Detailed implementation manners

[0030] Next, the present invention will be specifically described through exemplary implementation manners. However, it should be understood that, without further description, the elements, structures and features in one implementation manner can also be beneficially combined with those in other implementation manners.

[0031] It should be noted that: unless otherwise defined, the technical terms or scientific terms used herein should have the ordinary meaning understood by those with ordinary skills in the field to which the present invention belongs. The words such as "a", "one" or "the" used in the specification and claims of the present invention patent application do not express a quantity limitation, but indicate the existence of at least one; the "first", "second" and "third" used herein should not be regarded as a limitation on the order of components, but only to distinguish different components; the words such as "comprising" or "including" point out that the elements or objects appearing before "comprising" or "including" cover the elements or objects listed after "comprising" or "including" and their equivalents, but do not exclude other elements or objects with the same functions.

[0032] To more clearly describe the specific structural composition of the integrated tunnel flushing and grinding vehicle, reference is made to the attached Figures 1-4 to describe this embodiment:

[0033] As Figure 1 and Figure 2 shown, an integrated tunnel flushing and grinding vehicle includes a vehicle body 1. A water distribution plate 2 is rotatably arranged at the head of the vehicle body 1. The vehicle body 1 is also provided with a driving component for driving the water distribution plate 2 to rotate reciprocally and a water supply component for supplying water into the water distribution plate 2; telescopic pipes 3 communicating with the internal water channels are installed on the circumferential surface of the water distribution plate 2. Nozzles 4 are arranged at the ends of the telescopic pipes 3 far away from the water distribution plate 2. After the telescopic pipes 3 accumulate water pressure, they elongate and drive the nozzles 4 to extend outwards. An installation frame 5 is fixed at the end of the telescopic pipe 3 where the nozzle 4 is located. Grinding members 6 that move radially along with the nozzle 4 and can contact the inner wall of the tunnel are arranged on the installation frame 5. The grinding parts of the grinding members 6 are located outside the nozzles 4. Water enters the telescopic pipes 3 through the water distribution plate 2. When the water pressure in the telescopic pipes 3 is sufficient, the nozzles 4 and the grinding members 6 are pushed outwards. The grinding members 6 contact the tunnel wall first, and the nozzles 4 do not need to contact the tunnel wall. The water distribution plate 2 rotates reciprocally, enabling the grinding members 6 to clean the annular cross-section of the tunnel wall. As the vehicle 1 moves, the entire inner wall of the tunnel can be cleaned;

[0034] The length of the telescopic pipe 3 is adjustable. The elongation of the telescopic pipe is achieved by using the internal water pressure, and no other power mechanisms need to be set. At the same time, the grinding members can also retract adaptively along with the telescopic pipe to ensure the flexible fit of the grinding members 6 with the tunnel wall; the telescopic pipe 3 rotates reciprocally along with the water distribution plate 2, thereby achieving full contact and coverage of the tunnel surface; the nozzles 4 and the grinding members 6 are arranged in a supporting manner and can perform flushing and grinding synchronously, improving the efficiency.

[0035] The grinding member 6 can specifically be a grinding wheel or a plate made of other related materials. The grinding part in direct contact with the tunnel wall has friction protrusions and can be directly fixed on the installation frame 5.

[0036] Referring to Figure 3 and Figure 4 in the above embodiment, the telescopic pipe 3 specifically includes a fixed pipe 301, a movable pipe 302, a piston plate 303, and a connection hole 304; one end of the fixed pipe 301 is fixed to the interface of the water distribution plate 2, and the other end slidably arranges the movable pipe 302. One end of the movable pipe 302 is fixed with a piston plate 303. The piston plate 303 slides in the inner cavity of the fixed pipe 301. The inner cavities of the fixed pipe 301 and the movable pipe 302 are communicated through the connection hole 304 provided on the piston plate 303. The other end of the movable pipe 302 is connected to the nozzle 4;

[0037] The elongation of the telescopic pipe 3 is achieved by the displacement of the movable pipe 302. When the water pressure enters the fixed pipe 301 from the water distribution plate 2, on the one hand, it acts on the edge of the piston plate 303, pushing the piston plate 303 and the movable pipe 302 to move outward. On the other hand, the water enters the inner cavity of the movable pipe 302 through the connection hole 304 and is sprayed out from the nozzle 4.

