Technical Field

[0001] This application relates to the field of wind power technology, and in particular to a lifting device. Background Technology

[0002] In the wind power industry, improvements are needed in product performance, price, service, and innovation to enhance the competitiveness of wind power products. As a crucial part of project delivery, tooling and hoisting equipment require design optimization and technological innovation.

[0003] For wind turbine generator sets, different platforms require different lifting tools, which are not interchangeable. Furthermore, with the rapid pace of market development, the original lifting tools become unusable on newer wind turbine generator sets, resulting in significant waste of lifting equipment. Additionally, even within the same wind turbine generator set, there are different components to be lifted. These components have different configurations and center of gravity parameters, thus requiring specialized lifting tools with different structures. This leads to an excessive variety of lifting tools, necessitating frequent searching and replacement of tools during on-site lifting, reducing lifting efficiency. Utility Model Content

[0004] This application provides a lifting tool that enables the use of various lifting components and lifting tools under different lifting conditions, thereby reducing the amount of lifting materials and improving lifting efficiency.

[0005] On one hand, according to the embodiments of this application, a lifting device is proposed, which includes a lifting frame, a lifting base assembly, an adjusting assembly, and a lifting assembly. The lifting base assembly is connected to the lifting frame, and there are multiple lifting base assemblies. The multiple lifting base assemblies include a first lifting base assembly and a second lifting base assembly that are spaced apart along a first direction. The adjusting assembly is connected to the lifting frame and is adjustable at the connection position of the lifting frame along the first direction. The lifting assembly includes a first sling and a second sling. The first sling is connected to the first lifting base assembly, and the second sling is wound around the second lifting base assembly and connected to the adjusting assembly.

[0006] According to one aspect of the embodiments of this application, along a first direction, at least one of the first hanger assembly and the second hanger assembly is adjustable in the connection position of the hanger.

[0007] According to one aspect of the present application, a plurality of first connecting holes are provided at intervals along a first direction on the hanger, and the hanger assembly includes a hanger body and a first connector. The hanger body has an installation hole, and the first connector passes through the first connecting hole and the installation hole of the hanger body to fix the hanger body to the hanger.

[0008] According to one aspect of the embodiments of this application, the hanger includes a plurality of hanger plates arranged in parallel, and the hanger body includes a multi-layer frame body connected to each other. The frame body is respectively sleeved on the outer periphery of the hanger plate and has a degree of freedom of movement relative to the hanger plate in a first direction. The multi-layer frame body is provided with mounting holes, and a first connector passes through the first connecting hole and the mounting holes of each layer frame body.

[0009] According to one aspect of the embodiments of this application, the first sling is configured as a loop structure, the first sling extends into the gap between two adjacent frames of the first sling assembly and is sleeved on the first connector.

[0010] According to one aspect of the embodiments of this application, the adjustment assembly includes an adjustment body and a second connecting member. The structure of the adjustment body is the same as that of the hanger body. The second connecting member passes through a first connecting hole and a mounting hole of the adjustment body to fix the adjustment body to the hanger. The second sling is configured as a loop structure, and the second sling is wound around the first connecting member of the second hanger assembly and sleeved on the second connecting member of the adjustment assembly.

[0011] According to one aspect of the embodiments of this application, the lifting device further includes a counterweight assembly connected to the hanger to balance the hanger.

[0012] According to one aspect of the present application, the hanger is provided with scale markings at intervals along a first direction, and the scale markings are configured to indicate the position information of the hanger assembly and the adjustment assembly along the first direction on the hanger.

[0013] According to one aspect of the embodiments of this application, the lifting bracket assembly includes a lifting member disposed along a second direction on the side of the lifting bracket assembly opposite to the lifting assembly and used to connect to the component to be lifted. The length of the lifting member of at least one lifting bracket assembly along the second direction is adjustable, and the second direction intersects with the first direction.

[0014] According to one aspect of the embodiments of this application, the lifting member includes an adapter, a third connector, and a third sling. The adapter has a plurality of second connection holes along a second direction, and the third sling is connected to the second connection holes through the third connector.

