Description

Technical Field

[0001] The present invention relates to the technical field of wind power equipment sandblasting, and in particular to a wind power bearing cage sandblasting device and a use method thereof. Background Art

[0002] In the existing technology, small wind turbine bearing cages are usually sandblasted indoors, while large wind turbine bearing cages cannot be sandblasted indoors. In addition, the metal dust generated during the sandblasting process can easily form an explosive mixture in the closed cavity. Therefore, the current large wind turbine bearing cages lack a stable sandblasting preparation environment.

[0003] In addition, most existing sandblasting equipment uses a fixed multi-nozzle array or a single robotic arm operation mode. Full-coverage sandblasting of large wind turbine bearing cages with a diameter greater than 2m requires frequent adjustment of the spray gun angle and travel speed. The processing time of a single piece is as long as 4-6 hours, and the abrasive loss rate is as high as 30%-40%. In addition, the proportion of manual intervention is too high. During the sandblasting process of large wind turbine bearing cages, they usually rely on bracket support, and moving requires multiple people. Even if the bracket is equipped with rollers and other structures that facilitate the movement of the cage, the existing bracket cannot maintain stable support and limitation for the large wind turbine bearing cage, which often affects the sandblasting quality and greatly increases the workload of the operators.

[0004] Furthermore, traditional sandblasting processes for wind turbine bearing cage surface treatment are limited by factors such as low abrasive flow control precision, inappropriate nozzle trajectory planning, and workpiece clamping and positioning errors. This can easily lead to uneven cage surface roughness distribution, excessive or insufficient sandblasting intensity in some areas, and insufficient sandblasting uniformity and surface quality stability. For example, complex curved surfaces (such as pocket edges and rib intersections) are prone to under-blasting due to the limited abrasive incident angle, resulting in reduced adhesion of subsequent coatings. Repeated abrasive impact on flat surfaces can lead to over-blasting, causing microcracks or excessive material removal, impacting the cage's dimensional accuracy and fatigue life.

[0005] The above problems have seriously restricted the industrial application of sandblasting technology for wind power bearing cages, resulting in the inability to improve the product qualification rate and high comprehensive processing costs per piece. Summary of the Invention

The driving station 6 is provided with a driving station 6 rolling structure, and the wind power bearing holder 8 is arranged on the driving station 6 rolling structure; the clamping mechanism 7 is provided with a clamping mechanism 7 roller and a clamping wheel 701, and the wind power bearing holder 8 is arranged on the upper part of the clamping mechanism 7 roller, and the clamping wheel 701 is arranged on the upper part of the clamping mechanism 7 roller to clamp the upper edge of the wind power bearing holder 8; the first limiting mechanism 5 is arranged at the bottom of the wind power bearing holder 8 near the outside of the working window 4, and the first limiting mechanism 5 is provided with multiple first limiting rollers 501, and the multiple first limiting rollers 501 are vertically clamped on both sides of the wind power bearing holder 8.

[0015] Since in the existing technology, small wind turbine bearing retainers 8 are usually sandblasted indoors, while large wind turbine bearing retainers 8 cannot be sandblasted indoors, and the metal dust generated during the sandblasting process can easily form an explosive mixture in the closed cavity, the current large wind turbine bearing retainers 8 lack a stable sandblasting preparation environment.

[0016] In this embodiment, the cover body 2 is provided with a rectangular structure and a working window 4, and one end of the large wind turbine bearing holder 8 is extended into the interior of the cover body 2 through the working window 4 provided on the side of the cover body 2 for sandblasting. This can provide a stable sandblasting preparation environment for the large wind turbine bearing holder 8, thereby preventing the metal dust generated during the sandblasting process from forming an explosive mixture in the closed cavity and causing a safety accident.

