Auxiliary equipment for carrying relay protection debugging instrument

The invention discloses auxiliary equipment for carrying a relay protection debugging instrument. The auxiliary equipment comprises a trolley; a grip structure; the supporting frame is provided with a supporting structure; a pair of crawler structures; a pair of wheels; a braking portion; the spring pushes the braking part body to make contact with the rotating piece so as to brake rotation of the rotating piece. And the spring is compressed to a stop state under the action of external force, so that the braking part main body is separated from the rotating piece and the rotating piece is allowed to rotate. The trolley according to the invention allows safe and flexible transportation of substation equipment, such as relay protection commissioning instruments, from ladders of any size or shape, including but not limited to spiral, straight and substantially horizontal planes. 本发明公开了一种载运继电保护调试仪辅助设备，包括：手推车；握把结构；具有支撑结构的支撑架；一对履带结构；一对轮子；制动部分；其中，弹簧推动制动部分主体与旋转件接触以制动上述旋转件的旋转；该弹簧受外力作用压缩至停用状态以使上述制动部分主体与上述旋转件隔开而允许旋转件旋转。