[0015] The lifting device provided in this application embodiment can connect multiple lifting base assemblies to the lifting points of the component to be lifted during the lifting of the component. These assemblies are then connected to a lifting assembly via a crane, which raises the lifting frame to lift the component. Since different components have different center of gravity parameters, after connecting the lifting points of the component to the first and second lifting base assemblies on the lifting frame, the position of the adjusting assembly on the lifting frame can be adjusted according to the center of gravity of the component. This ensures that after the first sling of the lifting assembly is connected to the first lifting base assembly, and the second sling is wound around the second lifting base assembly and connected to the adjusting assembly, the lifting position of the lifting assembly and the center of gravity of the component are on the same vertical line. This design is suitable for lifting various components under different lifting conditions, achieving versatility and lightweight design of the lifting device, reducing costs, and improving lifting efficiency.

Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples. In the accompanying drawings and the following description, at least some well-known structures and techniques are not shown to avoid unnecessarily obscuring the application; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.

[0032] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the lifting device of this application. It should also be noted in the description of this application that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] To better understand this application, the lifting devices of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0034] Please refer to the following: Figures 1 to 3 , Figure 1 The following are schematic diagrams of the lifting device in some embodiments of this application. Figure 2 The image shows a front view of a lifting device in some embodiments of this application. Figure 3 Partial cross-sectional views of the lifting devices provided in some embodiments of this application are shown.

[0035] According to an embodiment of this application, a lifting device 10 is provided. The lifting device 10 includes a lifting frame 1, a lifting seat assembly 2, an adjusting assembly 3, and a lifting assembly 4. The lifting seat assembly 2 is connected to the lifting frame 1. There are multiple lifting seat assemblies 2. The multiple lifting seat assemblies 2 include a first lifting seat assembly 2a and a second lifting seat assembly 2b that are spaced apart along a first direction X. The adjusting assembly 3 is connected to the lifting frame 1 and is adjustable along the first direction X at the connection position of the lifting frame 1. The lifting assembly 4 includes a first sling 41 and a second sling 42. The first sling 41 is connected to the first lifting seat assembly 2a, and the second sling 42 is wound around the second lifting seat assembly 2b and connected to the adjusting assembly 3.

[0036] In this embodiment, the lifting device 10 can connect multiple lifting base assemblies 2 to the lifting points of the component to be lifted, and connect them to the lifting assembly 4 via a crane, thereby raising the lifting frame 1 to lift the component. Since different components have different center of gravity parameters, after connecting the lifting points of the component to the first lifting base assembly 2a and the second lifting base assembly 2b on the lifting frame 1, the position of the adjusting assembly 3 on the lifting frame 1 can be adjusted according to the center of gravity position of the component. This ensures that after the first sling 41 of the lifting assembly 4 is connected to the first lifting base assembly 2a, and the second sling 42 is wound around the second lifting base assembly 2b and connected to the adjusting assembly 3, the lifting position of the lifting assembly 4 and the center of gravity position of the component to be lifted are on the same vertical line. This allows for stable lifting of various components and under different lifting conditions, achieving the versatility and lightweight design of the lifting device 10, reducing costs, and improving lifting efficiency.

[0037] The first sling 41 and the second sling 42 each include a lifting end and a load end. The lifting ends of the first sling 41 and the second sling 42 are intersected and used to connect to the crane. The lifting position of the lifting assembly 4 refers to the location of the lifting ends of the first sling 41 and the second sling 42.

[0038] Optionally, the lifting ends of the first sling 41 and the second sling 42 can be directly connected to the crane. Alternatively, the lifting assembly 4 may also include a lifting member 43, where the lifting ends of the first sling 41 and the second sling 42 can be located on the lifting member 43. The crane is connected to the lifting member 43 and can lift the first sling 41 and the second sling 42 through the lifting member 43.

[0039] As an optional implementation, the lifting component 43 may include a lifting body 431 and an adapter sling 432. The lifting ends of the first sling 41 and the second sling 42 are connected to the lifting body 431, and the adapter sling 432 is disposed on the lifting body 431 and used to connect to the hook of the crane. Optionally, the lifting body 431 may be configured as a triangular plate, with its corners connected to the lifting ends of the first sling 41, the second sling 42, and the adapter sling 432, respectively, to distribute the force on the lifting component 43, resist deformation of the lifting component 43, and improve the structural stability of the lifting component 43 under load.

