Description

Technical Field

[0001] The present invention relates to the technical field of wind power tower processing, and specifically to a rust removal device for wind power tower processing. Background Art

[0002] The production process flow of a wind power tower is generally as follows: cutting with a numerical control cutting machine, beveling is required for thick plates. After the plate is rolled into shape by a rolling machine, spot welding, positioning are carried out. After confirmation, the internal and external longitudinal seams are welded. After roundness inspection, if there are problems, secondary rounding is carried out. After the single-section cylinder body welding is completed, the hydraulic assembly roller frame is used for assembly spot welding, and then the internal and external circumferential seams are welded. After the straightness and other tolerances are inspected, the flange is welded. After weld nondestructive testing and flatness inspection, sandblasting and painting treatments are carried out. After the internal parts are installed and the finished product inspection is completed, it is transported to the installation site.

[0003] Generally, when processing a wind power tower, multiple cylinder bodies are spliced and then welded into a group of large wind power towers. Each single cylinder body is generally curled and then compensated and welded at the connecting strip to form a circular cylinder. However, during the processing, the cycle is long, and the strip-shaped welds of some cylinder bodies are prone to rusting. Subsequently, the rust spots need to be polished for painting. However, since the strip-shaped welds are welded in subsequent production, the weld areas are often in an arc-shaped profile and not on the same horizontal plane. At this time, manual processing is required at this place. This method not only has a low processing efficiency but also has areas that are missed during processing.

[0004] Therefore, the present invention proposes a rust removal device for wind power tower processing. Summary of the Invention

[0014] 2. In the present invention, the camera will identify the rust spot area around the tower barrel weld prior to grinding wheels two and three. When a relatively large rust spot area is identified, air cylinder one will pull the U-shaped rod, ultimately causing shaft four to drive bevel gear two and bevel gear one to mesh and drive each other, enabling grinding wheels four and five to rotate. The outer wall surfaces of grinding wheels four and five are in contact with the outer wall of the tower barrel. Cooperating with grinding wheels one, two, and three, when the rust spot area is too large, this device can effectively increase the grinding area for the rust spots, ensuring a targeted grinding method for rust spots of various areas and having good applicability.

[0025] Please refer to Figures 1-8 , the present invention provides a technical solution: a rust removal device for processing wind power tower barrels, including:

[0026] Embodiment 1

[0027] Base 1, a sliding seat 2 is provided above the base 1, the sliding seat 2 is slidably connected to the base 1, a frame body 3 is provided above the sliding seat 2 and is slidably connected thereto, towing hooks 4 are provided on both sides of the sliding seat 2, and the side surface of the towing hook 4 is fixedly connected to the sliding seat 2; when the base 1 is parallel to the tower barrel, the staff can connect an external towing device to the towing hook 4, and then drive the sliding seat 2 to slide on the base 1 to ensure the parallel relationship between the sliding seat 2 and the tower barrel.

[0028] Above the frame body 3, there are a first grinding wheel 5, a second grinding wheel 6 and a third grinding wheel 7. The horizontal central axis of the first grinding wheel 5 is located in the middle position between the second grinding wheel 6 and the third grinding wheel 7, and is aligned with the weld center line of the tower barrel. The outer wall surfaces of the second grinding wheel 6 and the third grinding wheel 7 are tangent to the weld edge area of the tower barrel. Inside the first grinding wheel 5, the second grinding wheel 6 and the third grinding wheel 7, there are respectively a first shaft body 8, a second shaft body 9 and a third shaft body 10. The first grinding wheel 5, the second grinding wheel 6 and the third grinding wheel 7 are respectively fixedly connected to the first shaft body 8, the second shaft body 9 and the third shaft body 10. The outer wall of the first shaft body 8 is provided with a first connecting rod 11 and is rotatably connected thereto. The other end of the first connecting rod 11 is fixedly connected to the frame body 3. The outer walls of the second shaft body 9 and the third shaft body 10 are provided with connecting blocks 12 and are rotatably connected thereto. One side of the connecting block 12 is fixedly connected to the frame body 3. By using the tangency relationship between the second grinding wheel 6 and the third grinding wheel 7 and the weld area of the tower barrel, the second grinding wheel 6 and the third grinding wheel 7 in the grinding state are fitted to the arc surface of the weld area, ensuring a good rust removal effect.

