Description

Technical Field

[0001] The utility model relates to the field of tunnel construction, in particular to a tunnel inner wall coating spraying device. Background Art

[0002] Coatings extend the life of tunnels by protecting them from harmful substances such as moisture, salt, and pollutants. For example, waterproof coatings effectively prevent water from penetrating the tunnel interior and damaging the concrete.

[0003] Tunnel coatings are applied to the interior of tunnels for a variety of reasons, including improving durability, fire resistance, lighting, and aesthetics. The selection and application of these coatings should be tailored to the specific conditions and needs of the tunnel to ensure optimal results.

[0004] The existing tunnel inner wall coating spraying generally adopts manual spraying on the tunnel inner wall. It is found in use and observation that this spraying method is not only labor-intensive, but also requires manual change of the spraying station when the spraying position needs to be adjusted during use, which will lead to uneven thickness of the tunnel inner wall coating spraying.

[0005] Therefore, in order to solve the above problems, a tunnel inner wall coating spraying device is proposed. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the utility model to solve its technical problems is: the tunnel inner wall coating spraying device described in the utility model comprises a driving base; a pair of track frames are fixedly connected to the driving base; a track is provided on the track frame; a driving slider is slidably connected to the track frame; a connecting plate is fixedly connected to the driving slider; a plurality of spray pipes are connected to the connecting plate; the driving base is fixedly connected to the paint box; the paint box is connected to a delivery pump; the delivery pump is connected to a delivery pipe; the delivery pipe is made of elastic material; the delivery pipe and the connecting plate are in a connecting relationship. The driving slider is slidably connected to the track, and the driving slider is opened when different positions need to be sprayed. When the driving slider is opened, the position of the spray pipe is driven to move, and the spray pipe sprays different positions on the inner wall of the tunnel. The sliding spray pipe can spray the inner wall of the tunnel more evenly, reducing the inconvenience of spraying at different positions and the situation that uneven coating spraying thickness is easily caused when adjusting the spraying position.

[0008] Preferably, a water tank is fixedly connected to the driving base; a water pump is connected to the water tank; a water pipe is connected to the water pump; the end of the water pipe is connected to a water supply plate; the water supply plate and the driving base are fixedly connected; a plurality of water spray pipes are connected to the water supply plate. By connecting the plurality of water spray pipes to the water supply plate, when water flows into the water supply plate and then is sprayed out from the water spray pipes, the sprayed water moistens the inner wall of the tunnel, which can reduce the situation where the coating on the inner wall of the tunnel is too dry during the spraying work.

[0009] Preferably, a support plate is fixedly connected to the driving base; an air pump is connected to the support plate; a connecting pipe is connected to the air pump; the end of the connecting pipe is connected to an air supply pipe; a plurality of air outlet pipes are connected to the air supply pipe; by opening a plurality of air outlet pipes on the air supply pipe, when air enters the air supply pipe, it is ejected from the air outlet pipe, and the ejected gas dries the paint on the inner wall of the tunnel, so that the paint sprayed on the inner wall of the tunnel can dry faster and adhere to the inner wall of the tunnel, making subsequent work in the tunnel more convenient.

[0010] Preferably, an elastic rope is fixed to the inner wall of the air pump; a cover plate is fixed to the end of the elastic rope; the cover plate and the air outlet pipe are in a hinged relationship. By fixing the elastic rope to the inner wall of the air outlet pipe and fixing the cover plate to the end of the elastic rope, when air does not pass through the air outlet pipe, the elastic rope pulls the cover plate back to seal the air outlet pipe, which can reduce the situation where dust and impurities enter the air outlet pipe when the air outlet pipe is not in use and cause the air outlet pipe to be blocked.

[0011] Preferably, a scraper is fixedly connected to the driving base; the scraper and the water supply plate are fixedly connected. By fixing the scraper to the water supply plate, the scraper contacts the inner wall of the tunnel when it moves to clean the inner wall of the tunnel, which can make the inner wall of the tunnel smoother and flatter, and improve the adhesion effect of the paint on the inner wall of the tunnel.

[0012] Preferably, a collecting box is fixedly connected to the driving base; the collecting box is located between the driving base and the scraper, and the inner wall of the tunnel is cleaned when the scraper contacts the inner wall of the tunnel. When the scraper cleans the impurities on the inner wall of the tunnel, the dust and impurities fall off, and the collecting box collects the fallen dust and impurities. By fixing the collecting box on the driving base, the dust and impurities cleaned by the scraper can be collected, which is more convenient for the subsequent unified treatment of the dust and impurities.

[0013] The utility model is beneficial in that:

[0014] 1. The tunnel inner wall coating spraying device described in the utility model is connected to a driving slider that slides on a track. The driving slider is turned on when it is necessary to spray different positions. When the driving slider is turned on, the position of the spray pipe is driven to move, and the spray pipe sprays different positions of the tunnel inner wall. The sliding spray pipe can spray the tunnel inner wall more evenly, reducing the inconvenience of spraying at different positions and the uneven coating spraying thickness that may occur when adjusting the spraying position.

