The invention discloses a loading and unloading trolley for a circuit breaker. The loading and unloading trolley comprises a base; a plurality of universal wheels with brakes are arranged on the lowerend surface of the base; a center supporting plate is arranged over the base in a lifting mode; limiting moving plates are arranged on the left side and the right side of the center supporting platein a left-right moving mode; the pair of limiting moving plates and the central supporting plate are arranged in a synchronous lifting manner; a plurality of limiting pins evenly distributed front andback are formed on the end faces, away from each other, of the pair of limiting moving plates; a plurality of limiting through holes which are uniformly distributed front and back and allow the limiting pins to penetrate through are formed in connecting plates; when the limiting moving plates abut against the connecting plate on the corresponding side, the limiting pins penetrate through the limiting through holes in the corresponding side, and the ends, away from the limiting moving plates, of the limiting pins exceed the connecting plate; left and right blocking plates are formed on the upper end faces of the limiting moving plates.

    本发明公开了一种断路器的装卸小车,包括底座;底座的下端面上设置有若干带刹车的万向轮;底座的正上方升降设置有中心支撑板;中心支撑板的左侧和右侧分别左右移动设置有限位移动板;一对限位移动板与中心支撑板同步升降设置;一对限位移动板相互远离的端面上分别成型有若干前后均匀分布的限位销;连接板上成型有若干前后均匀分布的供限位销穿过的限位穿孔;当限位移动板抵靠住相应侧的连接板时,限位销穿过相应侧的限位穿孔并且限位销远离限位移动板的一端超出连接板;限位移动板的上端面上成型有左右阻挡板。
