Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade transportation and fixing technology, and more specifically, it relates to a wind turbine blade transportation and fixing seat with locking function. Background Technology

[0002] In existing technologies, wind turbine blade transport mounting brackets are key devices in the field of wind power equipment transportation. They are mainly used to ensure the safe and stable transport of uniquely shaped and large wind turbine blades during long-distance transportation. Current technologies typically require fixing the root of the wind turbine blade to one end of a mounting flange to prevent loosening or displacement due to external forces such as bumps in complex transportation environments. However, in practical applications, the installation and disassembly of the mounting flange is usually quite cumbersome, requiring the use of various specialized tools such as wrenches, sockets, and hydraulic tools. The entire process is not only time-consuming and labor-intensive but also requires professional technicians, significantly increasing loading and unloading time and labor costs. Furthermore, due to the complexity of the mounting and disassembly process, convenient replacement of the mounting flange is not possible. This makes it difficult to flexibly change the mounting flange specifications according to the specific size and shape of the blade root when dealing with wind turbine blades of different specifications and models. This severely restricts the versatility and adaptability of the transport equipment, reduces transportation efficiency, and increases enterprise operating costs.

[0003] Furthermore, while some improved wind turbine blade fixing devices on the market have achieved convenient assembly and disassembly of the fixing flange through optimized connection mechanisms and quick-release structures, thereby improving the ease of flange replacement to some extent, these devices generally suffer from simple structures and crude designs, resulting in insufficient overall stability and reliability. Specifically, these simple connection mechanisms often lack effective locking devices and anti-loosening designs. In the special environment of long-distance wind turbine blade transportation, they face complex road conditions such as bumpy roads, sharp turns, uphill and downhill sections, as well as sudden situations such as braking, stopping, and emergency avoidance. Due to the combined effects of various stress factors such as vibration, impact, and centrifugal force, the fixing structure is prone to gradually loosening or even completely falling off. Once the fixing structure fails, it will not only damage the expensive wind turbine blades, but may also cause serious traffic safety accidents, endangering the lives and property of transportation personnel and other road users, and even affecting the construction progress and economic benefits of the entire wind power project, resulting in incalculable economic losses and social impacts.

An adapter slot 23 is opened on the side wall of the adapter sleeve 11.

[0029] A fixed seat 24 is provided below the fixed flange 1. A mounting seat 25 is rotatably connected to one side of the fixed seat 24 via a rotating shaft. Sliding grooves 26 are symmetrically provided on both sides of the fixed seat 24. A first motor 27 is detachably provided on one side of the fixed seat 24. A first lead screw 28 is rotatably provided inside the fixed seat 24. The output end of the first motor 27 is detachably connected to the first lead screw 28. A sliding frame 29 is detachably provided inside the fixed seat 24. The sliding frame 29 is movably connected to the first lead screw 28 via a thread. Movable plates 30 are symmetrically rotatably connected to both sides of the mounting seat 25. The sliding frame 29 slides through the sliding grooves 26 and is rotatably connected to the movable plates 30.

[0030] A mounting bracket 31 is detachably provided on one side of the mounting base 25. A cylinder 32 is detachably provided inside the mounting bracket 31. A piston rod 33 is connected to the output end of the cylinder 32. A sliding groove 34 is provided in the mounting bracket 31. A clamping bracket 35 is symmetrically provided on the mounting bracket 31. One end of the clamping bracket 35 slides into the sliding groove 34. One end of the piston rod 33 is detachably connected to one side of the clamping bracket 35.

[0031] A hydraulic cylinder 36 is detachably mounted on the mounting bracket 31. A hydraulic rod 37 is connected to the output end of the hydraulic cylinder 36. A lifting plate 38 is detachably connected to the other end of the hydraulic rod 37. A guide sleeve 39 is provided on the outside of the hydraulic cylinder 36. A guide rod 40 is slidably mounted in the guide sleeve 39. The top end of the guide rod 40 is detachably connected to the lifting plate 38.

[0032] The mounting base 25 has a sliding groove 41, in which a sliding block 42 is slidably mounted. A fixed flange 1 is mounted on one side of the sliding block 42. A second motor 43 is detachably mounted on the mounting base 25. A second lead screw 44 is rotatably mounted in the sliding groove 41. The output end of the second motor 43 is detachably connected to the top end of the second lead screw 44. The sliding block 42 is movably connected to the second lead screw 44 through a thread.

