Description

Technical Field

[0001] This utility model relates to the technical field of seamless steel pipe processing equipment, and in particular to a processing equipment for corrosion-resistant seamless steel pipes. Background Technology

[0002] Seamless steel pipes are made by piercing a single round steel bar, and have no weld seams on their surface. They are mainly used as drilling pipes for oil and geological processes, cracking pipes for petrochemicals, boiler tubes, bearing tubes, and high-precision structural steel pipes for automobiles, tractors, and aviation.

[0003] After seamless steel pipes are manufactured, to improve their corrosion resistance, they need to be derusted and degreased, and then coated with anti-corrosion paint on both the outer and inner surfaces. Because seamless steel pipes are long and heavy, conventional anti-corrosion treatments are not suitable, and manual application is usually required. The small internal space of seamless steel pipes makes it difficult for workers to inspect the coating application process, making it challenging to ensure even coverage. Utility Model Content

[0004] The purpose of this invention is to provide a processing device for corrosion-resistant seamless steel pipes, which can automatically apply anti-corrosion coating to the inner wall of seamless steel pipes, ensuring uniform distribution of the anti-corrosion coating and guaranteeing coating quality.

[0005] To achieve the above objectives, a processing device for corrosion-resistant seamless steel pipes is provided, comprising a steel pipe body, a first clamping mechanism installed on the outer side of the steel pipe body, and the steel pipe body being clamped by the first clamping mechanism, a spraying mechanism provided at one end of the steel pipe body, and the end of the steel pipe body extending into and being clamped by the spraying mechanism, a drive motor fixedly connected to the end of the spraying mechanism away from the first clamping mechanism, a support mechanism provided at the bottom of the first clamping mechanism and the spraying mechanism, and both the first clamping mechanism and the spraying mechanism being mounted on the support mechanism, a support leg fixedly connected to the bottom of the support mechanism, a collection trough fixedly connected to one side of the support leg, and the collection trough being located on the side of the first clamping mechanism away from the spraying mechanism, a paint pump fixedly connected to the surface of the support leg, and the input end of the paint pump communicating with the bottom of the collection trough, and an infusion hose fixedly connected to the output end of the paint pump, and the end of the infusion hose away from the paint pump being mounted on the spraying mechanism. The equipment can automatically apply anti-corrosion coating to the inner wall of seamless steel pipes, ensuring uniform distribution of the anti-corrosion coating and guaranteeing coating quality.

[0006] According to the aforementioned equipment for processing corrosion-resistant seamless steel pipes, the spraying mechanism comprises a housing, a second clamping mechanism, a drive disc, a connecting cover, support gears, and a spray head. The lower middle part of the housing is rotatably connected to the support mechanism. The support gears and the drive disc are rotatably connected within the housing, with one end of the drive disc penetrating the housing. Multiple support gears are provided and equidistantly surround the outside of the drive disc, meshing with it. The second clamping mechanism is fixedly connected to one end of the housing and to the side of the drive disc facing the first clamping mechanism. The connecting cover is fixedly connected to the end of the housing away from the second clamping mechanism. The spray head is installed at the middle of the end of the drive disc penetrating the housing, with its interface penetrating the middle of the drive disc and the connecting cover sequentially. The interface of the spray head is fixedly connected to the connecting cover, and its outer side is rotatably connected to the drive disc. The interface of the spray head is fixedly connected to an infusion tubing. The drive motor is fixedly connected to the surface of the connecting cover, with its output end penetrating the connecting cover and rotatably connected to it. The output end of the drive motor is fixedly connected to any one of the shafts of the multiple support gears. The nozzle sprays anti-corrosion coating onto the inner wall of the seamless steel pipe. The drive motor and the support gear work together to make the drive disc drive the second clamping mechanism to rotate, causing the steel pipe body held by the second clamping mechanism to rotate, so that the anti-corrosion liquid is distributed to all parts of the inner wall of the steel pipe body.

