The embodiment of the invention provides a hydraulic system of a deicing vehicle and the deicing vehicle, the hydraulic system comprises a first oil pump, a first proportional multi-way valve, a first load module, a first main oil way, a plurality of branch oil ways and an oil return way, the first proportional multi-way valve comprises a plurality of electrically controlled proportional valve plates; the first load module comprises a plurality of load motors and is used for providing power for the corresponding deicing execution elements; the first main oil way is communicated with the first oil pump and the first proportional multi-way valve, so that the first oil pump can convey hydraulic oil to each proportional valve plate of the first proportional multi-way valve at the same time; the plurality of branch oil ways are communicated with the first proportional multi-way valve and the first load module so as to convey hydraulic oil to each load motor of the first load module; and each load motor of the first load module is communicated with the oil return path. According to the hydraulic system in the embodiment of the invention, the size of the opening of the proportional valve plate can be adjusted in an electric control mode so as to adapt to different load power requirements, power loss is reduced, and heat generated in work is reduced.

    本发明实施例提供一种除冰车的液压系统及除冰车,其中,液压系统包括第一油泵、第一比例多路阀、第一负载模组、第一主油路、多个支油路和回油路,第一比例多路阀包括多个电控的比例阀片;第一负载模组包括多个负载马达,用于为对应的除冰执行元件提供动力;第一主油路连通第一油泵和第一比例多路阀,以使第一油泵能够同时向第一比例多路阀的每个比例阀片输送液压油;多个支油路连通第一比例多路阀和第一负载模组,以向第一负载模组的每个负载马达输送液压油;第一负载模组的每个负载马达均与回油路连通。本发明实施例中的液压系统能够以电控的方式调节比例阀片的开口大小以适应不同的负载功率需求,减少了功率损失,降低了工作中所产生的热量。
