DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, the anti-corrosion paint spraying device for concrete anti-corrosion construction provided by the utility model includes a frame 1, a reversing platform 2, a paint bucket 3, a feed pump 4 and a spray pipe 5.

[0034] Travel wheels are installed at the bottom of the frame 1, so that the entire paint spraying device can move along the concrete floor and spray in sequence along an "S"-shaped trajectory.

[0035] The reversing plate 2 is rotatably mounted on the upper surface of the frame 1, and the paint bucket 3 and the feed pump 4 are both mounted on the upper surface of the reversing plate 2. Specifically, the paint bucket 3 and the feed pump 4 are both mounted at the center of the reversing plate 2 to improve the balance performance of the entire device. A stirring motor is provided at the top of the paint bucket 3, and a stirring blade is provided in the stirring bucket. The stirring motor drives the stirring blade to rotate to stir the paint in the stirring bucket to improve the fluidity and uniformity of the paint.

[0036] A spray pipe 5 is provided on both sides of the reversing plate 2, so that there is a spray pipe 5 on each side of the reversing plate 2. During the spraying process, as the spraying device moves on the concrete floor, the two spray pipes 5 spray the left and right sides at the same time. The inner end of the spray pipe 5 is connected to the feed pump 4, and the spray pipe 5 is installed on the reversing plate 2 so that it can be displaced in the width direction. Among them:

[0037] When the spray pipe 5 moves outward to the position farthest from the reversing platen 2, the distance between its spraying area and the reversing platen 2 is the spraying width of the spray pipe 5. Specifically, when the spray pipe 5 is located at the innermost position, it directly sprays the anti-corrosion paint on the concrete areas on both sides of the frame 1; when the spray pipe 5 is located at the outermost position, it can spray across the concrete areas on both sides adjacent to the frame 1.

[0038] In order to facilitate those skilled in the art to effectively implement the present application, the spraying of the anti-corrosion coating is further described as follows:

[0039] First, based on the spraying area of ​​the spray pipe 5, the concrete floor is divided into the first column, the second column, ... the nth column from left to right.

[0040] Secondly, during the first spraying, the vehicle frame 1 is moved in the second column, and the spray pipes 5 on the left and right sides are sprayed corresponding to the first column and the third column respectively.

[0041] Third, when the second spraying is performed after the first spraying is completed, the frame 1 is moved to the 4th column, and one of the spray pipes 5 is moved to the outermost position, so that the spray pipe 5 at the outermost position sprays the 2nd column, and the other spray pipe 5 sprays the 5th column.

[0042] Fourthly, when the third spraying is performed after the second column is sprayed, the frame 1 is in the sixth column, the spray pipe 5 located at the outermost position sprays the fourth column, and the other spray pipe 5 sprays the seventh column. And so on, the anti-corrosion coating spraying operation of all concrete floors is completed in sequence.

[0043] The spray pipe 5 includes a first pipe body 5-1 and a second pipe body 5-2. The first pipe body 5-1 is a hard pipe body, which is slidably mounted on the reversing plate 2. The second pipe body 5-2 is a hose, and its two ends are respectively connected to the first pipe body 5-1 and the feed pump 4. The first pipe body 5-1 is provided with a spray head. The second pipe body 5-2 is a hose, so that when the spray pipe 5 moves inward and outward on the frame 1, the hose is continuously released and retracted, which can meet the needs of adjusting the position of the spray pipe 5.

[0044] The inner end of the first tube body 5-1 is sleeved with a tube sleeve 6, and the bottom of the tube sleeve 6 is rotatably sleeved with a guide plate 7, and the lower surface of the reversing table 2 is provided with a guide groove 8 for sliding the guide plate 7. When the spray pipe 5 moves inward and outward, the guide plate 7 moves in the guide groove 8, so that the guide plate 7 has a guiding effect on the displacement of the spray pipe 5.

[0045] The second tube body 5 - 2 is connected to the side of the first tube body 5 - 1 and is located outside the tube sleeve 6 . This arrangement ensures that the hose will not interfere with the displacement of the spray pipe 5 during the inward and outward displacement of the spray pipe 5 .

[0046] A telescopic rod 9 is arranged between the reversing table 2 and the pipe sleeve 6, and the extended end of the telescopic rod 9 is rotatably connected to the bottom of the pipe sleeve 6, and the fixed ends of the two telescopic rods 9 are rotatably mounted on the upper surface of the reversing table 2 through the left support shaft 10 and the right support shaft 11. Through such an arrangement, during the displacement of the spray pipe 5 in and out, the guide plate 7 cooperates with the telescopic rod 9 to keep the spray pipe 5 moving back and forth along a straight track, and at the same time, during the displacement of the spray pipe 5, the telescopic rod 9 swings and retracts.

