Description

Technical Field

[0001] This utility model relates to the field of wind farms, and in particular to an auxiliary device for the maintenance of wind farm platform units. Background Technology

[0002] An existing patent (publication number: CN105522525B) discloses a thrust bearing maintenance platform, including a support platform for supporting the thrust bearing. A horizontal moving assembly for horizontally moving the thrust bearing is disposed on the platform surface. Multiple height-adjustable support column assemblies are disposed below the support platform, and pulleys are disposed at the bottom of the support column assemblies. The horizontal moving assembly includes multiple rollers mounted on the support platform. The multiple rollers are distributed on both sides of the support platform and are evenly distributed along the length direction of the support platform, with the rolling direction of the rollers consistent with the length direction of the support platform. The support column assembly includes a height adjuster, an upper support column connecting to the support platform, and a lower support column connecting to the pulleys. The upper and lower support columns are connected by the height adjuster. However, the length of this device platform is fixed and cannot be adjusted according to the usage scenario. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a wind farm platform unit maintenance auxiliary device that allows the No. 2 maintenance platform to be stored under the No. 1 maintenance platform during storage, with an overall area only close to that of a single maintenance platform. It is suitable for maintenance scenarios with limited space, such as engine rooms and workshops. After unfolding and splicing, the platform can be quickly extended without the need for additional splicing of other equipment. It can expand the operating space within a fixed area and avoid the maintenance process being hindered due to limited space.

[0004] The objective of this utility model is achieved through the following technical solution: A wind farm platform turbine maintenance auxiliary device includes a first maintenance platform, a limiting frame, a first support leg, a second maintenance platform, a limiting sliding column, an upper support column, a lower support column, a strip plate, and moving wheels. The first maintenance platform has a first outer baffle on its outer side. The first support leg is connected to the lower part of the first maintenance platform, and a set of first support legs are distributed under the first maintenance platform. The upper support column is connected to the lower part of the second maintenance platform, and a set of upper support columns are distributed under the second maintenance platform. The second maintenance platform is adapted to the first outer baffle and is inserted into the first outer baffle. The second maintenance platform slides within the first outer baffle. The second maintenance platform has a second outer baffle on its side, and the second outer baffle has a baffle side plate on its side. The baffle side plates are symmetrically arranged on both sides of the second outer baffle and are in contact with the first outer baffle.

[0005] The No. 2 maintenance platform has a No. 2 inclined surface on its side, and the No. 1 maintenance platform has a No. 1 inclined surface on its side. The No. 1 inclined surface and the No. 2 inclined surface are in contact. The upper part of the lower support column has an upper insertion column. The upper insertion column is adapted to the upper support column. The upper insertion column is inserted into the upper support column and slides inside the upper support column. The lower part of the lower support column is connected to a moving wheel.

[0006] The strip plate has a side positioning rod on its side. A set of side positioning rods are distributed on the side of the strip plate. The side positioning rods are inserted into the upper support column and the upper insertion column in sequence. The limiting sliding column is connected to the baffle side plate. The limiting sliding column side plate has a sliding column side plate. The first outer baffle has a horizontal sliding hole. The side of the horizontal sliding hole has an inclined sliding hole. Beneficial effects

[0007] 1. In this utility model, the No. 2 maintenance platform is inserted into the No. 1 outer baffle, so that the No. 1 maintenance platform is assembled with it. The No. 1 inclined surface and the No. 2 inclined surface are in contact, making them an inclined surface assembly. This assembly method facilitates pushing the No. 2 maintenance platform to the lower surface of the No. 1 maintenance platform. The No. 1 support leg supports the No. 1 maintenance platform at the lower part. The upper insert is inserted into the upper support column, so that the upper support column and the lower support column are connected. The lower part of the lower support column is connected to the moving wheel. The upper support column, the lower support column, and the moving wheel form a moving support leg. This set of support legs supports the No. 2 maintenance platform and facilitates movement when pushing the No. 2 maintenance platform to the lower part of the No. 1 maintenance platform. The side positioning rods are inserted sequentially into the upper... The support column and upper insertion column are used to position the outriggers via side positioning rods, ensuring that the length of the outriggers is the same as that of the first outrigger, aligning the lower surfaces of the first and second maintenance platforms, thus lengthening the first and second maintenance platforms. The limiting sliding column passes through the inclined sliding hole and connects to the side plate of the baffle. Two sets of symmetrically distributed limiting sliding columns limit the connection between the second and first maintenance platforms, ensuring their connection status. The sliding displacement of the limiting sliding column in the horizontal sliding hole is the folded length of the second and first maintenance platforms. The vertical displacement between the horizontal and inclined sliding holes is the thickness of the first maintenance platform, so that when the second maintenance platform is placed below the first maintenance platform, the limiting sliding column slides from the inclined sliding hole into the horizontal sliding hole.

