The invention relates to the technical field of engineering machinery, and provides a fuel oil system and engineering machinery, the fuel oil system comprises a fuel oil tank, a platform and a crawling ladder, the fuel oil tank is provided with a fuel oil filling port and an exhaust hole, the exhaust hole is provided with a first one-way valve which is conducted from inside to outside, and a buoy is arranged in the fuel oil tank; the quick refueling assembly is used for being communicated with a fuel filling port and used for filling fuel into the fuel tank, when the liquid level in the fuel tank reaches the preset liquid level, the buoy blocks the first one-way valve, and the quick refueling assembly stops; the platform is arranged on the side of the fuel tank and used for bearing operators. The crawling ladder is rotationally connected with the platform, and the crawling ladder is used for switching between a first position and a second position; when the crawling ladder is located at the first position, the crawling ladder is folded above the platform; when the crawling ladder is located at the second position, the crawling ladder is unfolded below the platform. When the fuel tank needs to be refueled or overhauled, an operator can go up and stand on the platform through the crawling ladder, so that the safety risk can be reduced, and the safety of the operator is ensured.

    本发明涉及工程机械技术领域,提供一种燃油系统及工程机械,燃油系统包括燃油箱、平台和爬梯,燃油箱设有燃油加注口和排气孔,排气孔处设有由内向外导通的第一单向阀,燃油箱内设有浮漂,快速加油组件用于与燃油加注口连通并用于为燃油箱加注燃油,燃油箱内液位达到预设液位时,浮漂封堵第一单向阀,快速加油组件停机;平台设在燃油箱侧部,用于承载操作人员;爬梯与平台转动连接,爬梯用于在第一位置和第二位置之间切换;爬梯位于第一位置时,爬梯收合在平台的上方;爬梯位于第二位置时,爬梯展开在平台的下方。在需要对燃油箱进行加油或进行检修时,操作人员可以通过爬梯上到并站在平台上,可降低安全风险,保证操作人员安全。
