The loading arm structure comprises an auxiliary frame, a lifting arm telescopic mechanism, a telescopic arm, a bucket, a first connecting rod and a second connecting rod, the tail end of the telescopic arm is hinged to a front cross beam of the auxiliary frame, the two ends of the first connecting rod are hinged to the telescopic arm and the lifting arm telescopic mechanism respectively, and the first connecting rod is hinged to the front end of the second connecting rod; the tail end of the second connecting rod is hinged to the auxiliary frame, the auxiliary frame, the telescopic arm, the first connecting rod and the second connecting rod form a four-connecting-rod mechanism, the front end of the lifting arm telescopic mechanism is hinged to the first connecting rod, the tail end of the lifting arm telescopic mechanism is hinged to the middle of the auxiliary frame, and the lifting arm telescopic mechanism drives the telescopic arm to rotate when stretching out and drawing back. The bucket is hinged to the front end of the telescopic arm and is driven by the bucket telescopic mechanism to turn over. The invention further discloses the self-loading and self-unloading vehicle with the loading arm structure for the self-unloading vehicle. Self-loading of the dumper can be achieved, the rotating angle of the telescopic arm is large, materials in front of the dumper are shoveled and filled into a compartment behind a cab, and the working efficiency of the dumper is high.
本发明公开了一种自卸车用装载臂结构,包括副车架、升臂伸缩机构、伸缩臂、铲斗、第一连杆和第二连杆,伸缩臂的末端与副车架的前部横梁铰接,第一连杆的两端分别与伸缩臂和升臂伸缩机构铰接,第一连杆与第二连杆前端铰接,第二连杆的末端与副车架的铰接,副车架、伸缩臂、第一连杆和第二连杆构成四连杆机构,升臂伸缩机构的前端与第一连杆铰接,升臂伸缩机构的末端与副车架的中部铰接,升臂伸缩机构伸缩时驱动伸缩臂转动,铲斗铰接于伸缩臂的前端并由铲斗伸缩机构驱动翻转。本发明还公开了具有自卸车用装载臂结构的自装卸车。本发明可实现自卸车的自装载,伸缩臂旋转角度大,实现铲取车辆前方的物料并填装到驾驶室后方的车厢中,车辆的工作效率高。
