Problems solved by technology

[0002] At present, in the process of aircraft assembly or use, if there is a problem with one of the parts, the designer generally adopts the method of replacing the part or component as a whole, but for an assembly with a simple structure and small parts, the overall replacement is time-consuming and laborious. The degree of freedom of rotation of the parts is extremely limited, and the entire replacement execution part is also bloated and bulky, especially the replacement of large aircraft fuselages is more difficult, the operating space for workers is small, and the movement of complex mechanisms takes up a lot of use space

Embodiment Construction

[0014] Such as figure 1 As shown, a device that facilitates the replacement of vulnerable parts, the end 1 is connected with a threaded rod 3, the threaded rod 3 is provided with a safety hole 2, the outer circumference of the lower half of the threaded rod 3 is provided with a steel wire rope 4, and the lower end of the threaded rod 3 Connect with steel pipe 5. Through the safety hole 2 of the terminal 1, it is fixedly connected with the bottom of the rear fuselage of the aircraft, and is used for the contact and friction between the aircraft and the ground during the taxiing phase, and plays a role of discharge.

[0015] The end head 1 is detachably connected to the threaded rod 3 .

[0016] The centerlines of the end head 1, the threaded rod 3 and the steel pipe 5 coincide.

[0017] The upper end of the steel pipe 5 is in contact with the steel wire rope 4 .

[0018] The safety holes 2 are located on both sides of the center line of the threaded rod 3 .

[0019] Pass th...

Abstract

The invention relates to a device for replacing a fragile part conveniently. A tip is detachably connected with a threaded rod. Under the condition that the part makes contact with the ground and consequentially is abraded seriously when an airplane glides, only the portion, below the threaded rod, of the part needs to be replaced, replacement is convenient and fast, part waste is avoided, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a device for convenient replacement of vulnerable parts, which belongs to the field of aircraft assembly and manufacturing. Background technique [0002] At present, in the process of aircraft assembly or use, if there is a problem with one of the parts, the designer generally adopts the method of replacing the part or component as a whole, but for an assembly with a simple structure and small parts, the overall replacement is time-consuming and laborious. The degree of freedom of rotation of the parts is extremely limited, and the entire replacement execution part is also bloated and bulky, especially the replacement of large aircraft fuselages is more difficult, the operating space for workers is small, and the complex mechanism movement takes up a lot of space. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device that facilitates the replacement of vulnerable...