[0040] The load end of the first sling 41 is connected to the first sling assembly 2a, and the load end of the second sling 42 is wound around the second sling assembly 2b and connected to the adjusting assembly 3. That is, the second sling 42 can be divided into a first sling segment 421 and a second sling segment 422 according to the second sling assembly 2b. The first sling segment 421 is located between the lifting end of the first sling 41 and the second sling assembly 2b, and the second sling segment 422 is located between the second sling assembly 2b and the adjusting assembly 3.

[0041] It is understandable that the lifting ends of the first sling 41 and the second sling 42 are determined by the relative length between the first sling segments 421 of the first sling 41 and the second sling 42. Therefore, by adjusting the position of the adjusting component 3 along the first direction X, the length of the first sling segment 421 can be adjusted so that the lifting position of the lifting component 4 and the center of gravity of the component to be lifted are on the same vertical line. This avoids the uneven force on the first sling 41 and the second sling 42 due to different bearing angles, which would cause the component to be lifted to tilt, and achieves stable lifting of the component to be lifted.

[0042] For the lifting device 10 in this application embodiment, when lifting wind turbine generator sets on different platforms, different components to be lifted from the same wind turbine generator set (tower, nacelle, drive chain, hub, and blades, etc.), or different derivative configurations of the same component to be lifted, the lifting seat assembly 2 on the lifting device 10 can be connected to each lifting point on the component to be lifted. The position of the adjustment assembly 3 can be adjusted according to the center of gravity of the component to be lifted so that the lifting position of the lifting assembly 4 is on the same vertical line as the center of gravity of the component to be lifted. Thus, the lifting device 10 can be used to lift wind turbine generator sets on different platforms, different components to be lifted from wind turbine generator sets, and different derivative configurations of the same component to be lifted. This achieves the versatility and lightweight design of the lifting device 10, reduces the number of lifting devices 10 required, and eliminates the need for frequent searching and replacement of the lifting device 10 during on-site lifting, thereby improving lifting efficiency.

[0043] To further improve the versatility of the components to be lifted, in some optional embodiments, the number of lifting base assemblies 2 of the lifting device 10 can be greater than the number of lifting points of the components to be lifted (not shown in the figure). Multiple lifting base assemblies 2 are spaced apart on the lifting frame 1 along the first direction X. Therefore, when lifting different components to be lifted, each lifting point on the component to be lifted can be connected to the corresponding part of the lifting base assembly 2 on the lifting device 10 according to the position of each lifting point on the component to be lifted along the first direction X. The lifting base assembly 2 connected to the component to be lifted can be used as the first lifting base assembly 2a and the second lifting base assembly 2b. By connecting the lifting assembly 4 to the lifting base assembly 2, reliable lifting of different components to be lifted can be achieved.

[0044] Please see Figures 1 to 3 In some alternative embodiments, at least one of the first hanger assembly 2a and the second hanger assembly 2b is adjustable in the connection position of the hanger 1 along the first direction X.

[0045] In addition to increasing the number of lifting bracket assemblies 2, at least one of the first lifting bracket assembly 2a and the second lifting bracket assembly 2b can be adjusted in the connection position of the lifting frame 1. When lifting different components, the connection position of at least one of the first lifting bracket assembly 2a and the second lifting bracket assembly 2b in the lifting frame 1 can be adjusted according to the position of each lifting point on the component to be lifted along the first direction X, so that each lifting point on the component to be lifted can be connected to the corresponding part of the lifting bracket assembly 2 on the lifting device 10, thereby achieving a reliable connection of each component to be lifted.

[0046] Optionally, at least one of the first hanger assembly 2a and the second hanger assembly 2b may be adjustable in the connection position of the hanger 1. This could be that the first hanger assembly 2a is adjustable in the connection position of the hanger 1 while the second hanger assembly 2b is fixed in the connection position of the hanger 1, or the second hanger assembly 2b is adjustable in the connection position of the hanger 1 while the first hanger assembly 2a is fixed in the connection position of the hanger 1, or at least one of the first hanger assembly 2a and the second hanger assembly 2b may be adjustable in the connection position of the hanger 1.

