Problems solved by technology

[0005] In order to overcome the space limitation of the small helicopter maintenance station, large lifting equipment cannot directly enter the maintenance warehouse. When hoisting and lifting the rotor, several maintenance personnel are required to flip the rotor in all directions. After the fuselage is lifted, it is necessary to temporarily assemble the side support frame to fix the helicopter fuselage. The steps are cumbersome and time-consuming. The technical problem to be solved is: to provide a mechanical lifter for helicopter repair and maintenance. heavy device

Abstract

The invention relates to the field of helicopter maintenance, in particular to a mechanical lifting device for helicopter repair and maintenance. In order to solve the technical problem, the mechanical lifting device for helicopter repair and maintenance is provided. According to the technical scheme, the mechanical lifting device for helicopter repair and maintenance comprises a fixed lifting unit, a component lifting assembly, a support table, a wheeled movable chassis, a master control console, a first side ladder, a second side ladder, an auxiliary control console and an extension tripod. The mechanical lifting device is automatically attached to a helicopter fuselage so that the helicopter fuselage is clamped, fixed and lifted, and large displacement of the helicopter in the maintenance process is avoided; other components, such as rotor wings and engines, can be lifted and conveyed; in addition, a micro-angle adjusting component is added, and therefore the rotor wing mounting work is higher in adjusting freedom degree; and the rotor wing mounting flexibility of maintenance personnel is improved.

Description

technical field [0001] The invention relates to the field of helicopter maintenance, in particular to a mechanical lifting device used for helicopter repair and maintenance. Background technique [0002] Civil helicopters have good market prospects in my country, and the main reason for the high failure rate of civil helicopters is that, on the one hand, the helicopter has more rotating parts than fixed-wing aircraft, so the load effect is complex, and the alternating load of the rotor and tail rotor is easy. It will cause the helicopter to vibrate and produce fatigue damage. In addition, the frequent collision of the landing gear will also make it more damaged. Therefore, the maintenance of the rotor part and the parts at the bottom of the fuselage has become one of the main items of civil helicopter repair and maintenance. [0003] A small civil helicopter has the characteristics of compact structure and simple structure. It is usually assembled by splicing several groups ...
