Description

Technical Field

[0001] This utility model belongs to the field of wind turbine blade operation and maintenance technology, and specifically relates to a suspended basket for wind turbine blade operation and maintenance. Background Technology

[0002] As the core component of wind turbines, wind turbine blades are exposed to complex natural environments for extended periods, making them susceptible to damage such as surface coating peeling, leading-edge corrosion, and structural cracks. If these damages are not repaired promptly, they can significantly reduce wind energy conversion efficiency and may even lead to catastrophic accidents such as blade breakage. Among these methods, suspended platform operations are an irreplaceable approach for large-scale repair projects.

[0003] Traditional suspended platform structures typically consist of a base, safety railings, a lifting mechanism, and connecting components, forming a relatively enclosed cylindrical or cage-like space. When maintenance personnel enter the suspended platform, various tools and materials can only be piled directly on the platform's floor, occupying the already limited working area and compressing the effective activity space. Utility Model Content

[0004] To address the problem that when maintenance personnel enter the suspended platform, various tools and materials can only be directly piled on the bottom plate of the platform, occupying the already limited working area and compressing the effective activity space, this utility model proposes a suspended platform for wind turbine blade operation and maintenance to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a suspended basket for wind turbine blade operation and maintenance, including a base plate, a guardrail fixedly connected to the top of the base plate, a fixing plate fixedly connected to the outer surface of the guardrail, a folding assembly provided on the outer surface of the fixing plate, a limiting assembly and a sliding assembly respectively provided inside the folding assembly, the folding assembly is used to form a storage box, and the limiting assembly is used to limit and fix the folding assembly.

[0006] Furthermore, the folding assembly includes a first rotating plate, which is rotatably connected to a fixed plate. A second rotating plate is rotatably connected to the outer surface of the first rotating plate, and a side plate is rotatably connected to the outer surface of the second rotating plate. There are two sets of side plates, and pins are rotatably connected to the first rotating plate, the second rotating plate, and the side plates.

[0007] Furthermore, the limiting component includes a first push block, a spring is fixedly connected to the top of the first push block, and a limiting rod is fixedly connected to the bottom of the first push block. The first push block and the limiting rod are slidably connected inside the side plate, and the limiting rod passes through the side plate and is inserted into the first rotating plate.

[0008] Furthermore, the sliding assembly includes a sliding plate, on the outer surface of which a second push block and a limiting plate are fixedly connected respectively, and a sliding groove is provided inside the side plate, wherein the sliding plate, the second push block and the limiting plate are all slidably connected inside the sliding groove.

[0009] Furthermore, a straight plate is rotatably connected to the outer surface of the first rotating plate, and a hook plate is fixedly connected to the outer surface of the fixed plate. The straight plate is used to insert into the hook plate, and there are two sets of both the straight plate and the hook plate.

[0010] Furthermore, a rotating rail is rotatably connected to the outer surface of the guardrail, a limiting seat is fixedly connected to the outer surface of the guardrail, a rotating seat is rotatably connected to the outer surface of the limiting seat, and a bolt is threadedly connected to the outer surface of the rotating seat. The bolt passes through the rotating seat and is threadedly connected to the limiting seat.

[0011] Furthermore, the outer surface of the guardrail is fixedly connected with lifting lugs.

[0012] This utility model has the following beneficial effects: This invention connects a folding component and a limiting component. When not in use, the folding component can be stored inside a fixed plate, reducing the overall space occupied and facilitating transportation. After the worker climbs onto the base plate, the folding component is unfolded, allowing it to rotate out of the fixed plate and form a box. After the limiting component passes through the folding component, the rotation trend of the folding component is blocked by the limiting component, keeping the folding component in a fixed shape. At this time, the worker can put tools into the folding component, avoiding the tools occupying the space on the top of the base plate.

