[0050] Reference Figure 1 to Figure 2As shown, a rotor pole bidirectionally adjustable lifting device provided in this embodiment includes a fixing frame; the fixing frame includes a first connecting rod 5, a first baffle 2 and a second baffle 7; the number of the first connecting rods 5 is two, and the two first connecting rods 5 are arranged at intervals.

[0051] The fixing frame is a frame-shaped structure.

[0052] The fixing frame is formed by plate-shaped or rod-shaped components. In the present embodiment, the fixing frame is formed by a first baffle plate 2, a second baffle plate 7 and two first connecting rods 5 which are arranged at intervals.

[0053] A plurality of first clamping parts and a plurality of second clamping parts are arranged at intervals along the length direction on the first connecting rod 5, and the plurality of first clamping parts and the plurality of second clamping parts are arranged at intervals along the length direction; third clamping parts cooperating with the first clamping parts are respectively arranged at both ends of the first baffle 2, and fourth clamping parts cooperating with the second clamping parts are respectively arranged at both ends of the second baffle 7, the third clamping parts at both ends of the first baffle 2 cooperate with different first clamping parts, and the fourth clamping parts at both ends of the second baffle 7 cooperate with different fourth clamping parts; the first baffle 2, the second baffle 7 and the first connecting rod 5 jointly enclose fixed cavities of different sizes, and the fixed cavities are used to be enclosed on the rotor pole 4 to fix the rotor pole 4.

[0054] The two first connecting rods 5 are respectively provided with a first clamping portion and a second clamping portion, and the number of the first clamping portion and the second clamping portion are both provided in plurality. Meanwhile, a third clamping portion is provided at both ends of the first baffle plate 2, and a fourth clamping portion is provided at both ends of the second baffle plate 7. The first baffle plate 2 is clamped with the first clamping portions corresponding to each other in the two first connecting rods 5 through the third clamping portions provided at both ends thereof, and the second baffle plate 7 is clamped with the second clamping portions corresponding to each other in the two first connecting rods 5 through the fourth clamping portions provided at both ends thereof. When the specification and size of the rotor pole 4 change, the size of the fixed cavity can be adjusted by adjusting the third clamping portion in the first baffle plate 2 to clamp with different first clamping portions, and adjusting the fourth clamping portion in the second baffle plate 7 to clamp with different second clamping portions.

[0055] A clamping assembly 1 is provided on the fixing frame; the clamping assembly 1 has a locked state and an unlocked state. In the locked state, the clamping assembly 1 is fixed on the rotor pole 4, and in the unlocked state, the clamping assembly 1 is separated from the rotor pole 4.

[0056] In order to ensure the fixing effect of the rotor pole 4, a clamping assembly 1 is also provided on the fixing frame. When the clamping assembly 1 is locked, the rotor pole 4 and the fixing frame can be locked together to ensure that the rotor pole 4 is prevented from slipping or tilting relative to the fixing frame during the subsequent movement process.

[0057] In the present application, the first baffle 2 and the second baffle 7 can be adjusted between the two first connecting rods 5 along the length direction of the first connecting rod 5, thereby forming fixed cavities of different sizes. In addition, since the first baffle 2 and the second baffle 7 can be adjusted, the adjustment range of the rotor pole 4 along the length direction of the first connecting rod 5 is wider, and the rotor pole 4 can be moved as a whole, thereby avoiding one end of the rotor pole 4 from extending too long and interfering with subsequent installation; in addition, the clamping assembly 1 further limits the rotor pole 4 so that it is fixedly connected to the fixing frame, thereby ensuring the stability of the rotor pole 4 during the lifting process, thereby avoiding sliding or tilting problems, so as to ensure the accuracy of the subsequent installation of the rotor pole 4.

[0058] In some further embodiments, the clamping assembly 1 is disposed on the first connecting rod 5 , and / or the clamping assembly 1 is disposed on the first baffle plate 2 ; and / or the clamping assembly 1 is disposed on the second baffle plate 7 .

[0059] The clamping assembly 1 can be arranged on the first connecting rod 5, the first baffle plate 2, or the second baffle plate 7, or on any two of them, or on all three.

[0060] Reference Figure 1 , Figure 4 and Figure 5 As shown, in some further embodiments, the clamping assembly 1 includes a U-shaped clamp 111 and a clamping bolt 112, the U-shaped clamp 111 is sleeved on at least one of the first connecting rod 5, the first baffle 2 and the second baffle 7, the two side walls of the U-shaped clamp 111 are respectively located on both sides of the rotor pole 4, and a threaded hole is opened on at least one side wall of the U-shaped clamp 111, and the clamping bolt 112 is passed through the threaded hole; when the clamping assembly 1 is in a locked state, the clamping bolt 112 is tightened and abuts against the rotor pole 4.

