[0044] As mentioned in the background technology, currently, when hoisting the wind power adapter ring, a steel wire rope is directly passed through the inner ring of the wind power adapter ring, or a steel wire rope is directly passed through the flange hole of the wind power adapter ring, and then the wind power adapter ring is hoisted and transported by a hoisting device. However, when hoisting the wind power adapter ring by the above method, the wind power adapter ring is easily damaged, which causes great damage to the wind power adapter ring.

[0045] Furthermore, it is not easy to find the balance point of lifting in the above method. After lifting, the wind turbine adapter ring is easy to deviate or even fall off the wire rope, posing a great safety hazard.

[0046] In view of the above-mentioned problems existing in the prior art, the utility model provides a wind power adapter ring lifting tool and a lifting device. The wind power adapter ring lifting tool includes a base, an ear plate and a traction assembly; the base is connected to the ear plate, and the base is used to fix the wind power adapter ring; a first through hole is provided on the ear plate, and the traction assembly is inserted on the ear plate through the first through hole, the traction assembly can rotate around the first through hole, and the traction assembly is used to connect the wire rope. The wind power adapter ring lifting tool can cooperate with the wire rope, lifting equipment, etc. to lift the wind power adapter ring. Compared with directly lifting the wind power adapter ring by wire rope, the present application can reduce the damage to the wind power adapter ring; and, during the lifting process, the traction assembly will rotate around the first through hole according to the force direction to adjust the angle to ensure the stability of the lifting.

[0047] The following is an introduction to exemplary application scenarios of the present invention.

[0048] The wind power adapter ring lifting tool and lifting device provided by the utility model can be used to lift the wind power adapter ring. Specifically, the wind power adapter ring lifting tool provided by the utility model can reduce the damage to the wind power adapter ring when in use; and during the lifting process, the traction component will rotate around the first through hole according to the force direction to adjust the angle to ensure the stability of the lifting.

[0049] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0050] First, refer to Figure 1 As shown, the wind power adapter ring lifting tool 100 provided in the present application includes a base 110 , an ear plate 120 and a traction assembly 130 .

[0051] The base 110 is connected to the ear plate 120 , and the base 110 is used to be fixed to the wind power adapter ring 10 .

[0052] The ear plate 120 is provided with a first through hole 121 , and the traction assembly 130 is inserted into the ear plate 120 through the first through hole 121 . The traction assembly 130 can rotate around the first through hole 121 , and the traction assembly 130 is used to connect the steel wire rope 200 .

[0053] In the above scheme, the wind power adapter ring lifting tool 100 provided in the present application can be used to lift the wind power adapter ring 10 by cooperating with the wire rope 200, lifting equipment, etc. In the actual lifting process, two wind power adapter ring lifting tools 100 can be used to ensure the stability of the lifting process. The following takes the lifting of the wind power adapter ring 10 by two wind power adapter ring lifting tools 100 as an example for exemplary description.

[0054] Reference Figure 1 and Figure 4 As shown, the two bases 110 are respectively fixedly connected to the wind power adapter ring 10, and the two traction assemblies 130 are respectively connected to the lifting equipment through two steel wire ropes 200. Under the action of the lifting equipment, each steel wire rope 200 pulls the corresponding traction assembly 130 respectively, and lifts the wind power adapter ring 10 through the ear plate 120 and the base 110. When the steel wire rope 200 is twisted or the angle is not appropriate during lifting, the traction assembly 130 will rotate around the first through hole 121 according to the force direction to adjust the angle to ensure the stability of the lifting.

[0055] The wind power adapter ring lifting tool 100 provided in the present application can cooperate with the wire rope 200, lifting equipment, etc. to lift the wind power adapter ring 10. Compared with directly lifting the wind power adapter ring 10 through the wire rope 200, the present application can reduce the damage to the wind power adapter ring 10; and, during the lifting process, the traction assembly 130 will rotate around the first through hole 121 according to the force direction to adjust the angle to ensure the stability of the lifting.

[0056] The base 110 is mainly used to fix with the wind power adapter ring 10 to ensure the stability of the lifting process. For example, the base 110 can clamp the flange body of the wind power adapter ring 10 by means of a clamping claw; of course, holes can also be drilled on the base 110, and bolts can be passed through the holes and threadedly connected to the flange holes of the wind power adapter ring 10 to fix the base 110 to the wind power adapter ring 10, which is not limited here.