[0047] Furthermore, the bottom ends of the left support shaft 10 and the right support shaft 11 are respectively mounted with a left gear 12 and a right gear 13, and the upper surface of the frame 1 is respectively fixed with a left arc-shaped rack 14 and a right arc-shaped rack 15 that can mesh with the left gear 12 and the right gear 13. Specifically, the teeth of the left arc-shaped rack 14 and the right arc-shaped rack 15 are on the arc track of the left gear 12 and the right gear 13 making a circular motion with the frame 1 as the center. Furthermore, when the reversing plate 2 rotates on the frame 1, the displacement of the spray pipe 5 is synchronously adjusted according to the rotation direction.

[0048] Among them, the right gear 13 is fixedly installed at the bottom end of the right support shaft 11, the left gear 12 is raised and lowered on the left support shaft 10 through the core shaft 16, and the core shaft 16 is provided with a gear lifting structure for lifting the left gear 12, and when the left gear 12 is in the lowest position, it is able to engage with the left arc-shaped rack 14, and when the left gear 12 is in the highest position, it is located above the left arc-shaped rack 14 in the height direction.

[0049] Specifically, after the first spraying is completed, when it is necessary to rotate the reversing plate 2, the left gear 12 is first lifted from the lowest position to the highest position through the gear lifting structure, and then the handle is operated to rotate the reversing plate 2 180°. During the rotation of the reversing plate 2, the right gear 13 rolls over the right arc-shaped rack 15, and in this process, the spray pipe 5 on the right side is displaced outward to the farthest position. At the same time, the left gear 12 at the highest position will pass over the left arc-shaped rack 14. After the reversing plate 2 rotates 180°, the right gear 13 rolls onto the left arc-shaped rack 14 and meshes with it, and the gear lifting structure lowers the left gear 12 to the lowest position. At this time, the left gear 12 meshes with the right arc-shaped rack 15, thereby having a positioning effect on the two spray pipes 5.

[0050] Furthermore, the gear lifting structure includes a connecting plate 17, a first connecting rod 18 and a second connecting rod 19. The bottom end of the handle is rotatably installed on the upper surface of the reversing table 2 in the front-to-back direction. The top end of the core shaft 16 passes through the left support shaft 10 and is connected to one end of the connecting plate 17. The bottom end of the first connecting rod 18 is rotatably connected to the other end of the connecting plate 17 in the front-to-back direction. The top end of the first connecting rod 18 is rotatably connected to one end of the second connecting rod 19. The other end of the second connecting rod 19 is fixedly connected to the front side of the handle.

[0051] Through the above arrangement, the handle is pressed backward to rotate backward, and the second connecting rod 19 is driven to move during the rotation of the handle. The front end of the second connecting rod 19 pulls the first connecting rod 18 upward, and the first connecting rod 18 lifts the core shaft 16 through the connecting plate 17, so that the left gear 12 moves from the lowest position to the highest position.

[0052] Furthermore, a gear groove 20 is provided on the lower surface of the reversing plate 2 just above the left gear 12. When the left gear 12 is at the highest position, it is located in the gear groove 20, and the left gear 12 is meshed with the inner wall of the gear groove 20. In this way, during the rotation of the reversing plate 2, the left gear 12 will not rotate, thereby keeping the position of the left spray pipe 5 unchanged. At the same time, when the left gear 12 moves to the top of the right arc-shaped rack 15, it is in a state of being able to mesh with the right arc-shaped rack 15.

[0053] A guide rod 21 is fixedly arranged on the upper surface of the reversing plate 2, the top end of the guide rod 21 passes through the connecting plate 17, and a downward pressure spring 22 is arranged between the upper surface of the connecting plate 17 and the top end of the guide rod 21. The downward pressure spring 22 exerts a downward force on the connecting plate 17 by its elastic force.

[0054] Among them, a positioning rod 23 is fixedly installed at the bottom of one end of the connecting plate 17 corresponding to the handle, and positioning holes 24 are provided on the front and rear sides of the frame 1. The bottom end of the positioning rod 23 passes through the reversing table 2 and is inserted into one of the positioning holes 24. When the left gear 12 is at the highest position, the bottom end of the positioning rod 23 is located between the reversing table 2 and the frame 1 in the height direction.

[0055] Specifically, when the reversing platform 2 is in the initial state and rotated 180°, the positioning rod 23 cooperates with the positioning hole 24 to fix the reversing platform 2 on the frame 1 to prevent the reversing platform 2 from rotating on the frame 1. Furthermore, in the process of pushing the device as a whole forward, the handle can be used to adjust the forward direction of the device to adjust the walking trajectory of the device and move forward stably without pulling the handle backwards.

[0056] In the process of pulling the handle backward to make the left gear 12 rise, the lifting plate simultaneously drives the positioning rod 23 to move upward as a whole, so that the positioning rod 23 is pulled out from the positioning hole 24 to unlock the reversing table 2, so that the reversing table 2 is in a state of being able to rotate on the frame 1.

[0057] After the reversing table 2 rotates 180°, the lifting plate moves downward during the process of restoring the handle. At this time, not only the left gear 12 is reset downward to the lowest height, but also the bottom end of the positioning rod 23 is inserted downward into the positioning hole 24, so that the reversing table 2 is repositioned on the frame 1.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
