven gear, the through hole surface of the driven gear is fixedly connected to the surface of the limiting shaft, the end bearing seat of the limiting shaft is fixed to the surface of the vertical plate, the surfaces of the driven gear and the driving gear are both fixedly connected to the toggle rod, and the cross-sectional surface of the limiting shaft is set in a "T" shape.

When the interior of the tunnel body 1 is deformed and collapsed, the contraction rod 7 is compressed inside the cavity rod 6, so that the bottom end of the hard rubber rod 11 is compressed on the top surface of the pressure sensor 13, so that the pressure sensor 13 can read whether the deformation pressure value of the inner wall of the tunnel body 1 is within the normal range. Therefore, the deformation of the inner wall of the tunnel body 1 can be detected according to the contraction position of the contraction rod 7 in the cavity rod 6, and there is no need to manually hold a detection instrument to detect the tunnel.

[0020] Embodiment 2

[0021] See attached Figures 1 to 3On the basis of the first embodiment, in order to avoid missing the inner wall of the tunnel body 1, the bottom surface of the vertical plate 3 is fixedly connected with the dragging and moving plate 2, the dragging and moving plate 2 is arranged inside the tunnel body 1, the inside of the vertical plate 3 is fixedly connected with the bearing surface of the driving shaft 14, the surface of the driving shaft 14 is fixed inside the reset gear 15, and the end of the driving shaft 14 is fixed to the surface of the cam 5;

[0022] By fixing the inside of the reset gear 15 to the surface of the drive shaft 14 and then fixing the end of the drive shaft 14 to the inner wall of the cam 5, when the reset gear 15 rotates on the surface of the vertical plate 3, the cam 5 can drive the cavity rod 6 to rotate, so that the top end of the roller 10 will always be against the inner wall of the tunnel body 1, avoiding missing the inner wall of the tunnel body 1.

[0023] Embodiment 3

[0024] Refer to the attached Figures 1 to 3 On the basis of the second embodiment, in order to realize the forward and reverse rotation of the reset gear 15 on the surface of the vertical plate 3, the surface of the vertical plate 3 is fixedly connected to the base of the motor 4, the end of the power output shaft of the motor 4 is fixedly connected to the surface of the driving gear 19, the teeth of the driving gear 19 mesh with the teeth of the driven gear 16, the through hole surface of the driven gear 16 is fixedly connected to the surface of the limiting shaft 17, the end bearing seat of the limiting shaft 17 is fixed to the surface of the vertical plate 3, the surfaces of the driven gear 16 and the driving gear 19 are fixedly connected to the toggle rod 18, and the cross-section of the limiting shaft 17 is set in a "T" shape;

[0025] By starting the motor 4, the driving gear 19 can mesh with the driven gear 16 and rotate on the surface of the vertical plate 3. By arranging a toggle lever 18 on the surfaces of the driven gear 16 and the driving gear 19, the tooth surface of the reset gear 15 can be toggled by the toggle lever 18, so that the reset gear 15 automatically rotates on the surface of the vertical plate 3. The toggle lever 18 on the surfaces of the driven gear 16 and the driving gear 19 is staggered, so the reset gear 15 can realize forward and reverse rotation on the surface of the vertical plate 3. Therefore, the forward and reverse swing roller 10 of the cavity rod 6 can realize forward and reverse rolling along the inner wall of the tunnel body 1. When the retracting rod 7 presses the surface of the pressure sensor 13 to detect that the inner wall of the tunnel body 1 exceeds the normal collapse range value, an alarm reminder is generated by the flashing of the motor 4.

[0026] In actual use, the surface of the retractable rod 7 is movably connected to the surface of the cavity rod 6, and then the bottom end of the retractable rod 7 is fixed to the top end of the hard rubber rod 11, and the surface of the roller 10 is pressed against the inner wall of the tunnel body 1. When the interior of the tunnel body 1 is deformed and collapsed, the retractable rod 7 is compressed inside the cavity rod 6, so that the bottom end of the hard rubber rod 11 is compressed on the top surface of the pressure sensor 13, so that the pressure sensor 13 can read whether the deformation pressure value of the inner wall of the tunnel body 1 is within the normal range. Therefore, according to the retracted position of the retractable rod 7 in the cavity rod 6, the deformation of the inner wall of the tunnel body 1 is detected, and at the same time, there is no need to manually hold the detection instrument to detect the tunnel. The inside of the reset gear 15 is fixedly connected to the surface of the drive shaft 14, and then the end of the drive shaft 14 is fixed to the inner wall of the cam 5. When the reset gear 15 rotates on the surface of the vertical plate 3, it can make The cam 5 drives the cavity rod 6 to rotate, so the top of the roller 10 will always be against the inner wall of the tunnel body 1, avoiding missing the inner wall of the tunnel body 1. By starting the motor 4, the driving gear 19 can mesh with the driven gear 16 to rotate on the surface of the vertical plate 3. By arranging a toggle rod 18 on the surfaces of the driven gear 16 and the driving gear 19, the tooth surface of the reset gear 15 is toggled by the toggle rod 18, so that the reset gear 15 automatically rotates on the surface of the vertical plate 3. The toggle rod 18 on the surfaces of the driven gear 16 and the driving gear 19 is staggered, so the reset gear 15 can achieve positive and negative rotation on the surface of the vertical plate 3. Therefore, the cavity rod 6 can be swung forward and backward, and the roller 10 can be rolled forward and backward along the inner wall of the tunnel body 1. When the retracting rod 7 presses the surface of the pressure sensor 13 to detect that the inner wall of the tunnel body 1 exceeds the normal collapse range, an alarm reminder is generated by flashing the motor 4.
