[0022] 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.

[0023] 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.

[0024] Example 1: As Figure 1 - Figure 4 As shown, this embodiment provides a bridge railing paint repair device, including a mobile vehicle 1, a fixed frame 3 fixedly connected to one side of the mobile vehicle 1, a paint repair mechanism 2 installed on one side of the fixed frame 3, and a collection mechanism 4 installed on the inner side of the fixed frame 3.

[0025] The paint touch-up mechanism 2 includes a second connecting pipe 24, multiple first rotating rods 212 and multiple second rotating rods 213. There are two second connecting pipes 24, which are fixed inside the fixed frame 3. The second connecting pipes 24 are fixedly connected to a third connecting pipe 26. One end of the third connecting pipe 26 is fixedly connected to a paint touch-up nozzle 27. A connecting block 28 is fixedly connected to one side of the paint touch-up nozzle 27. The ends of the multiple first rotating rods 212 are hinged together, and the ends of the multiple second rotating rods 213 are hinged together. The middle parts of the corresponding first rotating rods 212 and second rotating rods 213 are hinged together. The hinged parts of the first rotating rods 212 and second rotating rods 213 are connected to the connecting block 28.

[0026] One end of the first rotating rod 212 at the bottom is rotatably connected to one side of the fixed frame 3. One end of the second rotating rod 213 at the bottom is rotatably connected to a sliding block 215. A guide rail 29 is slidably connected to the outside of the sliding block 215. One end of the guide rail 29 is fixedly connected to one side of the fixed frame 3. One end of the sliding block 215 is fixedly connected to a moving block 210. One end of the moving block 210 is fixedly connected to an electric push rod 211. One side of the electric push rod 211 is fixedly connected to one side of the fixed frame 3.

[0027] In this embodiment, slots 214 are provided on both sides of the fixed frame 3, and the connecting block 28 is slidably installed in the slots 214; an electric control valve 25 is installed on the third connecting pipe 26.

[0028] In this embodiment, one end of each of the two second connecting pipes 24 is connected to and passes through one side of the fixed frame 3. One end of the second connecting pipe 24 is fixedly connected to the paint pump 23. One end of the paint pump 23 is fixedly connected to the first connecting pipe 22. One end of the first connecting pipe 22 is fixedly connected to the placement box 21. The placement box 21 is fixedly installed on the mobile vehicle 1. The top of the placement box 21 is fixedly connected to the paint pump 23.

[0029] Paint pump 23 operates, drawing paint from inside storage tank 21, which is then sprayed out from touch-up nozzle 27 through first connecting pipe 22, second connecting pipe 24, and third connecting pipe 26 to touch up the paint on the guardrail. Electric push rod 211 drives moving block 210, and sliding block 215 slides inside guide rail 29, causing it to move linearly. This drives the connected second rotating rod 213 to rotate. The second rotating rod 213 and the first rotating rod 212 rotate crosswise at their midpoints, connecting pairs of second rotating rods 213 and pairs of first rotating rods 212, thus enabling multiple first rotating rods... When the first rotating rod 212 and the second rotating rod 213 rotate, the middle connection between the first rotating rod 212 and the second rotating rod 213 moves, and the connecting block 28 moves accordingly. The connecting block 28 slides inside the slot 214, and the fixed connecting block 28 makes linear motion, which drives the position of the touch-up paint nozzle 27 to move. The touch-up paint nozzle 27 at different positions can be made to work by controlling the closure of the electric control valve 25, so as to prevent the touch-up paint nozzle 27 from spraying too much paint on the guardrail when it is too close. By adjusting the position of the touch-up paint nozzle 27, the guardrail at different heights can be touched up. The position of the touch-up paint nozzle 27 is arranged according to the height of the guardrail to ensure full coverage.

[0030] Example 2: Figure 1 and Figure 4 As shown, this embodiment has a structure that is basically the same as that of embodiment one. This embodiment also includes a collection mechanism 4, which includes a collection frame 41. A plug-in block 42 is inserted into one side of the collection frame 41. One end of the plug-in block 42 is fixedly connected to one side of the fixed frame 3. A sleeve frame 45 is sleeved on the outside of the plug-in block 42. One end of the sleeve frame 45 is fixedly connected to one side of the collection frame 41. A plug-in rod 43 is provided on one side of the sleeve frame 45. One end of the plug-in rod 43 passes through the sleeve frame 45 and the plug-in block 42 in sequence. A spring 44 is sleeved on the outside of the plug-in rod 43. The spring 44 is disposed between the sleeve frame 45 and the plug-in rod 43.

[0031] Excess paint droplets sprayed from the paint nozzle 27 fall into the collection frame 41 inside the guardrail. By pulling the plug rod 43 outward, the spring 44 extends and the plug rod 43 moves to separate from the plug block 42. The socket frame 45 and the collection frame 41 are then removed outward, thereby separating the plug block 42 from the collection frame 41. The paint inside the collection frame 41 is then processed, and the paint that is not attached to the guardrail is recycled and reused, reducing paint waste and environmental pollution.

[0032] The device is used and operates as follows: The electric push rod 211 moves the moving block 210, which in turn rotates the connected second rotating rod 213. This causes multiple first rotating rods 212 and second rotating rods 213 to rotate. The middle connection between the first rotating rods 212 and second rotating rods 213 moves, causing the connecting block 28 to move accordingly. This moves the position of the touch-up paint nozzle 27. The paint pump 23 operates, drawing paint from inside the storage box 21 through the first connecting pipe 22, the second connecting pipe 24, and the third connecting pipe 26 before spraying it from the touch-up paint nozzle 27 to touch up the guardrail. Excess paint sprayed from the nozzle 27 falls into the collection frame 41. By pulling the plug rod 43 outwards, the spring 44 extends, and the plug rod 43 moves to separate from the plug block 42. This allows the socket frame 45 and collection frame 41 to be removed, separating the plug block 42 from the collection frame 41 and allowing the paint inside the collection frame 41 to be treated.

[0033] 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.
