作为本发明的一种优选技术方案，所述第一脚轮、第二脚轮均为重型脚轮。
与现有技术相比，本发明能达到的有益效果是：
1、合理的结构设计
飞机发动机风扇叶片清洗润滑设备分为叶片存储车和清洗润滑装置两个部分，作业人员通过存储车将拆卸后的发动机叶片运送至防爆车间，与清洗润滑设备对接后即可进行自动化清洗、检测和润滑作业流程。叶片存储车设有定位导轨，便于与清洗润滑装置对接，设有叶片存储转轮盘、填隙片和填隙块叶片拆卸件存放区域，存储车整体高度不高于1.5m，不会遮挡操作人员视线。清洗润滑装置设有超声波清洗区域、机械清洗区域、机器视觉检测区域以及工业机器人润滑区域，根据工卡标准优化作业流程，同存储车对接后通过坐标机器人抓取叶片至作业区域，完成自动化清洗、检测和润滑作业流程。
2、组合式清洗技术
针对飞机发动机风扇叶片待清洗三个工件，叶片的燕尾基座区域、填隙片和填隙块拆卸件，单一清洗方式无法达到理想的清洁效果，因而采用组合式清洗方式完成清洁任务。对填隙块和填隙片的拆卸件，采用超声波清洗方式进行清洁，超声波设备底部、左侧和右侧均安置有振子发生器，超声清洗功率可以控制。对叶片燕尾基座区域的 清洗采用机械的方式，设计有啮合燕尾基座区域的异形槽以及喷淋装置，通过旋转气缸带动异形槽往复运动，完成对发动机叶片燕尾基座区域的清洁作业。
3、机器视觉检测技术
传统的发动机叶片清洁效果检测，通过人工目测的方式完成，具有很大的不确定性。为了提高准确性，在清洗润滑设备中设计有视觉检测工位，结合光电测距传感器、机器视觉光源、工业相机、工控机，对清洁后的叶片燕尾基座区域进行拍照、存储，在通过机器视觉的算法对拍照后图像进行处理，通过机器判断清洁度是否满足工卡要求，存储的图像信息也为后续飞机飞行安全追溯，提供数据保障。
4、工业机器人润滑技术
工业机器人具有重复定位精度高、稳定性强的技术优势，在发动机风扇叶片的润滑作业中，对润滑后图层的厚度有严格的要求。根据维修工卡标准，润滑需要使用二硫化钼喷罐标准航材，润滑工位通过六自由度工业机器人、二硫化钼喷罐存放装置，工业机器人末端设计有机械臂加持机构，抓取二硫化钼喷罐完成润滑任务，具有润滑均匀度强、润滑效率高的技术优势。