[0015] 2. The tunnel inner wall coating spraying device described in the utility model has multiple water spray pipes connected to the water supply plate. When water flows into the water supply plate, it is sprayed out from the water spray pipes. The sprayed water moistens the inner wall of the tunnel, which can reduce the situation where the inner wall of the tunnel is too dry during the spraying of the tunnel inner wall coating, resulting in poor adhesion of the coating on the inner wall of the tunnel.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Specific examples are given below.

[0025] like Figures 1 to 5 As shown, a tunnel inner wall coating spraying device described in an embodiment of the present utility model includes a driving base 1; a pair of track frames 11 are fixedly connected to the driving base 1; a track 12 is provided on the track frame 11; a driving slider 13 is slidably connected to the track frame 11; a connecting plate 14 is fixedly connected to the driving slider 13; a plurality of spraying pipes 15 are connected to the connecting plate 14; a paint box 16 is fixedly connected to the paint box 16; a delivery pump 17 is connected to the delivery pump 17; the delivery pipe 18 is connected to the delivery pipe 18; the delivery pipe 18 is made of elastic material; the delivery pipe 18 and the connecting plate 14 are in a connecting relationship. When it is necessary to spray the inner wall of the tunnel, the driving base 1 is turned on, and the driving base 1 is turned on and the delivery pump 17 is turned on at the same time. When the delivery pump 17 is turned on, the paint is injected from the inside of the paint box 16 into the delivery pipe 18, and the paint enters the inside of the connecting plate 14 through the delivery pipe 18. The paint is sprayed on the inner wall of the tunnel by the multiple spraying pipes 15 connected to the connecting plate 14. When the paint enters the interior of the connecting plate 14, it will be sprayed out from the multiple spraying pipes 15 connected to the connecting plate 14. The paint sprayed from the spraying pipes 15 is sprayed on the inner wall of the tunnel. When the spraying position needs to be adjusted, the driving slider 13 is turned on. After the driving slider 13 is turned on, the driving slider 13 is driven to move along the track 12. The movement of the driving slider 13 drives the connecting plate 14 to move at the same time. When the connecting plate 14 moves, different positions of the inner wall of the tunnel are sprayed. The sliding spraying pipes 15 can spray the inner wall of the tunnel more evenly, reducing the inconvenience of spraying at different positions and the uneven coating spraying thickness caused by adjusting the spraying position.

[0026] like Figure 2As shown, the driving base 1 is fixedly connected to a water tank 2; the water tank 2 is connected to a water pump 21; the water pump 21 is connected to a water pipe 22; the end of the water pipe 22 is connected to a water delivery plate 23; the water delivery plate 23 and the driving base 1 are fixedly connected; the water delivery plate 23 is connected to a plurality of water spray pipes 24. When the inner wall of the tunnel needs to be sprayed, the water pump 21 is turned on. At this time, the water flow in the water tank 2 is injected into the water delivery pipe 22, and the water flows into the water delivery plate 23 through the water delivery pipe 22. When the water flows into the water delivery plate 23, The water is sprayed out from multiple water pipes 24 connected to the water supply plate 23 in atomized form, and the sprayed water comes into contact with the inner wall of the tunnel to moisten the inner wall of the tunnel. Subsequently, the paint sprayed from the spray pipe 15 is sprayed on the inner wall of the tunnel. Since multiple water pipes 24 are connected to the water supply plate 23, when the water flows into the interior of the water supply plate 23, it is sprayed out from the water pipes 24. The sprayed water moistens the inner wall of the tunnel, which can reduce the situation where the inner wall of the tunnel is too dry during the spraying of the coating on the inner wall of the tunnel, resulting in poor adhesion of the paint on the inner wall of the tunnel.

[0027] like Figure 3 As shown, the driving base 1 is fixed with a support plate 3; the support plate 3 is connected to an air pump 31; the air pump 31 is connected to a connecting pipe 32; the end of the connecting pipe 32 is connected to an air supply pipe 33; the air supply pipe 33 is connected to multiple air outlet pipes 34; when the spraying pipe 15 completes the spraying work on the inner wall of the tunnel, the air pump 31 is turned on. When the air pump 31 is turned on, air is pumped into the connecting pipe 32 and then into the air supply pipe 33. When the air enters the air supply pipe 33, it is discharged from the outlet pipe 34. The gas is sprayed out from multiple outlet pipes 34 connected to the air pipe 33, and the gas after being sprayed contacts the paint on the inner wall of the tunnel to air-dry the paint. By opening multiple outlet pipes 34 on the air supply pipe 33, when the air enters the air supply pipe 33, it is sprayed out from the outlet pipe 34, and the gas after being sprayed dries the paint on the inner wall of the tunnel, which can make the paint sprayed on the inner wall of the tunnel dry faster and adhere to the inner wall of the tunnel, making subsequent work in the tunnel more convenient.

