Description

Technical Field

[0001] This invention relates to the field of wind turbines, and more particularly to a quick-loading and unloading mounting frame for transporting wind turbine blades. Background Technology

[0002] Strong winds are prevalent at wind turbine installation sites year-round. Especially after the tower installation, the turbine main unit and blades need to be installed quickly; otherwise, the completed tower poses a significant risk of tipping over. During tower installation, the blades need to be assembled and transported in the factory using mounting frames, universal joint installation equipment, and transport trucks. Upon arrival at the wind turbine site, the blades need to be hoisted and disassembled. Controlling the truck's transport speed is difficult during this process, and the loading and unloading speed of the turbine blades on the transport trucks is crucial to the successful installation of the blades. Currently… The traditional method of installing wind turbine blades on mounting brackets involves hoisting. Because the gap between the blade flange bolts and the bolt holes of the traditional blade mounting bracket is small, precise control of the blade installation and removal angle is required. Otherwise, the blade flange bolts will get stuck in the bolt holes of the traditional blade mounting bracket, making installation and removal difficult and easily damaging the blade flange bolts. Therefore, it takes a long time to adjust the blade removal angle. Furthermore, the process of tightening and loosening the blade flange bolts requires manual operation, which consumes a lot of manpower and time, making it difficult to quickly load and unload wind turbine blades from trucks.

[0003] Based on the above-mentioned shortcomings, there is an urgent need to design a quick loading and unloading fixing frame for wind turbine blade transportation to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a quick loading and unloading fixing frame for transporting wind turbine blades. By using a combination of limiting device, surrounding device, tightening device, driving device, linkage component, inflation device and protective component, wind turbine blades can be quickly loaded and unloaded before and after transportation, improving the installation speed of wind turbine blades and protecting the blades from damage during transportation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including an external flange, wherein the external flange is provided with a limiting device, a surrounding device, a tightening device and a driving device;

[0006] An installation pipe is fixedly connected to one side of the external flange. The installation pipe has a hole on the side away from the external flange. An inner pipe is fixedly connected to the other side of the installation pipe. The inner pipe has a hole. A support frame is fixedly connected to the installation pipe near the external flange. A double-layer frame is fixedly connected to the other side of the support frame. An outer pipe with a hole is fixedly connected to the double-layer frame on the side away from the support frame.

[0007] A limiting device is provided between the two layers of the frame;

[0008] A surrounding device is provided at the position near the outer tube between the two layers of the frame and at the opening structure of the mounting tube. The surrounding device is used to surround the bolts of the blade flange, and the limiting device is used to limit the position of the surrounding device.

[0009] A tightening device is provided near the support frame of the limiting device, and the tightening device is used to fix the bolts of the blade flange to the surrounding device.

[0010] The tightening device is provided with a driving device, which is used to drive the tightening device.

[0011] As a further improvement of the present invention, the limiting device includes electric slip rings, which are respectively installed on the outer layer between the double-layer frames. Limiting frames are fixedly connected between the electric slip rings, and limiting rings are fixedly connected between the limiting frames. A positioning frame is fixedly connected between the double-layer frames near the side of the surrounding device.

[0012] As a further improvement of the present invention, the enclosure device includes a first movable pair, which is fixedly connected in an array between the double-layer frame near the outer tube. Each movable part of the first movable pair is fixedly connected to a clamping frame. A second movable pair is fixedly connected in an array near the first movable pair at the opening structure of the mounting tube. The number of the second movable pairs is the same as the number of the first movable pairs. Both the first and second movable pairs have damping properties. Each movable part of the second movable pair is fixedly connected to a top support frame. The clamping frame and the top support frame are provided with openings of equal radius at opposite positions. The corresponding clamping frame and the top support frame cooperate with each other.

[0013] As a further improvement of the present invention, the tightening device includes an extension frame, which is fixedly connected to both sides of the limiting frame near the external flange. A third sliding pair is fixedly connected to each extension frame. An elastic element, which is a straight spring, is provided at each of the third sliding pairs. An mounting ring is fixedly connected between the sliding parts of the third sliding pair. An internally threaded sleeve is rotatably connected to the mounting ring in an array. The driving device is located at the mounting ring near the external flange and is connected to the internally threaded sleeve.

[0014] As a further improvement of the present invention, the driving device includes an electric annular slide rail, which is fixedly connected to the mounting ring near the external flange. A toothed ring is fixedly connected between the moving parts of the electric annular slide rail, and a gear is fixedly connected to the internal threaded sleeve near the toothed ring. The gear engages with the toothed ring.

