A sling structure for lifting and turning aircraft

Abstract

A lifting appliance structure used for lifting and overturning an aircraft comprises a front lifting fame, a front lifting arm, an L-shaped lifting beam, a rear lifting frame, a locking sliding block, a front lifting clasp and a rear lifting clasp. The front lifting frame is connected with the front lifting arm through a hinge. The vertical rod end of the L-shaped lifting beam is connected with the rear lifting frame through a hinge, and the transverse rod end of the L-shaped lifting beam is connected with the front lifting arm. The locking sliding block is located on the transverse rod of the L-shaped lifting beam, and a double-lifting lug is arranged at the bottom of the locking sliding block and connected with the front lifting clasp. The front lifting clasp and the rear lifting clasp are each divided into two parts, and through holes are formed between the two parts of the front lifting clasp and the two parts of the rear lifting clasp respectively, after assembly with a front end journal and a rear end journal of the aircraft is finished, the two parts of the front lifting clasp and the two parts of the rear lifting clasp are buckled and connected through bolts. According to the scheme of the lifting appliance, the overall truss-type structure with the hinged front part and the fixedly connected rear part is adopted, and the lifting appliance structure used for lifting and overturning the aircraft is convenient to operate, simple, reliable, high in universality and suitable for rapid lifting and overturning of various wing-fuselage combination aircrafts, launch vehicles and the like, and has broad application prospects in the field of aerospace.

Description

technical field [0001] The invention relates to a hanger structure used for lifting and turning over of an aircraft, which belongs to the field of aerospace. Background technique [0002] The spreader with integrated lifting and turning functions is one of the key technologies for rapid lifting, turning and erecting of winged aircraft and launch vehicles. The requirements for new fast lifting and turning spreaders are increasing at home and abroad. , The overturning spreader is still based on the flexible sling + truss structure, such as figure 1 , 2 As shown, traditional rockets or aircraft generally use two sets of cranes to cooperate with two sets of slings (aircraft 2 and traditional sling 4) to realize the horizontal lifting and turning up of the rocket. The stability of this hoisting method is poor. When the rocket is about to be completely erected, it is prone to shake and cause a large overload, and the position of the lifting point will generate a large stress, wh...
