Multi-degree-of-freedom wing front-end working ladder

Abstract

The invention discloses a multi-degree-of-freedom wing front-end working ladder. The working ladder comprises a base platform, a Y-direction moving platform, a Y-direction driving mechanism, a Z-direction rotating platform, a rotating driving mechanism, an X-direction overturning device, an overturning driving mechanism and an overturning ladder assembly, wherein the Y-direction moving platform is connected with the base platform, a motor drives a gear to rotate and is meshed with a rack on the Y-direction moving platform to drive the moving platform to horizontally move front and back in the Y direction, the Z-direction rotating platform is connected with the Y-direction moving platform, a motor on the Z-direction rotating platform drives a gear to rotate to be meshed with an arc rack on the Y-direction moving platform, the Z-direction rotating platform is driven to rotate in the Z direction around a rotating shaft, the X-direction overturning device is fixed to two sides of the Z-direction rotating platform, the overturning ladder assembly is connected with a first rotating shaft base and a second rotating shaft base of the X-direction overturning device through rotating shafts on the two sides, and the overturning ladder assembly is driven by a motor fixed to the first rotating shaft base to move around the rotating shafts to achieve rotation in the X direction. Through the matching mode of various mechanical structures, the multi-direction station requirement is met.

Description

technical field [0001] The application relates to the technical field of aircraft assembly, in particular to an auxiliary working ladder for flexible assembly used at the front end of an aircraft wing. Background technique [0002] With the increasing size and shape of new aircraft and the high production efficiency requirements, the station-type large-scale digital assembly work platform has become the key equipment in the aircraft assembly stage. In order to work on the upper surface of the aircraft fuselage and wings, the digital aircraft assembly work platform needs to design a large number of integrated boarding ladders. [0003] The large aircraft assembly platform cannot be evacuated or completely evacuated due to the limitation of the working area. Due to the height limitation of the fixed integrated boarding ladder, it will interfere with the fuselage and wings during the movement of the aircraft station, affecting the movement of the aircraft. . [0004] During t...

AI Technical Summary

Problems solved by technology

[0003] The large aircraft assembly platform cannot be evacuated or completely evacuated due to the limitation of the working area. Due to the height limitation of the fixed integrated boarding ladder, it will interfere with the fuselage and wings during the movement of the aircraft station, affecting the movement of the aircraft.

[0004] During the general assembly process of the aircraft, it is necessary to set up a working ladder at a specific position when assembling the front end of the wing. At this time, the height of the working ladder is much higher than that of the wing. Under the platform or outside the wing tip, when the wingspan of the aircraft is long and the space below the assembly platform is occupied, the operator needs to spend time and effort, and there are certain safety and quality risks
