Detailed description of the invention
The present invention is described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
The structure such as Fig. 1 of a kind of electric isolating switch being applied to rolling stock top that the present invention provides-
Shown in Fig. 3, including rotating insulated sub 1 and fixed insulation 2, the top of fixed insulation 2 connects to be had
Contact folder 4, the rotating insulated top of sub 1 connects moving conductive rod 3, the radius of turn of moving conductive rod 3
Not less than the centre-to-centre spacing between rotating insulated sub 1 and fixed insulation 2, rotating insulated sub 1 is fixed on
On final drive shaft 5, also include by bonded motor 9 and reductor 8, final drive shaft 5 and deceleration
The reductor shaft 7 of machine 8 is connected with each other by the most sheathed gear 6, final drive shaft 5 and reductor
Axle 7, by gear 6 driving torque, final drive shaft 5 is also arranged with cam 12, and cam 12 is stirred auxiliary
Contact 11, motor 9 is helped to be also associated with catalyst 10.
A kind of electric isolating switch being applied to rolling stock top of the present invention also includes mounting base 13,
Rotating insulated sub 1 and fixed insulation 2 can be secured by bolts on mounting base 13.
Contact folder is secured by bolts on fixed insulation.
Moving conductive rod is secured by bolts on rotating insulated son.
During work, catalyst 10 and auxiliary contact 11 are all connected with rolling stock managing and control system, when
Motor 9 obtains electric after being divided the instruction of (conjunction) lock simultaneously, and catalyst 10 is corresponding by adhesive (release)
Controlling motor 9 just (instead) to turn, just (instead) the turning of motor 9 converts electric energy to mechanical energy and (i.e. turns round
Square) drive reductor 8 to rotate, 8 moments of torsion of reductor are sent to after being amplified by internal structure slow down
On arbor 7, reductor shaft 7 drives final drive shaft 5 to rotate by gear 6, and final drive shaft 5 carries again
