Description

Technical Field

[0001] This utility model relates to the field of spray head equipment technology, specifically a rapid spraying and forming device for a special ceramic coating for tunnels. Background Technology

[0002] Tunnels are structures built underground, underwater, or in mountains to carry railways or highways for motor vehicles. Based on their location, they can be divided into three main categories: mountain tunnels, underwater tunnels, and urban tunnels. During tunnel construction, markings or lines are sprayed or drawn on the tunnel walls or ground to facilitate construction. Currently, most construction sites use manual spraying, which is inefficient and results in uneven mixing of the paint, directly affecting construction efficiency.

[0003] Publication number CN215655844U discloses a spraying device for open-cut tunnel construction. The device connects a nozzle to a second connecting pipe via a rubber hose, offering better application results compared to fixed pipes. Workers can also hold the nozzle by hand for spraying, providing more options and adaptability to tunnel environments with fewer limitations and greater versatility. However, this patent still has the following problems in practical use:

[0004] The nozzle is connected to the second connecting pipe via a rubber tube, which provides better application results compared to a fixed pipe. Workers can also hold the nozzle by hand for spraying, offering more options and adaptability to tunnels in different environments. It has fewer limitations and better adaptability. However, the nozzle is limited by a retaining ring, which may cause the nozzle to detach from the retaining ring if the impact force generated during spraying is large.

[0005] A rapid spraying and forming device for a special ceramic coating for tunnels is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a rapid spraying and forming device for ceramic coatings specifically for tunnels, in order to solve the problem mentioned in the background art. Currently, the nozzle is connected to the second connecting pipe through a rubber tube. Compared with fixed pipes, this method has a better performance and allows workers to hold the nozzle by hand for spraying. It offers more choices, can adapt to tunnels in different environments, has fewer limitations, and is more adaptable. However, the nozzle is limited by a retaining ring, which may cause the nozzle to detach from the retaining ring when the impact force generated during spraying is large.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rapid spraying and forming device for a special ceramic coating for tunnels, comprising a base and pulleys, wherein the bottom surface of the base is fixedly connected to the pulleys around its perimeter;

[0008] A handle is fixedly connected to one side of the base near the top, and a support frame is fixedly connected to the other side of the base near the top. A box is connected through the middle of the support frame. Support rods are symmetrically installed on the bottom surface of the box. The bottom surface of the support rods is fixedly connected to the base. A support plate is fixedly installed on one side of the box. Connecting plates are symmetrically installed on the top surface of the support plate.

[0009] Also includes:

[0010] The surface of the connecting plate is provided with a limit assembly;

[0011] The limiting component includes a fixing frame that is fixedly connected to the connecting plate;

[0012] A tie rod is connected through the surface of the fixing frame near the middle.

[0013] Preferably, a limiting frame is connected through one side surface of the pull rod, the side surface of the limiting frame away from the pull rod is fixedly connected to the connecting plate, a spring is fixedly connected in the middle of one side surface of the limiting frame, a stabilizing frame is fixedly connected to the side surface of the spring away from the limiting frame, the spring is sleeved and connected to the pull rod, and the pull rod is connected through the stabilizing frame.

[0014] Preferably, a top rod is fixedly connected to the middle of the surface of the stabilizing frame away from the tie rod, and a locking block is fixedly connected to the surface of the top rod away from the stabilizing frame.

[0015] Preferably, a feed inlet is provided on one side of the top surface of the box, a motor box is fixedly installed in the middle of the top surface of the box, a drive motor is fixedly installed inside the motor box, and a discharge pipe is connected through the middle of the bottom surface of the box.

[0016] Preferably, a water pump is fixedly connected to the surface of the discharge pipe away from the box body, a hose is fixedly connected to the surface of the water pump away from the discharge pipe, and a nozzle is connected through the surface of the hose away from the water pump.

[0017] Preferably, the connecting plate has a through groove inside, which is connected to the stabilizing frame. A placement block is fixedly installed on the top surface of the support plate. The placement block is in close contact with the nozzle. The nozzle has symmetrical slots on both sides, which are engaged with the slots.

