The invention discloses a device for measuring the opening degree of a skid type undercarriage of a helicopter. The measuring scale is composed of a plurality of mutually nested measuring sections and can stretch out and draw back horizontally, the two clamping structures can be clamped on sliding pipes on the left side and the right side of the skid type undercarriage respectively, and positioning pins matched with the clamping structures are arranged at the bottoms of the two measuring sections at the ends of the left side and the right side of the measuring scale. The opening degree can be measured by adjusting each measuring section to coincide with the center line of the symmetry axis of the helicopter. After the structure is adopted, accurate reference positioning is realized, on the basis, each measuring section is adjusted to coincide with the central line of the symmetry axis of the helicopter, then the opening degree can be measured, and due to the ingenious structural design, not only is the measurement very convenient, but also an accurate measurement result can be ensured.

    本发明公开了一种直升机滑橇式起落架张开度测量装置。它包括由多节相互嵌套的测量节所构成的能够水平伸缩的测量尺以及能够分别卡接在滑橇式起落架左右两侧的滑管上的两个卡接结构,测量尺的左右两侧端部的两节测量节的底部均设置有与卡接结构配合的定位销,通过调节各节测量节与直升机的对称轴中心线重合,进而能够对张开度进行测量。采用上述的结构后,实现了准确的基准定位,在此基础上再通过调节各节测量节与直升机的对称轴中心线重合,进而能够对张开度进行测量,其巧妙地结构设计,不但测量十分方便,而且能够保证准确的测量结果。