[0015] As a further improvement of the present invention, a linkage component is also included. The linkage component is disposed between the limiting frame, the first movable pair and the second movable pair. The linkage component is used to enable the clamping frame and the top support frame to work automatically. The outer and inner circumferences of the limiting frame are rotatably connected with guide wheels in an array. The guide wheels correspond to the positions of the first movable pair and the second movable pair. The first movable pair and the second movable pair are fixedly connected with guide rails at positions near the guide wheels. The guide wheels cooperate with the adjacent guide rails respectively.

[0016] As a further improvement of the present invention, an inflation device is also included, which is disposed at the outer tube and the inner tube. The inflation device is used to protect the flange wall of the wind turbine blade from damage caused by shaking during transportation. Airbags are fixedly connected to the opening structure of the inner tube and the outer tube. The airbags located at the outer tube face the inner circle and are connected to each other by an exchange pipe. The airbags located at the inner tube face the outer circle and are connected to each other by an exchange pipe. Air pumps are fixedly connected to the outer periphery of the outer tube and the inner periphery of the inner tube. The air pumps are respectively connected to the adjacent exchange pipes.

[0017] As a further improvement of the present invention, a protective component is also included. The protective component is located on the side of the outer tube away from the external flange. The protective component is used to guide the blade flange cylinder wall when it is removed from the inner tube and the outer tube, so as to avoid damage caused by the blade flange cylinder wall rubbing against the inner wall of the outer tube during removal. A fixing ring is fixedly connected to the side of the outer tube away from the external flange, and a protective wheel set is installed in an array on the inner circumference of the fixing ring.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention uses a blade flange cylinder wall that directly passes between the outer and inner tubes for initial positioning and fixation. Then, a surrounding device clamps and fixes the blade flange bolts, and a limiting device fixes and detaches the surrounding device. This ensures that the blade flange is not affected by the precise positioning of its flange bolts when assembling and removing the quick-loading and unloading mounting bracket used for wind turbine blade transportation. This avoids the time-consuming process caused by the flange bolts being difficult to enter the bolt holes of traditional mounting brackets. At the same time, it protects the threads of the blade flange bolts from damage due to hard friction. Furthermore, through the driving device and the tightening device, the blade flange bolts can be quickly fixed and detached, achieving the purpose of rapid blade loading and unloading.

[0020] 2. By increasing or decreasing the gap between the clamping frame and the top support frame, this invention allows the blades to be quickly detached from the blade flange bolts without precisely aligning the blade's retraction angle when they are loaded and unloaded onto the quick-release mounting frame used for wind turbine blade transportation, thus preventing damage to the blade flange bolts.

[0021] 3. By using a starting drive device to rotate the internal threaded sleeve, the present invention enables the internal threaded sleeve to fix the fan flange bolts to the clamping frame and the top support frame. This allows for the rapid tightening and loosening of the blade flange bolts from the clamping frame and the top support frame, thereby quickly completing the installation and removal of the fan blades.

[0022] 4. The present invention uses a method of placing the flange wall of the blade between airbags, which protects the flange wall of the wind turbine blade from damage caused by shaking during transportation. Attached Figure Description

Detailed Implementation

[0045] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0046] Example 1

[0047] like Figure 1-10 As shown, a quick-loading and unloading fixing frame for transporting wind turbine blades includes an outer flange 1, a mounting pipe 2, an inner pipe 3, a support frame 4, a double-layer frame 5, an outer pipe 6, a limiting device 7, a surrounding device 8, a tightening device 9, and a driving device 10. The mounting pipe 2 is fixedly connected to one side of the outer flange 1, and the mounting pipe 2 has a hole on the side away from the outer flange 1. The inner pipe 3 is fixedly connected to the other side of the mounting pipe 2, and the inner pipe 3 also has a hole. The support frame 4 is fixedly connected to the mounting pipe 2 near the outer flange 1. The double-layer frame 5 is fixedly connected to the other side of the support frame 4, and the double-layer frame 5 is located away from the support frame. An outer tube 6 is fixedly connected to one side of the support frame 4. The outer tube 6 has a perforated structure. A limiting device 7 is provided between the double-layer frame 5. A surrounding device 8 is provided between the double-layer frame 5 near the outer tube 6 and at the opening structure of the mounting tube 2. The surrounding device 8 is used to surround the bolts of the blade flange. The limiting device 7 is used to limit the position of the surrounding device 8. A tightening device 9 is provided near the supporting frame 4 of the limiting device 7. The tightening device 9 is used to fix the bolts of the blade flange to the surrounding device 8. A driving device 10 is provided at the tightening device 9. The driving device 10 is used to drive the tightening device 9.