[0017] Since the existing sandblasting equipment requires too much manual intervention during the sandblasting process, the large wind turbine bearing retainer 8 is usually supported by the bracket during sandblasting, and multiple people are needed to move it. Even if the bracket is provided with rollers and other structures that facilitate the movement of the bracket, the existing bracket cannot maintain stable support and limitation for the large wind turbine bearing retainer 8, which often affects the sandblasting quality and greatly increases the workload of the operators.

[0018] In this embodiment, a plurality of drive stations 6 and a clamping mechanism 7 are provided on the outside of the cover body 2. By placing the large wind turbine bearing holder 8 horizontally on the drive station 6, the position of the drive station 6 can be set around the bottom of the large wind turbine bearing holder 8 according to the size of the large wind turbine bearing holder 8 so that the drive station 6 can achieve stable support for the holder. At the same time, a drive station 6 rolling structure is provided on the drive station 6. The wind turbine bearing holder 8 is arranged on the drive station 6 rolling structure. While relying on the weight of the holder, the drive station 6 rolling structure has a certain friction force, so that the drive station 6 rolling structure can drive the entire wind turbine bearing holder 8 to rotate, replacing the traditional mobile wind turbine bearing holder 8 placed on an immovable bracket that needs to be manually lifted and moved for sandblasting. While saving manpower, it can achieve stable and uniform speed operation of the wind turbine bearing holder 8, thereby improving the sandblasting quality.

[0019] In addition, a first limiting structure is also provided, which clamps the two side edges of the wind turbine bearing holder 8 to support and limit it in the horizontal direction, so that when the holder rotates on the drive station 6, no horizontal displacement and shaking will occur during the rotation process, further ensuring the stability of the wind turbine bearing holder 8 during rotation and sandblasting, thereby avoiding uneven distribution of the holder surface roughness, excessive or insufficient sandblasting intensity in local areas, and insufficient sandblasting uniformity and surface quality stability.

[0020] In addition, a clamping mechanism 7 is provided between multiple drive stations 6, and a clamping mechanism 7 roller and a clamping wheel 701 are provided on the clamping mechanism 7. The clamping mechanism 7 can clamp the wind turbine bearing holder 8. Specifically, the wind turbine bearing holder 8 is placed on the clamping mechanism 7 roller and cooperates with the drive station 6 to achieve its stable rotation. The clamping wheel 701 is set on the upper side edge of the wind turbine bearing holder 8, and is corresponding to the clamping mechanism 7 roller to clamp the wind turbine bearing holder 8 in the middle. Among them, the clamping wheel 701 can apply a certain pre-tightening force downward to the wind turbine bearing holder 8, so that it can avoid bouncing and shaking during the sandblasting process, thereby achieving its stable rotation while ensuring the sandblasting quality.

[0021] Furthermore, an exhaust and cooling assembly 1 is provided on the upper portion of the cover 2, and inspection windows 3 are provided on both sides of the cover 2. The length of the working window 4 is greater than the diameter of the wind turbine bearing holder 8, and the height of the working window 4 is greater than the height of the wind turbine bearing holder 8. In this embodiment, the exhaust and cooling assembly 1 can operate to achieve exhaust and cooling during the sandblasting process. The size of the working window 4 is set to allow one end of the wind turbine bearing holder 8 to pass smoothly through the working window 4 and into the cover 2 for sandblasting. At the same time, the inspection window 3 is provided on the cover 2, which facilitates personnel to enter the cover 2 for maintenance.

[0022] Furthermore, the first limiting mechanism 5 includes a first limiting bracket, and a plurality of first limiting rollers 501 are slidably connected to the first limiting bracket; A second limiting mechanism 9 is provided inside the cover body 2, and the second limiting mechanism 9 includes a second limiting bracket. The second limiting bracket is provided with multiple roller assemblies supported at the bottom of the wind power bearing retainer 8, and the second limiting bracket is also slidably connected to multiple second limiting rollers that are vertically clamped on both sides of the wind power bearing retainer 8.

