Description

Technical Field

[0001] This utility model relates to the field of pipeline coating technology, specifically a device for spraying anti-corrosion coatings for pipeline outer wall corrosion protection. Background Technology

[0002] Anti-corrosion coatings are generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, and are an essential type of paint. Conventional anti-corrosion coatings provide corrosion protection for metals under normal conditions, extending the service life of non-ferrous metals. Heavy-duty anti-corrosion coatings, on the other hand, can be used in relatively harsh corrosive environments and offer a longer protection period than conventional anti-corrosion coatings.

[0003] Pipeline corrosion protection is an important aspect of pipeline use and maintenance, especially for open-air pipelines. Although anti-corrosion paint is applied to the outer wall of the pipeline during installation, after long-term use, the paint is eroded by factors such as sunlight, rain, snow, and sand, resulting in damage and loss of protection. Therefore, it is necessary to repaint the outside of the pipeline frequently. However, most existing painting equipment is only used on pipelines that have not yet been installed, while pipelines that have already been laid still require manual spraying, which is labor-intensive and involves a large workload. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies where manual spraying is labor-intensive, and to provide a device for spraying anti-corrosion coatings for the outer wall of pipelines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for anti-corrosion coating on the outer wall of a pipeline, comprising a base plate, two support plates on the top of the base plate, the two support plates being symmetrically arranged vertically, and spraying pipes fixedly connected to opposite sides of the two support plates, and a plurality of linearly arranged nozzles fixedly connected to opposite sides of the spraying pipes, a paint bucket and a paint pump fixedly connected to the top of the base plate, the paint bucket and the paint pump being connected, and a delivery pipe fixedly connected to the paint pump and the spraying pipes, casters fixedly connected to the bottom of the base plate near the four corners, and push rods fixedly connected to the base plate.

[0006] As described above, a telescopic cylinder is fixedly connected to the base plate, the support plate is a right-angled triangle, the spray pipe is located on the hypotenuse side of the support plate, and the telescopic end and cylinder body of the telescopic cylinder are fixedly connected to the right-angled side of the adjacent support plate, respectively.

[0007] As described above, the support plate has a groove on its inclined side, a slide rail is slidably connected in the groove, and the spray pipe is fixedly connected to the slide rail. A rotary cylinder is fixedly connected to the support plate, and the rotary cylinder is kinetically connected to the slide rail.

[0008] As described above, the support plate has a cavity that communicates with the slide groove, the rotary cylinder is fixedly connected in the cavity, the output end of the rotary cylinder is fixedly connected to a gear, and the slide rail is fixedly connected to a rack, which meshes with the gear.

[0009] As described above, the support plate has a fixing plate on its inclined side, the fixing plate is fixedly connected to the slide rail, the spray pipe is fixedly connected to the fixing plate, and the front and rear sides of the spray pipe are respectively provided with fixing pipes and ultraviolet lamps.

[0010] As described above, an air pump is fixedly connected to the base plate, an air supply pipe is fixedly connected between the air pump and the fixed pipe, and several nozzles are fixedly connected to the fixed pipe. Both the air supply pipe and the delivery pipe are flexible hoses.

[0011] As mentioned above, the top of the paint bucket is movably connected to a cover plate, and the cross-section of the slide rail and the slide groove is I-shaped.

[0012] Compared with existing technologies, this anti-corrosion coating spraying device for pipeline external walls has the following advantages:

[0013] I. This utility model uses two support plates to support two spraying pipes located on the same side of a pipeline, with the two spraying pipes distributed vertically. Then, the device can be moved along the pipeline by a push rod and casters, thereby spraying one half of the outer wall of the pipeline. After that, spraying is carried out again on the other side of the pipeline to complete the anti-corrosion paint spraying of the outer wall of the pipeline. The structure is simple and easy to operate, which can effectively replace manual spraying, reduce labor intensity, and improve work efficiency.

[0014] II. This utility model is equipped with a telescopic cylinder, which pushes the upper support plate to move up and down, thereby adjusting the distance between the two support plates. A rotary cylinder, gear and rack are installed in the support plate. The rotary cylinder drives the gear to rotate back and forth, thereby pushing the rack to drive the spray pipe to move back and forth, so as to spray the outer wall of pipes of different diameters.

[0015] Third, by setting a fixed pipe with a nozzle on it and connecting an air pump to the fixed pipe, air is pumped into the fixed pipe and sprayed out from the nozzle, which can remove dust and other impurities on the outer wall of the pipe and prevent impurities from interfering with the incomplete coverage of the anti-corrosion paint.

[0022] 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.

[0023] like Figure 1-4 As shown, this utility model provides a technical solution: a spraying device for anti-corrosion coating on the outer wall of a pipeline, including a base plate 1, two support plates 2 on the top of the base plate 1, the two support plates 2 are symmetrically arranged vertically, and spraying pipes 3 are fixedly connected to opposite sides of the two support plates 2. Several linearly arranged nozzles are fixedly connected to opposite sides of the spraying pipes 3. A paint bucket 5 and a paint pump 4 are fixedly connected to the top of the base plate 1. The paint bucket 5 and the paint pump 4 are connected, and a delivery pipe 11 is fixedly connected between the paint pump 4 and the spraying pipes 3. Universal wheels 10 are fixedly connected to the bottom of the base plate 1 near the four corners, and push rods 13 are fixedly connected to the base plate 1.