[0029] Further, universal shafts 13 are provided on the outer walls at both ends of the first shaft body 8. A fourth shaft body 14 is provided inside the universal shaft 13. The two ends of the universal shaft 13 are respectively fixedly connected to the first shaft body 8 and the fourth shaft body 14. There are two fourth shaft bodies 14 in total. The outer wall of the fourth shaft body 14 is provided with a second connecting rod 15 and is rotatably connected thereto. One end of the second connecting rod 15 is fixedly connected to the frame body 3. The fourth shaft body 14 above the first shaft body 8 is driven by a belt to interact with the second shaft body 9, and the fourth shaft body 14 below the first shaft body 8 is driven by a belt to interact with the third shaft body 10. A motor 16 is provided above the frame body 3 and is fixedly connected thereto. The rotating shaft of the motor 16 is driven by a belt to interact with the first shaft body 8. Through the grinding cooperation of the first grinding wheel 5, the second grinding wheel 6 and the third grinding wheel 7, the weld area of the tower barrel is precisely rust-removed.

[0030] During use, the operator can drive an external traction device to slowly slide the sliding seat 2 above the base 1, and at the same time start the motor 16, so that the motor 16 drives the first shaft 8 and the first grinding wheel 5 to rotate through a belt. At the same time, the first shaft 8 drives the fourth shaft 14 to rotate through a universal shaft 13, and then drives the second shaft 9 and the third shaft 10 to rotate through a belt, so that the first grinding wheel 5, the second grinding wheel 6 and the third grinding wheel 7 rotate synchronously. As the sliding seat 2 drives the frame 3 to slide, the second grinding wheel 6 and the third grinding wheel 7 will polish the upper and lower edge lines of the weld first, and the adhesion of the second grinding wheel 6 and the third grinding wheel 7 to the weld will enhance the rust removal and polishing effect. After the second grinding wheel 6 and the third grinding wheel 7 finish polishing the weld, the first grinding wheel 5 located between the second grinding wheel 6 and the third grinding wheel 7 will supplement the rust on the central area of the weld. By cooperating with the polishing effects of the first grinding wheel 5, the second grinding wheel 6 and the third grinding wheel 7, stable and precise rust removal and polishing effects are achieved on the upper, middle and lower parts of the weld. Compared with the prior art, the problem of the arc-shaped surface in the weld area is overcome. This method not only has a high processing efficiency, but also can polish all areas of the weld, improving the rust removal quality.

[0031] Further, a fourth grinding wheel 17 and a fifth grinding wheel 18 are provided on one side of the frame 3, and a switching unit 19 for driving the fourth grinding wheel 17 and the fifth grinding wheel 18 to polish the outer wall surface of the tower barrel is provided above the frame 3. Through the switching unit 19, large-area rust spots on the tower barrel wall are automatically removed and polished.

[0032] The switching unit 19 includes transmission members 20 at the end of the fourth grinding wheel 17. There are two groups of transmission members 20, which are respectively used to drive the rotation of the fourth grinding wheel 17 and the fifth grinding wheel 18. The transmission member 20 includes a connecting shaft 21 inside the fourth grinding wheel 17. There are two connecting shafts 21, and the other one is inside the fifth grinding wheel 18. A first bevel gear 22 is provided on the outer wall of the connecting shaft 21 and is fixedly connected thereto. A second bevel gear 23 is provided on the outer wall of the fourth shaft 14 and is fixedly connected thereto. The first bevel gear 22 and the second bevel gear 23 are meshed with each other in the horizontal direction. A U-shaped rod 24 is provided on the outer wall of the connecting shaft 21 and is rotatably connected thereto. The U-shaped rod 24 passes through the frame 3 and is slidably connected thereto, and the other end of the U-shaped rod 24 is rotatably connected to the connecting shaft 21 inside the fifth grinding wheel 18. The U-shaped rod 24 can drive the connecting shaft 21 to move horizontally.

