However, the airbags can experience unstable pressure maintenance and pressure relief, posing safety risks during the lifting process. Furthermore, existing wind turbine blade lifting fixtures lack the ability to adjust the blade lifting angle, requiring manual alignment on-site, posing a safety hazard. Utility Model Content

[0030] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, a detailed description of the specific embodiments of the present invention is now provided with reference to the accompanying drawings. In the following description, it should be understood that, unless otherwise expressly specified or limited, terms such as "connected" and "disposed" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; internal connections between two elements, or interactions between two elements. When an element is referred to as being "on" or "under" another element, the element can be "directly" or "indirectly" located above the other element, or one or more intervening elements may be present. The terms "first," "second," and "third," etc., are used solely to facilitate the description of the present technical solution and should not be construed to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, features designated as "first," "second," and "third," etc., may explicitly or implicitly include one or more of such features. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0031] See also Figure 1 The present invention illustrates an embodiment of a wind turbine blade lifting beam (hereinafter referred to as a lifting beam), which can be used to lift blades for offshore or onshore wind turbines. The lifting beam comprises a first base 1, a clamping mechanism 2, a lifting strap 3, and a blade angle adjustment unit 4. The first base 1 serves as a mounting base for the blade angle adjustment unit 4, the clamping mechanism 2, and the lifting strap 3. The blade angle adjustment unit 4, the clamping mechanism 2, and the lifting strap 3 are each connected to the first base 1.

[0032] A limiting space 5 is defined between the clamping mechanism 2 and the sling 3. The limiting space 5 is used to accommodate and limit the blades of the fan (not shown). The sling 3 is used to support the lower part of the blade. The clamping mechanism 2 can extend in the direction close to the sling 3 or retract in the direction away from the sling 3. When the clamping mechanism 2 extends in the direction close to the sling 3, the limiting space 5 gradually becomes smaller, and the clamping mechanism 2 can fit the blade. When the clamping mechanism 2 retracts in the direction away from the sling 3, the limiting space 5 gradually becomes larger, and the clamping mechanism 2 can separate from the blade to loosen the blade. Therefore, the extension and retraction actions of the clamping mechanism 2 can adapt to blades of different sizes, and the blade can be clamped between the clamping mechanism 2 and the sling 3.

[0033] The blade angle adjustment unit 4 includes at least four riggings 41 and at least four length adjustment mechanisms 42, and the riggings 41 and the length adjustment mechanisms 42 are connected in a one-to-one correspondence. That is, there are four or more riggings 41, and the number of length adjustment mechanisms 42 is consistent with the number of riggings 41, and each length adjustment mechanism 42 is connected to a corresponding rigging 41. The rigging 41 can be a rope, a chain, etc. Further, in different embodiments, the rigging 41 can be connected to the first base 1, or the length adjustment mechanism 42 can be connected to the first base 1. The length adjustment mechanism 42 itself can change its length by telescoping, so the length adjustment mechanism 42 is used to adjust the length of the blade angle adjustment unit 4. Since each length adjustment mechanism 42 is connected to a corresponding rigging 41, each blade angle adjustment unit 4 can adjust its length. By adjusting the length of each blade angle adjustment unit 4, the blade can be placed horizontally or tilted.

[0034] The present invention's lifting beam is particularly suitable for situations where blades need to be docked with a tower mid-air. Due to the high wind speeds and poor visibility during mid-air docking, the position of both the lifting beam and the blades mounted on it are easily affected by the external environment. The four blade angle adjustment units 4 provide four degrees of freedom for blade angle adjustment, offering a wide range of angle adjustments and making them more suitable for mid-air docking scenarios.