[0038] Refer to Figure 3 , in the above embodiment, a steel ball roller 7 is fixed on the mounting bracket 5. The steel ball roller 7 and the grinding member 6 are in contact with the inner wall of the tunnel at the same time. The steel balls share a certain pressure for the grinding wheel, avoiding excessive force on the grinding member and improving the running stability.

[0039] Refer to Figure 3 and Figure 4 , in the above embodiment, a guide seat 8 is installed on the fixed pipe 301. A guide rod 9 parallel to the fixed pipe 301 is slidably arranged in the guide hole of the guide seat 8. One end of the guide rod 9 is fixedly connected to the corresponding mounting bracket 5; the guide rod 9 is arranged in parallel with the telescopic pipe 3 and can limit the angle of the mounting bracket 5 and the grinding member 6, avoiding the running jamming caused by its own rotation;

[0040] To facilitate the storage of the telescopic pipe 3, in the non - use state, most of the movable pipe 302 retracts into the fixed pipe 301, making the length of the entire telescopic pipe 3 the shortest. A threaded hole extending into its guide hole is provided on the side of the guide seat 8. When the telescopic pipe 3 is in the contracted state, the bolt 10 arranged in the threaded hole squeezes and locks the guide rod 9 to prevent the movable pipe 302 from moving freely.

[0041] Refer to Figure 1 and Figure 3 , a regulating valve 11 for adjusting the internal pressure is provided on the fixed pipe 301. The pressure is controlled according to the different angles of the telescopic pipe 3 to compensate for the influence of the self - weight of the grinding member 6 and the mounting bracket 5 on the elongation of the telescopic pipe 3. For example, for the fixed pipe 301 on the upper side, the direction of its gravity is opposite to the extending direction, that is, the pressure in the telescopic pipe 3 should be appropriately increased. For the fixed pipe on the lower side, the direction of its gravity is the same as the extending direction, so the regulating valve 11 is adjusted smaller.

[0042] Refer to Figure 2 , since the overall parts for grinding and cleaning are disk - shaped, before use, try to control the vehicle body 1 so that the center of the water distribution plate 2 is at the center of the circle of the tunnel cross - section. A distance sensor 17 facing the inner wall of the tunnel is installed outside the shaft tube 13. It is better to have two sensors facing different angles. The distance between the water distribution plate 2 and the tunnel wall is detected by the distance sensor 17, and then adjusted continuously to make the center of the water distribution plate 2 and the center of the tunnel as coincident as possible.

[0043] Refer to Figure 2, specifically, the water supply assembly includes a shaft seat 12, a shaft tube 13, a delivery hose 14, a water tank 15, and a water pump 16; the shaft seat 12 and the water tank 15 are fixed on the vehicle body 1, the shaft tube 13 is rotatably arranged in the shaft seat 12, one end of the shaft tube 13 is fixed on the end face of the water distribution plate 2, the other end is connected to the delivery hose 14, and the other end of the delivery hose 14 is connected to the interface at the bottom of the water tank 15, and the water pump 16 is arranged on the delivery hose 14. The water for cleaning the tunnel is stored in the water tank 15, and after being increased to a suitable pressure by the water pump 16, the water enters the water distribution plate 2 through the delivery hose 14 and the shaft tube 13.

[0044] The function of the driving assembly is to drive the water distribution plate 2 to rotate. For the convenience of pipeline and wiring, the water distribution plate 2 only needs to rotate at a small angle to ensure that the grinding part 6 can be completely covered. The driving assembly can be a rotary motor 18, a first gear 19, and a second gear 20. The rotary motor 18 is fixed on the vehicle body 1, the first gear 19 is fixed on the output shaft of the rotary motor 18, and the second gear 20 meshing with the first gear 19 is fixed on the shaft tube 13. The shaft tube 13 is driven to rotate in the shaft seat 12 by the two gears. The driving assembly can also be replaced by other reciprocating rotary devices.

[0045] The parts not detailed in this embodiment are prior art.

[0046] It should be noted that although the present invention has been described through the above embodiments, the present invention can also have many other embodiments. Without departing from the spirit and scope of the present invention, those skilled in the art can obviously make various corresponding changes and deformations to the present invention, but these changes and deformations should all fall within the scope protected by the appended claims of the present invention and their equivalents.