[0018] Preferably, a rotating rod is fixedly connected to the output end of the drive motor through one side surface of the housing. Several stirring blades are symmetrically installed on both sides of the surface of the rotating rod. A scraper is fixedly connected to the side surface of the stirring blade away from the rotating rod. The side surface of the scraper away from the stirring blade is in close contact with the housing.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This tunnel-specific ceramic coating rapid spraying and forming device, by setting a limiting component, can limit the nozzle, thereby preventing the nozzle from falling off even when a large impact force is generated during spraying. At the same time, it also makes the placement and removal of the nozzle more convenient. The specific details are as follows:

[0020] 1. By setting a limiting component, when the spray head needs to be picked up for spraying, pulling the lever moves the stabilizer, which in turn moves the top rod. The top rod then moves the locking block, causing it to separate from the slot. Simultaneously, the movement of the stabilizer compresses a spring, causing it to deform. After the locking block separates from the slot, the spray head can be removed, allowing the operator to hold the spray head for spraying. The spray head can then be placed back into position. When the nozzle is placed on the placement block, the pull rod is loosened, allowing the retaining bracket to return to its original position under the action of the spring. The movement of the retaining bracket causes the top rod to move, which in turn causes the locking block to move, allowing the locking block and the slot to re-engage. This engagement of the locking block and the slot prevents the nozzle from falling off when a large impact force is applied during spraying on the placement block, thus avoiding damage to the nozzle and extending its service life.

[0021] 2. By setting up a tank, motor housing, drive motor, rotating rod, stirring blade, and scraper, the drive motor is started through the control terminal, so that the output of the drive motor can drive the rotating rod to rotate. The rotation of the rotating rod can drive the rotation of the stirring blade, thereby stirring the liquid inside the tank evenly. At the same time, the rotation of the stirring blade can drive the rotation of the scraper, thereby cleaning the inner wall of the tank and preventing the liquid from adhering to the inner wall of the tank.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a rapid spraying and forming device for a tunnel-specific ceramic coating, comprising a base 1 and pulleys 2. The bottom surface of the base 1 is fixedly connected to the pulleys 2 around its perimeter. A handle 3 is fixedly connected to one side of the base 1 near the top, and a support frame 4 is fixedly connected to the other side of the base 1 near the top. A housing 5 is penetrated through the center of the support frame 4. Support rods 6 are symmetrically installed on the bottom surface of the housing 5, and the bottom surfaces of the support rods 6 are fixedly connected to the base 1. A support plate 14 is fixedly installed on one side of the housing 5, and connecting plates 15 are symmetrically installed on the top surface of the support plate 14. The device also includes a limiting component 16 on the surface of the connecting plate 15. The limiting component 16 includes a fixing frame 1601 fixedly connected to the connecting plate 15. A pull rod 1602 is penetrated through the middle side of the fixing frame 1601. Figure 1-5 As shown, by setting the limiting component 16, the nozzle 13 can be limited, so that the nozzle 13 will not fall off when a large impact force is generated during spraying. At the same time, it is more convenient to place and pick up the nozzle 13.

[0030] A limit bracket 1603 is connected through one side surface of the pull rod 1602. The side surface of the limit bracket 1603 away from the pull rod 1602 is fixedly connected to the connecting plate 15. A spring 1604 is fixedly connected to the middle of one side surface of the limit bracket 1603. A stabilizing bracket 1605 is fixedly connected to the side surface of the spring 1604 away from the limit bracket 1603. The spring 1604 is sleeved with the pull rod 1602. The pull rod 1602 and the stabilizing bracket 1605 are connected through the pull rod 1602. A top rod 1606 is fixedly connected to the middle of the side surface of the stabilizing bracket 1605 away from the pull rod 1602. A locking block 1607 is fixedly connected to the side surface of the top rod 1606 away from the stabilizing bracket 1605. Figure 3-5 As shown, by pulling the lever 1602, the lever 1602 can move the stabilizer 1605. Simultaneously, the movement of the stabilizer 1605 causes the top rod 1606 to move. The movement of the top rod 1606 causes the locking block 1607 to move, thus separating the locking block 1607 from the slot 19. Simultaneously, the movement of the stabilizer 1605 compresses the spring 1604, causing it to deform. After the locking block 1607 separates from the slot 19, the spray head 13 can be removed, allowing the operator to hold the spray head 13 for spraying. When placing the spray head 13, after placing it on the placement block 18, by loosening the lever 1602, the stabilizer 1605... Under the action of 1604, the device returns to its original position. The movement of the stabilizing bracket 1605 drives the movement of the top rod 1606, which in turn drives the movement of the locking block 1607. This allows the locking block 1607 to re-engage with the slot 19. The engagement of the locking block 1607 with the slot 19 prevents the nozzle 13 from falling off when it is placed on the placement block 18 and subjected to a large impact force during spraying. This avoids damage to the nozzle 13 and extends its service life. Furthermore, the spring 1604 is a compression spring in the prior art. Compression springs have a large elastic force, ensuring that the locking block 1607 and the slot 19 will not detach without human interference.

