[0003] Existing concrete anti-corrosion coating spraying equipment requires manual operation, moving and spraying simultaneously. As a result, it is difficult to control the spraying speed and the distance between the spraying position and the concrete surface, leading to an unstable spraying trajectory, low spraying efficiency of the anti-corrosion coating, and affecting the overall uniformity of the spraying on the concrete surface. Utility Model Content

[0004] The purpose of this utility model is to provide a concrete anti-corrosion coating spraying device to solve the problems mentioned in the background art, which require manual operation to move and spray at the same time. Therefore, it is difficult to control the spraying speed and the distance between the spraying position and the concrete surface, resulting in an unstable spraying trajectory, low spraying efficiency of anti-corrosion coating, and affecting the uniformity of the overall spraying on the concrete surface.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete anti-corrosion coating spraying device, comprising a mobile vehicle and a spraying mechanism. The mobile vehicle includes a fixed base and a coating storage tank, the coating storage tank being located above the fixed base. It also includes a slide rail and a spraying range control cover. The slide rail is connected to one end of the fixed base. The spraying mechanism includes a mobile base and a nozzle assembly. The coating storage tank supplies material to the nozzle assembly.

[0007] Preferably, the nozzle assembly includes a connector, a housing, and a nozzle, wherein the housing is disposed on the side of the connector and the nozzle is mounted on the side of the housing.

[0008] Preferably, a through hole is provided on the side of the cover body that connects to the nozzle assembly, and the box body is laterally slidably connected to the through hole position.

[0009] Preferably, the nozzle assembly further includes protrusions and rollers. Protrusions are provided on the upper and lower surfaces of the housing body, and rollers are mounted on the protrusions. Grooves are provided on both the upper and lower surfaces of the through hole, and the rollers are correspondingly connected to the grooves.

[0010] Preferably, the spraying mechanism further includes a telescopic kit and a first linear driver. The upper part of the movable end of the telescopic kit is fixedly connected to a nozzle assembly, and the lower part of the fixed end of the telescopic kit is fixedly connected to a movable base.

[0013] Preferably, the inner edge of the surrounding border is provided with a raised edge near the edge.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the arrangement of a slide rail, a nozzle assembly, and a second linear actuator, enables the nozzle assembly to move and spray at the same height within a certain area of ​​the concrete surface to be sprayed. Since the slide rail and the moving vehicle remain stationary during the spraying process, and the distance between the nozzle assembly and the concrete surface remains constant during the movement, and the second linear actuator causes the nozzle assembly to move at a uniform speed, the anti-corrosion coating sprayed by the nozzle assembly within the area that it can move on the slide rail is uniform and has a stable trajectory. Furthermore, the height of the nozzle assembly can be adjusted to perform transverse spraying for other height areas.

[0015] 2. This utility model, through the design of the cover, ensures that the area sprayed by the nozzle moving on the slide rail matches the area framed by the opening of the cover. The size of the opening of the cover is the area sprayed by the nozzle in one lateral movement. Therefore, the cover can serve as a component for visually observing the position of the area after spraying, indicating the degree of height adjustment of the nozzle assembly when spraying at the next height position, and also indicating the distance the moving vehicle and slide rail move when spraying the next area. This ensures that the spraying range can be connected after adjusting the position of the nozzle assembly for each spraying, reducing repeated spraying or missed spraying, and improving the uniformity of the overall spraying of the concrete surface.

[0025] 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.

[0026] One embodiment of this utility model provides: a concrete anti-corrosion coating spraying device, such as... Figure 1 As shown, it includes a mobile vehicle body 1, a slide rail 2, a spraying mechanism 3, a spraying range control cover 4, and casters 5.

