[0067] In order to better understand the present application, the following will be described in combination with Figures 1 to 16 The tower drum mold and the preparation method of the tower drum of the embodiments of the present application will be described in detail.

[0068] Please refer to Figure 1 , Figure 1 is a working schematic diagram of a single-blade angle adjusting tool provided by the embodiments of the present application. Figure 1 In the drawings, only the positions of the blade and the single-blade angle adjusting tool are schematically shown.

[0069] As shown in Figure 1 , the embodiments of the first aspect of the present application provide a single-blade angle adjusting tool, which is used for blade hoisting, and the tip 11 of the blade 1 is located in the tip fixing part 20. The single-blade angle adjusting tool comprises a tip support assembly 2 and a root support assembly 3.

[0070] As shown in Figure 1 , the tip support assembly 2 is used for supporting the tip fixing part 20, so that the tip located in the tip fixing part 20 rotates relative to the tip support assembly 2 around the axis of the blade. That is, the tip support assembly 2 is used for supporting the tip through the tip fixing part 20 and rotating the tip around the axis of the blade, and the tip realizes the purpose of rotating relative to the axis of the blade through the tip support assembly 2. The axis of the blade extends along the length direction of the blade, that is, the axis of the blade 1 extends along the direction from the root 12 to the tip 11. Figure 1 In the drawings, the axis of the blade is schematically shown by a dot-dash line, and the dot-dash line does not constitute a limitation on the structure of the blade, Figure 1 The first axis AA in the drawings is the axis of the blade.

[0071] Please refer to Figure 1 the drawings Figure 2 , Figure 2 is a structural schematic diagram of a root support assembly of a single-blade angle adjusting tool provided by the embodiments of the present application.

[0072] As shown in Figure 2As shown, the blade root support assembly 3 comprises a blade root support body part 30 and a rotating part 31, the rotating part 31 is rotatably arranged on the blade root support body part 30 for supporting the rotation of the blade root. That is, the rotating part 31 is used to support the rotation of the blade root relative to the blade root support body part 30, and the blade root realizes its own purpose of following the rotation of the blade tip relative to the support body through the rotating part 31.

[0073] In the single-blade angle adjustment tool provided by the embodiment of the present application, the single-blade angle adjustment tool comprises a blade tip support assembly 2 and a blade root support assembly 3. The blade comprises a blade tip and a blade root, and the blade tip is usually limited in the blade tip fixing part 20 during the hoisting process of the blade. The blade tip support assembly 2 in the single-blade angle adjustment tool provided by the embodiment of the present application can support the blade tip fixing part 20, and the blade tip support assembly 2 can make the blade tip in the blade tip fixing part 20 rotate around the axis of the blade, thereby facilitating the quick adjustment of the position of the blade tip before hoisting. At the same time, the rotating part 31 of the blade root support assembly 3 is rotatably arranged relative to the blade root support body part 30, so that the blade root supported on the rotating part 31 can rotate. Therefore, when the position of the blade tip is adjusted through the blade tip support assembly 2, the blade root can rotate with the rotation of the blade tip through the rotating part 31, realizing the follow-up of the blade root relative to the blade tip, which can effectively improve the efficiency of the position adjustment of the blade, and further effectively improve the hoisting efficiency of the single blade.

[0074] In addition, through the single-blade angle adjustment tool provided by the embodiment of the present application, the positions of the blade and the blade tip can be quickly adjusted before the single-blade hoisting.

[0075] The relative rotatable mode of the blade root relative to the blade root support body part 30 through the rotating part 31 has various modes. In some optional embodiments, the rotating part 31 comprises a plurality of rollers arranged at intervals on the blade root support body part 30, and the plurality of rollers constitute a support surface for supporting the blade root.

[0076] In these optional embodiments, the support surface formed by the plurality of rollers collectively supports the blade root, and the plurality of rollers can also provide a limit to the blade root to avoid the risk of falling off the support body part.

[0077] Optionally, the plurality of rollers are distributed at intervals along the outer contour of the blade root in the circumferential direction, so that the plurality of rollers can be enclosed to form a limiting space capable of providing a limit to the blade root. In other optional embodiments, the plurality of rollers can be divided into a plurality of groups arranged at intervals along the length direction of the blade, and each group of rollers is distributed at intervals along the outer contour of the blade root in the circumferential direction so that the plurality of rollers collectively support the blade root and improve the support force of the rollers.

