Description

Technical Field

[0001] This invention relates to a wind turbine blade hoisting and support device, belonging to the field of wind turbine blade hoisting technology. Background Technology

[0002] Wind turbine blades are typically installed using cables. This involves completely looping at least two cable segments around the blade, positioning the blade's center of gravity between the two cable segments. The crane then lifts the blade to the installation location and secures it to the wind turbine's support piles. However, conventional cable routing requires the cable to completely loop around the blade from below and be fixed above it. This necessitates manually lifting or using an additional crane to attach the cable end around the blade to the crane, which is inconvenient for connecting and binding the cable to the blade. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a wind turbine blade hoisting support device, which solves the problem in the prior art that the conventional cable winding method requires the cable to be completely wrapped around the bottom of the blade and fixed at a position higher than the blade. This also requires the end of the cable wrapped around the blade to be lifted manually or by an additional crane and fixed on the hoisting machine, which is not convenient for the cable to be connected and bound to the blade.

[0004] The technical problem to be solved by this invention is achieved by the following technical solution: a wind turbine blade hoisting support device, comprising: The first support rod has two oppositely arranged components. The second support rod is fixed between the two first support rods. The assembly plate is fixed to the second support rod. Support bases are fixed to both ends of the first support rod. The winding wheel is located inside the support base. The support belt is fixed at one end to the outer side of the winding wheel. The connecting component is fixedly connected to the end of the support belt away from the winding wheel. The pressing component is located at the connection between the first support rod and the second support rod. The connecting component is used to fix two support belts located on the same first support rod to each other, and the pressing component is used to press the fan blades toward the support belts.

[0005] By adopting the above technical solution, when it is necessary to hoist the fan blade, after fixing the assembly plate to the hoisting equipment, the support belts are wrapped around the bottom of the fan blade and connected to each other using connecting components. The fan blade is supported by the two support belts during hoisting. Then, the pressing component abuts against the top of the fan blade and presses it in the direction of the support belts, so that the fan blade and the support belts are in close contact. This can ensure the stability of the fan blade during hoisting. At the same time, the two support belts are connected by connecting components, meaning that only half of the support belt needs to be wrapped around the fan blade before the two support belts can be fixed at the bottom of the fan blade using connecting components. It is not necessary to wrap the support belts around the entire fan blade, which improves the convenience of connecting the two support belts around the fan blade.

[0006] The present invention is further configured such that the connecting component includes: Connecting block, The locking cavity is located within the connecting block. The locking block is slidably positioned within the locking cavity. A locking plate is fixed to the end of the locking block away from the support band, and the end of the locking plate away from the locking block extends to the outside of the connecting block. The elastic element is fixed inside the locking cavity and located on the side of the locking block away from the locking plate. The elastic element abuts against the locking block. The locking structure is located within the locking block. In this configuration, the locking plates within the two opposing connecting blocks extend into the opposing locking cavities and are inserted into the corresponding locking blocks, and the locking structure locks the portion of the locking plates inserted into the locking blocks.

[0007] The present invention is further configured such that the locking structure includes: The magnetic suction cavity is located inside the locking block. A locking slot is formed at one end of the locking plate where the locking block is inserted; the locking slot can be aligned with the magnetic cavity. The magnetic block is slidably disposed within the magnetic cavity, with its end extending into the locking groove. An electromagnet is positioned on the side of the magnetic block away from the locking slot. The electromagnet is fixedly connected to the inner wall of the magnetic cavity. When energized, the electromagnet generates magnetism. The retaining spring is sleeved on the outside of the electromagnet, and the two ends of the retaining spring are fixed to the magnetic block and the inner wall of the magnetic cavity, respectively.

[0008] By adopting the above technical solution, two connecting blocks are set opposite each other, and the locking plates in the two connecting blocks are inserted into the locking blocks. At this time, the locking groove is aligned with the magnetic suction cavity. The magnetic suction block is inserted into the locking groove under the elastic action of the retaining spring to limit the locking plate. At this time, the two connecting blocks cannot be disconnected. When the fan blade is hoisted, it needs to be disconnected from the support belt. At this time, the electromagnet is energized and attracts the magnetic suction block. The magnetic suction block is released from the locking groove. At this time, the elastic element pulls the locking block under the elastic action, thereby pulling the locking plate out from the opposite locking block, and thus the two connecting blocks are disconnected. At this time, the two support belts are separated, thus completing the separation from the fan blade. During the fan blade hoisting process, even if the hoisting equipment loses power due to external factors, the locking plate and the locking block are still restricted to separation by the magnetic suction block, which helps to improve the safety of fan blade hoisting.

