Description

Technical Field

[0001] The invention relates to the technical field of anti-corrosion spraying of metal pipe fittings, and in particular to an anti-corrosion spraying device for metal pipe fittings. Background Art

[0002] Pipe fittings are a general term for components in pipeline systems that play the role of connection, control, direction change, diversion, sealing, support, etc. During the processing of metal pipe fittings, they need to be sprayed with anti-corrosion on the surface to increase their anti-corrosion performance. Therefore, an anti-corrosion spray device is needed.

[0003] During use of the existing anti-corrosion spraying device for metal pipes, after the metal pipe is fixed, the rotating mechanism drives it to rotate, and the outer nozzle sprays it. However, there are many types of metal pipes, and their shapes are different. Some are straight tubular structures, and some are irregular in shape. For irregular metal pipes, conventional spraying methods cannot achieve all-round spraying of the outer surface of the metal pipes. During the spraying process, the bent parts on the irregular metal pipes are easily blocked by the upper and lower parts of the metal pipes themselves, resulting in the sprayed anti-corrosion paint being unable to smoothly adhere to the outer wall of the bent parts, thereby reducing the spraying effect of the metal pipes. Summary of the invention

However, there are many types of metal pipe fittings, and their shapes are different. Some are straight tubular structures, and some are irregular in shape. For irregular metal pipe fittings, conventional spraying methods cannot achieve all-round spraying of the outer surface of the metal pipe fittings. During the spraying process, the bent parts on the irregular metal pipe fittings are easily blocked by the upper and lower parts of the metal pipe fittings themselves, resulting in the sprayed anti-corrosion paint being unable to smoothly adhere to the outer wall of the bent parts.

At the same time, the quick clamping of the metal pipe fittings improves the overall efficiency of the anti-corrosion spraying process.

[0013] In a preferred embodiment, an extension column is fixedly connected to the top of the rotating shaft, and hydraulic cylinders three are distributed in a ring on the outer wall of the extension column.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] The present invention discloses an anti-corrosion spray device for metal pipe fittings, which is mainly applied to the existing anti-corrosion spray device for metal pipe fittings. During use, after the metal pipe fitting is fixed, the rotating mechanism drives it to rotate, and the outer nozzle sprays it. However, there are many types of metal pipe fittings, and their shapes are different. Some are straight tubular structures, and some are irregular in shape. For irregular metal pipe fittings, conventional spraying methods cannot achieve all-round spraying of the outer surface of the metal pipe fittings. During the spraying process, the bent parts on the irregular metal pipe fittings are easily blocked by the upper and lower parts of the metal pipe fittings themselves, resulting in the scene where the sprayed anti-corrosion paint cannot be smoothly adhered to the outer wall of the bent part.

[0033] Reference Figure 1-Figure 10 , an anti-corrosion spraying device for metal pipe fittings, comprising a base 1, a support frame 3 is fixedly connected to the top of the base 1, and a directional spraying assembly 7 is arranged on the top of the support frame 3, the directional spraying assembly 7 comprises an outer ring plate 701, and the outer ring plate 701 is fixedly connected to the top of the support frame 3, and the inner wall of the outer ring plate 701 is provided with mounting grooves 708 at equal distances, and a positioning plate 703 is fixedly connected to the inside of each mounting groove 708, and two limiting sliding grooves 709 are provided on each positioning plate 703, and two limiting sliding blocks 714 are slidably connected to the inside of each limiting sliding groove 709, and a connecting block 713 is fixedly connected to the side of each limiting sliding block 714 facing the center line of the positioning plate 703, and the same positioning plate 70 is located The outer walls of the multiple connecting blocks 713 on 3 are fixedly connected to the same spray pipe 702, and the outer wall of the spray pipe 702 facing obliquely upward is provided with spray holes at equal distances, and the interior of each spray hole is fixedly connected to a spray nozzle 705, and the outer wall of the positioning plate 703 away from the spray pipe 702 is fixedly connected to two back blocks 706, and the two back blocks 706 are fixedly connected to the side of the spray pipe 702 The hydraulic cylinder 1 707 is fixedly connected, and the output end of the hydraulic cylinder 1 707 is fixedly connected to a docking block 711, and the side of the docking block 711 facing the spray pipe 702 is fixedly connected to an electromagnet 710, and the outer wall of the spray pipe 702 facing the electromagnet 710 is fixedly connected to an iron block 712, and one of the electromagnets 710 is in contact with the iron block 712.