[0078] Please refer to Figure 3 , Figure 3 is a structure schematic view of a blade root support assembly of a single-blade angle adjustment tool provided by the embodiment of the present application in another view.

[0079] As shown in Figure 3 , the installation mode of the rollers is various, and the rollers can be directly installed on a certain installation surface of the blade root support body 30. Alternatively, the blade root support body 30 comprises a connecting rod 301 and a support plate 302 connected between the connecting rod 301, and the support plate 302 is provided with an installation hole penetrating through the support plate 302, and the roller is rollably installed in the installation hole and extends out of the surface of the support plate 302 away from the support beam. Alternatively, when a plurality of rollers are distributed along the circumference of the blade root contour, a plurality of support plates 302 are also distributed along the circumference of the blade root contour, and each roller is arranged on each support plate 302.

[0080] In addition, in some optional embodiments, referring to Figure 3 and Figure 4 , a plurality of rollers are detachably installed on the support plate 302, so as to adapt to different blade root diameters, so that the tooling provided by the embodiment has wider applicability. And alternatively, an elastic layer is arranged outside the roller, and the elastic layer is, for example, a rubber structure, and the rubber structure is arranged around the roller. The elastic layer not only plays a role in preventing slipping, but also effectively protects the paint surface of the blade.

[0081] In some optional embodiments, the blade root support assembly 3 further comprises a first driving device for driving at least one of the plurality of rollers to rotate. By means of the first driving device, the roller can be driven to rotate actively. When the blade root is difficult to compensate for the position error of the blade root by following the rotation of the blade tip, the first driving device can be used to drive the roller to rotate, further adjust the position of the blade root, so that the blade root can quickly move to the target position. Alternatively, before the single-blade hoisting, the first driving device can be used to directly drive the roller to move the blade root to the target position.

[0082] Please continue to refer to Figure 4 , in some optional embodiments, the blade root support body 30 comprises a truss structure, and the truss structure comprises a plurality of connecting rods 301 connected to form a triangular truss unit. By connecting a plurality of connecting rods 301 to form a triangular truss unit, the stability of the blade root support body 30 structure can be effectively improved by using the stability of the triangle, and the weight of the blade root support body can be effectively reduced. Among them, the triangular truss unit refers to a unit enclosed by three connecting rods 301. Alternatively, a single connecting rod 301 can be used in two or more triangular truss units.

[0083] Please refer to Figure 5 , Figure 5 is a working schematic view of a blade tip support assembly of a single-blade angle adjusting tooling provided by the embodiment of the application.

[0084] As shown in Figure 5As shown, in some optional embodiments, the tip support assembly 2 comprises a first support 21, a second support 22, and a first connecting beam 23 hingedly connected between the first support 21 and the second support 22, which are arranged in parallel and support the tip fixing part 20.

[0085] The first support 21 comprises a first bracket 211 and a first base 212 arranged along the first direction X, and a first adjusting device 213 for adjusting the distance between the first bracket 211 and the first base 212; the first connecting beam 23 is hingedly connected to the first bracket 211, and the first base 212 and the first bracket 211 are connected to each other through the first adjusting device 213.

[0086] In these optional embodiments, the first base 212 and the first bracket 211 of the first support 21 are connected to each other through the first adjusting device 213, which can adjust the distance between the first base 212 and the first bracket 211, thereby adjusting the height of the first bracket 211. Since the first connecting beam 23 is in hinged connection with the first support 21 and the second support 22, the first connecting beam 23 can rotate relative to the first support 21 and the second support 22. When the first adjusting device 213 adjusts the distance between the first base 212 and the first bracket 211, the first connecting beam 23 simultaneously rotates relative to the first bracket 211, so that the first bracket 211 can be smoothly raised or lowered, and the end of the tip fixing part 20 corresponding to the first bracket 211 is raised or lowered, thereby adjusting the angle of the blade.

[0087] Optionally, as shown, Figure 5 The first support 21 and the second support 22 are arranged in parallel along the third direction Z, and when the first connecting beam 23 rotates relative to the first support 21 and the second support 22, the rotation angle of the tip relative to the axis AA of the blade itself can be adjusted.

[0088] Optionally, the tip support assembly 2 further comprises a second connecting beam 24, both ends of the second connecting beam 24 are hingedly connected to the first support 21 and the second support 22 respectively, the second connecting beam 24 is arranged side by side with the first connecting beam 23, and the first connecting beam 23, the first support 21, the second connecting beam 24 and the second support 22 form a parallelogram structure.

