Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to an automatic walking tunnel inner wall spraying device. Background Technology

[0002] With the development of society, economy, and production, a large number of expressways have emerged, placing higher standards on road construction technology, requiring straight routes, gentle gradients, and wide road surfaces. Therefore, when roads traverse mountainous areas, the old method of winding mountain roads has often been replaced by tunnels. The construction of highway tunnels plays a vital role in improving the technical condition of highways, shortening travel distances, increasing transport capacity, and reducing accidents. After the completion of all basic engineering works for highway tunnels, the inner walls of the tunnels need to be coated with protective materials for surface protection.

[0003] In existing technologies, the method of spraying protective coatings on the inner walls of tunnels generally involves operators standing on a lift and holding a spray gun to spray the inner walls of the tunnel. This not only makes it difficult to ensure the uniformity of the coating, but also results in low efficiency due to the difficulty of spraying. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, the method of spraying protective coatings on the inner wall of tunnels generally involves operators standing on a lift and holding a spray gun to spray the inner wall of the tunnel. This not only makes it difficult to ensure the uniformity of the coating, but also results in low efficiency due to the difficulty of spraying.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an automatically moving tunnel inner wall spraying device, comprising: a vehicle body, and further comprising:

[0006] A support table is fixedly connected to the top of the vehicle body. A first fixing plate is fixedly connected to the top of the support table. A motor is fixedly connected to one side of the first fixing plate. A round rod is fixedly connected to the output end of the motor. A sliding rod is fixedly connected to the eccentric part of the round rod. A second fixing plate is fixedly connected to the top of the support table. A round rod is fixedly connected to one side of the second fixing plate. A movable strip is rotatably connected to one end of the round rod. A guide groove is opened on the side of the movable strip near the bottom. One end of the sliding rod is slidably connected to the inside of the guide groove. A sliding bar is provided inside the movable strip. A U-shaped plate is fixedly connected to one end of the sliding bar. A limit component is provided on one side of the movable strip. A spraying mechanism is provided above the vehicle body. The spraying mechanism includes a guide pipe. The guide pipe is fixedly connected to the U-shaped plate. Multiple spray nozzles are fixedly connected at equal intervals on the outer surface of the guide pipe.

[0007] Preferably, the spraying mechanism further includes a material barrel, which is fixedly connected to the vehicle body. A pump body is fixedly connected to the top of the vehicle body, and a liquid extraction pipe is fixedly connected to the liquid extraction end of the pump body. One end of the liquid extraction pipe is fixedly connected to the outer surface of the material barrel near the bottom.

[0008] Preferably, a telescopic hose is fixedly connected to the outlet end of the pump body, and one end of the telescopic hose is fixedly connected to one end of the guide pipe.

[0009] Preferably, the telescopic hose, the guide pipe, and the multiple nozzles are connected together, and the liquid extraction pipe is connected to the material tank.

[0010] Preferably, the limiting component includes a limiting rod, which is slidably connected to the movable strip. The movable strip has multiple limiting holes equidistantly opened on one side, and one end of the limiting rod is slidably connected inside one of the limiting holes.

[0011] Preferably, a spring is provided on the outer surface of the limiting rod, and the spring is fixedly connected to the limiting rod and the movable bar respectively.

[0012] Preferably, a stirring rod is rotatably connected inside the material barrel, the stirring rod is rotatably connected to the support table, and a bevel gear is fixedly connected to one end of the stirring rod, the bevel gear one meshing with a bevel gear two.

[0013] Preferably, the top of the support table has two circular holes, and the outer surface of the telescopic hose is movably connected to the inside of the first circular hole. The top of the material barrel is fixedly connected to a feeding hopper, which is connected to the material barrel. The outer surface of the feeding hopper is movably connected to the inside of the second circular hole.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model uses a controller to start a motor, causing its output shaft to drive the bevel gear and slide rod to rotate. This causes the slide rod to slide inside the guide groove and apply a force to the movable bar, causing it to swing back and forth around the outer surface of the round rod. Simultaneously, this causes the slide rod, U-shaped plate, guide pipe, and nozzle to swing back and forth. At the same time, the controller starts the pump, which draws the paint from the tank through the extraction pipe. The paint then passes through the telescopic hose, guide pipe, and nozzle, and is sprayed onto the inner wall of the tunnel. This eliminates the need for manual operation, ensuring uniform paint application and improving the efficiency of tunnel inner wall spraying.