[0027] like Figure 1 and Figure 2 As shown, the mobile vehicle 1 includes a fixed base 11 and a paint storage tank 12. The paint storage tank 12 is located above the fixed base 11. A slide rail 2 is connected to one end of the fixed base 11. The spraying mechanism 3 is laterally slidably connected to the slide rail 2. Universal wheels 5 are provided below both the fixed base 11 and the slide rail 2. A push handle 111 is installed on the fixed base 11. Before using this device to spray anti-corrosion coating onto concrete, push the push handle 111 to position the mobile vehicle 1 and the slide rail 2 to the position to be sprayed, so that the slide rail 2 is parallel to the concrete surface to be sprayed. This ensures that during spraying, the spraying mechanism 3 moves back and forth laterally on the slide rail 2, and the spraying distance of the spraying mechanism 3 on the concrete surface remains consistent.

[0028] like Figure 3 As shown, the spraying mechanism 3 includes a movable base 31, a telescopic kit 32, a first linear driver 33, a nozzle assembly 34, and a second linear driver 35.

[0029] like Figure 4 As shown, the movable seat 31 is laterally slidably connected above the slide rail 2. The body of the second linear actuator 35 is fixedly connected to the fixed seat 11, and the output end of the second linear actuator 35 is fixedly connected to the extension 312 on the side of the movable seat 31. A pulley 311 is provided at the bottom of the movable seat 31, and the pulley 311 is correspondingly connected to the slide rail 2. When the spraying mechanism 3 moves back and forth laterally on the slide rail 2, the second linear actuator 35 provides power to drive the movable seat 31 to move. When the movable seat 31 moves, the pulley 311 below it rolls inside the slide rail 2 to maintain the stability of the movement process.

[0030] Compared to traditional concrete anti-corrosion coating spraying devices, this device, with its sliding rail 2 and second linear actuator 35, allows the nozzle assembly 34 to move and spray at the same height within a certain area of ​​the concrete surface to be sprayed. Since the sliding rail 2 and the moving vehicle 1 remain stationary during the spraying process, and the distance between the nozzle assembly 34 and the concrete surface remains constant during the movement, the second linear actuator 35 causes the nozzle assembly 34 to move at a uniform speed. Therefore, within the area that the nozzle assembly 34 can move on the sliding rail 2, the anti-corrosion coating sprayed by this device is uniform and has a stable trajectory, replacing the traditional method of manually pushing the moving vehicle 1 while spraying, thus improving the spraying effect.

[0031] like Figure 3 As shown, the nozzle assembly 34 is vertically slidably connected to the movable base 31. The nozzle assembly 34 is fixedly connected to the upper part of the movable end of the telescopic kit 32, and the lower part of the fixed end of the telescopic kit 32 is fixedly connected to the movable base 31. The body of the first linear actuator 33 is fixed to the movable base 31, and the output end of the first linear actuator 33 is fixedly connected to the movable end of the telescopic kit 32. The first linear actuator 33 drives the movable end of the telescopic kit 32. After the nozzle assembly 34 completes spraying on the concrete surface of the same height within the area that can move on the slide rail 2, the height of the nozzle assembly 34 can be adjusted to perform horizontal spraying on other height areas. This process is repeated for each height area, thereby completing the spraying of the anti-corrosion coating on the entire concrete surface of that area. When spraying the next area, the movable vehicle 1 can be moved to the next corresponding position, and the operation can be repeated. When adjusting the height of the nozzle assembly 34, the first linear actuator 33 drives the telescopic kit 32 to lengthen or shorten, thereby changing the height of the nozzle assembly 34.

[0032] like Figure 5 As shown, the nozzle assembly 34 includes a connector 341, a housing 342, a nozzle 343, a protrusion 344, and a roller 345. The housing 342 is disposed on the side of the connector 341, and the nozzle 343 is mounted on the side of the housing 342.

[0033] like Figure 2 As shown, the paint storage tank 12 supplies paint to the nozzle assembly 34 through the paint output pump 13. The paint output pump 13 is connected to one end of the output pipe 131, and the other end of the output pipe 131 passes into the box body 342 and is connected to the nozzle 343.

[0034] like Figure 6 As shown, the spray range control cover 4 includes a bracket 41 and a cover body 42.

