[0043] Reference Figure 1 to Figure 2 As shown, a rotor pole lifting device provided in this embodiment includes a fixing frame; the fixing frame includes a first connecting rod 3, a second connecting rod 1 and a first baffle 7, the number of the first connecting rods 3 is two, the two first connecting rods 3 are arranged at intervals, and the second connecting rod 1 is connected between the two first connecting rods 3; a plurality of first clamping parts are arranged at intervals along the length direction on the first connecting rod 3, and the two ends of the first baffle 7 are respectively provided with second clamping parts that cooperate with the first clamping parts, and the second clamping parts at the two ends of the first baffle 7 cooperate with different first clamping parts, and the first baffle 7 and the first connecting rod 3 and the second connecting rod 1 jointly enclose fixed cavities of different sizes, and the fixed cavity is used to be enclosed on the rotor pole 4 to fix the rotor pole 4.

[0044] The fixing frame is formed by plate-shaped or rod-shaped components, and in this embodiment, is formed by the second connecting rod 1 , the first baffle 7 and the two first connecting rods 3 .

[0045] Usually, if Figure 1 As shown, the fixing frame is in a rectangular frame structure to fit the rotor pole 4 in a rectangular plate structure.

[0046] The second connecting rod 1 can be integrally arranged with the two first connecting rods 3 , for example, both ends of the second connecting rod 1 are directly welded to the first connecting rod 3 .

[0047] A first clamping portion is provided on each of the two first connecting rods 3, and the number of the first clamping portions is multiple, and the multiple first clamping portions are spaced apart along the length direction of the first connecting rod 3; correspondingly, second clamping portions are provided at both ends of the first baffle 7, and the second clamping portions can be clamped together with the first clamping portions. The second connecting rod 1, the two first connecting rods 3 and the first baffle 7 are jointly arranged to form a fixed cavity for fixing the rotor pole 4, and the size of the fixed cavity can be adjusted by the first baffle 7. Specifically, the second clamping portion at the end of the first baffle 7 can be clamped with different first clamping portions.

[0048] The rotor pole 4 hoisting device provided by the present application can set the second clamping portion on the first baffle 7 in different first clamping portions when facing rotor poles 4 of different specifications and sizes, so as to enclose a fixed cavity of adjustable size for enclosing the rotor pole 4, thereby achieving universality for rotor poles 4 of different specifications. In addition, the stability of the rotor pole 4 during the hoisting process can also be ensured by the fixing frame of the surrounding structure, thereby avoiding the problem of sliding or tilting, so as to ensure the accuracy of the subsequent installation of the rotor pole 4.

[0049] In some further embodiments, the first clamping portions on the two first connecting rods 3 are arranged in one-to-one correspondence.

[0050] In actual situations, the two ends of the two first connecting rods 3 are usually aligned, so the multiple first clamping parts arranged on the two first connecting rods 3 are relatively arranged, so that when the second clamping parts at both ends of the first baffle 7 are clamped in the first clamping parts, the first baffle 7 and the two first connecting rods 3 are perpendicular to each other.

[0051] In some further embodiments, one of the first clamping portion and the second clamping portion is a clamping groove 9, and the other is a clamping protrusion.

[0052] In this embodiment, the first baffle 7 is connected to the first connecting rod 3 by plugging, that is, in different embodiments, the first clamping portion can be a clamping groove 9, and the second clamping portion can be a clamping protrusion, while in other embodiments, the first clamping portion can also be a clamping protrusion, and the second clamping portion is the clamping groove 9. Both methods can realize the connection between the first baffle 7 and the first connecting rod 3.

[0053] In some further embodiments, a fixing strap is further included, which passes through the rotor pole 4 and the two first connecting rods 3 from one side of the rotor pole 4 and is then tied and fixed on the other side of the rotor pole 4 .

[0054] In order to further ensure the firmness of the fixation of the rotor pole 4, a fixing strap is also provided on the fixing frame, and the fixing strap is wound around the fixing frame and the rotor pole 4 at the same time. For example, the fixing strap is wound around one side of the rotor pole 4 from one of the first connecting rods 3, and then around another first connecting rod 3 and then around the other side of the rotor pole 4 and finally connected to the initial first connecting rod 3, so as to further fix the rotor pole 4 and prevent it from slipping relative to the fixing frame during the sliding process.

