Description

Technical Field

[0001] This invention relates to the field of power fittings technology, and in particular to a surface treatment device for corrosion-resistant power fittings. Background Technology

[0002] Power fittings are a general term for metal accessories used in power transmission and distribution systems to connect, fix, protect, and splice overhead conductors, insulators, and tower crossarms. They are indispensable basic components in the construction and operation of power lines. Although they do not directly conduct current, they play a crucial supporting role in the safe, reliable, and efficient operation of the entire system. Power fittings can be categorized into suspension clamps, tension clamps, UT clamps, connecting fittings, splicing fittings, protective fittings, equipment clamps, T-clamps, busbar fittings, and guy wire fittings. Because they are frequently exposed to air and subject to rain erosion, their surfaces often rust. Therefore, surface treatment is necessary, typically achieved through painting, to extend their service life.

[0003] When painting right-angle brackets, they need to be clamped and fixed by a suspension system. There are some holes on the right-angle brackets for connection. Existing processing equipment can only paint the outer surface and ignores the inner wall of the hole, which is also the most susceptible to corrosion. Therefore, when the bolt is inserted into the hole, long-term exposure to rainwater will accelerate the surface corrosion, thus creating a safety hazard.

[0004] This invention provides a surface treatment device for corrosion-resistant electrical fittings to solve the problems existing in the prior art. Summary of the Invention

Detailed Implementation

[0026] The prior art discloses a surface treatment system for power fittings, application number 202011215601.6, which includes a base plate, an actuating mechanism, a spraying mechanism and a fixing mechanism. The actuating mechanism is installed at the upper end of the base plate, the spraying mechanism is installed at the upper end of the actuating mechanism, and the fixing mechanisms are installed on the left and right sides of the spraying mechanism. The fixing mechanisms are installed on the base plate. In practice, the tension cylinder is activated to move the spraying mechanism upwards until all the vertical top plates contact the bottom of the clamp. At this point, the distance from all the spray plugs to the bottom of the clamp is equal. The pressure pump is activated, and the paint in the paint box is sprayed through the spray plugs to the bottom of the clamp. When the bottom of the clamp is evenly sprayed, the electric slider is activated to move the rack upwards, which in turn drives the incomplete gear to rotate, thus rotating the cover plate. The lower pressure block presses down on the spray plugs, and the outer wall of the spray column aligns with the annular cover groove. The electric slider is closed, and the spraying stops. The tension cylinder is activated to move the spraying mechanism downwards, causing all the vertical top plates to disengage from the bottom of the clamp. The tension cylinder is closed, and the rotation motor is activated to finally control the vertical top plates to be directly in front of the spray plugs. The tension cylinder is activated again to move the spraying mechanism upwards until all the vertical top plates contact the bottom of the clamp. The electric slider is activated, and under the combined action of the rack and the incomplete gear, the cover plate is rotated. The pressure pump is activated for a second spraying, ensuring that the bottom of the clamp is fully and comprehensively sprayed. The positioning cylinder is activated, causing the moving plate to move to the left. Under the combined action of the positioning and moving plates, the position of the clamp is fixed. The tension cylinder is activated, causing the spraying mechanism to move upward until all the vertical top plates contact the bottom of the clamp. The pressure pump is activated to perform the initial spraying on the bottom of the clamp. The electric slider is activated, and under the combined action of the rack and pinion, the cover plate rotates, which stops the spraying. Under the combined action of the tension cylinder and the rotating motor, the vertical top plates contact the front half of the bottom of the clamp. The electric slider is activated to finally control the rotation of the cover plate for a second all-around spraying.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figures 1-8As shown, this embodiment provides a surface treatment device for corrosion-resistant power fittings, including a suspension 1. A fixed plate 2 is fixedly connected to the top of the suspension 1. A movable block 3 is provided below the fixed plate 2. The movable block 3 can move in the vertical direction. A clamping mechanism is provided below the movable block 3. A driving component is installed inside the movable block 3. The driving component is used to control the rotation of the clamping mechanism. The clamping mechanism is used to clamp a right-angle hanging plate 5. An adjustment device is provided on one side of the suspension 1. A spraying rod 6 is installed on the adjustment device. The adjustment device can drive the spraying rod 6 to move. A first spray hole 32 is opened at the end of the spraying rod 6. The first spray hole 32 is used to spray the outer surface of the right-angle hanging plate 5. A plurality of second spray holes 40 are opened circumferentially on the side wall of the spraying rod 6. After the spraying rod 6 is inserted into the circular hole, the inner wall of the circular hole is sprayed through the second spray holes 40.

