The invention provides a front jack structure and a design principle thereof, and relates to the technical field of mechanical equipment design. The front jack structure comprises a supporting mechanism, a three-stage actuator cylinder, a movable top rod and a hydraulic oil tank. The three-stage actuator cylinder is arranged in the middle of the supporting mechanism. The movable top rod is arranged at the top end of the three-stage actuator cylinder. The hydraulic oil tank is arranged on the right side of the three-stage actuator cylinder. The supporting mechanism and the three-stage actuatorcylinder are connected through a lug piece. The three-stage actuator cylinder comprises a piston rod device, an adjusting joint and a spring device. The spring device is arranged in the middle of thethree-stage actuator cylinder. The adjusting joint is arranged above the spring device. The piston rod device comprises a first piston rod, a second piston rod and a third piston rod. The three groupsof piston rods are sequentially arranged on the right side of the interior of the three-stage actuator cylinder outwards. The front jack structure is simple in structure, high in practicability, convenient to maintain and stable, reliable and flexible in operation.
Description
technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a front jack structure and its design principle. Background technique [0002] The aircraft hydraulic wheel jack is an important equipment for aircraft take-off. When the aircraft is leveling, replacing the wheel, etc., it is supported on the wheel of the aircraft to support the lifting of the aircraft. The existing hydraulic jack has difficulty in replacing parts. , The problem of slipping during the jacking up process has caused a certain impact on the normal work of the aircraft and the safety of the operators. [0003] Therefore, a technical problem that needs to be solved urgently is: how to innovatively propose an effective measure to meet the needs of practical applications. Contents of the invention [0004] In view of the deficiencies in the above problems, the present invention provides a front jack structure and its design principles, which make it simp...