[0033] In this embodiment, when the device is needed, the mounting base 24 is first fixed on the transport vehicle. Then, the wind turbine blade is hoisted above the mounting base 24, with the root of the wind turbine blade abutting against the mounting flange 1, but not tightly. Simultaneously, the lifting plate 38 supports the wind turbine blade. Then, the two cylinders 32 are opened simultaneously. The cylinders 32 drive the piston rod 33 connected to the output end to retract, causing the piston rod 33 to drive the clamping frame 35 to slide along the slide groove 34. This causes the two clamping frames 35 to move inward simultaneously, limiting the two sides of the wind turbine blade with the inner wall of the clamping frame 35. Then, the hydraulic cylinder 36 is opened, driving the hydraulic rod 37 connected to the output end to rise. This causes the hydraulic rod 37 to push the top lifting plate 38 to rise, and the lifting plate 38 drives the guide rod 40 to slide upward along the guide sleeve 39. At the same time, the lifting plate 38 pushes the upper wind turbine blade to rise, so that the lifting plate 38 and the inner walls of the two clamping frames 35 cooperate to support the wind turbine blade. The outer wall is locked, and then the second motor 43 is turned on. The second motor 43 drives the second lead screw 44 connected to the output end to rotate. Then the sliding block 42 will drive the fixed flange 1 on one side to slide along the sliding groove 41. When the fixed flange 1 is concentrically aligned with the root of the wind turbine blade, the second motor 43 is turned off, and then the first motor 27 is driven in the forward direction. Then the first motor 27 will drive the first lead screw 28 connected to its output end to rotate in the forward direction. Since the first lead screw 28 and the sliding frame 29 are connected by threads, and the two ends of the sliding frame 29 slide through the sliding groove 26, the sliding frame 29 will slide along the sliding groove 26. Since the two ends of the movable plate 30 are rotatably connected to the sliding frame 29 and the mounting base 25 respectively, the movable plate 30 will change its angle, causing the movable plate 30 to push the mounting base 25 upward, causing the mounting base 25 to rotate along one end of the shaft, causing the mounting base 25 to tilt at an angle, lifting the rear end of the wind turbine blade, thereby facilitating the transportation of the wind turbine blade.

[0034] Please see Figure 4 and Figure 5 As a further implementation of the overall equipment: a guide block 45 is fixedly provided on the inner side of the movable sleeve 6, and a guide groove 46 is provided on the outer side of the fastening sleeve 3, with the guide block 45 sliding in the guide groove 46.

[0035] A return spring 47 is movably sleeved on the outside of the return rod 21. One end of the return spring 47 is connected to the fastening sleeve 3, and the other end of the return spring 47 abuts against one side of the mating plate 4.

[0036] A reset rod 48 is connected to one side of the reset block 7, and a reset hole 49 is provided in the fixed block 8. One end of the reset rod 48 is slidably inserted into the reset hole 49.