[0047] It is understandable that the above-described method, which makes at least one of the first and second lifting bracket assemblies 2a and 2b adjustable in the connection position of the lifting frame 1, can reduce the number of lifting bracket assemblies 2, reduce costs, and lighten the weight of the lifting device 10, thereby achieving the versatility and lightweight design of the lifting device 10.

[0048] In order to make at least one of the first hanger assembly 2a and the second hanger assembly 2b adjustable in the connection position of the hanger 1, as an optional embodiment, the hanger 1 is provided with a plurality of first connection holes 111 at intervals along the first direction X. The hanger assembly 2 includes a hanger body 21 and a first connector 22. The hanger body 21 has a mounting hole. The first connector 22 passes through the first connection hole 111 and the mounting hole of the hanger body 21 to fix the hanger body 21 to the hanger 1.

[0049] For ease of description, the mounting hole of the hanger body 21 is defined as the first mounting hole.

[0050] By providing multiple first connecting holes 111 at intervals along the first direction X on the hanger 1, the first connecting member 22 can be inserted through one of the first connecting holes 111 on the hanger 1 and the first mounting hole of the hanger body 21 according to the position of each lifting point on the component to be lifted along the first direction X, so as to fix the hanger assembly 2 at the designated position of the hanger 1 and adapt it to the lifting of the component to be lifted.

[0051] Optionally, multiple first connection holes 111 are arranged at equal intervals along the first direction X to simplify the structure of the lifting device 10 and improve adjustment efficiency.

[0052] It is understandable that the spacing between two adjacent first connecting parts 22 and the position of each first connecting hole 111 can be adjusted according to the actual load-bearing requirements of the component to be lifted and the lifting device 10, so as to improve the load-bearing capacity of the lifting device 10 while meeting the general requirements of lifting different components to be lifted, so as to achieve reliable lifting of each component to be lifted.

[0053] Please refer to the following: Figures 1 to 5 , Figure 4 The present application shows a schematic diagram of the structure of the hanger 1 provided in some embodiments. Figure 5 It shows Figure 1 Enlarged view of point A in the middle.

[0054] In some optional embodiments, the hanger 1 includes a plurality of hanger plates 11 arranged in parallel, and the hanger body 21 includes a multi-layer frame 211 connected to each other. The frame 211 is respectively sleeved on the outer periphery of the hanger plate 11 and has a degree of freedom of movement relative to the hanger plate 11 in the first direction X. The multi-layer frame 211 is provided with a first mounting hole, and the first connector 22 passes through the first connecting hole 111 and the first mounting hole of each layer frame 211.

[0055] By having the frame 211 respectively fitted onto the outer periphery of the hanger plate 11 and having a degree of freedom of movement relative to the hanger plate 11 along the first direction X, when adjusting the connection position of the hanger body 21 along the first direction X on the hanger 1, the hanger body 21 can be controlled to move relative to the hanger plate 11 along the first direction X, and after moving to the preset position, the first connector 22 is inserted into the first connection hole 111 and the first mounting hole of each layer of frame 211, thereby fixing the position of the hanger assembly 2. The above adjustment method is simpler and less labor-intensive, and effectively improves the adjustment efficiency.

[0056] As an optional implementation, there are two hanger plates 11, and the hanger body 21 includes two connected frames 211, which are respectively sleeved on the outer periphery of the hanger plate 11. This is to ensure the reliability of the hanger body 21 moving relative to the hanger plate 11 in the first direction X while reducing the manufacturing precision of the hanger 1 and the hanger assembly 2.

[0057] Optionally, the first connector 22 can be configured as a pin, and the hanger assembly 2 further includes a shaft end clamping plate. The shaft end clamping plate is used to clamp the pin after the pin passes through the first connecting hole 111 and the first mounting hole of each layer frame 211, so as to limit the degree of freedom of the pin to detach from the hanger body 21, thereby reliably fixing the hanger body 21 to the preset position of the hanger 1 and improving the reliability of the connection.