[0055] In some further embodiments, a fixing portion is provided on the first connecting rod 3, and the fixing strap cooperates with the fixing portion.

[0056] Specifically, a fixing portion is also provided on the first connecting rod 3, and the fixing portion is mainly used to prevent the fixing strap from sliding relative to the first connecting rod 3. The fixing portion can be a slot formed between two protrusions, a notch directly formed on the first connecting rod 3, or a hole provided on the first connecting rod 3, etc.

[0057] In some further embodiments, the fixing portion includes a fixing hole 6 , which penetrates the first connecting rod 3 along the thickness direction of the first connecting rod 3 , and the fixing strap is inserted into the fixing hole 6 .

[0058] Exemplarily, the fixing portion includes a fixing hole 6, which is passed through the first connecting rod 3 along the thickness direction of the first connecting rod 3. When the fixing strap is actually fixed, the fixing strap can be passed through the fixing holes 6 in the two first connecting rods 3, thereby bundling the rotor poles 4 and preventing the fixing strap from sliding relative to the first connecting rod 3.

[0059] In some further embodiments, the fixing portion is a fixing groove, and the fixing groove is arranged on the sides of the two first connecting rods 3 facing away from each other.

[0060] In addition, in some other embodiments, the fixing portion may also be a fixing groove. Specifically, the fixing groove is arranged on the side opposite to each other of the two first connecting rods 3, that is, the fixing groove is a slot structure, so that the strap can be clamped during the winding process, thereby achieving the limitation of the fixing strap in the length direction of the first connecting rod 3.

[0061] In some further embodiments, a limiting ring 5 is sleeved on the first connecting rod 3 , and a locking portion is provided on the limiting ring 5 ; the locking portion is a locking bolt 512 , and the locking bolt 512 passes through the side wall of the limiting ring 5 which is screwed thereon.

[0062] A fixing clamp is provided on some of the rotor poles 4 to fix the excitation winding. Therefore, in order to further fix the rotor pole 4, a limiting ring 5 is provided on the first connecting rod 3. A locking portion is provided on the limiting ring 5. The locking portion can be a locking bolt 512. The locking bolt 512 passes through the side wall of the limiting ring 5. When the locking bolt 512 is tightened, the screwed-in end of the locking bolt 512 abuts against the side wall of the first connecting rod 3, thereby fixing the limiting ring 5 at a certain position of the first connecting rod 3, so as to limit the fixing clamp in the length direction of the first connecting rod 3, such as Figure 1 As shown, two limiting rings 5 ​​are provided for each fixing clamp, and the two limiting rings 5 ​​are respectively located on both sides of the fixing clamp along the length direction of the first connecting rod 3, so as to prevent the rotor pole 4 from moving relative to the length direction of the first connecting rod 3.

[0063] In some further embodiments, the first clamping portion is a clamping groove 9 , and the clamping groove 9 is disposed on an opposite side wall of the two first connecting rods 3 .

[0064] Specifically, the first clamping portion may be a clamping groove 9 , which is provided on opposite side walls of the two first connecting rods 3 to facilitate the insertion of the end of the first baffle 7 .

[0065] A connecting groove 714 is provided on the side of the two first connecting rods 3 facing away from each other, and the length direction of the connecting groove 714 is consistent with the length direction of the first connecting rod 3; the bottom of any snap-in groove 9 is connected to the connecting groove 714; the second snap-in portion is a snap-in protrusion, and a fastener for connecting to the snap-in protrusion is provided in the connecting groove 714.

[0066] In order to further ensure the connection strength between the first baffle 7 and the two first connecting rods 3, a connecting groove 714 is set on the first connecting rod 3, and any one of the snap-in grooves 9 is connected to the connecting groove 714. A fastener is provided in the connecting groove 714. When the snap-in protrusions at both ends of the first baffle 7 are snap-fitted with the snap-in grooves 9, the fasteners will be connected with the snap-in protrusions to prevent the snap-in protrusions from being detached from the snap-in grooves 9.