[0037] More specifically, when the specifications of the fixed flange 1 need to be changed according to usage requirements, firstly, the mating plate 4 is rotated forward. The mating plate 4 will drive the mating hole 5 and the reset block 7 on one side to rotate forward. Then, the reset block 7 and the fixed block 8 cooperate to press the reset spring 9, and the reset block 7 will drive the reset rod 48 on one side to rotate forward along the reset hole 49. When the reset spring 9 is pressed to its limit, the mating hole 5 just rotates to a position concentric with the return rod 21. Then, the moving sleeve 6 is pushed. The moving sleeve 6 will drive the inner guide block 45 to slide along the guide groove 46, and the moving sleeve 6 will simultaneously drive the return rod 21 on one side to slide into the return hole. At the same time, the moving sleeve 6 and the mating plate 4 cooperate to press the return spring 47, so that the moving sleeve 6 no longer restricts the outer wall of the moving plate 14. Then, the adapter 11 is rotated forward. The adapter 11 will drive the movable frame 12 on one side to rotate forward, and the movable frame 12 will drive the movable rod 13, the movable spring 15, and the movable plate 14 to rotate forward. Then, the inner wall of the movable groove 10 presses against one end of the movable rod 13. Due to the rounded corner design of the inner wall edge of the movable groove 10 and one end of the movable rod 13, one end of the movable rod 13 will slide out of the movable groove 10, and the movable rod 13 will drive the other end of the movable plate 14 to slide outward, so that the movable plate 14 drives the movable spring 15 to stretch outward. At the same time, the adapter 11 will drive the adapter groove 23 to rotate forward. When the adapter groove 23 rotates to the position corresponding to the adapter plate 17, the rotation of the adapter 11 stops. At this time, the inner wall of the adapter 11 no longer presses against the adapter plate 17. 7. The outer wall is limited, and then the fastening sleeve 3 is pulled outward. The fastening sleeve 3 will then drive the fastening block 18 and other components to move, causing the inner wall of the fastening groove 20 to press against one end of the fastening block 18. Due to the hemispherical structure design of one end of the fastening block 18 and the arc-shaped structure design of the fastening groove 20, one end of the fastening block 18 will gradually slide out of the fastening groove 20. The fastening block 18 will then drive one side of the adapter plate 17 to slide outward through the adapter groove 23, and the adapter plate 17 will drive one side of the adapter spring 22 to stretch outward. When the fastening sleeve 3 is completely removed, the adapter spring 22 resets and pulls the adapter plate 17, causing the adapter plate 17 and the adapter spring 22 to retract into the relief groove 16. The adapter plate 17 will then drive one side of the fastening block 18 to slide inward and reset, thereby achieving complete removal of the fastening sleeve 3. Remove the fastening sleeves 3 as described above, and then remove the other two fastening sleeves 3. Then, remove the fixed flange 1 from one side of the sliding block 42 and replace it. After replacement, reattach the replaced fixed flange 1 to one side of the sliding block 42, ensuring that the fastening rod 2, which is fixedly connected to one side of the fixed flange 1, slides through the pre-drilled mounting hole on the sliding block 42. Then, fit the fastening sleeve 3 onto the outside of the fastening rod 2 from the other side. The inclined structure at the outer end of the top block 19 then pushes the fastening block 18 outwards, causing the fastening block 18 to again slide the adapter plate 17 outwards. The adapter plate 17 will then again pull the adapter spring 22 outwards. When the fastening sleeve 3 is fully fitted onto the outside of the fastening rod 2, the fastening block 18 corresponds to the position of the fastening groove 20.Then, the adapter spring 22 resets and pulls the adapter plate 17, causing the adapter plate 17 to slide the fastening block 18 on one side inwards, so that one end of the fastening block 18 is reinserted into the fastening groove 20, and the adapter spring 22 causes the adapter plate 17 to slide back into the relief groove 16. At this time, the adapter 11 is rotated in the opposite direction, which will cause the adapter groove 23 and the moving frame 12 on one side to rotate in the opposite direction, so that the moving frame 12 drives the moving rod 13, the moving spring 15, and the moving plate 14 to rotate in the opposite direction. After the groove 23 is rotated and reset, the inner wall of the adapter 11 limits the outer wall of the adapter plate 17, preventing the fastening block 18 and the adapter plate 17 from moving outward. At this time, the moving frame 12 drives the moving rod 13 and other components to rotate and reset to the position corresponding to the original moving groove 10. Then, the moving spring 15 resets and pulls the moving plate 14, causing the moving plate 14 to slide the moving rod 13 inward and reset. Then, one end of the moving rod 13 will be reinserted into the original moving groove 10. Then, the moving sleeve 6 is released, and the return spring 47 pushes the moving sleeve... 6 drives the inner guide block 45 to slide and reset along the guide groove 46, and the moving sleeve 6 will drive the return rod 21 on one side to slide and reset. When the return spring 47 is fully reset, the return rod 21 is fully reset to the original side of the mating plate 4, so that the return rod 21 no longer limits the mating plate 4 through the mating hole 5. Then the reset spring 9 pushes the reset block 7 to rotate in the opposite direction to reset. Then the reset block 7 will drive the reset rod 48 on one side to rotate in the opposite direction along the reset hole 49 to reset, and the reset block 7 will drive the mating hole 5 to rotate and reset through the mating plate 4 to no longer be in contact with the return spring 47. The return rod 21 supports the moving sleeve 6 to one side of the mating plate 4. The guide block 45 and guide groove 46 limit the movement of the moving sleeve 6, preventing it from moving. The inner wall of the moving sleeve 6 then limits the outer wall of the moving plate 14, preventing the moving plate 14 and the moving rod 13 from sliding outwards. Finally, the moving rod 13 and the moving groove 10 work together to lock and position the moving frame 12, preventing accidental rotation of the moving frame 12 and the mating plate 11, thus ensuring a stable installation of the fixed flange 1.

