Description

Technical Field

[0001] This application relates to the field of wind power construction technology, specifically to a hoisting structure. Background Technology

[0002] During the construction of a wind power plant, the nacelle of the wind turbine generator needs to be installed on top of the tower. Therefore, a crane is required to lift the nacelle.

[0003] In related technologies, lifting points are provided at both ends of the top of the nacelle along its length. When hoisting the nacelle, the first ends of the two lifting devices are first connected to the lifting points at both ends of the top of the nacelle, then the second ends of the two lifting devices are connected to the hooks of the crane, and finally the crane is controlled to lift the hooks to raise the nacelle to the top of the tower.

[0004] However, since there are many models of nacelles, and the size, lifting point position and center of gravity of different models of nacelles are different, there will be a phenomenon of nacelle tilting when hoisting different models of nacelles, which makes it difficult to connect the nacelle to the tower and thus reduces the installation efficiency of wind turbine generators.

[0009] As an optional implementation, the lifting device assembly includes a connection position adjusting member, a sling adjusting member, and a sling connected in sequence. The end of the connection position adjusting member opposite to the sling adjusting member is connected to the lifting beam assembly, and the end of the sling opposite to the sling adjusting member is used to connect to the lifting device.

[0010] The connecting adjustment component has at least two connection points along its length; at least two of the connection points are switchably connected to the sling adjustment component.

[0013] As an optional implementation, the connecting position adjusting member is rotatably connected to the lifting beam assembly, and the sling adjusting member is rotatably connected to the sling.

[0014] As an optional implementation, the lifting beam assembly includes a main lifting beam and two secondary lifting beams, both of which are connected to the bottom of the main lifting beam;

[0015] Both of the secondary lifting beams are provided with the object to be lifted connection position; the object to be lifted connection position of one secondary lifting beam is used to connect the first lifting position of the object to be lifted, and the object to be lifted connection position of the other secondary lifting beam is used to connect the second lifting position of the object to be lifted;

[0016] The first ends of both of the lifting assemblies are connected to the main lifting beam.

[0017] As an optional implementation, the two secondary lifting beams are identical, and the axes of the two secondary lifting beams are parallel and perpendicular to the axis of the main lifting beam.

[0018] As an optional implementation, the main lifting beam is provided with multiple main beam connection positions at intervals along its own axial direction, and the end of the connection position adjustment component of the lifting device assembly that is away from the sling adjustment component of the lifting device assembly can be switched to connect with a single main beam connection position.

[0019] As an optional implementation, the secondary lifting beam can be switched to connect with a single connection point of the main beam;

[0022] Compared with the prior art, the beneficial effects of this application are at least as follows:

[0023] The lifting structure comprises a lifting beam assembly and two lifting tool assemblies.

This allows for adjustment of the angle of the object during lifting, preventing tilting. In other words, using this lifting structure facilitates smooth lifting operations and improves lifting efficiency.

[0025] Furthermore, since the aforementioned hoisting structure is a purely mechanical structure, its reliability is high, thereby improving the safety of the hoisting structure. Also, the purely mechanical structure is simpler to maintain, thus reducing the daily maintenance costs of the hoisting structure. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] A crane is required to install the nacelle of a wind turbine generator on top of the tower. Lifting points are located at both ends of the nacelle's top. To lift the nacelle, the first ends of two lifting devices are connected to the lifting points at both ends of the nacelle's top. Then, the second ends of both devices are connected to the crane's hook. Finally, the crane is controlled to raise the hook, lifting the nacelle to the top of the tower.

[0035] However, due to the large variety of nacelle models, each with different dimensions, lifting point locations, and center of gravity positions, the nacelles may tilt during hoisting to ensure balanced torque around the hook. This tilting can hinder the docking of the nacelle with the tower, thus reducing the installation efficiency of the wind turbine.

[0036] To address the aforementioned technical problems, the hoisting structure provided by this utility model solves these problems by setting up a lifting beam assembly and two adjustable-length lifting tool assemblies. Specifically, the hoisting structure includes a lifting beam assembly and two lifting tool assemblies. The first end of one lifting tool assembly is connected to a first connection position of the lifting beam assembly, and the first end of the other lifting tool assembly is connected to a second connection position of the lifting beam assembly; the second ends of both lifting tool assemblies are used to connect to a lifting device, and the lengths of the lifting tool assemblies are adjustable. This allows adjustment of the relative height between the first and second connection positions of the lifting beam assembly during hoisting by adjusting the lengths of the two lifting tool assemblies, thereby enabling adjustment of the angle of the lifting beam assembly during hoisting.