[0089] In these optional embodiments, the first connecting beam 23 and the second connecting beam 24 are parallel to each other, and the two ends of the first connecting beam 23 and the second connecting beam 24 can provide a limit to the first support 21 and the second support 22, avoiding the risk of tilting of the first support 21 and the second support 22 when the first connecting beam 23 and the second connecting beam 24 rotate relative to the first support 21 and the second support 22, and ensuring the stability of the blade during the entire lifting process.

[0090] Optionally, when the single-blade angle adjustment tool further comprises a second connecting beam 24, the second connecting beam 24 is hinged to the first bracket 211. When the first adjusting device 213 adjusts the distance between the first base 212 and the first bracket 211, the first connecting beam 23 and the second connecting beam 24 rotate relative to the first bracket 211 at the same time, which ensures the stability and enables the first bracket 211 to be smoothly raised or lowered, so that the end of the first bracket 211 is raised or lowered, and the angle of the blade can be adjusted.

[0091] The first adjusting device 213 can be a mechanical adjusting device, or the first adjusting device 213 can be an electrically controlled adjusting device such as a hydraulic cylinder or a pneumatic cylinder, which can realize stepless adjustment of the first adjusting device 213, and facilitate adjustment of the first bracket 211 to any height, thereby realizing any adjustment of the blade angle.

[0092] Please continue to refer to Figure 5 In some optional embodiments, the first adjusting device 213 comprises two second driving devices 213a, which are arranged side by side along the second direction Y and are respectively hinged to the two ends of the first bracket 211. Each second driving device 213a can adjust the distance between the first base 212 and the first bracket 211.

[0093] In these optional embodiments, the distance between the first base 212 and the first bracket 211 in the first direction X can be adjusted by the two second driving devices 213a respectively, so that the first bracket 211 is inclined relative to the second axis BB extending along the second direction Y. For example, when the extension sizes of the two second driving devices 213a in the first direction X are the same, the first bracket 211 is not inclined relative to the second axis BB, and when the extension sizes of the two second driving devices 213a in the first direction X are different, the second bracket 221 is inclined relative to the second axis BB.

[0094] The second driving device 213a can be arranged in various ways, for example, the second driving device 213a comprises a hydraulic cylinder which can be arranged in an extendable and retractable manner along the first direction X, and the two ends of the hydraulic cylinder are respectively connected to the first base 212 and the first bracket 211. The hydraulic cylinder can realize stepless adjustment and accurate adjustment of the blade angle. In other embodiments, the second driving device 213a can also be a motor and a gear rack transmission structure.

[0095] Please refer to Figure 5 on the basis of Figure 6 and Figure 7 , Figure 6 is Figure 5 a local enlarged structure diagram of II in Figure 7This is a schematic diagram of the structure of a limiting component of a single-blade angle adjustment tool provided in an embodiment of this application.

[0096] like Figures 5 to 7 As shown, in some optional embodiments, the first support 21 further includes a limiting member 214 disposed on the first base 212. The limiting member 214 includes two limiting portions 214a extending along the second direction Y, the two limiting portions 214a being spaced apart along the third direction Z. At least a portion of the first adjusting device 213 is located between the two limiting portions 214a to limit the range of motion of the first adjusting device 213 along the third direction Z. The limiting member 214 can provide a limit to the first adjusting device 213 in the third direction Z.

[0097] There are several ways to set the limiting member 214 on the first base 212. The limiting member 214 can be directly set on the first base 212, or the limiting member 214 can be indirectly set on the first base 212 through other components. As long as the limiting member 214 is set on the first base 212, the first base 212 can provide support to the limiting member 214.

[0098] Optionally, when the first adjustment device 213 includes two second drive devices 213a, at least a portion of the two second drive devices 213a are located between the two limiting members 214, so that the two limiting members 214 can simultaneously provide limiting in the third direction Z to the two second drive devices 213a.

[0099] Optionally, the limiting member 214 can limit the first adjusting device 213 during the assembly of the single-blade angle adjusting fixture. That is, the limiting member 214 is first installed on the first base 212, and then the first adjusting device 213 is installed between the two limiting members 214. After the first adjusting device 213 is installed, the limiting member 214 can be removed (for example, when the first adjusting device 213 consists of two hydraulic cylinders, the limiting member is removed after the hydraulic cylinders are installed. In this case, the limiting member 214 only provides a limiting function when the first adjusting device 213 is installed). Alternatively, the limiting member 214 can be retained after the first adjusting device 213 is installed. In this case, it can limit the first adjusting device 213 when the blade angle is adjusted using the fixture provided in this embodiment. That is, during the entire blade angle adjustment process, the limiting member 214 provides a limiting function to the first adjusting device 213 on the first base 212.

