Embodiment
As shown in figure 1, carbon brush holder support adjusting rod of the present invention includes the support bar 3 for screwing in footing 12, cylinder manifold 2 is fixed on
The top of support bar 3 is simultaneously insulated with support bar 3, one end of cylinder manifold 2 connection excitation external power supply cable 7, cylinder manifold 2 it is another
End connection carboloy holder 1, carboloy holder 1 is used to install carbon brush；Cylinder manifold 2 is respectively provided on two sides with up and down with the connecting portion of support bar 3
Pressure-bearing felt pad 6, the top of pressure-bearing felt pad 6 of upside is provided with clamp nut 5, and the pressure-bearing of upside is insulated by clamp nut 5
Pad 6 is pressed on cylinder manifold 2, and the top of clamp nut 5 is provided with the locking nut 4 for preventing that clamp nut 5 from loosening.Support bar 3
Bottom is provided with the locking nut 11 for being close to footing 12, and the top of locking nut 11 is provided with back nut 10, and back nut 10 is under
Provided with the high-strength insulating overcoat 9 being enclosed within support bar 3 between the pressure-bearing felt pad 6 of side, there is insulation in high-strength insulating overcoat 9
Packing material, high-strength insulating overcoat 9 is to bear the pressure applied of clamp nut 5；The contact with cylinder manifold 2 of support bar 3
Wrap up one layer of insulating barrier for meeting insulating requirements in position.
Insulation filling material 8 of the present invention first determines the position of back nut 10, from support bar when filling making