[0058] Optionally, the hanger 1 may also include support legs 12, which support multiple parallel hanger plates 11 to effectively support the hanger plates 11 when handling or installing the lifting device 10, making it easier to store the hanger 1.

[0059] In some alternative embodiments, the first sling 41 is configured as a loop structure, the first sling 41 extends into the gap between two adjacent frames 211 of the first sling assembly 2a and is sleeved on the first connector 22.

[0060] Regarding the aforementioned lifting seat assembly 2, the first sling 41 can be configured as a loop structure, that is, the first sling 41 is bent and connected to form a closed loop structure. By having the load end of the first sling 41 extend into the gap between two adjacent frames 211 of the first lifting seat assembly 2a and sleeved on the first connector 22, it is easier to connect the first sling 41 to the first lifting seat assembly 2a, and the risk of the first sling 41 detaching from the first lifting seat assembly 2a is reduced, thus improving the reliability of the connection. Furthermore, for the first sling 41 itself, due to its loop structure, the force borne by the first sling 41 can be better distributed, improving the load-bearing capacity of the first sling 41 and enhancing the reliability and stability of the lifting device 10.

[0061] Similar to the hanger assembly 2, in some optional embodiments, the adjustment assembly 3 includes an adjustment body 31 and a second connector 32. The structure of the adjustment body 31 is the same as that of the hanger body 21. The second connector 32 passes through the first connection hole 111 and the mounting hole of the adjustment body 31 to fix the adjustment body 31 to the hanger 1. The second sling 42 is configured as a loop structure, and the second sling 42 is wound around the first connector 22 of the second hanger assembly 2b and sleeved on the second connector 32 of the adjustment assembly 3.

[0062] For ease of description, the mounting hole of the adjusting body 31 is defined as the second mounting hole.

[0063] The fact that the structure of the adjusting body 31 is the same as that of the hanging base body 21 means that the adjusting body 31 also includes connected multi-layered frames 211. Each frame 211 of the adjusting body 31 is correspondingly sleeved on the outer periphery of the hanging bracket plate 11 and has a degree of freedom of movement along the first direction X relative to the hanging bracket plate 11. The multi-layered frames 211 of the adjusting body 31 are correspondingly provided with second mounting holes. By making the structure of the adjusting body 31 the same as that of the hanging base body 21, the first connecting hole 111 on the hanging bracket 1 can be reused to adjust the connection position of the adjusting component 3 along the first direction X on the hanging bracket 1, simplifying the structure of the lifting device 10 and making the manufacturing of the lifting device 10 easier.

[0064] Furthermore, when the structure of the adjusting body 31 is the same as that of the lifting seat body 21, the second sling 42 can also be configured as a loop structure, that is, the second sling 42 is bent and connected to form a closed loop structure. By having the second sling 42 wrapped around the first connecting member 22 of the second lifting seat assembly 2b and its load end sleeved on the second connecting member 32 of the adjusting assembly 3, it is easier to connect the second sling 42 to the adjusting assembly 3, and the risk of the first sling 41 detaching from the adjusting assembly 3 is reduced, thus improving the reliability of the connection. Moreover, for the second sling 42 itself, since it forms a loop structure, the force borne by the second sling 42 can be better distributed, improving the load-bearing capacity of the second sling 42 and improving the reliability and stability of the lifting device 10.

[0065] Please see Figures 1 to 5 In some alternative embodiments, the lifting device 10 further includes a counterweight assembly 5 connected to the hanger 1 for balancing the hanger 1.

[0066] It is understood that the counterweight component 5 can balance the hanger 1 in a weight-adjustable manner, and / or the counterweight component 5 can also be set to be adjustable along the first direction X at the connection position of the hanger 1, so as to adjust the weight of the counterweight component 5 and / or the position of the counterweight component 5 according to the position of the first hanger component 2a and the second hanger component 2b, so as to achieve the balancing of the hanger 1 and more reliably realize the universal lifting of different components to be lifted and under different working conditions.