[0031] A feed inlet 7 is provided on one side of the top surface of the housing 5. A motor housing 8 is fixedly installed in the middle of the top surface of the housing 5, and a drive motor 9 is fixedly installed inside the motor housing 8. A discharge pipe 10 is connected through the middle of the bottom surface of the housing 5. A water pump 11 is fixedly connected to the side of the discharge pipe 10 away from the housing 5. A hose 12 is fixedly connected to the side of the water pump 11 away from the discharge pipe 10. A nozzle 13 is connected through the side of the hose 12 away from the water pump 11. Figure 2 As shown, this allows the stirred liquid to be delivered into the interior of the nozzle 13, thereby enabling the spraying process.

[0032] The connecting plate 15 has a through groove 17 inside, which is connected to the stabilizing frame 1605. A placement block 18 is fixedly installed on the top surface of the support plate 14, and the placement block 18 is fitted to the nozzle 13. The nozzle 13 has symmetrically arranged slots 19 on both sides, which engage with the locking block 1607. Figure 3 , 4 As shown, the engagement of the locking block 1607 with the locking slot 19 makes it more convenient to pick up and place the nozzle 13.

[0033] A rotating rod 20 is fixedly connected to one side surface of the housing 5 through the output end of the drive motor 9. Several stirring blades 21 are symmetrically installed on both sides of the rotating rod 20. A scraper 22 is fixedly connected to the side surface of the stirring blades 21 away from the rotating rod 20. The side surface of the scraper 22 away from the stirring blades 21 is in close contact with the housing 5. Figure 2 As shown, the drive motor 9 is started by the control terminal, so that the output terminal of the drive motor 9 can drive the rotation rod 20 to rotate. The rotation of the rotation rod 20 can drive the rotation of the stirring blade 21, thereby stirring the liquid inside the tank 5 evenly. At the same time, the rotation of the stirring blade 21 can drive the rotation of the scraper 22, so that the scraper 22 can clean the inner wall of the tank 5, thereby preventing the liquid from adhering to the inner wall of the tank 5.

[0034] Working principle: Before using this tunnel-specific ceramic coating rapid spraying and forming device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, when it is necessary to pick up and spray the nozzle 13, pulling the lever 1602 causes the stabilizer 1605 to move. The movement of the stabilizer 1605 then moves the top rod 1606, which in turn moves the locking block 1607, causing it to separate from the slot 19. Simultaneously, the movement of the stabilizer 1605 compresses the spring 1604, causing it to deform. After the locking block 1607 separates from the slot 19, the nozzle 13 can be removed, allowing the operator to hold it for spraying. The nozzle 13 can then be placed back into place. When the nozzle 13 is placed on the placement block 18, the pull rod 1602 is loosened, causing the retaining bracket 1605 to return to its original position under the action of the spring 1604. The movement of the retaining bracket 1605 can drive the movement of the top rod 1606, which in turn drives the movement of the locking block 1607. This allows the locking block 1607 to re-engage with the slot 19. The engagement of the locking block 1607 with the slot 19 prevents the nozzle 13 from falling off when it is placed on the placement block 18 and subjected to a large impact force during spraying, thus avoiding damage to the nozzle 13 and extending its service life.

[0035] Secondly, the drive motor 9 is started by the control terminal, so that the output of the drive motor 9 can drive the rotation rod 20 to rotate. The rotation of the rotation rod 20 can drive the rotation of the stirring blade 21, thereby stirring the liquid inside the tank 5 evenly. At the same time, the rotation of the stirring blade 21 can drive the rotation of the scraper 22, thereby cleaning the inner wall of the tank 5 and preventing the liquid from adhering to the inner wall of the tank 5.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