[0008] 2. When the No. 2 maintenance platform needs to be retracted under the No. 1 maintenance platform, the side positioning rod needs to be pulled out from the upper support column and the upper insertion column so that the upper surface of the lower support column is in contact with the lower surface of the upper support column. This ensures that when the No. 2 maintenance platform is under the No. 1 maintenance platform, the length of the moving leg is the same as the length of the No. 1 support leg, so that the entire device is kept horizontal. The No. 2 outer baffle works with the No. 1 outer baffle to protect the maintenance components on the No. 1 and No. 2 maintenance platforms. The device is designed to be expandable and retractable. During use, the No. 2 maintenance platform can be pushed to reduce the usable area, and larger components of the unit can be clamped to ensure the stability of the maintenance. This foldable and retractable design significantly saves storage and idle space. When stored, the second maintenance bench can be tucked under the first maintenance bench, with the overall footprint being only about the size of a single maintenance bench. This makes it suitable for maintenance scenarios with limited space, such as engine rooms and workshops. When unfolded and assembled, the work surface can be quickly extended without the need for additional equipment. It can expand the operating space within a fixed area, avoiding obstruction of the maintenance process due to limited space. The assembly and folding operations require no complicated tools; simply inserting or removing the side positioning rods and pushing the maintenance bench completes the form change. A single person can operate it quickly, saving labor and time costs. Attached Figure Description

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A wind farm platform turbine maintenance auxiliary device includes a first maintenance platform 01, a limiting frame 06, a first support leg 09, a second maintenance platform 10, a limiting sliding column 14, an upper support column 16, a lower support column 17, a strip plate 19, and moving wheels 21. The first maintenance platform 01 has a first outer baffle 02 on its outer side. The first support leg 09 is connected to the lower part of the first maintenance platform 01. A set of first support legs 09 are distributed under the first maintenance platform 01, supporting the first maintenance platform 01 at its lower part. The second maintenance platform 10 is located at its lower part. Connect the upper support column 16. A set of upper support columns 16 are distributed in the lower part of the second maintenance platform 10. The second maintenance platform 10 is adapted to the first outer baffle 02. The second maintenance platform 10 is inserted into the first outer baffle 02. The second maintenance platform 10 slides in the first outer baffle 02, so that the first maintenance platform 01 is assembled together. The second maintenance platform 10 has a second outer baffle 12 on its side. The second outer baffle 12 has a baffle side plate 13 on its side. The baffle side plate 13 is symmetrically arranged on both sides of the second outer baffle 12. The baffle side plate 13 is in contact with the first outer baffle 02.

[0016] Example 2: The second maintenance platform 10 of this utility model has a second inclined surface 11 on its side, and the first maintenance platform 01 has a first inclined surface 03 on its side. The first inclined surface 03 and the second inclined surface 11 are attached to each other, making them a splicing of inclined surfaces. This splicing method facilitates pushing the second maintenance platform 10 to the lower surface of the first maintenance platform 01. The upper part of the lower support column 17 has an upper insertion column 18, which is adapted to the upper support column 16. The upper insertion column 18 is inserted into the upper support column 16, so that the upper support column 16 and the lower support column 17 are connected. The upper insertion column 18 slides in the upper support column 16. The lower part of the lower support column 17 is connected to a moving wheel 21. The upper support column 16, the lower support column 17, and the moving wheel 21 form a moving support leg. A set of support legs supports the second maintenance platform 10 and makes it easier to move the second maintenance platform 10 to the lower part of the first maintenance platform 01.

