Description

Technical Field

[0001] This invention relates to the structure of a wind turbine gearbox, specifically a universal unpacking tooling for replacing components on a wind turbine gearbox tower. Background Technology

[0002] Due to its advantages such as being pollution-free and having low construction costs, wind power generation has experienced rapid development in recent years.

[0003] The gearbox is a critical component of a wind turbine generator set, and the efficiency of its assembly and disassembly / installation during maintenance is of paramount importance.

[0004] Unpacking tooling for replacing components on wind turbine gearbox towers: The existing technical solution is a traditional steel welded assembly unpacking fixture, which has the following disadvantages: Each component is formed by fixing and welding multiple steel plates, stiffening plates, and H-beams. Each component is heavy, and the entire unpacking tooling is extremely heavy. Handling it is time-consuming and labor-intensive, which affects work efficiency. The limited compatibility with single turbine models, with traditional unpacking kits corresponding to a single turbine model, significantly increases operation and maintenance costs in the current diverse wind power market.

[0005] The existing technical solution, Technology 2, uses traditional aluminum welding assembly unpacking tooling, which has the following disadvantages: 1. Aluminum alloys lack rigidity, are prone to deformation under load, and are susceptible to cracking and detachment at welded joints, posing significant safety hazards. 2. The welded shape is not adjustable, resulting in poor machine compatibility. Summary of the Invention

[0006] This invention provides a universal unpacking tooling for replacing components on wind turbine gearbox towers. Its purpose is to overcome the shortcomings of the prior art and provide a universal unpacking tooling that improves service efficiency and model compatibility while ensuring safety and service quality.

[0007] The technical solution adopted by this invention to solve its technical problem is: A universal unpacking tooling for replacing components on a wind turbine gearbox tower, characterized in that: It has four combined columns distributed at the four corners, two of which are combined columns on the blade side connected to the nacelle elastic support seat, and two of which are combined columns on the motor side connected to the frame. The modular column includes two or more fixing plates. Each fixing plate has several mounting through holes. The screw passes through the corresponding mounting through holes of the adjacent fixing plates and is combined with the nut to fix the adjacent fixing plates. It has two axial long crossbeams. The two ends of each axial long crossbeam are mounted on the fixing plate of the combined column on the opposite blade side and the fixing plate of the combined column on the motor side. After the bolts pass through the mounting through holes of the axial long crossbeam and the mounting through holes of the fixing plate, they are engaged with nuts to fix the axial long crossbeam to the fixing plate. The fixing plate connected to the axial long crossbeam is located below the uppermost fixing plate. It has two axial short crossbeams. The two ends of each axial short crossbeam are mounted on the fixing plate of the combined column on the opposite blade side and the fixing plate of the combined column on the motor side. After the bolts pass through the mounting through holes of the axial short crossbeams and the mounting through holes of the fixing plate, they are engaged with nuts to fix the axial short crossbeams to the fixing plates. The fixing plate connected to the axial short crossbeams is the uppermost fixing plate. It has two fixed radial beams perpendicular to the axial short crossbeams. The two ends of the fixed radial beams are mounted on the axial short crossbeams on both sides. The connecting plate is located below the axial short crossbeams. The square U-bolts are fastened to the fixed radial beams with their openings facing down. The two legs of the square U-bolts pass through the through holes of the connecting plate and lock with the bolts, thereby fixing and connecting the axial short crossbeams and the fixed radial beams. It has a movable radial beam perpendicular to the axial short crossbeam. Each movable radial beam is mounted on two I-beam trolleys at both ends. Square U-bolts with their openings facing down are fastened to the movable radial beams. The two legs of the square U-bolts pass through the through holes of the I-beam trolleys and lock with the bolts, thereby fixing the movable radial beams and I-beam trolleys. The two I-beam trolleys are respectively installed on the axial short crossbeams on both sides.

[0008] There are two or more axially long crossbeams.

[0009] It has an extended nut, with adjacent screws threaded to both ends of the extended nut.

[0010] There are two movable radial beams.

[0011] The I-beam pulley is mounted on the top plate at the top of the axial short crossbeam.

[0012] The advantages of this invention are: 1. By assembling multiple conventional small-sized workpieces into a large-sized unpacking tooling, the time cost of personnel handling is effectively reduced, and the risk of mechanical injury to personnel is effectively reduced; 2. The column is composed of multiple fixing plates, screws, and extended nuts, which can be adjusted at will, improving the adaptability and versatility of different unit models; 3. The unpacking process is simplified by using trolleys and crossbeams. The columns are connected by crossbeams, ensuring stability and effectively improving service efficiency and safety.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] This invention provides a disassembly tool for the torque arm positioning pin of a wind turbine gearbox.

[0018] The invention consists of radial / axial beams, fixed plates, connecting plates, I-beam trolleys, etc., and the main components are connected by screws, extended nuts, square U-bolts.

[0019] It has four combined columns 200 distributed at the four corners. The combined columns 200 on the blade side are connected to the nacelle elastic support seat 100 (the blade side base plate 7 is set on both sides of the nacelle elastic support seat 100, and the blade side base plate 7 is connected to the nacelle elastic support seat by the original bolts to form the tooling base part), and the combined columns 200 on the motor side are connected to the frame.