[0013] This invention moves a sliding plate by pushing a second pusher block. The sliding plate moves a limiting plate along a groove. The limiting plate on the outer surface of the sliding plate can only slide within the groove, which limits the movement distance of the sliding plate and prevents it from coming out of the side plate. When the sliding plate slides out of the side plate and abuts against the fixed plate, it fills the gap between the side plate and the fixed plate, preventing the tool on the top of the first rotating plate from falling out of this gap.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0020] Please see Figures 1-9 As shown, this utility model is a hanging basket for wind turbine blade operation and maintenance, including a base plate 1. A guardrail 2 is fixedly connected to the top of the base plate 1. A fixing plate 3 is fixedly connected to the outer surface of the guardrail 2. A folding assembly 4 is provided on the outer surface of the fixing plate 3. A limiting assembly 5 and a sliding assembly 6 are respectively provided inside the folding assembly 4. The folding assembly 4 is used to form a storage box. The limiting assembly 5 is used to limit and fix the folding assembly 4.

[0021] After the staff climbs onto the base plate 1, the guardrail 2 at the top of the base plate 1 acts as a barrier to prevent the staff from falling from the top of the base plate 1. Then, unfold the folding component 4 on the outer surface of the guardrail 2, assemble the folding component 4 into a box, and push the limiting component 5 to slide inside the folding component 4 to limit the folding component 4. Then push the sliding component 6 to slide inside the folding component 4, and the sliding component 6 fills the gap between the folding component 4 and the fixed plate 3. At this time, tools can be put into the folding component 4 to avoid occupying the moving space at the top of the base plate 1.

[0022] This utility model connects the folding component 4 and the limiting component 5. When not in use, the folding component 4 can be stored inside the fixed plate 3, which can reduce the overall space occupied and facilitate transportation. After the staff climbs onto the base plate 1, the folding component 4 is unfolded, so that the folding component 4 rotates out of the fixed plate 3 and forms a box. After the limiting component 5 passes through the folding component 4, the rotation trend of the folding component 4 will be blocked by the limiting component 5, so that the folding component 4 maintains a fixed shape. At this time, the staff can put the tools into the folding component 4 to avoid the tools occupying the space at the top of the base plate 1.

[0023] In one embodiment, the folding assembly 4 includes a first rotating plate 401, which is rotatably connected to the fixed plate 3. A second rotating plate is rotatably connected to the outer surface of the first rotating plate 401, and a side plate 403 is rotatably connected to the outer surface of the second rotating plate 402. There are two sets of side plates 403. A pin 404 is rotatably connected to each of the first rotating plate 401, the second rotating plate 402, and the side plate 403.

[0024] Rotate the first rotating plate 401, which in turn drives the second rotating plate 402 and the side plate 403 to rotate, so that the first rotating plate 401 rotates out of the fixed plate 3 and is perpendicular to the fixed plate 3. Then rotate the second rotating plate 402 to be perpendicular to the first rotating plate 401. Finally, rotate the two sets of side plates 403 out of the second rotating plate 402, so that the side plates 403, the second rotating plate 402 and the first rotating plate 401 are perpendicular to each other, thus forming a box. The staff puts the tools into this box to avoid the tools occupying the space on the top of the bottom plate 1.

[0025] In one embodiment, the limiting component 5 includes a first push block 501, a spring 502 fixedly connected to the top of the first push block 501, and a limiting rod 503 fixedly connected to the bottom of the first push block 501. The first push block 501 and the limiting rod 503 are slidably connected inside the side plate 403. The limiting rod 503 passes through the side plate 403 and is inserted into the first rotating plate 401.

[0026] Before rotating the side plate 403, push the first push block 501 inside the side plate 403 to move. The first push block 501 drives the limiting rod 503 to retract into the side plate 403. At the same time, the first push block 501 compresses the spring 502. Then rotate the side plate 403 to be perpendicular to the second rotating plate 402. After releasing the first push block 501, the spring 502 pushes the first push block 501 and the limiting rod 503 to move downward, so that the limiting rod 503 passes through the side plate 403 and is inserted into the first rotating plate 401. At this time, the limiting rod 503 can limit and fix the side plate 403 and the second rotating plate 402.

[0027] In one embodiment, the sliding component 6 includes a sliding plate 601, with a second push block 602 and a limiting plate 603 fixedly connected to the outer surface of the sliding plate 601. A sliding groove 604 is provided inside the side plate 403, and the sliding plate 601, the second push block 602 and the limiting plate 603 are all slidably connected inside the sliding groove 604.

