[0017] 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.

[0018] Please see Figures 1-4 In this embodiment of the utility model, a tunnel lining maintenance device includes a movable box 1. The upper part of the top plate of the movable box 1 is provided with a downwardly recessed groove 2. A slider 4 is slidably connected to the inner wall of the groove 2. A sliding rod 5 is fixedly connected to the top of the slider 4. A fixed rod 3 is fixedly installed on the top of the movable box 1 on one side of the sliding rod 5. A mounting frame 6 is fixedly installed on the top of both the fixed rod 3 and the sliding rod 5. A water spray pipe 7 is fixedly installed on the inner wall of both mounting frames 6. A driving mechanism is installed on the outer wall of the groove 2. A rotating arm mechanism is connected to the output end of the driving mechanism. The rotating arm mechanism is used to drive the mounting frame 6 connected to the sliding rod 5 to move axially.

[0019] In this embodiment: First, the mobile box 1 is connected to the vehicle body (e.g., a water truck) by a towing hook (the mobile box 1 is fixedly installed with a docking ring that can be connected to the towing hook), and the water supply pipe of the water truck is connected to the input end of the spray pipe 7, so that the mobile box 1 can be moved by the water truck.

[0020] During the water spraying maintenance process, by starting the water pump and drive mechanism on the water truck, the drive mechanism drives the mounting bracket 6 at the top of the sliding rod 5 to move in the axial direction through the rotating arm mechanism. The mounting bracket 6 drives the sliding rod 5 to move synchronously, and the sliding rod 5 drives the slider 4 to slide axially in the slide groove 2. During this process, the mounting bracket 6 at the top of the fixed rod 3 and the water spray pipe 7 at the top of the mounting bracket 6 are in a stationary state.

[0021] It should be noted that the nozzles on the two water spray pipes 7 are staggered, so the water sprayed onto the lining surface is distributed more evenly.

[0022] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The drive mechanism includes a mounting plate 8 fixedly installed on the outer wall of the fixed rod 3. A forward and reverse motor 9 is fixedly installed on the top of the mounting plate 8. A drive gear 10 is fixedly installed on the output end of the forward and reverse motor 9. A driven gear 11 meshes with the outer periphery of the drive gear 10. A bidirectional screw 12 is interference-fitted onto the inner wall of the driven gear 11. A rotating frame 15 is fixedly installed on the outer wall of the fixed rod 3. The bidirectional screw 12 and the rotating frame 15 are rotatably connected by bearings. One end of the outer wall of the bidirectional screw 12 is provided with a positive thread, and the other end of the outer wall of the bidirectional screw 12 is provided with a negative thread.

[0023] In this embodiment: by starting the forward and reverse motor 9, the forward and reverse motor 9 drives the drive gear 10 to rotate, the drive gear 10 rotates and drives the driven gear 11 that meshes with it to rotate, and the rotating driven gear 11 drives the bidirectional screw 12 to rotate synchronously.

[0024] Please refer to this carefully. Figure 3 and Figure 4 The rotating arm mechanism includes two sliding components 14 connected to the positive and negative threads, respectively. A connecting frame 13 is fixedly installed at one end of the two sliding components 14 away from the bidirectional screw 12. A first rotating arm 16 and a second rotating arm 17 are rotatably installed on the inner side of the C-shaped part above the connecting frame 13. A rotating column 18 is rotatably installed at the other end of the first rotating arm 16 and the second rotating arm 17. The top end of the rotating column 18 is fixedly connected to the bottom end of the mounting frame 6. The sliding component 14 includes a fixed plate 1401 threadedly connected to the bidirectional screw 12. A connecting groove 1402 is opened inside the fixed plate 1401. A moving plate 1403 is slidably connected to the inner wall of the connecting groove 1402. A bracket 1404 that extends through to the outside of the fixed plate 1401 is fixedly connected to one end of the moving plate 1403. The bracket 1404 is fixedly connected to the lower inner side of the connecting frame 13.

[0025] In this embodiment: When the bidirectional screw 12 rotates, since the two fixing plates 1401 are connected to the positive and negative threads respectively, during the rotation of the bidirectional screw 12, the two fixing plates 1401 move closer or further away from each other. The two fixing plates 1401 pull the connecting frame 13 to move synchronously. At this time, a pushing or pulling force is applied to the first rotating arm 16 and the second rotating arm 17. Since the mounting bracket 6 located at the top of the fixing rod 3 cannot move, during the rotation of the first rotating arm 16 and the second rotating arm 17, the end of the two rotating arms moves axially synchronously, thereby driving the connecting frame 13 to move synchronously. The connecting frame 13 drives the bracket 1404 to move, and the moving bracket 1404 drives the moving plate 1403 to slide synchronously in the connecting groove 1402, avoiding interference.

[0026] By reciprocating the movement of a water spray pipe 7, more water can be sprayed onto the lining surface per unit time.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
