Now no rod-type aircraft tractor wheel holding mechanism application method provided by the invention is described below:
When needing using no rod-type aircraft tractor and this wheel holding mechanism towing aircraft, the main control first on tractor
Under the control of device, jack up hydraulic cylinder 11 on push rod shrink, thus drive principal arm 2 rear end around cross bar 3 be rotated down and in
Under it is skewed, the tilt angle of platform 1 further increases at the same time；Push this wheel holding mechanism to aircraft using tractor later
Preceding wheel 15 is turned out 90 ° when rear shelves 10 lean on nearby wheel 15 automatically and opens, and using the adjusting in principal arm 2 and moves
Power device come adjust telescopic arm 9 stretch out principal arm 2 outside length, to adapt to different size of preceding wheel 15；Enter to preceding wheel 15
When to space between two principal arms, 2 rear portion, automatic inwardly 90 ° of the rotation of shelves 10 after two, thus from rear side hold tightly before wheel 15；This
When auxiliary hydraulic cylinder 4 by adjusting the pivot angle of platform 1 come wheel 15 before assisting holding tightly.Later, the push rod on hydraulic cylinder 11 is jacked up
It is protruding, the rear portion of principal arm 2 is thus jacked up, jacks up height in 200mm or so, then tractor and wheel holding mechanism integrally move back
Wheel 15 rolls on turntable 7 before making.At the same time, under the control of master controller, the sliding block 6-1 on lock 6 is moved forward, thus
It unclamps latch hook 6-2 and can rotate, lock can be pushed when the traction pin shaft 6-4 on nose-gear is entered in latch hook 6-2
Hook 6-2 simultaneously pushes up block 6-3 in the groove 6-6 on nearly shell 6-5, and then sliding block moves back 6-1 and so that latch hook 6-2 is steeved and drive gear
Block 6-3 is moved in groove 6-6 and is held out against the traction front pin shaft 6-4., nose-gear and preceding wheel 15 are linked as with turntable 7 at this time
One.Then start pushing tow aircraft, during pushing tow, the block 12 of 7 front of turntable plays a major role, and thrust is passed by block 12
Wheel 15 before passing, to push aircraft to move back.In distraction procedure, tractive force mainly passes through lock 6 and passes to nose-gear,
To push aircraft mobile.
When turning, auxiliary hydraulic cylinder 4 can according to turning radius adjust platform 1 pivot angle, with balance turning when two before machine
The height of wheel 15 is different.
When aircraft is intended to disengage with tractor, under the control of master controller, the sliding block 6-1 on lock 6 is moved forward, by
This unclamps latch hook 6-2, and nose-gear pushes block 6-3 by inertia force, so that latch hook 6-2 be made to rotate, disengages connection.Then it pushes up
The push rod retraction on hydraulic cylinder 11 is played, the inclination angle of platform 1 increases, and final preceding wheel 15 is rolled down along the inclined-plane of turntable 7.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are because of the understanding, and the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
