[0032] 3. In this solution, the transmission mechanism also drives the synchronous movement of the connecting frame. The scraper can remove stubborn dirt on the inner wall of the tunnel segment, further improving the cleaning effect of the tunnel segment and making it highly practical. Moreover, the telescopic performance of the scraper and the inner column makes the scraper fit better, improving the scraping effect of the scraper, while avoiding hard contact between the scraper and the segment, reducing the wear of the scraper and increasing its service life.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figures 1-11 A tunnel segment cleaning device, comprising:

[0048] The cleaning vehicle 1 is equipped with a water tank 2 and multiple figure-eight wheels 3, each of which is driven by a drive mechanism.

[0049] The circular arc track 4 is installed on the cleaning vehicle body 1, and the circular arc track 4 and the tunnel segment are concentric circles. A connecting frame 5 is slidably installed on the circular arc track 4.

[0050] The transmission mechanism 6 is connected to the connecting frame 5 and is used to drive the connecting frame 5 to reciprocate along the circumference of the arc track 4.

[0051] The cleaning mechanism 7, mounted on the connecting frame 5, is used to clean the inner wall of the tunnel segment.

[0052] In use, after the tunnel segments are assembled inside the tunnel and the temporary transport rails inside the tunnel are removed, the device is moved into the tunnel. At this time, the figure-eight wheels 3 of the cleaning vehicle 1 contact the tunnel wall and are driven by the drive mechanism to move, thus moving the cleaning vehicle 1 inside the tunnel. After moving to the cleaning position, the corresponding position on the inner wall of the tunnel segment can be cleaned by the cleaning mechanism 7 on the connecting frame 5. The transmission mechanism 6 drives the connecting frame 5 to move in a circle along the arc track 4, and the connecting frame 5 moves in a circle with the cleaning mechanism 7. Thus, different positions of the tunnel segment can be cleaned by the cleaning mechanism 7, which can efficiently and comprehensively clean the tunnel segment. This avoids the current method of manual washing before segment assembly. Cleaning the assembled tunnel segment can effectively improve its cleaning quality and effect, thereby improving the overall construction quality. It can also greatly reduce the manpower and water resources wasted by manual washing, reduce costs and significantly improve construction efficiency. It has high practicality and can be widely promoted and used.

[0053] The connecting frame 5 is equipped with a telescopic component 26, the telescopic end of which is connected to the adapter seat 71. The connecting frame 5 is provided with a protective shell that covers the telescopic component 26. The telescopic component 26 in this application can be a cylinder or an electric telescopic rod. When the device is placed in the tunnel, the telescopic component 26 can drive the connecting frame 5 and the cleaning mechanism 7 on it to move, thereby changing the extension length of the cleaning mechanism 7. The height of the cleaning mechanism 7 can be adjusted according to the excavation diameter of the tunnel, making it suitable for cleaning tunnel segments of various specifications and sizes. It has a wide range of applications and high flexibility.

[0054] In this embodiment, preferably, please refer to [reference needed]. Figure 2 and Figures 5-6The outer wall of the arc track 4 is provided with an arc groove 8, and the connecting frame 5 is rotatably equipped with a pulley 9 that slides and adapts to the arc groove 8. When the connecting frame 5 is driven by the transmission mechanism 6 to move in a circle along the arc track 4, the pulley 9 of the connecting frame 5 will roll along the arc groove 8. The position of the connecting frame 5 can be restricted by the pulley 9 and the arc groove 8, thereby improving its movement stability.

[0055] In this embodiment, preferably, please refer to [reference needed]. Figure 2 and Figure 5 The transmission mechanism 6 includes:

[0056] Chain 61 is circumferentially distributed on the outer wall of the circular arc track 4;

[0057] The drive unit 62 is mounted on the connecting frame 5, and the output end of the drive unit 62 is provided with a drive sprocket 63 that meshes with the chain 61.

[0058] The drive component 62 in this application is a servo motor. The drive component 62 is mounted on the connecting frame 5, which is slidably mounted on the arc track 4. When the drive component 62 drives the drive sprocket 63 to rotate, the meshing of the drive sprocket 63 and the chain 61 causes the drive component 62 to carry the connecting frame 5 to move in a circle along the arc track 4, thereby causing the cleaning mechanism 7 on the connecting frame 5 to move in a circle.

[0059] In this embodiment, preferably, please refer to [reference needed]. Figures 1-3 and Figure 5 The cleaning unit 7 includes:

[0060] The adapter 71 is provided with a detachable roller brush 72 and a first water pipe 73 connected to the water storage tank 2 via a hose.

