Description

Technical Field

[0001] This utility model relates to the technical field of road construction, and in particular to a high-efficiency coating device for concrete walls. Background Technology

[0002] Reinforced concrete crash barriers are the main type of crash guardrail for highway bridges, with a design service life of typically 15 years, and generally using low-grade concrete. Due to the special structure of the crash barrier, large pores are easily formed inside the concrete during construction. Furthermore, because they are exposed to the elements for extended periods, problems such as carbonation and water seepage frequently occur, leading to prominent early defects such as cracking, spalling, and steel corrosion, becoming common problems in bridge operation and maintenance.

[0003] To address the aforementioned issues, paint is typically applied as a protective layer to the surface of the crash barrier to improve its corrosion resistance and structural safety. However, existing automated paint application devices are generally suitable for relatively smooth surfaces. For irregular structures, manual touch-ups are required, resulting in a cumbersome workflow, poor operability, and low painting efficiency, which impacts construction progress. Utility Model Content

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Reference Figures 1-4 This embodiment provides a high-efficiency coating device for concrete walls, comprising: Support plate 1 is movably mounted on the ground; The fixed bracket 11 is fixedly installed on the support plate 1; The brush holder 12 is oscillatingly mounted on the fixed bracket 11. The end of the brush holder 12 is configured as a forked structure. Multiple brush roller clamping mechanisms are provided on the forked structure of the brush holder 12. A switch control box is provided on the brush holder 12. Two brush rollers 13 are rotatably mounted on the brush holder 12, and the brush rollers 13 are rotatably engaged with the brush roller clamping mechanism. Both hinged seats 14 are fixedly installed on the support plate 1; Two telescopic sleeves 15 are respectively oscillatingly mounted on two hinge seats 14. A telescopic rod 16 is slidably inserted into each telescopic sleeve 15. The top of the telescopic rod 16 is hinged to the main body of the paint rack 12. A drying mechanism, mounted on support plate 1, is used to accelerate the drying speed of the coating. In this embodiment, the support plate 1, which is movable and set on the ground, is pushed to the area of ​​the crash barrier to be painted. The operator swings the paint rack 12 up and down, causing it to swing around the fixed bracket 11, which in turn causes the two brush rollers 13 to swing up and down. The brush roller clamping mechanism continuously provides elasticity, ensuring that the brush rollers maintain uniform contact on uneven surfaces and avoiding missed areas or local over-painting. The drying mechanism set on the support plate 1 is activated simultaneously, blowing a uniform airflow into the area that has just been painted, accelerating the air circulation on the paint surface, reducing the impact of ambient temperature and humidity on paint film formation, and realizing continuous painting and drying operations. This high-efficiency concrete wall painting device, through the swing installation of the paint rack, the cooperation of the telescopic sleeve and telescopic rod, and the brush roller clamping mechanism, enables the brush rollers to closely fit the irregular surface of the crash barrier for painting, reducing the amount of manual touch-up work and improving the operability of construction. The drying mechanism of this device accelerates the paint drying speed, shortens the construction cycle, and thus improves painting efficiency.

[0018] As a preferred embodiment of the above technical solution, such as Figure 1 and Figure 3 As shown, the drying mechanism includes: Air pump 21 is fixedly installed on support plate 1, and air pump 21 is electrically connected to switch control box; The gas supply pipe 22 is connected to the output end of the gas pump 21; The diversion pipe 23 is fixedly installed on the bifurcation structure of the brush holder 12. A main control valve 24 is connected to the diversion pipe 23. The main control valve 24 is connected to the air supply pipe 22. Multiple air outlets are provided on the diversion pipe 23. In this embodiment, after the air pump 21 is started, it draws in air from the surrounding environment and pressurizes it. The pressurized air enters the air supply pipe 22 through its output end, and the air supply pipe 22 stably transmits the high-pressure air to the main control valve 24. The main control valve 24 adjusts the airflow size and on / off state of the flow into the diversion pipe 23 according to preset parameters or operator control. When the main control valve 24 is open, the high-pressure air enters the diversion pipe 23, and the diversion pipe 23 evenly distributes the airflow to multiple air outlets provided thereon. The multiple air outlets simultaneously blow airflow onto the surface of the crash barrier after the paint has been applied. The airflow acts on the paint on the surface of the crash barrier, accelerating the evaporation of the solvent in the paint, thereby making the paint dry quickly, shortening the construction cycle, and improving construction efficiency.