[0028] The second pusher 602 is pushed, which causes the sliding plate 601 to slide in the groove 604 in the side plate 403, so that the sliding plate 601 abuts against the fixed plate 3, filling the gap between the fixed plate 3 and the side plate 403, preventing the worker's tools from falling out of the gap. The limiting plate 603 restricts the movement distance of the sliding plate 601, preventing the sliding plate 601 from coming out of the groove 604.

[0029] In one embodiment, for the first rotating plate 401, a straight plate 7 is rotatably connected to the outer surface of the first rotating plate 401, and a hook plate 8 is fixedly connected to the outer surface of the fixed plate 3. The straight plate 7 is used to insert into the hook plate 8, and there are two sets of both the straight plate 7 and the hook plate 8.

[0030] Pushing the second push block 602 causes the sliding plate 601 to retract into the side plate 403. Pushing the first push block 501 causes the limiting rod 503 to separate from the first rotating plate 401 to release the limiting fixation of the side plate 403. The side plate 403 is then retracted to the outer surface of the second rotating plate 402. The second rotating plate 402 is then rotated to the top of the first rotating plate 401. Subsequently, pushing the first rotating plate 401 causes the second rotating plate 402 and the side plate 403 to retract into the fixed plate 3. Rotating the straight plate 7 on the outer surface of the first rotating plate 401 allows it to engage with the hook plate 8, which can limit and fix the first rotating plate 401, preventing it from rotating out of the fixed plate 3.

[0031] In one embodiment, for the guardrail 2, a rotating railing 9 is rotatably connected to the outer surface of the guardrail 2, a limiting seat 10 is fixedly connected to the outer surface of the guardrail 2, a rotating seat 11 is rotatably connected to the outer surface of the limiting seat 10, and a bolt 12 is threadedly connected to the outer surface of the rotating seat 11. The bolt 12 passes through the rotating seat 11 and is threadedly connected to the limiting seat 10.

[0032] Rotate bolt 12 to separate it from limit seat 10. After releasing the limiting fixation of rotating seat 11 and limit seat 10, push rotating seat 11 to rotate it to separate it from rotating rail 9. At this time, the worker can pull rotating rail 9 to rotate and climb onto base plate 1. After climbing onto base plate 1, pull rotating rail 9 in the opposite direction to enter limit seat 10. Rotate rotating seat 11 to engage with the outer surface of limit seat 10. Passing bolt 12 through rotating seat 11 and limit seat 10 can limit rotating rail 9 and prevent unnecessary rotation of rotating rail 9.

[0033] In one embodiment, for the guardrail 2 described above, a lifting lug 13 is fixedly connected to the outer surface of the guardrail 2.

[0034] The lifting equipment is connected to the guardrail 2 via the lifting lug 13. The lifting lug 13 provides a connection position for the lifting equipment, making it easy to lift the guardrail 2 and the base plate 1.

[0035] Through the above technical solution, 1. By connecting the folding component 4 and the limiting component 5, the folding component 4 can be stored inside the fixed plate 3 when not in use, which can reduce the overall space occupied and facilitate transportation. After the worker climbs onto the base plate 1, the folding component 4 is unfolded, allowing it to rotate out of the fixed plate 3 and form a box. After the limiting component 5 passes through the folding component 4, the rotation tendency of the folding component 4 will be blocked by the limiting component 5, so that the folding component 4 maintains a fixed shape. At this time, the worker can put tools into the folding component 4, avoiding the tools occupying the space at the top of the base plate 1; 2. The sliding plate 601 is moved by pushing the second pusher 602. The sliding plate 601 drives the limiting plate 603 to slide along the slide groove 604. The limiting plate 603 on the outer surface of the sliding plate 601 can only slide within the slide groove 604, which can limit the movement distance of the sliding plate 601 and prevent the sliding plate 601 from coming out of the side plate 403. The sliding plate 601 slides out of the side plate 403 and abuts against the fixed plate 3. At this time, the sliding plate 601 can fill the gap between the side plate 403 and the fixed plate 3, preventing the tool on the top of the first rotating plate 401 from falling out of this gap.