[0017] Example 3: The strip plate 19 of this utility model has a side positioning rod 20 on its side. A set of side positioning rods 20 are distributed on the side of the strip plate 19. The side positioning rods 20 are inserted into the upper support column 16 and the upper insertion column 18 in sequence. The support leg is positioned by the side positioning rods 20 to ensure that the length of the support leg is the same as the length of the first support leg 09, so that the lower surfaces of the first maintenance platform 01 and the second maintenance platform 10 are aligned, and the first maintenance platform 01 and the second maintenance platform 10 are lengthened. The limiting slide column 14 is connected to the baffle side plate 13. The side of the limiting slide column 14 has a slide column side plate 15. The first outer baffle 02 has a horizontal sliding hole 04. The side of the horizontal sliding hole 04 has an inclined sliding hole 05.

[0018] Example 4: The limiting slide post 14 of this utility model is adapted to the horizontal sliding hole 04. The limiting slide post 14 is inserted into the horizontal sliding hole 04 and slides within the horizontal sliding hole 04. The connection between the second maintenance platform 10 and the first maintenance platform 01 is limited by two symmetrically distributed sets of limiting slide posts 14, ensuring the connection status of the two. The sliding displacement of the limiting slide post 14 within the horizontal sliding hole 04 is the folded length of the second maintenance platform 10 and the first maintenance platform 01. The vertical displacement between the horizontal sliding hole 04 and the inclined sliding hole 05 is equal to the thickness of the first maintenance platform 01. When the second maintenance platform 10 is placed below the first maintenance platform 01, the limiting sliding column 14 slides from the inclined sliding hole 05 into the horizontal sliding hole 04. The sliding column side plate 15 is in contact with the outer side of the first outer baffle 02. The side of the limiting frame 06 is in contact with the first outer baffle 02. The U-shaped buckle 07 is fastened to the limiting frame 06. The U-shaped buckle 07 is connected to the first outer baffle 02. The baffle 02 and the limiting frame 06 slide within the U-shaped buckle 07. The limiting frame 06 has a set of limiting frame side plates 08 on its side. The side of the sliding column side plate 15 is in contact with the limiting frame side plate 08. When the second maintenance platform 10 needs to be retracted under the first maintenance platform 01, the side positioning rod 20 needs to be pulled out from the upper support column 16 and the upper insertion column 18 so that the upper surface of the lower support column 17 is in contact with the lower surface of the upper support column 16. This ensures that when the second maintenance platform 10 is under the first maintenance platform 01, the length of the moving leg is the same as the length of the first support leg 09, so that the entire device is kept horizontal. The second outer baffle 12 works with the first outer baffle 02 to protect the maintenance components on the first maintenance platform 01 and the second maintenance platform 10. The device is designed to be expandable and retractable. During use, the second maintenance platform 10 can be pushed to reduce the usable area, and larger components for unit maintenance can be clamped to ensure the stability of maintenance. This foldable and retractable design significantly saves storage and idle space. When stored, the No. 2 maintenance platform 10 is tucked under the No. 1 maintenance platform 01, and the overall footprint is only about the size of a single maintenance platform. It is suitable for maintenance scenarios with limited space, such as engine rooms and workshops. When unfolded and assembled, the platform can be quickly extended without the need to assemble other equipment. It can expand the operating space within a fixed area, avoiding obstruction of the maintenance process due to limited space. The assembly and folding operations do not require complicated tools. Simply plugging and unplugging the side positioning rod 20 and pushing the maintenance platform can complete the form change. A single person can operate it quickly, saving manpower and time costs.

[0019] Example 5: The installation steps of this utility model are as follows: First, connect the lower part of the lower support column 17 to the moving wheel 21, insert the upper insertion column 18 into the upper support column 16, connect the upper part of the upper support column 16 to the second maintenance platform 10, connect the upper part of the first support leg 09 to the first maintenance platform 01, insert the second maintenance platform 10 into the first outer baffle 02, so that the first inclined surface 03 and the second inclined surface 11 are in contact, the limiting sliding column 14 passes through the horizontal sliding hole 04 and connects to the side plate of the baffle 13, and fasten the U-shaped buckle 07 on the limiting frame 06. The U-shaped buckle 07 is connected to the first outer baffle 02.

[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
