Abstract

The invention discloses an isolating switch transmission device for track traffic. A direct current motor is connected with a worm speed reducer; an output shaft of the worm speed reducer is connected with a dynamic contact knife of an isolating switch through an insulating transmission shaft; a drive bevel gear on a manually operated transmission shaft which can be telescopically arranged is engaged with or disengaged from a driven bevel gear on another input shaft of the worm speed reducer; a switch-on / off locking structure comprises a switch-on / off position locking plate and a switch-on / off position locking rod which are fixed on an output shaft, etc.; an electric mode and manual operation mode selecting module is composed of a mode selecting locking rod, a clutch, a push plate, etc.; an electric mode and manual operation mode electrical interlocking mechanism is composed of a push plate, an electric position switch, a manual position switch, a mode knob, etc.; and a locking mode electric interlocking mechanism is composed of a mode knob and a locking position switch. The isolating switch transmission device for track traffic disclosed by the invention integrates locking, manual and electric operation modes into one, and each mode can be executed independently without interference to other modes, therefore, the isolating switch transmission device for track traffic is ingenious and practical in structural design, and has impeccable mechanical and electric interlocking performances.

Description

Technical field [0001] The present invention relates to an electrical isolating switch transmission device, in particular to an isolating switch operating device for rated voltage AC220V, DC220V, DC110V and rated current A, with mechanical and electrical interlocking protection. Background technique [0002] The Chinese patent document discloses a "operating mechanism for isolating switch of railway power line" (ZL94111497.X). It is a driving device used for automatic opening and closing of isolation switches in railway power transmission lines. It is mainly composed of sliding plate, cam drive mechanism, crankshaft, worm gear reducer, tension spring, electromagnet and so on. The device utilizes the sudden release of energy from the tension spring to rapidly drive the rotating shaft to achieve the purpose of quickly opening and closing the isolation switch. The device has manual operation mode and lock mode, and lacks mechanical and electrical self-locking functions. Summary o...
