Description
Technical field
The present invention relates to aviation security field, more particularly, it relates to machine release mechanism is dropped out in a kind of refitting.
Background technology
Refitting air-drop traction lock is used to for airdrop platform to be fixed to aircraft central guide rail, limits airdrop platform fore-and-aft direction
With the motion of left and right directions, and fixation on central guide rail is released when extraction parachute works；And disembark wink in system traction
Between control extraction parachute system and turn to start main chute system.
Extraction parachute is thrown after umbrella opening, in the presence of extraction parachute power, is drawn and locking lever component pivoting, and cut-out is cut
Pin is cut, while driving piston rod to move up, the locking to whole aerial delivery system, the aerial delivery system in the presence of pull strength is released
To aircraft rear deck sliding.When the aerial delivery system back rest will slide out aircraft cabin, aircraft roller clashes into rocking arm makes bar, and rocking arm is beaten
Bar pulls disengagement cable, the pivoting in the presence of disengagement cable of unlocking lever, traction and the constraint of locking lever module cancels, is leading
Depart from traction lock main body in the presence of gravitation, while aerial delivery system leaves aircraft.
Existing traction lock is in cargo extraction if unlocking lever, disengagement cable or rocking arm make bar and be accidentally hit or vibrate
Excite, will in aircraft pre-cooling main chute system, cause air-drop failure or even more serious air crash accident.
The content of the invention
The technical problem to be solved in the present invention is, there is provided machine release mechanism is dropped out in one kind refitting, can be with effectively solving
The airdrop platform problem that traction lock is not surprisingly excited during machine is pulled out, and simple structure, cost is relatively low.
The technical solution adopted for the present invention to solve the technical problems is：Machine release mechanism is dropped out in a kind of refitting of construction,
On the traction lock of airdrop platform, the traction lock is provided with traction lock rocking arm, goes out machine release mechanism including release mechanism
Rotating shaft, release mechanism rocking arm, Rocker connector and release mechanism roller, release mechanism rocking arm is arranged on by release mechanism rotating shaft
On traction lock, release mechanism rocking arm upper end is connected by Rocker connector with traction lock rocking arm, and release mechanism rocking arm upper end is also
Bar is made by disengagement cable with back rest rocking arm to be connected, release mechanism rocking arm lower end is provided with release mechanism roller, the safe machine
Structure roller is pressed on aircraft central guide rail, and the clockwise rotation path of the release mechanism rocking arm is provided with constraint block, the peace
Full mechanism rocking arm is also connected with extension spring, and the disengagement cable provides the power for rotating counterclockwise the release mechanism rocking arm, the drawing
Spring provides the power for rotating clockwise the release mechanism rocking arm.
In such scheme, the aircraft central guide rail is provided with beats bar roller, and airdrop platform goes out after machine, and back rest rocking arm makes bar
Clash into aircraft beats bar roller, and back rest rocking arm plays bar rotation.
In such scheme, the release mechanism rocking arm is provided with breach with the junction of disengagement cable.
In such scheme, the traction lock rocking arm is provided with breach with the junction of Rocker connector.
Machine release mechanism is dropped out in the refitting for implementing the present invention, is had the advantages that：
Machine release mechanism simple structure is dropped out in present invention refitting, it is easy to operate, laborsaving save time, reliability it is higher, cost
It is relatively low, and physical dimension is less, is not limited by installation site, is applicable not only to cargo airdrop system and also can be used in without load bed
Aerial delivery system, therefore practicality is preferable, it is easy to popularization and application, with larger practical value.
Description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing：
Fig. 1 is that the overall structure diagram after machine release mechanism is installed is dropped out in refitting；
Fig. 2 is the partial schematic diagram that machine release mechanism is dropped out in refitting.
Specific embodiment
In order to be more clearly understood to the technical characteristic of the present invention, purpose and effect, now compare accompanying drawing and describe in detail
The specific embodiment of the present invention.
As shown in Figure 1 and Figure 2, machine release mechanism is dropped out in present invention refitting, on the traction lock 7 of airdrop platform 13.
Traction lock 7 is provided with traction lock rocking arm 8, goes out machine release mechanism and connects including release mechanism rotating shaft 2, release mechanism rocking arm 1, rocking arm
Part 3 and release mechanism roller 6.
Release mechanism rocking arm 1 is arranged on traction lock 7 by release mechanism rotating shaft 2.The upper end of release mechanism rocking arm 1 is by shaking
Arm connector 3 is connected with traction lock rocking arm 8, and the phase of bar 10 is also beaten in the upper end of release mechanism rocking arm 1 by disengagement cable 9 with back rest rocking arm
Connection.The lower end of release mechanism rocking arm 1 is provided with release mechanism roller 6, and release mechanism roller 6 is pressed on aircraft central guide rail 11.
The clockwise rotation path of release mechanism rocking arm 1 is provided with constraint block 5.Release mechanism rocking arm 1 is also connected with extension spring 4, disengagement cable 9
Offer makes the power that release mechanism rocking arm 1 is rotated counterclockwise, extension spring 4 provide the power for rotating clockwise release mechanism rocking arm 1.Aircraft
Central guide rail 11 is provided with beats bar roller 12, and airdrop platform 13 goes out after machine, and what back rest rocking arm made the shock aircraft of bar 10 beats bar roller
12, back rest rocking arm is made bar 10 and is rotated.Release mechanism rocking arm 1 is provided with breach with the junction of disengagement cable 9.Traction lock rocking arm 8 with shake
The junction of arm connector 3 is provided with breach.
Release mechanism rocking arm 1 constrains spacing due to aircraft central guide rail 11, it is impossible to rotate counterclockwise, release mechanism rocking arm 1
Simultaneously also restrained piece it is 5 spacing, it is impossible to turn clockwise.Even if back rest rocking arm makes bar 10 and pulls and free due to vibrate or clashing into
Rope 9, only can cause disengagement cable 9 to rupture, and pulling force cannot be delivered on traction lock rocking arm 8, do not resulted in traction lock 7 and excited disengaging.
After airdrop platform 13 goes out machine, back rest rocking arm makes bar 10 and clashes into aircraft and beats bar roller 12, and back rest rocking arm is made bar 10 and rotated, now
Aerial delivery system traction lock 7 has been detached from aircraft central guide rail 11 and goes out machine, and the constraint relief of release mechanism rocking arm 1 is free to rotate, draws
Power can be delivered on the traction lock rocking arm 8 of traction lock 7 by Rocker connector 3, open traction lock 7, realize detachment function, drawn
Resetted by the extension spring 4 on release mechanism rocking arm 1 after the completion of the work of lock 7.
Embodiments of the invention are described above in conjunction with accompanying drawing, but be the invention is not limited in above-mentioned concrete
Embodiment, above-mentioned specific embodiment is only schematic, rather than restricted, one of ordinary skill in the art
Under the enlightenment of the present invention, in the case of without departing from present inventive concept and scope of the claimed protection, can also make a lot
Form, these are belonged within the protection of the present invention.