[0038] In summary, when using or operating the overall equipment: First, fix the mounting base 24 onto the transport vehicle. Then, hoist the wind turbine blades above the mounting base 24, ensuring the root of the blades abuts against the mounting flange 1, but not tightly. Simultaneously, support the wind turbine blades with the lifting plate 38. Then, simultaneously open the two cylinders 32. The cylinders 32 drive the piston rods 33 connected to the output end to retract, causing the piston rods 33 to slide the clamping frames 35 along the slide groove 34. This causes the two clamping frames 35 to move inward simultaneously, limiting the sides of the wind turbine blades with the inner walls of the clamping frames 35. Then, open the hydraulic cylinder 36, which drives the hydraulic rod 37 connected to the output end to rise. This causes the hydraulic rod 37 to push the top lifting plate 38 upward, and the lifting plate 38 drives the guide rod 40 to slide upward along the guide sleeve 39. At the same time, the lifting plate 38 pushes the upper wind turbine blades upward, allowing the lifting plate 38 and the inner walls of the two clamping frames 35 to cooperate in supporting the wind... The outer wall of the generator blade is locked, and then the second motor 43 is turned on. The second motor 43 drives the second lead screw 44 connected to the output end to rotate. Then the sliding block 42 will drive the fixed flange 1 on one side to slide along the sliding groove 41. When the fixed flange 1 is concentrically aligned with the root of the wind turbine blade, the second motor 43 is turned off, and then the first motor 27 is driven in the forward direction. The first motor 27 will drive the first lead screw 28 connected to its output end to rotate in the forward direction. Since the first lead screw 28 and the sliding frame 29 are connected by threads, and the two ends of the sliding frame 29 slide through the sliding groove 26, the sliding frame 29 will slide along the sliding groove 26. Since the two ends of the movable plate 30 are rotatably connected to the sliding frame 29 and the mounting base 25 respectively, the movable plate 30 will change its angle, causing the movable plate 30 to push the mounting base 25 upward, causing the mounting base 25 to rotate along one end of the shaft, causing the mounting base 25 to tilt at an angle, lifting the rear end of the wind turbine blade, thereby facilitating the transportation of the wind turbine blade.

