First solenoid directional control valve 4-1 of the invention makes in no power between the first accumulator 3-1 and the first hydraulic tube 5-1
Channel disconnect, the first solenoid directional control valve 4-1 be powered when so that the channel between the first accumulator 3-1 and the first hydraulic tube 5-1
Connection；Hydraulic oil inside the first piston hydraulic cylinder 2-1 or the first hydraulic tube 5-1 when oil starvation, inside the first accumulator 3-1
It can be added in the first piston hydraulic cylinder 2-1 and the first hydraulic tube 5-1 under the pressure effect of accumulator itself, fill it
Full hydraulic oil.
Similarly, the second solenoid directional control valve 4-2 makes in no power between the second accumulator 3-2 and the second hydraulic tube 5-2
Channel disconnects, when the second solenoid directional control valve 4-2 is powered, so that the channel between the second accumulator 3-2 and the second hydraulic tube 5-2 connects
It is logical；Inside the second piston hydraulic cylinder 2-2 or the second hydraulic tube 5-2 when oil starvation, the hydraulic oil inside the second accumulator 3 is storing
It can be added in the second piston hydraulic cylinder 2-2 and the second hydraulic tube 5-2 under the pressure effect of device itself, make it full of liquid
Pressure oil.
First piston hydraulic cylinder 2-1 and first launches the connecting rod connection of driving device 1-1, therefore when the first dispensing driving
When device 1-1 is moved, the piston rod movement of the first piston hydraulic cylinder 2-1 will drive, so that in the first piston hydraulic cylinder 2-1
Hydraulic oil the second piston hydraulic cylinder 2-2 is flowed by oil outlet and the second hydraulic tube 5-2, vice versa, the second dual-active
Hydraulic oil in plug hydraulic cylinder 2-2 can flow into the first piston hydraulic cylinder 2-1 by oil outlet and the first hydraulic tube 5-1；
Since the sectional area of two hydraulic cylinder with double piston rods is equal, movement velocity is identical, so that the first of cargo hook launches driving dress
The movement velocity for setting the dispensing of 1-1 and second driving device 1-2 is identical.
When cargo is linked up with perpendicular to course swing, the first hydraulic tube 5-1 and the second hydraulic tube 5-2 are linked up with cargo
It swings, when cargo hook in front and back swings asynchronous, the first hydraulic tube 5-1 and the second hydraulic tube 5-2 can do the bending of adaptability.
Its specific course of work is as follows, and the first of cargo hooking device launches driving device 1-1 when cargo hook is launched
It is rotated simultaneously with the second dispensing driving device 1-2, launches driving device when the speed that first launches driving device 1-1 is greater than second
When the speed of 1-2, first, which launches driving device 1-1, drives the hydraulic oil in the first piston hydraulic cylinder 2-1 to be pressed into the second dual-active
Hydraulic cylinder 2-2 is filled in, to push the second piston hydraulic cylinder 2-2 to launch driving device 1-2 by piston driving second with identical
Speed movement.
Similarly, when the speed of the second dispensing driving device 1-2 has the tendency that launching driving device 1-1 greater than first, the
Two, which launch driving device 1-2, drives the hydraulic oil in the second piston hydraulic cylinder 2-2 to be pressed into the first piston hydraulic cylinder 2-1, with
It pushes the first piston hydraulic cylinder 2-1 that the first dispensing driving device 1-1 is driven to move with identical speed, while driving first to hang
Hook 7-1 movement.
When the second dispensing driving device 1-2 failure can not provide power, first, which launches driving device 1-1, drives first pair
Piston hydraulic cylinder 2-1 is moved upwards, and the hydraulic oil in the first piston hydraulic cylinder 2-1 is made to be pressed into the second piston hydraulic cylinder 2-2
It is interior, push the second piston hydraulic cylinder 2-2 to move upwards, the second piston hydraulic cylinder 2-2 drives second to launch driving device 1-2
It moves synchronously, the velocity of rotation for making the first dispensing driving device 1-1 and second launch driving device 1-2 is identical.
