The invention provides an aircraft maintenance ground trolley. The aircraft maintenance ground trolley comprises a truck chassis; the workbench is arranged above the shear fork lifting mechanism and is hinged to one end of the shear fork lifting mechanism, and the other end of the shear fork lifting mechanism is in sliding connection; the shear fork lifting mechanism is arranged on the truck chassis; the invention discloses a scissor lifting mechanism, which is characterized by comprising scissor arms arranged between a truck chassis and a workbench, and a plurality of scissor arms are matched to form a scissor mechanism; a hydraulic rod is arranged in the shear fork lifting mechanism and hinged to an upper connecting rod and a lower connecting rod through bolts, a falling speed reduction protection device is arranged on the rear half portion of the hydraulic rod, the characteristic that expansive fluid in non-Newtonian fluid is sensitive to the shear speed is utilized, the viscosity of the expansive fluid is increased along with the increase of the shear speed, and when the emergency situation that an oil pipe bursts occurs, the shear fork lifting mechanism can fall down. The falling speed reduction protection device is used for reducing the falling speed, and falling accidents are avoided.

    本申请提供一种飞机维护地面台车,包括:卡车底盘;工作台,设置于剪叉升降机构的上方,与剪叉升降机构一端铰接连接,另一端滑动连接;剪叉升降机构,设置于卡车底盘上;其特征在于,所述剪叉升降机构包括:剪叉臂,设置在卡车底盘和工作台之间,多根剪叉臂配合形成剪叉机构;剪叉升降机构内设置液压杆,通过螺栓与上连接杆和下连接杆铰接,在液压杆后半部设置坠落减速保护装置,利用非牛顿流体中胀流性流体具有剪切速度敏感的特性,其随剪切速度增大而粘性增大,实现了当发生油管爆裂紧急情况时,利用坠落减速保护装置减缓下降速度,避免坠落事故的发生。