[0037] The lifting beam assembly has at least two connection points for the object to be lifted. One connection point connects to the first lifting position of the object, and the other connects to the second lifting position. By adjusting the angle of the lifting beam assembly during lifting, the relative height of the two connection points can be adjusted, thereby adjusting the relative height of the first and second lifting positions. This allows for adjustment of the angle of the object during lifting, preventing tilting. In other words, using this lifting structure facilitates smooth lifting operations and improves lifting efficiency.

[0038] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0039] The following provides a detailed description of the specific structure of the aforementioned hoisting structure and various possible implementation methods.

[0040] Figure 1 This is a schematic diagram of a hoisting structure 100 provided in an embodiment of this application. Figure 2 This is a schematic diagram of a hoisting structure 100 provided in an embodiment of this application when hoisting an object 200 to be hoisted.

[0041] See Figure 1 and Figure 2The lifting structure 100 includes a lifting beam assembly 110 and two lifting device assemblies 120. The lifting beam assembly 110 has at least two connection positions 1121 for the object to be lifted. One connection position 1121 is used to connect to a first lifting position 210 of the object to be lifted 200, and the other connection position 1121 is used to connect to a second lifting position 220 of the object to be lifted 200. The first end of one lifting device assembly 120 is connected to the first connection position 1111 of the lifting beam assembly 110, and the first end of the other lifting device assembly 120 is connected to the second connection position 1112 of the lifting beam assembly 110. The second ends of both lifting device assemblies 120 are used to connect to a lifting device 300, and the length of the lifting device assembly 120 is adjustable.

[0042] In this embodiment, the hoisting structure 100 includes a lifting beam assembly 110 and two lifting device assemblies 120. The first end of one lifting device assembly 120 is connected to the first connection position 1111 of the lifting beam assembly 110, and the first end of the other lifting device assembly 120 is connected to the second connection position 1112 of the lifting beam assembly 110. The second ends of both lifting device assemblies 120 are used to connect to the lifting device 300, and the length of each lifting device assembly 120 is adjustable. Thus, by adjusting the lengths of the two lifting device assemblies 120, the relative height between the first connection position 1111 and the second connection position 1112 of the lifting beam assembly 110 during hoisting can be adjusted, thereby allowing adjustment of the angle of the lifting beam assembly 110 during hoisting.

[0043] Because the lifting beam assembly 110 is provided with at least two lifting connection positions 1121, one of these positions is used to connect to the first lifting position 210 of the object 200, and the other is used to connect to the second lifting position 220. By adjusting the angle of the lifting beam assembly 110 during the lifting process, the relative height of the two lifting connection positions 1121 can be adjusted. This, in turn, allows adjustment of the relative height between the first and second lifting positions 210, thereby adjusting the angle of the object 200 during lifting to prevent tilting. In other words, using this lifting structure 100 to lift the object 200 facilitates smooth lifting operations and improves lifting efficiency.

[0044] Furthermore, since the aforementioned hoisting structure 100 is a purely mechanical structure, its reliability is high, thereby improving its safety. Also, the purely mechanical structure is simpler to maintain, thus reducing the daily maintenance costs of the hoisting structure 100.

[0045] It should be noted that the first hoisting position 210 and the second hoisting position 220 may be equipped with lifting rings or hooks, or other types of connecting devices. This application embodiment does not limit this.

[0046] It should also be noted that the lifting device 300 mentioned above can be a hook or rope, or other structures used for lifting, and this application embodiment does not limit this.

[0047] It should also be noted that the object to be lifted 200 may be the nacelle of a wind turbine generator set or other objects that need to be lifted. This application embodiment does not limit this.

[0048] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The lifting assembly 120 includes a connection position adjusting member 121, a sling adjusting member 122, and a sling 123 connected in sequence. One end of the connection position adjusting member 121, away from the sling adjusting member 122, is connected to the lifting beam assembly 110. The other end of the sling 123, away from the sling adjusting member 122, is used to connect to the lifting device 300. The connection position adjusting member 121 has at least two connection points 1211 along its length, and these at least two connection points 1211 are switchably connected to the sling adjusting member 122.