[0061] The adapter 71 has a built-in motor for driving the roller brush 72 to rotate;

[0062] Multiple high-pressure nozzles 74 are installed on the first water pipe 73.

[0063] A booster pump is installed in the water storage tank 2. Water or water containing cleaning solution in the water storage tank 2 is introduced into the first water pipe 73 through a hose. Then, the high-pressure nozzle 74 sprays the water onto the tunnel segments, which can achieve the effect of rinsing and cleaning the segments. At the same time, the roller brush 72 contacts the segments, and the motor built into the adapter 71 drives the roller brush 72 to rotate. The rotation of the roller brush 72 can further clean the dirt on the segments. The high-pressure nozzle 74 and the roller brush 72 can effectively clean the tunnel segments, thus improving the cleaning quality of the segments.

[0064] In this embodiment, preferably, please refer to [reference needed]. Figures 3-5 and Figures 7-10A rotating shaft 10 is rotatably mounted on the adapter 71. The rotating shaft 10 is connected to the motor inside the adapter 71. A socket 11 is slidably fitted on the outer wall of the rotating shaft 10. A mounting post 12 is provided at the end of the roller brush 72. A socket 13 adapted to the socket 11 is opened at the end of the mounting post 12. A mounting component 14 is provided on the socket 11 for connecting the socket 11 and the mounting post 12.

[0065] When installing the roller brush 72, first slide the socket 11 along the pivot 10 to increase the distance between the two sockets 11. Then place the roller brush 72 between the two sockets 11, aligning the socket 11 with the insertion hole 13 of the mounting post 12 on the roller brush 72. Gradually release the socket 11, and it will insert into the insertion hole 13. Finally, the mounting component 14 connects the socket 11 and the mounting post 12, completing the installation of the roller brush 72. Disassembly is similar; the mounting component 14 disconnects the socket 11 from the mounting post 12, and then the socket 11 slides along the pivot 10, disengaging it from the insertion hole 13 of the mounting post 12. The roller brush 72 can then be removed. This detachable design of the roller brush 72 allows for simple and quick installation and removal, facilitating cleaning or replacement, saving time and effort, ensuring sufficient cleaning performance, and providing high flexibility.

[0066] In this embodiment, preferably, please refer to [reference needed]. Figures 8-9 The socket 11 has a sliding cavity 15 that is slidably connected to the rotating shaft 10. A first elastic element 16 is connected between the inner wall of the sliding cavity 15 and the end of the rotating shaft 10. A stop groove 17 is formed in the inner wall of the sliding cavity 15, and a stop block 18 connected to the rotating shaft 10 is slidably disposed in the stop groove 17. The first elastic element 16 in this application can be a spring. When the socket 11 slides along the rotating shaft 10, the stop block 18 will slide along the stop groove 17 and compress the first elastic element 16. When the socket 11 is released, the first elastic element 16 can drive the socket 11 to return to its original position. At the same time, the stop block 18 can limit the socket 11 and prevent the socket 11 from disengaging from the rotating shaft 10.

[0067] In this embodiment, preferably, please refer to [reference needed]. Figures 8-10 A limiting groove 19 is formed on the inner wall of the socket 13, and the mounting assembly 14 includes:

[0068] An inner recess 141 is formed inside the socket 11. A limiting block 142 is slidably connected to the inner wall of the inner recess 141. A second elastic member 143 is connected between the inner end of the limiting block 142 and the inner wall of the inner recess 141.

[0069] Release component 144 is used to drive limit block 142 to move inward toward the interior of inner recess 141.

[0070] The second elastic element 143 in this application can be a spring. When the socket 11 is inserted into the socket 13, the limiting block 142 will be squeezed by the inner wall of the socket 13. The limiting block 142 will gradually move into the inner recess 141 and compress the second elastic element 143. When the socket 11 is inserted into the bottom wall of the socket 13, the limiting block 142 is in the position of the limiting groove 19. After the limiting block 142 is no longer compressed, the second elastic element 143 can drive the limiting block 142 to reset. At this time, the limiting block 142 will enter the limiting groove 19, and the connection between the socket 11 and the mounting post 12 can be realized.

[0071] Then, by releasing component 144, the limiting block 142 can be gradually moved into the inner recess 141, and the limiting block 142 will disengage from the limiting groove 19. After that, the socket 11 can be moved to disengage from the socket 13, thus completing the separation of the socket 11 and the mounting post 12.

