The invention provides a truck device of an indoor railway vacuum circuit breaker. The truck device is connected with a circuit breaker operating mechanism; a rotary shaft of the device is fixed at the bottom of a truck support; a main shaft is fixed on two side plates below a truck support of the circuit breaker through a bearing; a driving plate is fixed on the rotary shaft through an elastic pin; a fork support is connected with the main shaft through a pin shaft; the rotary shaft rotates and drives the driving plate to rotate; the driving plate drives the main shaft to rotate through the fork support; the main shaft rotates and drives the truck frame to move back and forth; two ends of the main shaft are provided with end plates; and crank arm is welded on the main shaft. The beneficial effect of the invention is as follows: the indoor railway vacuum circuit breaker has high operation reliability and long service life, is maintenance-free and has good safety performance; while 300N.m output torque is ensured, the input torque is only 100N.m, which is convenient for switching the indoor vacuum circuit breaker between a working position and a test position, and the device can be widely applied to electrified railway tractive power supply systems.
Description
technical field [0001] The invention relates to an indoor railway vacuum circuit breaker handcart device. Background technique [0002] The indoor railway vacuum circuit breaker is a necessary product for the normal operation of the electrified railway. It bears the load current used to connect or disconnect the circuit during normal operation; It is the main equipment to ensure the normal operation of the line. It is mainly divided into two types: outdoor type and indoor type. Indoor vacuum circuit breakers are mainly used in traction substations. The requirements for indoor vacuum circuit breakers are high operational reliability, strong breaking capacity, and high safety performance. [0003] At present, most of the handcart devices of indoor railway vacuum circuit breakers at home and abroad adopt two transmission modes, one is screw drive and the other is worm gear drive. For example, the ZN85 indoor handcart vacuum circuit breaker handcart produced by Schneider adop...
