The embodiment of the invention discloses a travelling crane charging system and a travelling crane, the travelling crane charging system comprises a power distribution module and a charging port gating module, and the charging port gating module comprises a single selection linkage switch; a first fixed end of the single selection linked switch is electrically connected with a first input end of the power distribution module, and a second fixed end of the single selection linked switch is electrically connected with a second input end of the power distribution module; a third fixed end of the single selection linked switch is electrically connected with the alternating current charging port, and a fourth fixed end of the single selection linked switch is electrically connected with the direct current charging port; the first movable end and the second movable end of the single-selection linked switch are electrically connected, and the first movable end and the second movable end are fixedly connected. According to the system of the invention, different charging ports and charging piles are gated by using the single-selection linked switch, so that the alternating-current charging port and the direct-current charging port are not connected at the same time, the charging reliability is improved, and meanwhile, the damage to the battery and electric appliances of the whole vehicle caused by the short circuit of the charging ports is avoided.

    本发明实施例公开了一种行车充电系统和行车,该行车充电系统包括配电模块以及充电口选通模块,充电口选通模块包括单项选择联动开关;单项选择联动开关的第一不动端与配电模块的第一输入端电性连接,单项选择联动开关的第二不动端与配电模块的第二输入端电性连接;单项选择联动开关的第三不动端与交流充电口电性连接,单项选择联动开关的第四不动端与直流充电口电性连接;单项选择联动开关的第一动端和第二动端电性连接,且第一动端和第二动端固定连接。本发明实施例利用单项选择联动开关选通不同的充电口与充电桩,实现了交流充电口与直流充电口不同时接通,提高了充电的可靠性,同时避免了充电口短路对电池和整车电器带来的损坏。