[0009] The invention is further configured such that: an airbag is fixedly provided at the connection between the support belt and the connecting block, and a one-way valve for filling the airbag with air is fixedly provided on the airbag.

[0010] By adopting the above technical solution, and connecting the one-way valve to an external inflation device, the airbag can be inflated to fill the gap between the connecting block and the support belt and the fan blade, thus preventing the support belt and the connecting block from breaking due to excessive force, and further improving the safety of fan blade hoisting.

[0011] The present invention is further configured such that the pressing component includes: Two hinge plates are fixed to the first support rod and are arranged opposite each other. A flip-up pressing plate is positioned between two hinged plates. One end of the flip-up pressing plate is hinged to the hinged plate, and the other end extends towards the first support rod in a direction away from the second support rod. A cylinder is fixed to the first support rod, and an output rod is provided on the cylinder. One end of the output rod passes through the first support rod and extends to the flip-up pressing plate. The pressing block is fixed to the end of the output rod facing the flip pressing plate and abuts against the flip pressing plate. The baffle is fixed to the side of the hinge plate opposite to the pressing block. When the pressing plate is flipped, the portion between the hinge plates can abut against the baffle. An emergency structure, located between the hinge plates and on the side of the flip-up pressing plate away from the first support rod, is used to limit the tilt angle of the flip-up pressing plate.

[0012] By adopting the above technical solution, the cylinder is activated to press the pressing block through the output rod, causing the pressing block to flip the pressing plate along the hinge end, and the end of the flipped pressing plate abuts against the fan blade. At this time, the flipped pressing plate applies pressure to the fan blade toward the support belt, making the fan blade fit more tightly with the support belt, thereby ensuring the stability of the fan blade during hoisting.

[0013] The present invention is further configured such that the emergency structure includes: Mounting blocks are fixed between the hinge plates. The movable cavity is located within the mounting block. The emergency block has one end inserted into the movable cavity, and the other end extends to the flip-up pressing plate. The emergency block slides vertically. The trigger channel runs through the emergency block. The trigger plate is slidably disposed within the trigger channel, with one end of the trigger plate located within the trigger channel and the other end of the emergency block extending to the outside of the emergency block and abutting against the flip-up pressing plate. The elastic cavity is located to the side of the trigger channel. The fixed plate is slidably disposed within the elastic cavity and fixedly connected to the trigger plate. The elastic spring has one end fixed to the inner wall of the elastic cavity, and the other end fixed to the fixing plate. A limiting structure is installed inside the movable cavity and located on both sides of the emergency block. The limiting structure is used to restrict the sliding of the emergency block. The elastic part is located in the part where the emergency block is inserted into the movable cavity, and the elastic part is used to provide elastic support for the emergency block.

[0014] The present invention is further configured such that the limiting structure includes: The limiting block extends partially to the opening of the trigger channel. The side of the limiting block facing the trigger channel is inclined, and the inclined surface can abut against the end of the trigger plate. A limiting groove is formed on the side of the emergency block facing the limiting block. The limiting block portion penetrates the inner wall of the movable cavity and extends into the limiting groove to restrict the sliding of the emergency block. The limiting spring is fixed between the side of the limiting block away from the emergency block and the inner wall of the movable cavity.

[0015] The invention is further configured such that: the elastic part includes an emergency spring disposed on the side of the movable cavity away from the emergency block, one end of the emergency spring is fixed to the inner wall of the movable cavity, the other end of the emergency spring is fixed to the end of the emergency block inserted into the movable cavity, and a guide post is disposed inside the emergency spring and fixedly connected to the inner wall of the movable cavity, the guide post restricting the movement direction of the emergency spring.

[0016] By adopting the above technical solution, when the fan blades vibrate significantly and the hinge end of the flip-up pressing plate suddenly breaks, the hinge end of the flip-up pressing plate will move towards the mounting block after breaking, pressing the trigger plate. This causes the end of the trigger plate located in the trigger channel to insert into the movable cavity and squeeze the inclined surface of the limiting block. After being squeezed, the limiting block moves away from the emergency block and compresses the limiting spring. At this time, the limiting block disengages from the limiting groove and releases the limiting effect on the emergency block. Under the elastic action of the emergency spring, the emergency block quickly moves towards the flip-up pressing plate. The pressing plate springs up and abuts against the hinged end of the flip pressing plate. At this time, the part of the flip pressing plate located inside the hinged plate can abut against the baffle as the hinged end of the flip pressing plate moves upward, thereby preventing the hinged end of the flip pressing plate from coming off between the hinged plates. At this time, the end of the flip pressing plate away from the hinge is still pressed stably on the fan blade. The superimposed emergency block applies an upward force to the flip pressing plate, which can keep the flip pressing plate stable and prevent the hinged end of the flip pressing plate from breaking and causing the hinged plate to come off, thus preventing the flip pressing plate from failing as a whole.