[0023] A second limiting mechanism 9 is set in the cover body 2 to further ensure the stability of the wind turbine bearing retainer 8 during the sandblasting process, wherein the first limiting bracket is slidably connected to multiple first limiting rollers 501, and the second limiting bracket is slidably connected to multiple second limiting rollers, which can be conveniently adjusted and clamped according to the wind turbine bearing retainer 8, thereby improving the adaptability and limiting stability of the device.

[0024] Furthermore, the sandblasting assembly is provided with a first nozzle assembly 17, a second nozzle assembly 11, a first baffle 13 and a second baffle 14, wherein the first baffle 13 and the second baffle 14 are both configured as arc-shaped plates; The first nozzle assembly 17 and the first baffle 13 are correspondingly arranged on both sides of the wind turbine bearing holder 8, and the second nozzle assembly 11 and the second baffle 14 are correspondingly arranged on both sides of the wind turbine bearing holder 8. The first nozzle assembly 17 and the second baffle 14 are arranged on the outside of the wind turbine bearing holder 8, and the second nozzle assembly 11 and the first baffle 13 are arranged on the inside of the wind turbine bearing holder 8. Since existing sandblasting equipment mostly uses a fixed multi-nozzle array or a single robotic arm operation mode, full-coverage sandblasting of large wind turbine bearing retainers 8 with a diameter greater than 2m requires frequent adjustment of the spray gun angle and travel speed. The processing time for a single piece is as long as 4-6 hours, and the abrasive loss rate is as high as 30%-40%.

[0025] In this embodiment, the sandblasting assembly is provided with a first nozzle assembly 17, a second nozzle assembly 11, a first baffle 13 and a second baffle 14. By correspondingly arranging the first nozzle assembly 17 and the first baffle 13 on both sides of the wind turbine bearing holder 8, the second nozzle assembly 11 and the second baffle 14 are correspondingly arranged on both sides of the wind turbine bearing holder 8, the first nozzle assembly 17 and the second baffle 14 are arranged on the outside of the wind turbine bearing holder 8, and the second nozzle assembly 11 and the first baffle 13 are arranged on the inside of the wind turbine bearing holder 8, thereby cooperating with the drive station 6 to achieve stable sandblasting on both sides of the wind turbine bearing holder 8 during rotation, thereby achieving full coverage sandblasting of the large wind turbine bearing holder 8 and reducing the workload of workers.

[0027] The positions of the first nozzle bracket assembly and the second nozzle bracket assembly are arranged in this way, so that the overall structure of the device is reasonable, and the different nozzle assemblies can efficiently achieve full coverage sandblasting of the wind turbine bearing retainer 8, and the various structures are easy to maintain and inspect.

[0028] Furthermore, the first nozzle bracket assembly is provided with a first drive motor 12, the first drive motor 12 is arranged on the top of the cover body 2, the output end of the first drive motor 12 is connected to the first drive connecting rod, the other end of the first drive connecting rod is connected to the first mounting connecting rod, the two ends of the first mounting connecting rod are connected to the first support frame, and the first support frame is arranged on the inner wall of the cover body 2; a first nozzle assembly 17 is provided in the middle of the first mounting connecting rod, the first nozzle assembly 17 is provided with a plurality of first nozzle brackets, the plurality of first nozzle brackets are slidably connected to the first mounting connecting rod, the plurality of first nozzle brackets can approach or move away from the first mounting connecting rod, and the first nozzle bracket is provided with a first nozzle; The second nozzle bracket assembly is provided with a second drive motor 15, which is arranged at the bottom of the cover body 2, and the output end of the second drive motor 15 is connected to the second drive link 21, and the other end of the second drive link 21 is connected to the second mounting link 22, and the two ends of the second mounting link 22 are connected to the second support frame 23, and the second support frame 23 is arranged on the inner wall of the cover body 2, and the second nozzle assembly 11 is arranged in the middle of the second mounting link 22, and the second nozzle assembly 11 is provided with a plurality of second nozzle 24 brackets, and the plurality of second nozzle 24 brackets are slidably connected to the second mounting link 22, and the plurality of second nozzle 24 brackets can approach or move away from the second mounting link 22, and the second nozzle 24 is provided on the second nozzle 24 bracket.