[0057] For example, refer to Figure 1 As shown, in order to facilitate the understanding of the direction, the direction indicated by X in the figure is the lifting direction of the wind power adapter ring 10 (that is, the vertical direction), and the rotation axis of the traction assembly 130 rotating around the first through hole 121 coincides with the lifting direction, so that the traction assembly 130 can swing laterally, so that during the lifting process, the traction assembly 130 will adjust the angle according to the force conditions to ensure the stability of the lifting.

[0058] Of course, the rotation axis of the traction assembly 130 rotating around the first through hole 121 is perpendicular to the lifting direction, so that the traction assembly 130 can swing vertically, which can also achieve the above effect.

[0059] Preferably, the midpoint of the line connecting the positions of the two bases 110 coincides with the axis of the wind power adapter ring 10 to ensure the stability of the lifting process and prevent the wind power adapter ring 10 from tilting.

[0060] Reference Figure 4As shown, during the hoisting process, due to factors such as the size of the flange body of the wind power adapter ring 10 and the length of the wire rope 200, there is an angle between the length direction of the wire rope 200 and the surface of the flange body of the wind power adapter ring 10. In the prior art, the ear plate 120 is vertically arranged with the base 110. When the wire rope 200 pulls the ear plate 120, a bending force is generated between the ear plate 120 and the base 110, resulting in cracks at the connection between the two. In addition, the force point of the flange body of the wind power adapter ring 10 deviates from the vertical direction during hoisting, causing it to bear additional stress, and thus it is easily damaged during the hoisting process.

[0061] In one embodiment, referring to Figure 1 and Figure 2 As shown, there is an angle between the base 110 and the ear plate 120 .

[0062] In the above embodiment, there is an angle between the base 110 and the ear plate 120. When hoisting, the extension direction of the ear plate 120 coincides with the length direction of the wire rope 200, so as to avoid bending force between the ear plate 120 and the base 110 when the wire rope 200 pulls the ear plate 120. In this way, the ear plate 120 only needs to bear tensile stress, so as to avoid cracking at the connection between the ear plate 120 and the base 110. In addition, the hoisting force point of the flange body of the wind power adapter ring 10 can be biased to the vertical direction, so as to reduce the force on the flange body of the wind power adapter ring 10 and prevent damage to it.

[0063] In a specific embodiment, referring to Figure 1 and Figure 2 As shown, the included angle between the base 110 and the ear plate 120 is in the range of greater than or equal to 10 degrees and less than or equal to 30 degrees.

[0064] In the above embodiment, the angle between the base 110 and the ear plate 120 can be adjusted according to actual conditions to a value greater than or equal to 10 degrees and less than or equal to 30 degrees based on factors such as the size of the flange body of the wind power adapter ring 10 or the length of the wire rope 200.

[0065] For example, refer to Figure 2 As shown, the angle a between the base 110 and the ear plate 120 may be 20 degrees.

[0066] Preferably, refer to Figure 1 and Figure 2 As shown, the base 110 and the ear plate 120 are bent and formed as one piece, which can save welding costs, ensure the connection strength between the base 110 and the ear plate 120, and improve stability during lifting.

[0067] In one embodiment, referring to Figure 1 and Figure 3 As shown, the traction assembly 130 includes a traction member 131 and a connecting member 132 .

[0068] The traction member 131 is bent to be inserted into the ear plate 120 . Both ends of the traction member 131 are provided with mounting portions 133 . The two mounting portions 133 are respectively located at two opposite sides of the ear plate 120 and correspond to the first through holes 121 .

[0069] The connecting member 132 is configured to connect the pulling member 131 and the ear plate 120 through a mounting portion 133 , the first through hole 121 and another mounting portion 133 in sequence.

[0070] In the above embodiment, the traction member 131 has a bending section. When the traction assembly 130 is connected to the steel wire rope 200, the rope loop of the steel wire rope 200 can be hung at the bending section, and then the traction member 131 is inserted on the ear plate 120, and the traction member 131 and the ear plate 120 are connected through the connecting member 132 through a mounting portion 133, a first through hole 121 and another mounting portion 133 in sequence, so as to limit the rope loop of the steel wire rope 200 to the bending section. This structural setting can facilitate the installation of the steel wire rope 200 and the traction assembly 130.

[0071] During the lifting process, the rope loop of the wire rope 200 can slide in the bending section, and the connecting member 132 can also rotate in the first through hole 121, so that the traction member 131 can rotate around the first through hole 121, so that the traction member 131 can rotate and adjust the angle in time according to the force direction to ensure the stability of the lifting.