[0061] The U-shaped clamp 111 has a U-shaped structure, in which the two side walls refer to two sections with free ends respectively, and a threaded hole is opened on any one of the side walls, and the clamping bolt 112 is screwed into the threaded hole. When locking, the screwed-in end of the clamping bolt 112 abuts against one side of the rotor pole 4, and the side wall of the U-shaped clamp 111 where the clamping bolt 112 is not provided abuts against the other opposite side of the rotor pole 4, thereby fixing the rotor pole 4 on the fixing frame to further ensure the fixing effect on the rotor pole 4.

[0062] In some further embodiments, a rotating handle 113 is provided at one end of the clamping bolt 112 away from the U-shaped clamp 111 .

[0063] In order to facilitate the rotation of the clamping bolt 112, a rotating handle 113 is provided at the end of the clamping bolt 112 facing away from the U-shaped clamp 111. When the rotor pole 4 needs to be fixed, the operator can rotate the handle 113 to rotate the clamping bolt 112, thereby facilitating the fixation of the rotor pole 4 without the need for additional tools, which is very convenient.

[0064] In some further embodiments, the two ends of the first connecting rod 5 are respectively a first end and a second end, a plurality of first clamping portions are arranged at the first end of the first connecting rod 5, and a plurality of second clamping portions are arranged at the second end of the first connecting rod 5; the clamping assembly 1 is arranged on the first baffle 2, and the end face of the second end of the first connecting rod 5 is provided with an arc-shaped transition surface 11, and the two ends of the arc-shaped transition surface 11 along the arc length direction are respectively connected to the end face of the first connecting rod 5 and any side face of the first connecting rod 5 along the thickness direction, or the two ends of the arc-shaped transition surface 11 along the arc length direction are respectively connected to the two side faces of the first connecting rod 5 along the thickness direction.

[0065] Specifically, Figure 1 As shown, the first end is Figure 1 The end at the upper left corner and the second end is Figure 2 The middle is located at the lower right corner.

[0066] The clamping assembly 1 is specifically located on the first baffle plate 2 and is used to clamp and fix the rotor pole 4 on the fixing frame. During the actual clamping and fixing, when the clamping assembly 1 is locked, it will also simultaneously fix itself to the first baffle plate 2 to ensure the fixing effect of the rotor pole 4.

[0067] In other embodiments, the end of the fixed frame located at the first end is used for lifting. When lifting, the entire fixed frame and the end of the rotor pole 4 located at the first end are lifted. In order to facilitate the lifting process to be more stable and easier, the end face of the second end of the first connecting rod 5 is provided with an arc-shaped transition surface 11. The two ends of the arc-shaped transition surface 11 along the arc length direction are respectively connected to the end face of the first connecting rod 5 and any side surface of the first connecting rod 5 along the thickness direction. Any side surface here refers to the side of the fixed frame that contacts the ground.

[0068] In other embodiments, 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 5 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.

[0069] In some further embodiments, one of the first clamping portion and the third clamping portion is the first clamping groove 12, and the other is the first clamping protrusion; one of the second clamping portion and the fourth clamping portion is the second clamping groove 9, and the other is the second clamping protrusion.

[0070] The cooperation between the first clamping part and the third clamping part, and the cooperation between the second clamping part and the fourth clamping part are both achieved by the cooperation of grooves and protrusions. Specifically, one of the first clamping part and the third clamping part is the first clamping groove 12, and the other is the first clamping protrusion; one of the second clamping part and the fourth clamping part is the second clamping groove 9, and the other is the second clamping protrusion.

[0071] In some further embodiments, a second connecting rod 10 is further included. The second connecting rod 10 is connected between the second ends of the two first connecting rods 5 and is located outside the fixing cavity.

[0072] The second connecting rod 10 is located outside the fixing cavity, that is, located on the side of the second baffle plate 7 away from the first baffle plate 2, so as to increase the stability of the entire fixing frame.

[0073] Reference Figure 1 and Figure 6 As shown, in some further embodiments, a limiting ring 6 is sleeved on the first connecting rod 5 , and a locking portion is provided on the limiting ring 6 . The locking portion is a locking bolt 512 , and the locking bolt 512 passes through the side wall of the limiting ring 6 which is screwed thereon.