[0030] This invention, through the combination of components such as suspension 1, moving block 3, clamping mechanism, adjusting device and spraying rod 6, realizes the spraying of the outer surface of right-angle hanging plate 5 and the spraying of the inner wall of its circular hole, providing an effective device basis for the anti-corrosion treatment of power fittings, and can meet the spraying needs of different parts of power fittings, improving the comprehensiveness and uniformity of spraying.

[0031] Further refining the scheme, the clamping mechanism includes a strip block 17, which is connected to the driving component. A frame 4 is fixedly connected to the bottom surface of the strip block 17. An extrusion block 19 is installed inside the frame 4. A third hydraulic cylinder 18 is fixedly installed inside the strip block 17. The output end of the third hydraulic cylinder 18 extends into the frame 4 and is fixedly connected to the extrusion block 19. Sliding blocks 20 are slidably connected to both ends of the extrusion block 19. The sliding blocks 20 are slidably connected to the frame 4. A clamping plate 21 is fixedly connected to the bottom surface of the sliding block 20. The top of the clamping plate 21 contacts the bottom surface of the frame 4. The two clamping plates 21 are used to clamp the right-angle hanging plate 5. By pushing the extrusion block 19 with the third hydraulic cylinder 18, the sliding blocks 20 and clamping plates 21 move, thereby clamping the right-angle hanging plate 5. This clamping method has a simple structure, is easy to operate, and can stably clamp the right-angle hanging plate 5, ensuring that the position of the right-angle hanging plate 5 is fixed during the spraying process, thus improving the accuracy and quality of the spraying.

[0032] Further refining the design, the driving component includes a first motor 16 installed within the movable block 3. A small gear 11 is fixedly connected to the output end of the first motor 16, and the small gear 11 meshes with a large gear 12. A connecting shaft is fixedly connected to the center of the large gear 12, and the bottom of the connecting shaft is fixedly connected to the top surface of the strip block 17. The first motor 16 drives the small gear 11 to rotate, and the small gear 11 meshes with the large gear 12, thereby driving the connecting shaft and the strip block 17 to rotate, thus realizing the rotation of the clamping mechanism. This driving method can precisely control the rotation angle and speed of the clamping mechanism, ensuring that the right-angle hanging plate 5 receives coating evenly during the spraying process, improving the spraying effect.

[0033] Further refining the design, a first hydraulic cylinder 10 is fixedly connected to the top surface of the fixed plate 2. The output end of the first hydraulic cylinder 10 is fixedly connected to the top surface of the moving block 3, and the first hydraulic cylinder 10 drives the moving block 3 to move vertically. By fixing the output end of the first hydraulic cylinder 10 to the top surface of the moving block 3, the first hydraulic cylinder 10 can drive the moving block 3 to move vertically, thereby adjusting the height of the clamping mechanism and the right-angle hanging plate 5, enabling it to adapt to different spraying height requirements and improving the versatility and flexibility of the device.

[0034] Further refining the design, a flexible hose is connected to the end of the spray bar 6 furthest from the first spray hole 32, and a storage tank 9 is connected to the end of the flexible hose furthest from the spray bar 6. Connecting the spray bar 6 and the storage tank 9 via the flexible hose allows paint to be smoothly transported from the storage tank 9 to the spray bar 6, providing a stable paint supply for the spraying process and ensuring the continuity of the spraying work.

