The invention discloses a sliding rail mechanism for a helicopter sliding fairing and the helicopter sliding fairing, and the sliding rail mechanism comprises three sliding rails which are respectively two side sliding rails which are fixedly mounted on a power platform and are symmetrically arranged, and a middle sliding rail which is fixedly mounted on one side wall of a firewall; wherein all the sliding rails are installed in parallel in the heading direction, a dismounting and mounting opening is formed in the middle of each sliding rail, when a pulley at the corresponding position on the sliding fairing slides on the sliding rail at the corresponding position, the pulley is disengaged from and mounted in the dismounting and mounting opening, and a middle blanking cap assembly is arranged at the position of each dismounting and mounting opening; the pulley of the sliding fairing is prevented from being separated from the sliding rail at the corresponding position in the sliding process; each sliding rail is provided with a first limiting mechanism used for preventing a pulley at the corresponding position in the sliding fairing from disengaging from the disassembling and assembling opening position of the sliding rail. Each sliding rail is further provided with a second limiting mechanism used for limiting a pulley at the corresponding position in the sliding fairing to the disassembly and assembly opening position of the sliding rail. Each side sliding rail is provided with a buffering and limiting mechanism used for limiting a pulley at the corresponding position in the sliding fairing to the completely-opened position of the sliding fairing.
本发明公开一种用于直升机滑动整流罩的滑轨机构和直升机滑动整流罩,包括:3根滑轨,分别为:固定安装在动力平台上、且对称布设的2根侧部滑轨,固定安装在防火墙一侧侧壁上的中间滑轨;其中,每根滑轨均沿航向方向平行安装,且每根滑轨的中间位置均开设有拆装开口,用于滑动整流罩上相应位置的滑轮在对应位置的滑轨上滑动时,从拆装开口中脱出和装入,且每个拆装开口位置设置有中间堵盖组件,以防止滑动整流罩的滑轮在滑动过程中从对应位置的滑轨中脱出;每根滑轨上均设置有用于防止滑动整流罩中对应位置的滑轮从本滑轨的拆装开口位置脱出的第一限位机构;每根滑轨上还设置有用于将滑动整流罩中对应位置的滑轮限制在本滑轨的拆装开口位置的第二限位机构;且每根侧部滑轨上均设置有用于将滑动整流罩中对应位置的滑轮限制在滑动整流罩完全打开位置的缓冲及限位机构。
