[0044] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the known structures and technologies are not shown to avoid unnecessary ambiguity in the present application; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0045] The directional words appearing in the following description are all directions shown in the figures, and do not limit the lifting and flipping device and wind turbine generator set of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0046] In order to better understand this application, Figures 1 to 14 The lifting and flipping device and the wind turbine generator set according to the application embodiments are described in detail.

[0047] As the power and service life of wind turbines increase year by year, some parts need to be replaced or maintained, especially blades. Because blades are heavy and towers are high, large hoisting equipment is often used for operation. For offshore wind turbines, outrigger boats are needed for operation, which is costly and subject to environmental conditions. Therefore, a small crane can be installed on the nacelle to improve operation efficiency.

[0048] At present, in order to install a small crane on the nacelle, first, the crane is lifted from the ground to a corresponding height using a pulley, then the pulley is moved by an auxiliary crane, and after it is moved to the corresponding position, the pulley is fixed, and then the pulley is used to guide the crane to flip onto the nacelle, and finally, the crane is assembled to the nacelle. The process of moving the pulley is cumbersome, time-consuming and labor-intensive.

[0049] Based on the above defects, the embodiment of the present application provides a lifting and turning device 1, which is easy to operate and conducive to improving work efficiency. The lifting and turning device 1 can be produced and sold separately as an independent component. At the same time, it can also be used in wind turbines and as a component of wind turbines, which can shorten the construction period and reduce costs.

[0050] Please also read Figures 1 to 7 The embodiment of the present application provides a lifting and flipping device 1, which is used to lift and flip a crane 2 onto a nacelle 3 of a wind turbine generator set. The lifting and flipping device 1 includes a base 10 and a flipping component 20. The base 10 has a predetermined length in the first direction X. The flipping component 20 is arranged on the base 10, and the flipping component 20 includes a flipping bracket 21 and a pulley block 22. The flipping bracket 21 includes a driving frame 211 and a supporting frame 212. The driving frame 211 is provided with a connecting portion 2111 on one side of its own extension direction A and a hinged end 211a on the other side. The supporting frame 212 has a fixed end 212a, and the pulley block 22 is connected to the connecting portion 2111. The hinged end 211a is rotatably connected to the base 10, so that the flipping component 20 and the base 10 can switch between the first matching position S1 and the second matching position S2. In the first matching position S1, the hinged end 211a is connected to the base 10, the support frame 212 is connected to the drive frame 211, the fixed end 212a is supported on the base 10, and the extension direction A forms a first angle with the first direction X. In the second matching position S2, the hinged end 211a is connected to the base 10, and the extension direction A forms a second angle with the first direction X, which is smaller than the first angle.

[0051] The lifting and flipping device 1 provided in the embodiment of the present application sets the hinged end 211a to be rotatably connected to the base 10, so that the flipping component 20 and the base 10 can switch between the first matching position S1 and the second matching position S2. In the first matching position S1, the driving frame 211 is connected to the base 10 through the hinged end 211a, and the support frame 212 is supported on the base 10 through the fixed end 212a. The support frame 212 is connected to the driving frame 211, and the extension direction A of the driving frame 211 forms a first angle with the first direction X, so that the crane 2 can be lifted to the corresponding position through the pulley block 22. In the second matching position S2, the hinged end 211a is connected to the base 10, and the extension direction A forms a second angle smaller than the first angle with the first direction X, so that the pulley block 22 can be moved to the position where the crane 2 meets the flipping conditions. In this process, the position of the pulley block 22 can be moved without using external equipment, which is convenient to operate and helps to improve work efficiency.

[0052] In addition, the pulley block 22 is connected to the connecting portion 2111 on the driving frame 211, and the driving frame 211 can be rotatably connected to the base 10 through the hinged end 211a, so that the pulley block 22 can move with the rotation of the driving frame 211 without relying on the lifting of external equipment, which is beneficial to reducing the cost of equipment lifting, saving costs, and is easy to transport. It will not be restricted by environmental conditions and can be applied to various environments with strong versatility.

[0053] It is understandable that, in a specific implementation process, the lifting and flipping device 1 can be arranged on the nacelle 3 to lift and flip the crane 2 onto the nacelle 3 .

[0054] The base 10 extends along a first direction X and has a predetermined length. In the embodiment of the present application, the first direction X can be represented as the length direction of the base 10 , the second direction Y can be represented as the width direction of the base 10 , and the third direction Z can be represented as the height direction of the base 10 .