[0017] The beneficial effects of this invention are as follows: When it is necessary to hoist the fan blade, after fixing the assembly plate to the hoisting equipment, the support belts are wrapped around the bottom of the fan blade and connected to each other using connecting components. The fan blade is supported by the two support belts during hoisting. Then, the pressing component abuts against the top of the fan blade and presses it in the direction of the support belts, so that the fan blade and the support belts are in close contact. At this time, the stability of the fan blade during hoisting can be guaranteed. At the same time, the two support belts are connected by connecting components, that is, only half of the support belt needs to be wrapped around the fan blade, and the two support belts can be fixed at the bottom of the fan blade using connecting components. It is not necessary to wrap the support belts around the entire fan blade. This improves the convenience of connecting the two support belts around the fan blade. Attached Figure Description

[0020] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.

[0021] like Figure 1-2 As shown, a wind turbine blade hoisting support device includes a first support rod 10, a second support rod 11, an assembly plate 12, a support base 14, a winding wheel 15, a support belt 16, a connecting assembly, and a pressing assembly. Two first support rods 10 are arranged opposite each other, and a second support rod 11 is fixed between the two first support rods 10, forming an I-shaped structure. The assembly plate 12 is fixed to the second support rod 11 and is fixedly connected to external hoisting equipment by bolts. The support base 14 is fixed to both ends of the first support rod 10. The winding wheel 15 is disposed inside the support base 14. One end of the support belt 16 is fixed to the outer side of the winding wheel 15. The connecting assembly is fixedly connected to the end of the support belt 16 away from the winding wheel 15, and the connecting assembly is used to fix the two support belts 16 located on the same first support rod 10 to each other. The pressing assembly is disposed at the connection between the first support rod 10 and the second support rod 11, and is used to press the blade towards the support belt 16. When the winding wheel 15 and the support base 14 are rotatably connected, through slots need to be made on the support base 14 and the winding wheel 15 along the rotation axis of the winding wheel 15. After the winding wheel 15 rotates to an appropriate position, a positioning pin is inserted into the through slot to lock the support base 14 and the winding wheel 15, preventing the winding wheel 15 from rotating. At this time, the length of the support belt 16 remains stable. When it is necessary to adjust the length of the support belt 16, the positioning pin is removed, the winding wheel 15 is rotated, and the length of the support belt 16 wound on the winding wheel 15 is adjusted. After adjustment, the positioning pin is reinserted into the through slot to lock the winding wheel 15. This achieves the purpose of adjusting the length of the support belt 16. The winding wheel 15 and the support base 14 can also be set as a fixed connection, in which case the length of the support belt 16 cannot be changed.

[0022] like Figure 3As shown, the connecting assembly includes a connecting block 17, a locking cavity 34, an elastic element 35, a locking block 36, a locking plate 37, and a locking structure. The locking cavity 34 is located within the connecting block 17. The locking block 36 is slidably disposed within the locking cavity 34. The locking plate 37 is fixed to the end of the locking block 36 away from the support belt 16, and the end of the locking plate 37 away from the locking block 36 extends to the outside of the connecting block 17. The elastic element 35 is fixed within the locking cavity 34 and located on the side of the locking block 36 away from the locking plate 37, abutting against the locking block 36. The locking plates 37 in two opposing connecting blocks 17 extend into their respective locking cavities 34 and insert into their corresponding locking blocks 36. The locking structure is disposed within the locking block 36, locking the portion of the locking plate 37 inserted into the locking block 36, preventing the locking plate 37 from dislodging from the locking block 36. An airbag 18 is fixedly disposed at the connection between the support belt 16 and the connecting block 17, and a one-way valve for inflating air into the airbag 18 is fixedly disposed on the airbag 18.

