The invention provides a lifting appliance suitable for a large-scale and large-slenderness-ratio aircraft, which is characterized in that a first lifting point and a second lifting point of a cruise stage are rigidly connected with a cruise-stage lifting beam through a first cruise-stage connecting piece and a second cruise-stage connecting piece respectively, and the cruise-stage lifting beam is connected with a first-stage lifting beam through a third cruise-stage connecting piece; the connecting lifting points of the third cruise-stage connecting piece and the cruise-stage lifting beam and the first-stage lifting beam can move in the axial direction of the aircraft; a first lifting point and a second lifting point of the boosting stage are connected with a first boosting stage connecting piece through a first boosting stage lifting belt and a second boosting stage lifting belt respectively, the first boosting stage connecting piece is hung on a first sliding piece and a second sliding piece, and the first sliding piece and the second sliding piece are in rigid connection with a first-stage lifting beam. And the connecting lifting point can move along the axial direction of the aircraft. The technical problem that in the prior art, hoisting risks exist in the hoisting process of a large-scale and large-slenderness-ratio aircraft can be solved.
本发明提供了一种适用于大尺度大长细比飞行器的吊具,巡航级的第一吊点和第二吊点分别通过第一巡航级连接件和第二巡航级连接件与巡航级吊梁刚性连接,巡航级吊梁通过第三巡航级连接件与一级吊梁连接,第三巡航级连接件与巡航级吊梁和一级吊梁的连接吊点可沿飞行器的轴向移动;助推级的第一吊点和第二吊点分别通过第一助推级吊带和第二助推级吊带与第一助推级连接件连接,第一助推级连接件吊挂于第一滑动件和第二滑动件上,第一滑动件和第二滑动件与一级吊梁刚性连接,且连接吊点可沿飞行器的轴向移动。本发明能够解决现有技术中大尺度大长细比飞行器起吊过程存在起吊风险的技术问题。
