行车电路保护系统
摘要：
本实用新型公开了一种行车电路保护系统，包括行车行走装置、，以及通过供电线路为行车行走装置提供电源并进行控制的控制器，所述的行走装置上设置有检测发射单元，检测发射单元通过信号反馈线路连接接收单元，接收单元连接控制开关；所述的供电线路经过行走装置上的检测发射单元后连接行走装置；所述的控制开关与接收单元设置在控制器内。本实用新型结构简单，且操作方便，通过在行走装置上设置检测发射单元，对行走装置的电源、电流进行检测，当发现波动时，立刻通过信号反馈线路对控制器进行反馈，并及时通过控制开关切断电源，进行检修，避免了因为线路漏电、短路、断路而造成的人员触电等危险的发生。
摘要（英）：

The utility model discloses a traveling crane circuit protection system which comprises a traveling crane traveling gear and a controller which provides power supply for the traveling crane traveling gear through a power supply line and controls the traveling crane traveling gear. A detection transmitting unit is arranged on the traveling gear. The detection transmitting unit is connected with a receiving unit through a signal feedback line. The receiving unit is connected with a control switch. The power supply line is connected with the traveling gear through the detection transmitting unit on the traveling gear. The control switch and the receiving unit are arranged in the controller. The traveling crane circuit protection system is simple in structure and convenient in operation, carries out detection on the power supply and the current of the traveling gear through arranging the detection transmitting unit on the traveling gear, carries out feedback on the controller through the signal feedback line when finding a wave motion, timely cuts off the power supply through the control switch, carries out maintenance, and avoids the people electric shock and other dangers caused by line electric leakage, short circuit or circuit break.