[0048] When wind turbine blades need to be transferred from the factory to the wind turbine construction site, this quick-loading and unloading mounting frame for wind turbine blade transportation can be used. This frame can be installed on the universal mounting equipment on the transport truck via the external flange 1. After adjusting the orientation of the universal mounting equipment, the blade flange cylinder wall can be hoisted and moved between the outer tube 6 and the inner frame. The bolts of the blade flange are close to the surrounding device 8. At this time, the surrounding device 8 can be pushed to surround and fix the bolts of the blade flange, and the limiting device 7 can be controlled to work. The limiting device 7 will move to the left to fix the surrounding device 8, thereby restricting the position of the surrounding device 8 and clamping the bolts of the blade flange. During the leftward movement of the limiting device 7, it will drive the tightening device 9 and the driving device 10 to move to the left. After the limiting device 7 is in place, the tightening device 9 will be under force, and then it can be started. The driving device 10 drives the tightening device 9 to work. Under stress, the tightening device 9 fixes the bolts of the blade flange to the surrounding device 8, thereby fixing the blade to the quick-loading and unloading frame for wind turbine blade transportation. When it is necessary to remove the blade from the quick-loading and unloading frame for wind turbine blade transportation, the above steps can be reversed. In this way, by clamping and fixing the flange bolts with the surrounding device 8 and fixing and unloading the surrounding device 8 with the limiting device 7, the blade flange is not affected by the need for precise positioning of its flange bolts when assembling and removing it from the quick-loading and unloading frame for wind turbine blade transportation. This avoids the time-consuming process caused by the flange bolts being difficult to enter the bolt holes of the traditional frame, and protects the threads of the blade flange bolts from damage due to hard friction. Furthermore, the driving device 10 and the tightening device 9 enable the blade flange bolts to be quickly fixed and detached, achieving the purpose of quick blade loading and unloading.

[0049] By using the blade flange cylinder wall to directly pass between the outer and inner tubes for initial positioning and fixation, and then using the surrounding device to clamp and fix the blade flange bolts, and the limiting device to fix and detach the surrounding device, the blade flange can be assembled and removed from the quick-loading and unloading mounting bracket used for wind turbine blade transportation without being affected by the need for precise positioning of its flange bolts. This avoids the time-consuming process caused by the flange bolts being difficult to enter the bolt holes of traditional mounting brackets, and at the same time protects the threads of the blade flange bolts from damage due to hard friction. Furthermore, through the driving device and the tightening device, the blade flange bolts can be quickly fixed and detached, achieving the purpose of rapid blade loading and unloading.

[0050] Example 2

[0051] like Figure 7-15 and Figure 21As shown, the limiting device 7 includes an electric slip ring 71, a limiting frame 72, a limiting ring 73, and a positioning frame 74. The electric slip rings 71 are respectively installed on the outer layer between the double-layer frames 5. The limiting frame 72 is fixedly connected between the electric slip rings 71. The limiting ring 73 is fixedly connected between the limiting frames 72. The positioning frame 74 is fixedly connected to the double-layer frames 5 near the side of the surrounding device 8.

[0052] When the enclosing device 8 clamps the blade flange bolts, the electric slip ring 71 is activated. The electric slip ring 71 drives the limiting frame 72 and the limiting ring 73 to move to the left, so that the limiting frame 72 fixes the position of the outer periphery of the enclosing device 8 located at the double-layer frame 5, and the limiting ring 73 fixes the position of the inner ring of the enclosing device 8 located at the mounting pipe 2. In this way, the blade flange bolts can be quickly fixed by the enclosing device 8. After the limiting frame 72 fixes the position of the enclosing device 8, the positioning frame 74 will further fix the position of the limiting frame 72 to ensure that the limiting frame 72 will not shift its position and to avoid the bolts bending due to the shaking of the wind turbine blades during the transfer process. When disassembling the blades, the electric slip ring 71 can be controlled to run in reverse, so that the limiting frame 72 and the limiting ring 73 move to the right and disengage from fixing the position of the enclosing device 8.

[0053] By increasing or decreasing the gap between the clamping frame and the top support frame, the blades can be quickly detached from the blade flange bolts without precisely aligning the blade's retraction angle when being loaded and unloaded onto the quick-release mounting frame used for wind turbine blade transportation, thus preventing damage to the blade flange bolts.

