The invention belongs to the field of helicopter structure design, and particularly relates to a helicopter mooring device and a design method thereof. According to the device, one end of the adapter is hinged to the mooring ring, the other part of the adapter is a circular shaft, and N1 guide blocks are symmetrically arranged on the side wall of the end, away from the mooring ring, of the circular shaft; external threads are arranged on the outer wall of the fixed sleeve; n1 guide grooves are symmetrically formed in the inner wall of the fixed sleeve, one end of each guide groove is sunken in the radial direction to form a stop block clamping groove, a guide block at the circular shaft end of the adapter penetrates through the fixed sleeve along the guide groove and then rotates, and a stop block is installed in the stop block clamping groove to axially limit the guide block; n2 limiting blocks are symmetrically arranged at one end of the outer wall of the fixed sleeve; n2 second guide grooves are symmetrically formed in the inner wall of the fixed bushing, and N2 clamping grooves are symmetrically formed in a non-guide-groove area at one end of the inner wall of the fixed bushing; the fixing sleeve penetrates through the fixing lining through the limiting block along the second guide groove and rotates to enable the limiting block to be clamped into the clamping groove for limiting. And the fixed bushing is mounted on a machine body structure through screw joint or interference fit.
本发明属于直升机结构设计领域,具体是一种直升机系留装置及其设计方法。装置关系如下:转接头一端与系留环铰接,另一部分为圆轴,圆轴远离系留环一端侧壁对称设有N1个导引块;固定套筒外壁设有外螺纹;固定套筒内壁对称设有N1个导引槽,导引槽一端沿径向凹陷形成挡块卡槽,转接头圆轴端的导引块沿导引槽穿过固定套筒后旋转,在挡块卡槽中安装挡块对导引块进行轴向限位;固定套筒外壁一端对称设有N2个限位块;固定衬套内壁对称设有N2个第二导引槽,且固定衬套内壁一端非导引槽区域对称设有N2个卡槽;固定套筒通过限位块沿第二导引槽穿过固定衬套,并旋转使得限位块卡入卡槽中进行限位;固定衬套通过螺接或过盈配合安装到机体结构上。