[0055] Depend on Figures 1 to 4 As shown, optionally, the base 10 can be connected to the cabin 3, and the base 10 extends out of the cabin 3 along the first direction X, and the flip bracket 21 is connected to the part of the base 10 extending out of the cabin 3, so that the pulley group 22 set on the flip bracket 21 can lift the crane 2 from the ground to the side of the cabin 3, so as to ensure the reliability and safety of the lifting and flipping device 1.

[0056] The flip component 20 is arranged on the base 10 and includes a flip bracket 21 and a pulley block 22. The flip bracket 21 is connected between the base 10 and the pulley block 22 to support the pulley block 22. The driving frame 211 connected to the pulley block 22 can be rotated through the hinge end 211a to move the pulley block 22 accordingly.

[0057] The pulley block 22 is used to connect and lift the crane 2. Optionally, the pulley block 22 is connected to the crane 2 via a rope 223, and the rope 223 can be set as a steel wire rope.

[0058] It is understandable that the pulley block 22 is connected to the connecting portion 2111 on one side of the driving frame 211 along the extension direction A. In the first matching position S1, the pulley block 22 is located as shown in FIG. Figure 1 Or Figure 5 In the position shown, in the third direction Z, the pulley block 22 and the base 10 are spaced apart. At this time, the crane 2 can be lifted to the side of the cabin 3 by the pulley block 22. In order to assemble the crane 2 to the cabin 3, the crane 2 needs to be turned over and moved to the corresponding position on the base 10. Then, the position of the pulley block 22 needs to be changed, and the hinge end 211a needs to be rotated so that the flipping component 20 and the base 10 are switched from the first matching position S1 to the second matching position S2. The pulley block 22 moves to the position as the driving frame 211 rotates. Figure 2 or Figure 4In the position shown in FIG. 1 , the pulley block 22 and the base 10 are located at approximately the same height. At this time, the crane 2 is ready for flipping. The pulley block 22 is used to lift the crane 2 and flip it onto the cabin 3. The positional relationship between the lifting and flipping device 1, the crane 2 and the cabin 3 can be obtained by Figure 3 shown.

[0059] The flipping component 20 includes a driving frame 211 and a supporting frame 212. The driving frame 211 is provided with a connecting portion 2111 connected to the pulley group 22. The supporting frame 212 can be used to support the driving frame 211. Optionally, the extension direction of the supporting frame 212 is the same as the third direction Z, so that when it is in the first matching position S1, the supporting frame 212 has a better supporting effect, which is beneficial to improving the reliability of the lifting and flipping device 1.

[0060] Optionally, the connecting portion 2111 may be a part of the driving frame 211 to facilitate detachable connection with the pulley block 22. Of course, the connecting portion 2111 may also be configured as a structure such as an ear plate protruding from the driving frame 211 to facilitate detachable connection with the pulley block 22.

[0061] Furthermore, configuring the flip bracket 21 to have a driving frame 211 and a supporting frame 212 can reduce the weight of the flip component 20 and help ensure the effectiveness of the flip component 20 and the base 10 being able to switch between the first matching position S1 and the second matching position S2.

[0062] In the first matching position S1 , the hinged end 211 a is connected to the base 10 , the fixed end 212 a is supported on the base 10 , the support frame 212 is connected to the driving frame 211 , and the extending direction A and the first direction X form a first angle.

[0063] Optionally, the support frame 212 has a fixed end 212a on one side along its extension direction, and the other side is used to connect to the driving frame 211. In the first matching position S1, the hinged end 211a and the fixed end 212a are arranged in the first direction X at intervals.

[0064] Optionally, the first angle can be set to between 100° and 150°, so that the driving frame 211 can be tilted on the base 10, and the driving frame 211 and the supporting frame 212 jointly support the pulley block 22 to better provide support force, so as to meet the requirement that the pulley block 22 can lift the crane 2 from the bottom surface to the side of the cabin 3. Exemplarily, the first angle can be set to 120°, and the angle between the extension direction of the supporting frame 212 and the first direction X is 90°, which is conducive to improving the stability of the flip bracket 21.

[0065] Among them, the fixed end 212a is supported on the base 10, which can be understood as the fixed end 212a can be supported against the base 10, that is, the fixed end 212a is the side of the support frame 212 away from the pulley block 22 along its own extension direction. In the first matching position S1, the pressure of the pulley block 22 can satisfy the support frame 212 to directly support against the base 10. Of course, the fixed end 212a can also be set as a structure that is detachably connected to the base 10, and this application is not limited to this.

[0066] In the second matching position S2, the hinge end 211a is connected to the base 10, and the extending direction A and the first direction X form a second angle, which is smaller than the first angle.

