The invention discloses a measuring device and a measuring method for measuring deformation of a pull rod on an airplane. The measuring device comprises: a sleeve capable of accommodating the pull rod, wherein the sleeve is sleeved on the pull rod in a manner of moving relative to the pull rod, the sleeve comprises a near end and a far end, the near end of the sleeve is a free end, and the far endof the sleeve is detachably fixed on the pull rod along the axial direction of the pull rod; a ruler frame, wherein the ruler frame is movably connected to the near end of the sleeve in the axial direction through a connecting piece, and the inner surface of the ruler frame is opposite to the outer surface of the pull rod; a capacitive grating sensor, wherein the capacitive grating sensor is usedfor measuring and receiving displacement information of the ruler frame, the capacitive grating sensor comprises a movable ruler part and a fixed ruler part, the movable ruler part is arranged on theinner surface of the ruler frame, the fixed ruler part is fixedly arranged on the outer surface of the pull rod, and a gap is formed between the movable ruler part and the fixed ruler part in the radial direction; and a fixing component, wherein the fixing component is configured to fix the ruler frame to the near end of the sleeve when the ruler frame moves to the position where the movable ruler part and the fixed ruler part coincide in the radial direction, so that the ruler frame and the sleeve can move together in the axial direction relative to the pull rod.

    一种用于测量飞机上的拉杆变形量的测量装置以及测量方法,包括:能够容纳拉杆的套筒,套筒以能够相对拉杆移动的方式套设于拉杆,套筒包括近端和远端,套筒的近端为自由端,套筒的远端沿拉杆的轴向可拆卸地固定于拉杆;尺框,尺框通过连接件沿轴向可移动地连接于套筒的近端,尺框的内表面与拉杆的外表面相对;容栅传感器,容栅传感器用于测量并接收尺框的位移的信息,容栅传感器包括动尺部和定尺部,动尺部设置于尺框的内表面,定尺部固定地设置于拉杆的外表面,动尺部与定尺部在径向上隔开间隙;固定构件,固定构件构造成当尺框移动至动尺部与定尺部在径向上重合的位置时,将尺框固定于套筒的近端,使得尺框能够与套筒一起相对拉杆轴向移动。
