[0003] The existing audible and visual alarm device for preventing voids in the arch is fixed to the support rod in actual use. However, in practice, the alarm device needs to be aligned with the grouting pipe to detect the grout level in the vicinity of the grouting pipe. This can only be achieved by cutting and welding the support rod, which is time-consuming, labor-intensive, and extremely troublesome. At the same time, the top detection head needs to be flush with the top of the grouting pipe. However, due to the installation method, the top of the device may not be flush with the top of the grouting pipe. In this case, the entire device needs to be disassembled and reinstalled.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The audible and visual alarm device for preventing voids in the arch of the tunnel secondary lining concrete pouring works by rotating a rotating head, which in turn drives a gear to rotate, which in turn drives a rack to rotate, which in turn drives a pressure plate and friction block to move upward, causing the pressure plate and friction block to separate from the top of the fixed rail, thus eliminating friction between the friction block and the fixed rail. At this point, by moving a sliding seat, the sliding seat drives the support seat and the main body of the monitor to move, thereby adjusting the position of the support seat and the main body of the monitor, which facilitates the alignment between the main body of the monitor and the grouting pipe.

[0013] 2. The anti-vacuum audible and visual alarm device for the concrete pouring arch of the tunnel secondary lining works by rotating the rotating seat, which in turn causes the rotating plate and spring two to rotate. This causes the spring two to rotate on the inner wall teeth of the inner ratchet ring. At the same time, the rotating seat causes the threaded column at the top to rotate, which in turn causes the threaded column to move up and down through the threaded connection with the threaded sleeve. This, in turn, causes the threaded sleeve to move up and down, making the height of the monitor body at the top adjustable. When the height of the monitor body is adjusted, the rotating seat stops rotating. At this time, the locking relationship between spring two and the inner ratchet ring prevents the rotating seat from rotating in the opposite direction. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 5 A sound and light alarm device for preventing voids in the arch of the tunnel secondary lining concrete pouring includes a fixed rail 1, a support seat 2 on the outer wall of the fixed rail 1, a grouting pipe 3 on the outer wall of the support seat 2, a sliding seat 4 fixedly installed on the outer wall of the support seat 2, a rotating head 6 rotatably connected to the inner wall of the sliding seat 4, a gear 5 fixedly installed on the outer wall of the rotating head 6, a pressure plate 7 slidably connected to the inner wall of the sliding seat 4, a rack 8 fixedly installed on the top of the pressure plate 7, a sealing plug 21 on the outer wall of the sliding seat 4, a friction block 9 fixedly installed on the bottom of the pressure plate 7, a limit post 10 fixedly installed on the top of the pressure plate 7, and a sealing plug 21 on the outer wall of the sliding seat 4. A fixed plate 11 is fixedly installed. A spring 12 is provided on the inner wall of the sliding seat 4. A monitor body 13 is slidably connected to the inner wall of the support seat 2. A threaded sleeve 14 is fixedly installed at the bottom of the monitor body 13. A limit block 15 is fixedly installed on the outer wall of the threaded sleeve 14. A limit groove 16 is opened on the inner wall of the support seat 2. A rotating seat 17 is rotatably connected to the bottom of the support seat 2. A threaded column 22 is fixedly installed on the top of the rotating seat 17. An inner ratchet ring 18 is fixedly installed on the inner wall of the support seat 2. A rotating plate 19 is provided on the inner wall of the rotating seat 17. A spring 20 is rotatably connected to the inner wall of the rotating seat 17.

[0022] In the above structure, the limiting block 15 is located on the inner wall of the limiting groove 16, so that the limiting groove 16 limits the limiting block 15, and thus the limiting block 15 can only slide on the inner wall of the limiting groove 16 when it moves, thereby limiting the threaded sleeve 14 so that the threaded sleeve 14 will not rotate when it moves.

[0023] In a preferred embodiment, the gear 5 is located outside the rack 8 and meshes with the outer wall of the rack 8.

[0024] In the above structure, by rotating the gear 5, the gear 5 meshes with the rack 8, causing the rack 8 to move, which in turn causes the rack 8 to move the bottom pressure plate 7, which in turn causes the pressure plate 7 to move the friction block 9 and the limiting post 10, which in turn causes the spring 12 to contract, so that the height of the friction block 9 can be controlled by rotating the gear 5.

