For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of drive mechanism earthed switch, comprise the isolating switch mounting bracket, be installed with guide rail and isolating switch pedestal on the isolating switch mounting bracket, drive link and isolating switch pedestal flexibly connect, be with the earthed switch movable contact rod on the drive link, the clips that is fixed on the earthed switch movable contact rod is pulled by connection, support with the isolating switch pedestal and flexibly connect, clips flexibly connects between pulling with being connected, connection flexibly connects between pulling and supporting, the roller that is installed in earthed switch movable contact rod outside matches with guide rail, and the earthed switch fixed contact is fixed on the contact base of isolating switch.
Be equipped with a plurality of drive link rollers that match with the earthed switch movable contact rod on the drive link.
The quantity of drive link roller is two.
Support and drive link flexibly connect by pivot pin and isolating switch pedestal.
The isolating switch mounting bracket is the support that channel-section steel is made.
The drive mechanism earthed switch that the utility model provides, beneficial effect is as follows:
1, the step that rotatablely moves merely of existing earthed switch is closed a floodgate puts that becoming closes a floodgate in two steps puts in place in place, earthed switch movable contact rod rotatablely moving and the middle not pause of rectilinear motion in separating brake and making process, the reliable insertion of having guaranteed moving contact with contact reliably, can solve the problem that existing earthed switch capacity can not be satisfied the demand, improve the dynamic current that bears of earthed switch and the ability of heat-stable current, guaranteed contact reliability and the integral installation quality of earthed switch.
2, simple in structure, can operate practical, safe and reliable.
3, be designed to earthed switch movable contact rod moving linearly time guiding and positioning action, the accurate direction when guaranteeing earthed switch movable contact rod moving linearly of drive link roller.