[0033] A connecting piece 25 is provided on the side of the U-shaped rod 24 and fixedly connected thereto, a cylinder 26 is provided on one side of the connecting piece 25 and fixedly connected thereto, a side of the cylinder is fixedly connected to the frame 3, a fixing rod 27 is provided on one side of the frame 3 and fixedly connected thereto, a camera 28 is provided above the fixing rod 27 and fixedly connected thereto, the camera 28 has the function of detecting the area of ​​rust spots, and the transmitter inside the camera 28 is electrically connected to the cylinder 26; when the camera 28 detects that there are many rust spots on the wall of the tower, it will send a start signal to the cylinder 26, driving the cylinder 26 to pull the U-shaped rod 24 to move laterally inside the frame 3.

[0034] In addition, an absorption unit 29 for collecting the debris after grinding is provided above the frame 3. The absorption unit 29 includes an absorption box 30 located on one side of the grinding wheel 5. A collection box 31 is provided below the absorption box 30 and is fixedly connected thereto. The absorption box 30 and the collection box 31 are connected to each other. The debris entering the absorption box 30 will fall into the collection box 31 due to gravity. A connecting rod 32 is provided on the side of the absorption box 30 and is fixedly connected thereto. The end of the connecting rod 32 is fixedly connected to the frame 3. An air pipe 33 is provided on the outer wall of the box 30 and is connected thereto. A filter is provided between the absorption box 30 and the air pipe 33 to block the inhaled debris. A fan 34 is provided at the end of the air pipe 33. The air inlet of the fan 34 is connected to the air pipe 33. The fan 34 is fixedly connected to the frame 3 through a fixed frame. The rotating shaft of the fan 34 is connected to the rotating shaft of the motor 16 through a coupling. The started motor 16 can drive the fan 34 to operate, and then the absorption box 30 has good suction through the air pipe 33.

[0035] When in use, the camera 28 located above the fixed rod 27 will identify the rust spot area around the tower weld before the grinding wheel 2 6 and the grinding wheel 3 7. When the rust spot area is identified to be large, the staff can stop moving the slide 2 and turn off the motor 16. The camera 28 will send a start signal to the cylinder 1 26, so that the cylinder 1 26 pulls the U-shaped rod 24, and the U-shaped rod 24 will drive the connecting shaft 21 and the bevel gear 1 22 at both ends to move, and finally the bevel gear 1 22 and the bevel gear 2 23 are meshed with each other. At this time, the motor 16 can be started again to drive the slide 2 to continue sliding. During this process, shaft body four 14 will drive bevel gear two 23 and bevel gear one 22 to engage with each other, so that grinding wheels four 17 and five 18 connected to the outer walls of the two shafts 21 rotate, and the outer wall surfaces of grinding wheels four 17 and five 18 fit with the outer wall of the tower, and cooperate with grinding wheels one 5, grinding wheels two 6 and grinding wheels three 7. When it is detected that the area of ​​rust spots is too large, the grinding area of ​​rust spots by this equipment can be effectively increased, ensuring that targeted grinding methods are used for rust spots of various areas, and having good applicability.