[0028] like Figure 4As shown, an elastic rope 4 is fixedly connected to the inner wall of the air pump 31; a cover plate 41 is fixedly connected to the end of the elastic rope 4; the cover plate 41 and the air outlet pipe 34 are in a hinged relationship. When air is ejected from the air outlet pipe 34 through the air supply pipe 33, the elastic rope 4 is stretched. At this time, the cover plate 41 is lifted up by the air and the air is ejected smoothly through the air outlet pipe 34. When the air pump 31 is turned off, the air flow through the air outlet pipe 34 gradually decreases. At this time, the cover plate 41 is pulled back under the action of the elastic force of the elastic rope 4 itself, and the cover plate 41 closes the air outlet pipe 34. By fixing the elastic rope 4 to the inner wall of the air outlet pipe 34 and fixing the cover plate 41 to the end of the elastic rope 4, when air does not pass through the air outlet pipe 34, the elastic rope 4 pulls the cover plate 41 back to close the air outlet pipe 34, which can reduce the situation where dust and impurities enter the air outlet pipe 34 when the air outlet pipe 34 is not in use and cause the air outlet pipe 34 to be blocked.

[0029] like Figure 5 As shown, a scraper 5 is fixedly connected to the driving base 1; the scraper 5 and the water supply plate 23 are fixedly connected. When the driving base 1 moves forward, the scraper 5 is driven to move forward with it. When the scraper 5 moves forward, the edge of the scraper 5 contacts the inner wall of the tunnel. When the scraper 5 contacts the inner wall of the tunnel, impurities on the inner wall of the tunnel are cleaned. By fixing the scraper 5 on the water supply plate 23 and contacting the inner wall of the tunnel when the scraper 5 moves to clean the inner wall of the tunnel, the inner wall of the tunnel can be made smoother and flatter, thereby improving the adhesion effect of the paint on the inner wall of the tunnel.

[0030] like Figure 5 As shown, a collecting box 6 is fixedly connected to the driving base 1; the collecting box 6 is located between the driving base 1 and the scraper 5. When the scraper 5 contacts the inner wall of the tunnel, the inner wall of the tunnel is cleaned. When the scraper 5 cleans the impurities on the inner wall of the tunnel, the dust and impurities fall off. At this time, the collecting box 6 collects the fallen dust and impurities. By fixing the collecting box 6 on the driving base 1, the dust and impurities cleaned by the scraper 5 can be collected, which is more convenient for the subsequent unified treatment of the dust and impurities.

[0031] Working principle: When it is necessary to spray the inner wall of the tunnel, turn on the driving base 1, and turn on the driving base 1 and the delivery pump 17 at the same time. When the delivery pump 17 is turned on, the paint is injected from the inside of the paint box 16 into the delivery pipe 18, and the paint enters the inside of the connecting plate 14 through the delivery pipe 18. When the paint enters the inside of the connecting plate 14, it will be sprayed out from the multiple spray pipes 15 connected on the connecting plate 14. The paint sprayed from the spray pipes 15 sprays the inner wall of the tunnel. When it is necessary to adjust the spraying position, turn on the driving slider 13. When the driving slider 13 is turned on, the driving slider 13 moves along the The track 12 moves, driving the slider 13 to move and driving the connecting plate 14 to move at the same time. When the connecting plate 14 moves, it sprays different positions on the inner wall of the tunnel. When the inner wall of the tunnel needs to be sprayed, the water pump 21 is turned on. At this time, the water flow inside the water tank 2 is injected into the water pipe 22. The water flows into the water delivery plate 23 through the water delivery pipe 22. When the water flows into the water delivery plate 23, it is atomized and sprayed from the multiple water spray pipes 24 connected to the water delivery plate 23. The atomized water flows in contact with the inner wall of the tunnel and wets the inner wall of the tunnel. Then the paint sprayed from the spray pipe 15 sprays the inner wall of the tunnel. When the spraying operation is carried out, the air pump 31 is turned on when the spraying pipe 15 completes the spraying operation on the inner wall of the tunnel. When the air pump 31 is turned on, air is pumped into the connecting pipe 32 and then into the air supply pipe 33. After the air enters the air supply pipe 33, it is ejected from multiple air outlet pipes 34 connected to the air supply pipe 33. The ejected gas contacts the paint on the inner wall of the tunnel and air-dries the paint. When the air is ejected from the air outlet pipe 34 through the air supply pipe 33, the elastic rope 4 is stretched. At this time, the cover plate 41 is lifted up by the air and the air is ejected smoothly through the air outlet pipe 34. When the air pump 31 is turned off, the air is ejected from the outlet pipe 34. The airflow in the air pipe 34 gradually decreases. At this time, the cover plate 41 is pulled back under the elastic force of the elastic rope 4 itself. At this time, the cover plate 41 closes the air outlet pipe 34. When the driving base 1 moves forward, it drives the scraper 5 to move forward. When the scraper 5 moves forward, the edge of the scraper 5 contacts the inner wall of the tunnel. When the scraper 5 contacts the inner wall of the tunnel, the impurities on the inner wall of the tunnel are cleaned. When the scraper 5 contacts the inner wall of the tunnel, the inner wall of the tunnel is cleaned. After the scraper 5 cleans the impurities on the inner wall of the tunnel, the dust and impurities fall off. At this time, the collection box 6 collects the fallen dust and impurities.
