[0030] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this utility model.

[0031] like Figure 1 、 8As shown in Figures 9 and 9, an embodiment of the present application shows a rotor disassembly and assembly tool suitable for a high-inertia distributed phase shifter. The rotor comprises a rotor body 10 and a non-outlet terminal 11 and an outlet terminal 12 located at opposite ends of the rotor body 10. During rotor installation, the rotor and stator need to be coaxially assembled. The stator mounting cavity is provided with a protective plate 13. After the rotor body 10 and the stator are assembled, the protective plate 13 is removed. The rotor disassembly and assembly tool is connected to a guide rail 6 fixed to a horizontal surface. A movable trolley 4 is rollingly connected to the guide rail 6. A body bracket 5 for supporting the rotor body 10 is provided above the movable trolley 4. The movable trolley 4 rolls along the extension direction of the guide rail 6, with one end of the guide rail 6 close to the stator base. During the installation of the rotor, the mobile trolley 4 drives the rotor body 10 to slide along the guide rail 6 and approach the stator base under the action of external force until the non-outlet end 11 is completely entered into the stator core body; the rotor disassembly and assembly tool also includes a first shaft neck bracket 2 and a second shaft neck bracket 3, which have the same structure and are used to support the rotor bearing block or oil block of the non-outlet end 11; it also includes a support plate 8 for supporting the rotor body 10 and an outlet end bracket 7 for supporting the rotor outlet end 12, and the outlet end bracket 7 is also arranged on the mobile trolley 4; an adjusting gasket is provided between the outlet end bracket 7 and the mobile trolley 4 for adjusting the vertical height of the outlet end bracket 7 to adjust the height of the supported outlet end 12 from the ground; the mobile trolley 4 slides on the guide rail 6 and drives the outlet end 12 to slide toward the stator installation cavity through it until the rotor body 10 and the stator are assembled.

[0032] Specifically, a fixed pulley 1 is fixed to the outlet end of the stator base, and a steel wire rope is used to pull the trolley 4 along the guide rail 6. The other end of the steel wire rope passes over the fixed pulley 1 and is fixed to the upper end of the stator base. A hand chain hoist or electric motor provides tension to the steel wire rope, which drives the trolley to move.

[0033] In this embodiment, in order to facilitate the disassembly of the rotor, a pier 9 is provided on the side of the guide rail 6 away from the stator base. When the rotor needs to be disassembled, the pier 9 is connected to the moving trolley 4 through a wire rope, providing pulling force to the moving trolley 4 to pull the moving trolley 4 along the guide rail 6.

[0034] The steps for installing the rotor are:

[0035] Step 1: If Figure 1 As shown, a protective plate 13 is installed in the stator mounting cavity, two fixed pulleys 1 are installed below the stator base wall near the outlet terminal 12, and the first and second journal brackets 2 and 3 are fastened to the inner and outer oil retaining blocks or bearing retaining blocks of the non-outlet terminal 11 of the rotor; wherein the bottom surfaces of the first and second journal brackets 2 and 3 are in the same plane;

[0036] Step 2: Install the moving trolley 4 and the rotor body bracket 5 at the center of gravity of the rotor body 10, ensuring that the center of gravity of the rotor body 10 falls smoothly on the rotor body bracket 5 installed on the moving trolley 4; the moving trolley 4 rolls on the guide rail 6; wherein the guide rail 6 is fixed to the anchor plate embedded in the foundation by bolts;

[0037] Step 3: The wire rope pulls the moving trolley 4 through the fixed pulley 1, so that the non-outlet end 11 of the rotor smoothly enters the stator installation cavity, as shown in the figure. Figure 2 As shown, when the moving trolley 4 approaches the stator base and the first journal bracket 2 is completely inserted into the core body, it stops; the first journal bracket 2 here is the first journal bracket to enter the stator mounting cavity; at the same time, a jack is used to support the outlet terminal 12 of the rotor until the weight of the rotor body 10 is supported by the first journal bracket 2 and the jack of the outlet terminal 12, and the rotor is supported by the jack and the body bracket 5 until the weight of the rotor is supported by the first journal bracket 2 and the body bracket 5; the moving trolley 4 is removed and moved to the other end of the guide rail 6;

[0038] Step 4: Remove the jack supporting the outlet terminal 12. At the same time, move the trolley 4 along the guide rail 6 to the outlet terminal 12, and cooperate with the outlet terminal bracket 7 to support the outlet terminal 12 of the rotor; use the jack to slowly lower the rotor so that the weight of the rotor is supported by the first journal bracket 2 and the outlet terminal bracket 7. Use the wire rope to pull the trolley 4 to ensure that the rotor continues to be steadily installed into the stator installation cavity;

[0039] Step 5: Figure 3 and Figure 4 As shown, after the second journal bracket 3 is successfully inserted into the core body, adjust the adjustment gasket between the movable carriage 4 and the non-outlet end bracket 7, and slowly lower the outlet end 12 of the rotor to ensure that the first journal bracket 2 is disengaged from the protective plate 13. The rotor is supported by the second journal bracket 3 and the outlet end bracket 7, and the rotor continues to be inserted;

[0040] Step 6: Figure 5 As shown, the rotor is pulled to the appropriate position in the stator mounting cavity. Before the second journal bracket 3 extends out of the stator inner bore, the jack supporting the rotor outlet 12 is used to support and lift the rotor. The support plate 8 is placed under the rotor body 10, and the rotor is slowly lowered using the jack. After ensuring that there is sufficient clearance between the second journal bracket 3 and the protective plate 13, the rotor is supported by the support plate 8 and the outlet bracket 7 and continues to be inserted.

[0041] Step 7: Figure 6 As shown, the rotor is inserted until it is aligned with the center line of the stator. After the rotor is in place, install the lower end covers and bearings at both ends, then remove the journal bracket, support plate, fixed pulley, outlet end bracket, trolley body and guide rail tool, and the rotor installation is completed.

[0042] To remove the rotor, follow the opposite steps. Figure 7 As shown, only the non-outlet end 11 is pulled by the support 9, which can also ensure the rotor is pulled out and the rotor is disassembled.

[0043] The rotor is supported by the first journal bracket 2, the second journal bracket 3, the support plate 8 and the movable trolley 4, and the fixed pulley 1 or the pier 9 provides traction to the movable trolley to realize the disassembly and assembly of the rotor, thereby solving the problem of completing the rotor disassembly and assembly work without moving the flywheel device at the non-outlet end of the phase regulator.

[0044] The rotor disassembly and assembly tool can complete the rotor disassembly and assembly of various equipment at the non-outlet end without moving them, and is not limited to high-inertia distributed phase regulators with flywheel devices installed at the non-outlet end.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