[0054] like Figure 7-10 , Figure 15 and Figure 17-20 As shown, the enclosure device 8 includes a first movable pair 81, a clamping frame 82, a second movable pair 83, and a top support frame 84. The first movable pair 81 is fixedly connected in an array to the double-layer frame 5 near the outer tube 6. The moving parts of the first movable pair 81 are all fixedly connected to the clamping frame 82. The opening structure of the mounting tube 2 is fixedly connected in an array to the side of the first movable pair 81. The number of the second movable pairs 83 is the same as the number of the first movable pairs 81. Both the first movable pair 81 and the second movable pair 83 have damping properties. The moving parts of the second movable pair 83 are all fixedly connected to the top support frame 84. The clamping frame 82 and the top support frame 84 are provided with openings of equal radius at opposite positions. The corresponding clamping frame 82 and the top support frame 84 cooperate with each other.

[0055] The first movable joint 81 and the second movable joint 83 push the clamping frame 82 and the top support frame 84, increasing the gap between them. This allows the blade flange bolts to be inserted between the clamping frame 82 and the top support frame 84 without obstruction, and eliminates the need for precise pre-positioning to pass through the bolt holes of traditional blade mounting brackets. This improves the speed of blade flange installation on the quick-release mounting bracket used for wind turbine blade transportation. When the blade flange bolts are in the position between the clamping frame 82 and the top support frame 84, external rotation of the blade flange itself pushes the clamping frame 82 and the top support frame 84 towards each other, causing them to contact and engage, thus ensuring proper clamping and bolt insertion. The opening structure of the clamping frame 82 and the top support frame 84 clamps and fixes the blade flange bolts, thus completing the clamping and fixing of the blade flange bolts. When it is necessary to disassemble the blade, the operation can be reversed as described above to increase the gap between the clamping frame 82 and the top support frame 84. This allows the blade to be lifted and removed from the quick-release mounting frame used for wind turbine blade transportation without the need for precise alignment of the blade's removal angle. This is because when fixing blades with traditional blade mounting frames, the gap between the blade flange bolts and the bolt holes of the traditional blade mounting frame is small, requiring precise control of the blade's removal angle. Otherwise, the blade flange bolts will get stuck in the bolt holes of the traditional blade mounting frame, making it difficult to disassemble and easily damaging the blade flange bolts. Therefore, it takes a long time to adjust the blade's removal angle.

[0056] like Figure 7-10 , Figure 13-14 and Figure 16 As shown, the tightening device 9 includes an extension frame 91, a third sliding pair 92, an elastic element 93, a mounting ring 94, and an internally threaded sleeve 95. The extension frame 91 is fixedly connected to both sides of the limiting frame 72 near the external flange 1. The extension frame 91 is fixedly connected to the third sliding pair 92. The third sliding pair 92 is provided with an elastic element 93, which is a straight spring. The moving parts of the third sliding pair 92 are fixedly connected to the mounting ring 94. The mounting ring 94 is rotatably connected to the internally threaded sleeve 95 in an array. The driving device 10 is located on the mounting ring 94 near the external flange 1 and is connected to the internally threaded sleeve 95.

[0057] When the limiting frame 72 moves to the left, it will drive the extension frame 91 to move to the left, thereby driving the mounting ring 94 and the internal threaded sleeve 95 to move to the left. During this leftward movement, the internal threaded sleeve 95 will contact the fan flange bolts, stopping its leftward movement. At this time, the third moving pair 92 will continue to move to the left via the elastic element 93, causing the elastic element 93 to enter a stressed state, thus giving the internal threaded sleeve 95 a tendency to move to the left. The power source is then activated; the drive device 10 will rotate the internal threaded sleeve 95, thereby fixing the fan flange bolts to the clamping frame 82 and the top support frame 84, thus completing the fixing of the fan blades; when disassembling the fan, the drive device 10 can be operated in reverse as described above to remove the internal threaded sleeve 95 from the blade flange bolts; in this way, the bolts of the blade flange can be quickly tightened and removed from the clamping frame 82 and the top support frame 84.

[0058] like Figure 7-10 , Figure 13-14 and Figure 16 As shown, the driving device 10 includes an electric circular slide rail 101, a gear ring 102, and a gear 103. The electric circular slide rail 101 is fixedly connected to the mounting ring 94 near the external flange 1. The gear ring 102 is fixedly connected between the moving parts of the electric circular slide rail 101. The gear 103 is fixedly connected to the internal threaded sleeve 95 near the gear ring 102. The gear 103 cooperates with the gear ring 102.