[0020] The modular column 200 includes two or more fixing plates 3. Each fixing plate 3 has several mounting through holes 31. A screw extending from the blade side bottom plate 7 passes through the mounting through hole 31 of the lowest fixing plate 3 and is then combined with a nut to fix the lowest fixing plate 3. Similarly, a screw extending from the frame passes through the mounting through hole 31 of the lowest fixing plate 3 and is then combined with a nut to fix the lowest fixing plate 3. After passing through the corresponding mounting through hole 31 of the adjacent fixing plate 3, the M36 coarse thread screw 4 is combined with the nut to fix the adjacent fixing plate 3. The two ends of the extended nut 5 are screwed with the adjacent M36 coarse thread screw 4 to increase the length.

[0021] The aforementioned fixing plates 3, M36 coarse thread screws 4, and extended nuts 5 form the connecting parts. Based on the height of each wind turbine nacelle, the four combined columns on the motor side and blade side are erected by adjusting the M36 coarse thread screws 4 and extended nuts 5. The nuts are tightened to the required torque to ensure the stability of the unpacking fixture.

[0022] It has two axially long crossbeams 6, with both ends of the axially long crossbeams 6 mounted on adjacent axially mounted fixing plates 3. That is, both ends of each axially long crossbeam 6 are mounted on the fixing plates 3 of the combined column 200 on the opposite blade side and the fixing plates 3 of the combined column 300 on the motor side. After the bolts pass through the mounting through holes 31 of the axially long crossbeams 6 and the fixing plates 3, they cooperate with the nuts to fix the axially long crossbeams 6 to the fixing plates 3. The fixing plates 3 connected to the axially long crossbeams 6 are located below the uppermost fixing plate 3.

[0023] It has two axial short crossbeams 2, with both ends of the axial short crossbeams 2 mounted on adjacent fixed plates 3 in the axial direction. After the bolts pass through the mounting through holes of the axial short crossbeams 2 and the mounting through holes 31 of the fixed plates 3, they cooperate with the nuts to fix the axial short crossbeams 2 and the fixed plates 3. The fixed plates 3 connected to the axial short crossbeams 2 are the uppermost fixed plates 3.

[0024] There are two axially long crossbeams 6 and two axially short crossbeams 2.

[0025] The fixed connection of the above-mentioned combination of axial long crossbeam 6, axial short crossbeam 2, and fixing plate 3 ensures that the four combined columns 200 have no risk of axial overturning.

[0026] It has two fixed radial beams 1 perpendicular to the axial short crossbeams 2. The two ends of the fixed radial beams 1 are mounted on the axial short crossbeams 2 on both sides. The connecting plate 10 is located below the axial short crossbeams 2. The square U-bolts 8 with their openings facing down are fastened to the fixed radial beams 1. The two legs of the square U-bolts 8 pass through the through holes of the connecting plate 10 and are locked with the bolts, thereby fixing and connecting the axial short crossbeams 2 and the fixed radial beams 1, ensuring that the four combined columns 200 have no risk of axial left and right tilting.

[0027] The above establishes a basic universal unpacking tooling to ensure no risk of tipping over in the front, back, left, or right directions.

[0028] The device has two movable radial beams 11 perpendicular to the axial short crossbeams 2. Each movable radial beam 11 is mounted on two No. 10 I-beam trolleys 9 at both ends. Square U-bolts 8 with their openings facing down are fastened to the movable radial beams 11. The two legs of the square U-bolts 8 pass through the through holes of the No. 10 I-beam trolleys 9 and are locked with the bolts, thus fixing the movable radial beams 11 and the No. 10 I-beam trolleys 9 together. The two No. 10 I-beam trolleys 9 are respectively installed on the top plates 21 at the top of the axial short crossbeams 2 on both sides. Thus, the movable radial beams 11 can move back and forth along the axial short crossbeams 2, ensuring that the wind turbine gearbox can be moved towards the motor side after being opened, thus completing the component replacement.

[0029] The steps of the tooling of this invention are as follows: 1. Remove the external accessories of the wind turbine gearbox and drain the lubricating oil; 2. Two blade-side combined columns 200 are constructed using the blade-side base plate 7, M36 coarse thread screw 4, and fixing plate 3. The blade-side combined columns 200 are connected to two motor-side combined columns 200. The blade-side combined columns 200 are connected to the nacelle elastic support seat 100, and the motor-side combined columns 200 are connected to the frame.

[0030] 3. Assemble the two axial long crossbeams 6, the two axial short crossbeams 2, and the fixed radial crossbeam 1 to the positions of each modular column 200 to complete the initial shape of the unpacking tooling.

[0031] 4. The radial crossbeam 11 and the No. 10 I-beam trolley 9 are connected and assembled to the axial short crossbeam 2 to achieve axial translation after the box is opened.

[0032] Remove the gearbox connecting bolts, install the slings and hand chain hoist to connect with the moving radial beam 11 of the unpacking fixture, and gradually complete the unpacking and component replacement.