[0067] As an optional implementation, the counterweight assembly 5 includes a counterweight body 51, a fourth connector 52, and a counterweight component 53 connected to the counterweight body 51. The structure of the counterweight body 51 can be the same as that of the hanger body 21, that is, the counterweight body 51 also includes connected multi-layer frames 211. Each frame 211 of the counterweight body 51 is correspondingly sleeved on the outer periphery of the hanger plate 11 and has a degree of freedom of movement relative to the hanger plate 11 along the first direction X. The multi-layer frames 211 of the counterweight body 51 are correspondingly provided with third mounting holes. By making the structure of the counterweight body 51 the same as that of the hanger body 21, the first connecting hole 111 on the hanger 1 can be reused to adjust the connection position of the counterweight assembly 5 along the first direction X on the hanger 1, simplifying the structure of the lifting device 10 and making the manufacturing of the lifting device 10 easier.

[0068] To facilitate the adjustment of the connection positions of the hanging bracket assembly 2, the adjusting assembly 3, and the counterweight assembly 5 along the first direction X on the hanger 1, in some optional embodiments, the hanger 1 is provided with scale markings 13 at intervals along the first direction X. The scale markings 13 are configured to indicate the position information of the hanging bracket assembly 2 and the adjusting assembly 3 along the first direction X on the hanger 1, so as to make it easier to calculate and adjust the positions of the hanging bracket assembly 2, the adjusting assembly 3, and the counterweight assembly 5 according to the center of gravity position of the component to be lifted, thereby improving the adjustment efficiency.

[0069] Optionally, the scale marking 13 includes multiple marking sections, each of which is configured to correspond one-to-one with the first connection hole 111 of the hanger 1, in order to simplify the calculation steps and improve the adjustment efficiency.

[0070] Optionally, among the multiple marking sections, the marking section indicating the zero point scale is located at the middle position of the hanger 1 along the first direction X, and the multiple marking sections of the scale marking 13 are symmetrically distributed with the marking section indicating the zero point scale as the center, that is, the marking sections on both sides of the zero point scale are opposite numbers and symmetrically distributed, so as to facilitate the balancing of the hanger 1.

[0071] Please see Figures 1 to 5 In some alternative embodiments, the lifting bracket assembly 2 includes a lifting member 23, which is disposed along a second direction Z on the side of the lifting bracket assembly 2 away from the lifting assembly 4 and is used to connect the component to be lifted. The length of the lifting member 23 of at least one lifting bracket assembly 2 along the second direction Z is adjustable, and the second direction Z intersects the first direction X.

[0072] By making the length of the lifting member 23 of at least one lifting bracket assembly 2 adjustable along the second direction Z, the length of the lifting member 23 can be adjusted according to the position of each lifting point on the component to be lifted along the second direction Z, so as to realize the universality of each component to be lifted and the lifting tool 10 under different lifting conditions, reduce the amount of lifting tool 10 materials, and improve lifting efficiency.

[0073] Optionally, the same lifting bracket assembly 2 may include multiple lifting connectors 23 to connect with the lifting points of the component to be lifted through the multiple lifting connectors 23, so as to reduce the number of lifting bracket assemblies 2 and realize the lightweight design of the lifting device 10.

[0074] In order to make the length of the lifting member 23 adjustable along the second direction Z, as an optional embodiment, the lifting member 23 includes a transition part 231, a third connector 232 and a third sling 233. The transition part 231 has a plurality of second connection holes 234 along the second direction Z, and the third sling 233 is connected to the second connection holes 234 through the third connector 232.

[0075] By providing multiple second connecting holes 234 along the second direction Z in the adapter 231, the length of the third sling 233 can be adjusted by passing the third connector 232 through one of the second connecting holes 234 in the adapter 231, so as to adapt to the lifting point positions on different components to be lifted, thereby improving the versatility of the lifting device 10.

[0076] Optionally, the third connector 232 can be configured as a pin, and the third sling 233 can be configured as a ring structure. The third sling 233 is sleeved on the third connector 232 to improve the load-bearing capacity of the third sling 233.

[0077] Optionally, the third sling 233 includes a shackle to achieve a reliable connection with the component to be lifted.

[0078] In summary, the lifting device 10 in this embodiment can be applied to the smooth lifting of various components to be lifted and under various lifting conditions, realizing the versatility and lightweight design of the lifting device 10, reducing costs, improving lifting efficiency, and making it easy to promote and apply.