[0035] When installing the blades, first set the relative position between the blades and the suspension beam: move the suspension beam to the top of the blade, and align the center of mass of the blade and the center of mass of the suspension beam roughly on the same plumb line. Then, install the blade into the limited space 5 and press it between the clamping mechanism 2 and the sling 3. Adjust the lengths of the four blade angle adjustment units 4 through four length adjustment mechanisms 42 so that the lengths of the four blade angle adjustment units 4 are equal. At this time, the four blade angle adjustment units 4 are balanced in force, and the blades are in a horizontal position. Then, use a lifting device (not shown) to lift the suspension beam and lift the blades into the air to dock with the tower. When docking with the tower, if the angle of the blade needs to be changed, operate the length adjustment mechanism 42 to change the length of one or more blade angle adjustment units 4. At the same time, since the blades can be pressed between the clamping mechanism 2 and the sling 3, the blades can obtain stable limited support at different angles.

[0036] In summary, for the suspension beam of the present invention, the blades can be accommodated in the limited space 5 defined by the clamping mechanism 2 and the sling 3, so that the blades are clamped between the clamping mechanism 2 and the sling 3. The clamping mechanism 2 can extend in the direction close to the sling 3 or retract in the direction away from the sling 3 to adapt to blades of different sizes. The stability of the blades during movement is ensured by the cooperation of the clamping mechanism 2 and the sling 3. There is no need for airbags or other devices, so there is no need to consider pressure maintenance issues, and the posture of the blades can be effectively maintained to reduce the impact of wind loads. At the same time, by adjusting the lengths of the four blade angle adjustment units 4 through four length adjustment mechanisms 42, the lifting angle of the blades can be changed to adapt to different docking requirements. The four blade angle adjustment units 4 can provide four degrees of freedom for blade angle adjustment, provide more angle adjustment space, and can be better applied to docking scenarios in the air.

[0037] like Figure 3 As shown, in some embodiments, the length adjustment mechanism 42 includes a hydraulic cylinder 421, a hydraulic power unit 422, a hydraulic reversing valve 423 and a hydraulic sensor 424. The hydraulic cylinder 421 is connected to the rigging 41. Specifically, as Figure 1 As shown, in the first embodiment, one end of the rigging 41 is connected to the first base 1, and the other end of the rigging 41 is used to connect to the lifting equipment. The hydraulic cylinder 421 has an output end and a fixed end, the output end refers to the end where its output shaft is located, and the fixed end is the other end away from the output shaft. The hydraulic cylinder 421 is located between the two ends of the rigging 41, and the output end and the fixed end of the hydraulic cylinder 421 are respectively connected to the rigging 41. The output shaft of the hydraulic cylinder 421 can be extended and retracted. When the output shaft of the hydraulic cylinder 421 is extended and retracted, the length of the length adjustment mechanism 42 changes accordingly, so that, as a whole, the length of the blade angle adjustment unit 4 changes accordingly. Figure 2As shown, in the second embodiment, unlike the first embodiment, one end of the rigging 41 is connected to the first base 1, and the other end of the rigging 41 is connected to the output end of the hydraulic cylinder 421. The fixed end of the hydraulic cylinder 421 is used to connect to the lifting equipment. In the third embodiment (not shown), unlike the first embodiment, the output end of the hydraulic cylinder 421 is connected to the first base 1, and the fixed end of the hydraulic cylinder 421 is connected to one end of the rigging 41, and the other end of the rigging 41 is used to connect to the lifting equipment.

[0038] Please continue reading Figure 3 Hydraulic power unit 422 is connected to hydraulic cylinder 421 to provide power to hydraulic cylinder 421, thereby driving the output shaft of hydraulic cylinder 421 to extend and retract. Hydraulic reversing valve 423 is connected to hydraulic power unit 422 to control the flow of oil, thereby controlling the movement direction of hydraulic cylinder 421. Hydraulic sensor 424 is connected to hydraulic cylinder 421 to monitor and control the pressure of the hydraulic oil.