[0102] The first mating part 215 and the second mating part 216 can swing relative to each other in the second direction Y, thereby changing the height of both ends of the blade tip fixing part 20 in the second direction Y, and thus changing the angle between the blade tip and the second axis BB. When the blade tip fixing part 20 is fixed to the blade tip support assembly 2, and the blade tip is set on the blade tip fixing part 20, the first mating part 215 and the second mating part 216 can swing relative to each other under the action of the blade tip's gravity, realizing adaptive adjustment of the blade tip's center of gravity.

[0103] There are multiple ways in which the first mating part 215 and the second mating part 216 can swing relative to each other. For example, at least one of the contact surfaces of the first mating part 215 and the second mating part 216 that come into contact with each other is an arc surface, and the first mating part 215 and the second mating part 216 can swing relative to each other through the arc surface.

[0104] Optional, please refer to the following as well. Figure 8 and Figure 9 The single-blade angle adjustment fixture also includes a hinge part 217, which is hinged between the first mating part 215 and the second mating part 216 to prevent the first mating part 215 and the second mating part 216 from separating along the first direction X or misaligning along the third direction Z during mutual swinging.

[0105] In some alternative embodiments, the first mating portion 215 and the second mating portion 216 engage with each other along an arcuate trajectory. For example, the first mating portion 215 is provided with a plurality of first teeth distributed along a first arcuate trajectory, and the second mating portion 216 is provided with a plurality of second teeth distributed along a second arcuate trajectory. The first and second arcuate trajectories curve in opposite directions, and during the mutual swinging of the first mating portion 215 and the second mating portion 216, at least one first tooth is always engaged between two adjacent second teeth, or at least one second tooth is always engaged between two adjacent second teeth.

[0106] Optionally, during the blade hoisting process, the rotation angle of the blade relative to its own axis can be adjusted by adjusting the height of the first bracket 211 in the first support 21. That is, the rotation angle of the blade relative to its own axis can be adjusted by adjusting one of the first support 21 and the second support 22.

[0107] Please refer to Figure 8 and Figure 10 , Figure 10 is Figure 8 the structure diagram of the second support assembly of the middle blade tip (the upper part is not supported by the blade tip fixing part). In other optional embodiments, the second support 22 comprises a second bracket 221 arranged along the first direction X and a second base 222, wherein the first connecting beam 23 is hinged to the second bracket 221, the second base 222 and the second bracket 221 are connected to each other through a second adjusting device 223, and the second adjusting device 223 adjusts the distance between the second bracket 221 and the second base 222.

The first connecting beam 23 is hinged to the second bracket 221, and the first connecting beam 23 rotates relative to the second bracket 221 while the second adjusting device 223 adjusts the distance between the second bracket 221 and the second base 222, so that the second bracket 221 can be raised or lowered along the first direction X.

[0109] When the single-blade angle adjusting tool comprises the second connecting beam 24, the second connecting beam 24 is also hinged to the second bracket 221.

[0110] In the above embodiments, not only the rotation angle of the blade relative to the axis of the blade itself can be adjusted through the first adjusting device 213 and / or the second adjusting device 223, but also the height of the blade tip fixing part 20 can be adjusted through the simultaneous adjustment of the first adjusting device 213 and the second adjusting device 223, thereby adjusting the height of the blade tip and realizing the multi-dimensional adjustment of the position of the blade tip.

[0111] The second adjusting device 223 can be arranged in various ways, and optionally, the second adjusting device 223 can be arranged in the same way as the first adjusting device 213.

[0112] Please refer to Figure 10 and Figure 11 , Figure 11 is Figure 10 the structure diagram of the second adjusting device 223.

The second adjusting device 223 adopts a mechanical adjusting mode, which can reduce the manufacturing cost of the single-blade angle adjusting tool.

[0114] In the use process of the single-blade angle adjusting tool, the height of the second bracket 221 can be first adjusted through the second adjusting device 223. After the single-blade angle adjusting tool is assembled and the blade is located in the blade tip fixing part 20 which is supported on the blade tip support assembly 2, the angle of the blade relative to the second axis BB is adjusted through the first adjusting device 213.