[0007] According to the aforementioned processing equipment for corrosion-resistant seamless steel pipes, the support mechanism comprises a mounting frame, a support frame, and a hydraulic rod. The support legs are fixedly connected to the bottom of the support frame, and the mounting frame and hydraulic rod are fixedly connected to the upper end of the support frame, with the mounting frame and hydraulic rod located on opposite sides of the support frame. The bottom of the first clamping mechanism is rotatably connected to the upper middle part of the mounting frame, and the upper end of the hydraulic rod is rotatably connected to the lower middle part of the spraying mechanism. The hydraulic rod pushes the spraying mechanism upwards, causing one end of the steel pipe body to rise, thereby allowing excess anti-corrosion coating in the steel pipe body to flow out through the lower end of the steel pipe body into a collection tank for recycling.

[0008] According to the aforementioned processing equipment for corrosion-resistant seamless steel pipes, a spring connector is rotatably connected to the end of the spraying mechanism away from the first clamping mechanism, and the spring connector is rotatably connected to the connecting cover. A support plate is rotatably connected to the end of the spring connector away from the spraying mechanism, and the bottom of the support plate is fixedly connected to the support mechanism. After the spring connector causes the hydraulic rod to lower and reset the spraying mechanism, it pulls the spraying mechanism vertically, facilitating the subsequent insertion of one end of the seamless steel pipe into the coating mechanism.

[0009] According to the aforementioned equipment for processing corrosion-resistant seamless steel pipes, the first clamping mechanism comprises a top plate, an upper clamping frame, and a lower clamping frame. The bottom of the lower clamping frame is rotatably connected to the mounting frame. Two guide columns are symmetrically fixedly connected to the upper end of the lower clamping frame. The top plate is fixedly connected to the upper ends of the two guide columns. The upper clamping frame is positioned between the top plate and the lower clamping frame, with the guide columns penetrating the upper clamping frame and slidably connected to it. The upper and lower clamping frames are symmetrically arranged. An adjusting bolt is provided at the upper end of the top plate, with the lower end of the adjusting bolt penetrating the top plate and threadedly connected to it. The lower end of the adjusting bolt is rotatably connected to the upper end of the upper clamping frame. The second clamping mechanism has the same structure as the first clamping mechanism. The adjusting bolt pushes the upper clamping frame downward, cooperating with the lower clamping frame to clamp the steel pipe body, preventing the steel pipe body from falling out of the device during the coating process.

[0010] According to the processing equipment for corrosion-resistant seamless steel pipes, the lower clamping frame and the upper clamping frame have arc surfaces in their middle portions. A plurality of support rollers are rotatably connected to the arc surfaces of the lower and upper clamping frames in the first clamping mechanism. The arc surfaces ensure full contact between the first and second clamping mechanisms and the surface of the steel pipe body. The support rollers reduce wear between the surface of the steel pipe body and the first clamping mechanism when the steel pipe body rotates.

[0011] According to the aforementioned equipment for processing corrosion-resistant seamless steel pipes, the lower clamping frame in the second clamping mechanism is fixedly connected to the drive disc, and the nozzle is located between the lower and upper clamping frames in the second clamping mechanism, with the nozzle facing upwards. When the drive disc rotates, it drives the steel pipe body to rotate through the second clamping mechanism. The upward-facing nozzle causes the anti-corrosion coating to flow from the inner wall of the higher end of the steel pipe body to the lower end.

[0012] According to the aforementioned equipment for processing corrosion-resistant seamless steel pipes, the surface of the support roller is coated with an anti-slip coating. The anti-slip coating increases the friction on the support roller surface, preventing the steel pipe body from sliding within the first and second clamping mechanisms after the device is tilted, thus preventing the anti-corrosion coating sprayed from the nozzle from being ejected from the gap between the steel pipe body and the drive disc.