[0067] The fastener may be directly disposed in the connecting groove 714 , or the fastener may be passed through the connecting groove 714 to achieve connection with the connecting protrusion after the connecting protrusion and the connecting groove 9 cooperate with each other.

[0068] Exemplarily, the fastener can be a bolt 713. When the snap-fitting protrusion set at the end of the first baffle 7 is snapped into the snap-fitting groove 9, the bolt 713 is screwed into the snap-fitting groove 9 from the connecting groove 714, and threadedly cooperates with the threaded hole reserved in the end face of the snap-fitting protrusion, and the head of the bolt 713 is located just outside the first connecting groove 714, thereby fixing the first baffle 7.

[0069] In addition, in other embodiments, the fastener may also be a nut, and a screw is arranged on the end face of the end of the first baffle 7, that is, on the snap-in protrusion. When the snap-in protrusion and the snap-in groove 9 are snap-fitted with each other, the end of the screw will pass through the connecting groove 714 and be located outside the connecting groove 714, thereby being screwed with the nut, thereby further fixing the first baffle 7.

[0070] In some further embodiments, an elastic plate 711 is provided on a side surface of the first baffle plate 7 opposite to the second connecting rod 1 .

[0071] Exemplarily, the elastic plate 711 can be a rubber plate or a silicone plate. The elastic plate 711 is used to provide a flexible pre-tightening force to the rotor pole 4, thereby ensuring that when the first baffle plate 7 is matched with the two second connecting rods 1, a flexible pre-tightening force can be provided to the rotor pole 4. In addition, since the first baffle plate 7 is usually metal, the elastic plate 711 can also reduce the friction and scraping of the first baffle plate 7 on the rotor pole 4.

[0072] In some further embodiments, a lifting ring is provided on the second connecting rod 1; an arc-shaped transition surface 11 is provided on the end of the two first connecting rods 3 away from the lifting ring, and the two ends of the arc-shaped transition surface 11 along the arc length direction are respectively connected to the end surface of the first connecting rod 3 and any side surface of the first connecting rod 3 along the thickness direction.

[0073] A lifting ring is provided on the second connecting rod 1. When lifting, the hook is connected to the lifting ring. As the lifting hook slowly rises, the entire fixed frame and the end of the rotor pole 4 provided with the second connecting rod 1 are lifted. In order to facilitate the lifting process to be more stable and easier, an arc-shaped transition surface 11 is provided at the end of the two first connecting rods 3 away from the second connecting rod 1. The arc-shaped transition surface 11 connects the end surface of the first connecting rod 3 away from the second connecting rod 1 and any side surface of the first connecting rod 3 along the thickness direction at both ends along its own arc length direction. Any side surface here refers to the side of the fixed frame in contact with the ground.

[0074] In some other embodiments, two ends of the arc-shaped transition surface 11 along the arc length direction are respectively connected to two side surfaces of the first connecting rod 3 along the thickness direction of the first connecting rod 3 .

[0075] Exemplarily, the two ends of the arc-shaped transition surface 11 along the arc length direction may also be directly connected to the two side surfaces of the first connecting rod 3 along its own thickness direction. Under this structure, when preparing the fixing frame, the placement process will be more convenient, and there is no need to pay special attention to which side the arc-shaped transition surface 11 is located.

[0076] It should be noted that the thickness direction of the first connecting rod 3 refers to the direction perpendicular to the plane where the fixing frame is located.

[0077] In other embodiments, two second connecting rods 1 are provided, and the two connecting rods are respectively located on both sides of the first baffle 7 .

[0078] In addition, in some other embodiments, a second baffle may also be provided inside the fixed cavity, and a plurality of third clamping portions may be provided on the second connecting rod 1 and the first baffle 7 that enclose the fixed cavity at intervals along their respective length directions, and correspondingly, fourth clamping portions are provided at both ends of the second baffle. Therefore, when facing rotor poles 4 with different widths, different rotor poles 4 can be adapted by adjusting the second baffle to clamp with different third clamping portions.

[0079] Exemplarily, the second baffle is a telescopic structure, and specifically may be a telescopic structure in the prior art that is nested with each other and can slide with each other.

[0080] The above is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments described herein, but will conform to the widest scope consistent with the principles and novel features applied for herein.