[0067] Optionally, the second angle can be set to between -5° and 5°, so that the extension direction A of the driving frame 211 is approximately parallel to the first direction X, that is, the pulley block 22 is parallel to the base 10, and the pulley block 22 moves to a position close to the base 10, so that the crane 2 has a flipping condition, and the pulley block 22 continues to lift the crane 2 to flip it onto the cabin 3. Exemplarily, the second angle is 0°, so that the pulley block 22 can better lift the crane 2 onto the cabin 3.

[0068] Optionally, the hinged end 211a of the flip component 20 can rotate about the second direction Y, so that in the first matching position S1, the driving frame 211 is located on one side of the base 10 along the first direction X, and in the second matching position S2, the driving frame 211 rotates to the other side of the base 10 along the first direction X. This arrangement is used to ensure the effectiveness of the pulley group 22 moving from a position spaced apart from the base 10 to the base 10.

[0069] In addition, the pulley block 22 is connected to the driving frame 211. In the second matching position S2, the driving frame 211 can serve as a part of the fixed support of the pulley block 22, which is beneficial to improve the force transmission effect of the pulley block 22, so as to better lift the crane 2 to the cabin 3.

[0070] Specifically, when the lifting and flipping device 1 provided in the embodiment of the present application is in use, the base 10 is connected to the cabin 3 so that the lifting and flipping device 1 is set on the cabin 3, and the base 10 and the flipping component 20 are in the first matching position S1, and the pulley block 22 is located on the side close to the crane 2, the pulley block 22 and the crane 2 are connected by a rope 223, and the rope 233 is wound to lift the crane 2 from the ground to the side of the cabin 3. At this time, the control hinge end 211a is rotated and connected to the base 10 so that the flipping component 20 and the base 10 are switched from the first matching position S1 to the second matching position S2, so as to adjust the path of the rope 223 connecting the pulley block 22 and the crane 2, and tighten the rope 223 wound between the pulley block 22 and the crane 2, and the crane 2 is pulled and flipped onto the cabin 3 by the rope 223.

[0071] During the switching of the flip component 20 and the base 10 between the first matching position S1 and the second matching position S2, there is no need to remove the load on the pulley block 22, that is, there is no need to detach the rope 223 connecting the pulley block 22 and the crane 2. Of course, there is no need to detach the crane 2, which is beneficial to improve safety.

[0072] In addition, the pulley block 22 is always arranged on the connecting portion 2111 of the driving frame 211. There is no need to remove the pulley block 22 from the driving frame 211 when the position is moved, which is conducive to maintaining the posture of the pulley block 22 during the movement and preventing the rope 223 from being detached, saving operation time, reducing operation difficulty, and improving operation efficiency.

[0073] Optionally, the crane 2 is further provided with a telescopic cylinder to flip the crane 2 onto the cabin 3 together with the rope 223 wound around the pulley block 22 in the second matching position S2.

[0074] See also Figure 1 , Figure 2 as well as Figure 8 As an optional implementation, the support frame 212 is fixedly connected to one side of the driving frame 211 along the extension direction A close to the connecting portion 2111 , and at the second matching position S2 , the fixed end 212 a is separated from the base 10 .

[0075] By configuring in this manner, it is possible to avoid interference between the crane 2 and the support frame 212 during the lifting and flipping process, thereby ensuring the reliability of the lifting and flipping device 1.

[0076] When the driving frame 211 is rotatably connected to the base 10 via the hinged end 211 a , the support frame 212 can rotate together with the driving frame 211 , so that the fixed end 212 a of the support frame 212 is separated from the base 10 at the second matching position S2 .

[0077] Optionally, the drive frame 211 and the support frame 212 can be set as an integral structure to improve processing efficiency. Of course, the drive frame 211 and the support frame 212 can also be provided separately and connected into a whole by a fixed connection method such as welding or gluing, which is conducive to reducing processing difficulty and improving use flexibility.

[0078] By connecting the support frame 212 to the side of the driving frame 211 along the extension direction A close to the connecting portion 2111, interference with the pulley block 22 on the connecting portion 2111 can be avoided, and the support frame 212 can also better provide supporting force for the driving frame 211.

[0079] See also Figure 1 , Figure 4 , Figure 6 and Figure 7As an optional implementation, the driving frame 211 is provided with a first docking portion 2112 on one side close to the connecting portion 2111 along the extension direction A, and the supporting frame 212 is provided with a second docking portion 2121. In the first matching position S1, the first docking portion 2112 is connected to the second docking portion 2121. In the second matching position S2, the first docking portion 2112 and the second docking portion 2121 are separately provided, and the fixed end 212a is supported on the base 10.

[0080] By configuring in this manner, the weight of the flip bracket 21 during rotation can be reduced, thereby reducing the difficulty of operation and ensuring safety.

