Taking an exciter of a Taishan nuclear power model 175-45 as an example, 20 hydraulic bolts/nuts and 23 expansion pins are used for connecting an exciter armature and a generator rotor pair wheel. The hydraulic bolt is used for combining the generator rotor and the exciter armature cylinder, and the 23 expansion pins are positioned differently from the traditional positioning pins and are used for overcoming the shearing force generated by rotation in operation. Therefore, in the installation process of the exciter armature, the alignment and the complete attachment of the end face of the armature and the wheel-to-wheel face of the generator rotor need to be ensured, and all bolt holes are completely aligned. The exciter armature dismounting and storing device has the following using principle:

(1) Armature removing step

When the armature is removed, the distance between the two roller mechanisms 4 on the moving vehicle 3 is firstly adjusted to the maximum by the handle 62 on the driving mechanism 6, and then the device is moved to the lower part of the armature along the first direction by the travelling wheel 11 on the bracket body 1 to be aligned with the center of the armature. After the centering, the handle 62 of the driving mechanism 6 is swung to gradually reduce the distance between the two roller mechanisms 4 of the mobile vehicle 3 until the rollers 43 of the roller mechanisms 4 contact the armature. If necessary, the box jack screws 23 on both sides of the outer box 2 can be adjusted so that the trolley 3 moves in the second direction in the outer box 2 to assist the contact between the roller 43 of the roller mechanism 4 and the armature, and ensure that the center of gravity of the armature falls on the device. When the positions of the device and the armature are aligned, the handle and the bolt between the armature and the generator rotor are removed, and the end face of the armature is separated from the counter-wheel face of the generator rotor. The armature is fixed on the device by the anchor ear 12, the anchor ear connecting bolt is screwed, and then the support body 1 is hoisted by a crane to a maintenance area.

(2) Mounting work of armature

The armature is fixed on the device through the hoop 12, and the device containing the armature is lifted to the end face of the power generation rotor through the travelling crane. The armature is close to one side of the generator rotor along the first direction through the traveling wheels 11 at the bottom of the bracket body 1, the relative positions of the armature and the generator rotor are adjusted along the second direction through the box body jackscrews 23 on the outer box body 2, and the rolling contact height of the roller 43 and the armature, namely the relative height between the armature and the generator rotor, is adjusted through the handle 62 on the driving mechanism 6. After the position of the armature on the device is adjusted through the travelling wheels 11, the box body jackscrews 23 and the driving mechanism 6, the end face of the armature can be completely attached to the wheel-to-wheel face of the generator rotor, and the center height of the armature is aligned. When the armature and the generator rotor are aligned, the anchor ear connecting bolt is loosened to enable the armature to freely rotate on the roller 43, and the armature is rotated to enable the connecting holes to be aligned with the connecting holes at the two ends of the generator rotor. And after the connecting holes are aligned, the connecting bolts and the back expansion pins are installed to complete the armature installation.

(3) Storing and flipping armatures

The armature is fixed on the device through the hoop 12, and the setting of the hoop 12 can also restrict the armature upset simultaneously, and the device of setting can play the memory function to the armature. In the process of storing the armature, the movement of the bracket body 1 along the first direction can be limited through the arranged base jackscrew 14, the box jackscrew 23 on the outer box body 2 is abutted against the movable trolley 3 to limit the movable trolley 3 to move along the second direction, and when the driving mechanism 6 is not operated, the distance between the two roller mechanisms 4 is determined, and the height of the corresponding armature cannot be changed. The device of this application can play the function of stable storage to the armature promptly, even when overhauing the armature on the device, the device also can provide a firm holding power for the armature. When the armature on the device needs to be repaired and maintained, the whole circle of the armature needs to be inspected. If the existing tool is adopted, the armature needs to be lifted by means of the crane due to the fact that the existing tool does not have the overturning function, then the armature is overturned to a required angle, the crane is required to be lifted once every time the detection position is changed, and therefore the overhauling work of the armature becomes complex. In addition, in the process of lifting the travelling crane, the speed and the stability are not well controlled, and the fixed position of the armature needs to be adjusted, so that the maintenance of the armature is time-consuming and labor-consuming.
