Abstract

The invention discloses a grounding knife-switch operating mechanism, which comprises a butt joint bracket; a telescopic pressing plate assembly rotatably installed on the butt joint support through a bearing, wherein a telescopic pressing plate used for pressing a cabinet grounding knife interlocking pressing plate downwards is installed on the telescopic pressing plate assembly; an operation head assembly in butt joint with a robot transmission mechanism, wherein the robot related transmission mechanism provides stretching and rotation freedom degrees; a butt joint groove matched with the grounding knife-switch operating rod is formed in the front end of the grounding knife-switch operating rod and is used for grounding knife-switch operation; the operation head assembly and the butt joint support are connected in a matched mode through a self-adaption assembly, and self-adaption positioning of the operation head assembly is achieved through the self-adaption assembly. According to the operation mechanism, five-degree-of-freedom passive self-adaption is achieved through the single-stage or double-stage internal and external hexagonal gap butt joint characteristic, large-torque transmission is achieved directly through the hexagonal connecting rods, the self-adaption capacity is high, and the structure is simple.

Description

technical field [0001] The invention relates to the field of mechanical structures, in particular to a grounding knife switch operating mechanism. Background technique [0002] Switching operation is an operation that changes the operating state of power grid equipment, and is an indispensable part of the power system. The operation of the grounding switch is a key step in switching the cabinet between standby and maintenance states. The operation of the 10kv switch cabinet grounding knife switch has difficulties such as small operating space, large operating torque, and the cabinet mechanism jamming robot is difficult to judge that the operation is in place. At the same time, there is a cabinet ground knife interlock plate pressure outside the ground knife switch operation hole of the switch cabinet. During the manual operation, both hands need to cooperate to complete the pressure plate depression and the insertion of the manual operating rod. [0003] The present invent...