[0023] like Figure 3 As shown, the locking structure includes a locking groove 38, a magnetic cavity 39, a magnetic block 40, an electromagnet 41, and a retaining spring 42. The magnetic cavity 39 is located within the locking block 36, and the locking groove 38 is located at one end of the locking plate 37 that is inserted into the locking block 36. When the locking plate 37 is inserted into another locking block 36, the locking groove 38 aligns with the magnetic cavity 39. The magnetic block 40 is slidably disposed within the magnetic cavity 39, with its end extending into the locking groove 38. The electromagnet 41 is disposed on the side of the magnetic block 40 away from the locking groove 38 and is fixedly connected to the inner wall of the magnetic cavity 39. When energized, the electromagnet 41 generates magnetism and attracts the magnetic block 40. The retaining spring 42 is sleeved on the outside of the electromagnet 41, with both ends of the retaining spring fixed to the magnetic block 40 and the inner wall of the magnetic cavity 39, respectively. The retaining spring 42 is made of an anti-magnetic material, such as copper alloy or stainless steel. The power supply cable of electromagnet 41 extends to the ground through the boom of the hoist and is electrically connected to the built-in battery of the hoist. The hoist is equipped with a control module that controls the on and off of electromagnet 41. The structure and principle of the control module are the same as those of conventional electromagnets.

[0024] like Figure 1 and Figure 4As shown, the pressing assembly includes a hinge plate 13, a cylinder 19, a pressing block 20, a flip pressing plate 21, a baffle 43, and an emergency structure. The hinge plate 13 is fixed on the first support rod 10, and there are two hinge plates 13 arranged opposite each other. The flip pressing plate 21 is arranged between the two hinge plates 13. One end of the flip pressing plate 21 is hinged to the hinge plate 13, and the other end of the flip pressing plate 21 extends toward the first support rod 10 away from the second support rod 11. The cylinder 19 is fixed on the first support rod 10, and an output rod is provided on the cylinder 19. One end of the output rod extends through the first support rod 10 to the flip pressing plate 21. The pressing block 20 and the output rod are fixed to one end facing the flip pressing plate 21 and abut against the flip pressing plate 21. The baffle 43 is fixed on the side of the hinge plate 13 opposite to the pressing block 20. The part of the flip pressing plate 21 located between the hinge plates 13 can abut against the baffle 43. The emergency structure is set between the hinge plates 13 and located on the side of the flip pressing plate 21 away from the first support rod 10. The emergency structure is used to limit the tilt angle of the flip pressing plate 21.

[0025] like Figure 5 and Figure 6 As shown, the emergency structure includes a mounting block 22, a movable cavity 23, an emergency block 26, a trigger channel 27, a spring cavity 28, a trigger plate 29, a fixing plate 30, a spring spring 31, a limiting structure, and an elastic part. The mounting block 22 is fixed between the hinge plates 13. The movable cavity 23 is opened inside the mounting block 22. One end of the emergency block 26 is vertically inserted into the movable cavity 23, and the other end of the emergency block 26 extends to the flip-up pressing plate 21. The emergency block 26 slides vertically. The trigger channel 27 is vertically opened through the emergency block 26. The trigger plate 29 is slidably disposed in the trigger channel 27. One end of the trigger plate 29 is located inside the trigger channel 27, and the other end of the emergency block 26 extends to the outside of the emergency block 26 and abuts against the flip-up pressing plate 21. The elastic cavity 28 is located laterally to the trigger channel 27. The fixing plate 30 is slidably disposed within the elastic cavity 28 and partially extends into the trigger channel 27, where it is fixedly connected to the trigger plate 29. One end of the elastic spring 31 is fixed to the inner wall of the elastic cavity 28, and the other end is fixed to the fixing plate 30. The elastic force of the elastic spring 31 is greater than the weight of the trigger plate 29. A limiting structure is disposed within the movable cavity 23 and located on both sides of the emergency block 26. The limiting structure is used to restrict the sliding of the emergency block 26. An elastic part is disposed at the portion of the emergency block 26 inserted into the movable cavity 23, and the elastic part is used to provide elastic support for the emergency block 26.

[0026] like Figure 5 and Figure 6As shown, the limiting structure includes a limiting block 24, a limiting spring 25, and a limiting groove 33. The limiting block 24 extends to the opening of the trigger channel 27, and the side of the limiting block 24 facing the trigger channel 27 is inclined, which can abut against the end of the trigger plate 29. The limiting groove 33 is formed on the side of the emergency block 26 facing the limiting block 24. The limiting block 24 extends through the inner wall of the movable cavity 23 and into the limiting groove 33 to restrict the sliding of the emergency block 26. The limiting spring 25 is fixed between the side of the limiting block 24 away from the emergency block 26 and the inner wall of the movable cavity 23. The elastic part includes an emergency spring 32 disposed on the side of the movable cavity 23 away from the emergency block 26. One end of the emergency spring 32 is fixed to the inner wall of the movable cavity 23, and the other end of the emergency spring 32 is fixed to the end of the emergency block 26 inserted into the movable cavity 23. A guide post is disposed inside the emergency spring 32 and fixedly connected to the inner wall of the movable cavity 23. The guide post restricts the movement direction of the emergency spring 32. The elastic force of the emergency spring 32 enables the emergency block 26 to stably abut against the baffle 43 at the part of the flip-up pressing plate 21 located between the hinge plates 13.