[0013] The above solution has the following advantages: the steel pipe body is clamped by the first clamping mechanism and the second clamping mechanism, the hydraulic rod cooperates with the spraying mechanism to tilt the steel pipe body, the nozzle sprays anti-corrosion coating onto the inner wall of the steel pipe body, the drive motor controls the spraying mechanism to drive the steel pipe body to rotate, the coating flows along the inner wall of the steel pipe body to cover the inner wall of the steel pipe body, and the excess coating flows back into the collection tank along the inner wall of the steel pipe body.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0025] Reference Figure 1-6This utility model discloses a processing device for corrosion-resistant seamless steel pipes, comprising a steel pipe body 10, a first clamping mechanism 11 installed on the outer side of the steel pipe body 10, and the steel pipe body 10 being clamped by the first clamping mechanism 11. A spraying mechanism 7 is provided at one end of the steel pipe body 10, and one end of the steel pipe body 10 extends into and is clamped by the spraying mechanism 7. A drive motor 9 is fixedly connected to the end of the spraying mechanism 7 away from the first clamping mechanism 11. Supports are provided at the bottom of the first clamping mechanism 11 and the spraying mechanism 7. Mechanism 4, and the first clamping mechanism 11 and the spraying mechanism 7 are both installed on the support mechanism 4. The bottom of the support mechanism 4 is fixedly connected to the support leg 2. A collection tank 1 is fixedly connected to one side of the support leg 2. The collection tank 1 is located on the side of the first clamping mechanism 11 away from the spraying mechanism 7. A paint pump 3 is fixedly connected to the surface of the support leg 2. The input end of the paint pump 3 is connected to the bottom of the collection tank 1. An infusion hose 5 is fixedly connected to the output end of the paint pump 3. The end of the infusion hose 5 away from the paint pump 3 is installed on the spraying mechanism 7.

[0026] The spraying mechanism 7 consists of a housing 15, a second clamping mechanism 16, a drive disk 17, a connecting cover 18, a support gear 19, and a spray head 20. The lower middle part of the housing 15 is rotatably connected to the support mechanism 4. The support gear 19 and the drive disk 17 are rotatably connected within the housing 15. An external gear ring is fixedly connected to the surface of the drive disk 17, and one end of the drive disk 17 penetrates through the housing 15. Multiple support gears 19 are provided and equidistantly surround the outside of the drive disk 17, and the support gears 19 mesh with the drive disk 17. The second clamping mechanism 16 is fixedly connected to one end of the housing 15, and the second clamping mechanism 16 is fixedly connected to the drive disk 17 facing the first clamping mechanism 11. On one side, the connecting cover 18 is fixedly connected to the end of the housing 15 away from the second clamping mechanism 16. The nozzle 20 is installed on the middle of the end of the drive disk 17 that passes through the housing 15, and the interface of the nozzle 20 passes through the middle of the drive disk 17 and the connecting cover 18 in sequence. The interface of the nozzle 20 is fixedly connected to the connecting cover 18, and the outer side of the interface of the nozzle 20 is rotatably connected to the drive disk 17. The interface of the nozzle 20 is fixedly connected to the infusion tubing 5. The drive motor 9 is fixedly connected to the surface of the connecting cover 18, and the output end of the drive motor 9 passes through the connecting cover 18 and is rotatably connected to the connecting cover 18. The output end of the drive motor 9 is fixedly connected to any one of the rotating shafts of the multiple support gears 19. The nozzle 20 sprays anti-corrosion coating onto the inner wall of the seamless steel pipe. The drive motor 9 and the support gear 19 cooperate to make the drive disk 17 drive the second clamping mechanism 16 to rotate, causing the steel pipe body 10 clamped by the second clamping mechanism 16 to rotate, so that the anti-corrosion liquid is distributed to various parts of the inner wall of the steel pipe body 10.

[0027] The support mechanism 4 consists of a mounting frame 12, a support frame 13, and a hydraulic rod 14. The support leg 2 is fixedly connected to the bottom of the support frame 13. The mounting frame 12 and the hydraulic rod 14 are fixedly connected to the upper end of the support frame 13, and the mounting frame 12 and the hydraulic rod 14 are located on both sides of the support frame 13. The bottom of the first clamping mechanism 11 is rotatably connected to the middle of the upper end of the mounting frame 12. The upper end of the hydraulic rod 14 is rotatably connected to the middle of the lower end of the spraying mechanism 7. The hydraulic rod 14 pushes the spraying mechanism 7 upward, causing one end of the steel pipe body 10 to rise, so that the excess anti-corrosion coating in the steel pipe body 10 flows out through the lower end of the steel pipe body 10 to the collection tank 1 for recycling.

[0028] A spring connector 8 is rotatably connected to the end of the spraying mechanism 7 away from the first clamping mechanism 11, and the spring connector 8 is rotatably connected to the connecting cover 18. A support plate 6 is rotatably connected to the end of the spring connector 8 away from the spraying mechanism 7, and the bottom of the support plate 6 is fixedly connected to the support mechanism 4. After the spring connector 8 causes the hydraulic rod 14 to drive the spraying mechanism 7 to descend and reset, it pulls the spraying mechanism 7 to be set vertically, so that when the seamless steel pipe is put in later, one end of the seamless steel pipe can be put into the coating mechanism.