[0039] Specifically, the hydraulic power unit 422 may include one or more hydraulic pumps, an oil tank, a filter, and a motor to drive the pump. The hydraulic pump converts mechanical energy into hydraulic energy. The hydraulic cylinder 421 is an actuator that converts hydraulic energy into mechanical energy to achieve reciprocating linear motion. The hydraulic reversing valve 423 controls the flow direction of the hydraulic oil, thereby changing the movement direction of the hydraulic cylinder 421. The hydraulic reversing valve 423 can be motorized, electromagnetic, hydraulic, or electro-hydraulic controlled, which controls the oil flow path by changing the position of the valve core. The hydraulic sensor 424 monitors the pressure, flow, or other parameters in the hydraulic cylinder 421, and converts this information into electrical signals for feedback and monitoring the displacement of the blade angle adjustment unit 4. Correspondingly, in order to achieve automatic control, a control system can be installed on the ground. The control system is communicated with the hydraulic reversing valve 423, the hydraulic power unit 422 and the hydraulic sensor 424, and can receive the electrical signal fed back by the hydraulic sensor 424 to obtain the real-time displacement of the hydraulic cylinder 421; the control system can also control the action of the hydraulic reversing valve 423, thereby realizing remote closed-loop control of the extension and retraction of the hydraulic cylinder 421.

[0040] Through the coordinated operation of the hydraulic cylinder 421, the hydraulic power unit 422, the hydraulic reversing valve 423 and the hydraulic sensor 424, the operator can accurately control the length of each blade angle adjustment unit 4 on the ground, thereby monitoring and adjusting the lifting angle of the blade in real time.

[0041] like Figures 4 to 6As shown, in some embodiments, the clamping mechanism 2 includes a second base 21, a drive unit 22, and an abutment 23. The second base 21 is connected to the first base 1, and the drive unit 22 is disposed on the second base 21. The drive unit 22 is in transmission connection with the abutment 23. The abutment 23 is configured to contact the blades. Specifically, driven by the drive unit 22, the abutment 23 can move toward or away from the sling 3, thereby compressing the blades within the confining space 5. Figure 4 The initial state of the pressing mechanism 2 is shown (the output shaft of the drive unit 22 is not extended). Figure 6 The clamping mechanism 2 is shown in an extended state (the output shaft of the drive unit 22 is extended).

[0042] There can be multiple drive units 22. For example Figures 4 to 6 In the illustrated embodiment, two drive units 22 are symmetrically arranged on the second base 21. The drive unit 22 is a linear motion mechanism, which may include one of a pneumatic cylinder, a hydraulic cylinder, and an electric cylinder.

[0043] In some embodiments, the abutment member 23 is an elastic member. For example, the abutment member 23 can be a rubber member, a silicone member, etc. The elastic properties of the abutment member 23 can make it fit tightly with the blade while preventing damage to the blade.

[0044] In some embodiments, the abutment member 23 is detachably connected to the bottom of the second base 21. Specifically, Figure 5 In the illustrated embodiment, the abutment 23 is provided with a plurality of first bolt holes 230, and the bottom of the second base 21 is provided with a plurality of second bolt holes, with the first bolt holes 230 and the second bolt holes being aligned one by one. By sequentially inserting the first bolt 61 through the first bolt hole 230 and the second bolt hole, the abutment 23 can be detachably connected to the bottom of the second base 21. Of course, in other embodiments, the abutment 23 and the second base 21 can also be detachably connected by other means, such as a chimeric / snap-on connection. Thus, the abutment 23 can be disassembled and replaced as needed to accommodate blades of different sizes and wind turbines of different specifications.

[0045] like Figure 7 As shown, in some embodiments, the abutment member 23 has a curved surface 232 for contacting the blade. Specifically, the abutment member 23 has a curved surface 232 on the side facing away from the second base 21. This curved surface 232 is recessed as it approaches the second base 21, thereby better fitting the outer circumference of the blade. Compared to the airbag, the abutment member 23 contacts the blade via the curved surface 232, resulting in a larger contact area between the two.