[0059] The electric annular slide rail 101 can be activated, and the electric annular slide rail 101 will drive the gear 103 to rotate through the gear ring 102, thereby driving the internal threaded sleeve 95 to rotate.

[0060] By using a starting drive device to rotate the internal threaded sleeve, the internal threaded sleeve can fix the wind turbine flange bolts to the clamping frame and the top support frame. This allows for quick tightening and loosening of the blade flange bolts from the clamping frame and the top support frame, thus enabling rapid installation and removal of the wind turbine blades.

[0061] Example 3

[0062] like Figure 7-15 , Figure 16-17 and Figure 21As shown, it also includes a linkage component 11, which includes guide wheels 111 and guide rails 112. The linkage component 11 is disposed between the limiting frame 72, the first moving pair 81, and the second moving pair 83. The linkage component 11 is used to enable the pressing frame 82 and the top support frame 84 to work automatically. The outer and inner circumferences of the limiting frame 72 are rotatably connected with guide wheels 111 in an array. The guide wheels 111 correspond to the positions of the first moving pair 81 and the second moving pair 83. The first moving pair 81 and the second moving pair 83 are fixedly connected to the guide rails 112 near the guide wheels 111. The guide wheels 111 cooperate with the adjacent guide rails 112 respectively.

[0063] When the limiting frame 72 moves to the left, it will drive the guide wheel 111 to move to the left. The guide wheel 111 will automatically drive the first moving pair 81 and the second moving pair 83 to move through the guide rail 112, thereby closing the clamping frame 82 and expanding the top support frame 84, so that the clamping frame 82 and the top support frame 84 automatically clamp and fix the blade flange bolts. When the limiting frame 72 moves to the right, the guide wheel 111 will automatically drive the top support frame 84 and the clamping frame 82 to reset through the guide rail 112. In this way, the automation and speed of loading and unloading blades onto the quick loading and unloading fixing frame for wind turbine blade transportation can be further improved.

[0064] like Figure 5-6 As shown, it also includes an inflation device 12, which includes an airbag 121, an exchange pipe 122, and an air pump 123. The inflation device 12 is located at the outer tube 6 and the inner tube 3. The inflation device 12 is used to protect the flange wall of the wind turbine blades from damage caused by shaking during transportation. An airbag 121 is fixedly connected to the opening structure of both the inner tube 3 and the outer tube 6. The airbags 121 located at the outer tube 6 all face the inner circle and are connected to each other by the exchange pipe 122. The airbags 121 located at the inner tube 3 all face the outer circle and are connected to each other by the exchange pipe 122. An air pump 123 is fixedly connected to the outer periphery of the outer tube 6 and the inner periphery of the inner tube 3. The air pump 123 is connected to the adjacent exchange pipe 122 respectively.

[0065] When the blade flange wall is placed between the inner tube 3 and the outer tube 6, the air pump 123 can be started. The air pump 123 will inflate the air bag 121, which will protect the flange wall of the wind turbine blade from damage caused by shaking during transportation. When it is necessary to disassemble the blade, the air bag 121 can be deflated.

[0066] By placing the blade flange wall between the airbags, the airbags will protect the flange wall of the wind turbine blade from damage caused by shaking during transportation.

[0067] like Figure 5 As shown, it also includes a protective component 13, which includes a fixing ring 131 and a protective wheel assembly 132. The protective component 13 is located on the side of the outer tube 6 away from the external flange 1. The protective component 13 is used to guide the blade flange cylinder wall when it is removed from the inner tube 3 and the outer tube 6, so as to avoid the blade flange cylinder wall from rubbing against the inner wall of the outer tube 6 and causing damage. The fixing ring 131 is fixedly connected to the side of the outer tube 6 away from the external flange 1, and the protective wheel assembly 132 is installed in an array on the inner circumference of the fixing ring 131.

[0068] When the blade flange cylinder wall is removed from the outer tube 6, the protective wheel assembly 132 can prevent the blade flange cylinder wall from directly rubbing against the inner wall of the outer tube 6 and causing damage.

[0069] By using a combination of limiting devices, surrounding devices, tightening devices, driving devices, linkage components, inflation devices, and protective components, wind turbine blades can be quickly loaded and unloaded before and after transportation, improving the installation speed of wind turbine blades and protecting the blades from damage during transportation.

[0070] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
