[0001] This utility model relates to the field of transformer oil tank spraying technology, specifically a transformer oil tank anti-corrosion spraying device. Background Technology

[0002] Nowadays, after the transformer tank is manufactured, it needs to be coated with an anti-corrosion coating to slow down the corrosion rate of the transformer tank and extend its service life. At the same time, the coating has certain insulation properties, which can improve the insulation level of the transformer tank surface to a certain extent and prevent safety accidents caused by surface leakage.

[0003] However, when spraying anti-corrosion coatings on the surface of transformer oil tanks, it is mostly done manually with a handheld spray gun. During the manual spraying process, workers need to walk back and forth around the transformer oil tank to ensure that the anti-corrosion coating is evenly sprayed on the surface. After the outer anti-corrosion coating is sprayed on the surface of the transformer oil tank, the transformer oil tank needs to be moved to a lifting device and lifted so that workers can spray the anti-corrosion coating on the bottom of the transformer oil tank. Therefore, the amount of labor required for workers to spray the anti-corrosion coating on the transformer oil tank is quite large. In view of the above situation, technical innovation is carried out on the existing transformer oil tank anti-corrosion spraying device. Summary of the Invention

A lifting plate 19 is fixedly installed at the bottom of the cable of the electric hoist 22. A support plate 13 is placed below the lifting plate 19. A turntable 12 is placed at the bottom of the support plate 13. A worm gear reducer motor 29 is fixedly installed at the bottom of the turntable 12. A dual-axis motor 26 is placed above the electric hoist 22. A set of slide rails 27 is installed on both the left and right sides of the dual-axis motor 26. A screw 33 is rotatably installed inside the slide rail 27. An internally threaded slider 32 is screwed to the outer wall of the screw 33. A pin 28 is fixedly installed on the top of the internally threaded slider 32. The two output ends of the dual-axis motor 26 are respectively connected to the two sets of screws. The screws 33 are connected to each other. The dual-axis motor 26 drives the two sets of screws 33 to rotate. The two sets of screws 33 drive the two sets of internal thread sliders 32 to move inward. The internal thread sliders 32 move the pins 28 inward to separate from the support sleeve 24 and guide rod 25, thereby unlocking the dual-axis motor 26. Two sets of guide rods 25 are evenly fixed on the top of the lifting plate 19. The outer side of the guide rods 25 has a through hole, and the pins 28 are inserted into the through hole. Steel cables 2 are evenly fixed on the bottom of the lifting plate 19. The bottom of the steel cables 2 is fixed with hooks 21. The pins 28 are located above the slide rail 27. The opposite sides of the two sets of screws 33 pass through the opposite sides of the two sets of slide rails 27, and are connected to the dual-axis motor 26. The two output ends of the shaft motor 26 are connected. A set of support sleeves 24 is installed on the opposite sides of each of the two sets of guide rods 25. A pin 28 passes through the insertion hole of the guide rod 25 and is inserted into the support sleeve 24. The support sleeve 24 supports the pin 28, thereby improving the locking stability of the pin 28 on the guide rod 25. A base 1 is placed at the bottom of the turntable 12. An installation groove and an annular convex groove are opened on the top of the base 1. The worm gear reducer motor 29 is fixedly installed in the installation groove. A convex ring 3 is fixedly installed at the bottom of the turntable 12 and rotatably mounted in the annular convex groove. Positioning pins 31 are evenly fixedly installed at the bottom of the support plate 13. The left side of the support plate 13... A set of grooves is provided on both sides of the turntable 12. Positioning holes are evenly provided on the top of the turntable 12. Positioning pins 31 are inserted into the positioning holes. The support plate 13 is placed on the top of the turntable 12 and the positioning pins 31 are inserted into the positioning holes to limit the support plate 13 on the turntable 12. At this time, the transformer oil tank 14 is placed on the support plate 13. The turntable 12 is driven to rotate by the worm gear reducer motor 29. The turntable 12 drives the support plate 13 to rotate through the positioning pins 31, thereby driving the transformer oil tank 14 on the support plate 13 to rotate. The transformer oil tank 14 is placed on the top of the support plate 13. The transformer oil tank 14 is located below the hook 21. The hook 21 corresponds to the lifting lug on the transformer oil tank 14.