When first launches driving device 1-1 failure, the second dispensing driving device 1-2 can also push the in the same way
One dispensing driving device 1-1 is moved synchronously.
In replacement, the first piston hydraulic cylinder 2-1 of disassembly, the second piston hydraulic cylinder 2-2, the first hydraulic tube 5-1 or the
It when two hydraulic tube 5-2, has few hydraulic fluid leak and comes out, if not carrying out supplement chance to hydraulic oil causes two dual-actives
The movement for filling in hydraulic cylinder is asynchronous.
The above problem occurs in order to prevent, and each synchronization mechanism first gives the electricity of the first solenoid directional control valve 4-1 and second using preceding
Magnetic reversal valve 4-2 is powered, the first accumulator 3-1 and the second accumulator 3-2 respectively with the first hydraulic tube 5-1 and the second hydraulic tube 5-
2 connect, as the first piston hydraulic cylinder 2-1, the second piston hydraulic cylinder 2-2, the first hydraulic tube 5-1 or the second hydraulic tube 5-2
When lacking hydraulic oil, the hydraulic oil in the first accumulator 3-1 and the second accumulator 3-2 can be under the action of accumulator internal pressure
It is automatically replenished in hydraulic cylinder and hydraulic tube.After having supplemented hydraulic oil, the first solenoid directional control valve 4-1 power-off makes the first hydraulic tube 5-
1 and first accumulator 3-1 channel disconnect, the second solenoid directional control valve 4-2 power-off make the second hydraulic tube 5-2 and the second accumulator 3-
2 channel disconnects, and synchronization mechanism can work normally.
When being caused cargo hook perpendicular to course swing by air-flow or helicopter attitude variation when helicopter flight, even
The the first hydraulic tube 5-1 and the second hydraulic tube 5-2 for connecing two piston hydraulic cylinders are swung, front and back cargo with cargo hook
When hook swings asynchronous, the first hydraulic tube 5-1 and the bending of the second hydraulic tube 5-2 adaptability are without damaging.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.

It 2-3) is fixedly connected with the front end of the second hook (7-2), the rear end of the second hook (7-2) is used for Suspended Cargo, the second hook (7-
2) it is hinged with the 4th shaft (6-2-4).
9. a kind of bidirectional hydraulic synchronization mechanism of helicopter two point hanging according to claim 8, which is characterized in that second
Idler wheel (6-2-1) is placed on the second arc surface (1-2-3).
10. a kind of bidirectional hydraulic synchronization mechanism based on helicopter two point described in any one of claim 1-9 hanging is same
One step process, which is characterized in that when first, which launches driving device (1-1) movement velocity, is greater than the second dispensing driving device (1-2),
First launches the piston rod movement that driving device (1-1) drives the first piston hydraulic cylinder (2-1), the first piston hydraulic cylinder
Hydraulic oil in (2-1) is flowed into the second piston hydraulic cylinder (2-2) by oil outlet and the second hydraulic tube (5-2), pushes the
Two piston hydraulic cylinders (2-2) move synchronously, and then the second movement velocity for launching driving device (1-2) and first is pushed to launch
The movement velocity of driving device (1-1) is identical；
When second, which launches driving device (1-2) movement velocity, is greater than the first dispensing driving device (1-1), second launches driving dress
Set the piston rod movement that (1-2) drives the second piston hydraulic cylinder (2-2), the hydraulic oil in the second piston hydraulic cylinder (2-2)
It is flowed into the first piston hydraulic cylinder (2-1) by oil outlet and the first hydraulic tube (5-1), pushes the first piston hydraulic cylinder
(2-1) is moved synchronously, and then the first movement velocity for launching driving device (1-1) and second is pushed to launch driving device (1-2)
Movement velocity it is identical.