[0025] In a preferred embodiment: the limiting post 10 passes through the fixing plate 11, and the limiting post 10 and the fixing plate 11 are slidably connected.

[0026] In the above structure, the sliding connection between the limiting post 10 and the fixed plate 11 ensures that the limiting post 10 can only slide on the inner wall of the fixed plate 11 when it moves, so that the limiting post 10 will not tilt when it moves, and the pressure plate 7 at the bottom of the limiting post 10 will not tilt when it moves.

[0027] In a preferred embodiment, the shape of the friction block 9 is adapted to the top shape of the fixed rail 1, and the fixed rail 1 is located on the inner wall of the sliding seat 4, with the sliding seat 4 located below the friction block 9.

[0028] In the above structure, the spring 12 presses the pressure plate 7 downward, which in turn causes the pressure plate 7 to drive the friction block 9 downward, so that the friction block 9 is in contact with the top of the fixed rail 1, thereby generating friction between the friction block 9 and the outer wall of the fixed rail 1, fixing the friction block 9 to the outside of the fixed rail 1, and thus fixing the positions of the sliding seat 4 and the support seat 2.

[0029] In a preferred embodiment, the threaded post 22 is located on the inner wall of the threaded sleeve 14, and the threaded post 22 and the threaded sleeve 14 are threadedly connected.

[0030] In the above structure, by rotating the rotating seat 17, the rotating seat 17 drives the threaded post 22 at the top to rotate, so that the threaded post 22 moves up and down on the inner wall of the support seat 2 through the threaded connection with the threaded sleeve 14, thereby causing the monitor body 13 at the top of the threaded sleeve 14 to move up and down. Thus, the height of the monitor body 13 can be controlled by rotating the rotating seat 17.

[0031] In a preferred embodiment, the shape of the second spring 20 is adapted to the shape of the teeth of the inner ratchet ring 18, and the second spring 20 is located in the teeth of the inner ratchet ring 18.

[0032] In the above structure, when the rotating seat 17 is rotated counterclockwise, the rotating seat 17 drives the rotating plate 19 and the second spring 20 to produce a circular motion. At the same time, the second spring 20 rotates along the inner wall of the inner ratchet ring 18, so that the second spring 20 and the teeth of the inner ratchet ring 18 are always in contact. When the rotation stops, the second spring 20 prevents the rotating seat 17 from rotating in the opposite direction because of the contact between the second spring 20 and the teeth of the inner ratchet ring 18.

[0033] Working principle: When using the equipment, first, the sliding seat 4 is fitted onto the outer wall of the fixed rail 1, and then the fixed rail 1 is fixed. At this time, by rotating the gear 5, the gear 5 drives the rack 8 to move, which in turn drives the pressure plate 7 to move. The pressure plate 7 drives the friction block 9 at the bottom to move upward, thus separating the friction block 9 from the top of the fixed rail 1. At this time, the fixed relationship of the sliding seat 4 disappears. Then, by moving the sliding seat 4 on the outer wall of the fixed rail 1, the position of the support seat 2 and the monitor body 13 is adjusted. When the monitor body 13 moves to the outside of the grouting pipe 3 and is aligned, the gear 5 is released, so that the rotational force of the gear 5 disappears, and the spring 12 rebounds. The rebound of the spring 12 pushes the pressure plate 7 and the friction block 9 downward, so that the friction block 9 is in contact with the top of the fixed rail 1. At this time, the friction block 9 and the fixed rail 1 generate friction. The friction force fixes the friction block 9. When the rotating seat 17 is rotated, the rotating seat 17 drives the rotating plate 19 and the second spring 20 to produce a circular motion. At the same time, the second spring 20 rotates along the inner wall of the inner ratchet ring 18, so that the teeth of the second spring 20 and the inner ratchet ring 18 are always in contact. Meanwhile, the rotating seat 17 drives the top threaded post 22 to rotate, so that the threaded post 22 drives the threaded sleeve 14 to move through the threaded connection with the threaded sleeve 14. This causes the threaded sleeve 14 to move the monitor body 13 upward, so that the top of the monitor body 13 is flush with the top of the grouting pipe 3. At this time, the rotating seat 17 stops rotating. The second spring 20, through its contact with the teeth of the inner ratchet ring 18, prevents the rotating seat 17 from rotating in the opposite direction. At this time, mud can be injected into the interior of the fixed rail 1, and the height of the mud outside the grouting pipe 3 can be detected by the monitor body 13.