[0049] In this embodiment, the lifting device assembly 120 includes a connection position adjustment member 121, a sling adjustment member 122, and a sling 123 connected in sequence. One end of the connection position adjustment member 121 facing away from the sling adjustment member 122 is connected to the lifting beam assembly 110, and the other end of the sling 123 facing away from the sling adjustment member 122 is used to connect to the lifting device 300. Thus, when the lifting device 300 moves upward, it can drive the connection position adjustment member 121 to move upward, which in turn can drive the lifting beam assembly 110 to move upward, thereby lifting the object 200 to be lifted.

[0050] Since the connecting position adjustment member 121 has at least two connection points 1211 along its own length direction, and at least two connection points 1211 can be switched to the sling adjustment member 122, the total length of the lifting device assembly 120 is different when the sling adjustment member 122 is connected to different connection points 1211 on the connecting position adjustment member 121, thereby realizing the function of length adjustment of the lifting device assembly 120.

[0051] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The connecting position adjustment component 121 is provided with three connecting points 1211.

[0052] When the sling adjuster 122 is connected to three different connection points 1211, the total length of the lifting assembly 120 has three different length values. These three length values ​​can meet the length adjustment requirements of the lifting assembly 120 during lifting, and also make the structure of the connection point adjuster 121 relatively simple, thus facilitating later maintenance.

[0053] It should be noted that the number of the above-mentioned connection points 1211 can also be four, five or more, and this application embodiment does not limit this.

[0054] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The lifting device assembly 120 also includes a pin 124, a connection point 1211 which is a first connection hole, and a sling adjuster 122 which is provided with a second connection hole. At least two of the first connection holes can be switched to be connected to the second connection hole through the pin 124.

[0055] By passing the pin 124 through a first connecting hole and a second connecting hole, the connecting position adjusting member 121 and the sling adjusting member 122 can be connected. Furthermore, when the pin 124 is passed through different first connecting holes, the total length of the lifting assembly 120 is different, thus enabling the length adjustment function of the lifting assembly 120. In addition, the pin 124 allows for a detachable connection between the connecting position adjusting member 121 and the sling adjusting member 122, and also facilitates the later maintenance of the lifting assembly 120.

[0056] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The connecting position adjustment component 121 is rotatably connected to the lifting beam assembly 110, and the sling adjustment component 122 is rotatably connected to the sling 123.

[0057] This ensures that the axes of the connecting position adjustment component 121, the sling adjustment component 122, and the sling 123 are always aligned, meaning that the lifting assembly 120 is always in a straight line. This helps shorten the force transmission path, thus facilitating the transmission of the force applied by the lifting device 300 to the lifting beam assembly 110.

[0058] It should be noted that the above-mentioned rotating connection method can be bolt connection or connecting shaft connection, or other types of rotating connection method, and the embodiments of this application do not limit this.

[0059] It should be noted that the overall structure of the aforementioned connecting position adjusting member 121 and sling adjusting member 122 can also be replaced by a telescopic structure. This telescopic structure can be a hydraulic telescopic member, a mechanical telescopic member, or other types of telescopic structures; this application embodiment does not limit this.

[0060] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The lifting beam assembly 110 includes a main lifting beam 111 and two secondary lifting beams 112, both of which are connected to the bottom of the main lifting beam 111. Each of the two secondary lifting beams 112 is provided with a load-bearing connection position 1121. The load-bearing connection position 1121 of one secondary lifting beam 112 is used to connect to the first lifting position 210 of the object 200 to be lifted, and the load-bearing connection position 1121 of the other secondary lifting beam 112 is used to connect to the second lifting position 220 of the object 200 to be lifted. The first ends of both lifting assemblies 120 are connected to the main lifting beam 111.

[0061] In this embodiment, one secondary lifting beam 112 has a connecting position 1121 for connecting the object to be lifted 200 at its first lifting position 210, and the other secondary lifting beam 112 has a connecting position 1121 for connecting the object to be lifted 200 at its second lifting position 220. Thus, when using this lifting structure 100 to lift the object 200, the relative height of the two connecting positions 1121 can be adjusted by adjusting the height of the two secondary lifting beams 112 during the lifting process. This allows for adjustment of the relative height between the first lifting position 210 and the second lifting position 220 during the lifting process, thereby adjusting the angle of the object 200 during lifting to prevent it from tilting.

