Abstract
A kind of guard ring, shape are in " C " shape.There are the mounting blocks for connecting aircraft structure respectively on two ends of the guard ring opening；The wall thickness of the guard ring and axial height are 5mm, and the shape and size of inner ring can wrap up aircraft cable wire, and make between cable wire and the inner wall of guard ring that there are small―gap sutures.When replacing the cable assembly, guard ring is removed, and the cable assembly needed replacing and the cable assembly being replaced are connected to guiding traction with swivel nut.The cable assembly for needing to be replaced is removed again.It will be in the cable assembly access system circuit after replacement.The configuration of the present invention is simple, easy to operate, maintenance efficiency greatly improves, and one can be completed, and improves maintenance efficiency.
Description
Technical field
It is specifically a kind of for protecting the guard ring and the guard ring of cable wire the present invention relates to flight control control field
Installation method.
Background technique
Currently, aircraft flight control manipulation is still being used on a large scale with cable wire, and cable wire service life problem is still
In the presence of.It in aircraft life. cycle, needs to replace cable wire, guard ring is cable wire outer layer protection again, and replacement cable wire need to be from anti-
Extract out and penetrate in guard ring, cable wire in steerable system throughout aircraft everywhere, while replacement operation narrow space, difficulty are big.
A kind of cable wire regulating device of sectional wheel is disclosed in the utility model patent that notification number is CN204368412U.
It is difficult to the problem of adjusting by connecting which solves sectional wheel with cable wire, is adjustable the length and tension of cable wire, but at this
It cannot play the role of protection in cable movement.
A kind of cable wire sealing structure is disclosed in the utility model patent that notification number is CN204372160U.The cable wire is close
Seal structure can satisfy and reduce cable wire kinetic force of friction under airtight requirement, can play a protective role to the air pressure in different cabins,
But protection cannot be played the role of in the cable movement or in replacement.
Summary of the invention
To overcome replacement operation narrow space existing in the prior art, the big step of replacement difficulty, the invention proposes
A kind of guard ring.
Guard ring proposed by the present invention is in " C " shape.Mounting blocks are distinguished on two ends of the guard ring opening；The protection
The wall thickness of circle and axial height are 5mm, and the shape and size of inner ring can wrap up aircraft cable wire, and make cable wire and guard ring
Inner wall between there are small―gap sutures.
There are two the through-holes for connecting aircraft structure respectively on each mounting blocks, and make the center line of each through-hole
Perpendicular to the surface of the mounting blocks.
When replacing the cable assembly, remove the guard ring, and with swivel nut by the cable assembly needed replacing and
The cable assembly being replaced is connected to guiding traction.The cable assembly for needing to be replaced is removed again.By the cable wire group after replacement
In part access system circuit.Cable tension is adjusted by design requirement.By the protection snare on the cable assembly, and it will prevent
Guard ring is fixed with aircraft structure.After all replacement installations, marked at the connector of fixed protection circle and aircraft structure
Note, facilitates subsequent screw loosening inspection.
Currently, the flight control main transmission of most domestic Medium Plane still uses mechanical rope gearing,
And when aircraft inspects periodically maintenance, it has been found that fracture of wire phenomenon occurs in the cable assembly of mechanical rope gearing, in replacement steel
When rope component, the cable assembly that will be replaced is needed all to extract out from guard ring, the cable assembly newly replaced is worn again again
Entering in guard ring, process is tedious for maintenance maintenance,
For the present invention when replacing cable assembly, the radical that cable wire is penetrated in guard ring is different, and the process number of reduction is just different,
Wherein every cable wire can reduce by 2 installation procedures, and 1 disassembly is extracted process and 1 installation out from guard ring and penetrated from guard ring
Process, pass through that guard ring quantity is different according to cable assembly, the process number of reduction is just different, but can at least reduce by 2 sets of works
Sequence.Junction and guard ring card resistance between cable assembly are no longer worried when replacing cable assembly, after replacement, then by guard ring
Again it covers on whole cable wires.The configuration of the present invention is simple, easy to operate, maintenance efficiency greatly improves, and one can be complete
At improving maintenance efficiency.
In the prior art, 5 cable wires are replaced and need about 15min.Using the present invention, the time of same amount of cable wire is replaced
Shorten half, it is only necessary to 7min or so.When replacing cable wire, influenced by quantity, the operating space factor of aircraft utilization cable wire, individually
Guard ring penetrates that cable wire quantity is more, operating space is smaller, and it is more to save the time.
Detailed description of the invention
Fig. 1 is guard ring installation method schematic diagram.
Fig. 2 is guard ring structural schematic diagram.
In figure: 1. cable assemblies；2. guard ring；3. aircraft structure；4. screw；5. mounting blocks.
Specific embodiment
The present embodiment is a kind of protection coil structures and mounting means.
The guard ring 2 is in " C " shape.There are the mounting blocks of rectangle respectively on two ends of the guard ring opening；Each
There are two the through-holes for connecting aircraft structure respectively on mounting blocks, and make the central axis of each through-hole in the mounting blocks
Surface.The wall thickness of the guard ring and axial height are 5mm, and the shape and size of inner ring can wrap up aircraft cable wire, and make
There are small―gap sutures between cable wire and the inner wall of guard ring.The mounting plate of the guard ring is bonded with the mounting plane of aircraft structure.
The cross section of the guard ring is in rectangle, is made of aluminum alloy plate materials.
The installation through-hole there are four the equal 4.2mm in aperture, four lead to the hole site and institute are reserved in the aircraft structure 3
The lead to the hole site stated on each mounting blocks of guard ring is corresponding.
The screw 4 is that six square toes, half polished rod half-thread is M4 screw.
When the cable assembly 1 failure needs replacing, the mounting screw 4 of the guard ring 2 is first unclamped, institute is removed
The guard ring stated, and the cable assembly needed replacing and the cable assembly being replaced are connected to guiding traction with swivel nut.Again
Remove the cable assembly for needing to be replaced.It will be in the cable assembly access system circuit after replacement.Cable wire is adjusted by design requirement
Tension.By the protection snare on the cable assembly, and steel guard ring is fixed with aircraft structure.All replacement installations
After, it is marked at the connector of fixed protection circle and aircraft structure by Replacement procedure regulation, it is subsequent to facilitate
Screw loosening inspection.
The swivel nut is sleeve part.There are left hand thread and right-handed thread in the both ends of the swivel nut respectively, are used for two
Connection between cable assembly.