[0029] In this embodiment, if Figure 7As shown, the output end of the second drive motor 15 is connected to the turntable 20, the second drive link 21 is vertically arranged and eccentrically connected to the turntable 20, and a slide link structure is provided at the connection between the second drive link 21 and the turntable 20, so that when the output end of the second drive motor 15 rotates, the second drive link 21 can be driven to move up and down, and the other end of the second drive link 21 is connected to the transversely arranged second mounting link 22, and a slide link structure is also provided at the connection position between the second drive link 21 and the second mounting link 22. The two ends of the second mounting link 22 are rotatably connected to the second mounting member, so that the second drive link 21 can drive the second mounting link 22 to rotate, thereby driving the second nozzle 24 to swing, and at the same time, multiple second nozzle 24 brackets can slide on the second mounting link 22 to adjust the lateral distance of the second nozzle 24, and the second nozzle 24 bracket is arranged as a multi-link structure, and the installation position of the link can be adjusted between the multi-link structure to adjust the spacing distance between the second nozzle 24 and the wind turbine bearing mounting frame. Similarly, the first drive motor 12, the first drive connecting rod, the first mounting connecting rod, the first mounting frame, the first nozzle bracket and the first nozzle are arranged in the same manner as described above, except that the first drive motor 12 is arranged at the top of the cover body 2, and is distinguished from the second drive motor 15 arranged at the bottom of the cover body 2, while facilitating the arrangement of other structures.

[0030] With such an arrangement, full coverage and efficient sandblasting of wind turbine bearing retainers 8 of different sizes can be achieved.

[0031] In this embodiment, the first baffle 13 and the second baffle 14 are both set to arc-shaped plates to adapt to the contour of the wind turbine bearing holder 8, and are more closely fitted with the contour of the wind turbine bearing holder 8, thereby preventing sandblasting from splashing. At the same time, a thickened plate 18 can be set on the baffle to strengthen the strength of the baffle; compared with the existing sandblasting equipment that mostly adopts a fixed multi-nozzle array or a single robotic arm operation mode, the nozzle rental assembly and the baffle can be adjusted based on wind turbine bearing racks of different sizes. According to the contour of the wind turbine bearing holder 8, the connection position of multiple second nozzles 24 brackets and the second mounting link 22 can be slid and adjusted, and multiple second nozzles 24 brackets can be adjusted so that the multiple second nozzles 24 are based on the outer contour of the wind turbine bearing holder 8 and the interval distance of the wind turbine bearing holder 8 is consistent. The adjustment method of the first nozzle is the same as the adjustment method of the second nozzle 24, so that the interval distance between the multiple first nozzles and the wind turbine bearing holder 8 is consistent, thereby ensuring the sandblasting quality and preventing the problem of inconsistent sandblasting quality of different parts of the wind turbine bearing holder 8 caused by inconsistent distances. For full coverage sandblasting of large wind turbine bearing cages 8, there is no need to frequently adjust the spray gun angle and travel speed, which reduces processing time, reduces abrasive loss rate, and improves work efficiency. Furthermore, the sand discharge mechanism includes a sand discharge bottom plate 16 connected to the bottom of the cover body 2, and the sand discharge bottom plate 16 is arranged in a W-shaped structure.

The sand discharge bottom plate 16 is vibrated by the vibration motor 10 so that the sand in the sandblasting process enters the sand discharge flow channel 19 at the bottom through multiple leakage holes. The sand discharge flow channel 19 formed by the folding cover plate and the sand discharge bottom plate 16 can prevent the sand from splashing and leaking during the vibration process, and the sand is concentrated and flows out from one side for collection, thereby realizing the recovery of the sand.
