Description

Technical Field

[0001] The present utility model relates to the technical field of surface treatment, in particular to a production device for surface treatment of guardrails. Background Art

[0002] In the production and maintenance process of guardrails, surface painting treatment is a key process aimed at providing anti-corrosion and decorative effects. The traditional manual painting method is not only inefficient, but the uniformity of the paint is highly dependent on the technical level of the operating workers, which easily leads to problems such as uneven coating thickness, sagging or missing spraying, affecting product quality and service life. In addition, manual operation exposes workers to a paint mist environment for a long time, posing a potential threat to health. Although some automated painting equipment exists, they often have complex structures, high costs, or poor adaptability, making it difficult to flexibly process guardrail members of different sizes, especially those placed vertically.

[0017] Wherein, a rotary motor 401 is vertically mounted on the back of the paint spray guide frame 4 in a hanging manner, the rotating shaft of the rotary motor 401 is connected with a right-angled rocker arm 402 in a manner of rotating vertically forward, the end of the rocker arm 402 is rotatably mounted with a rocker wheel 403, and side slideways 404 are respectively arranged on the vertical side walls at the left and right ends of the inner frame of the paint spray guide frame 4.

[0018] Wherein, the spray painting rack 5 is provided with at least three vertically parallel spray painting annular pipes 501, the spray painting annular pipes 501 are of a "mouth"-shaped structure and are connected in parallel to the paint inlet connecting pipes 505 on the left and right sides, the inner side wall of each spray painting annular pipe 501 is uniformly provided with spray painting heads 502 at intervals, the to-be-treated guardrail is vertically positioned in the spray painting annular pipes 501, the left and right ends of the spray painting rack 5 are respectively provided with pulleys 503, the pulleys 503 are slidably mounted in the side slide grooves 404 of the spray painting guide rack 4, the back of the spray painting rack 5 is provided with two vertically parallel clamping plates 504, the rocking wheel 403 is slidably arranged between the two clamping plates 504, the rocking rod 402 rotates to drive the rocking wheel 403, and the rocking wheel 403 makes the spray painting rack 5 move vertically and reciprocally along the side slide grooves 404.

[0019] The functions and effects of each structure in the above content are further explained and described below, so that those skilled in the art can better understand the technical solution: the lifting cylinders 2 arranged at the left and right ends of the outer support frame 1 are used to control the vertical lifting of the spray painting guide rack 4, so as to adjust the spray painting height to adapt to guardrails of different sizes and realize flexible height adjustment. The spray painting guide rack 4 is of a rectangular structure, suspended by the lifting cylinders 2, and the spray painting rack 5 is slidably installed inside it, ensuring the stable movement of the spray painting rack 5; the rotating motor 401 arranged at the back of the spray painting guide rack 4 drives the spray painting rack 5 through the rocking rod 402 and the rocking wheel 403, and the side slide grooves 404 guide the vertical sliding of the spray painting rack 5, ensuring the accuracy of the spray painting process. The multiple spray painting annular pipes 501 arranged on the spray painting rack 5 are of a "mouth"-shaped structure and connected in parallel to the paint inlet connecting pipes 505, and the spray painting heads 502 uniformly distributed on the inner side of the spray painting annular pipes 501 can fully cover the surface of the guardrail to achieve uniform spray painting; the spray painting rack 5 slides in the side slide grooves 404 through the pulleys 503, and the clamping plates 504 arranged at its back cooperate with the rocking wheel 403 to convert the rotational motion of the rocking rod 402 into the vertical reciprocating motion of the spray painting rack 5, thereby enhancing the uniformity and efficiency of spray painting. The guard plate 3 arranged at the back of the outer support frame 1 provides safety protection, the transparent window 301 in the middle of the guard plate 3 facilitates the operator to observe the spray painting process, and the holding rod 302 at the back of the guard plate 3 is convenient for moving and operating the device. The bottom pulleys 101 at the four corners of the bottom of the outer support frame 1 are composed of four small wheels, which enhances the stability and mobility of the device and facilitates flexible positioning in the production environment. On the whole, the device realizes the automatic reciprocating motion of the spray painting rack 5 through the cooperative control of the lifting cylinders 2 and the rotating motor 401.

[0020] The working principle of this embodiment is as follows: During use, the operator first moves the device to the working position using the lever 302 and bottom pulley 101, and then vertically places the guardrail to be processed in the center of the paint spraying frame 5. After starting the device, the operator can control the extension and retraction of the lifting cylinders 2 at both ends of the outer support frame 1 according to the actual height of the guardrail, thereby driving the paint spraying guide frame 4 and the paint spraying frame 5 installed inside it to rise and fall as a whole, so that at least three paint spraying rings 501 on the paint spraying frame 5 can surround the effective processing section of the guardrail. When the painting operation begins, paint is transported through the paint inlet pipe 505 to each of the parallel paint spraying rings 501, and sprayed out by the paint spray heads 502 evenly distributed on the inner wall of the paint spraying rings 501. At the same time, the rotary motor 401 on the back of the paint spraying guide frame 4 starts, driving the right-angle rocker arm 402 at the front end of its shaft to rotate, and the rocker wheel 403 at the end of the rocker arm 402 then moves in a circular motion between the two parallel clamps 504 on the back of the paint spraying frame 5. Since the rocker wheel 403 is constrained between the two clamping plates 504, its circular motion is converted into a continuous pushing and pulling action on the clamping plates 504, thereby driving the entire paint spraying frame 5 to make a stable vertical reciprocating motion along the side slide 404 on the paint spraying guide frame 4 via the pulleys 503 at both ends. This reciprocating motion ensures that the paint spray head 502 can perform a uniform up-and-down scanning spray on the stationary vertical guardrail, effectively avoiding missed sprays or uneven coating. Throughout the process, the operator can observe the internal painting status through the transparent viewing window 301 on the guard plate 3, while the guard plate 3 itself plays a safety protection role by isolating paint mist. Finally, through the combination of the height preset of the lifting cylinder 2 and the reciprocating motion of the paint spraying frame 5 driven by the rotary motor 401, efficient, uniform, and automated painting treatment of the guardrail surface is achieved.
