Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a dome cleaning device for tunnel construction. Background Technology

[0002] Tunnels are engineering structures buried underground, representing a form of human utilization of underground space. Tunnels can be categorized into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels.

[0003] After tunnel construction, a dome cleaning device is needed to clean the dome. During cleaning, water is usually sprayed onto the dome in conjunction with brush rollers. However, when water is sprayed onto the dome surface, a large amount of water mist is generated. Since the cleaning is done by workers standing on a cleaning vehicle to operate the cleaning device, the large amount of water mist will wet the workers' clothes, which can easily cause them to catch a cold or get sick. Therefore, we have proposed a dome cleaning device for tunnel construction. Utility Model Content

[0004] The purpose of this invention is to provide a dome cleaning device for tunnel construction to solve the problems mentioned in the background art.

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] Please see Figure 1-5 As shown, a dome cleaning device for tunnel construction includes a turntable 1 and a base 2 mounted on top of the turntable 1. A robotic arm 3 is mounted on top of the base 2. The robotic arm 3 is existing technology and will not be described further in this solution. A water tank 4 is mounted on top of the base 2. A first connecting pipe 8 is connected to the front of the water tank 4. A water pump 5 is connected to the other end of the first connecting pipe 8. A second connecting pipe 9 is connected to the output end of the water pump 5. The water pump 5 is fixedly connected to the top of the base 2. A tee pipe 11 is connected to the other end of the second connecting pipe 9. Both the upper and lower ends of the tee pipe 11 are connected to first branch pipes 12. A shield 6 is fixedly connected to the front of the robotic arm 3. The other end of the first branch pipe 12 is fixed... The first branch pipe 12 extends through the shield 6 and into its interior. Several nozzles 17 are provided at the other end of the first branch pipe 12. The top of the water tank 4 is connected to the third connecting pipe 13. The second connecting pipe 9 and the third connecting pipe 13 are both flexible hoses that can adapt to the movement of the robotic arm 3 and prevent the second connecting pipe 9 and the third connecting pipe 13 from breaking when the robotic arm 3 moves. The other end of the third connecting pipe 13 is connected to the second branch pipe 14. The other end of the second branch pipe 14 is connected to the interior of the shield 6. Several filter structures 16 are provided on the front side of the second branch pipe 14. A brush roller 15 is rotatably connected inside the shield 6. Shielding structures 7 are provided on both the upper and lower sides of the shield 6.

[0016] The shielding structure 7 includes shielding plates 71 hinged to the upper and lower sides of the shielding cover 6. Electric push rods 72 are hinged to both sides of the shielding plate 71 and the shielding cover 6. The opening and closing angle can be adjusted by starting and stopping the electric push rods 72 to further expand or shrink the shielding range, adapt to different working scenarios, and thus shield the overflowing water mist.

[0017] The filter structure 16 includes a filter sleeve 161 threadedly connected to the front side of the second branch pipe 14. A filter screen 162 is provided inside the filter sleeve 161 so that water droplets attached to the inside of the shield 6 can be gathered together and flow through the second branch pipe 14 to the water tank 4. The water is filtered by the filter screen 162 to prevent impurities from clogging the second branch pipe 14. At the same time, when the filter screen 162 is clogged, the filter sleeve 161 can be easily removed to clean the filter screen 162.

[0018] Several locking blocks 10 are provided on the top and left side of the robotic arm 3. The inner diameter of the locking blocks 10 is the same as the diameter of the second connecting pipe 9 and the third connecting pipe 13. They can be used to lock the second connecting pipe 9 and the third connecting pipe 13, and play a fixing role to prevent the second connecting pipe 9 and the third connecting pipe 13 from shaking, getting tangled or falling off when the robotic arm 3 moves, thus ensuring stable water transmission.

[0019] The top of the water tank 4 is provided with a water inlet 18, and the rear side of the water tank 4 is connected to a drain pipe 19. The surface of the drain pipe 19 is provided with a drain valve to facilitate the replenishment of cleaning water into the water tank 4, ensuring a continuous water supply. At the same time, after cleaning, the water in the water tank 4 can be drained through the drain pipe 19 to prevent the water in the water tank 4 from deteriorating and becoming contaminated due to long-term storage.

[0020] A motor is installed on one side of the shield 6. One end of the brush roller 15 rotates through the shield 6 and is fixedly connected to the output shaft of the motor. Driven by the motor, the brush roller 15 can be rotated.

[0021] Working principle: When workers clean the tunnel dome, they first add enough clean water to the water tank 4 through the water inlet 18. Then, the robotic arm 3 is activated to extend upwards, and the brush roller 15 is then placed against the dome. Next, the electric push rod 72 is activated, which drives the baffle plate 71 to deflect according to the angle of the dome. At this time, the brush roller 15 and the water pump 5 can be activated simultaneously, causing the brush roller 15 to rotate. The water pump 5 then transports the clean water in the water tank 4 to the inside of the water pump 5 through the first connecting pipe 8, and then through the first branch pipes 12 on both sides of the second connecting pipe 9. The water is transported and then sprayed onto the dome through nozzle 17. This works in conjunction with brush roller 15 to clean the dome. The sprayed water collides with the dome, generating a large amount of water mist. Some water droplets are blocked by shield 6 and condense inside the shield 6, while the scattered water mist is blocked by shield plate 71 to prevent it from wetting the workers' clothes. The water condensed inside the shield 6 can be filtered through filter screen 162 to remove impurities and then flows to the second branch pipe 14 and the third connecting pipe 13, and then into water tank 4, realizing the reuse of water source and saving water resources.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