[0046] like Figures 4 to 6 As shown, in some embodiments, the pressing mechanism 2 further includes a roller 24 connected to the second base 21. Figure 8As shown, in some embodiments, a slide groove 10 is provided on the first base 1. The roller 24 slides in engagement with the slide groove 10. Thus, the clamping mechanism 2 can slide relative to the first base 1 to change the relative position between the clamping mechanism 2 and the sling 3, thereby changing the relative position between the clamping mechanism 2 and the blade, making the position of the clamping mechanism 2 more flexible.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments, the first base 1 includes two end beams 12 and two intermediate beams 11. The two end beams 12 are arranged in parallel and spaced apart, and the two intermediate beams 11 are also arranged in parallel and spaced apart. Each intermediate beam 11 is connected between two end beams 12. Thus, the two end beams 12 and the two intermediate beams 11 together form a rectangle. One end beam 12 is relatively closer to the tip of the blade, and the other end beam 12 is relatively closer to the root of the blade.

[0048] Correspondingly, the number of the clamping mechanisms 2 is at least two (i.e., two or more), and the two clamping mechanisms 2 are respectively connected to the two end beams 12. One of the clamping mechanisms 2 is relatively closer to the tip of the blade, and is used to clamp the tip of the blade; the other clamping mechanism 2 is relatively closer to the root end of the blade, and is used to clamp the root end of the blade. The number of the slings 3 is also at least two (i.e., two or more), and the two slings 3 are respectively connected to the two end beams 12. One of the slings 3 is relatively closer to the tip of the blade, and is used to support the tip of the blade; the other sling 3 is relatively closer to the root end of the blade, and is used to support the root end of the blade. Two of the rigging 41 are respectively connected to the opposite ends of one of the end beams 12, and the other two rigging 41 are respectively connected to the opposite ends of the other end beam 12. As Figure 1 As shown, in the working state, one end of the four blade angle adjustment units 4 away from the first base 1 is connected to the lifting equipment, and an angle is formed between adjacent rigging 41 (that is, adjacent rigging 41 are not parallel).

[0049] like Figure 9 As shown, in some embodiments, each end beam 12 is provided with a plurality of positioning holes 120 spaced apart along its length, and at least one end of the sling 3 is provided with a positioning shaft 31, which is adapted to fit within the positioning holes 120. That is, the positioning shaft 31 may be provided at one end of the sling 3, or at both ends of the sling 3. The sling 3 can be connected to different positioning holes 120 via the positioning shaft 31, thereby changing the relative position between the sling 3 and the end beam 12. Furthermore, the coordination of the positioning shaft 31 with the positioning holes 120 allows the sling 3 to be quickly and easily removed from the end beam 12, thereby facilitating installation of the blades and the sling beam.

[0050] like Figure 10As shown, in some embodiments, each intermediate beam 11 includes at least two detachably connected beam segments 110. Adjacent beam segments 110 can be connected via flanges 111. Thus, by adjusting the number of beam segments 110, the length of each intermediate beam 11 can be varied to accommodate different blade lengths.

[0051] like Figure 1 and Figure 11 As shown, in some embodiments, the suspension beam further includes at least four (i.e., four or more) support legs 7. Two of the support legs 7 are respectively connected to the opposite ends of one of the end beams 12, and the other two support legs 7 are respectively connected to the opposite ends of the other end beam 12. Each support leg 7 can move up and down relative to the end beam 12. Specifically, each support leg 7 is provided with a plurality of third bolt holes 63 arranged at intervals along the vertical direction, and the end beam 12 is provided with a fourth bolt hole. After selecting a third bolt hole 63 and aligning it with the fourth bolt hole, the second bolt 62 is inserted into the third bolt hole 63 and the fourth bolt hole to fix the position of the support leg 7. By selecting different third bolt holes 63, the height of the support leg 7 relative to the ground (or relative to the blade) can be changed. Alternatively, in some other embodiments, the relative position between each support leg 7 and the end beam 12 remains unchanged, and each support leg 7 itself can be extended and retracted up and down relative to the end beam 12, and the height of the support leg 7 relative to the ground (or relative to the blade) can also be changed. Before the blade is hoisted, the lifting beam needs to be erected on the blade first, and then the height of each supporting leg 7 needs to be adjusted to suit the blade size, while facilitating the subsequent installation and removal of the lifting belt 3.

[0052] It can be understood that the above embodiments only express the preferred implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