[0115] Please continue to refer to Figure 10 In some optional embodiments, the single-blade angle adjusting tool further comprises a third matching part 224, and the second adjusting device 213 is connected to the first bracket 211 through the third matching part 224; the side of the first bracket 211 facing the third matching part 224 is provided with a fourth matching part 225, and the fourth matching part 225 abuts against the third matching part 224 in a manner that can swing relative to the second direction Y.

[0116] The third matching part 224 and the fourth matching part 225 can swing relative to the second direction Y, which can change the height of the two ends of the blade tip fixing part 20 in the second direction Y, and further change the included angle between the blade tip and the second axis BB. When the blade tip fixing part 20 is fixed on the blade tip support assembly 2, and the blade tip is arranged in the blade tip fixing part 20, under the action of the gravity of the blade tip, the third matching part 224 and the fourth matching part 225 can swing relative to each other, realizing self-adaptive adjustment of the gravity center of the blade tip.

[0117] The third matching part 224 and the fourth matching part 225 can swing relative to each other in various ways, for example, at least one of the contact surfaces of the third matching part 224 and the fourth matching part 225 abutting against each other is an arc surface, and the third matching part 224 and the fourth matching part 225 can swing relative to each other through the arc surface.

[0118] Optionally, the single-blade angle adjustment tool further comprises a hinge portion 217 hingedly connected between the third cooperating portion 224 and the fourth cooperating portion 225, so as to avoid the third cooperating portion 224 and the fourth cooperating portion 225 from separating along the first direction X or misaligning along the third direction Z during the swinging of the third cooperating portion 224 and the fourth cooperating portion 225 relative to each other.

[0119] In some alternative embodiments, the third cooperating portion 224 and the fourth cooperating portion 225 are both arranged along an arc-shaped trajectory. For example, the third cooperating portion 224 is provided with a plurality of first teeth arranged along a first arc-shaped trajectory, and the fourth cooperating portion 225 is provided with a plurality of second teeth arranged along a second arc-shaped trajectory. The first arc-shaped trajectory and the second arc-shaped trajectory are curved in opposite directions, and during the swinging of the third cooperating portion 224 and the fourth cooperating portion 225 relative to each other, there is always at least one first tooth engaged between two adjacent second teeth, or there is always at least one second tooth engaged between two adjacent first teeth.

[0120] The first cooperating portion 215 and the third cooperating portion 224, and the second cooperating portion 216 and the fourth cooperating portion 225 can be arranged in the same way or in different ways. In some alternative embodiments, the first cooperating portion 215, the second cooperating portion 216, the third cooperating portion 224 and the fourth cooperating portion 225 are all arc surfaces with the same curvature. The first cooperating portion 215 and the second cooperating portion 216 are curved in opposite directions, and the third cooperating portion 224 and the fourth cooperating portion 225 are curved in opposite directions. The four arc surfaces with the same curvature can reduce the difficulty of manufacturing and assembling the single-blade angle adjustment tool. During the lifting of the blade, the movements of the first cooperating portion 215 and the second cooperating portion 216, and the third cooperating portion 224 and the fourth cooperating portion 225 under the gravity of the blade tip are consistent, so as to adjust the angle between the blade tip and the second axis BB as a whole.

Arranging the adjusting beam 25 between the first base 212 and the second base 222, that is, arranging the adjusting beam 25 as close to the bottom as possible, can ensure the stability of the first support 21 and the second support 22.

[0123] Optionally, when the first support 21 is provided with both the limiting piece 214 and the adjusting beam 25, the limiting piece 214 can be detachably mounted on the adjusting beam 25 (that is, the limiting piece 214 can be indirectly arranged on the first base, as mentioned above). The adjusting beam 25 is formed in extension in the third direction Z, which can provide sufficient mounting space for the two limiting pieces 214 spaced apart in the third direction Z.

By movably arranging the overlapping part in the mounting groove 261, deformation of the blade tip fixing part 20 can be avoided during adjustment of the blade angle. It should be noted that the specific size of the mounting groove 261 is determined according to the maximum change value of the distance between the mounting grooves 261 on the first bracket 210 and the second bracket 220 in the Z direction during adjustment of the blade angle, so as to ensure that the blade tip fixing part 20 does not deform during adjustment of the blade angle and can be stably supported on the first bracket 210 and the second bracket 220.