[0062] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The two secondary lifting beams 112 are identical, and their axes are parallel and perpendicular to the axis of the main lifting beam 111. In this way, when the weight of the object to be lifted 200 is transferred to the two secondary lifting beams 112, it helps the lifting structure 100 to be in overall force balance, thereby improving the safety of the lifting structure 100.

[0063] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4The main lifting beam 111 has multiple main beam connection positions 1113 spaced apart along its own axis. The end of the connection position adjustment component 121 of the lifting assembly 120 opposite to the sling adjustment component 122 of the lifting assembly 120 can be switched to connect with a single main beam connection position 1113.

[0064] When the length of the lifting assembly 120 is adjusted, a suitable main beam connection position 1113 can be selected based on the actual length of the lifting assembly 120, and the end of the connection position adjusting member 121 facing away from the sling adjusting member 122 can be connected to the selected main beam connection position 1113. This further ensures that the lifting structure 100 is in overall force balance, thereby further improving the safety of the lifting structure 100.

[0065] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The secondary lifting beam 112 can be switched to connect to a single main beam connection position 1113. One end of a connection position adjuster 121 facing away from the sling adjuster 122 and a secondary lifting beam 112 are both connected to a main beam connection position 1113, and the other end of a connection position adjuster 121 facing away from the sling adjuster 122 and another secondary lifting beam 112 are both connected to another main beam connection position 1113.

[0066] Because different objects 200 have different sizes, the distance between the first lifting position 210 and the second lifting position 220 will also be different. To accommodate this, in this embodiment, the secondary lifting beam 112 can be switched to connect with a single main beam connection position 1113. This allows the distance between the two secondary lifting beams 112 to be adjusted by changing the connection position of the secondary lifting beam 112 on the main beam. This enables the adaptation to different distances between the first lifting position 210 and the second lifting position 220, thereby expanding the applicability of the lifting structure 100.

[0067] Because one end of a connecting position adjuster 121 facing away from the sling adjuster 122 and a secondary lifting beam 112 are both connected to a main beam connecting position 1113, and the other end of a connecting position adjuster 121 facing away from the sling adjuster 122 and another secondary lifting beam 112 are both connected to another main beam connecting position 1113, the weight of the object 200 to be lifted can be directly transferred to the connecting position adjuster 121 through the secondary lifting beam 112, that is, the weight of the object 200 to be lifted can be directly transferred to the lifting device assembly 120 through the secondary lifting beam 112. This helps to shorten the weight transfer path, thereby making the lifting structure 100 more stable during use.

[0068] It should be noted that the aforementioned main beam connection position 1113 can be a main beam connection hole or a main beam connection protrusion, or it can be other types of main beam connection positions 1113. This application embodiment does not limit this.

[0069] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The secondary lifting beam 112 is provided with multiple lifting connection positions 1121 at intervals along its own axis. The multiple lifting connection positions 1121 of one secondary lifting beam 112 can be switched to the first lifting position 210 of the object to be lifted 200, and the multiple lifting connection positions 1121 of another secondary lifting beam 112 can be switched to the second lifting position 220 of the object to be lifted 200.

[0070] Since different objects 200 have different sizes and shapes, the distribution of the first lifting position 210 and the second lifting position 220 on the object 200 is not fixed. To facilitate the connection of the first lifting position 210 and the second lifting position 220 of the object 200 to the two secondary lifting beams 112, in this embodiment, the secondary lifting beams 112 are provided with multiple object connection positions 1121 spaced apart along their own axis. Thus, multiple object connection positions 1121 of one secondary lifting beam 112 can be switched to the first lifting position 210 of the object 200, and multiple object connection positions 1121 of another secondary lifting beam 112 can be switched to the second lifting position 220 of the object 200. This makes it more convenient to connect the first lifting position 210 and the second lifting position 220 to the two secondary lifting beams 112, thereby improving the lifting efficiency of the lifting structure 100.

[0071] It should be noted that the above-mentioned multiple lifting object connection positions 1121 can be lifting object connection holes or lifting object connection protrusions, or other types of lifting object connection positions 1121. This application embodiment does not limit this.