[0022] A set of L-plates 11 are fixedly installed on both the left and right sides of the base 1. A top plate 18 is fixedly installed on the top of the two sets of L-plates 11. An electric hoist 22 is fixedly installed on the top of the top plate 18. A clearance groove is opened through the top of the top plate 18. The cable of the electric hoist 22 passes through the clearance groove and connects to the lifting plate 19. A gantry frame 23 is fixedly installed on the top of the top plate 18. The gantry frame 23 is located outside the electric hoist 22. A dual-shaft motor 26 is fixedly installed on the top of the gantry frame 23. Two sets of slide rails 27 are evenly fixedly installed on the top of the gantry frame 23. Two sets of support sleeves 24 are evenly fixedly installed on the top of the top plate 18. Guide holes are evenly opened through the top of the top plate 18. A guide rod 25 is slidably installed in the guide hole. When the transformer oil tank 14 is open... After the anti-corrosion coating is applied, the lifting plate 19 is moved downward by the electric hoist 22, and then the hook 21 is hooked onto the lifting lug of the transformer oil tank 14. The lifting plate 19 is then pulled upward by the electric hoist 22. The lifting plate 19 lifts the transformer oil tank 14 by the steel cable 2 and the hook 21. The guide rod 25 assists the lifting plate 19 to move up and down stably. After the transformer oil tank 14 is lifted, the worker can apply the anti-corrosion coating to the bottom of the transformer oil tank 14. An air pump 15 and a hook 17 are fixedly installed on the right side of the L plate 11 on the right side of the base 1. The air pump 15 is located below the hook 17. A spray gun 16 is suspended on the outside of the hook 17. An air pipe is connected between the air inlet of the spray gun 16 and the air outlet of the air pump 15.

[0023] Working principle: Place the tray 13 on top of the turntable 12 and insert the positioning pin 31 into the positioning hole to limit the tray 13 on the turntable 12. Place the transformer oil tank 14 on the tray 13. Then, the worker removes the spray gun 16 from the hook 17 and drives the spray gun 16 to spray the anti-corrosion coating on the surface of the transformer oil tank 14 through the air pump 15. At this time, the worm gear reducer motor 29 drives the turntable 12 to rotate. The turntable 12 drives the tray 13 to rotate through the positioning pin 31, thereby driving the transformer oil tank 14 on the tray 13 to rotate. This allows the worker to quickly spray the anti-corrosion coating on the surface of the transformer oil tank 14.

[0024] After the anti-corrosion coating is applied to the surface of the transformer tank 14, the dual-shaft motor 26 drives two sets of screws 33 to rotate. These screws 33 then move two sets of internally threaded sliders 32 inwards, raising the internally threaded sliders 32 and causing the pins 28 to move inwards, separating them from the support sleeve 24 and guide rod 25. This unlocks the dual-shaft motor 26. The electric hoist 22 then moves the lifting plate 19 downwards, hooking the hook 21 onto the lifting lug of the transformer tank 14. The electric hoist 22 then pulls the lifting plate 19 upwards, lifting the transformer tank 14 via the steel cable 2 and hook 21. The guide rod 25 assists in the stable up-and-down movement of the lifting plate 19. Once the transformer tank 14 is lifted, workers can apply the anti-corrosion coating to the bottom of the transformer tank 14. After the transformer tank 14 is lifted and the insertion hole on the guide rod 25 is aligned with the pin 28, the dual-axis motor 26 reverses, causing the pin 28 to move outward through the insertion hole of the guide rod 25 and insert into the support sleeve 24, thereby fixing the height of the guide rod 25. The support sleeve 24 supports the pin 28, thereby improving the locking stability of the pin 28 to the guide rod 25. By locking the guide rod 25, the sudden drop of the transformer tank 14 due to the failure of the electric hoist 22 can be prevented. After the anti-corrosion coating is applied to the transformer tank 14 and it is removed from the device, the tray 13 can be moved upward and separated from the turntable 12 by the pull groove on the outside of the tray 13, thereby facilitating the cleaning of the coating on the surface of the tray 13.