[0016] 2. In this utility model, the rotation of bevel gear two, and the meshing action of bevel gear two and bevel gear one, can drive bevel gear one to rotate, so that the stirring rod can continuously stir the coating inside the material tank. This can prevent the coating from settling due to long-term standing and ensure the uniformity of the coating.

[0017] 3. In this utility model, by manually pulling the limiting rod to one side, it disengages from the limiting hole, releasing the limiting of the slide bar. Simultaneously, the spring is stretched, allowing the slide bar to slide up or down along the inside of the movable strip, adjusting the height of the U-shaped plate, guide tube, and nozzle. Then, the limiting rod is released, allowing it to be inserted into the limiting hole under the restoring force of the spring, limiting the slide bar. This allows for appropriate adjustment according to the height of the tunnel top inner wall, adjusting the nozzle to a suitable position, thus avoiding the situation where the nozzle is too far from the tunnel top inner wall, resulting in incomplete spraying.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Examples, such as Figure 1-4 As shown, this utility model provides an automatic walking tunnel inner wall spraying device, including: a vehicle body 1, and a support table 11 fixedly connected to the top of the vehicle body 1. A fixing plate 3 is fixedly connected to the top of the support table 11. A motor 37 is fixedly connected to one side of the fixing plate 3. A round rod 36 is fixedly connected to the output end of the motor 37. A sliding rod 39 is fixedly connected to the eccentric part of the round rod 36. A second fixing plate 31 is fixedly connected to the top of the support table 11. A round rod 36 is fixedly connected to one side of the second fixing plate 31. One end of 6 is rotatably connected to a movable strip 32. A guide groove 35 is provided on the side of the movable strip 32 near the bottom. One end of the slide rod 39 is slidably connected inside the guide groove 35. A slide bar 33 is provided inside the movable strip 32. A U-shaped plate 34 is fixedly connected to one end of the slide bar 33. A limit component is provided on one side of the movable strip 32. A spraying mechanism is provided above the vehicle body 1. The spraying mechanism includes a guide pipe 23. The guide pipe 23 is fixedly connected to the U-shaped plate 34. Multiple nozzles 24 are fixedly connected at equal intervals on the outer surface of the guide pipe 23.

[0027] Furthermore, such as Figure 1-4 As shown, the spraying mechanism also includes a material tank 2, which is fixedly connected to the vehicle body 1. A pump body 21 is fixedly connected to the top of the vehicle body 1. A liquid extraction pipe 28 is fixedly connected to the liquid extraction end of the pump body 21. One end of the liquid extraction pipe 28 is fixedly connected to the outer surface of the material tank 2 near the bottom. The pump body 21 is started by the controller so that it can extract the paint inside the material tank 2 through the liquid extraction pipe 28.

[0028] Furthermore, such as Figure 1-4 As shown, a telescopic hose 22 is fixedly connected to the outlet end of the pump body 21. One end of the telescopic hose 22 is fixedly connected to one end of the guide pipe 23. With the setting of the telescopic hose 22, when the guide pipe 23 moves up and down or swings left and right, the telescopic hose 22 can be appropriately stretched or contracted.

[0029] Furthermore, such as Figure 1-4As shown, the telescopic hose 22, the guide pipe 23 and the multiple nozzles 24 are connected, and the liquid extraction pipe 28 is connected to the material tank 2. With the above arrangement, the coating can pass through the telescopic hose 22, the guide pipe 23 and the nozzles 24 in sequence, and be sprayed onto the inner wall of the tunnel through the nozzles 24.