[0039] When the specifications of the fixed flange 1 need to be changed according to usage requirements, firstly, rotate the mating plate 4 in the forward direction. The mating plate 4 will drive the mating hole 5 and the reset block 7 on one side to rotate in the forward direction. Then, the reset block 7 and the fixed block 8 cooperate to press the reset spring 9, and the reset block 7 will drive the reset rod 48 on one side to rotate in the forward direction along the reset hole 49. When the reset spring 9 is pressed to its limit, the mating hole 5 just rotates to a position concentric with the return rod 21. Then, push the moving sleeve 6. The moving sleeve 6 will drive the inner guide block 45 to slide along the guide groove 46, and the moving sleeve 6 will simultaneously drive the return rod 21 on one side to slide into the return hole. At the same time, the moving sleeve 6 and the mating plate 4 cooperate to press the return spring 47, so that the moving sleeve 6 no longer limits the outer wall of the moving plate 14. When the adapter 11 rotates in the forward direction, it drives one side of the movable frame 12 to rotate in the forward direction. The movable frame 12 then drives the movable rod 13, the movable spring 15, and the movable plate 14 to rotate in the forward direction. The inner wall of the movable groove 10 then presses against one end of the movable rod 13. Due to the rounded corner design at the edge of the inner wall of the movable groove 10 and one end of the movable rod 13, one end of the movable rod 13 slides out of the movable groove 10. The movable rod 13 then drives the other end of the movable plate 14 to slide outward, causing the movable plate 14 to pull the movable spring 15 outward. At the same time, the adapter 11 drives the adapter groove 23 to rotate in the forward direction. When the adapter groove 23 rotates to the position corresponding to the adapter plate 17, the rotation of the adapter 11 stops. At this time, the inner wall of the adapter 11 no longer presses against the outer wall of the adapter plate 17. The wall is limited, and then the fastening sleeve 3 is pulled outward. The fastening sleeve 3 will then drive the fastening block 18 and other components to move, causing the inner wall of the fastening groove 20 to press against one end of the fastening block 18. Due to the hemispherical structure design of one end of the fastening block 18 and the arc-shaped structure design of the fastening groove 20, one end of the fastening block 18 will gradually slide out of the fastening groove 20. The fastening block 18 will then drive one side of the adapter plate 17 to slide outward through the adapter groove 23, and the adapter plate 17 will drive one side of the adapter spring 22 to stretch outward. When the fastening sleeve 3 is completely removed, the adapter spring 22 resets and pulls the adapter plate 17, causing the adapter plate 17 and the adapter spring 22 to retract into the relief groove 16. The adapter plate 17 will then drive one side of the fastening block 18 to slide inward and reset, thereby achieving complete removal of the fastening sleeve 3. Next, following the steps described above, remove the other two fastening sleeves 3. Then, remove the fixing flange 1 from one side of the sliding block 42 and replace it. After replacement, reattach the replaced fixing flange 1 to one side of the sliding block 42, allowing the fastening rod 2, which is fixedly connected to one side of the fixing flange 1, to slide through the pre-drilled mounting hole on the sliding block 42. Then, fit the fastening sleeve 3 onto the outside of the fastening rod 2 from the other side. The inclined structure at the outer end of the top block 19 then pushes the fastening block 18 outward, causing the fastening block 18 to again drive the adapter plate 17 on one side to slide outward. The adapter plate 17 will then again drive the adapter spring 22 to stretch outward. When the fastening sleeve 3 is fully fitted onto the outside of the fastening rod 2, the fastening block 18 corresponds to the position of the fastening groove 20.Then, the adapter spring 22 resets and pulls the adapter plate 17, causing the adapter plate 17 to slide the fastening block 18 on one side inwards, so that one end of the fastening block 18 is reinserted into the fastening groove 20, and the adapter spring 22 causes the adapter plate 17 to slide back into the relief groove 16. At this time, the adapter 11 is rotated in the opposite direction, which will cause the adapter groove 23 and the moving frame 12 on one side to rotate in the opposite direction, so that the moving frame 12 drives the moving rod 13, the moving spring 15, and the moving plate 14 to rotate in the opposite direction. After the groove 23 is rotated and reset, the inner wall of the adapter 11 limits the outer wall of the adapter plate 17, preventing the fastening block 18 and the adapter plate 17 from moving outward. At this time, the moving frame 12 drives the moving rod 13 and other components to rotate and reset to the position corresponding to the original moving groove 10. Then, the moving spring 15 resets and pulls the moving plate 14, causing the moving plate 14 to slide the moving rod 13 inward and reset. Then, one end of the moving rod 13 will be reinserted into the original moving groove 10. Then, the moving sleeve 6 is released, and the return spring 47 pushes the moving sleeve... 6 drives the inner guide block 45 to slide and reset along the guide groove 46, and the moving sleeve 6 will drive the return rod 21 on one side to slide and reset. When the return spring 47 is fully reset, the return rod 21 is fully reset to the original side of the mating plate 4, so that the return rod 21 no longer limits the mating plate 4 through the mating hole 5. Then the reset spring 9 pushes the reset block 7 to rotate in the opposite direction to reset. Then the reset block 7 will drive the reset rod 48 on one side to rotate in the opposite direction along the reset hole 49 to reset, and the reset block 7 will drive the mating hole 5 to rotate and reset through the mating plate 4 to no longer be in contact with the return spring 47. The return rod 21 supports the moving sleeve 6 to one side of the mating plate 4. The guide block 45 and guide groove 46 limit the movement of the moving sleeve 6, preventing it from moving. The inner wall of the moving sleeve 6 then limits the outer wall of the moving plate 14, preventing the moving plate 14 and the moving rod 13 from sliding outwards. Finally, the moving rod 13 and the moving groove 10 work together to lock and position the moving frame 12, preventing accidental rotation of the moving frame 12 and the mating plate 11, thus ensuring a stable installation of the fixed flange 1.
