The invention belongs to the field of aviation structure strength design, and particularly relates to a crane sliding rail connecting structure of a flat plate air-tight door. The hanger rail and the hanger rail support which do not bear the airtight load of the fuselage are designed according to the rigid motion relation between the nine sets of hanger rail supports and the airtight door and the hanger rail. The hanger rail support is divided into three sections for design, and the first section of variable-section I-shaped hanger rail 10 adopts the design form of one fixed hanger rail support and one movable hanger rail support; the second section of equal-section I-shaped hanger rail 11 adopts a design form of one fixed hanger rail support and four movable hanger rail supports; and the third section of the equal-section I-shaped hanger rail 12 adopts a design form of one fixed hanger rail support and one movable hanger rail support. Through the connection design relation among the hanger rail, the hanger rail support and the flat plate airtight door, decoupling of loads borne by the flat plate airtight door and the hanger rail under airtight loads is achieved, load transmission is clearer, and the use risk caused by airtight additional loads to the hanger rail support is avoided.
本申请属于航空结构强度设计领域,特别涉及一种平板气密门的吊车滑轨连接结构。通过对9组吊轨支座与气密门和吊轨之间的刚体运动关系,设计出了不承受机身气密载荷的吊轨和吊轨支座。将吊轨支座分成3段进行设计,第一段变剖面工字型吊轨10采用1个固定吊轨支座+1个可动吊轨支座的设计形式;第二段等剖面工字型吊轨11采用1个固定吊轨支座+4个可动吊轨支座的设计形式;第三段等剖面工字型吊轨12采用1个固定吊轨支座+1个可动吊轨支座的设计形式。本申请通过吊轨、吊轨支座、平板气密门之间的连接设计关系,实现了气密载荷下平板气密门和吊轨承受载荷的解耦,使得载荷传递更加清晰,避免了气密附加载荷对吊轨支座带来的使用风险。