[0027] When the fan blades need to be hoisted, after fixing the assembly plate 12 to the hoisting equipment, the support belts 16 are wrapped around the bottom of the fan blades and connected to each other using the connecting components. This allows the fan blades to be supported by the two support belts 16 during hoisting. Then, the pressing component abuts against the top of the fan blades and presses towards the support belts 16, ensuring close contact between the fan blades and the support belts 16. This ensures the stability of the fan blades during hoisting. At the same time, the two support belts 16 are connected by the connecting components. This means that only half of the support belts 16 need to be wrapped around the fan blades before the connecting components can be used to fix the two support belts 16 at the bottom of the fan blades. It is not necessary to wrap the support belts 16 around the entire fan blades, which improves the convenience of connecting the two support belts 16 around the fan blades.

[0028] Two connecting blocks 17 are positioned opposite each other, and the locking plates 37 inside the two connecting blocks 17 are inserted into the locking blocks 36. At this time, the locking groove 38 is aligned with the magnetic suction cavity 39. The magnetic suction block 40 is inserted into the locking groove 38 under the elastic action of the retaining spring 42 to limit the locking plate 37. At this time, the two connecting blocks 17 cannot be disconnected. When the fan blade is hoisted, it needs to be disconnected from the support belt 16. At this time, the electromagnet 41 is energized and attracts the magnetic suction block 40. The magnetic suction block 40 is released from the locking groove 38. At this time, the elastic element 35 pulls the locking block 36 under the elastic action, thereby pulling the locking plate 37 out of the opposite locking block 36, and thus the two connecting blocks 17 are disconnected. At this time, the two support belts 16 are separated, thus completing the separation from the fan blade. During the fan blade hoisting process, even if the hoisting equipment is de-energized due to external factors, the locking plate 37 and the locking block 36 are still restricted to separation by the magnetic suction block 40, which helps to improve the safety of fan blade hoisting.

[0029] By connecting the one-way valve to an external inflation device, the airbag 18 can be inflated to fill the gap between the connection point of the connecting block 17 and the support belt 16 and the fan blade, thus preventing the support belt 16 and the connecting block 17 from breaking due to excessive force, and further improving the safety of the fan blade hoisting.

[0030] By activating the cylinder 19, the output rod presses the pressing block 20, causing the pressing block 20 to press and flip the pressing plate 21 along the hinge end, and causing the end of the flip pressing plate 21 to abut against the fan blade. At this time, the flip pressing plate 21 applies pressure to the fan blade toward the support belt 16, making the fan blade fit more tightly with the support belt 16, thereby ensuring the stability of the fan blade during hoisting.

[0031] When the fan blades vibrate significantly, the force acting on the hinge end of the flip-up pressing plate 21 increases. If the hinge end of the flip-up pressing plate 21 suddenly breaks, it will move towards the mounting block 22 and press against the trigger plate 29. This causes the end of the trigger plate 29 located in the trigger channel 27 to insert into the movable cavity 23 and press against the inclined surface of the limiting block 24. After being compressed, the limiting block 24 moves away from the emergency block 26 and compresses the limiting spring 25. At this point, the limiting block 24 disengages from the limiting groove 33 and releases its restriction on the emergency block 26. Under the elastic action of the emergency spring 32, the emergency block 26 quickly... The flip-up pressing plate 21 quickly bounces up and abuts against the hinge end of the flip-up pressing plate 21. At this time, the part of the flip-up pressing plate 21 located inside the hinge plate 13 can abut against the baffle 43 as the hinge end of the flip-up pressing plate 21 moves upward, thereby preventing the hinge end of the flip-up pressing plate 21 from coming out between the hinge plates 13. At this time, the end of the flip-up pressing plate 21 away from the hinge is still pressed stably on the fan blade. The superimposed emergency block 26 applies an upward force to the flip-up pressing plate 21, which can keep the flip-up pressing plate 21 stable and prevent the hinge end of the flip-up pressing plate 21 from breaking and causing the hinge plate 13 to come out, thus causing the flip-up pressing plate 21 to fail as a whole.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
