Description
Technical field
The present invention relates to aviation safety field, more particularly, relate to a kind of refitting and drop out machine safety gear.
Background technology
Refitting air-drop traction lock, for airdrop platform is fixed to aircraft central guide rail, limits the motion of airdrop platform fore-and-aft direction and left and right directions, and removes fixing on central guide rail when extraction parachute works; And turn to startup main chute system in system traction control extraction parachute system instantaneously of disembarking.
After extraction parachute throwing umbrella is opened, under the effect of extraction parachute power, traction and locking lever assembly sway, cut off shear pin, drive piston rod to move up, remove the locking to whole aerial delivery system, under the effect of tractive force, aerial delivery system is to the slippage of aircraft rear deck simultaneously.The aerial delivery system back rest will slippage go out aircraft cabin time, aircraft roller clashes into rocking arm makes bar; rocking arm is made bar and pulled disengagement cable; unlock lever sways under the effect of disengagement cable; traction and the constraint of locking lever module cancels; under the effect of tractive force, depart from traction lock main body, aerial delivery system leaves aircraft simultaneously.
If existing traction lock unlock lever, disengagement cable or rocking arm in cargo extraction are made bar and are accidentally hit or vibrational excitation, will in aircraft pre-cooling main chute system, cause and drop unsuccessfully or even more serious air crash accident.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of refitting to drop out machine safety gear, and traction lock is not by the problem surprisingly excited in traction cargo extraction effectively can to solve airdrop platform, and structure is simple, and cost is lower.
The technical solution adopted for the present invention to solve the technical problems is: machine safety gear is dropped out in a kind of refitting of structure, be arranged on the traction lock of airdrop platform, described traction lock is provided with traction lock rocking arm, go out machine safety gear and comprise safety gear rotating shaft, safety gear rocking arm, Rocker connector and safety gear roller, safety gear rocking arm is arranged on traction lock by safety gear rotating shaft, safety gear rocking arm upper end is connected with traction lock rocking arm by Rocker connector, safety gear rocking arm upper end is also made bar by disengagement cable with back rest rocking arm and is connected, safety gear rocking arm lower end is provided with safety gear roller, described safety gear roller is pressed on aircraft central guide rail, the path that rotates clockwise of described safety gear rocking arm is provided with constraint block, described safety gear rocking arm is also connected with extension spring, described disengagement cable provides the power that described safety gear rocking arm is rotated counterclockwise, described extension spring provides the power that described safety gear rocking arm is rotated clockwise.
In such scheme, described aircraft central guide rail be provided with beat bar roller, after airdrop platform goes out machine, back rest rocking arm beat bar clash into aircraft beat bar roller, back rest rocking arm beat bar rotation.
In such scheme, the junction of described safety gear rocking arm and disengagement cable is provided with breach.
In such scheme, described traction lock rocking arm and Rocker connector place are provided with breach.
Implement refitting of the present invention and drop out machine safety gear, there is following beneficial effect:
The present invention resets, and to drop out machine safety gear structure simple, easy to operate, laborsavingly to save time, reliability is higher, cost is lower, and scantling of structure is less, do not limit by installation site, be not only applicable to cargo airdrop system and also can be used in without cargo airdrop system, therefore practicality is better, be easy to apply, there is larger practical value.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the integral structure schematic diagram after the installation of machine safety gear is dropped out in refitting;
Fig. 2 is the partial schematic diagram that machine safety gear is dropped out in refitting.
Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As shown in Figure 1 and Figure 2, the present invention resets and drops out machine safety gear, is arranged on the traction lock 7 of airdrop platform 13.Traction lock 7 is provided with traction lock rocking arm 8, goes out machine safety gear and comprises safety gear rotating shaft 2, safety gear rocking arm 1, Rocker connector 3 and safety gear roller 6.
Safety gear rocking arm 1 is arranged on traction lock 7 by safety gear rotating shaft 2.Safety gear rocking arm 1 upper end is connected with traction lock rocking arm 8 by Rocker connector 3, and safety gear rocking arm 1 upper end is also made bar 10 by disengagement cable 9 and back rest rocking arm and is connected.Safety gear rocking arm 1 lower end is provided with safety gear roller 6, and safety gear roller 6 is pressed on aircraft central guide rail 11.The path that rotates clockwise of safety gear rocking arm 1 is provided with constraint block 5.Safety gear rocking arm 1 is also connected with extension spring 4, and disengagement cable 9 provides the power that safety gear rocking arm 1 is rotated counterclockwise, and extension spring 4 provides the power that safety gear rocking arm 1 is rotated clockwise.Aircraft central guide rail 11 is provided with beats bar roller 12, and after airdrop platform 13 goes out machine, what back rest rocking arm beat that bar 10 clashes into aircraft beats bar roller 12, and back rest rocking arm is made bar 10 and rotated.Safety gear rocking arm 1 is provided with breach with the junction of disengagement cable 9.Traction lock rocking arm 8 and Rocker connector 3 place are provided with breach.
Safety gear rocking arm 1 retrains spacing due to aircraft central guide rail 11, cannot left-hand revolution, safety gear rocking arm 1 simultaneously also restrained piece 5 spacing, cannot clickwise.Even if back rest rocking arm is made bar 10 and pulled disengagement cable 9 due to vibration or shock, only disengagement cable 9 can be caused to rupture, pulling force cannot be delivered on traction lock rocking arm 8, and traction lock 7 can not be caused to excite disengaging.After airdrop platform 13 goes out machine, what back rest rocking arm beat that bar 10 clashes into aircraft beats bar roller 12, back rest rocking arm is made bar 10 and is rotated, now aerial delivery system traction lock 7 has departed from aircraft central guide rail 11 and has gone out machine, safety gear rocking arm 1 constraint relief is free to rotate, and pulling force is delivered on the traction lock rocking arm 8 of traction lock 7 by Rocker connector 3, opens traction lock 7, realize detachment function, resetted by the extension spring 4 on safety gear rocking arm 1 after traction lock 7 has worked.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, also can make a lot of form, these all belong within protection of the present invention.