[0029] The first clamping mechanism 11 consists of a top plate 21, an upper clamping frame 22, and a lower clamping frame 23. The bottom of the lower clamping frame 23 is rotatably connected to the mounting frame 12. Two guide posts 25 are symmetrically fixedly connected to the upper end of the lower clamping frame 23. The top plate 21 is fixedly connected to the upper end of the two guide posts 25. The upper clamping frame 22 is located between the top plate 21 and the lower clamping frame 23, and the guide posts 25 pass through the upper clamping frame 22 and are slidably connected to the upper clamping frame 22. The upper clamping frame 22 and the lower clamping frame... The top plate 21 is symmetrically arranged with an adjusting bolt 26 at its upper end. The lower end of the adjusting bolt 26 passes through the top plate 21 and is threadedly connected to it. The lower end of the adjusting bolt 26 is rotatably connected to the upper end of the upper clamping frame 22. The second clamping mechanism 16 and the first clamping mechanism 11 have the same structure. The adjusting bolt 26 pushes the upper clamping frame 22 down to cooperate with the lower clamping frame 23 to clamp the steel pipe body 10, preventing the steel pipe body 10 from falling out of the device during the painting process.

[0030] The lower clamping frame 23 and the upper clamping frame 22 are provided with an arc surface in the middle. Several support rollers 24 are rotatably connected in the arc surface of the lower clamping frame 23 and the upper clamping frame 22 in the first clamping mechanism 11. The arc surface allows the first clamping mechanism 11 and the second clamping mechanism 16 to fully contact the surface of the steel pipe body 10. The support rollers 24 reduce the wear between the surface of the steel pipe body 10 and the first clamping mechanism 11 when the steel pipe body 10 rotates.

[0031] The lower clamping frame 23 in the second clamping mechanism 16 is fixedly connected to the drive disk 17, and the nozzle 20 is located between the lower clamping frame 23 and the upper clamping frame 22 in the second clamping mechanism 16. The nozzle 20 has an upward nozzle, so that when the drive disk 17 rotates, it drives the steel pipe body 10 to rotate through the second clamping mechanism 16. The upward nozzle of the nozzle 20 causes the anti-corrosion coating to flow from the inner wall of the high end of the steel pipe body 10 to the low end.

[0032] The surface of the support roller 24 is coated with an anti-slip coating. The anti-slip coating increases the friction of the support roller 24 surface, preventing the steel pipe body 10 from sliding in the first clamping mechanism 11 and the second clamping mechanism 16 after the device is tilted, which would cause the anti-corrosion coating sprayed by the nozzle 20 to be sprayed out from the gap between the steel pipe body 10 and the drive disk 17.

[0033] Working principle: In use, the first clamping mechanism 11 is straightened, and then one end of the seamless steel pipe is passed through the first clamping mechanism 11 from the side away from the spraying mechanism 7 until the end of the seamless steel pipe facing the spraying mechanism 7 passes through the second clamping mechanism 16 and is in contact with the surface of the drive plate 17. Then, by rotating the adjusting bolt 26, the upper clamping frame 22 of the first clamping mechanism 11 and the lower clamping frame 23 of the second clamping mechanism 16 clamp the seamless steel pipe. Then, the hydraulic rod 14 pushes the spraying mechanism 7 to rise, causing the seamless steel pipe to tilt, and the paint pump 3 will... The anti-corrosion coating in the collection tank 1 is delivered through the infusion hose 5 and sprayed onto the inner wall of the seamless steel pipe body 10 through the nozzle 20. At the same time, the drive motor 9 drives the support gear 19 to rotate, so that the drive disc 17 drives the seamless steel pipe to rotate through the second clamping mechanism 16, so that the anti-corrosion coating is completely distributed on all parts of the inner wall of the seamless steel pipe. During the rotation of the seamless steel pipe, excess anti-corrosion coating flows from the seamless steel pipe into the collection tank 1. After the spraying is completed, the coating pump 3 stops working, and the seamless steel pipe continues to work until there is no excess anti-corrosion coating flowing out of the seamless steel pipe.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