[0035] The cover 42 is connected to the nozzle assembly 34. The cover 42 is connected above the slide rail 2 via a bracket 41. The bracket 41 includes a movable support frame 411 and a fixed support frame 412. The movable support frame 411 and the fixed support frame 412 are vertically inserted together. One end of the movable support frame 411 that is not connected to the fixed support frame 412 is fixedly connected to the slide rail 2. The other end of the fixed support frame 412 that is not connected to the movable support frame 411 is fixedly connected to the connecting seat 341 of the nozzle assembly 34. When the height of the nozzle assembly 34 changes, the movable support frame 411 of the bracket 41 changes height synchronously with the nozzle assembly 34, thereby ensuring that the cover 42 installed and connected to the nozzle assembly 34 also changes height synchronously when the height of the nozzle assembly 34 changes.

[0036] The nozzle assembly 34 is laterally slidably connected inside the housing 42. A through hole 421 is provided on the side of the housing 42 where the nozzle assembly 34 is connected. The housing 342 is laterally slidably connected at the through hole 421. Rollers 345 are mounted on the protrusion 344. Grooves 4211 are provided on both the upper and lower surfaces of the through hole 421, and the rollers 345 are correspondingly connected to the grooves 4211. The side of the housing 42 facing the nozzle assembly 34 is open. As the nozzle assembly 34 moves laterally with the moving base 31, it also moves laterally relative to the housing 42 at the through hole 421.

[0037] When the push handle 111 is pushed to position the moving vehicle 1 and the slide rail 2, the open part of the cover 42 is kept close to the concrete surface. Since the open side of the cover 42 is parallel to the direction of the slide rail 2, it is easy to determine that the position of the moving vehicle 1 on the slide rail 2 is parallel to the concrete surface by the cover 42 being close to the concrete surface. Therefore, the cover 42 can be used to help position the device to be sprayed.

[0038] During the spraying process, the moving vehicle 1 and the slide rail 2 remain stationary, as does the cover 42, which is always close to the concrete surface. When the nozzle 343 sprays paint, the cover 42 provides isolation, resulting in a regular sprayed area that is less likely to exceed the defined area. At the same time, the cover 42 reduces the spread of the sprayed paint, thus minimizing the impact of paint spread on the working environment.

[0039] The area sprayed by the nozzle 343 as it moves on the slide rail 2 matches the area framed by the opening of the cover body 42. The size of the opening of the cover body 42 is the area sprayed by the nozzle 343 in one lateral movement. Therefore, the cover body 42 can serve as a component for visually observing the position of the area after spraying in advance, providing a prompt for the height adjustment of the nozzle assembly 34 when spraying at the next height position, and also providing a prompt for the moving distance between the moving vehicle 1 and the slide rail 2 when spraying the next area. This ensures that the spraying range can be connected after adjusting the position of the nozzle assembly 34 in each spraying, reducing the situation of repeated spraying or missed spraying, and improving the uniformity of the overall spraying of the concrete surface.

[0040] like Figure 7 and Figure 8 As shown, the open edge of the cover 42 has a surrounding frame 422. The cross-section of the frame 422 material is U-shaped. The outer ring of the surrounding frame 422 connects to the cover 42. A hole is opened at the bottom of the outer ring of the frame 422, communicating with the recycling box 4221 below it. During the spraying process of the nozzle 343, due to the obstruction of the cover 42, some of the sprayed paint will fall onto the frame 422. The paint collected above and on both sides of the frame 422 will flow to the bottom of the frame 422 and eventually collect in the recycling box 4221. The recycling box 4221 is connected to the paint storage tank 12. The lower end of the recycling box 4221 is connected to one end of the recycling pipe 141, and the other end of the recycling pipe 141 is connected to the paint recycling pump 14. The paint recycling pump 14 recycles paint from the paint storage tank 12. A raised edge 4222 is provided on the upper inner ring of the surrounding frame 422 near the edge. This device collects excess paint at the frame 422 for secondary recycling, saving energy and protecting the environment, reducing paint waste.

[0041] The above are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics in the solutions has not been described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