[0019] Specifically, such as Figure 3 As shown, each air outlet of the split pipe 23 is connected to an air jet valve 25; In this embodiment, since there may be inconsistencies in the coating thickness and local humidity differences on the surface of the reinforced concrete crash barrier, the air jet valve 25 installed at each air outlet can be independently adjusted for different situations. It can precisely control the airflow of each air outlet according to actual needs, increase the drying force for areas with thicker coating or difficult drying, and decrease the drying force for areas with thinner coating or faster drying, so as to ensure that the coating on the entire surface of the crash barrier can be dried evenly and improve the coating quality.

[0020] More specifically, such as Figure 3 As shown, a control valve cylinder 26 is oscillatingly mounted on the diverter pipe 23, and the output end of the control valve cylinder 26 is hinged to the valve stem of the main control valve 24. In this embodiment, the opening of the main control valve 24 can be automatically adjusted by the control valve cylinder 26, so as to accurately control the total amount of airflow entering the diversion pipe 23 according to different construction conditions and requirements. The operator only needs to send a control signal to the control valve cylinder 26 through the switch control box to adjust the opening of the main control valve 24, without having to manually operate the main control valve 24, thus improving the convenience of operation.

[0021] Furthermore, such as Figure 1 As shown, a support 27 is rotatably mounted on the fixed bracket 11, and the support 27 is used to support the gas pipeline 22; In this embodiment, the support unit 27 can automatically adjust its angle according to the stress on the gas pipeline, providing stable support for the gas pipeline, preventing damage to the gas pipeline due to excessive deformation, extending the service life of the gas pipeline, and reducing equipment maintenance costs.

[0022] Furthermore, such as Figure 4 As shown, the brush roller clamping mechanism includes: The top bracket 31 is fixedly installed on the bifurcated structure of the paint rack 12; The bearing slider 32 is slidably disposed in the top clamping bracket 31, and the brush roller 13 is rotatably engaged with the bearing slider 32. The push rod 33 is inserted and mounted on the top clamping bracket 31; Spring 34 is disposed between bearing slider 32 and push rod 33; In this embodiment, when the brush roller 13 contacts the surface of the anti-collision wall, the anti-collision wall generates a reaction force on the brush roller 13. This reaction force is transmitted to the bearing slider 32 through the brush roller 13, causing the bearing slider 32 to slide in the clamping bracket 31 towards the push rod 33. During the sliding process of the bearing slider 32, the spring 34 is compressed, and the spring 34 undergoes elastic deformation and stores elastic potential energy. As the spring 34 is compressed, the elastic force it generates gradually increases. This elastic force, through the bearing slider 32, reacts on the brush roller 13, causing the brush roller 13 to press tightly against the surface of the anti-collision wall. As the coating device moves along... When painting on the surface of the crash barrier, the irregular shape of the surface results in varying degrees of protrusion and depression at different locations. The brush roller clamping mechanism automatically adjusts according to the surface undulations. When encountering a protrusion, the brush roller 13 pushes the bearing slider 32 to further compress the spring 34, increasing the pressure on the crash barrier surface. When encountering a depression, the elastic force of the spring 34 pushes the bearing slider 32 and the brush roller 13 outward, ensuring that the brush roller 13 always maintains close contact with the crash barrier surface, ensuring that the paint can be evenly applied to the crash barrier surface, thus improving painting efficiency and quality.

[0023] Furthermore, the push rod 33 is threaded onto the clamping bracket 31 to adjust the elastic force of the spring 34; In this embodiment, the threaded insertion of the top rod 33 allows the operator to flexibly adjust the elastic force of the spring 34 according to the specific characteristics of the crash barrier, thereby enabling the brush roller 13 to apply appropriate pressure to the surface of the crash barrier, ensuring good coating results under various working conditions and improving the versatility of the device.

[0024] Furthermore, such as Figure 1 As shown, four omnidirectional casters 17 are provided at the bottom of the support plate 1; In this embodiment, the four omnidirectional casters 17 enable the high-efficiency concrete wall coating device to move freely and flexibly on the construction site, quickly move the device to different construction positions, improve the flexibility of construction, and adapt to various complex construction site environments.

[0025] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