[0034] In a specific application scenario, when anti-corrosion spraying is performed on the outer surface of a metal pipe fitting, it is placed on the quick clamping assembly 12. If it is a regular shape, the cylinder 14 drives the metal pipe fitting to rise and fall, and each spray nozzle 705 sprays the anti-corrosion paint to quickly complete the spraying operation. If it is an irregular shape, the electromagnet 710 is energized, and the uppermost electromagnet 710 is adsorbed with the iron block 712. The hydraulic cylinder 707 at this position is adjusted to drive the spray pipe 702 to move toward the center position of the outer ring plate 701, and the spray pipe 702 is bent. At the same time, When the spray tube 702 moves outward, the spray tube 702 below slides toward the top of the positioning plate 703 under the action of the limit slider 714, so that the electromagnet 710 located below contacts and adsorbs the second iron block 712, and then adjusts the hydraulic cylinder 707 below to drive the spray tube 702 to move again. Under the double adjustment, the spray tube 702 presents an inverted "3" bending state, so that each spray nozzle 705 is tilted, and the anti-corrosion paint sprayed by the spray nozzle 705 directly faces the various bending parts of the metal pipe fittings, thereby improving the uniformity of the anti-corrosion paint spraying on the outside of the metal pipe fittings.

[0035] It should be noted that when the upper spray tube 702 is passively bent and extended outward, the spray tube 702 located below moves toward the positioning plate 703 to fill the lower spray nozzle 705. When the metal pipe moves from bottom to top, the spray nozzle 705 located below can achieve spraying in regular shapes to ensure that the metal pipe is completely anti-corrosion sprayed.

[0036] Reference Figure 1-Figure 6 In a preferred embodiment, the inner wall of the support frame 3 is annularly distributed with connecting frames 11, and the tops of multiple connecting frames 11 are fixedly connected to the same feed pipe 704, and the outer wall of the feed pipe 704 facing upward is annularly opened with feed holes, and the spray pipe 702 is inserted into the corresponding feed holes, the outer wall of the support frame 3 is fixedly connected with a pump frame 5, and the top of the pump frame 5 is fixedly connected with a feed pump 6, the feed end of the feed pump 6 is connected to the inside of the feed pipe 704 through a pipeline, and the feed end of the feed pump 6 is fixedly connected to the extraction pipe 4.

[0037] Reference Figure 1 , Figure 2 and Figure 7 In a preferred embodiment, a cylinder 14 is fixedly connected to the top center of the base 1, and a motor frame 9 is fixedly connected to the top of the cylinder 14. A quick clamping assembly 12 is provided above the motor frame 9, and the quick clamping assembly 12 includes a rotating shaft 1202.

[0038] In the present invention, the motor frame 9 is fixedly connected to the inside of the driving motor 2 1201, and the rotating shaft 1202 is connected to the output shaft of the driving motor 2 1201 through a coupling, the outer wall of the rotating shaft 1202 is fixedly connected to the fixing ring 1209, the outer wall of the rotating shaft 1202 near the top is equidistantly connected to the inner pressure arc plate 1203 through a hinge, the outer wall of the inner pressure arc plate 1203 facing the fixing ring 1209 is fixedly connected to the extrusion spring rod 1204, one end of the extrusion spring rod 1204 is fixedly connected to the outer wall of the fixing ring 1209, the top of the rotating shaft 1202 is fixedly connected to the extension column 1207, and the outer wall of the extension column 1207 is annularly distributed with hydraulic cylinders 3 1208, the output end of each hydraulic cylinder 3 1208 is fixedly connected to the inner support plate 1206, and the outer wall of each inner support plate 1206 away from the extension column 1207 is provided with friction teeth 1205.

[0039] Specifically, before anti-corrosion spraying of metal pipe fittings, the open end of the metal pipe fittings is directly placed on the quick clamping assembly 12. As the metal pipe fittings move downward, the inner pressure arc plate 1203 is squeezed against the inner wall of the metal pipe fittings, and the extrusion spring rod 1204 is passively compressed to complete a clamping operation. Then, the hydraulic pressure is adjusted to drive each inner support plate 1206 to move toward the inner wall of the metal pipe fittings. The inner support plate 1206 is squeezed against the inner wall of the metal pipe fittings to complete a secondary clamping operation, thereby improving the firmness of the metal pipe fittings clamping. At the same time, the quick clamping of the metal pipe fittings improves the overall efficiency of the anti-corrosion spraying process.

[0040] Reference Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10In a preferred embodiment, the inner wall of the support frame 3 is fixedly connected to two outer plates 17, and the same dust cleaning component 8 is provided on the opposite side of the two outer plates 17. The dust cleaning component 8 includes an outer tube 801, which is fixedly connected to the outer walls of the two outer plates 17. Two lifting slots are provided on the top of the outer tube 801, and the insides of the two lifting slots are slidably connected with lifting slide bars 802. The opposite side of the two lifting slide bars 802 is fixedly connected to the same dust collection ring tube 805, and the outer wall of the dust collection ring tube 805 is equidistantly provided with dust collection holes 804. The outer walls of the outer tube 801 located at the two lifting slots are fixedly connected to side frames 807, and the top of the side frames 807 is fixedly connected to hydraulic cylinder 2 803. The output end of the second hydraulic cylinder 803 is fixedly connected to the top of the lifting slide bar 802, and the top of one of the outer plates 17 is fixedly connected to an adsorption pump 808, and the adsorption end of the adsorption pump 808 is fixedly connected to a negative pressure adsorption tube 806, and one end of the negative pressure adsorption tube 806 is inserted into the interior of the dust collection ring tube 805. The inner wall of the sliding ring frame 18 is fixedly connected to a rotating ring frame 811, and the top of the rotating ring frame 811 is fixedly connected to an ejector rod 809 at an equal distance, and the outer wall of each ejector rod 809 is evenly spaced with bristles 810, and the outer wall of the ejector rod 809 located between each two groups of bristles 810 is fixedly connected to an elastic rod 812, and the outer wall of each elastic rod 812 away from the ejector rod 809 is fixedly connected to an impact ball 813.