[0035] Further refining the design, the adjustment device includes a fixed base 8, with a lifting rod 7 slidably connected to the top surface of the fixed base 8. A support plate 14 is fixedly connected to the top of the lifting rod 7. The lifting rod 7 can drive the support plate 14 to move vertically. A second hydraulic cylinder 13 is fixedly installed on the support plate 14, and a connecting plate 15 is fixedly connected to the output end of the second hydraulic cylinder 13. The spraying rod 6 is fixedly installed on the connecting plate 15. By moving the support plate 14 vertically with the lifting rod 7, and by moving the connecting plate 15 and the spraying rod 6 horizontally with the second hydraulic cylinder 13, the position of the spraying rod 6 in three-dimensional space is adjusted. This allows the spraying rod 6 to be accurately moved to different parts of the right-angle mounting plate 5 for spraying, improving the accuracy and efficiency of spraying.

[0036] Specifically, the existing hydraulic lifting structure (not shown in the figure) is installed inside the lifting rod 7, so that the lifting rod 7 can drive the support plate 14 to move in the vertical direction; the existing screw slider structure (not shown in the figure) is installed inside the fixed seat 8, so that the lifting rod 7 can slide, thereby controlling the spraying rod 6 to move in multiple directions.

[0037] Further refining the design, the spraying rod 6 is equipped with several flow channels 31, which are respectively connected to the first spray hole 32 and the second spray hole 40. A ring 22 is fixedly installed inside the spraying rod 6, and several U-shaped blocks 23 are circumferentially slidably connected to the ring 22. The several U-shaped blocks 23 are arranged one-to-one with the several second spray holes 40. An extrusion mechanism is installed inside the spraying rod 6, which is drivenly connected to the U-shaped blocks 23. The extrusion mechanism is also drivenly connected to a sealing rod 34. When the U-shaped blocks 23 block the second spray hole 40, the paint flows to the first spray hole 32 through the middle notch of the U-shaped blocks 23 and the flow channels 31. When the extrusion mechanism reverses its transmission, the sealing rod 34 blocks the first spray hole 32, the U-shaped blocks 23 contract, and the second spray hole 40 is opened, and the paint is sprayed out through the second spray hole 40. The extrusion mechanism, through its transmission connection with the U-shaped block 23 and the sealing rod 34, enables the switching between the first spray hole 32 and the second spray hole 40. When the outer surface of the right-angle hanging plate 5 needs to be sprayed, the U-shaped block 23 blocks the second spray hole 40, and the paint is sprayed out from the first spray hole 32. When the inner wall of the round hole needs to be sprayed, the sealing rod 34 blocks the first spray hole 32, the U-shaped block 23 retracts and opens the second spray hole 40, and the paint is sprayed out from the second spray hole 40. This design allows for flexible switching of the spray holes according to different spraying needs, improving the targeting and effectiveness of the spraying.

[0038] Further refining the scheme, a disc 24 is rotatably connected to the inner ring 22. Several inclined grooves 25 are opened circumferentially on the disc 24. A cylinder 26 is fixedly connected to the U-shaped block 23. The cylinder 26 extends into the inclined groove 25 and is slidably connected to the inclined groove 25. A sleeve 27 is fixedly connected to the center of the disc 24. A circumferential groove 29 is opened on the sleeve 27. A protrusion 30 is slidably connected in the circumferential groove 29. An extrusion rod 28 is slidably connected in the sleeve 27. The protrusion 30 is fixedly connected to the extrusion rod 28. The extrusion rod 28 is drivenly connected to the extrusion mechanism. The movement control of the U-shaped block 23 and the extrusion rod 28 is achieved by sliding the inclined groove 25 on the disc 24 to the cylinder 26 on the U-shaped block 23, and sliding the circumferential groove 29 on the sleeve 27 to the protrusion 30. When the extrusion rod 28 moves, it drives the sleeve 27 and the disc 24 to rotate, thereby causing the U-shaped block 23 to move under the action of the inclined groove 25, realizing the switching of the spray hole. This ingenious structural design can achieve precise switching of the spray hole and improve the reliability and stability of the device.

[0039] Further refining the design, the extrusion mechanism includes a second motor 36 fixedly connected to the inner wall of the spray rod 6. An eccentric block 37 is fixedly connected to the output end of the second motor 36. The extrusion rod 28 contacts the side wall of the eccentric block 37, and the sealing rod 34 contacts the eccentric block 37. The second motor 36 drives the eccentric block 37 to rotate, causing it to contact the extrusion rod 28 and the sealing rod 34, thus realizing the movement of the extrusion rod 28 and the sealing rod 34. When the eccentric block 37 rotates, it pushes the extrusion rod 28 and the sealing rod 34 to move, achieving the switching of spray nozzles. This driving method has a simple structure, is easy to control, and can accurately realize the switching action of the spray nozzles.