[0081] Specifically, in the first mating position S1, the first docking portion 2112 is first separated from the second docking portion 2121, and then the hinged end 211a and the base 10 are driven to rotate so that the driving frame 211 rotates accordingly, and the support frame 212 maintains the initial position, so that in the second mating position S2, the support frame 212 is still supported on the base 10 by the fixed end 212a.

[0082] Optionally, the first docking portion 2112 and the second docking portion 2121 may be detachably connected by fasteners such as bolts, studs and screws, and of course, may also be connected by a hinge.

[0083] Optionally, the first docking portion 2112 is disposed on one side of the driving frame 211 close to the connecting portion 2111 along the extension direction A to avoid interference with the pulley block 22 connected to the connecting portion 2111.

[0114] Optionally, the limiting cavity 2111a may be a through hole provided in the connecting portion 2111, or may be a groove provided on the connecting portion 2111, and the first adapter portion 2211 may pass through the limiting cavity 2111a to be connected to the connecting portion 2111, thereby facilitating the improvement of the connection strength between the pulley block 22 and the driving frame 211, and preventing the pulley block 22 and the driving frame 211 from separating during the process of position movement, thereby facilitating the improvement of the safety and reliability of the lifting and flipping device 1.

[0115] Optionally, the first transition portion 2211 has a shoulder structure so that it can pass through the limiting cavity 2111a and be clamped on the connecting portion 2111 to prevent separation.

[0117] This arrangement helps to improve the connection stability between the pulley block 22 and the connecting portion 2111, prevents the pulley block 22 from being separated from the connecting portion 2111 during movement, and helps to improve safety.

[0118] Furthermore, by providing the limiting member 214, the assembly and disassembly of the pulley block 22 and the flip bracket 21 are facilitated, which helps to improve the working efficiency.

[0119] The pulley block 22 can be connected to the flip bracket 21 through the first connecting portion 2111.

[0120] As an optional implementation, a second adapter portion 2212 is provided on one side of the connecting seat 221 along its thickness direction. At the second matching position S2 , the pulley block 22 is connected to the base 10 via the second adapter portion 2212 .

It can be understood that when the pulley block 22 is located in the position as shown in FIG. Figure 2 as well as Figure 4 When the crane 2 is in the position shown, the crane 2 is ready for flipping, and the pulley block 22 continues to pull the crane 2. As the crane 2 flips, the path of the rope 223 on the pulley 222 connected to the crane 2 also changes.

[0130] Exemplarily, when the tension value detected by the first sensor 41 does not exceed the set value, the driving member 31 continues to drive the driving frame 211 to rotate. When the tension value detected by the first sensor 41 exceeds the set value, the driving frame 211 stops rotating to prevent the driving member 31 from being overloaded and the rope 223 on the pulley block 22 from being detached, which is beneficial to ensure the safety and reliability of the lifting and flipping device 1.

[0131] Optionally, the first sensor 41 can be set as a pin-type tension sensor. Optionally, the number of the first sensor 41 can be set to one, which is installed on the rotating shaft 2221 of one of the pulleys 222, which is conducive to reducing costs.

[0133] By setting up the second sensor 42, the angle value between the driving frame 211 and the base 10 can be measured in real time, and the matching position relationship between the flip component 20 and the base 10 can be fed back according to the measured angle value, and it can be determined whether the flipping conditions of the crane 2 are met.

[0134] Exemplarily, when the angle value measured by the second sensor 42 is 0°, that is, the flip component 20 and the base 10 are located at the second matching position S2, at this time, the flipping condition of the crane 2 is met, and the flipping operation of the crane 2 can be performed. If the angle value measured by the second sensor 42 is not 0°, that is, the flip component 20 and the base 10 are not at the second matching position S2, at this time, the crane 2 does not meet the flipping condition, and the hinged end 211a of the driving frame 211 can continue to be controlled to rotate and connect with the base 10, so that the flip component 20 and the base 10 are adjusted to the second matching position S2.

[0135] Optionally, the second sensor 42 is disposed on the driving frame 211 and is disposed on the side of the driving frame 211 along the extension direction A close to the hinge end 211 a to ensure the accuracy of the data measured by the second sensor 42 .

[0139] Exemplarily, when the acceleration value detected by the third sensor 43 and the minimum distance value between the crane 2 and the flip bracket 21 meet the requirement that the crane 2 is lifted to the side position of the cabin 2 , the driving member 31 drives the driving frame 211 to rotate.

[0140] Optionally, the third sensor 43 can be set on the connecting frame 213 and on the side of the connecting frame 213 close to the supporting frame 212 along the first direction X.
