The invention relates to the technical field of aircraft refueling trucks, in particular to an aircraft refueling truck which comprises a power system, an engine, a first power takeoff, a second power takeoff, a first switch and a second switch, the first power takeoff and the second power takeoff are both in driving connection with the engine, the first switch is in signal connection with the first power takeoff and controls whether the first power takeoff is engaged or not, and the second switch is in signal connection with the second power takeoff and controls whether the second power takeoff operates; an oil pump which is in driving connection with the first power takeoff and is used for driving to realize an oiling function; and a hydraulic pump which is in driving connection with the second power takeoff and is used for providing hydraulic power for the aircraft refueling truck; wherein the normally open contact of the first switch is connected in series with the normally closed contact of the second switch, and the normally closed contact of the first switch is connected in series with the normally open contact of the second switch. Therefore, the oil pump and the hydraulic pump can be interlocked to prevent the hydraulic pump from malfunction when the oil pump works, so that the working safety of the aircraft refueling vehicle can be improved.
本发明涉及飞机加油车技术领域,特别涉及一种飞机加油车,其包括:动力系统,包括发动机、第一取力器和第二取力器、第一开关和第二开关,第一取力器和第二取力器均与发动机驱动连接,第一开关与第一取力器信号连接,并控制第一取力器是否挂合,第二开关与第二取力器信号连接,并控制第二取力器是否挂合;油泵,与第一取力器驱动连接,并用于驱动实现加油功能;和液压泵,与第二取力器驱动连接,并用于为飞机加油车提供液压动力;其中,第一开关的常开触点与第二开关的常闭触点串联,且第一开关的常闭触点与第二开关的常开触点串联。这样,油泵和液压泵可以互锁,防止油泵工作时,液压泵误动作,因此,有利于提高飞机加油车的工作安全性。