[0024] According to the overall structure of the device, when in use, the device can be powered by an external battery. The device can be moved to one side of the pipeline by the rollers, so that the upper and lower support plates 2 and the spray pipe 3 are located on the upper and lower sides of the pipeline. Then, anti-corrosion paint is poured into the paint bucket 5, and the paint pump 4 is started. The paint pump 4 pumps the anti-corrosion paint in the paint bucket 5 into the spray pipe 3 through the delivery pipe 11, and sprays it on the outer wall of the pipeline through the nozzle. The device can be moved along the pipeline by the push rod 13, thereby covering half of the outer wall of the pipeline. Then the device is moved to the other side of the pipeline and the above steps are continued to spray the other side of the pipeline.

[0025] like Figure 2 As shown, a telescopic cylinder 7 is fixedly connected to the base plate 1, the support plate 2 is a right triangle, the spray pipe 3 is located on the hypotenuse of the support plate 2, and the telescopic end and cylinder body of the telescopic cylinder 7 are fixedly connected to the right-angled side of the adjacent support plate 2 respectively.

[0026] By setting up a triangular support plate 2 and placing the spray pipe 3 on the inclined side of the support plate 2, the spray pipe 3 has a larger spraying range. The upper support plate 2 can be moved up and down by the telescopic cylinder 7, thereby adjusting the interval between the two support plates 2, which is convenient for pipes of different diameters.

[0027] like Figure 4 As shown, a groove is provided on the inclined side of the support plate 2, and a slide rail 15 is slidably connected in the groove. The spray pipe 3 is fixedly connected to the slide rail 15. A rotary cylinder 16 is fixedly connected to the support plate 2, and the rotary cylinder 16 is connected to the slide rail 15 in a transmission connection. A cavity is provided on the support plate 2 that communicates with the groove. The rotary cylinder 16 is fixedly connected in the cavity. A gear 17 is fixedly connected to the output end of the rotary cylinder 16. A rack 18 is fixedly connected to the slide rail 15, and the rack 18 meshes with the gear 17.

[0028] The rotary cylinder 16 drives the gear 17 to rotate back and forth. When the gear 17 rotates, it pushes the slide rail 15 to move back and forth in the slide groove through the rack 18, thereby driving the spray pipe 3 to move back and forth, thereby adjusting the spray coverage of the spray pipe 3 to facilitate the use of pipes with different diameters.

[0029] like Figure 3 As shown, a fixing plate 14 is provided on the inclined side of the support plate 2. The fixing plate 14 is fixedly connected to the slide rail 15. The spray pipe 3 is fixedly connected to the fixing plate 14. The front and rear sides of the spray pipe 3 are respectively provided with fixing pipes 9 and ultraviolet lamps 8. An air pump 6 is fixedly connected to the base plate 1. An air supply pipe 12 is fixedly connected between the air pump 6 and the fixing pipe 9. Several nozzles are fixedly connected to the fixing pipe 9. Both the air supply pipe 12 and the delivery pipe 11 are flexible hoses.

[0030] Air is supplied to the fixed pipe 9 through the air pump 6 and the air supply pipe 12, and the gas is sprayed out from the nozzle to remove dust and other impurities from the outer wall of the pipe, preventing interference with the spraying of the anti-corrosion paint. The anti-corrosion paint is irradiated by the ultraviolet lamp 8 after spraying, so that it dries quickly. The fixed pipe 9 and the ultraviolet lamp 8 move synchronously with the spraying pipe 3 through the fixed plate 14. The connection through the hose facilitates the delivery of anti-corrosion paint and gas during the movement of the fixed pipe 9 and the spraying pipe 3.

[0031] like Figure 1 , 3 As shown, a cover plate is movably connected to the top of the paint bucket 5, and the cross-section of the slide rail 15 and the slide groove is I-shaped.

[0032] The paint bucket 5 is covered by a cover plate to prevent the anti-corrosion paint inside from splashing out. The slide rail 15 is limited by the I-shaped cross-section groove to prevent it from slipping in the vertical direction, ensuring that the rack 18 and the gear 17 mesh.

[0033] Working principle: During use, the device can be powered by an external battery. The device can be moved to one side of the pipeline using rollers, positioning the upper and lower support plates 2 and the spray pipe 3 on either side of the pipeline. Then, anti-corrosion paint is poured into the paint bucket 5, and the paint pump 4 is started. The paint pump 4 pumps the anti-corrosion paint from the paint bucket 5 into the spray pipe 3 through the delivery pipe 11, and sprays it onto the outer wall of the pipeline through the nozzle. The push rod 13 can push the device along the pipeline, thus covering half of the outer wall of the pipeline. The device is then moved to the other side of the pipeline, and the above steps are repeated to spray the other side. During use, the cylinder is activated to raise the upper support plate 2, allowing for use on larger pipelines. The rotary cylinder 16 is activated, driving the gear 17 to push the rack 18, which in turn moves the slide rail 15 back and forth, thus moving the spray pipe 3 back and forth, resulting in a larger spray coverage area suitable for different pipeline applications.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
