The invention provides a rocker arm pulling-out device for airplane air inlet passage protective fence which can reduce the difficulty of pulling out a protective fence rocker arm, can reduce damage to the protective fence rocker arm and can guarantee the quality of decomposition work. The device comprises an impact hammer, a threaded sliding rod, a handle, an expansion sleeve and an expansion head, when in use, an airplane air inlet protective fence rocker arm is connected with the expansion head then the handle is rotated to enable the expansion sleeve to move in the axial direction of the threaded sliding rod, and the airplane airway protective fence rocker arm is clamped, and finally, external acting force acts on the impact hammer, the impact hammer repeatedly impacts the limiting boss at the end of the threaded sliding rod, and therefore the air inlet passage protective fence rocker arm connected with the expansion head is continuously pulled out.

    本发明提供一种飞机进气道防护栅摇臂拔出装置,能够降低防护栅摇臂拔出的难度,减少防护栅摇臂的损伤,保证了分解工作的质量。包括:撞击锤、螺纹滑杆、手柄、膨胀套筒和膨胀头;使用时将飞机进气道防护栅摇臂与所述膨胀头;然后旋转所述手柄,使所述膨胀套筒延螺纹滑杆轴向运动,夹紧所述飞机气道防护栅摇臂夹紧;最后将外部作用力作用于撞击锤,通过所述撞击锤反复撞击所述螺纹滑杆端部的限位凸台,从而将所述膨胀头所连接的进气道防护栅摇臂不断拔出。