[0132] Alternatively, the size of the mounting groove 261 in the second direction Y and / or in the third direction Z is greater than that of the overlapping part, so that the overlapping part can move in the mounting groove 261 along the second direction Y and / or in the third direction Z.

[0133] Alternatively, the overlapping part is rod-shaped and extends along the second direction Y. Two mounting grooves 261 are distributed along the second direction Y so that the two mounting grooves 261 can accommodate two ends of the overlapping part.

Each group of mounting grooves 261 is used to accommodate each overlapping part.

[0135] Please refer to Figure 10 Figure 16 , Figure 16 is Figure 8 the structural diagram of the first bracket.

[0136] Optionally, as shown in Figure 10 and Figure 16 , the tip support assembly 2 comprises a mounting plate 26, and a mounting groove 261 is formed in the mounting plate 26. The mounting plate 26 is in two groups, one group of mounting plates 26 is arranged on the first bracket 211, and the other group of mounting plates 26 is arranged on the second bracket 221.

[0137] Optionally, the two baffles 201 spaced apart along the second direction Y of the tip fixing part 20, when the lap joint part is located in the mounting groove 261, the mounting plate 26 is located between the two baffles 201, and the baffles 201 can provide limiting in the second direction Y to the mounting plate 26, so as to ensure the stability of the relative position between the tip fixing part 20 and the tip support assembly 2.

[0138] Next, taking the embodiment shown in Figure 1 as an example, the specific use method of the single-blade angle adjusting tool provided by the embodiment of the application and the technical effects thereof will be specifically described:

[0139] First, the relative positions of the blade root support assembly 3 and the tip support assembly 2 are determined according to the corresponding positions of the tip fixing part 20 on the tip, and the assembled tip support assembly 2 and blade root support assembly 3 are arranged at the preset positions.

[0140] Then, according to the height between the blade and the ground when the blade is hoisted, the distance between the second bracket 221 and the second base 222 is adjusted through the second adjusting device 223.

[0141] Next, the blade with the tip fixing part 20 can be placed on the blade root support assembly 3 and the tip support assembly 2. The tip on the tip fixing part 20 is located on the tip support assembly 2, and the blade root is supported by the rotating part 31 of the blade root support assembly 3. In this process, the first matching part 215 and the second matching part 216, the third matching part 224 and the fourth matching part 225 will swing relative to the second axis BB under the action of the gravity of the tip, which can adjust the angle of the tip relative to the second axis BB. In this process, the blade root can be followed by the rotating part 31, so as to avoid the influence of the relative rotation of the blade root and the tip on the service life of the blade.

[0142] ​Afterwards, the first bracket 211 can be driven to rise or fall as a whole by the two second driving devices 213a of the first adjusting device 213 at the same time, the parallelogram structure is deformed, the blade tip fixing part 20 is rotated relative to the blade axis, and then the blade tip is rotated relative to the blade axis, so that the blade reaches the target angle. In this process, the blade root can be rotated by the rotating part 31 to follow the blade tip, so as to avoid the relative rotation of the blade root and the blade tip affecting the service life of the blade.

[0143] Finally, by adjusting the two second driving devices 213a of the first adjusting device 213 respectively, the two second driving devices 213a are extended or retracted by different distances, and the first bracket 211 is deflected relative to the second axis BB. At this time, the first matching part 215 and the second matching part 216, the third matching part 224 and the fourth matching part 225 will swing with each other, until the blade is more accurately adjusted to the target angle. In addition, when the hoisting environment of the blade is poor, and the single-blade angle adjustment tool is located on uneven ground, by adjusting the two second driving devices 213a of the first adjusting device 213 respectively, the two second driving devices 213a are extended or retracted by different distances, so that the single-blade angle adjustment tool can adapt to the uneven ground.

[0144] The embodiment of the present application can not only realize multi-angle adjustment of the blade tip supporting assembly, but also make the blade root rotate with the blade tip during the adjustment process, which can not only improve the hoisting efficiency, but also reduce the stress of the blade during hoisting, and ensure the service life of the blade.

[0145] The tool of the single-blade angle adjustment tool provided by the embodiment of the present application can quickly and accurately adjust the blade to the preset position before hoisting the blade.

[0146] Although the present application has been described with reference to the preferred embodiments, various improvements can be made and equivalent replacements can be made to the components without departing from the scope of the present application. In particular, the technical features mentioned in each embodiment can be combined in any way as long as there is no structural conflict.
