DEVICE FOR HOISTING FLYING VEHICLE

摘要

FIELD: hoisting flying vehicles at ground servicing. ^ SUBSTANCE: proposed device has two pairs of supports: one pair of supports consists of telescopic actuating hydraulic cylinders mounted on bearing plates and located in zone of main undercarriage legs connected with pumping station by means of flexible pipe lines for individual parallel hoisting of one of supports. Other pair of supports consists of mechanical jacks located in zone of nose leg of flying vehicle undercarriage. Pumping station may be provided with pump manual drive. Telescopic actuating hydraulic cylinder is provided with extensible rod-cylinder with central extensible rod mounted inside it. Rigidly mounted on this rod is loading head. Outer surfaces of rods are provided with trapezoidal threads on which respective locking nuts are screwed; these nuts rest against end faces of cylinders engageable with them; they are provided with keyways engageable with keys secured in these cylinders. Jacks are of two-screw type at linear motion of central screw performed by means of outer screw connecting the central screw with jack body by means of kinematic chain. Jack loading head may be lifted from central screw. Bearing plates are provided with tripods on whose lugs bearing shoes adjustable in height are mounted for vertical leveling of supports at contact with ground; at least one of tripod lugs is provided with level gauge for check of horizontal position of bearing plate. Bearing plates are provided with motion rolls connected with ends of two lugs of tripod and located beyond shoes; end of third lug is connected with draught bar. Bearing plates of hydraulic cylinders have mounting seats for securing and transportation of jacks. ^ EFFECT: enhanced safety and quick hoisting of flying vehicle. ^ 8 cl, 4 dwg