[0072] Preferably, refer to Figure 1 and Figure 3 As shown, the traction member 131 can be a U-shaped structural member, and the two mounting portions 133 are respectively located at the two ends of the U-shaped structural member, and the bending section is an arc section of the U-shaped structural member. This structural setting can make the rope loop of the wire rope 200 slide more smoothly in the bending section and allow the rope loop of the wire rope 200 to have a larger movement space.

[0073] Specifically, refer to Figures 1 to 3 As shown, there is an angle between the base 110 and the ear plate 120, and the first through hole 121 is located at the end of the ear plate 120 away from the base 110, so that the traction member 131 can be against the side of the ear plate 120 when no lifting work is performed, and it can also avoid the traction member 131 from colliding or rubbing with the wind power adapter ring 10, thereby preventing the wind power adapter ring 10 from being damaged.

[0074] In a specific embodiment, referring to Figure 3 As shown, a mounting hole is provided on the mounting portion 133, and the connecting member 132 is inserted into the mounting hole and threadedly connected to the mounting hole.

[0075] There is a gap between the connecting member 132 and the first through hole 121 .

[0076] In the above embodiment, the connecting member 132 is threadedly connected to the mounting hole, which can facilitate the installation between the connecting member 132 and the mounting portion 133 and ensure the stability of the connection between the connecting member 132 and the mounting portion 133. There is a gap between the connecting member 132 and the first through hole 121, so that the connecting member 132 can rotate in the first through hole 121 and reduce the friction force when the connecting member 132 rotates.

[0077] For example, refer to Figure 3 As shown, the mounting portion 133 may be a circular ring-shaped structural member, and a threaded hole is provided inside the circular ring-shaped structural member. The circular ring-shaped structural member may be integrally bent and formed with the U-shaped structural member to increase the connection strength.

[0078] In a specific embodiment, referring to Figure 1 As shown, one end of the connecting member 132 has a handle 134 .

[0079] In the above embodiment, the handle 134 can facilitate the installation between the connecting member 132 and the installation portion 133 .

[0080] Specifically, refer to Figure 1 As shown, by rotating the handle 134 on the connecting member 132 , the connecting member 132 can be quickly threadedly matched with the mounting hole on the mounting portion 133 .

[0081] In one embodiment, referring to Figure 1 and Figure 2 As shown, the wind power adapter ring lifting tool 100 provided in the present application also includes a fastener 140 , and the fastener 140 is used to fix the base 110 on the wind power adapter ring 10 .

[0082] In the above embodiment, the base 110 can be fixed to the flange body of the wind power adapter ring 10 by means of the fastener 140 .

[0083] In a specific embodiment, referring to Figure 1 and Figure 2 As shown, the fastener 140 is a bolt, and the base 110 is provided with a second through hole 111 .

[0084] The bolts are configured to be threadedly connected to the threaded holes on the wind power adapter ring 10 through the second through holes 111 , so as to fix the base 110 on the wind power adapter ring 10 .

[0085] In the above embodiment, the base 110 is threadedly connected to the threaded holes on the wind power adapter ring 10 by bolts to ensure that the base 110 is firmly fixed on the wind power adapter ring 10, thereby ensuring the stability of the lifting process.

[0086] In a specific embodiment, referring to Figure 1As shown, the number of the bolts is two, the number of the second through holes 111 is two, and the bolts and the second through holes 111 are arranged correspondingly.

[0087] In the above embodiment, the number of the bolts and the number of the second through holes 111 are both two, so as to increase the stability of the connection between the base 110 and the wind power adapter ring 10 .

[0088] In the second aspect, the present application also provides a wind power adapter ring lifting device, referring to Figure 4 As shown, it includes a driving assembly (not shown in the figure), at least two steel ropes 200 and at least two lifting tools as above.

[0089] Each lifting tool is fixed on the wind power adapter ring 10 .

[0090] One end of each steel wire rope 200 is connected to the driving assembly, and the other end of each steel wire rope 200 is respectively connected to the traction assembly 130 of each lifting tool.

[0091] In the above technical solution, since the wind power adapter ring lifting device adopts the wind power adapter ring lifting tool 100 in the above embodiment, it also correspondingly has the advantages and benefits brought by the above wind power adapter ring lifting tool 100, that is, it can reduce the damage to the wind power adapter ring 10; and, during the lifting process, the traction assembly 130 will rotate around the first through hole 121 according to the force direction to adjust the angle to ensure the stability of the lifting.

[0092] Exemplarily, the driving assembly is mainly used to provide power for lifting the wind power adapter ring 10. The driving assembly can be a lifting equipment such as a crane in the prior art, which will not be described in detail here.