[0036] According to the above embodiment, embodiment 2

[0037] The grinding wheel four 17 includes a grinding skin 37 and a rotating cylinder 38. The grinding skin 37 is wrapped around the outer wall of the rotating cylinder 38 and rotates with the rotating cylinder 38. The inside of the rotating cylinder 38 is filled with a rust remover. The wall of the rotating cylinder 38 is provided with a through groove 39, and the through groove 39 passes through the grinding skin 37 and the rotating cylinder 38 for the rust remover to flow downward from the through groove 39. A retaining strip 40 is provided on the inner wall of the rotating cylinder 38. A connecting strip 41 is provided at the end of the retaining strip 40 and is fixedly connected thereto. The connecting strip 41 passes through the rotating cylinder 38 and an arc-shaped strip 42 is provided at the end. The end of the connecting strip 41 is fixedly connected to the arc-shaped strip 42. An electromagnet 43 is provided on the side surface of the arc-shaped strip 42 and is fixedly connected thereto. A magnet 44 is provided at the end of the rotating cylinder 38 and is fixedly connected thereto. When the electromagnet 43 is in the energized state, a magnetic force that attracts the magnet 44 is generated. The electromagnet 43 is electrically connected to the first cylinder 26. When the first cylinder 26 pulls the U-shaped rod 24 to displace, the electromagnet 43 is in the energized state.

[0038] When the electromagnet 43 and the magnet 44 are in the adsorbed state, the retaining strip 40 completely blocks the through groove 39. A spring 45 is provided on the side surface of the electromagnet 43. A fixing piece 46 is provided at the end of the spring 45. Both ends of the spring 45 are fixedly connected to the fixing piece 46 and the electromagnet 43 respectively. The side surface of the fixing piece 46 is fixedly connected to the rotating cylinder 38. The attractive force between the electromagnet 43 and the magnet 44 in the energized state is greater than the elastic force of the spring 45.

[0039] When the grinding wheel four 17 and the grinding wheel five 18 are in the non-rotating state, the rust remover inside the rotating cylinder 38 will flow downward from the bottom of the rotating cylinder 38 prior to the grinding wheel two 6 and the grinding wheel three 7 and drip onto the surface of the tower barrel to be polished, which can provide favorable conditions for the subsequent rust removal and grinding of the grinding wheel two 6 and the grinding wheel three 7, thereby improving the grinding quality. When it is necessary to increase the grinding area, the first cylinder 26 will send an energizing signal to the electromagnet 43 while pulling the U-shaped rod 24 to displace, so that the electromagnet 43 is in the energized state, and then the electromagnet 43 and the magnet 44 will adsorb each other. The adsorption force will cause the electromagnet 43 to drive the arc-shaped strip 42 and the connecting strip 41 to rotate until the retaining strip 40 completely blocks the through groove 39, preventing the rust remover inside the rotating cylinder 38 from flowing out from its inside. Then the grinding wheel four 17 and the grinding wheel five 18 can smoothly participate in the grinding work of the rust spots on the tower barrel, ensuring that under the appropriate auxiliary action of the rust remover, there is still a good rust removal effect.

[0040] According to the above embodiments, Embodiment Three

[0041] Above the camera 28, a laser instrument 35 is provided and fixedly connected thereto. The laser instrument 35 has the function of measuring the distance from the tower barrel wall surface. Above the sliding seat 2, a second cylinder 36 is provided and fixedly connected thereto. The end of the second cylinder 36 is fixedly connected to the frame 3. The frame 3 is slidably connected to the sliding seat 2. The second cylinder 36 is electrically connected to the laser instrument 35;

[0042] The walls of the first grinding wheel 5, the second grinding wheel 6, the third grinding wheel 7, the fourth grinding wheel 17, and the fifth grinding wheel 18 in this device are all elastic and can withstand a certain amount of extrusion. When the laser instrument 35 is on the way of displacement, when the thickness of the rust spots in the area involved by the ray is relatively thick, the distance detected by the laser instrument from the tower barrel will also be smaller than the distance in the normal area, indicating that there are relatively thick rust spots in this area. At this time, the laser instrument 35 will send a start signal to the second cylinder 36, causing the second cylinder 36 to drive the frame 3 to displace a rated distance on the sliding seat 2, so that the multiple grinding wheels are slightly extruded, thereby strengthening the friction between the grinding wheels and the tower barrel wall surface, making the rust removal force match the relatively thick rust spots, further enhancing the applicability of the rust removal device, and achieving a better rust removal effect.

[0043] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to this process, method, article or device.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