[0030] Furthermore, such as Figure 1-4 As shown, the limiting component includes a limiting rod 4, which is slidably connected to the movable strip 32. Multiple limiting holes 310 are equidistantly provided on one side of the slide strip 33. One end of the limiting rod 4 is slidably connected to the inside of one of the limiting holes 310. By pulling the limiting rod 4 to one side by hand, it is disengaged from the inside of the limiting hole 310, thereby releasing the limiting of the slide strip 33.

[0031] Furthermore, such as Figure 1-4 As shown, a spring 41 is provided on the outer surface of the limiting rod 4. The spring 41 is fixedly connected to the limiting rod 4 and the movable bar 32 respectively. Under the reset force of the spring 41, the limiting rod 4 can be inserted into the limiting hole 310 to limit the slide bar 33.

[0032] Furthermore, such as Figure 1-4 As shown, a stirring rod 26 is rotatably connected inside the material bucket 2. The stirring rod 26 is rotatably connected to the support table 11. One end of the stirring rod 26 is fixedly connected to a bevel gear 27. The bevel gear 27 meshes with a bevel gear 38. Through the rotation of the bevel gear 38 and the meshing action of the bevel gear 38 and the bevel gear 27, the bevel gear 27 can drive the stirring rod 26 to rotate, so that the stirring rod 26 continuously stirs the coating inside the material bucket 2.

[0033] Furthermore, such as Figure 1-4 As shown, the top of the support table 11 has a first circular hole 12 and a second circular hole 13. The outer surface of the telescopic hose 22 is movably connected to the inside of the first circular hole 12. The top of the material bucket 2 is fixedly connected to the feed hopper 25, which is connected to the material bucket 2. The outer surface of the feed hopper 25 is movably connected to the inside of the second circular hole 13. The first circular hole 12 and the second circular hole 13 facilitate the passage of the telescopic hose 22 and the feed hopper 25, respectively. The feed hopper 25 facilitates the addition of paint to the material bucket 2.

[0034] Working Principle: During operation, paint is added to the material tank 2 through the feed hopper 25. The controller then starts the motor 37, causing its output shaft to drive the bevel gear 38 and slide bar 39 to rotate. This causes the slide bar 39 to slide within the guide groove 35, applying a force to the movable bar 32, causing it to oscillate left and right around the outer surface of the round rod 36. Simultaneously, this oscillates the slide bar 33, U-shaped plate 34, guide pipe 23, and nozzle 24. Simultaneously, the controller starts the pump 21, which draws the paint from the material tank 2 through the extraction pipe 28. The paint then passes through the telescopic hose 22, guide pipe 23, and nozzle 24, spraying it onto the tunnel wall. This eliminates the need for manual operation, ensuring uniform paint application and improving tunnel wall spraying efficiency. Furthermore, the vehicle 1 moves automatically within the tunnel, changing spraying areas, all synchronized with the rotation of the bevel gear 38. Under the meshing action of bevel gear 28 and bevel gear 27, bevel gear 27 can drive the stirring rod 26 to rotate, so that the stirring rod 26 continuously stirs the paint inside the material bucket 2. This can prevent the paint from settling due to long-term standing and ensure the uniformity of the paint. By pulling the limiting rod 4 to one side by hand, it is disengaged from the inside of the limiting hole 310, releasing the limiting of the slide bar 33. At the same time, the spring 41 is stretched. At this time, the slide bar 33 can slide up or down along the inside of the movable bar 32 to adjust the height of the U-shaped plate 34, the guide pipe 23 and the nozzle 24. Then, the limiting rod 4 is released, and under the reset force of the spring 41, it is inserted into the inside of the limiting hole 310 to limit the slide bar 33. In this way, the height of the inner wall of the tunnel top can be adjusted appropriately to adjust the nozzle 24 to a suitable position, thereby avoiding the situation where the nozzle 24 is too far from the inner wall of the tunnel top and the spraying is not in place.

[0035] 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 other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