[0041] Specifically, after the metal pipe is clamped, the cylinder 14 drives it to enter the outer tube 801 and starts the drive motor 2. The drive motor 2 drives the rotating ring frame 811 to rotate, thereby driving the bristles 810 on the ejection rod 809 to clean the outer wall of the metal pipe. At the same time, the drive motor 2 1201 is started, and the drive motor 2 1201 drives the metal pipe to rotate in the opposite direction of the rotation direction of the bristles 810. The bristles 810 quickly contact the metal pipe, thereby improving the dust cleaning effect on the outside of the metal pipe.

[0042] It should be noted that during the cleaning process of the bristles 810, the elastic rod 812 in a rotating state drives the impact ball 813 to slightly impact the outer wall of the metal pipe, causing the metal pipe to be in a state of vibration, thereby accelerating the shedding of dust on the outside thereof. At the same time, the adsorption pump 808 is started, and the hydraulic cylinder 803 is adjusted to drive the dust collection ring tube 805 to move up and down. The adsorption pump 808 quickly collects the fallen dust through the various dust collection holes 804 on the dust collection ring tube 805 to prevent the dust from re-attaching to the outer wall of the metal pipe during the rising process of the metal pipe.

[0043] Specifically, the dust collecting ring tube 805 moves up and down to collect dust attached to each bristle 810 at the same time, so as to prevent the dust attached to the bristles 810 from causing secondary pollution to the outer side of the metal pipe.

[0044] Reference Figure 1 , Figure 8 and Fig. 9 In a preferred embodiment, the top of the base 1 is fixedly connected to a driving motor 2, and the output shaft of the driving motor 2 is fixedly connected to a driving shaft 10 through a coupling, the outer side of the driving shaft 10 is fixedly connected to a driving gear disc 13, the bottom of the outer tube 801 is fixedly connected to an annular guide rail 15, the inside of the annular guide rail 15 is slidably connected to a sliding ring frame 18, the outer side wall of the sliding ring frame 18 is fixedly connected to a driven gear disc 16, and the driving gear disc 13 and the driven gear disc 16 are meshed.

[0045] Working principle: When in use, place the open end of the metal pipe directly into the quick clamping assembly 12. As the metal pipe moves downward, the inner pressure arc plate 1203 is squeezed against the inner wall of the metal pipe, and the squeezing spring rod 1204 is passively compressed to complete one clamping. Then, the hydraulic pressure 3 is adjusted to drive each inner support plate 1206 to move toward the inner wall of the metal pipe. The inner support plate 1206 is squeezed against the inner wall of the metal pipe to complete the second clamping. After the clamping is completed, the cylinder 14 drives it to enter the inner part of the outer tube 801, and the drive motor 12 is started, and the drive motor 12 drives the rotation The ring frame 811 rotates, thereby driving the bristles 810 on the ejection rod 809 to clean the outer wall of the metal pipe. At the same time, the drive motor 1201 is started, and the drive motor 1201 drives the metal pipe to rotate in the opposite direction of the rotation direction of the bristles 810. The bristles 810 quickly contact the metal pipe to complete the dust cleaning operation on the outer side of the metal pipe. After the dust cleaning is completed, the cylinder 14 drives the metal pipe to gradually rise, and the drive motor 1201 drives the metal pipe to rotate, and the feed pump 6 is started. The feed pump 6 delivers the anti-corrosion paint to each spray nozzle 705, and the anti-corrosion paint is sprayed on the outer wall of the metal pipe. The nozzle 705 sprays the outer wall of the metal pipe with anti-corrosion. If the metal pipe is of regular shape, the cylinder 14 drives it to pass through each spray nozzle 705, and the operation is ended. If the metal pipe is of irregular shape, the electromagnet 710 is energized, and the uppermost electromagnet 710 is attracted to the iron block 712, and the hydraulic cylinder 707 at this position is adjusted to drive the spray pipe 702 to move toward the center position of the outer ring plate 701, and the spray pipe 702 is bent. At the same time, the spray pipe 702 moves toward the outside, and the lower spray pipe 702 moves to the outside under the action of the limit slider 714. The cylinder 14 drives the metal pipe to move upward, and then drives it downward to the top of the outer tube 801, and then moves back and forth twice to ensure that the outer wall of the irregularly shaped metal pipe is completely sprayed.