[0074] 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 6 is provided on the first connecting rod 5. A locking portion is provided on the limiting ring 6. The locking portion can be a locking bolt 512. The locking bolt 512 passes through the side wall of the limiting ring 6. 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 5, thereby fixing the limiting ring 6 at a certain position of the first connecting rod 5, so as to limit the fixing clamp in the length direction of the first connecting rod 5, such as Figure 1 As shown, two limiting rings 6 are provided for each fixing clamp, and the two limiting rings 6 are respectively located on both sides of the fixing clamp along the length direction of the first connecting rod 5, so as to prevent the rotor pole 4 from moving relative to the length direction of the first connecting rod 5.

[0075] In some further embodiments, the first clamping portion is a first clamping groove 12, the third clamping portion is a first clamping protrusion, the second clamping portion is a second clamping groove 9, and the fourth clamping portion is a second clamping protrusion.

[0076] Specifically, the first clamping portion may be the first clamping groove 12, the third clamping portion may be the first clamping protrusion, the second clamping portion may be the second clamping groove 9, and the fourth clamping portion may be the second clamping protrusion. In other embodiments, the first clamping portion may also be the first clamping protrusion, the second clamping portion may also be the first clamping groove 12, the third clamping portion may be the second clamping protrusion, and the fourth clamping portion may also be the second clamping groove 9.

[0077] The first snap-fitting groove 12 and the second snap-fitting groove 9 are both arranged on two opposite side walls of the two first connecting rods 5; a connecting groove 713 is provided on the two first connecting rods 5 on the side facing away from each other, and the length direction of the connecting groove 713 is consistent with the length direction of the first connecting rod 5, and the bottom of any first snap-fitting groove 12 or second snap-fitting groove 9 is connected to the connecting groove 713; a fastener for connecting to the first snap-fitting protrusion and the second snap-fitting protrusion is provided in the connecting groove 713.

[0078] In order to further ensure the connection strength between the first baffle 2, the second baffle 7 and the two first connecting rods 5, a connecting groove 713 is set on the first connecting rod 5, and any one of the first snap-in groove 12 and the second snap-in groove 9 are connected to the connecting groove 713. A fastener is provided in the connecting groove 713. When the first snap-in protrusions at both ends of the first baffle 2 are snapped with the first snap-in groove 12, and the second snap-in protrusions at both ends of the second baffle 7 are snapped with the second snap-in groove 9, the fastener will be connected with the first snap-in protrusion and the second snap-in protrusion to prevent the first snap-in protrusion from being detached from the first snap-in groove 12, and the second snap-in protrusion from being detached from the second snap-in groove 9.

[0079] The fastener can be directly set in the connecting groove 713, or after the first clamping protrusion cooperates with the first clamping groove 12, and the second clamping protrusion cooperates with the second clamping groove 9, the fastener passes through the connecting groove 713 to achieve connection with the first clamping protrusion and the second clamping protrusion.

[0080] Specifically, taking the first baffle 2 as an example, the fastener can be a bolt 714. When the first clamping protrusion set at the end of the first baffle 2 is clamped in the first clamping groove 12, the bolt 714 is screwed into the first clamping groove 12 from the connecting groove 713, and is threadedly engaged with the threaded hole reserved in the end face of the first clamping protrusion, and the head of the bolt 714 is just located outside the first connecting groove 713, thereby fixing the first baffle 2.

[0081] 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 2, that is, on the first clamping protrusion. After the first clamping protrusion and the first clamping groove 12 are clamped with each other, the end of the screw will pass through the connecting groove 713 and be located outside the connecting groove 713, thereby being threadedly connected with the nut, thereby further fixing the first baffle 2.

[0082] In some further embodiments, an elastic plate 711 is provided on a side wall of the first baffle plate 2 opposite to the second baffle plate 7 .

[0083] Specifically, Figure 3As shown, taking the second baffle plate 7 as an example, 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 second baffle plate 7 cooperates with the two first connecting rods 5, a flexible pre-tightening force can be provided to the rotor pole 4. In addition, since the second baffle plate 7 is usually made of metal, the elastic plate 711 can also reduce the friction and scratching of the second baffle plate 7 on the rotor pole 4.

[0084] In some further embodiments, a lifting ring is provided on the first baffle 2 .

[0085] The first baffle plate 2 is provided with a lifting ring, which is used to lift the entire fixing frame and the rotor pole 4 . The lifting ring can be connected to the first baffle plate 2 by welding.
