[0024] 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.
[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0026] Example 1
[0027] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a pipeline anti-corrosion coating spraying device, including...
[0028] The housing mechanism 100 includes a support housing 101, a motor 102 fixedly installed on the side wall of the support housing 101, a partition 103 fixedly installed in the inner cavity of the housing mechanism 100, a slide groove 104 provided on the side wall of the support housing 101, and a closing assembly 105 provided on the top of the support housing 101.
[0029] The spraying mechanism 200 includes a support rod 201 fixedly installed on the inner wall of the bearing housing 101, a spray pipe 202 fixedly installed on the side wall of the support rod 201, a drive shaft 203 connected to the inner cavity of the bearing housing 101 via a bearing, a drive wheel 204 fixedly installed at the end of the drive shaft 203, an auxiliary component 205 disposed in the inner cavity of the bearing housing 101, and an internal spraying component 206 disposed on the side wall of the partition 103.
[0030] Specifically, the closing assembly 105 includes a hydraulic cylinder 105a fixedly installed on the top of the bearing housing 101, and a connecting block 105b fixedly installed on the end of the hydraulic cylinder 105a. The closing assembly 105 also includes a movable door 105c fixedly installed on the side wall of the connecting block 105b, and a slide rail 105d fixedly installed on the side wall of the movable door 105c.
[0031] Furthermore, the side wall of the slide rail 105d is movably connected to the inner wall of the slide groove 104, ensuring smooth movement of the movable door 105c and improving the protective effect of the device during spraying.
[0032] Preferably, the auxiliary component 205 includes a limiting frame 205a fixedly installed in the inner cavity of the bearing housing 101, a top spring telescopic rod 205b fixedly installed in the inner wall of the limiting frame 205a, a connecting block 105b fixedly installed in the end of the top spring telescopic rod 205b, and the auxiliary component 205 also includes a top rod 205d fixedly installed in the side wall of the connecting block 105b, and an auxiliary wheel 205e connected to the outer surface of the top rod 205d by a bearing.
[0033] It should be noted that the auxiliary wheel 205e is designed to facilitate smooth pipe rotation, ensure uniform spraying, and improve product quality.
[0034] In use, the inner wall of the pipe is placed against the bottom of the auxiliary wheel 205e, and the pipe is pushed into the bearing shell 101. The motor 102 drives the transmission wheel 204 to rotate via a belt. The two sets of transmission wheels 204 rotate in the same direction, which in turn drives the pipe to rotate. The spray nozzle 202 sprays the anti-corrosion material evenly onto the outer surface of the pipe. The connecting plate 205c works in conjunction with the top spring telescopic rod 205b to accommodate pipes of different thicknesses. During spraying, the hydraulic cylinder 105a retracts, causing the connecting block 105b to move downwards, which in turn causes the movable door 105c to move downwards in conjunction with the slide groove 104 and the slide rail 105d, closing the bearing shell 101.
[0035] In summary, by attaching the inner wall of the pipe to the bottom of the auxiliary wheel 205e and pushing it into the bearing shell 101, the motor 102 drives two sets of co-rotating transmission wheels 204 via a belt, achieving uniform rotation of the pipe. Simultaneously, the spray nozzle 202 evenly sprays the anti-corrosion material onto the outer surface of the pipe. The cooperation between the connecting plate 205c and the top spring telescopic rod 205b adapts to pipes of different thicknesses, ensuring consistent spraying. During spraying, the retraction of the hydraulic cylinder 105a causes the connecting block 105b to move downwards, and the movable door 105c moves downwards through the cooperation of the slide groove 104 and the slide rail 105d, thereby closing the bearing shell 101. The beneficial effect of this cooperation is that it achieves automated and uniform spraying of the anti-corrosion coating on the outer surface of the pipe, improving spraying efficiency and coating quality, while ensuring operational safety and adaptability to pipes of different specifications.
[0036] Example 2
[0037] Reference Figure 3 and Figure 5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an internal spraying assembly 206 for spraying the inner wall of a pipe.
[0038] Specifically, the internal spraying assembly 206 includes a fixing plate 206a fixedly installed in the inner cavity of the bearing housing 101, a cylinder 206b fixedly installed on the side wall of the fixing plate 206a, a clamping block 206c fixedly installed at the end of the cylinder 206b, a connecting wheel 206d adapted to be installed on the side wall of the bearing housing 101, and a limiting box 206e fixedly installed at the end of the connecting wheel 206d.
[0039] Furthermore, the internal spraying assembly 206 also includes a compression spring 206f fixedly installed on the inner wall of the limiting box 206e, a scraper 206g fixedly installed on the end of the compression spring 206f, a connector 206h connected to the inner cavity of the transmission wheel 204 via a bearing, and a spraying pipe 206i connected to the side wall of the connector 206h.
[0040] In use, the inner wall of the pipe is connected to the scraper 206g, the pipe is pushed into the bearing shell 101, the cylinder 206b extends, and pushes the clamping block 206c to clamp and fix the pipe. The compression spring 206f works with the scraper 206g to accommodate pipes of different diameters. The motor 102 drives the connecting wheel 206d to rotate via a belt, and the spray pipe 206i sprays out the anti-corrosion material. The connecting wheel 206d drives the scraper 206g to make a circular motion around the spray pipe 206i as the axis, so as to evenly apply the coating to the inner wall of the pipe. The coating is connected through the connector 206h.
[0041] In summary, by connecting the inner wall of the pipe to the scraper 206g, pushing it into the bearing shell 101, and fixing it with the extension clamp 206c of the cylinder 206b, and cooperating with the compression spring 206f, it is suitable for pipes of different diameters. The motor 102 drives the connecting wheel 206d to rotate through the belt, and the spray pipe 206i sprays out the anti-corrosion material. The connecting wheel 206d drives the scraper 206g to make a circular motion around the spray pipe 206i as the axis, so as to achieve uniform coating of the coating on the inner wall of the pipe. The beneficial effect of this structure is that it can automatically complete the anti-corrosion coating spraying work on the inner wall of the pipe, improve the spraying efficiency and quality, adapt to the needs of pipes of different diameters, and reduce the complexity and labor intensity of manual operation.