[0072] In this embodiment, preferably, please refer to [reference needed]. Figures 8-10 The release component 144 includes a sliding groove 1441 formed on the outer wall of the socket 11. A push rod 1442 is slidably connected to the inner wall of the sliding groove 1441. One end of the push rod 1442 is provided with a traction rope 1443, and the other end of the traction rope 1443 is connected to the inner end of the limiting block 142.

[0073] By pushing the push rod 1442 along the sliding groove 1441, the push rod 1442 will pull the traction rope 1443, and the other end of the traction rope 1443 will pull the limiting block 142 to move it into the inner recess 141, thus disengaging the limiting block 142 from the limiting groove 19. After releasing the push rod 1442, the second elastic element 143 will cause the limiting block 142 to reset, and the limiting block 142 will pull the traction rope 1443, ultimately causing the push rod 1442 to reset as well.

[0074] The socket 11 has an internal channel 32 that communicates with the inner recess 141 and the sliding groove 1441. Multiple support rods 33 are installed within the channel 32, and rotatable guide wheels 34 are mounted on the support rods 33. The traction rope 1443 on the push rod 1442 passes through the multiple guide wheels 34 and connects to the limiting block 142. The guide wheels 34 allow the traction rope 1443 to be turned, resulting in better force distribution on the limiting block 142, improved smoothness of movement, reduced friction on the traction rope 1443, and extended service life of the traction rope 1443.

[0075] In this embodiment, preferably, please refer to [reference needed]. Figures 3-4The adapter 71 is equipped with a guide rail 20, on which a guide seat 21 connected to the first water pipe 73 is slidably connected. The guide rail 20 has multiple fixing holes 22, and the guide seat 21 is threaded with bolts 23 that fit the fixing holes 22. Loosening the bolts 23 allows the guide seat 21 to slide up and down along the guide rail 20, which in turn moves the first water pipe 73 up and down. This changes the distance between the high-pressure nozzle 74 on the first water pipe 73 and the tunnel segment. The position of the high-pressure nozzle 74 can be adjusted according to actual needs and flushing effect, offering wide applicability, high flexibility, and effectively improving the cleaning effect of the tunnel segment. After adjustment, the bolts 23 are tightened to enter the corresponding fixing holes 22, thus fixing the guide seat 21 to the guide rail 20.

[0076] In this embodiment, preferably, please refer to [reference needed]. Figures 1-2 The cleaning vehicle body 1 is equipped with a support frame 24 connected to the arc track 4. A second water pipe 25 is installed at the bottom of the support frame 24. The second water pipe 25 is connected to the water storage tank 2 via a hose and is equipped with a nozzle. The booster pump in the water storage tank 2 also supplies water through the hose to the second water pipe 25, and the nozzle on it cleans the tunnel segments at the bottom of the tunnel. This can clean the blind spots of the cleaning mechanism 7, improve the cleaning effect of the tunnel segments, and eliminate the need for subsequent manual cleaning, saving time and labor.

[0077] For preferred options, please refer to [link / reference]. Figures 1-3 , Figure 5 and Figure 11 The adapter 71 is provided with a connecting rod 27, and the connecting rod 27 is provided with a scraper 28.

[0078] When the transmission mechanism 6 drives the connecting frame 5 and the cleaning mechanism 7 to move in a circular motion along the arc track 4, it will also drive the scraper 28 to move synchronously. The scraper 28 can scrape off the stubborn dirt attached to the inner wall of the tunnel segment, further improving the cleaning effect of the tunnel segment and making it highly practical.

[0079] For preferred options, please refer to [link / reference]. Figure 3 , Figure 5 and Figure 11The adapter 71 is provided with an outer column 29, and an inner column 30 connected to a connecting rod 27 is slidably inserted inside the outer column 29. A third elastic element 31 is provided at the inner end of the inner column 30 and on the inner wall of the outer column 29. The third elastic element 31 in this application can be a spring or a damper. Before the roller brush 72 of the cleaning mechanism 7, driven by the telescopic member 26, contacts the tunnel segment, the scraper 28 will first contact the tunnel segment. Then, as it continues to move until the roller brush 72 contacts the tunnel segment, the scraper 28 will be compressed, causing the inner column 30 to move towards the outer column 29, compressing the third elastic element 31. This improves the fit of the scraper 28 and enhances its scraping effect. Simultaneously, it avoids hard contact between the scraper 28 and the tunnel segment, reducing wear and extending its service life. Furthermore, the scraper 28, through the telescopic movement of the inner column 30, can accommodate various tunnel and tunnel segment diameters, offering high flexibility.