[0040] Further refining the design, baffles 39 are fixedly connected to the ends of the sealing rod 34 and the extrusion rod 28 near the eccentric block 37, respectively. The baffles 39 contact the eccentric block 37. The sealing rod 34 and the extrusion rod 28 are respectively slidably connected through and to a limiting plate 33. The limiting plate 33 is fixedly connected to the inner wall of the spraying rod 6. A first spring 35 is sleeved on the outer side of the sealing rod 34, and a second spring 38 is sleeved on the outer side of the extrusion rod 28. The first spring 35 and the second spring 38 are respectively located between the baffle 39 and the limiting plate 33. Through the contact between the baffle 39 and the eccentric block 37, and the limiting effect of the limiting plate 33 on the extrusion rod 28 and the sealing rod 34, the extrusion rod 28 and the sealing rod 34 are prevented from shifting during movement. At the same time, the first spring 35 and the second spring 38 can provide a restoring force for the extrusion rod 28 and the sealing rod 34, ensuring that they can accurately return to their initial positions during the rotation of the eccentric block 37, thus improving the reliability and stability of the device.

[0041] Working principle:

[0042] First, the third hydraulic cylinder 18 is activated, and its output end pushes the extrusion block 19 to move within the frame 4. The extrusion block 19 presses against the two sliding blocks 20, causing them to move in opposite directions, thereby moving the clamping plate 21. At this time, the two clamping plates 21 open, and the right-angle hanging plate 5 is placed between them. The third hydraulic cylinder 18 drives the extrusion block 19 to move in opposite directions until the right-angle hanging plate 5 is stably clamped. The lifting rod 7 is moved by the fixed seat 8, and the lifting rod 7 adjusts the height of the support plate 14. The second hydraulic cylinder 13 moves the spraying rod 6, thereby achieving multi-directional movement of the spraying rod 6. The paint is transported from the storage tank 9 through the hose to the spraying rod 6 and sprayed out through the first spray hole 32 connected to the flow channel 31 to spray the outer surface of the right-angle hanging plate 5. When it is necessary to spray the inner wall of the round hole of the right-angle hanging plate 5, the second motor 36 rotates, driving the eccentric block 37 to rotate. The eccentric block 37 presses against the sealing rod 34 to block the first spray hole 32, and at the same time, the second spring 38... The pressure rod 28 is reset under pressure, which drives the sleeve 27 to rotate in the opposite direction. The sleeve 27 drives the disc 24 to rotate in the opposite direction, which causes each U-shaped block 23 to retract and reset. At this time, the second spray hole 40 opens, and the spraying rod 6 is inserted into the round hole of the right-angle hanging plate 5 to spray the inner wall of the round hole. The height of the right-angle hanging plate 5 can be adjusted by the first hydraulic cylinder 10. The first motor 16 drives the small gear 11 to rotate, and the small gear 11 drives the large gear 12 to rotate, which can adjust the angle of the right-angle hanging plate 5, so as to facilitate spraying on all surfaces and to facilitate the spraying rod 6 to be inserted into the round holes in different directions, thus improving the spraying efficiency. After the outer surface of the right-angle hanging plate 5 and the inner wall of the round hole are sprayed, all components stop working. The first hydraulic cylinder 10 drives the moving block 3 to rise, so that the clamping mechanism and the right-angle hanging plate 5 leave the spraying area. The third hydraulic cylinder 18 is activated, so that the clamping plate 21 releases the right-angle hanging plate 5 and removes the sprayed right-angle hanging plate 5. Then, the device can perform the next spraying operation.

[0043] Throughout the entire process, the various components cooperate with each other, and through precise control and adjustment, a comprehensive and uniform anti-corrosion spraying treatment is achieved on the right-angle mounting plate 5, which improves the anti-corrosion performance and service life of the power fittings.
